    2016-06-01

    We report a case of sudden-onset abducens nerve palsy in a 15-year-old boy with ecchordosis physaliphora, a benign retroclival remnant that is usually asymptomatic. Most reported symptomatic cases have been treated with resection via craniotomy or endoscopic resection. Our patient recovered after a short course of oral corticosteroids, but the abducens nerve palsy recurred 6 months later. PMID:27060668

    Tumors of the posterior mediastinum are mostly neurogenic and could involve the intervertebral foramen and the medullary canal. We describe the case of a patient who underwent surgery for a nerve sheet tumor originating at the level of the right second neural root. Resection was associated with an incidental dural tear and cerebrospinal fluid leak that was promptly repaired. One week after surgery, horizontal diplopia occurred. A palsy of the left abducens nerve secondary to intracranial hypotension was diagnosed. We present the pathogenic cascade leading to this ocular complication after posterior mediastinal surgery. The surgical techniques to prevent this complication are discussed. PMID:25639411

    Kawasaki disease (KD) is a systemic vasculitis that can involve the nervous system, including the cranial nerves. Central nervous system findings, especially irritability, lethargy, and aseptic meningitis, occur in 1-30 % of KD patients (1). Cranial nerve palsies are seen rarely, and abducens nerve palsy has been reported in only three children. We describe a 2.5-year-old girl with incomplete KD who developed transient abducens nerve palsy after intravenous immunoglobulin (IVIG) treatment. PMID:27329470

    Abducens nerve palsy is a common clinical finding in neurology practice. In many instances, the origin is obvious and management straightforward; however, the list of possible etiologies and mimics is vast and diverse and diagnostic decisions can be challenging and even controversial. This is especially true when the abducens nerve is affected in isolation, since in the current era of cost-effective medicine, it is critical to accurately diagnose etiologies that may lead to major morbidity or mortality with efficiency. Topics for highlighted updates in this review include management of isolated abducens nerve palsy with a high likelihood of a microvascular ischemic etiology; common imaging pitfalls and current state-of-the-art neuroimaging; and abducens palsy mimics.

    Petrous apex masses can manifest with neurologic symptoms due to their involvement of various structures, including cranial nerves (CN) V and VI. The differential diagnosis of petrous masses is broad and includes a variety of both non-neoplastic and neoplastic lesions. We report a rare case of multiple myeloma confined to the right petrous apex, presenting with ipsilateral abducens and trigeminal nerve palsies. A 63-year-old woman presented with a 6-8 week history of facial numbness and a 2 week history of diplopia, with examination showing right-sided facial hypoesthesia in the CN V1-V3 region and right-sided lateral rectus palsy. MRI of the brain showed a solitary 2.0 cm lesion confined to the right petrous apex involving the right cavernous internal carotid artery and Meckel's cave. A transnasal biopsy showed a proliferation of plasmacytoid cells, which showed diffuse immunoreactivity with antibodies to CD138 and kappa, consistent with a plasma cell dyscrasia. A bone scan subsequently revealed multiple lytic bone lesions involving the skull, left humerus, bilateral femurs and possibly the L4 vertebral body. Bone marrow biopsy and serum laboratory results confirmed the diagnosis of kappa-type multiple myeloma. Although rare, multiple myeloma may initially present with petrous involvement and associated cranial nerve deficits. PMID:26602603

    The combination of abducens nerve palsy and ipsilateral Horner syndrome was first described by Parkinson and considered as a localizing sign of posterior cavernous sinus lesions. The authors present a case with right abducens nerve palsy with ipsilateral Horner syndrome in a patient with carotid-cavernous fistula because of head trauma. The patient was referred to the ophthalmology clinic with diplopia complaint after suffering a head trauma during a motorcycle accident. Cerebral angiography showed low-flow carotid-cavernous fistula. PMID:26468854

    Multiple cranial nerves palsies following a posterior fossa exploration confined to an extradural compartment is a rare clinical presentation. This case report describes a young man who developed a unilateral abducens and bilateral facial nerve palsies following a posterior fossa exploration confined to an extradural compartment. There are different theories to explain this presentation, but the exact mechanism remains unclear. We propose that this patient cranial nerve palsies developed following cerebrospinal fluid (CSF) leak, potentially as a consequence of rapid change in CSF dynamics. PMID:26951144

    2013-03-01

    Isolated abducens nerve paresis related to ruptured vertebral artery (VA) aneurysm is rare. It usually occurs bilaterally or ipsilaterally to the pathologic lesions. We report the case of a contralateral sixth nerve palsy following ruptured dissecting VA aneurysm. A 38-year-old man was admitted for the evaluation of a 6-day history of headache. Abnormalities were not seen on initial computed tomography (CT). On admission, the patient was alert and no signs reflecting neurologic deficits were noted. Time of flight magnetic resonance angiography revealed a fusiform dilatation of the right VA involving origin of the posterior inferior cerebellar artery. The patient suddenly suffered from severe headache with diplopia the day before the scheduled cerebral angiography. Neurologic examination disclosed nuchal rigidity and isolated left abducens nerve palsy. Emergent CT scan showed high density in the basal and prepontine cistern compatible with ruptured aneurismal hemorrhage. Right vertebral angiography illustrated a right VA dissecting aneurysm with prominent displaced vertebrobasilar artery to inferiorly on left side. Double-stent placement was conducted for the treatment of ruptured dissecting VA aneurysm. No diffusion restriction signals were observed in follow-up magnetic resonance imaging of the brain stem. Eleven weeks later, full recovery of left sixth nerve palsy was documented photographically. In conclusion, isolated contralateral abducens nerve palsy associated with ruptured VA aneurysm may develop due to direct nerve compression by displaced verterobasilar artery triggered by primary thick clot in the prepontine cistern.

    Purpose To evaluate the incidence and features of hypertropia in abducens nerve palsy. Methods The records of consecutive patients with unilateral, isolated, previously unoperated abducens nerve palsy were reviewed for binocular alignment on cover testing, Krimsky measurement, or Hess screen testing. Patients with associated cranial nerve palsy (including bilateral abducens palsies), orbital disease, myasthenia gravis, Horner syndrome, hemiplegia, cerebellar signs, arteritis, or previous strabismus surgery were excluded. Control subjects underwent complete examination to confirm normality. Results A total of 79 patients were included (40 males; mean age 49.2 years). Hypertropia in lateral or central gazes was present in 15 of 79 cases (19%) on alternate cover or Krimsky testing, in 32 of 56 cases (57%) on Hess screen testing, and absent in all 30 normal controls. Of cases with hypertropia, the mean of the greatest hypertropia in lateral or central gaze on was 5.0Δ ± 2.3Δ (standard deviation; range, 1Δ–8Δ) routine clinical examination, and 5.8Δ ± 4.2Δ (range, 2Δ–24Δ) on Hess screen testing. Of 39 cases with partial abducens palsy evaluated by Hess screen testing, the ipsilesional eye was hypertropic in 24 (61%) and hypotropic in 15 cases (39%). Conclusions Small-angle hypertropia is common in isolated, unilateral abducens and does not necessarily imply existence of multiple cranial neuropathies or skew deviation. PMID:24924275

    Carotid-cavernous fistulas (CCF) are abnormal communications between the internal carotid artery and the cavernous sinus. Traumatic carotid-cavernous fistulae are rare potential complications of craniofacial trauma. Typical findings of CCF are proptosis, chemosis, headache, oculomotor or abducens nerve palsy, trigeminal pain and pulsating bruit over the temporal skull and the bulb. CCF are reported very rarely in childhood. This report describes the clinical and radiological findings of a pediatric patient presented with CCF.

    2011-01-01

    Patients with anti-GQ1b antibody syndrome show various combinations of ophthalmoplegia, ataxia, areflexia, or altered sensorium as clinical features. We describe herein a unique case with unilateral abducens nerve palsy as an early feature of multiple mononeuropathy involving dysfunctions of the inferior dental plexus and the ulnar nerve, which was thought to be associated with anti-GQ1b antibody. A 27-year-old man presented with acute-onset diplopia. He subsequently experienced numbness not only in the right lower teeth and gums but also on the ulnar side of the left hand. Neurological examinations revealed dysfunctions of the right abducens nerve, the right inferior dental plexus, and the left ulnar nerve, suggesting multiple mononeuropathy. Serum anti-GQ1b antibody was positive. This is a rare case report of a patient with unilateral abducens nerve palsy as an early feature of multiple mononeuropathy associated with anti-GQ1b antibody. We suggest that anti-GQ1b antibody syndrome should be taken into consideration as a differential diagnosis of acute multiple mononeuropathy if ophthalmoplegia is present unilaterally. PMID:21490718

    2015-01-01

    Benign, isolated, recurrent sixth nerve palsy is rare in children. It may be associated with febrile viral illness and vaccination in exceptional circumstances although this is a diagnosis of exclusion. Here, we present the case of a 2-year-old Caucasian girl who developed recurrent 6th nerve palsy following vaccination with the measles-mumps-rubella (MMR) vaccine. No underlying pathology was identified following extensive investigations and followup. There is limited data available on the pathophysiology of vaccination-related nerve palsies. As with all previous reports of cranial nerve palsies following vaccination, there was complete resolution in this case. Long term followup with repeated physical examination and investigations is warranted to avoid missing severe pathology and operating unnecessarily. PMID:26257972

    A 4-year-old boy presented with right esotropia while receiving vincristine and dactinomycin for stage I Wilms’ tumour according to the National Wilms Tumour Study-5 protocol. On examination, he had isolated limitation of his right lateral gaze. CT of the brain and cerebrospinal fluid examination were normal. A nerve conduction velocity study which was performed on the peripheral nerves revealed predominant motor polyneuropathy compatible with axonal loss involving the upper limbs. The patient had received a cumulative vincristine dose of 17 mg/m2 before developing esotropia. Vincristine-induced abducens nerve mononeuropathy and subclinical motor polyneuropathy was suspected. Unilateral esotropia markedly improved after the discontinuation of vincristine and a short course of oral pyridoxine treatment. PMID:24966267

    2013-04-01

    We report the case of a 32-year-old woman with bilateral blowout fractures. She presented with diplopia showing impaired abduction of the left eye soon after trauma. No other orbito-ocular signs, such as exophthalmos, ptosis, or chemosis, were found. Orbital reconstruction was performed, but no improvement in her ophthalmoplegia was observed after surgery. A carotid angiography showed that she was suffering from a posteriorly draining carotid-cavernous sinus fistula with isolated abducens nerve palsy. Coil embolization was conducted under the consultation of a neurosurgeon, after which her ophthalmoplegia resolved fully. This is a rare case of posteriorly draining carotid-cavernous sinus fistula without classic orbito-ocular signs, the absence of which may cause diagnostic confusion. PMID:23415244

    The extraocular muscle palsies associated with herpes zoster ophthalmicus (HZO) are transient, self-limiting conditions, usually seen in elderly patients. There are different treatment recommendations for paralytic complications, but prognosis has generally reported to be favorable. A 75-year-old male patient presented with diplopia. Clinical history revealed left facial vesicular eruptions and pain treated by oral aciclovir 1 week following symptom onset. On examination, we observed cicatricial lesions with crusts involving left hemiface, a limitation in abduction of the left eye, and a superficial punctuate keratitis (SPK) with decreased visual acuity (4/10). Examination of the right eye was unremarkable. Hess screen test confirmed left six nerve palsy. PMID:24966563

    Traumatic brain injury (TBI) is less common in children than in adults. Posterior fossa lesions are even more uncommon, but, when present, are usually epidural hematomas. These lesions, even when small, may have a bad outcome because of the possibility of compression of the important structures that the infratentorial compartment contains, such as the brainstem and cranial nerves, and the constriction of the fourth ventricle, causing acute hydrocephalus. Although unusual, posterior fossa lesions are increasingly being diagnosed because of the better quality of and easier access to cranial tomography. In this paper, we report a case of a 12-year-old male patient who had suffered a TBI and presented with several pneumocephali, one of them in the retroclival region, causing a mass effect and then compression of the sixth cranial nerve which is the most susceptible to these injuries. We discuss these traumatic posterior fossa lesions, with an emphasis on retroclival pneumocephalus, not yet described in the literature in association with bilateral abducens palsy. In addition, we discuss associated lesions and the trauma mechanism. PMID:27193585

    We report a 74-year-old woman who presented with recurrent isolated abducens nerve paresis. Cranial magnetic resonance imaging revealed that the right abducens nerve was sandwiched between the right internal carotid artery and a persistent trigeminal artery (PTA) variant, which might have led to neurovascular compression of the abducens nerve, resulting in abducens nerve damage. Normal variants of PTA, which are cerebellar arteries originating from a precavernous portion of the internal carotid artery, must be carefully observed as such variants can potentially cause a neurovascular compression of the abducens nerve.

    Nervus abducens is a pure motor nerve located in the pons. It retracts the eyeball laterally by stimulating rectus lateralis muscle. In case of their paralysis, diplopia and restriction in the eye movements while looking sideways, are seen. Since the same signs are seen due to the muscle entrapment in blowout fractures, its differential diagnosis has importance in terms of the treatment protocol and avoiding unnecessary operations. In this article, we present a 22-year-old male patient who was referred to our department due to the prediagnosis of blowout fracture following maxillofacial trauma. However, he was diagnosed with abducens nerve paralysis after the consultations and analysis and his restriction of movement was resolved via systemic steroid treatment instead of unnecessary operation.

    After intravitreal ranibizumab injection for diabetic macular edema (DME) in a 55-year-old man, the patient was admitted to our ophthalmology clinic with the complaint of diplopia. Given the results of the patient's history, physical exam, and negative magnetic resonance imaging (MRI), we believed that the patient had a sixth nerve palsy related to ranibizumab injection. To the best of our knowledge, this is the first case with isolated abducens palsy after ranibizumab injection. PMID:26340018

    Although anomaly of the abducens nerve, including duplication, has been reported in anatomical papers, no radiological report exists regarding a duplicated abducens nerve observed on magnetic resonance (MR) imaging. We encountered a case of bilateral duplication of the abducens nerves, which was found incidentally on MR scans from an 11-year-old boy. He did not have any symptoms of eye movement related to abducens nerve abnormality; thus, the duplication was considered to be a normal variant in this patient. Radiologists should be aware that duplication of the abducens nerve may occur and can be diagnosed on MR, particularly when diagnosing symptomatic patients or as a preoperative assessment for microsurgery of the nerve.

    2016-01-01

    Background We have previously reported that the presence of the abducens nerve was variable in patients with type 3 Duane’s retraction syndrome (DRS), being present in 2 of 5 eyes (40%) and absent in 3 (60%) on magnetic resonance imaging (MRI). The previous study included only 5 eyes with unilateral DRS type 3. Objectives To supplement existing scarce pathologic information by evaluating the presence of the abducens nerve using high resolution thin-section MRI system in a larger number of patients with DRS type 3, thus to provide further insight into the pathogenesis of DRS. Data Extraction A retrospective review of medical records on ophthalmologic examination and high resolution thin-section MRI at the brainstem level and orbit was performed. A total of 31 patients who showed the typical signs of DRS type 3, including abduction and adduction deficit, globe retraction, narrowing of fissure on adduction and upshoot and/or downshoot, were included. The abducens nerve and any other extraocular muscle abnormalities discovered by MRI were noted. Results DRS was unilateral in 26 patients (84%) and bilateral in 5 patients (16%). Two out of 5 bilateral patients had DRS type 3 in the right eye and DRS type 1 in the left eye. Of the 34 affected orbits with DRS type 3 in 31 patients, the abducens nerve was absent or hypoplastic in 31 eyes (91%) and present in 3 eyes (9%). Patients with a present abducens nerve showed more limitation in adduction compared to patients with an absent abducens nerve (P = 0.030). Conclusions The abducens nerve is absent or hypoplastic in 91% of DRS type 3. Patients with a present abducens nerve showed more prominent limitation of adduction. As DRS type 3 partly share the same pathophysiology with type 1 and 2 DRS, the classification of DRS may have to be revised according to MRI findings. PMID:27352171

    The goal of this study was to determine the membranous protection of the abducens nerve in the petroclival region. The petroclival portion of the abducens nerve was studied in ten dissections from five cadaveric head specimens. One of the heads was used for histological sections. Four heads were injected with colored latex for microsurgical dissections. The histological sections were prepared from petroclival dura mater, embedded in paraffin blocks, stained, sectioned in the axial, coronal, and sagittal planes, and evaluated by light microscopy. The abducens nerve was covered by a dural sleeve and arachnoidal membrane during its course within the petroclival area. Following the petrous apex, the abducens nerve was fixed by a sympathetic plexus and connective tissue extensions to the lateral wall of the cavernous segment of the internal carotid artery and to the medial wall of Meckel's cave. Fibrous trabeculations inside the venous space were attached to the dural sleeve. The lateral clival artery accompanied the dural sleeve of the abducens nerve and supplied the petroclival dura mater. The arterioles accompanying the abducens nerve through the subarachnoid space supplied the nerve within the dural sleeve. The arachnoid membrane covered the abducens nerve within the dural sleeve to the petrous apex, and arachnoid granulations found on the dural sleeve protruded into the venous space. The extension of the arachnoid membrane to the petrous apex and the presence of arachnoid granulations on the dural sleeve suggest that the subarachnoid space continues in the dural sleeve.

    Objective: To study the clinical profile and outcome of surgery for injection nerve palsies. Materials and Methods: This is a retrospective study of patients with INP who were treated at our institute during May 2000 to May 2009. Clinical, electroneuromyography (ENMG), and operative findings were noted. Intraoperative nerve action potential monitoring was not used in any case. Outcome of patients who were followed was reviewed. Results: INP comprised 92 (11%) of 837 nerve injury patients. Seventy one patients were children less than 16 years. The nerves involved were sciatic in 80 patients, radial in 8, and others in four. Fifty seven patients had power, grade 0/5. ENMG studies revealed absent compound muscle action potential in 64 and absent sensory nerve action potential in 67 patients. Thirty nine (42.3%) of 92 patients underwent surgery. The mean duration since injury in these patients was 5.2 months (3 months to 11 months). All underwent neurolysis. Only 18 patients who underwent surgery had a follow up of more than 3 months. Ten (55.5%) patients had good or fair outcome after surgery. Except for grade of motor deficit prior to surgery, none of the variables were found to significantly affect the outcome. Conclusion: The outcome of INP is generally good and many patients recover spontaneously. The outcome of surgery is dependent on preoperative motor power. PMID:23546341

    2015-01-01

    We review ocular motor cranial nerve palsies in childhood and highlight many of the features that differentiate these from their occurrence in adulthood. The clinical characteristics of cranial nerve palsies in childhood are affected by the child's impressive ability to repair and regenerate after injury. Thus, aberrant regeneration is very common after congenital III palsy; Duane syndrome, the result of early repair after congenital VI palsy, is invariably associated with retraction of the globe in adduction related to the innervation of the lateral rectus by the III nerve causing co-contraction in adduction. Clinical features that may be of concern in adulthood may not be relevant in childhood; whereas the presence of mydriasis in III palsy suggests a compressive aetiology in adults, this is not the case in children. However, the frequency of associated CNS abnormalities in III palsy and the risk of tumour in VI palsy can be indications for early neuroimaging depending on presenting features elicited through a careful history and clinical examination. The latter should include the neighbouring cranial nerves. We discuss the impact of our evolving knowledge of congenital cranial dysinnervation syndromes on this field. PMID:25572578

    2016-07-01

    This study reports the first case of abducens nerve duplication along its entire intracranial course, ending within the orbit. A distinct abducens nerve duplication reaching the common tendinous ring (annulus of Zinn), as well as another split within the intraconal segment of the nerve have been revealed. Additionally, two groups (superior and inferior) of abducens nerve sub-branches to the lateral rectus muscle were visualised using Sihler's stain. The analysed anatomical variation has never been reported before and it seems to be in the middle of the spectrum between the cases of duplication occurring only within the intracranial segments of the abducens nerve found in the literature and those continuing throughout the whole course of the nerve. Abducens nerve duplication may be treated as a relic of early stages of ontogenesis. Such a variant might result from alternative developmental pathways in which axons of the abducens nerve, specific for a given segment of the lateral rectus muscle, run separately at some stage, instead of forming a single stem.

    Patients with rickettsial infection may present with encephalitis or meningitis but neurologic involvement is rare in murine typhus. Here, we report two patients with Rickettsia typhi meningitis who presented with cranial neuropathy, presumably caused by two distinct disease processes. Recognition of the disease manifestations is important because rickettsial infections are potentially associated with significant morbidity. Simple effective treatments are available. PMID:25548377

  14. Surgical management of third nerve palsy

    2016-01-01

    Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell's phenomenon, superior oblique (SO) overaction, and lateral rectus (LR) contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extraocular muscles are involved and therefore should be approached differently. Third nerve palsy can be congenital or acquired. The common causes of isolated third nerve palsy in children are congenital (43%), trauma (20%), inflammation (13%), aneurysm (7%), and ophthalmoplegic migraine. Whereas, in adult population, common etiologies are vasculopathic disorders (diabetes mellitus, hypertension), aneurysm, and trauma. Treatment can be both nonsurgical and surgical. As nonsurgical modalities are not of much help, surgery remains the main-stay of treatment. Surgical strategies are different for complete and partial third nerve palsy. Surgery for complete third nerve palsy may involve supra-maximal recession - resection of the recti. This may be combined with SO transposition and augmented by surgery on the other eye. For partial third nerve, palsy surgery is determined according to nature and extent of involvement of extraocular muscles. PMID:27433033

    Incomplete recovery of facial motor function continues to be long-term sequelae in some patients with Bell's palsy. The purpose of this study was to investigate the efficacy of transmastoid facial nerve decompression after steroid and antiviral treatment in patients with late stage Bell's palsy. Twelve patients underwent surgical decompression for Bell's palsy 21-70 days after onset, whereas 22 patients were followed up after steroid and antiviral therapy without decompression. Surgical criteria included greater than 90 % degeneration on electroneuronography and no voluntary electromyography potentials. This study was a retrospective study of electrodiagnostic data and medical chart review between 2006 and 2013. Recovery from facial palsy was assessed using the House-Brackmann grading system. Final recovery rate did not differ significantly in the two groups; however, all patients in the decompression group recovered to at least House-Brackmann grade III at final follow-up. Although postoperative hearing threshold was increased in both groups, there was no significant between group difference in hearing threshold. Transmastoid decompression of the facial nerve in patients with severe late stage Bell's palsy at risk for a poor facial nerve outcome reduced severe complications of facial palsy with minimal morbidity.

    A 52-year-old Caucasian man presented with sudden onset of difficulty in moving his tongue to the left with preceding left-sided headache with no neck pain. Earlier, he had self-limiting chest infection without rashes or tonsillar enlargement. His medical and surgical history was unremarkable with no recent trauma. Oral examination revealed difficulty in protruding his tongue to the left with muscle bulk loss and fasciculation on the same side, suggesting left hypoglossal nerve palsy. Examination of the rest of the cranial nerves and nervous system was normal. The patient's oropharyngeal and laryngeal examination was unremarkable with no cervical lymphadenopathy. He had normal laboratory investigations and cerebrospinal fluid examination. Extensive imaging of the head, neck and chest failed to reveal any pathology. Further review by an otorhinologist and rheumatologist ruled out any other underlying pathology. He made a good recovery without treatment. English literature search revealed very few cases of idiopathic, transient, unilateral hypoglossal nerve palsy. PMID:24969070

Past medical history relevant to the presenting complaint included: * Bell palsy diagnosed 20 years ago with no residual effect * biopsy confirmed benign parotid lump (diagnosed 3 years previously). Histopathology revealed a pleomorphic adenoma. Mrs PS declined surgical intervention at the time * chicken pox as a child * normal fasting blood glucose 1 month previously and no known immune compromise. Examination revealed yellow crusts and small vesicles on the external acoustic meatus (Figure 2). A 10 mm well defined firm and nontender nodule was palpable at the ramus of the mandible.

    Lemierre's syndrome is characterized by anaerobic septicemia, internal jugular vein thrombosis, and septic emboli associated with infections of the head and neck. We describe an unusual and clinically confusing case of a young woman with an acute paresis of the abducens nerve and partial paresis of the right oculomotor nerve. After an extensive imaging diagnostic procedure, we also documented a peritonsillar abscess and various types of thromboses in intracranial and extracranial veins. Furthermore, we found brain and lung abscesses, which led us to establish the diagnosis of Lemierre's syndrome. Despite intensive anti-coagulation and antibiotic therapy, the patient developed a mycotic aneurysm in the right internal carotid artery directly adjacent to the previously thrombosed cavernous sinus. In summary, we were able to confirm that Lemierre's syndrome may occur in conjunction with uncharacteristic symptoms. Due to the sometimes confusing clinical symptoms as well as clinical and radiological specialties, we had to work on an interdisciplinary basis to minimize the delay prior to establishing the diagnosis and therapy.

Our patient presented with clinical features of typical peripheral radial nerve palsy and a normal computed tomography scan of the head, which, without a detailed history and neurological examination, could have been easily misdiagnosed as a peripheral nerve lesion deferring further investigation for a stroke. We stress the importance of including cerebral infarction as a critical differential diagnosis in patients presenting with sensory-motor deficit in an isolated peripheral nerve pattern. A good history and physical exam can differentiate stroke from peripheral neuropathy as the cause of radial nerve palsy. PMID:27493976

    Legionnaires' disease is primarily a pneumonic process caused by Legionella pneumophilia, a gram-negative aerobic bacillus but also has multiple system involvement. The most common manifestation is encephalopathy suggesting a generalized brain dysfunction but focal neurological manifestations have been reported. We report a patient with Legionella pneumonia associated with cerebellar dysfunction and unilateral facial nerve weakness. 51-year-old previously healthy male presented with shortness of breath, cough, slurred speech, and unsteadiness on feet associated with malaise, fevers and myalgias. Patient's family reported facial asymmetry for 2 days. Patient had no significant medical history and was not on any medication. He denied smoking, alcohol or illicit drug use. Chest X-ray showed bilateral lower lobe infiltrates. Urinary antigen assay for Legionella pneumophilia serogroup 1 was positive. Patient was started on intravenous moxifloxacin. On day 5 the patient was discharged home and continued oral moxifloxacin for two weeks. After the two weeks, his respiratory symptoms, gait ataxia and dysarthria resolved. We report the first case of Legionnaires' disease with cerebellar dysfunction and seventh nerve palsy. Legionnaires' disease should be considered in patients with any neurological symptoms in the setting of pneumonia. Failure to recognize and treat the infection may lead to poor outcomes.

    The upper trunk of the brachial plexus is the most common area affected by neuralgic amyotrophy (NA), and paresis of the shoulder girdle muscle is the most prevalent manifestation. Posterior interosseous nerve palsy is a rare presentation in patients with NA. It results in dropped finger on the affected side and may be misdiagnosed as entrapment syndrome or compressive neuropathy. We report an unusual case of NA manifested as PIN palsy and suggest that knowledge of clinical NA phenotypes is crucial for early diagnosis of peripheral nerve palsies. PMID:26713154

    Six cases of clinically evident sciatic or peroneal nerve palsy occurred in a consecutive series of 380 total hip arthroplasties (THA). An additional eight cases of peroneal nerve palsy due to pressure from Thomas splint or tight bandages were seen. Factors apparently causing nerve palsy were significant lateralization and lengthening in four cases and dislocation of the hip in one case. The cases with neuroapraxia of the peroneal nerve were seen from the third to the fifth day of Thomas splint immobilization. EMG studies were conducted in all six group 1 patients; at the end of one year the results were good in two cases, fair in three cases, and poor in one case. The results suggest that limb lengthening should be limited to 4 cm to minimize this complication. It was also seen that patients with peroneal nerve palsy due to local compression do well, though some are bothered by mild residual dysesthesia over the dorsum of the foot. In contrast, patients with sciatic nerve palsy do not have such a good outlook. PMID:1345646

    We report an unusual case of spinal accessory nerve palsy sustained while transporting climbing gear. Spinal accessory nerve injury is commonly a result of iatrogenic surgical trauma during lymph node excision. This particular nerve is less frequently injured by blunt trauma. The case reported here results from compression of the spinal accessory nerve for a sustained period-that is, carrying a load over the shoulder using a single nylon rope for 2.5 hours. This highlights the importance of using proper load-carrying equipment to distribute weight over a greater surface area to avoid nerve compression in the posterior triangle of the neck. The signs and symptoms of spinal accessory nerve palsy and its etiology are discussed. This report is particularly relevant to individuals involved in mountaineering and rock climbing but can be extended to anyone carrying a load with a strap over one shoulder and across the body.

    Introduction The abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. The abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. This nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. It has been reported that 1% to 2.7% of all head injuries are followed by unilateral abducent palsy, but bilateral abducent nerve palsy is extremely rare. Case Presentation A 65-year-old woman presented to the emergency department following a motor vehicle accident. A neurological assessment showed the patient’s Glascow coma scale (GCS) to be 15. She complained of double vision, and we found lateral gaze palsy in both eyes. A hangman fracture type IIA (C2 fracture with posterior ligamentous C1 - C2 distraction) was found on the cervical CT scan. A three-month follow-up of the patient showed complete recovery of the abducent nerve. Conclusions Conservative treatment is usually recommended for traumatic bilateral abducent nerve palsy. Our patient recovered from this condition after three months without any remaining neurological deficit, a very rare outcome in a rare case. PMID:27218062

    Unilateral oculomotor nerve palsy is a rare and challenging condition for both emergency department (ED) physicians and neurosurgeons. In this report, we present you a case of head trauma with oculomotor nerve palsy whose initial neuroimaging findings were normal. A 50-year-old female presented to our ED due to head trauma secondary to fall from height. On her physical examination, ptosis, minimal lateral deviation, and dilated pupilla unresponsive to the light were determined in the left eye. A computed tomography and magnetic resonance imaging were performed and both were found to be normal. Patient was consulted with an ophthalmologist and any sign of direct trauma to the eye was not determined. Then, the patient was consulted with a neurosurgeon and hospitalized. In some rare instances, minor traumas to the head may result in isolated oculomotor nerve palsy without accompanying findings. Neurosurgeons and ED physicians must be careful about this rare condition. PMID:26396626

    BACKGROUND The aim of this study was to analyze the causes that lead to secondary damage of the radial nerve and to discuss the results of reconstructive treatment. MATERIAL AND METHODS The study group consisted of 33 patients treated for radial nerve palsy after humeral fractures. Patients were diagnosed based on clinical examinations, ultrasonography, electromyography, or nerve conduction velocity. During each operation, the location and type of nerve damage were analyzed. During the reconstructive treatment, neurolysis, direct neurorrhaphy, or reconstruction with a sural nerve graft was used. The outcomes were evaluated using the Medical Research Council (MRC) scales and the quick DASH score. RESULTS Secondary radial nerve palsy occurs after open reduction and internal fixation (ORIF) by plate, as well as by closed reduction and internal fixation (CRIF) by nail. In the case of ORIF, it most often occurs when the lateral approach is used, as in the case of CRIF with an insertion interlocking screws. The results of the surgical treatment were statistically significant and depended on the time between nerve injury and revision (reconstruction) surgery, type of damage to the radial nerve, surgery treatment, and type of fixation. Treatment results were not statistically significant, depending on the type of fracture or location of the nerve injury. CONCLUSIONS The potential risk of radial nerve neurotmesis justifies an operative intervention to treat neurological complications after a humeral fracture. Adequate surgical treatment in many of these cases allows for functional recovery of the radial nerve. PMID:26895570

    Kawasaki disease is rarely complicated by cranial nerve VII palsy. This report describes a 15-month-old female presenting with 3 days of fever, irritability, and rash who was subsequently diagnosed with Kawasaki disease and treated with intravenous immunoglobulin. She was found to have mild coronary artery ectasia and developed an acute, transient, left-sided facial palsy on the sixth day of illness. Repeat echocardiography demonstrated worsening aneurysm and intravenous methylprednisolone was added to her treatment regimen. At 1 and 3 months post-discharge, echocardiography demonstrated resolution of her coronary aneurysm. This case makes 41 total described in the literature. Patients tend to be under 12-months-old and there is a higher association with coronary artery aneurysm in such patients compared to those without facial palsy who never even received treatment. Kawasaki disease associated with facial palsy may indicate increased inflammatory burden and patients may require additional anti-inflammatory agents and more vigilant echocardiography.

    Facial nerve palsy is associated with significant morbidity and can have different etiologies. The most common causes are Bell’s palsy, Ramsay–Hunt syndrome and trauma, including surgical trauma. Incidence varies between 17 and 35 cases per 100,000. Initial evaluation should include accurate clinical history, followed by a comprehensive investigation of the head and neck, including ophthalmological, otological, oral and neurological examination, to exclude secondary causes. Routine laboratory testing and diagnostic imaging is not indicated in patients with new-onset Bell’s palsy, but should be performed in patients with risk factors, atypical cases or in any case without resolution within 4 months. Many factors are involved in determining the appropriate treatment of these patients: the underlying cause, expected duration of nerve dysfunction, anatomical manifestations, severity of symptoms and objective clinical findings. Systemic steroids should be offered to patients with new-onset Bell’s palsy to increase the chance of facial nerve recovery and reduce synkinesis. Ophthalmologists play a pivotal role in the multidisciplinary team involved in the evaluation and rehabilitation of these patients. In the acute phase, the main priority should be to ensure adequate corneal protection. Treatment depends on the degree of nerve lesion and on the risk of the corneal damage based on the amount of lagophthalmos, the quality of Bell’s phenomenon, the presence or absence of corneal sensitivity and the degree of lid retraction. The main therapy is intensive lubrication. Other treatments include: taping the eyelid overnight, botulinum toxin injection, tarsorrhaphy, eyelid weight implants, scleral contact lenses and palpebral spring. Once the cornea is protected, longer term planning for eyelid and facial rehabilitation may take place. Spontaneous complete recovery of Bell’s palsy occurs in up to 70% of cases. Long-term complications include aberrant regeneration

    Oculomotor nerve palsy frequently occurs because of external compression by an internal carotid-posterior communicating artery aneurysm and diabetes mellitus. In addition, pontine infarction, cavernous sinus tumors, demyelinating disease, and autoimmune disorder are well-known causes of oculomotor nerve palsy. However, cases of complete oculomotor nerve palsy by neurovascular conflicts presented with a sudden onset of clinical symptoms are extremely rare. We experienced a rare case of complete oculomotor nerve palsy because of direct vascular compression of the oculomotor nerve by the posterior cerebral artery. PMID:25939862

    Guillain-Barre syndrome (GBS) is an acquired immune-mediated inflammatory disorder of the peripheral nervous system. GBS is also called acute idiopathic polyradiculoneuritis. Cranial nerves are affected in over 50% of all cases, with the facial nerves being affected the most. Otherwise, oculomotor nerves affection is rare and might occur in about 10% of cases. In this case report we present 61 years old female with GBS (acute motor and sensory axonal neuropathy subtype) associated with bilateral oculomotor nerve palsy. At the admittance in the neurological status were flaccid paraplegia, tendon reflexes absent at legs and reduced at arms, sensory disturbances in a distal (stocking-glove) distribution and bilateral ptosis. The disease was diagnosed on clinical features, nerve conduction velocity test (NCV), electromyogram (EMG) and cerebrospinal fluid (CSF) tests. After treatment with intravenous immunoglobulins and physical treatment the patient improved. She was able to walk by her own, mild semiptosis remained and she had no paresthesia. PMID:18669237

Conclusions Most of the times, measles, mumps and rubella cause mild illness and discomfort; but can also have serious or fatal sequelae. MMR vaccination has been proved to be safe and to reduce significantly the number of reported infections due to these viruses. However, significant adverse events can occur and paediatricians and public health operators should be aware of this aspect. PMID:20831779

    Introduction: Recurrent oculomotor nerve palsies are extremely rare clinical conditions. Case report: Here, we report on a unique case of a short-lasting recurrent unilateral incomplete external and complete internal oculomotor nerve palsy. The episodic palsies were probably caused by an ipsilateral mesencephalic metastasis of a breast carcinoma and occurred after successful brain radiation therapy. Discussion: While the pathogenic mechanism remains unclear, the recurrent sudden onset and disappearance of the palsies and their decreasing frequency after antiepileptic treatment suggest the occurrence of epilepsy-like brainstem seizures. A review of case reports of spontaneous reversible oculomotor nerve palsies is presented. PMID:25104947

    We report the case of a 43-year-old gentleman who presented with an isolated left sixth nerve palsy in association with postural headache. Magnetic resonance imaging showed dural enhancement with downward displacement of the brainstem. This, in association with the signs, symptoms and findings on lumbar puncture, confirmed the diagnosis of spontaneous intracranial hypotension. Treatment was successful with epidural blood patching. The case is discussed and the relevant literature reviewed. PMID:17038044

    We present a case of posterior interosseous nerve palsy after bowel surgery associated with intramuscular myxoma of the supinator muscle. The initial symptoms of swelling of the forearm made it difficult to distinguish the condition from extravasations after intravenous cannulation. The diagnosis was finally established with nerve conduction studies and MRI 3 months after symptom onset. The patient underwent surgery for removal of the tumour and decompression of the posterior interosseous nerve. The histological examination identified the tumour as intramuscular myxoma and the patient made a full recovery with no recurrence of the lesion until present. Every swelling on the forearm causing neurological disorders is tumour suspected and should be examined clinically as well as electrophysically and radiographically. Early surgery and nerve decompression should follow immediately after the diagnosis. In case of intramuscular myxoma, good recovery of function after surgery with low recurrence risk may be expected.

    Although the incidence of sciatic nerve palsy following total hip arthroplasty is low, this complication can cause devastating permanent nerve palsy. The authors experienced a case of sciatic nerve palsy caused by ruptured and contracted external rotator muscles following total hip arthroplasty in a patient suffering from osteonecrosis of the femoral head. We report this unusual case of sciatic nerve palsy with a review of the literature.

    A 68-year-old man had an unremitting left sixth cranial nerve palsy immediately after completing a long bicycle trip. High-resolution (3 Tesla) magnetic resonance imaging disclosed a dolichoectatic vertebral artery that compressed the left sixth cranial nerve against the belly of the pons at its root exit zone. It was postulated that increased blood flow in the vessel during the unusually prolonged aerobic exercise precipitated the palsy. Compressive palsies of cranial nerves caused by a dolichoectatic basilar artery have often been documented; compressive palsy caused by a dolichoectatic vertebral artery is less well-recognized.

    Spontaneous dissection of the extracranial internal carotid artery is a well recognized cause of headache and juvenile stroke; lower cranial nerve palsy as a complication of dissection is rare. We report the case of a female patient with bilateral dissecting aneurysm of the internal carotid artery, associated with unilateral cranial nerve XII palsy and oculosympathetic palsy. Neuroradiological findings, in particular those obtained by Magnetic Resonance imaging, allow the identification of the dissecting pathology and the correlation of the aneurysmal formation with nerve palsy.

    2010-01-01

    Introduction Isolated spinal accessory nerve dysfunction has a major detrimental impact on the functional performance of the shoulder girdle, and is a well-documented complication of surgical procedures in the posterior triangle of the neck. To the best of our knowledge, the natural course and the most effective way of handling spontaneous spinal accessory nerve palsy has been described in only a few instances in the literature. Case presentation We report the case of a 36-year-old Caucasian, Greek man with spontaneous unilateral trapezius palsy with an insidious course. To the best of our knowledge, few such cases have been documented in the literature. The unusual clinical presentation and functional performance mismatch with the imaging findings were also observed. Our patient showed a deterioration that was different from the usual course of this pathology, with an early onset of irreversible trapezius muscle dysfunction two months after the first clinical signs started to manifest. A surgical reconstruction was proposed as the most efficient treatment, but our patient declined this. Although he failed to recover fully after conservative treatment for eight months, he regained moderate function and is currently virtually pain-free. Conclusion Clinicians have to be aware that due to anatomical variation and the potential for compensation by the levator scapulae, the clinical consequences of any injury to the spinal accessory nerve may vary.

    Occipital nerve blocks are commonly performed to treat a variety of headache syndromes and are generally believed to be safe and well tolerated. We report the case of an otherwise healthy 24-year-old woman with left side-locked occipital, parietal, and temporal pain who was diagnosed with probable occipital neuralgia. She developed complete left facial nerve palsy within minutes of blockade of the left greater and lesser occipital nerves with a solution of bupivicaine and triamcinolone. Magnetic resonance imaging of the brain with gadolinium contrast showed no abnormalities, and symptoms had completely resolved 4-5 hours later. Unintended spread of the anesthetic solution along tissue planes seems the most likely explanation for this adverse event. An aberrant course of the facial nerve or connections between the facial and occipital nerves also might have played a role, along with the patient's prone position and the use of a relatively large injection volume of a potent anesthetic. Clinicians should be aware that temporary facial nerve palsy is a possible complication of occipital nerve block. PMID:24913733

    Bilateral hip dislocation is a rare condition. We report a case of traumatic bilateral hip dislocation and unilateral sciatic nerve palsy in a young woman with known idiopathic scoliosis. With prompt reduction of the dislocated hips, there was reasonable neurological recovery. There was no avascular necrosis of the femoral head or post-traumatic arthritis up to 3-year follow-up. The gender difference in incidence, as well as the predisposition of hip dislocation in scoliosis is discussed. In our case, the decreased femoral anteversion was the culprit. PMID:25809426

    We examined a 34-year-old man who complained of decreased visual acuity in the right eye when exposed to cold environmental temperatures. Although examination at room temperature was unremarkable, he developed prominent unilateral corneal edema of the right eye when placed in a cold room at 4 C. Corneal thickness increased from 525 to 789 microns in the affected eye. Further examination disclosed a right-sided trigeminal nerve palsy. He was eventually found to have a 3 X 2-cm tentorial ridge meningioma on the right.

    The head and neck is anatomically complex, and several nerves are at risk during orthognathic operations. Some injuries to nerves are reported more commonly than others. To find out what consultant surgeons tell their patients about the prevalence of common nerve injuries before orthognathic operations, we did a postal survey of fellows of the British Association of Oral and Maxillofacial Surgeons (BAOMS). We also reviewed published papers to find out the reported incidence of injuries to cranial motor nerves during orthognathic operations. Only injuries to the facial nerve were commonly reported, and we found only case reports about injuries to the oculomotor, abducens, and trochlear nerves. The risk of temporary facial nerve palsy reported was 0.30/100 nerves (95% CI 0.23 to 0.50) and permanent facial nerve palsy was 0.06/100 nerves (95% CI 0.02 to 0.15). PMID:26935213

  15. Reaching the Limit of the Oculomotor Plant: 3D Kinematics after Abducens Nerve Stimulation during the Torsional Vestibulo-Ocular Reflex

    2012-01-01

    Accumulating evidence shows that the oculomotor plant is capable of implementing aspects of three-dimensional kinematics such as Listing's law and the half-angle rule. But these studies have only examined the eye under static conditions or with movements that normally obey these rules (e.g., saccades and pursuit). Here we test the capability of the oculomotor plant to rearrange itself as necessary for non-half-angle behavior. Three monkeys (Macaca mulatta) fixated five vertically displaced targets along the midsagittal plane while sitting on a motion platform that rotated sinusoidally about the naso-occipital axis. This activated the torsional, rotational vestibulo-ocular reflex, which exhibits a zero-angle or negative-angle rule (depending on the visual stimulus). On random sinusoidal cycles, we stimulated the abducens nerve and observed the resultant eye movements. If the plant has rearranged itself to implement this non-half-angle behavior, then stimulation should reveal this behavior. On the other hand, if the plant is only capable of half-angle behavior, then stimulation should reveal a half-angle rule. We find the latter to be true and therefore additional neural signals are likely necessary to implement non-half-angle behavior. PMID:22993439

    INTRODUCTION A facial nerve palsy combined with parotid enlargement usually suggests malignancy. It is highly unusual for facial nerve palsy to result from a benign situation such as inflammation or infection of the gland. PRESENTATION OF CASE We present a rare case of facial nerve palsy due to parotid abscess. DISCUSSION A literature search retrieved thirty-two cases of facial nerve palsy due to benign parotid lesions since 1969. Only nine reported the presence of a parotid abscess. The etiology of paralysis remains unknown although certain factors such as the virulence of the offending organisms or perineuritis, have been suggested. Best diagnostic evaluation and management are discussed. CONCLUSION In clinical practice, exclusion of malignancy is mandatory, as it represents the most common cause of facial palsy in the presence of a parotid lump. PMID:24096025

    Facial nerve palsy induces a weakness or loss of facial expression through damage of the facial nerve. A quantitative and reliable assessment system for facial nerve palsy is required for both patients and clinicians. In this study, we propose a rapid and portable smartphone-based automatic diagnosis system that discriminates facial nerve palsy from normal subjects. Facial landmarks are localized and tracked by an incremental parallel cascade of the linear regression method. An asymmetry index is computed using the displacement ratio between the left and right side of the forehead and mouth regions during three motions: resting, raising eye-brow and smiling. To classify facial nerve palsy, we used Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM), and Leave-one-out Cross Validation (LOOCV) with 36 subjects. The classification accuracy rate was 88.9%. PMID:26506352

    Hereditary neuropathy with liability to pressure palsy (HNPP) is characterized by recurrent focal neuropathies, which usually become symptomatic in the second or third decade of life. However, clinical phenotypic heterogeneity among patients with HNPP has recently been reported. Certain patients show polyneuropathy-type diffuse nerve injuries, whereas others remain asymptomatic at older ages. We present two cases of elderly-onset bilateral peroneal nerve palsies with diffuse muscle weakness in the lower limbs and glove-and-stocking type sensory disturbance. Both patients were diagnosed with HNPP by genetic analyses that detected deletions of chromosome 17p11.2 in peripheral myelin protein 22 genes. Their clinical courses suggested that the Japanese sitting style termed 'seiza', a way of sitting on the floor with the lower legs crossed under the thighs, was a precipitating factor for the bilateral peroneal nerve palsies.

    Hofer, Jennifer E; Scavone, Barbara M

    2015-03-01

    In this article, we provide a literature review of cranial nerve (CN) VI injury after dural-arachnoid puncture. CN VI injury is rare and ranges in severity from diplopia to complete lateral rectus palsy with deviated gaze. The proposed mechanism of injury is cerebrospinal fluid leakage causing intracranial hypotension and downward displacement of the brainstem. This results in traction on CN VI leading to stretch and neural demyelination. Symptoms may present 1 day to 3 weeks after dural-arachnoid puncture and typically are associated with a postdural puncture (spinal) headache. Resolution of symptoms may take weeks to months. Use of small-gauge, noncutting spinal needles may decrease the risk of intracranial hypotension and subsequent CN VI injury. When ocular symptoms are present, early administration of an epidural blood patch may decrease morbidity or prevent progression of ocular symptoms. PMID:25695579

    We report a case of symptomatic ecchordosis physaliphora (EP) in a 34-year-old woman who presented with progressive diplopia due to palsy of the left sixth cranial nerve. Repeated magnetic resonance imaging (MRI) disclosed typical characteristics of a congenital EP lesion with compression of the left abducens nerve presumably because of a secondary herniation of the arachnoid mater. We performed an augmenting combined recess resect procedure on the left eye. No progression of the lesion was observed over a period of 5 years. For differential diagnostics an EP has to be distinguished from skull base tumors, such as chordoma and chondrosarcoma. PMID:26502168

    Posterior communicating artery (PCOM) aneurysms may cause third nerve palsies. The optimal treatment with clipping versus coiling remains controversial. Here we report on two cases of resolution of third nerve palsy after flow diversion embolization of large and giant PCOM aneurysms without adjuvant coil placement. The resolution of third nerve palsy was not preceded by significant shrinkage of the aneurysmal sac on MRI. However, one patient showed resolution of T2-weighted signal abnormalities in the midbrain and mesial temporal lobe despite a similar size of the aneurysm. Therefore, flow diversion embolization of a PCOM aneurysm may resolve oculomotor nerve palsies through decreasing arterial pulsations against the nerve or midbrain. PMID:27183957

    Abstract Objective: To present the case of a National Collegiate Athletic Association Division I men's lacrosse athlete with fourth cranial nerve injury as the result of a minor traumatic blow. Background: The athlete was struck on the right side of his head during a lacrosse game. On-field evaluation revealed no cervical spine involvement or loss of consciousness. He complained of headache and dizziness, with delayed reports of visual disturbance. Sideline visual acuity and cranial nerve screenings appeared within normal limits. Consultation with the team physician indicated that immediate referral to the emergency department was unnecessary. Differential Diagnosis: Concussion, third cranial nerve palsy, fourth cranial nerve palsy. Treatment: The certified athletic trainer safely removed the athlete from the playing field and monitored him on the sideline. After being seen by the team physician, the patient was referred to a neurologist, ophthalmologist, and finally a neuro-ophthalmologist before a definitive diagnosis was made. The palsy did not necessitate surgical intervention, resolving with conservative treatment. The athlete was able to return to full athletic ability at his preinjury level by 8 months postinjury. Uniqueness: Superior oblique palsy as the result of fourth cranial nerve injury is the most frequent isolated cranial nerve palsy; however, these palsies are often underdiagnosed by health professionals. Such palsies are uncommon within the athletic realm, making timely diagnosis even less likely. Conclusions: Cranial nerve palsy may present very subtly in patients. Therefore, on-field health care providers should be aware of the descriptions and types of compensations that signal nerve injury. PMID:20617917

    In selected cases acquired peroneal palsy is caused by intraneural ganglia. In contrast to the much more frequent "loco typico" lesion which is caused by external pressure, intraneural ganglia can be treated by microscopic nerve surgery as part of primary treatment strategy. A careful clinical history as well as a profound clinical and electrophysiological examination is required to disclose unusual findings. These are common in non-typical peroneal palsy. In this situation high resolution nerve sonography is a fast and sensitive method to detect intraneural ganglia. We report a case series of three patients with peroneal palsy caused by intraneural ganglia and give a review of the literature. PMID:25446682

Again, tuberculoma can arise following development of Cushing syndrome after prolonged intake of steroids due to origin of immunosuppressed state. Thus exogenous steroid administration leading to iatrogenic Cushing Syndrome which again causing tuberculoma, with facial nerve palsy developing as a manifestation of tuberculoma is not unnatural but definitely a unique scenario. The author reports an interesting case where a patient developed left sided facial palsy following development of intracranial tuberculoma from iatrogenic Cushing syndrome after longterm intake of Dexamethasone as a treatment for low back pain.

    Oculomotor nerve palsy can be due to varied causes that include diabetic neuropathy, myasthenia gravis, brainstem infarction, demyelinating conditions, and cerebral aneurysms. Among the aneurysmal causes of oculomotor nerve palsy, aneurysm of the posterior communicating artery has been observed to be the most common. Pupillary dysfunction is considered to be an important feature of aneurysmal oculomotor nerve paresis. A case of a 7-year-old boy with partial oculomotor nerve palsy with pupillary sparing is being reported here, the etiology of which is tortuous and ectatic distal internal carotid artery. This is a rare cause of oculomotor nerve paresis and to the best of our knowledge has not yet been reported in children. Ischemia rather than compression seems to be the most plausible cause in this case. PMID:27606031

    Reconstruction for trigeminal nerve II palsy is challenging. Cross-face nerve transfer from the contralateral trigeminal nerve facilitates this reconstruction. However, the microanatomy and techniques required for nerve sutures cause problems for many surgeons. Following the recent development of supramicrosurgical techniques appropriate for the microanatomy of peripheral nerves, a new method of intraoral "cross-face nerve transfer" was successfully used for repairing trigeminal nerve II palsy. Two cases of trigeminal nerve II palsy were repaired with contralateral trigeminal nerve transfer without any nerve graft. Affected upper labial sensory recovery was 1.65 to 2.44 (Semmes-Weinstein values) and 15 to 30 mm (moving 2-point discriminations) at 1 to 1 1/2 years after surgery. The advantages of this method are excellent nerve regeneration and the lack of donor site morbidity. It is a brief and simple operation in comparison to free nerve grafts. The disadvantage is a need for a supramicrosurgical technique, using a needle less than 80 microm wide. PMID:19934846

    Purpose: The purpose of this study was to investigate the effect of an innovative exhibitory eye model simulation in a physical examination laboratory format on explaining Listing's Law concerning the individual extraocular muscle action and the rationale for cranial nerve testing. Methods: Participants were 71 volunteers in the third quarter of a chiropractic training program. The study involved a specially designed eyeball model used to explain the movements of individual extraocular muscles based on Listing's law and their cranial innervations in conjunction with the physical examination. Pre- and post-written tests were used to assess participants' understanding of the subjects taught. The test results were compared with those of nonparticipants who also took the same pre- and posttests. Results: An independent samples t-test of the posttest showed a significant difference between the groups. The study group students achieved higher scores than their counterparts in the control group. Conclusion: Using an innovative approach to explain Listing's law and rationale for cranial nerve tests can improve physical examination skill and help produce more effective written test results.

Herein we present a patient with Hansen disease (BL) with type I reaction who developed isolated involvement of the sixth cranial nerve leading to lateral rectus muscle palsy. He responded to timely anti-reactional therapy and it produced a good response. Careful observation of patients with lepra reaction is needed to avoid damage to important organs. PMID:22948066

    Oculomotor nerve palsy is a rare finding in children and, when reported, is most frequently either congenital or acquired from postnatal trauma, infection, aneurysm, or migraine. Intracranial lipomas also represent an uncommon finding in children, and although their development is not completely understood, they are now thought to be congenital in nature. Here, we describe the case of a 23-month-old boy presenting to the emergency department with left-sided, complete, pupil-involving oculomotor nerve palsy. On magnetic resonance imaging, he was found to have an intracranial lipoma of the left interpeduncular fossa. The patient had gradual and spontaneous improvement of symptoms, with complete resolution reported at the 4-month follow-up visit. However, a second magnetic resonance image at 6 months revealed that the lipoma did not change in size. To our knowledge, intracranial lipomas have been previously reported as a possible cause of partial oculomotor nerve palsy in only one adult and have never been reported in a child. In addition, we did not find any reports of intracranial lipomas as a cause of complete, pupil-involving oculomotor palsy, although they are known to cause other cranial nerve pathology. We conclude that intracranial lipomas, although rare, should be considered in the differential diagnosis for oculomotor nerve palsy in children. Further investigation is needed to determine the true incidence of this association. PMID:22307184

    Bilateral facial nerve palsy is an exceedingly rare condition and presents a diagnostic challenge. Bilateral facial nerve palsy may result from cranial trauma, congenital abnormalities, inflammation, infiltration, or infection, but is rarely associated with syphilis. Here, we report a case of syphilis in which bilateral facial nerve palsy was the only initial symptom. A 22-year-old man presented at our emergency department with isolated bilateral facial nerve palsy. Results for initial serum and cerebrospinal fluid examinations were normal, including the rapid plasma reagin titer. One week later, the patient developed rashes on the torso, palms, and soles. At this time, a high serum rapid plasma reagin titer was detected, and the Treponema pallidum particle agglutination test was positive. Once the tests were confirmed, the patient admitted to a history of unprotected sexual behavior. Penicillin G treatment was effective, and a 3-month follow-up examination demonstrated a complete recovery. We recommend that syphilis be considered when diagnosing sexually experienced young men presenting with bilateral facial nerve palsy, even in the absence of skin manifestations. Failure to recognize facial signs of syphilis could result in inappropriate management, affecting the patient's clinical outcome. PMID:26166431

    Mononeuropathy after surgery may occur and hereditary neuropathy with liability to pressure palsies is a possible pathological condition related to paresis after hip surgery. We present a case of 66-year-old man presenting severe weakness at inferior limb muscles after hip prosthesis revision. Clinic and electrophysiology showed severe right fibular nerve damage and ultrasound found a marked enlargement of the same nerve, associated with focal enlargements in other nerves. A diagnosis of hereditary neuropathy with liability to pressure palsies was suspected and confirmed by genetic test. The patient gradually recovered returning to a normal daily active life. Ultrasound was crucial for diagnosis. The suspicion and diagnosis of latent neuropathy, which can occur after surgical intervention, may lead to a better understand of the risks of the surgery, specific for the patient, and avoid the wrong attribution to surgical malpractice.

    We describe isolated cranial nerve-III palsy as a rare clinical finding in a patient with perimesencephalic subarachnoid hemorrhage. In this unusual case, the patient presented with complete cranial nerve-III palsy including ptosis and pupillary involvement. Initial studies revealed subarachnoid hemorrhage in the perimesencephalic, prepontine, and interpeduncular cisterns. Angiographic studies were negative for an intracranial aneurysm. The patient's neurological deficits improved with no residual deficits on follow-up several months after initial presentation. Our case report supports the notion that patients with perimesencephalic subarachnoid hemorrhage have an excellent prognosis. Our report further adds a case of isolated cranial nerve-III palsy as a rare initial presentation of this type of bleeding, adding to the limited body of the literature. PMID:26949557

We report a case of a 60-year-old woman who developed sudden onset right-sided pupil sparing oculomotor nerve palsy along with a tender swelling at right sternoclavicular joint. Cranial and orbital magnetic resonance imaging and cerebrospinal fluid examination demonstrated no abnormalities. Immunological investigations and histopathological analysis of sternoclavicular joint swelling confirmed the diagnosis of IgG type multiple myeloma. After confirmation of diagnosis we started her with appropriate chemotherapy, after which the palsy resolved within one month. The cause of the palsy was probably due to nerve ischemia due to hyper viscosity of the serum. PMID:27437257

  4. Cause of long thoracic nerve palsy: a possible dynamic fascial sling cause.

    Long thoracic nerve palsy can result from sudden or repetitive external biomechanical forces. This investigation describes a possible dynamic cause from internal forces. Six fresh cadaveric shoulders (3 female, 3 male, 4 left, 2 right) with full range of motion were systematically dissected to evaluate the anatomic course of the long thoracic nerve. In all specimens a tight fascial band of tissue arose from the inferior aspect of the brachial plexus, extended just superior to the middle scalene muscle insertion on the first rib, and presented a digitation that extended to the proximal aspect of the serratus anterior muscle. With progressive manual abduction and external rotation, the long thoracic nerve was found to "bow-string" across the fascial band. Medial and upward migration of the superior most aspect of the scapula was found to further compress the long thoracic nerve. Previous investigations have reported that nerves tolerate a 10% increase in their resting length before a stretch-induced neuropraxia develops. Previous studies postulated that long thoracic nerve palsy resulted from the tethering effect of the scalenus medius muscle as it actively or passively compressed the nerve; however, similar neuromuscular relationships occur in many other anatomic sites without ill effect. We propose that the cause of long thoracic nerve palsy may be this "bow-stringing" phenomenon of the nerve across this tight fascial band. This condition may be further exacerbated with medial and upward migration of the superior aspect of the scapula as is commonly seen with scapulothoracic dyskinesia and fatigue of the scapular stabilizers. Rehabilitation for long thoracic nerve palsy may therefore benefit from special attention to scapulothoracic muscle stabilization. PMID:10717860

    Although glufosinate ammonium herbicides are considered safe when used properly, ingestion of the undiluted form can cause grave outcomes. Recently, we treated a 34-yr-old man who ingested glufosinate ammonium herbicide. In the course of treatment, the patient developed apnea, mental deterioration, and sixth cranial nerve palsy; he has since been discharged with full recovery after intensive care. This case report describes the clinical features of glufosinate intoxication with a focus on sixth cranial nerve palsy. Our observation suggests that neurologic manifestations after ingestion of a "low-grade toxicity herbicide" are variable and more complex than that was previously considered. PMID:24265537

    Bell's palsy is a common neurological problem causing considerable loss of self-esteem among patients. A prospective observational study was conducted to determine the short-term outcome of Bell's palsy at 1 month and 2 months after the onset and the relationship between these outcomes with facial nerve degeneration. We also determined if gender, age, diabetes, systolic and diastolic blood pressure influence the severity of facial nerve degeneration and the clinical outcome at 2 months after the onset. After clinically grading the newly diagnosed unilateral Bell's palsy patients using the House-Brackmann facial nerve grading system, nerve conduction studies of the facial nerve were done to determine the severity of facial nerve degeneration. The recovery of the facial paralysis was clinically graded again at the end of 1 month and 2 months from the onset. A total of 37 patients were recruited. There was a strong positive correlation between facial nerve degeneration and the clinical outcome of Bell's palsy at 1 month (r = 0.794; p < 0.0005) and 2 months (r = 0.732; p < 0.0005) after the onset. There was no significant correlation between either the facial nerve degeneration or the clinical outcome at 2 months with the patients' age (p = 0.288 and p = 0.799 respectively), systolic blood pressure (p = 0.425 and p = 0.933 respectively) or diastolic blood pressure (p = 0.243 and p = 0.579 respectively). Neither the severity of facial nerve degeneration nor the clinical outcome at 2 months were significantly different between male and female patients (p = 0.460 and p = 0.725 respectively) or diabetic and non-diabetic patients (p = 0.655 and p = 0.655 respectively).

    Facial muscles are of major importance in human craniofacial growth and development. The purpose of our study was to investigate whether congenital facial nerve palsy influences craniofacial growth in craniofacial microsomia. Fifty-one patients with unilateral craniofacial microsomia and no history of craniofacial skeletal surgery whose radiographs were taken after craniofacial growth was complete were included in this study. These patients were divided into groups in which the facial nerve was involved or uninvolved. The authors evaluated a total of seven measurement items to analyze the midface and mandibular asymmetry. Twenty patients had facial nerve involvement, and 31 had no involvement. None of the measurement items revealed any significant differences between the facial nerve-involved group and the uninvolved group within the same modified Pruzansky grade. There was no correlation between the type of facial nerve involvement and the measurement items. In relationships among the measurement items within each group, maxillary asymmetry was indirectly correlated with mandibular asymmetry or midline deviation through the occlusal plane angle in the uninvolved groups. However, in the facial nerve-involved group, the relationships disappeared. When the correlations in the facial nerve-involved group were compared with those of the uninvolved group, the relationships in the uninvolved group appeared more significant than in the facial nerve-involved group. The loss of relationships between the upper and lower jaw in the facial nerve-involved group might have been caused by subtle changes, which occur in midfacial bones and in the mandible due to facial nerve palsy. The main limitation of our study is that aside from facial nerve palsy, craniofacial microsomia has many factors that can influence craniofacial growth, such as hypoplasia of the mandibular condyle and soft tissue deficiencies.

We report the case of a 57-year-old patient admitted with foot drop, due to an extraneural ganglion of the upper tibiofibular syndesmosis, compressing the deep branch of the peroneal nerve. Although there have been many previous reports of intraneural ganglion involvement with the lower limb nerves, to our knowledge, this is the second reported occurrence of an extraneural ganglion distinctly localized to the upper tibiofibular syndesmosis and palsying deep peroneal nerve. The diagnosis was made preoperatively using MRI. The common peroneal nerve and its branches were recognized and traced to its bifurcation during the operation, and the ganglion cyst was removed. Two months after surgery, the patient was pain-free and asymptomatic except for cutaneous anesthesia in the distribution of the deep peroneal nerve. PMID:25632363

    Neurovascular compression is assumed to cause symptoms like trigeminal neuralgia, hemifacial spasm and vestibular paroxysmia. We present a patient with recurrent episodes of transient dysarthria due to isolated right hypoglossal nerve (HN) palsy. We describe the first case of a calcified persistent hypoglossal artery (PHA) as the putative cause of a hypoglossal neurovascular compression syndrome. Our patient received a daily low-dose medication of carbamazepine resulting in complete relief of symptoms. In conclusion, PHA is not only an anatomic variation but also a possible cause of a neurovascular compression syndrome leading to intermittent HN palsy. PMID:23020989

    Hoarseness of voice due to vocal cord paresis as a result of recurrent laryngeal nerve palsy has been well recognised. Recurrent laryngeal nerve palsy is commonly caused by compression due to tumour or lymph nodes or by surgical damage. Vinca alkaloids are well known to cause peripheral neuropathy. However, vinca alkaloids causing recurrent laryngeal nerve palsy has been reported rarely in children. We report a case of an adult patient with HIV who developed hoarseness of voice due to vocal cord paralysis during vinblastine treatment for Hodgkin lymphoma. Mediastinal and hilar lymph node enlargement in such patients may distract clinicians from considering alternative causes of recurrent laryngeal nerve palsy, with potential ensuing severe or even life-threatening stridor.

    Pituitary apoplexy is a clinical syndrome caused by an acute ischemic or hemorrhagic vascular accident involving a pituitary adenoma or an adjacent pituitary gland. Pituitary apoplexy may be associated with a variety of neurological and endocrinological signs and symptoms. However, isolated third cranial nerve palsy with ptosis as the presenting sign of pituitary apoplexy is very rare. We describe two cases of pituitary apoplexy presenting as sudden-onset unilateral ptosis and diplopia. In one case, brain magnetic resonance imaging (MRI) revealed a mass in the pituitary fossa with signs of hemorrhage, upward displacement of the optic chiasm, erosion of the sellar floor and invasion of the right cavernous sinus. In the other case, MRI showed a large area of insufficient enhancement in the anterior pituitary consistent with pituitary infarction or Sheehan's syndrome. We performed neurosurgical decompression via a transsphenoidal approach. Both patients showed an uneventful recovery. Both cases of isolated third cranial nerve palsy with ptosis completely resolved during the early postoperative period. We suggest that pituitary apoplexy should be included in the differential diagnosis of patients presenting with isolated third cranial nerve palsy with ptosis and that prompt neurosurgical decompression should be considered for the preservation of third cranial nerve function.

    Great importance and caution should be placed on prosthetic fitting for a paraplegic patient with an anesthetic residual limb if functional ambulation is to be achieved. The combination of paraplegia with a transfemoral amputation and radial nerve palsy is a complex injury that makes the rehabilitation process difficult. This article describes a case of L2 paraplegia with a transfemoral amputation and radial nerve palsy on the right side. Following the rehabilitation course, the patient independently walked using a walker at indoor level with a transfemoral prosthesis with ischial containment socket, polycentric knee assembly, endoskeletal shank and multiaxis foot assembly and a knee ankle foot orthosis on the sound side. The difficulties of fitting a functional prosthesis to an insensate limb and the rehabilitation stages leading to functional ambulation are reviewed. PMID:10992814

    Aim Occurrence of ocular motor cranial nerve palsies (OMCNP), following stroke, has not been reported in relation to the type of OMCNP seen and in relation to brain area affected by stroke. The aim of this study was to identify all patients referred with suspected visual impairment to establish the presence and type of OMCNP. Methods Prospective, observation study with standardised referral and assessment forms across 20 sites. Visual assessment included visual acuity measurement, visual field assessment, ocular alignment, and movement and visual inattention assessment. Multicentre ethics approval and informed patient consent was obtained. Results In total, 915 patients were recruited with mean age of 69.18 years (SD 14.19). Altogether, 498 patients (54%) were diagnosed with ocular motility abnormalities. Of these, 89 patients (18%) had OMCNP. Unilateral third nerve palsy was present in 23 patients (26%), fourth nerve palsy in 14 patients (16%), and sixth nerve palsy in 52 patients (58%). Out of these, 44 patients had isolated OMCNP and 45 had OMCNP combined with other ocular motility abnormalities. Location of stroke was reported mainly in cerebellum, brain stem, thalamus, and internal and external capsules. Treatment was provided for each case including prisms, occlusion, typoscope, scanning exercises, and refraction. Conclusions OMCNP account for 18% of eye movement abnormalities in this stroke sub-population. Sixth CNP was most common, followed by third and fourth CNP. Half were isolated and half combined with other eye movement abnormality. Most were treated with prisms or occlusion. The reported brain area affected by stroke was typically the cerebellum, brain stem, and diencephalic structures. PMID:21475314

    A small but relatively constant proportion (3-5%) of mice chronically infected with Mycobacterium lepraemurium (MLM) develops bilateral paralysis of the rear limbs. The aim of the study was to investigate whether or not the bilateral leg palsy results from nerve involvement. Direct bacterial nerve infection or acute/delayed inflammation might possibly affect the nerves. Therefore, palsied animals were investigated for the presence of: (a) histopathological changes in the leg tissues including nerves, bones and annexes, and (b) serum antibodies to M. lepraemurium and M. leprae lipids, including phenolic glycolipid I from M. leprae. Histopathological study of the palsied legs revealed that the paralysis was not the result of direct involvement of the limb nerves, as neither bacilli nor inflammatory cells were observed in the nerve branches studied. Antibodies to brain lipids and cardiolipin were not detected in the serum of the palsied animals, thus ruling out an immune response to self-lipids as the basis for the paralysis. Although high levels of antibodies to MLM lipids were detected in the serum of palsied animals they were not related to limb paralysis, as the nerves of the palsied legs showed no evidence of inflammatory damage. In fact, nerves showed no evidence of damage. Paralysis resulted from severe damage of the leg bones. Within the bones the bone marrow became replaced by extended bacilli-laden granulomas that frequently eroded the bone wall, altering the normal architecture of the bone and its annexes, namely muscle, tendons and connective tissue. Although this study rules out definitively the infectious or inflammatory damage of nerves in murine leprosy, it opens a new avenue of research into the factors that participate in the involvement or the sparing of nerves in human and murine leprosy, respectively.

    Facial nerve edema is an important finding in Bell's palsy patients. Inflammation may cause facial nerve edema, and mechanical compression and ischemic change of the facial nerve may occur in the facial nerve canal. A few studies have reported the dimensions of the facial nerve canal using conventional computed tomography or human temporal bone sections. However, the cross-sectional area of the facial nerve canal has not been fully understood. Therefore, the cross-sectional area of the facial nerve canal was measured in patients with unilateral Bell's palsy by computer tomography with multiplanar reconstruction. Sixteen patients with unilateral Bell's palsy were enrolled. Computed tomography of the temporal bone was performed, and perpendicular images to the facial nerve canal were reconstructed by the multiplanar reconstruction technique. The cross-sectional area of the facial nerve canal on the affected and unaffected sides was measured at the labyrinthine segment, the horizontal segment, and the mastoid segment. Both in the labyrinthine and horizontal segments, the mean cross-sectional area of the facial nerve canal was significantly smaller on the affected side than on the unaffected side. There was no significant difference between the affected and unaffected sides in the cross-sectional area of the facial nerve canal in the mastoid segment. The labyrinthine segment was the narrowest segment in the facial nerve canal. These findings suggest that the facial nerve is vulnerable, especially in the labyrinthine segment of the facial nerve canal, and a narrow facial nerve canal may be one of the risk factors for Bell's palsy.

    Controversy persists over the use of the flexor carpi ulnaris for transfer to the extensor digitorum communis in the treatment of radial nerve palsy. Six patients with complete, irreparable radial nerve palsies were treated in part with the flexor carpi ulnaris to extensor digitorum communis tendon transfer (standard transfers: pronator teres to extensor carpi radialis brevis, flexor carpi ulnaris to extensor digitorum communis, and palmaris longus to the rerouted extensor pollicis longus) and were functionally tested for long-term results. The average follow-up time was 8 years (range, 3-15). A control group was comprised of 10 volunteers of similar demographics. This study evaluates the long-term functional recovery in three categories: range of motion, dynamic power of wrist motion, and functional ability as determined by work simulation techniques. The activities simulated were swinging a hammer, sawing wood, tightening screws, and using pliers. A functional range of motion was maintained in all patients, and the power of wrist motion was sufficient to perform all activities of daily living. The work simulation testing revealed no significant difference between the tendon transfer patients and control group with respect to hand dominance and normal variance. All patients were able to perform the simulated work with the same variance in power as the control group. Despite the obvious anatomic loss, wrist function is not significantly impaired after flexor carpi ulnaris tendon transfer for radial nerve palsy. PMID:8522738

    Dislocation of the radial head is often encountered as a result of a pediatric Monteggia fracture. We report two rare cases of tardy ulnar nerve palsy associated with anterior radial head dislocation combined with anterior bowing of the ulna. They had cubitus valgus deformity, valgus instability, and osteoarthritis of the elbow, and had elbow injury more than 40 years back. They were diagnosed with chronic radial head dislocation long after a Bado type 1 Monteggia fracture. Anterior subcutaneous ulnar nerve transposition yielded favorable results. It is important to recognize the possibility of tardy ulnar nerve palsy caused by an improperly treated Monteggia fracture. PMID:26986030

    Background Endoscopic surgical techniques with robotic system in the thyroid cancer have been reported to show good results and advantages; however the risk of these techniques has not been fully documented. Presentation of the case We experienced an uncommon complicated case of a 20-year-old woman with a papillary thyroid carcinoma. After the robotic thyroidectomy, she complained of the tongue deviation, speech and swallowing difficulties of hypoglossal nerve palsy. Discussion In this case, a few etiologies could be suggested for the development of hypoglossal nerve palsy. It might be associated with direct stretching or entrapment of hypoglossal nerve during tumor resection; lateral placement of the laryngoscope on the tongue base; the hyperinflation of the laryngeal mask airway; and histological disruption of the intraneural connective tissue and blood circulation. Conclusion Although the robotic surgery is a creative technique and has been known to be safe and effective, the risk of this surgery including traumatic nerve injury should be taken into account before surgery.

    We present an unusual patient with a medical history of a fibrosing pseudotumor of the left orbit that had been stable for 8 years who presented with acute anterior hypophyseal failure. During the next 10-month period, sequential magnetic resonance scans showed a rapid growth of a plaque-like sellar and parasellar mass extending into the right cavernous sinus, right Meckel's cave, along the dural surfaces of the clivus, dens, and body of the second cervical vertebra. A transsphenoidal biopsy revealed sphenoid and intrasellar pseudotumor that invaded the adenohypophysis and had microscopic features identical to those of the previously excised orbital pseudotumor. Rapid growth of the pseudotumor continued despite a course of radiotherapy. Palsies of cranial nerves V and VI and of the sensory root of the cranial nerve VII developed on the right side. Steroid therapy was associated with improvement of the cranial nerve palsies. This is the first report of the sellar fibrosing pseudotumor producing not only anterior hypophyseal failure, but also cranial nerve dysfunction secondary to plaque-like extension into the cavernous sinus, Meckel's cave, and cranial base dura. This intracranial plaque-like extension of a fibrous pseudotumor corresponds to a hypertrophic intracranial pachymeningitis, which is a rare, previously described phenomenon associated to the syndrome of multifocal fibrosclerosis.

    Cement extrusion into the pelvis with subsequent palsy of the obturator and femoral nerves is a rare entity after hip replacement surgery. Cemented fixation of the acetabular cup has been considered as a safe and reliable standard procedure with very good long term results. We present a case of fifty year old female patient after hip arthroplasty procedure which suffered an obturator and femoral nerve palsy caused by extrusion of bone cement into the pelvis. Postoperative X-rays and CT-scan of the pelvis demonstrated a huge mass consisted of bone cement in close proximity of femoral and obturator nerves. The surgery charts reported shallow and weak bony substance in postero-superior aspect of the acetabulum. This weak bony acetabular substance may have caused extrusion of bone cement during press-fitting of the polyethylene cup into the acetabulum, and the following damage of the both nerves produced by polymerization of bone cement. The bone cement fragment has been surgically removed 3 weeks after arthroplasty. The female patient underwent intensive postoperative physical therapy and electro stimulation which resulted in full recovery of the patient to daily routine and almost normal electromyography results.

    Sciatic nerve injury is one of the frequent mononeuropathies in children that occurs due to different causes such as nerve compression, trauma and stretch during surgery. Gluteal injection is an uncommon cause of sciatic injury in developed countries. Poor techniques and frequent injections are the common cause of injection palsy. Proneal division of the sciatic nerve is more prone to injury due to anatomic and structural characteristics. The diagnosis is based on electrophysiological studies and the recovery rate is poor. In this study, in a period of 2 years between 2012 and 2013, we report seven children under 6 years old (three females and four males) with abnormal gait and foot pain following gluteal injection in pediatric electrodiagnostic center. Five children had proneal component and two with tibial component injuries. Five children were followed for one year and only one showed good recovery. PMID:26401156

    Minimally invasive plate osteosynthesis is a widely used procedure for the treatment of fractures of the femur and the tibia. For a short time it is also used for the treatment of humeral shaft fractures. Among other advantages, the ambassadors of this technique emphasize the lower risk of nerve injuries when compared to open reduction and internal fixation. We report the case of secondary radial nerve palsy caused by percutaneous fixation of a plate above the antecubital fold. The nerve did not recover and the patient needed a tendon transfer to regain active extension of the fingers. This case points to the importance of adequate exposure of the bone and plate if a humeral shaft fracture extends far distally. PMID:26558125

    In two randomized prospective studies of brain tumor PDT more than 180 patients have been accrued. At the Toronto site we recognized two patients who developed a lower motor neuron (LMN) facial paralysis in the week following the PDT treatment. In both cases a temporal lobectomy was undertaken and the residual tumor cavity was photo-illuminated. The surface illuminated included the temporal fossa floor, thus potentially exposing the facial nerve to the effect of PDT. The number of frontal, temporal, parietal, and occipital tumors in this cohort was 39, 24, 12 and 4, respectively. Of the 24 temporal tumors 18 were randomized to Photofrin-PDT. Of these 18 a temporal lobectomy was carried out exposing the middle fossa floor as part of the tumor resection. In two of the 10 patients where the lobectomy was carried out and the fossa floor was exposed to light there occurred a postoperative facial palsy. Both patients recovered facial nerve function in 6 and 12 weeks, respectively. 46 J/cm2 were used in the former and 130 J/cm2 in the latter. We did not encounter a single post-operative LMN facial plasy in the 101 phase 2 patients treated with Photofrin-PDT. Among 688 supratentorial brain tumor operations in the last decade involving all pathologies and all locations no case of early post-operative LMN facial palsy was identified in the absence of PDT. One further patient who had a with post-PDT facial palsy was identified at the Denver site. Although it is possible that these patients had incidental Bell's palsy, we now recommend shielding the temporal fossa floor during PDT.

    A 19-year-old male subject was diagnosed with medial meniscal, lateral meniscal and anterior cruciate ligament (ACL) tear. The symptoms did not subside after 4 months of physical therapy, and he underwent arthroscopic partial medial and lateral meniscectomy and ACL reconstruction. Immediately after the patient woke up from general anesthesia, he started experience loss of sensation in the area of superficial peroneal nerve with inverted dorsiflexion of foot and ankle. Instantly, the bandage and knee brace was removed and a diagnosis of compartment syndrome was ruled out. After eight hours, post-operatively, the patient started receiving physiotherapy. He complained of numbness and tingling in the same area. After 24 h, post-operatively, the patient started to regain dorsiflexion and eversion gradually. Two days after the surgery, the patient exhibited complete recovery of neurological status. PMID:27478579

    Objective Vertical rectus transposition (VRT) is used to treat abduction limitation, but new vertical deviations and anterior segment ischemia are concerns. Johnston and Crouch described superior rectus transposition (SRT), a procedure in which only the superior rectus muscle is transposed temporally. We describe our results using augmented temporal SRT with adjustable medial rectus muscle recession (MRc) for treatment of Duane syndrome I (DS) and sixth nerve palsy. Methods Retrospective surgical case review of patients undergoing the SRT procedure. Pre- and post-operative orthoptic measurements were recorded. Minimum follow-up was 6 weeks. Main outcome measures included angle of esotropia in primary position and the angle of head turn. Secondary outcomes included duction limitation, stereopsis, and new vertical deviations. Results The review identified seventeen patients (10 with DS and 7 with sixth nerve palsy). SRT+MRc improved esotropia [from 44 PD to 10.1 PD (p< 0.0001)], reduced abduction limitation [from −4.3 to −2.7 (p<0.0001)] and improved compensatory head posture [from 28°to 4° (p<0.0001)]. Stereopsis was recovered in eight patients (p=0.03). Three patients required a reoperation; one for overcorrection and 2 for undercorrection. A new primary position vertical deviation was observed in 2/7 patients with complex sixth nerve palsy and 0/10 DS patients. No patient described torsional diplopia. Conclusions SRT allows for the option of simultaneous medial rectus recession in patients with severe abduction imitation who require transposition surgery. SRT+MRc improved esotropia, head position, abduction limitation, and stereopsis without inducing torsional diplopia. PMID:22332212

    We report the case history of a patient with a sphenoid sinus mucocoele detected by computed tomography and medical resonance imaging. The patient had a history of nasopharyngeal carcinoma, which was treated by radiotherapy more than 10 years previously. He presented with bilateral twelfth and sixth cranial nerve palsies. Local tumour recurrence was suspected. Further investigations showed that the cranial nerve palsies were caused by radiation damage and the sphenoid sinus mucocoele was an incidental finding. Sphenoid sinus mucocoele is a possible rare late complication of radiotherapy in patients with nasopharyngeal carcinoma. PMID:11716228

    Here, we report successful anesthetic management of posterior cervical spinal fusion utilizing block of the frontal nerve, the greater occipital nerve, and the superficial cervical plexus in a patient with athetoid cerebral palsy. A 69-year-old woman (height 157 cm; weight 33 kg) with athetoid cerebral palsy was scheduled to undergo posterior cervical spinal fusion for cervical spondylotic myelopathy. After induction of general anesthesia, we performed tracheal intubation using the Pentax-AWS Airwayscope with a thin Intlock. After tracheal intubation, we used ropivacaine for the frontal nerve, greater occipital nerve, and superficial cervical plexus block. Anesthetic maintenance was performed with total intravenous anesthesia utilizing propofol and remifentanil. Continuous administration of dexmedetomidine was started during operation. Following surgery, smooth spontaneous ventilation was observed following uneventful extubation. No significant pain and no athetoid movement were observed under continuous administration of dexmedetomidine. PMID:26422967

    From January 1978 to December 1988, 109 phrenic nerve paralyses (PNP) occurred in a total of 9149 cardiac operations performed in a population of patients younger than 15 years old (1.2%) whose age varied from 1 day to 15 years old and mean weight was 11.3 +/- 8.7 kg. PNP was diagnosed in 43 patients after closed procedures (1.2% of 3509 procedures) and in 66 patients after open heart operations (1.2% of 5640 operations). PNP was right sided in 49 cases and left sided in 60 cases. Open heart operations that predisposed to PNP were those which needed harvesting of autologous pericardium (P less than 0.0001) and wide exposure of the great vessels. The modified right Blalock-Taussig shunt was the main cause of PNP in closed procedures (P less than 0.02). Small children tolerated PNP less well. They needed longer ventilatory support (P less than 0.0005) and developed more respiratory complications. Seventeen children underwent plication of the affected hemidiaphragm and could be subsequently extubated. It is concluded that for prevention of PNP, a high level of attention should be exercised in neonates and small children, particularly when pericardium is harvested or when exposure needs extensive dissection of the great vessels and thymus resection, or at reoperation. We also prefer to avoid the use of iced slush lavage. PNP, when symptomatic, is best managed by continuous positive airway pressure (CPAP) ventilation. Diaphragmatic plication is recommended when after 2-3 weeks there is no recovery of diaphragmatic function or when there are troublesome respiratory complications. PMID:2171593

    Summary Endovascular packing of intracranial aneurysm with preservation of the parent vessel has become in many cases a valid alternative to surgical clipping. Regression of oculomotor disorders after clipping of internal carotid-posterior communicating artery (ICA-PCoA) aneurysms has been well assessed. This report focuses on the reversal of third nerve palsy after endovascular packing of ICA-PCoA aneurysms. To this end, clinical appearances, neuroradiological features, and endovascular interventional procedures of six treated patient are reported and discussed in the light of the very few previous case observations found in the literature. Results indicate that endovascular packing of ICA-PCoA aneurysms may produce effective recovery of correlated third nerve dysfunction. PMID:20667199

    We describe a case in which an anatomic diagnosis was useful for diagnosing and estimating the cause of femoral nerve palsy following gynecologic surgery. A 49-year-old female received general and epidural anesthesia for radical ovarian cancer surgery. Although injection pain was noted in the left medial shin with 1 % mepivacaine administered as a test dose, the catheter was left indwelling because it improved her symptoms. The surgery, which lasted 195 min, was performed in the lithotomy position, and a self-retained retractor was used to gain a good surgical field. Postoperatively, the patient complained of difficulty in stretching her knee joint and left lower limb paresthesia that did not improve after stopping continuous epidural administration. A spinal cord injury related to epidural anesthesia was suspected because the sites of sensory impairment and epidural injection pain were the same; however, the patient had greater weakness of the quadriceps muscle than the iliopsoas, and no other muscle weakness was observed. These findings and previous reports suggest that her femoral nerve palsy was caused by compression of the inguinal ligament from the self-retaining retractor and lithotomy position. Twenty months after surgery, her muscle strength had fully recovered. PMID:26661449

    Purpose: To evaluate various prognostic factors and the impact of imaging modalities on tumor control in patients with nasopharyngeal cancer (NPC) with cranial nerve (China) palsy. Material and Methods: Between September 1979 and December 2000, 330 NPC patients with CN palsy received radical radiotherapy (RT) by the conventional opposing technique at Chang Gung Memorial Hospital-Linkou. Imaging methods used varied over that period, and included conventional tomography (Tm) for 47 patients, computerized tomography (CT) for 195 patients, and magnetic resonance image (MRI) for 88 patients. Upper CN (II-VI) palsy was found in 268 patients, lower CN (IX-XII) in 13, and 49 patients had both. The most commonly involved CN were V or VI or both (23%, 12%, and 16%, respectively). All patients had good performance status (World Health Organization <2). The median external RT dose was 70.2 Gy (range, 63-77.5 Gy). Brachytherapy was also given to 156 patients in addition to external RT, delivered by the remote after-loading, high-dose-rate technique. A total of 139 patients received cisplatin-based chemotherapy, in 115 received as neoadjuvant or adjuvant chemotherapy and in 24 concomitant with RT. Recovery from CN palsy occurred in 171 patients during or after radiotherapy. Patients who died without a specific cause identified were regarded as having died with persistent disease. Results: The 3-year, 5-year, and 10-year overall survival was 47.1%, 34.4%, and 22.2%. The 3-year, 5-year, and 10-year disease-specific survival (DSS) rates were 50.4%, 37.8%, and 25.9%. The 5-year DSS for patients staged with MRI, CT, and Tm were 46.9%, 36.7%, and 21.9%, respectively (p = 0.016). The difference between MRI and CT was significant (p = 0.015). The 3-year and 5-year local control rates were 62% and 53%, respectively. The 5-year local control was 68.2% if excluding patients who died without a specific cause. Patients who had an MRI had a significantly better tumor control rate than those

    Esotropia from chronic sixth nerve palsy or paresis usually requires surgery. Chemodenervation of the antagonist medial rectus muscle, while popular for the treatment of acute sixth nerve palsies and pareses, has not been used extensively for chronic cases. In this study, 22 patients with sixth nerve palsies or partially recovered palsies of greater than 5 months duration were treated with chemodenervation. The etiologies of the sixth nerve palsies were trauma (n = 7), tumor (n = 4), infection/inflammation (n = 3), nerve compression from aneurysm or increased intracranial pressure (n = 4), congenital (n = 1), ischemia (n = 2), and idiopathic (n = 1). The mean preinjection deviation was 41 prism diopters. A total of 38 injections were administered (mean, 1.7 per patient). Each patient received an injection of 2.5 to 7.5 units (mean, 4.1) of botulinum neurotoxin A to the ipsilateral medial rectus muscle. Treatment success was assessed 6 months after the last injection. A course of chemodenervation significantly improved the alignment of 9 of the 22 patients (41%). The mean postinjection deviation was 8 delta. Seven patients (32%) had single binocular vision in primary position restored. These patients had a mean horizontal binocular field of 70 degrees (range, 40 degrees to 100 degrees). Thirteen patients (59%) had only modest improvement and required surgery. The data suggest that injection of botulinum neurotoxin A is a useful treatment for some patients with chronic sixth nerve weakness. A course of chemodenervation therapy compares less favorably with transposition surgery with concomitant neurotoxin injection for the treatment of these difficult problems. PMID:8014791

    Because the use of arthroscopy has increased recently for the treatment of elbow lesions, reports of complications have become more common. Nerve injury after arthroscopic anterior capsular release is an extremely rare complication, with 4 reported cases worldwide. We usually use a sharp-tipped electrocautery device with a 0.5-mm diameter during arthroscopic capsular release. In this case, because the former was not prepared, we used a ball-tipped electrocautery device with a 3-mm diameter. Herein, we experienced a case of radial nerve palsy after arthroscopic anterior capsular release using a ball-tipped electrocautery device on a degenerative elbow contracture. We supposed that the electrocautery device caused transiently thermal injury of the radial nerve despite proper portal entry site, intra-articular distension, and gentle arthroscopic manipulation. Elbow arthroscopy remains a technically difficult procedure with the potential for neurologic complications. To perform surgery safely, knowledge of the regional neuroanatomy and a thorough understanding of proper instrument usage are required. PMID:18063186

    Introduction: The injury pattern of open fracture dislocation of elbow with fracture both bones forearm with radial nerve injury is very rare. Very few reports are there in literature related to this kind of injury. However this combination is first of its kind. This rare injury needs special attention by early intervention and biological fixation to achieve good results. Case Report: A 22 year old female presented to us with history of road traffic accident. On evaluation patient had combination of open fracture dislocation of elbow with open diaphyseal fracture of both forearm bones with radial nerve palsy. The patient was treated in emergency and followed for 2 years. Conclusion: Open fracture dislocation of elbow is a rare entity. Our case additionally had open fracture both the bones forearm with radial nerve palsy. Early intervention and biological fixation with minimal invasion gives good results in terms of range of movements and patient satisfaction. PMID:27298951

    ABSTRACT Objective: To evaluate the distribution of SP (substance P) and S-100 peptide immunoreactivity, as well as the vascular supply of tissues commonly used as grafts for anterior cruciate ligament (ACL) reconstruction. A second aim was to compare the above mentioned distribution in the semitendinosus muscle tendons of cerebral palsy (CP) patients with the semitendinosus muscle tendons and patellar tendons of patients without CP. Methods: The first group consisted of 14 children with cerebral palsy with a mean age of 11.7 years old. At the time of hamstring lengthening operation, a sample of semitendinosus muscle was taken for analysis. The second group comprised 20 patients treated for isolated ACL rupture of the knee (mean age 32 years old). Group three comprised ten patients in the mean age of 14.3 years old treated for recurrent lateral patellar dislocation, and from whom a sample of patellar tendon was obtained. Results: No statistically significant differences were demonstrated with regard to the amount of immunopositive nerve fibers expressing SP or S-100 in all 3 groups of patients. A significant difference was noted in the number of blood vessels between the adult and child semitendinosus muscles, but not between the semitendinosus muscles and patellar tendon of children. Conclusion: The number of nociceptors as well as proprioceptive fibers is similar in patients with CP and patients from a neurologically healthy population. Level of Evidence IV, Cases Series.

    An increasingly reported entity, Lemierre's syndrome classically presents with a recent oropharyngeal infection, internal jugular vein thrombosis and the presence of anaerobic organisms such as Fusobacterium necrophorum. The authors report a normally fit and well 17-year-old boy who presented with severe sepsis following a 5-day history of a sore throat, myalgia and neck stiffness requiring intensive care admission. Blood cultures grew F. necrophorum and radiological investigations demonstrated left internal jugular vein, cavernous sinus and sigmoid sinus thrombus, left vertebral artery dissection and thrombus within the left internal carotid artery. Imaging also revealed two areas of acute ischaemia in the brain, consistent with septic emboli, skull base (clival) osteomyelitis and an extensive epidural abscess. The patient improved on meropenem and metronidazole and was warfarinised for his cavernous sinus thrombosis. He has an on-going left-sided hypoglossal (XIIth) nerve palsy. PMID:26323975

    Purpose: To evaluate the demographics and management outcomes of strabismus surgery in patients with third cranial nerve palsy. Methods: This retrospective study includes subjects with third cranial nerve palsy. We evaluated age, sex, laterality, severity of involvement, etiology, frequency of clinical findings, and types and results of treatments. Results: 52 patients including 29 male and 23 female subjects with mean age of 21.1±15.5 years were studied between January 1999 and January 2009. Etiologies of third nerve palsy included congenital in 16 (30.8%), trauma in 26 (50%) and other causes in 10 (19.2%) patients. In 24 patients (46.2%), the palsy was complete. The most common type of strabismus was exotropia associated with hypotropia (40%). Medical treatment was used in 25 (48%) and surgical treatment in 46 (88.4%) subjects. One time strabismus surgery was performed in 30 (65.2%), 2 times in 11 (24%) and 3 times in 5 (10.8%) subjects. The most common operation was large horizontal recession and resection in 78.2% of cases. Mean horizontal deviation in primary position was 66±29 prism diopters (PD) before surgery decreasing to 21±19, 13±12 and 6±8 PD after first, second and third surgery, respectively. Corresponding figures for mean vertical deviation were 13±15, 7±12, 4±6 and 1±2 PD, respectively. Abnormal head posture was 10-30° in 11 (21.1%) cases before treatment which completely resolved after surgery. Conclusion: Surgical management of strabismus in patients with third nerve palsy is difficult and challenging, however the majority of patients achieve ideal results with appropriate and stepwise surgical plans.

    Delayed lesions of the femoral or sciatic nerve are a rare complication after total hip arthroplasty. Several cases in association with cement edges, scar tissue, broken cerclages, deep hematoma, or reinforcement rings have been published. We report about a 62-year-old female who developed a pure motor paresis of the quadriceps muscle 2 weeks after total hip arthroplasty. After electrophysiological evaluation had revealed an isolated femoral nerve lesion, revision of the femoral nerve was performed. During operative revision no pathologic findings could be seen. One week later the patient developed paralysis of the left wrist and finger extensors after using crutches. Electrophysiological evaluation revealed several nerve conduction blocks in physiological entrapments and the diagnosis of hereditary neuropathy with liability to pressure palsies (HNPP) was established. Hereditary neuropathy with liability to pressure palsies (HNPP) is a rare disease with increased vulnerability of the peripheral nerve system with mostly reversible sensorimotor deficits. It should be taken into consideration in cases of atypical findings of compression syndromes of peripheral nerves or delayed neuropathy, e. g., after total hip arthroplasty. PMID:15083272

    Sciatic nerve palsy following total hip replacement is a rare but serious complication. The neurological sequelae that follow range from pure sensory loss to combined motor and sensory loss involving most of the lower limb. The loss of nociceptive feedback predisposes patients to accidental damage to the lower limb. We present the case of a lady with sciatic nerve palsy who sustained full-thickness burn injuries to her foot via a hot water bottle. The dilemma between debridement and grafting following a recent history of surgical trauma (ie, total hip replacement) versus secondary healing via dressings and regular review is discussed. Although grafting is the standard treatment in such burns, we recommend secondary healing over grafting provided the burns are not extensive. This enables potential recovery of sensation and reduces operative trauma to the limb which may retard resolution of the neuropraxia. PMID:23595171

    We report a case of an 80-year-old woman being treated with rituximab and maintenance corticosteroids for long-standing scleroderma who presented with right-sided third nerve palsy. Radiological investigations including CT, MRI and MR angiography of the brain were unremarkable. The patient was discharged with a diagnosis of probable microvascular third nerve palsy but was readmitted 1 week later with total visual loss in her left eye. Despite the absence of diagnostic clinical signs, giant cell arteritis (GCA) was suspected, and she was started on intravenous corticosteroids. Left temporal artery biopsy subsequently confirmed histological findings diagnostic of GCA. Unfortunately, she remained blind in the left eye. PMID:27068727

    Shoulder arthroscopy is a common treatment for numerous different pathologies. An iatrogenic nerve injury that occurs during shoulder arthroscopy is more common than previously recognized. However, though many nerve pathologies are increasingly being recognized, reported cases of greater auricular nerve injury are limited. For instance, a case of greater auricular nerve palsy was reported in only 2 series that used a horseshoe headrest. One set of authors discontinued and recommended against use of this headrest, and the other recommended a headrest redesign. Here we report on a case of greater auricular nerve palsy that occurred after the patient's anterior-inferior and posterior-inferior labral tear was arthroscopically repaired using beach-chair positioning and a standard universal headrest. The palsy resulted in numbness and dysesthesia, which lessened gradually over 3 months after surgery and was completely resolved by 6 months. PMID:25844590

    Peripheral facial nerve palsy (FNP) is the most common cranial nerves neuropathy. It is very rare during dental treatment. Classically, it begins immediately after the injection of local anaesthetic into the region of inferior dental foramen and it's homolateral to the injection. Recovery takes a few hours, normally as long the anaesthetic lasts. The authors present a 44-year-old patient who presented a contralateral delayed-onset facial paralysis arising from dental procedure and discuss the plausible pathogenesis mechanism of happen and a possible relationship between dental procedure and contralateral FNP.

    A 42-year-old woman was surgically treated for carpal tunnel syndrome, revealing schwannoma of the median nerve. A year later, she developed a tarsal tunnel syndrome. At time of this diagnosis, hereditary neuropathy with liability to pressure palsies (HNPP) was diagnosed genetically and a schwannoma of the medial plantar nerve was treated surgically. The occurrence of HNPP and schwannomas in the same patient might be purely coincidental, but it is tempting to speculate that they share a common genetic basis. PMID:16969831

    A multiple-ligament knee injury that includes posterolateral corner (PLC) disruption often causes palsy of the common peroneal nerve (CPN), which occurs in 44% of cases with PLC injury and biceps femoris tendon rupture or avulsion of the fibular head. Approximately half of these cases do not show functional recovery. This case report aims to present a criteria-based approach to the operation and postoperative management of CPN palsy that resulted from a multiple-ligament knee injury in a 22-year-old man that occurred during judo. We performed a two-staged surgery. The first stage was to repair the injuries to the PLC and biceps femoris. The second stage involved anterior cruciate ligament reconstruction. The outcomes were excellent, with a stable knee, excellent range of motion, and improvement in the palsy. The patient was able to return to judo competition 27 weeks after the injury. To the best of our knowledge, this is the first case report describing a return to sports following CPN palsy with multiple-ligament knee injury. PMID:26064740

    Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominantly inherited disorder that affects peripheral nerves by repeated focal pressure. HNPP can be diagnosed by clinical findings, electrodiagnostic studies, histopathological features, and genetic analysis. Ultrasonography is increasingly used for the diagnosis of neuromuscular diseases; however, sonographic features of HNPP have not been clearly defined. We report the sonographic findings and comparative electrodiagnostic data in a 73-year-old woman with HNPP, confirmed by genetic analysis. The cross-sectional areas of peripheral nerves were enlarged at typical nerve entrapment sites, but enlargement at non-entrapment sites was uncommon. These sonographic features may be helpful for diagnosis of HNPP when electrodiagnostic studies are suspicious of HNPP and/or gene study is not compatible. PMID:24639934

    Peroneal nerve palsy is an infrequent but potential complication of childbirth. Bilateral peroneal palsy is particularly rare following delivery with few reported cases. A 38-year-old gravida 1, para 0 underwent a prolonged second stage of labor, was diagnosed with an arrest of descent, and subsequently underwent an uncomplicated primary cesarean section. The patient was diagnosed with bilateral peroneal neuropathy four days after delivery. By two months postpartum, her foot drop had improved by 85% and the remainder of her symptoms resolved. Awareness of the risks of a peroneal neuropathy as well as implementation of preventive measures is important for members of the delivery team. Regional anesthesia during labor is a risk factor for the development of a peroneal neuropathy. PMID:25180116

    OBJECTIVE Transfer of the spinal accessory nerve to the suprascapular nerve is a common procedure, performed to reestablish shoulder motion in patients with total brachial plexus palsy. However, the results of this procedure remain largely unknown. METHODS Over an 11-year period (2002-2012), 257 patients with total brachial plexus palsy were operated upon in the authors' department by a single surgeon and had the spinal accessory nerve transferred to the suprascapular nerve. Among these, 110 had adequate follow-up and were included in this study. Their average age was 26 years (SD 8.4 years), and the mean interval between their injury and surgery was 5.2 months (SD 2.4 months). Prior to 2005, the suprascapular and spinal accessory nerves were dissected through a classic supraclavicular L-shape incision (n = 29). Afterward (n = 81), the spinal accessory and suprascapular nerves were dissected via an oblique incision, extending from the point at which the plexus crossed the clavicle to the anterior border of the trapezius muscle. In 17 of these patients, because of clavicle fractures or dislocation, scapular fractures or retroclavicular scarring, the incision was extended by detaching the trapezius from the clavicle to expose the suprascapular nerve at the suprascapular fossa. In all patients, the brachial plexus was explored and elbow flexion reconstructed by root grafting (n = 95), root grafting and phrenic nerve transfer (n = 6), phrenic nerve transfer (n = 1), or third, fourth, and fifth intercostal nerve transfer. Postoperatively, patients were followed for an average of 40 months (SD 13.7 months). RESULTS Failed recovery, meaning less than 30° abduction, was observed in 10 (9%) of the 110 patients. The failure rate was 25% between 2002 and 2004, but dropped to 5% after the staged/extended approach was introduced. The mean overall range of abduction recovery was 58.5° (SD 26°). Comparing before and after distal suprascapular nerve exploration (2005-2012), the

    Lower cranial and phrenic nerve involvement is exceptional in hereditary neuropathy with liability to pressure palsies (HNPP). Here we report the occurrence of reversible laryngeal and phrenic nerve involvement in a patient with HNPP. The patient recalled several episodes of reversible weakness and numbness of his feet and hands since the age of 30 years. His medical history was uneventful, apart from chronic obstructive pulmonary disease (COPD). At age 44, following severe weight loss, he presented with progressive dysphonia and hoarseness. EMG of cricoarytenoid and thyroarytenoid muscles and laryngeal fibroscopy confirmed vocal cord paralysis. These speech disturbances gradually regressed. Two years later, he reported rapidly worsening dyspnea. Electroneurography showed increased distal latency of the right phrenic nerve and diaphragm ultrasonography documented reduced right hemi-diaphragm excursion. Six months later and after optimization of CODP treatment, his respiratory function had improved and both phrenic nerve conduction and diaphragm excursion were completely restored. We hypothesize that chronic cough and nerve stretching in the context of CODP, together with severe weight loss, may have triggered the nerve paralysis in this patient. Our report highlights the need for optimal management of comorbidities such as CODP as well as careful control of weight in HNPP patients to avoid potentially harmful complications. PMID:27241821

    PurposeTo describe the occurrence and severity of upper eyelid skin contracture in facial nerve palsy (FNP).MethodsWe enroled consecutive patients with unilateral FNP into this study. Patients with previous upper eyelid surgery for either side were excluded. We developed a standardised technique to measure the distance between the upper eyelid margin and the lower border of brow (LMBD). FNP was graded using the Sunnybrook grading scale. Its aetiology, duration, and treatment were noted. Upper and lower marginal reflex distance and lagophthalmos were also noted.ResultsSixty-six patients (mean age 51 years) were included. FNP was owing to a variety of aetiologies. LMBD on the paralytic side was shorter than the normal contralateral side in 47 (71%), equal in 15 (23%), and larger in four (6%) patients. The mean contracture was 3.4 mm (median: 3, range: 1-12) with 11 (17%) patients showing 5 mm or more of skin contracture. The mean LMBD on the paralytic side in all patients was significantly smaller than the contralateral side; 30±3.7 (median: 30; 95% CI 29-31) compared with 32±3.7 (median: 32; 95% CI 32-33), respectively, P<0.0001, two-tailed paired t-test.ConclusionTo our knowledge, this is the first study that quantitatively demonstrates contraction of the upper eyelid skin in FNP. This finding is valuable in directing optimal early management to minimise skin contracture and to caution surgeons against unnecessary upper eyelid skin excision. PMID:26939561

    OBJECT Unruptured posterior communicating artery (PCoA) aneurysms with oculomotor nerve palsy (ONP) have a very high risk of rupture. This study investigated the hemodynamic and morphological characteristics of intracranial aneurysms with high rupture risk by analyzing PCoA aneurysms with ONP. METHODS Fourteen unruptured PCoA aneurysms with ONP, 33 ruptured PCoA aneurysms, and 21 asymptomatic unruptured PCoA aneurysms were included in this study. The clinical, morphological, and hemodynamic characteristics were compared among the different groups. RESULTS The clinical characteristics did not differ among the 3 groups (p > 0.05), whereas the morphological and hemodynamic analyses showed that size, aspect ratio, size ratio, undulation index, nonsphericity index, ellipticity index, normalized wall shear stress (WSS), and percentage of low WSS area differed significantly (p < 0.05) among the 3 groups. Furthermore, multiple comparisons revealed that these parameters differed significantly between the ONP group and the asymptomatic unruptured group and between the ruptured group and the asymptomatic unruptured group, except for size, which differed significantly only between the ONP group and the asymptomatic unruptured group (p = 0.0005). No morphological or hemodynamic parameters differed between the ONP group and the ruptured group. CONCLUSIONS Unruptured PCoA aneurysms with ONP demonstrated a distinctive morphological-hemodynamic pattern that was significantly different compared with asymptomatic unruptured PCoA aneurysms and was similar to ruptured PCoA aneurysms. The larger size, more irregular shape, and lower WSS might be related to the high rupture risk of PCoA aneurysms. PMID:26636379

    Leptomeningeal disease presenting with neurological dysfunction is not uncommon in leukaemia. However, it is often accompanied by abnormalities in cerebrospinal fluid (CSF) studies and/or neuroradiography. Here, the authors describe a case of a young patient presenting with sudden onset right oculomotor nerve palsy with normal neuroradiography and CSF studies, who was subsequently diagnosed to have T cell acute lymphoblastic leukaemia (T-ALL). This case highlights that neurological manifestations can be the initial presenting feature of T-ALL and can occur suddenly despite normal neuroradiography and initial CSF studies. PMID:22605802

    Internal carotid artery (ICA) lesions in the parapharyngeal space (a dissection and a pseudoaneurysm) may present as isolated lower cranial nerves (IX, X, XI, and XII) palsy (Collet-Sicard syndrome). Some arteriopathies such as fibromuscular dysplasia and tortuosity make a vessel predisposed to dissection. Extreme vessel tortuosity makes the treatment by a stent graft impossible. Two Silk stents were used in a 46 year-old man with left lower cranial nerves (IX-XII) palsy for the treatment of left ICA spontaneous dissection with pseudoaneurysm. A follow-up angiogram 5 months later confirmed pseudoaneurysm thrombosis and patency of the left ICA. The patient recovered completely from the deficits.

    Objectives To compare the surgical outcomes of inferior oblique (IO) myectomy in congenital superior oblique palsy (SOP) according to the presence of the trochlear nerve identified with high-resolution MRI. Data Extraction Forty-one congenital SOP patients without a trochlear nerve (absent group) and 23 patients with a trochlear nerve (present group) who underwent IO myectomy as the primary surgical treatment were retrospectively reviewed. “Motor success” was defined as postoperative ipsilateral hypertropia ≤ 4 prism diopter (PD). “Head tilt improvement” was regarded as postoperative angle of head tilt < 5 degrees (°). Success rates for motor alignment and head tilt improvement, cumulative probabilities of success, and factors influencing surgical responses were evaluated. Results The cumulative probabilities of motor success at 2 years after IO myectomy were 92% in patients with a trochlear nerve and 86% in patients without a trochlear nerve (P = 0.138). The cumulative probabilities of undercorrection and recurrence of hypertropia after 2 years were 0% in the present group versus 21% in the absent group (P = 0.014). The cumulative probabilities of persistent head tilt after 2 years were 14% in the present group and 20% in the absent group (P = 0.486). A younger age at operation was associated with reduced probabilities of motor success and head tilt improvement (P = 0.009, P = 0.022 respectively). A greater preoperative angle of head tilt was associated with persistent head tilt after surgery (P = 0.038). Conclusions Congenital SOP without a trochlear nerve had a higher risk of hypertropia undercorrection after IO myectomy compared to patients with a trochlear nerve. A younger age at operation and larger preoperative head tilt was related to poor outcomes. PMID:27391445

    A 51-year-old man with aldosteronism underwent laparoscopic left adrenalectomy. Anesthesia was induced with fentanyl 0.1 mg, propofol 140 mg and vecuronium 7 mg. Following endotracheal intubation, he was placed in a right lateral position with extension of his left side, and fixed with the Magic Bed. Canulation of the right radial artery was smoothly performed. Anesthesia was maintained with sevoflurane and thoracic epidural anesthesia (mepivacaine and ropivacaine). The operation lasted for 270 minutes and was uneventful. A few hours after surgery, he complained of inability to extend his right fingers without any sensory loss, and the local oppressive pain on his right forearm. Neurological examination revealed a posterior interosseous palsy. Symptoms improved gradually and disappeared completely in two months with the administration of vitamin B12 and physical therapy. Postoperative reproduction of the positioning of this case disclosed that the edge of the Magic Bed might potentially compress the posterior interosseous nerve at the point where the nerve is bifurcated from the radial nerve and travels within the supinator muscle going into the muscle again. This case indicated that we must be careful of nerve injuries due to devices used to maintain the patient in lateral position. PMID:16104549

    We report a rare case of metastasis to a preexisting pituitary adenoma. An 80-year-old man with a history of pituitary adenoma and lung cancer presented with recent onset of bilateral visual impairment, oculomotor nerve palsies, and severe headache. A CT scan revealed a pituitary tumor expanding into the suprasellar region and infiltrating the bilateral cavernous sinuses. We performed transsphenoidal surgery and diagnosed the tumor as lung cancer metastasis to the pituitary adenoma. After the surgery, visual impairment and severe headache were resolved, and the patient underwent radiation therapy for the residual tumor. To the best of our knowledge, 20 cases of metastases to pituitary adenomas have been reported in the literature. Clinical features of metastasis to a pituitary adenoma are different from those of metastasis to normal pituitary gland. In the case of a pituitary lesion with acute aggravation, one should be aware of the possibility of metastasis to preexisting pituitary adenomas. PMID:25266586

    Surgical management of complete third nerve paralysis is a challenge. While several techniques have been described over the years, they result in less than satisfactory outcomes with residual deviations in primary gaze or postoperative drifts. One of the described techniques for management of oculomotor palsy has been medial transposition of the lateral rectus muscle which provides a good surgical alternative but often can result in undercorrection. We describe a modification of the existing technique of medial transposition of the split lateral rectus by force augmentation through the use of equatorial fixation sutures resulting in an improved outcome in primary gaze alignment. The modified technique involves splitting of the lateral rectus into two halves followed by transposing the superior half from below the superior oblique and superior rectus and inferior half from below the inferior oblique and inferior rectus to attach them at the superior and inferior edge of the medial rectus insertion, respectively. This is followed by placing non-absorbable sutures to fix each split belly of the transposed muscles to the sclera at the equator adjacent to the medial rectus such that the split muscles lie nearly parallel to the medial rectus till the equator before reflecting away. These sutures augment the force of the transposed muscles by redirecting the force vectors in the direction of action of the medial rectus. Satisfactory postoperative primary gaze alignment was achieved in three cases of complete third nerve paralysis. PMID:26758537

    We report a case of first-episode sphenoid mucocele successfully treated via transnasal endoscopic drainage and marsupialization of the mucocele. A 55 year-old female presented with persistent right-side facial numbness (in the areas of the first and second branches of the trigeminal nerve) and right-side ptosis. Computed tomography (CT) imaging and Magnetic resonance imaging (MRI) revealed opacification and expansion of the right-side sphenoid sinus lesion. The lesion was diagnosed as right-side sphenoid mucocele affecting the functions of the trigeminal (first and second branches), and oculomotor nerves. Transnasal endoscopic drainage and marsupialization of the mucocele result in rapid regression of these symptoms. PMID:26629234

    Purpose: To address the characteristics and the causative factors of radiation-induced cranial nerve palsy (CNP) in nasopharyngeal carcinoma (NPC) patients with an extensive period of followed-up. Patients and Methods: A total of 317 consecutive and nonselected patients treated with definitive external-beam radiotherapy between November 1962 and February 1995 participated in this study. The median doses to the nasopharynx and upper neck were 71 Gy (range, 55-86 Gy) and 61 Gy (range, 34-72 Gy), respectively. Conventional fractionation was used in 287 patients (90.5%). Forty-five patients (14.2%) received chemotherapy. Results: The median follow-up was 11.4 years (range, 5.1-38.0 years). Ninety-eight patients (30.9%) developed CNP, with a median latent period of 7.6 years (range, 0.3-34 years). Patients had a higher rate of CNP (81 cases, 25.5%) in lower-group cranial nerves compared with upper group (44 cases, 13.9%) ({chi}{sup 2} = 34.444, p < 0.001). Fifty-nine cases experienced CNP in more than one cranial nerve. Twenty-two of 27 cases (68.8%) of intragroup CNP and 11 of 32 cases (40.7%) of intergroup CNP occurred synchronously ({chi}{sup 2} = 4.661, p = 0.031). The cumulative incidences of CNP were 10.4%, 22.4%, 35.5%, and 44.5% at 5, 10, 15, and 20 years, respectively. Multivariate analyses revealed that CNP at diagnosis, chemotherapy, total radiation dose to the nasopharynx, and upper neck fibrosis were independent risk factors for developing radiation-induced CNP. Conclusion: Radiation-induced fibrosis may play an important role in radiation-induced CNP. The incidence of CNP after definitive radiotherapy for NPC remains high after long-term follow-up and is dose and fractionation dependent.

    Several techniques have been described for smile restoration after facial nerve paralysis. When a nerve other than the contralateral facial nerve is used to restore the smile, some controversy appears because of the nonphysiological mechanism of smile recovering. Different authors have reported natural results with the masseter nerve. The physiological pathways which determine whether this is achieved continue to remain unclear. Using functional magnetic resonance imaging, brain activation pattern measuring blood-oxygen-level-dependent (BOLD) signal during smiling and jaw clenching was recorded in a group of 24 healthy subjects (11 females). Effective connectivity of premotor regions was also compared in both tasks. The brain activation pattern was similar for smile and jaw-clenching tasks. Smile activations showed topographic overlap though more extended for smile than clenching. Gender comparisons during facial movements, according to kinematics and BOLD signal, did not reveal significant differences. Effective connectivity results of psychophysiological interaction (PPI) from the same seeds located in bilateral facial premotor regions showed significant task and gender differences (p < 0.001). The hypothesis of brain plasticity between the facial nerve and masseter nerve areas is supported by the broad cortical overlap in the representation of facial and masseter muscles. PMID:26683008

    2016-08-01

    Ulnar nerve paralysis results in classic stigmata, including weakness of grasp and pinch, poorly coordinated flexion, and clawing of digits. Restoration of grasp is a key portion of the reconstructive efforts after loss of ulnar nerve function. Improving flexion at the metacarpophalangeal joint can be done by static and dynamic means, although only the latter can improve interphalangeal extension. Deformity and digital posture are more predictably corrected with surgical intervention. Loss of strength from intrinsic muscle paralysis cannot be fully restored with tendon transfer procedures. Preoperative patient education is paramount to success if realistic expectations are to be met. PMID:27387079

    We discuss a rare acute complication after Gamma Knife therapy (Elekta AB, Stockholm, Sweden) in a single patient. A 52-year-old woman presented with vertigo, facial weakness and hearing loss emerging 48hours following Gamma Knife radiosurgery for a right-sided vestibular schwannoma. Neurological examination 6days after symptom onset showed right-sided facial palsy, spontaneous left-beating nystagmus and pathologic head-impulse testing to the right. Pure-tone audiogram revealed right-sided sensorineural hearing loss. A diagnosis of acute vestibulocochlear and facial neuropathy was made. Brain MRI demonstrated focal contrast sparing within the schwannoma, likely related to acute radiation necrosis. Acute multiple cranial neuropathies of the cerebellopontine angle after Gamma Knife treatment should raise suspicion of acute tissue damage within the schwannoma and should result in urgent MRI. Treatment with steroids may be considered based on accompanying swelling and edema. PMID:26947104

    Drop foot is typically caused by neurologic disease such as lumbar disc herniation, but we report two rare cases of deep peroneal nerve palsy with isolated lateral compartment syndrome secondary to peroneus longus tears. Both patients developed mild pain in the lower legs while playing sport, and were aware of drop foot. As compartment pressures were elevated, fasciotomy was performed immediately, and the tendon of the peroneus longus was completely detached from its proximal origin. The patients were able to return their original sports after 3 months, and clinical examination revealed no hypesthesia or muscle weakness in the deep peroneal nerve area at the time of last follow-up. The common peroneal nerve pierced the deep fascia and lay over the fibular neck, which formed the floor of a short tunnel (the so-called fibular tunnel), then passed the lateral compartment just behind the peroneus longus. The characteristic anatomical situation between the fibular tunnel and peroneus longus might have caused deep peroneal nerve palsy in these two cases after hematoma adjacent to the fibular tunnel increased lateral compartment pressure.

    Individuals who sustain damage to the radial nerve experience a significant loss in functional use of the hand. Traditional orthoses have been effective in providing assistance with wrist stabilization and finger/thumb MP extension. These authors adapted a low profile orthosis to provide the necessary support while allowing radial and ulnar deviation of the wrist, thus increasing functional use of the hand.--Victoria Priganc, PhD, OTR, CHT, CLT, Practice Forum Editor.

    The "necktie lasso" is a new technique that allows the simultaneous active treatment, of both Wartenberg's sign and claw deformity of the fifth and the fourth digits in the hand with ulnar nerve palsy. The flexor sublimis of the fourth digit is taken by a palmar approach. It is then divided into two strips up to the proximal part of the palm; The radial strip is used as a classical "direct lasso" to treat the claw deformity of the fourth digit; The ulnar strip is wound around the base of the fifth digit by a palmar and dorsal approaches at the level of the proximal phalanx, like a necktie, being medial to its radial pedicle, dorsal and superficial to its extensor apparatus, then lateral to its ulnar pedicle; It is then recovered in the palm and sutured to itself. From September 1998 to April 2003, this technique has been used in eight patients aged between 21 and 35 years old and suffering from post traumatic low ulnar nerve palsy. It was always very effective in dealing with Wartenberg's sign: the active adduction of the fifth digit appearing at the start of flexion. The claw deformity of the fourth and fifth digits was equally actively corrected. No complications are reported in this series. With a mean follow-up of 3 years there was no recurrence of any of the deformities. PMID:15484679

    Behçet's disease (BD) is a relapsing systemic inflammatory disorder of unknown etiology involving systemic vasculitis. Vasculitis in BD results from the involvement of arteries, veins and blood vessels of all sizes, which leads to the three major manifestations of this condition: venous occlusion, arterial occlusion and aneurysm formation. Therefore, whole-body vascular involvement should always be considered in BD patients. Here, we describe the first appearance of an internal carotid-posterior communicating artery aneurysm, resulting in complete oculomotor nerve palsy in a BD patient. A 44-year-old Japanese man suffered from recurrent episodes of erythema nodosum that had presented on the lower extremities for the past 2 years. His condition was diagnosed as an incomplete type of BD based on relapsing oral and genital ulcers, skin eruptions, such as erythema nodosum and folliculitis, a positive pathergy test and systemic arthralgia. Ten years after his initial clinical presentation, he had manifestations of right-sided ptosis and cyclic dull pain in his right temporal region. Magnetic resonance imaging and angiography revealed a right internal carotid artery-posterior communicating artery aneurysm. Although oculomotor nerve palsy associated with internal carotid artery-posterior communicating artery aneurysm in a BD patient has not been reported previously, our report highlights the fact that this abnormal manifestation should be considered in those with vasculo-BD.

    OBJECT Automated eye movement tracking may provide clues to nervous system function at many levels. Spatial calibration of the eye tracking device requires the subject to have relatively intact ocular motility that implies function of cranial nerves (CNs) III (oculomotor), IV (trochlear), and VI (abducent) and their associated nuclei, along with the multiple regions of the brain imparting cognition and volition. The authors have developed a technique for eye tracking that uses temporal rather than spatial calibration, enabling detection of impaired ability to move the pupil relative to normal (neurologically healthy) control volunteers. This work was performed to demonstrate that this technique may detect CN palsies related to brain compression and to provide insight into how the technique may be of value for evaluating neuropathological conditions associated with CN palsy, such as hydrocephalus or acute mass effect. METHODS The authors recorded subjects’ eye movements by using an Eyelink 1000 eye tracker sampling at 500 Hz over 200 seconds while the subject viewed a music video playing inside an aperture on a computer monitor. The aperture moved in a rectangular pattern over a fixed time period. This technique was used to assess ocular motility in 157 neurologically healthy control subjects and 12 patients with either clinical CN III or VI palsy confirmed by neuro-ophthalmological examination, or surgically treatable pathological conditions potentially impacting these nerves. The authors compared the ratio of vertical to horizontal eye movement (height/width defined as aspect ratio) in normal and test subjects. RESULTS In 157 normal controls, the aspect ratio (height/width) for the left eye had a mean value ± SD of 1.0117 ± 0.0706. For the right eye, the aspect ratio had a mean of 1.0077 ± 0.0679 in these 157 subjects. There was no difference between sexes or ages. A patient with known CN VI palsy had a significantly increased aspect ratio (1.39), whereas 2

    Background Posterior interosseous nerve (PIN) palsy may present with various symptoms, and may resemble cervical spondylosis. Case report We report about a 59-year-old patient with cervical spondylosis which delayed the diagnosis of posterior interosseous nerve (PIN) palsy due to an intermuscular lipoma. Initial right hand paraesthesias and clumsiness, together with MR findings of right C5–C6 and C6–C7 foraminal stenosis, misled the diagnostic investigation. The progressive loss of extension of all right hand fingers brought to detect a painless mass compressing the PIN. Electrophysiological studies confirmed a right radial motor neuropathy at the level of the forearm. Results Surgical tumor removal and nerve decompression resulted in a gradual motor deficits recovery. Conclusions A thorough clinical examination is paramount, and electrophysiology may differentiate between cervical and peripheral nerve lesions. Ultrasonography and MR offer an effective evaluation of lipomas, which represent a rare cause of PIN palsy. Surgical decompression and lipoma removal generally determine excellent prognoses, with very few recurrences. PMID:27142825

    Our study evaluates the grade and timing of recovery in 30 patients with complete facial paralysis (House-Brackmann grade VI) treated with hypoglossal-facial nerve (XII-VII) anastomosis and a long-term rehabilitation program, consisting of exercises in facial muscle activation mediated by tongue movement and synkinesis control with mirror feedback. Reinnervation after XII-VII anastomosis occurred in 29 patients, on average 5.4 months after surgery. Three years after the anastomosis, 23.3% of patients had grade II, 53.3% grade III, 20% grade IV and 3.3% grade VI ratings on the House-Brackmann scale. Time to reinnervation was associated with the final House-Brackmann grade. Our study demonstrates that patients undergoing XIIVII anastomosis and a long-term rehabilitation program display a significant recovery of facial symmetry and movement. The recovery continues for at Hypoglossal-facial nerve anastomosis and rehabilitation in patients with complete facial palsy: cohort study of 30 patients followed up for three years least three years after the anastomosis, meaning that prolonged follow-up of these patients is advisable.

    2016-05-01

    Accepted indications for exploration in obstetrical brachial plexus palsy (OBPP) vary by center. Most agree that full elbow flexion against gravity at nine months of age implies high chance of spontaneous recovery and thus excludes a baby from surgical intervention. However, there are certain movements of the shoulder and forearm that may not be used frequently by the infant, but are extremely important functionally as they grow. These movements are difficult to assess in a baby and may lead to some clinicians to recommend conservative treatment, when this cohort of infants may in fact benefit substantially from surgery. A retrospective review was conducted on all infants managed surgically at the Brachial Plexus Center of a major children's hospital from 2009 to 2014. Further analysis identified five patients who had near-normal AMS scores for elbow flexion but who had weakness of shoulder abduction, flexion, external rotation, and/or forearm supination. In contrast to standard conservative management, this cohort underwent exploration, C5-6 neuroma excision, and sural nerve grafting. Data analysis was performed on this group to look for overall improvement in function. During an average follow-up period of 29 months, all patients made substantial gains in motor function of the shoulder and forearm, without loss of elbow flexion or extension, or worsening of overall outcome. In select infants with brachial plexus injuries but near-normal AMS scores for elbow flexion, surgical intervention may be indicated to achieve the best functional outcome. PMID:26806089

    Background Simulation in medical education provides students with opportunities to practice interviews, examinations, and diagnosis formulation related to complex conditions without risks to patients. Aim To examine differences between individual and team participation on learning outcomes and student perspectives through use of virtual patients (VPs) for teaching cranial nerve (CN) evaluation. Methods Fifty-seven medical students were randomly assigned to complete simulation exercises either as individuals or as members of three-person teams. Students interviewed, examined, and diagnosed VPs with possible CN damage in the Neurological Exam Rehearsal Virtual Environment (NERVE). Knowledge of CN abnormalities was assessed pre- and post-simulation. Student perspectives of system usability were evaluated post-simulation. Results An aptitude-treatment interaction (ATI) effect was detected; at pre-test scores ≤50%, students in teams scored higher (83%) at post-test than did students as individuals (62%, p = 0.02). Post-simulation, students in teams reported greater confidence in their ability to diagnose CN abnormalities than did students as individuals (p = 0.02; mean rating = 4.0/5.0 and 3.4/5.0, respectively). Conclusion The ATI effect allows us to begin defining best practices for the integration of VP simulators into the medical curriculum. We are persuaded to implement future NERVE exercises with small teams of medical students. PMID:22938679

    Paralytic ectropion caused by facial nerve palsy often requires surgical intervention for cornea protection. In this study, the authors intended to investigate the long-term surgical outcome of their surgical technique of correcting paralytic ectropion, which is a combined lateral tarsal strip and minimal temporal permanent tarsorrhaphy. The authors performed a retrospective chart review of patients who underwent paralytic ectropion repair by combined lateral tarsal strip with minimal temporal permanent tarsorrhaphy (5  mm) from January 2010 to December 2012. Patients with at least 1 year of follow-up were included. An analysis of preoperative and postoperative measurements included the extent of lagophthalmos, grade of superficial punctate keratopathy (SPK), and tear break-up time (tBUT). The study included 22 patients and a total of 22 eyes. The lagophthalmos, grade of SPK, and tBUT at both 1 month and 1 year of postoperative follow-up were all significantly improved compared with preoperatively (all P < 0.01). At 1 year after surgery, the mean SPK grade and tBUT were slightly, but not significantly, worse than at 1 month after surgery (P = 0.716 and P = 0.632, retrospectively). Three patients were not satisfied with the aesthetic appearance; however, no patient required additional surgery to enhance eyelid closure because of ectropion recurrence or to reopen the tarsorrhaphy during long-term follow-up. Combined lateral tarsal strip with minimal temporal permanent tarsorrhaphy is a quick, safe, and effective surgical technique for the treatment of lower eyelid paralytic ectropion. It produces minimal cosmetic disfigurement and low morbidity during long-term follow-up. PMID:26086924

    Aims: Phrenic nerve palsy (PNP) is still a cause for concern in Cryoballoon ablation (CBA) procedures. New surveillance techniques, such as invasive registration of the compound motor action potential (CMAP), have been thought to prevent the occurrence of PNP. The present study investigates the impact of CMAP surveillance via an alternative and non-invasive ECG-conduction technique during CBA. Methods: PVI with CBA was performed in 166 patients suffering from AF. Diaphragmal contraction was monitored by abdominal hands-on observation in Observation Group I; Observation Group II was treated using additional ECG-conduction, as a means of modified CMAP surveillance method. During the ablation of the right superior and inferior pulmonary veins, the upper extremities lead I was newly adjusted between the inferior sternum and the right chest, thereby recording the maximum CMAP. The CMAP in the above-mentioned ECG leads was continuously observed in a semi-quantitative manner. Results: PNP was observed in 10 (6%) patients in total. In Observation Group I, 6 out of 61 (9.8%) demonstrated PNP. In Observation Group II a significant decrease of PNP could be demonstrated (p <0,001) and occurred in 4 out of 105 patients (3.8%). While three patients from Observation Group I left the EP lap with an ongoing PNP, none of the patients in Observation Group II had persistent PNP outside of the EP lab. Conclusion: The present study demonstrates that additional ECG-conduction, used as modified CMAP surveillance, is an easy, effective and helpful additional safety measure to prevent PNP in CBA.

    Injury to the marginal mandibular branch of the facial nerve (MMN) during surgery often results in poor functional and cosmetic outcomes. A line two finger breadths or 2 cm inferior to the border of the mandible is commonly used in planning neck incisions to avoid injury to the MMN. The purpose was to compare the two finger breadth/2 cm landmarks in predicting MMN course, and their accuracy/reliability. Thirty-one cadaveric specimens were scanned to obtain 3D surface topography (FARO® scanner). Four independent raters pinned the inferior border of the mandible and a two finger breadth line and 2cm line below. The location of each pin was digitized (Microscribe™). A preauricular flap was raised, and MMN branches were digitized and modelled (Geomagic®/Maya®) enabling quantification of the accuracy of these landmarks. The location of the two-finger breadth line was variable, spanning 25-51 mm below the inferior border of the mandible (ICC = 0.10). The most inferior MMN branch did not pass below the two-finger breadth line in any specimen, but a narrow clearance zone (≤5 mm) was found in two. In contrast, in 7/31 specimens, the most inferior MMN branch coursed below the 2 cm line and would be at risk of injury. It was concluded that an incision two finger breadths below the inferior border of the mandible could provide safer access than the 2 cm line. After an incision has been placed using the two finger-breadth landmark, caution must be exercised during dissection as branches of the MMN may lie only a few millimeters superior to the incision.

  9. Nerve Transfers for the Restoration of Wrist, Finger, and Thumb Extension After High Radial Nerve Injury.

    PubMed

    Pet, Mitchell A; Lipira, Angelo B; Ko, Jason H

    2016-05-01

    High radial nerve injury is a common pattern of peripheral nerve injury most often associated with orthopedic trauma. Nerve transfers to the wrist and finger extensors, often from the median nerve, offer several advantages when compared to nerve repair or grafting and tendon transfer. In this article, we discuss the forearm anatomy pertinent to performing these nerve transfers and review the literature surrounding nerve transfers for wrist, finger, and thumb extension. A suggested algorithm for management of acute traumatic high radial nerve palsy is offered, and our preferred surgical technique for treatment of high radial nerve palsy is provided. PMID:27094891

  10. Dynamics of abducens nucleus neurons in the awake mouse

    The mechanics of the eyeball and orbital tissues (the “ocular motor plant”) are a fundamental determinant of ocular motor signal processing. The mouse is used increasingly in ocular motor physiology, but little is known about its plant mechanics. One way to characterize the mechanics is to determine relationships between extraocular motoneuron firing and eye movement. We recorded abducens nucleus neurons in mice executing compensatory eye movements during 0.1- to 1.6-Hz oscillation in the light. We analyzed firing rates to extract eye position and eye velocity sensitivities, from which we determined time constants of a viscoelastic model of the plant. The majority of abducens neurons were already active with the eye in its central rest position, with only 6% recruited at more abducted positions. Firing rates exhibited largely linear relationships to eye movement, although there was a nonlinearity consisting of increasing modulation in proportion to eye movement as eye amplitudes became small (due to reduced stimulus amplitude or reduced alertness). Eye position and velocity sensitivities changed with stimulus frequency as expected for an ocular motor plant dominated by cascaded viscoelasticities. Transfer function poles lay at approximately 0.1 and 0.9 s. Compared with previously studied animal species, the mouse plant is stiffer than the rabbit but laxer than cat and rhesus. Differences between mouse and rabbit can be explained by scaling for eye size (allometry). Differences between the mouse and cat or rhesus can be explained by differing ocular motor repertoires of animals with and without a fovea or area centralis. PMID:22896719

    Advances in our knowledge on eye movements over the last 25 years are reviewed, focusing on the author's experience. First, the advantages of binocular frontal vision, which is a common characteristic of all predator mammals, are compared to those of lateral vision, characterizing their preys. Binocular frontal vision implies a perfect parallelism of both eyes, which is ensured in the pons by means of the abducens nucleus, controlling abduction as well as adduction. The pathological example of the "one-and-a-half" syndrome, in which the abducens nucleus and the adjacent medial longitudinal fasciculus are simultaneously impaired, is described. The main brainstem syndromes involving vertical eye movements are also reviewed: in particular, the third nerve nucleus syndrome, in which both ipsilateral third nerve paralysis and contralateral superior rectus paralysis (with hypotropia) result from a unilateral third nerve nucleus lesion. A case of upbeat nystagmus (in the primary position of gaze) due to a small upper pontine lesion, probably affecting the ventral tegmental tract (VTT) is also reported. This is an opportunity to emphasize that, although a number of cases of upbeat nystagmus due to focal brainstem lesions affecting the upward vestibular pathway (UVP)--either at the upper pontine (VTT) or caudal medullary level--exist in the literature, no convincing cases with downbeat nystagmus (in the primary position of gaze) due to a focal brainstem lesion have been reported. Downbeat nystagmus could result from a UVP hyperactivity (secondary to a floccular lesion) and the notion that this pathway is physiologically predominant compared to the downward pathway, maybe due to gravity, is developed. A new hypothesis about the role of the caudal medulla in UVP is also proposed. Next, the cortical control of saccadic eye movements is reviewed, with a reminder that reflexive saccades are mainly triggered by the parietal eye field whereas intentional saccades depend upon the

    Alpha herpes virus is the major causes of peripheral facial palsy such as Bell's palsy or Ramsay Hunt syndrome. Ramsay Hunt syndrome is caused by varicella zoster virus (VZV) infection, and can be diagnosed by facial nerve paralysis associated with herpetic eruption on the pinna, and complication of by vestibulo-cochlear dysfunction. On the other hand, Bell's palsy presents only facial palsy and its diagnosis is made by the exclusion of known conditions. The causes of Bell's palsy had been unknown for many years, however, recently it was revealed that herpes simplex type 1 was the major cause of Bell's palsy by PCR. Because early treatment with acyclovir and prednisone was proven to be effective, we should make efforts to diagnose these diseases as early as possible. PMID:10774214

    Dural venous sinus thrombosis, especially of the sigmoid sinus, is a known but uncommon intracranial extradural complication of chronic suppurative otitis media. Even rarer is the simultaneous occurrence of bilateral abducens palsy in the same patient. We report the case of an adolescent male who presented with signs of raised intracranial pressure, diplopia and bilateral lateral rectus palsy associated with a history of left ear discharge and neck swelling. Extensive dural sinus thrombosis extending right up to the left internal jugular vein was confirmed on CT imaging. The patient was successfully treated with thrombolytic agents and antibiotic therapy. The pathophysiology of the concurrent complications is discussed. PMID:23355565

    2016-06-01

    Cerebral palsy has always been known as a disorder of movement and posture resulting from a non-progressive injury to the developing brain; however, more recent definitions allow clinicians to appreciate more than just the movement disorder. Accurate classification of cerebral palsy into distribution, motor type and functional level has advanced research. It also facilitates appropriate targeting of interventions to functional level and more accurate prognosis prediction. The prevalence of cerebral palsy remains fairly static at 2-3 per 1000 live births but there have been some changes in trends for specific causal groups. Interventions for cerebral palsy have historically been medical and physically focused, often with limited evidence to support their efficacy. The use of more appropriate outcome measures encompassing quality of life and participation is helping to deliver treatments which are more meaningful for people with cerebral palsy and their carers.

    The median nerve serves a crucial role in extrinsic and intrinsic motor and sensory function to the radial half of the hand. High median nerve injuries, defined as injuries proximal to the anterior interosseous nerve origin, therefore typically result in significant functional loss prompting aggressive surgical management. Even with appropriate recognition and contemporary nerve reconstruction, however, motor and sensory recovery may be inadequate. With isolated persistent high median nerve palsies, a variety of available tendon transfers can improve key motor functions and salvage acceptable use of the hand. PMID:27387077

    Cerebral palsy is the most common cause of childhood-onset, lifelong physical disability in most countries, affecting about 1 in 500 neonates with an estimated prevalence of 17 million people worldwide. Cerebral palsy is not a disease entity in the traditional sense but a clinical description of children who share features of a non-progressive brain injury or lesion acquired during the antenatal, perinatal or early postnatal period. The clinical manifestations of cerebral palsy vary greatly in the type of movement disorder, the degree of functional ability and limitation and the affected parts of the body. There is currently no cure, but progress is being made in both the prevention and the amelioration of the brain injury. For example, administration of magnesium sulfate during premature labour and cooling of high-risk infants can reduce the rate and severity of cerebral palsy. Although the disorder affects individuals throughout their lifetime, most cerebral palsy research efforts and management strategies currently focus on the needs of children. Clinical management of children with cerebral palsy is directed towards maximizing function and participation in activities and minimizing the effects of the factors that can make the condition worse, such as epilepsy, feeding challenges, hip dislocation and scoliosis. These management strategies include enhancing neurological function during early development; managing medical co-morbidities, weakness and hypertonia; using rehabilitation technologies to enhance motor function; and preventing secondary musculoskeletal problems. Meeting the needs of people with cerebral palsy in resource-poor settings is particularly challenging. PMID:27188686

    Bell's palsy is unilateral, acute onset facial paralysis that is a common condition. One in every 65 people experiences Bell's palsy in the course of their lifetime. The majority of patients afflicted with this idiopathic disorder recover facial function. Initial treatment involves oral corticosteroids, possible antiviral drugs, and protection of the eye from desiccation. A small subset of patients may be left with incomplete recovery, synkinesis, facial contracture, or hemifacial spasm. A combination of medical and surgical treatment options exist to treat the long-term sequelae of Bell's palsy. PMID:26611696

    Predilection sites for infratentorial multiple sclerosis lesions are well known and frequently involve the fasciculus longitudinalis medialis leading to classical internuclear ophthalmoplegia. We report a very rare oculomotor disorder due to a demyelinating central nervous system (CNS) lesion in the medial part of the lower pontine tegmentum. A 36-year-old man presented with sudden onset of blurred vision. Clinically there was limited eye adduction and abduction to either side, which corresponds to bilateral horizontal gaze palsy. Brain magnetic resonance imaging (MRI) showed a demyelinating CNS lesion affecting the fasciculus longitudinalis medialis, abducens nuclei or abducens fibres in the medial part of the lower pontine tegmentum. Furthermore there were six further demyelinating white matter lesions fulfilling all Barkhof criteria for multiple sclerosis. Demyelinating CNS lesions causing isolated bilateral horizontal gaze palsy are exceptional and usually associated with further focal neurological deficits, which was not the case in the presenting patient. This is a unique video report of isolated bilateral horizontal gaze palsy as the initial manifestation of demyelinating CNS disease, which lead to definite diagnosis of relapsing remitting multiple sclerosis.

    A 61-year-old woman developed hearing difficulties and became thirsty after experiencing cold symptoms. A neurological examination revealed a loss of odor sensation, facial palsy, dysphasia, and dysarthria. Vocal cord palsy was observed during pharyngoscopy. Brain magnetic resonance imaging (MRI) showed a thickened pituitary stalk and swelling of the pituitary gland, but no high signal intensity regions were seen in the posterior portion of the pituitary gland. Gadolinium-enhanced MRI demonstrated a thickened dura mater over the anterior cranial fossa. A biopsy specimen of the thickened dura mater showed fibrosis, granulomatous inflammation, and necrotic foci. Blood tests detected myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA). The patient's urine osmolarity was low even though she exhibited hypernatremia. We diagnosed her with hypertrophic pachymeningitis associated with MPO-ANCA and diabetes insipidus. The patient received two courses of 5-day high-dose intravenous methylprednisolone (1.0 g/day), and was subsequently administered oral prednisolone, which gradually relieved her symptoms. However, the patient's symptoms recurred despite the high-dose prednisolone treatment. It was difficult to control the patient's symptoms in this case with oral prednisolone monotherapy, but combined treatment with cyclosporine resulted in sustained remission. It is considered that patients with MPO-ANCA-positive hypertrophic pachymeningitis require combination therapy with prednisolone and immunosuppressive agents at an early stage. PMID:27098904

PTA is a pathophysiology phenomenon which has been implicated as a rare cause of cranial nerve dysfunction. We report the case of a 40-year-old woman who developed a complete oculomotor nerve palsy caused by a persistent ecstatic trigeminal artery. Brain MRI and MRA studies documented a neurovascular conflict between the oculomotor nerve and a PTA.

    Fractures of the distal third of the humerus may be complicated by complete lesions of the radial nerve which may be entrapped or compressed by bone fragments. Indirect reduction and internal fixation may result in a permanent nerve lesion. We describe the treatment of these lesions by insertion of a bridge plate using the minimally-invasive percutaneous technique. Six patients were operated on and showed complete functional recovery. Healing of the fractures occurred at a mean of 2.7 months (2 to 3) and complete neurological recovery by a mean of 2.3 months (1 to 5). In one patient infection occurred which resolved after removal of the implant. PMID:17159176

    This article concludes the series on cranial nerves, with review of the final four (IX–XII). To summarize briefly, the most important and common syndrome caused by a disorder of the glossopharyngeal nerve (craniel nerve IX) is glossopharyngeal neuralgia. Also, swallowing function occasionally is compromised in a rare but disabling form of tardive dyskinesia called tardive dystonia, because the upper motor portion of the glossopharyngel nerve projects to the basal ganglia and can be affected by lesions in the basal ganglia. Vagus nerve funtion (craniel nerve X) can be compromised in schizophrenia, bulimia, obesity, and major depression. A cervical lesion to the nerve roots of the spinal accessory nerve (craniel nerve XI) can cause a cervical dystonia, which sometimes is misdiagnosed as a dyskinesia related to neuroleptic use. Finally, unilateral hypoglossal (craniel nerve XII) nerve palsy is one of the most common mononeuropathies caused by brain metastases. Supranuclear lesions of cranial nerve XII are involved in pseudobulbar palsy and ALS, and lower motor neuron lesions of cranial nerve XII can also be present in bulbar palsy and in ALS patients who also have lower motor neuron involvement. This article reviews these and other syndromes related to cranial nerves IX through XII that might be seen by psychiatry. PMID:20532157

    Radial nerve palsy typically occurs as a result of trauma or iatrogenic injury and leads to the loss of wrist extension, finger extension, thumb extension, and a reduction in grip strength. In the absence of nerve recovery, reconstruction of motor function involves tendon transfer surgery. The most common donor tendons include the pronator teres, wrist flexors, and finger flexors. The type of tendon transfer is classified based on the donor for the extensor digitorum communis. Good outcomes have been reported for most methods of radial nerve tendon transfers as is typical for positional tendon transfers not requiring significant power. PMID:27387076

  9. Common questions about Bell palsy.

    PubMed

    Albers, Janet R; Tamang, Stephen

    2014-02-01

    Bell palsy is an acute affliction of the facial nerve, resulting in sudden paralysis or weakness of the muscles on one side of the face. Testing patients with unilateral facial paralysis for diabetes mellitus or Lyme disease is not routinely recommended. Patients with Lyme disease typically present with additional manifestations, such as arthritis, rash, or facial swelling. Diabetes may be a comorbidity of Bell palsy, but testing is not needed in the absence of other indications, such as hypertension. In patients with atypical symptoms, magnetic resonance imaging with contrast enhancement can be used to rule out cranial mass effect and to add prognostic value. Steroids improve resolution of symptoms in patients with Bell palsy and remain the preferred treatment. Antiviral agents have a limited role, and may improve outcomes when combined with steroids in patients with severe symptoms. When facial paralysis is prolonged, surgery may be indicated to prevent ocular desiccation secondary to incomplete eyelid closure. Facial nerve decompression is rarely indicated or performed. Physical therapy modalities, including electrostimulation, exercise, and massage, are neither beneficial nor harmful. PMID:24506123

  10. Eye Movements and Abducens Motoneuron Behavior During Cholinergically Induced REM Sleep

    PubMed Central

    2009-01-01

    Study objectives: The injection of cholinergic drugs in the pons has been largely used to induce REM sleep as a useful model to study different processes during this period. In the present study, microinjections of carbachol in the nucleus reticularis pontis oralis (NRPO) were performed to test the hypothesis that eye movements and the behavior of extraocular motoneurons during induced REM sleep do not differ from those during spontaneous REM sleep. Methods: Six female adult cats were prepared for chronic recording of eye movements (by means of the search-coil technique) and electroencephalography, electromyography, ponto-geniculo-occipital (PGO) waves at the lateral geniculate nucleus, and identified abducens motoneuron activities after microinjections of the cholinergic agonist carbachol into the NRPO. Results: Unilateral microinjections (n = 13) of carbachol in the NRPO induced REM sleep-like periods in which the eyes performed a convergence and downward rotation interrupted by phasic complex rapid eye movements associated to PGO waves. During induced-REM sleep abducens motoneurons lost their tonic activity and eye position codification, but continued codifying eye velocity during the burst of eye movements. Conclusion: The present results show that eye movements and the underlying behavior of abducens motoneurons are very similar to those present during natural REM sleep. Thus, microinjection of carbachol seems to activate the structures responsible for the exclusive oculomotor behavior observed during REM sleep, validating this pharmacological model and enabling a more efficient exploration of phasic and tonic phenomena underlying eye movements during REM sleep.

    The ferret has become a popular model for physiological and neurodevelopmental research in the visual system. We believed it important, therefore, to study extraocular whole muscle as well as single motor unit physiology in the ferret. Using extracellular stimulation, 62 individual motor units in the ferret abducens nucleus were evaluated for their contractile characteristics. Of these motor units, 56 innervated the lateral rectus (LR) muscle alone, while 6 were split between the LR and retractor bulbi (RB) muscle slips. In addition to individual motor units, the whole LR muscle was evaluated for twitch, tetanic peak force, and fatigue. The abducens nucleus motor units showed a twitch contraction time of 15.4 ms, a mean twitch tension of 30.2 mg, and an average fusion frequency of 154 Hz. Single-unit fatigue index averaged 0.634. Whole muscle twitch contraction time was 16.7 ms with a mean twitch tension of 3.32 g. The average fatigue index of whole muscle was 0.408. The abducens nucleus was examined with horseradish peroxidase conjugated with the subunit B of cholera toxin histochemistry and found to contain an average of 183 motoneurons. Samples of LR were found to contain an average of 4,687 fibers, indicating an LR innervation ratio of 25.6:1. Compared with cat and squirrel monkeys, the ferret LR motor units contract more slowly yet more powerfully. The functional visual requirements of the ferret may explain these fundamental differences.

    The management of primary and secondary radial nerve palsy associated with humeral shaft fractures is still controversial. Radial nerve function is likely to return spontaneously after primary as well as secondary radial nerve palsy in the absence of any level of neurotmesis. Identification and protection of the radial nerve during surgery may prevent secondary nerve palsy, but is not always performed and depends on the location of the fracture, and the experience and preference of the surgeon. We report a case of a healthy 40-year-old woman, referred to our hospital with a complete radial nerve palsy and a failed plate fixation of a right humeral shaft fracture. During exploration of the radial nerve and surgical revision of the fracture, we found the nerve entrapped by the plate and partially transected by a screw. Full recovery of radial nerve function occurred after neurolysis and microscopic neurorrhaphy. PMID:24862412

With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of untreated cases. In the remainder facial nerve function will be impaired in the long term.

    Bell's palsy is defined as a peripheral facial nerve palsy, idiophatic, and sudden onset and is considered the most common cause of this pathology. It is caused by damage to cranial nerves VII, resulting in complete or partial paralysis of the facial mimic. May be associated with taste disturbances, salivation, tearing and hyperacusis. It is diagnosed after ruling out all possible etiologies, because its cause is not fully understood.Some researches shows that herpes virus may cause this type of palsy due to reactivation of the virus or by imunnomediated post-viral nerve demielinization. Physical therapy, corticosteroids and antiviral therapy have become the most widely accepted treatments for Bell's palsy. Therapy with low-level laser (LLLT) may induce the metabolism of injured nerve tissue for the production of proteins associated with its growth and to improve nerve regeneration. The success of the treatment of Bell's palsy by using laser phototherapy isolated or in association with other therapeutic approach has been reported on the literature. In most cases, the recovery occurs without uneventfully (complications), the acute illness is not associated with serious disorders. We will present a clinical approach for treating this condition.

    Among new researches bearing on cerebral palsy are the growth of brain cells in tissue cultures for experimentation; the use of polysaccharides to prevent the formation of a glial barrier to nerve growth after injury; observation of changes in reactions of neurons at various stages of development; the finding of hypernatremia and hyperchloremia in lesions of the frontal lobe and the thalamus; stimulation of cerebral blood flow by injection of sodium bicarbonate and retardation with ammonium chloride; and studies of serial sections of brains of palsied children who died. Study of development in the early months of life has made possible the detection of significant abnormalities in behavior early in life. Loss of hearing may be tested in very young children by measuring minute variations in electrical resistance of the skin upon auditory stimulation of the sympathetic nervous system. Conditions which have been described as having been confused with cerebral palsy are dislocation of a cervical vertebra, hereditary spastic paraplegia, transverse myelopathy, injury to the spinal cord or cauda equina by anomalous growths of the spine, and also encephalitis and meningitis. Sedation has proved a valuable adjunct to electroencephalographic study of cerebral palsy. Better criteria for abnormality in the young child should be determined and the application of them more clearly standardized. Simple exercises are useful for early training of palsied children to stimulate development. "Crossed laterality"-the dominant eye being contralateral to the preferred hand-has been counteracted by special training with great success in eliminating emotional and behavior problems and accelerating development.Recent studies indicate that only 50 per cent of cerebral palsy patients have normal or better intelligence. Subluxation of the hip joint, a common deformity associated with cerebral palsy, can sometimes be corrected by operation if detected at an early stage. Radical ablation of

    Purpose To investigate the correlation between gadolinium enhanced magnetic resonance image (MRI) results and surgical findings of facial nerves in Bell's palsy and Ramsay Hunt syndrome. Materials and Methods From 1995 to 2004, MRI was performed on 13 patients with Bell's palsy or Ramsay Hunt syndrome, who were offered with surgical decompression of the facial nerve through the middle cranial fossa approach. Gadolinium enhanced MRI was performed on all patients and the enhancement of the facial nerve was evaluated by radiology specialists. Operative findings including the degree of the facial nerve segment swelling were examined. Furthermore, the time interval from the onset of palsy to surgery was evaluated. Results Swelling of facial nerve segments was found in patients with enhanced facial nerves from MRI. The swelling of the facial nerve in the labyrinthine segment in particular was identified in all patients with enhanced labyrinthine segments in MRI. The intraoperative swelling of geniculate ganglion of facial nerve was found in 78% of patients with enhanced facial segment in MRI (p = 0.01). The intraoperative swelling of tympanic segment was observed from fourth to ninth weeks after the onset of palsy. Conclusion MRI enhancement of facial nerves in Bell's palsy and Ramsay Hunt syndrome is associated with the extent of intratemporal lesions of facial nerves, especially in the labyrinthine segment.

    There is growing evidence that steroids are not beneficial for treatment of paediatric patients with Bell's palsy. To investigate, we conducted a retrospective longitudinal study examining notes of 100 children, over 12 years coded for facial nerve palsy. Of the 79 diagnosed with Bell's palsy, all recovered, and for 46 patients we had data on interval from onset of symptoms to resolution (median duration in treated group = 5 weeks, range = 39; median duration in untreated group = 6 weeks, range = 11; P = .86). From our results, we conclude that all children with Bell's palsy recovered, with or without steroid treatment, with no statistically significant difference in symptoms duration. Complications of unresolved Bell's palsy can have important long-term functional and psychosocial consequences. Therefore, we need further research on use of steroids in children with complete/severe cases; it would be a shame to omit treatment due to "absence of evidence" rather than "evidence of absence."

    The term cerebral palsy (CP), is used for a great number of clinical neurological syndromes. The syndromes are characterized by having a common cause, motor defects. It is important, because they can cause a brain damage by presenting motor defects and some associated deficiencies, such as mental deficiency, epilepsy, language and visual defects and pseudobulbar paralysis, with the non-evolving fact. Some authors prefer using terms such as "non-evolving encephalopathies". In the treatment the utility of prevention programs of early stimulation and special rehabilitation methods, and treatment of associated deficiencies such as epilepsy, mental deficiency, language, audition and visual problems, and the attention deficit improve the prognosis in an important way. The prognosis depends on the severity of the disease and the associated manifestations. PMID:18422084

    Although Sir Charles Bell was the first to provide the anatomic basis for the condition that bears his name, in recent years researchers have shown that other European physicians provided earlier clinical descriptions of peripheral cranial nerve 7 palsy. In this article, we describe the history of facial distortion by Greek, Roman, and Persian physicians, culminating in Razi's detailed description in al-Hawi. Razi distinguished facial muscle spasm from paralysis, distinguished central from peripheral lesions, gave the earliest description of loss of forehead wrinkling, and gave the earliest known description of bilateral facial palsy. In doing so, he accurately described the clinical hallmarks of a condition that we recognize as Bell palsy. PMID:21747074

  3. Prognostication of Bell's palsy using transcranial magnetic stimulation.

    Transcranial magnetic stimulation (TMS) provides a method to noninvasive excitation of the facial nerve in its intracranial segment close to the internal acoustic meatus. Thus, the site of facial nerve activation with TMS is proximal to or within the site of the lesion in Bell's palsy. To evaluate the prognostic capability of TMS in unilateral Bell's palsy we examined 137 patients with this method, and compared the results with electroneuronography (ENoG). Within 0-4 days from the onset of palsy, the patients with elicitable TMS responses recovered better than those in whom TMS responses were not elicitable. If TMS was performed 5-9 days or 10-28 days after the onset of palsy, it did not provide any prognostic information. Based on amplitude side-to-side differences, ENoG did not contribute prognostic information during the first 9 days from the onset of palsy. Later on, 10-28 days after the onset of palsy, ENoG showed an increased capability to discriminate the patients with poor prognosis. Thus, elicitable facial motor response with TMS predicts good prognosis of Bell's palsy at an early stage whereas poor response with ENoG predicts less favorable prognosis at a later stage.

    Delayed facial nerve palsy following cochlear implant surgery is less documented though it poses diagnostic and therapeutic challenges. Apart from the functional, aesthetic and emotional concerns, it can raise important medico legal issues. The objectives of this study were: to report a case of delayed facial palsy following cochlear implant surgery in a patient who had positive viral antibody markers pre operatively; and to review the literature on delayed onset facial paralysis following viral reactivation and its relation to cochlear implant surgery. An extensive literature review was done using internet and medical search engines and library facilities. Important articles on the topic were identified and summarised. Data on delayed facial palsy following cochlear implant surgery were collected, constructed in a coherent way and details discussed. Postulated mechanisms of delayed facial palsy include neural oedema, vasospasm and viral reactivation. Of these, reactivation of previous herpes simplex virus infection has special significance, as many of these patients are positive for viral antibody markers. Manipulation of sensory branches of the facial nerve and chorda tympani can be a mechanism in such cases. Correlation of clinical presentation and pre operative positive viral antibody markers with positive polymerase chain reaction can be strongly suggestive of viral reactivation. It is concluded that patients with positive viral antibody markers are more susceptible to facial palsy from viral reactivation. Corticosteroids, antiviral agents and physiotherapy can be useful in producing a quicker and complete recovery. An experienced cochlear implant surgery team and pre operative radiological evaluations are mandatory to decrease the chances of direct facial nerve trauma. Proper irrigation lowers the risk of neural oedema. PMID:19194876

    Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal-dominant peripheral neuropathy characterized by recurrent isolated nerve palsies, which are precipitated by trivial compression and trauma. Although HNPP has been well-described in literature, it often goes unrecognized.

    2014-10-01

    The aim of the present study was to evaluate vestibular nerve involvement in patients with Bell's palsy with ocular and cervical vestibular evoked myogenic potentials (oVEMP and cVEMP). Ten patients who were diagnosed with Bell's palsy and ten healthy controls were included. All patients underwent VEMP recordings within 6 days after their initial presentation. Patients with Bell's palsy had greater oVEMP asymmetry ratio comparing to healthy controls (-38.4 ± 28.7 % vs -1.3 ± 19.3 %, p = 0.005). As well N10 latencies of the oVEMP response were prolonged comparing to healthy controls (11.575 vs 9.72 ms). There was no difference in cVEMP asymmetry ratio or latencies between groups. We found no correlation between House-Brackmann grading scale and oVEMP asymmetry ratio (r = 0.003, p = 0.994). There are three possible explanations for increased oVEMP amplitudes on the affected side: (1) oVEMP response on the ipsilateral eye could be contaminated by facial nerve activity (blink reflex); (2) the amplitude of N10-P33 could be affected through the stapedial reflex; and (3) increased oVEMP amplitude could be the consequence of the vestibular nerve dysfunction itself, with prolonged latencies of the N10 oVEMP further supporting this explanation. The results of this study indicate possible involvement of the superior branch of the vestibular nerve in patients with Bell's palsy. PMID:24916836

    This is a case report of 25-year old, unemployed male, admitted to hospital due to acute onset of the left foot drop, subsequent walking difficulty and numbness of the left calf and foot. Symptoms began after prolonged sleep with previous heroin abuse by sniffing. During neurological examination, mild weakness of knee flexors, moderate weakness of plantar flexors and paralysis of foot dorsiflexors, together with hypesthesia of the left calf, foot and fingers, predominantly in the innervation area of common peroneal nerve on the same side, were observed. The electrophysiologic examination revealed predominant involvement of peroneal division within the sciatic nerve, together with recorded conduction block indicating the compression as possible mechanism of nerve injury. The patient was administered corticosteroid therapy during two months, what resulted in almost complete recovery. The peculiarity of this case report is in the presence of the sciatic nerve "Saturday night palsy" with possible effect of former heroin abuse. PMID:16053177

    The "perinatal asphyxia" is regarded to be one of the causes of cerebral palsy, though in the very most of the children with cerebral palsy there is found no hypoxia during labour. It should be mentioned, that the definition of "perinatal" and "asphyxia" neither are unic nor concret. And also there is no correlation between nonreassuring fetal heart rate patterns and acidosis in fetal blood with the incidence of cerebral palsy. Numerous studies in pregnant animals failed in proving an acute intrapartal hypoxia to be the origin of the cerebral palsy. Myers (1975) describes four patterns of anatomic brain damage after different injuries. Only his so called oligo-acidotic hypoxia, which is protracted and lasts over a longer time is leading to brain injury, which can be regarded in analogy to the injury of children with cerebral palsy. Summarising the update publications about the causes of cerebral palsy and the studies in pregnant animals there is no evidence that hypoxia during labour may be the cause of cerebral palsy. There is a great probability of a pre(and post-)natal origin of brain injury (for instance a periventricular leucomalacia found after birth) which leads to cerebral palsy. Short after labour signs of a so called "asphyxia" may occur in addition to this preexisting injury and misrepresent the cause of cerebral palsy. Finally the prepartal injury may cause both: Cerebral palsy and hypoxia. PMID:9035826

    Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective, inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology.

    Diaphragmatic palsy after acute stroke is a novel clinical entity and may result in a high incidence of respiratory dysfunction and pneumonia, which especially cause greater morbidity and mortality. Generally, internal capsule and complete middle cerebral artery (MCA) infarctions are major risk-factors for developing diaphragmatic palsy. Herein, we present a case with contralateral diaphragmatic palsy after a subcortical MCA infarction without capsular involvement. Dyspnea occurred after stroke, while a chest X-ray and CT study disclosed an elevated right hemidiaphragm without significant infiltration or patch of pneumonia. A phrenic nerve conduction study showed bilateral mild prolonged onset-latency without any significant right-left difference. This suggested a lesion causing diaphragmatic palsy was not in the phrenic nerve itself, but could possibly originate from an above central location (subcortical MCA infarction). We also discussed the role of transcranial magnetic stimulation study in the survey of central pathway and demonstrated diaphragmatic palsy-related orthopnea. PMID:21365293

    Facial nerve disorders may be of sudden onset and more often of unknown etiology. Edema of the facial nerve within the fallopian canal results in Bell's palsy. This causes compression of the nerve and affects the microcirculation. Many authors have suggested treatment for facial nerve paralysis ranging from simple physiotherapy to complicated microvascular decompression. It more often results in symptoms like synkinesis and muscle spasm after the decompression surgery of the nerve because of the inability to arrange the nerve fibers within the canal. The treatment choice also depends on patient's age, extent of the nerve damage, and patient's needs and desires. Many patients who cannot be rehabilitated functionally can be treated for esthetics of the involved muscles. This case report elaborates about a patient who was rehabilitated for esthetics and to some extent for function. PMID:26538967

    2010-01-01

    Study Objectives: The aim of this work was to characterize eye movements and abducens (ABD) motoneuron behavior after cholinergic activation of the nucleus reticularis pontis caudalis (NRPC). Methods: Six female adult cats were prepared for chronic recording of eye movements (using the scleral search-coil technique), electroencephalography, electromyography, ponto-geniculo-occipital (PGO) waves in the lateral geniculate nucleus, and ABD motoneuron activities after microinjections of the cholinergic agonist carbachol into the NRPC. Results: Unilateral microinjections of carbachol in the NRPC induced tonic and phasic phenomena in the oculomotor system. Tonic effects consisted of ipsiversive rotation to the injected side, convergence, and downward rotation of the eyes. Phasic effects consisted of bursts of rhythmic rapid eye movements directed contralaterally to the injected side along with PGO-like waves in the lateral geniculate and ABD nuclei. Although tonic effects were dependent on the level of drowsiness, phasic effects were always present and appeared along with normal saccades when the animal was vigilant. ABD motoneurons showed phasic activities associated with ABD PGO-like waves during bursts of rapid eye movements, and tonic and phasic activities related to eye position and velocity during alertness. Conclusion The cholinergic activation of the NRPC induces oculomotor phenomena that are somewhat similar to those described during REM sleep. A precise comparison of the dynamics and timing of the eye movements further suggests that a temporal organization of both NRPCs is needed to reproduce the complexity of the oculomotor behavior during REM sleep.

    Cranial nerve disorders are uncommon disease conditions encountered in pediatric patients, and can be categorized as congenital, inflammatory, traumatic, or tumorous conditions that involve the cranial nerve itself or propagation of the disorder from adjacent organs. However, determination of the normal course, as well as abnormalities, of cranial nerves in pediatric patients is challenging because of the small caliber of the cranial nerve, as well as the small intracranial and skull base structures. With the help of recently developed magnetic resonance (MR) imaging techniques that provide higher spatial resolution and fast imaging techniques including three-dimensional MR images with or without the use of gadolinium contrast agent, radiologists can more easily diagnose disease conditions that involve the small cranial nerves, such as the oculomotor, abducens, facial, and hypoglossal nerves, as well as normal radiologic anatomy, even in very young children. If cranial nerve involvement is suspected, careful evaluation of the cranial nerves should include specific MR imaging protocols. Localization is an important consideration in cranial nerve imaging, and should cover entire pathways and target organs as much as possible. Therefore, radiologists should be familiar not only with the various diseases that cause cranial nerve dysfunction, and the entire course of each cranial nerve including the intra-axial nuclei and fibers, but also the technical considerations for optimal imaging of pediatric cranial nerves. In this article, we briefly review normal cranial nerve anatomy and imaging findings of various pediatric cranial nerve dysfunctions, as well as the technical considerations of pediatric cranial nerve imaging. Online supplemental material is available for this article. (©)RSNA, 2016. PMID:27399242

    A 12-month-old boy with progressive cranial nerve palsies followed by ventilatory failure demanding artificial ventilation, generalized muscle weakness, and rapid progression to death at the age of 21 months is described. The patient had normal early development and also apparently normal hearing at presentation of illness but, after 6 months of the onset of the disease, hearing loss was documented by brainstem auditory evoked potentials (BAEP). Although the initial clinical and laboratory findings of this infant could fit with the diagnosis of progressive childhood bulbar palsy or Fazio-Londe (FL) disease, the subsequent appearance of hearing loss suggests that this patient represents a case of progressive bulbar palsy with perceptive deafness or Brown-Vialetto-Van Laere (BVVL) syndrome. To our knowledge, this case of BVVL syndrome with severe clinical features and rapid deterioration leading to death is the youngest one reported in the literature. Furthermore, this case emphasizes the need for repeated auditory examinations, including the performance of BAEP in all cases, especially infants and young children with progressive bulbar palsy.

  4. Lagophthalmos after facial palsy: current therapeutic options.

    PubMed

    Vásquez, Luz María; Medel, Ramón

    2014-01-01

    As the facial nerve carries sensory, motor and parasympathetic fibres involved in facial muscle innervation, facial palsy results in functional and cosmetic impairment. It can result from a wide variety of causes like infectious processes, trauma, neoplasms, autoimmune diseases, and most commonly Bell's palsy, but it can also be of iatrogenic origin. The main ophthalmic sequel is lagophthalmos. The increased surface exposure increases the risk of keratitis, corneal ulceration, and potentially loss of vision. Treatment options are wide; some are temporary, some permanent. In addition to gold standard and traditional therapies and procedures, new options are being proposed aiming to improve not only lagophthalmos but also the quality of life of these patients.

    There are various causes of the common peroneal nerve palsy. However, common peroneal nerve palsy caused by ganglia are uncommon. We hereby present a case of a 55-year-old man with a 1 week history of foot drop and swelling in the region of the right leg. Physical examination and nerve conduction study studies confirmed a diagnosis of common peroneal nerve palsy. Magnetic resonance imaging (MRI) revealed a lobulated, elongated cystic-appearing mass anterior to the head of fibula. Surgical decompression of the nerve with removal of the mass was performed. Surgical pathology reports confirmed the diagnosis of a ganglion cyst. Findings on physical examination, nerve conduction study and MRI results of this interesting case are being discussed. We wish to highlight that even a tumour which is benign and within the nerve sheath can cause compression. PMID:22262327

    Neuropathies during pregnancy and the postpartum period are common and are usually due to compression around pregnancy and childbirth. The most common peripheral neuropathies are Bell's palsy, carpal tunnel syndrome (CTS), and lower extremity neuropathies. Although most neuropathies are usually reversible, associated disabilities or morbidities can limit functioning and require therapy. Nerve conduction study tests and imaging should only be considered if symptoms are unusual or prolonged. Some neuropathies may be associated with preeclampsia or an inherent underlying neuropathy that increases the risk of nerve injury. All neuropathies in pregnancy should be followed as some may be persistent and require follow-up. PMID:23563878

    Spastic hypertonus (muscle over-activity due to exaggerated stretch reflexes) often develops in people with stroke, cerebral palsy, multiple sclerosis and spinal cord injury. Lesioning of nerves, e.g. with phenol or botulinum toxin is widely performed to reduce spastic hypertonus. We have explored the use of direct electrical current (DC) to lesion peripheral nerves. In a series of animal experiments, DC reduced muscle force by controlled amounts and the reduction could last several months. We conclude that in some cases controlled DC lesioning may provide an effective alternative to the less controllable molecular treatments available today.

In this work, we recorded binocular eye movements by the scleral search-coil technique and the activity of identified abducens (ABD) motoneurons along the sleep–wake cycle in behaving cats. The activity of ABD motoneurons during REM sleep was characterized by a tonic decrease of their mean firing rate throughout this period, and short bursts and pauses coinciding with the occurrence of PGO waves. We demonstrate that the decrease in the mean firing discharge was due to an active inhibition of ABD motoneurons, and that the occurrence of primary and secondary PGO waves induced a pattern of simultaneous but opposed phasic activation and inhibition on each ABD nucleus. With regard to eye movements, during REM sleep ABD motoneurons failed to codify eye position as during alertness, but continued to codify eye velocity. The pattern of tonic inhibition and the phasic activations and inhibitions shown by ABD motoneurons coincide with those reported in other non-oculomotor motoneurons, indicating that the oculomotor system – contrary to what has been accepted until now – is not different from other motor systems during REM sleep, and that all motor systems are receiving similar command signals during this period.

    Cerebral palsy is the most frequent physical disability of childhood onset. Over the past four decades, prevalence has remained remarkably constant at 2 to 3 per 1,000 live births in industrialized countries. In this article I concentrate on the rehabilitation and outcome of patients with cerebral palsy. The epidemiologic, pathogenetic, and diagnostic aspects are highlighted briefly as they pertain to the planning and implementation of the rehabilitation process. PMID:1866952

    Cerebral palsy is a chronic childhood disorder that can have diverse etiologies. Injury to the developing brain that occurs either in utero or soon after birth can result in the motor, sensory, and cognitive deficits seen in cerebral palsy. Although the etiologies for cerebral palsy are variable, neuroinflammation plays a key role in the pathophysiology of the brain injury irrespective of the etiology. Currently, there is no effective cure for cerebral palsy. Nanomedicine offers a new frontier in the development of therapies for prevention and treatment of brain injury resulting in cerebral palsy. Nanomaterials such as dendrimers provide opportunities for the targeted delivery of multiple drugs that can mitigate several pathways involved in injury and can be delivered specifically to the cells that are responsible for neuroinflammation and injury. These materials also offer the opportunity to deliver agents that would promote repair and regeneration in the brain, resulting not only in attenuation of injury, but also enabling normal growth. In this review, the current advances in nanotechnology for treatment of brain injury are discussed with specific relevance to cerebral palsy. Future directions that would facilitate clinical translation in neonates and children are also addressed. PMID:24204146

    We used the allele-specific PCR-double digestion method on peripheral myelin protein 22 (PMP22) to determine duplication and deletion mutations in the proband and family members of one family with Charcot-Marie-Tooth disease type 1 and one family with hereditary neuropathy with liability to pressure palsies. The proband and one subclinical family member from the Charcot-Marie-Tooth disease type 1 family had a PMP22 gene duplication; one patient from the hereditary neuropathy with liability to pressure palsies family had a PMP22 gene deletion. Electron microscopic analysis of ultrathin sections of the superficial peroneal nerve from the two probands demonstrated demyelination and myelin sheath hyperplasia, as well as an ‘onion-like’ structure in the Charcot-Marie-Tooth disease type 1A patient. We observed an irregular thickened myelin sheath and ‘mouse-nibbled’-like changes in the patient with hereditary neuropathy with liability to pressure palsies. In the Charcot-Marie-Tooth disease type 1A patient, nerve electrophysiological examination revealed moderate-to-severe reductions in the motor and sensory conduction velocities of the bilateral median nerve, ulnar nerve, tibial nerve, and sural nerve. Moreover, the compound muscle action potential amplitude was decreased. In the patient with hereditary neuropathy with liability to pressure palsies, the nerve conduction velocity of the bilateral tibial nerve and sural nerve was moderately reduced, and the nerve conduction velocity of the median nerve and ulnar nerve of both upper extremities was slightly reduced.

    A 5-year-old child presented to us with weakness of the left upper limb since birth. With the given history of obstetric trauma and limb examination, a diagnosis of birth brachial plexus palsy was made. Brachial plexus exploration along with microsurgery was performed at the same time which included extrinsic neurolysis of the roots and trunks and nerve transfer for better shoulder external rotation and elbow flexion. Both the movements were severely restricted previously due to co-contractures with the shoulder internal rotators and triceps. The problem of birth brachial plexus palsy is proving to be a global health burden both in developed countries and in developing countries such as India. The lack of awareness among the general public and primary healthcare providers and inadequate orthopaedic and neurosurgeons trained to treat the condition have worsened the prognosis. This case lays stress on the delayed complications in birth brachial palsy and its effective management. PMID:27402656

    Intraoperative facial nerve monitoring provides a potentially useful adjunct to recent surgical advances in neurotology and neurosurgery. These measures further aid the surgeon in preserving facial nerve function by enhancing visual identification with electrical monitoring of mechanically evoked facial muscle activation. Facial nerve monitoring in neurotologic surgery may achieve the following goals: (1) early recognition of surgical trauma to the facial nerve, with immediate feedback made available to the surgeon through monitoring of mechanical activation; (2) assistance in distinguishing the facial nerve from regional cranial nerves and from adjacent soft tissue and tumor with selective electrical stimulation; (3) facilitation of tumor excision by electrical mapping of portions of tumor that are remote from the facial nerve; (4) confirmation of nerve stimulability at the completion of surgery; and (5) identification of the site and degree of neural dysfunction in patients undergoing nerve exploration for suspected facial nerve neoplasm or undergoing decompression in acute facial palsy. This paper provides an overview of intraoperative facial nerve monitoring principles and methodology and reports a recent clinical investigation that demonstrates the utility of facial nerve monitoring in translabyrinthine acoustic neuroma surgery.

  18. Treatment of peroneal nerve injuries with simultaneous tendon transfer and nerve exploration

    PubMed Central

    2014-01-01

    Background Common peroneal nerve palsy leading to foot drop is difficult to manage and has historically been treated with extended bracing with expectant waiting for return of nerve function. Peroneal nerve exploration has traditionally been avoided except in cases of known traumatic or iatrogenic injury, with tendon transfers being performed in a delayed fashion after exhausting conservative treatment. We present a new strategy for management of foot drop with nerve exploration and concomitant tendon transfer. Method We retrospectively reviewed a series of 12 patients with peroneal nerve palsies that were treated with tendon transfer from 2005 to 2011. Of these patients, seven were treated with simultaneous peroneal nerve exploration and repair at the time of tendon transfer. Results Patients with both nerve repair and tendon transfer had superior functional results with active dorsiflexion in all patients, compared to dorsiflexion in 40% of patients treated with tendon transfers alone. Additionally, 57% of patients treated with nerve repair and tendon transfer were able to achieve enough function to return to running, compared to 20% in patients with tendon transfer alone. No patient had full return of native motor function resulting in excessive dorsiflexion strength. Conclusion The results of our limited case series for this rare condition indicate that simultaneous nerve repair and tendon transfer showed no detrimental results and may provide improved function over tendon transfer alone.

    Introduction Facial paralysis is a devastating condition with profound functional, aesthetic and psychosocial consequences. Tumors within or outside the skull, Bell’s palsy and trauma are the most common causes of facial paralysis in adults. Case Presentation Our patient was a 35-year-old man with deep laceration wounds. The patient was taken to the operating room and the nerves were repaired. We observed gradual improvement of muscle performance except branches of the frontal nerve. Conclusions Complete rupture of the facial nerve is challenging and the treatment is surgery, which requires careful planning.

    CNS involvement, except classical lymphocytic meningitis, is exceptionally rare in Kawasaki disease. Herein, we report on two atypical cases of KD with cranial nerve inflammation. The first case presented supranuclear vertical palsy and the second case Bell palsy. Outcome was promptly favorable with IV immunoglobulins, with no long-term complications. No specific KD biomarkers are available and diagnosis of atypical forms is difficult. KD can mimic a systemic illness and appropriate therapy may be delayed. PMID:26141803

    Paragangliomas of the vagus nerve are uncommon vascular benign neoplasms of neuroectodermic origin. Initial clinical manifestation is usually as an asymptomatic cervical mass, although sometimes may cause lower cranial nerve palsies. These paragangliomas seldom associate to high levels of circulating catecholamines. Diagnosis is based on the clinics aided by imaging, where CT and MRI play an important role. Angiography is not only diagnostic, but it also allows preoperative embolization of the mass. Most accepted treatment is surgical removal, even though some paragangliomas are suitable for radiation therapy in very specific patients. In this paper we describe a new case of paraganglioma of the vagus nerve in a cervical location, with hypertensive episodes and high catecholamine-levels. The authors review the literature describing the clinical presentation, the diagnosis and the treatment of this rare lesion. PMID:16855784

    Intracranial arteriovenous malformations are infrequent. Advances in endovascular treatment techniques have promoted the use of endovascular embolization in management of intracranial arteriovenous malformations. Transvenous or transarterial embolization procedures are effective options in the treatment of the arteriovenous fistulas. However, complications such as cranial nerve palsies may occur. Here, we present a case of right-sided lower motor neuron facial paralysis due to embolization of an intracranial dural arteriovenous fistula that have presented with clinical findings on the left eye. Facial functions of the patient improved from total weakness to House-Brackmann grade II, following facial nerve decompression surgery. PMID:26329900

  6. Cerebral Palsy Litigation

    2015-01-01

    The cardinal driver of cerebral palsy litigation is electronic fetal monitoring, which has continued unabated for 40 years. Electronic fetal monitoring, however, is based on 19th-century childbirth myths, a virtually nonexistent scientific foundation, and has a false positive rate exceeding 99%. It has not affected the incidence of cerebral palsy. Electronic fetal monitoring has, however, increased the cesarian section rate, with the expected increase in mortality and morbidity risks to mothers and babies alike. This article explains why electronic fetal monitoring remains endorsed as efficacious in the worlds’ labor rooms and courtrooms despite being such a feeble medical modality. It also reviews the reasons professional organizations have failed to condemn the use of electronic fetal monitoring in courtrooms. The failures of tort reform, special cerebral palsy courts, and damage limits to stem the escalating litigation are discussed. Finally, the authors propose using a currently available evidence rule—the Daubert doctrine that excludes “junk science” from the courtroom—as the beginning of the end to cerebral palsy litigation and electronic fetal monitoring’s 40-year masquerade as science.

    Optic nerve hypoplasia (ONH) is a congenital anomaly of the optic disc that might result in moderate to severe vision loss in children. With a vast number of cases now being reported, the rarity of ONH is obviously now refuted. The major aspects of ophthalmic evaluation of an infant with possible ONH are visual assessment, fundus examination, and visual electrophysiology. Characteristically, the disc is small, there is a peripapillary double-ring sign, vascular tortuosity, and thinning of the nerve fiber layer. A patient with ONH should be assessed for presence of neurologic, radiologic, and endocrine associations. There may be maternal associations like premature births, fetal alcohol syndrome, maternal diabetes. Systemic associations in the child include endocrine abnormalities, developmental delay, cerebral palsy, and seizures. Besides the hypoplastic optic nerve and chiasm, neuroimaging shows abnormalities in ventricles or white- or gray-matter development, septo-optic dysplasia, hydrocephalus, and corpus callosum abnormalities. There is a greater incidence of clinical neurologic abnormalities in patients with bilateral ONH (65%) than patients with unilateral ONH. We present a review on the available literature on the same to urge caution in our clinical practice when dealing with patients with ONH. Fundus photography, ocular coherence tomography, visual field testing, color vision evaluation, neuroimaging, endocrinology consultation with or without genetic testing are helpful in the diagnosis and management of ONH.

  8. Simulated recruitment of medial rectus motoneurons by abducens internuclear neurons: synaptic specificity vs. intrinsic motoneuron properties.

    PubMed

    Dean, P

    1997-09-01

    Ocular motoneuron firing rate is linearly related to conjugate eye position with slope K above recruitment threshold theta. Within the population of ocular motoneurons K increases as theta increases. These differences in firing rate between motoneurons might be determined either by the intrinsic properties of the motoneurons, or by differences in synaptic input to them, or by a combination of the two. This question was investigated by simulating the input signal to medial rectus motoneurons (MR-MNs) from internuclear neurons of the abducens nucleus (INNs). INNs were represented as input nodes in a two-layer neural net, each with weighted connections to every output node representing an MR-MN. Individual simulated MR-MNs were assigned parameters corresponding to an intrinsic current threshold I(R) and an intrinsic frequency-current (f-I) slope gamma. Their firing rates were calculated from these parameters, together with the effective synaptic current produced by their synaptically weighted INN inputs, with the use of assumptions employed in computer simulations of spinal motoneuron pools. The experimentally observed firing rates of MR-MNs served as training data for the net. The following two training conditions were used: 1) synaptic weights were fixed and the intrinsic parameters of the MR-MNs were allowed to vary, corresponding to the situation in which each MR-MN receives a common synaptic drive and 2) intrinsic MR-MN properties were fixed and synaptic weights were allowed to vary. In each case, the varying quantities were trained with a form of gradient descent error reduction. The simulations revealed the following three problems with the common-drive model: 1) the recruitment of INNs produced nonlinear responses in MR-MNs with low thetas; 2) the range of I(R)s required to reproduce the observed range of theta were generally larger than those measured experimentally for cat ocular motoneurons; and 3) the intrinsic f-I slope gamma increased with I

    Study Design A retrospective comparative study. Purpose To clarify the risk factors related to the development of postoperative C5 palsy through radiological studies after cervical double-door laminoplasty (DDL). Overview of Literature Although postoperative C5 palsy is generally considered to be the result of damage to the nerve root or segmental spinal cord, the associated pathology remains controversial. Methods A consecutive case series of 47 patients with cervical spondylotic myelopathy treated by DDL at our institution between April 2008 and April 2015 were reviewed. Postoperative C5 palsy occurred in 5 of 47 cases after DDL. We investigated 9 radiologic factors that have been reported to be risk factors for C5 palsy in various studies, and statistically examined these between the two groups of palsy and the non-palsy patients. Results We found a significant difference between patients with and without postoperative C5 palsy with regards to the posterior shift of spinal cord at C4/5 (p=0.008). The logistic regression analyses revealed posterior shift of the spinal cord at C4/5 (odds ratio, 12.066; p=0.029; 95% confidence interval, 1.295–112.378). For the other radiologic factors, there were no statistically significant differences between the two groups. Conclusions In the present study, we showed a significant difference in the posterior shift of the spinal cord at C4/5 between the palsy and the non-palsy groups, indicating that the "tethering phenomenon" was likely a greater risk factor for postoperative C5 palsy.

    Purpose. To report the ocular findings in patients with hematopoietic malignancy with optic nerve involvement and abducens nerve palsy. Methods. The medical records of all cases of hematopoietic cancer with ophthalmic involvements seen in the Department of Ophthalmology of the National Center for Global Health and Medicine between 2009 and 2014 were reviewed. Results. Eight patients with hematopoietic cancer with optic nerve invasion or abducens nerve palsy were studied. The primary diseases were 3 cases of multiple myeloma, 1 case of acute lymphocytic leukemia, 1 case of follicular lymphoma, and 3 cases of AIDS-related lymphoma. Six cases had optic nerve invasion, 2 cases had abducens nerve palsy, and 1 case had optic nerve invasion of both eyes. The median visual acuity of eyes with optic nerve invasion was 0.885 logarithm of the minimum angle of resolution (logMAR) units. The final visual acuity of eyes with optic nerve invasion was 1.25 logMAR units, and that of those with sixth-nerve palsy was -0.1 logMAR units. Six cases died during the five-year follow-up period. An ophthalmic involvement in patients with hematopoietic cancer, especially AIDS-related lymphoma, was associated with poor prognosis. Conclusion. Because ophthalmic involvement in patients with hematopoietic malignancy has a poor prognosis, an early diagnosis of the cancers by the ophthalmologic findings by ophthalmologists could improve the prognosis.

    Introduction: Nerve entrapment while suturing a lacerated wound is a complication that is easily avoidable. We report a case low ulnar nerve palsy due to nerve entrapment while suturing a lacerated wound. Case Report: A 48 year old lady came with complaints of pain and a lacerated wound over the dorsomedial aspect of lower third of the left forearm. The lacerated wound was sutured elsewhere one week back. She had fracture of lower third of the ulna which was stabilised with plates and screws using a separate dorsal incision. She developed ulnar claw hand on the third postoperative day. Strength duration curve revealed neurotmesis of ulnar nerve. Ulnar nerve exploration was done and the nerve was found to be ligated at the site of original laceration. The ligature was released and nerve was found to be thinned out at the site. There was no neurological recovery at 5 months follow up and reconstruction procedures in form of tendon tranfer are planned for the patient. Conclusion: This is a case of iatrogenic ulnar nerve palsy which is very rare in our literature. This can be easily avoided if proper care is taken while suturing the primary laceration. A nerve can be mistakenly sutured for a bleeding vein and proper exposure while suturing will be necessary especially at areas where nerves are superficial. PMID:27298911

    This case illustrates the complexity and interrelationship of osseous pathology with peripheral nerve entrapment and neuromata. She had an iatrogenic nerve injury of a branch of the medial dorsal cutaneous nerve causing her painful scar. Secondarily, she developed an injury to her common peroneal nerve from the cast immobilization, resulting in palsy/drop foot. The tarsal tunnel entrapment was likely a sequela of the cast immobilization and chronic swelling. Her postoperative chronic pain was compounded by the failure to use grommets with the polymeric silicon (Silastic) implant at the initial surgery, leading to a breakdown of the implant with subsequent detritic synovitis.

    Facial paralysis is one of the common problem leading to facial deformation. Bell's palsy (BP) is defined as a lower motor neuron palsy of acute onset and idiopathic origin. BP is regarded as a benign common neurological disorder of unknown cause. It has an acute onset and is almost always a mononeuritis. The facial nerve is a mixed cranial nerve with a predominant motor component, which supplies all muscles concerned with unilateral facial expression. Knowledge of its course is vital for anatomic localization and clinical correlation. BP accounts for approximately 72% of facial palsies. Almost a century later, the management and etiology of BP is still a subject of controversy. Here, we present a review of literature on this neurologically significant entity. PMID:27583233

    Patients affected by facial palsy suffer from failure to fully close the eyelids; the resulting eye exposure can lead to dry eye syndrome, loss of epithelial integrity, corneal ulceration and infections. Corneal anaesthesia exacerbates risk of corneal damage in these patients. Eyelid paralysis-associated corneal lesions may induce severe visual impairment, for which the ideal treatment is corneal transplantation, a procedure contraindicated in patients with corneal sensitivity and inadequate eyelid closure. We present the case of a patient affected by unilateral facial palsy associated with corneal anaesthesia, due to seventh and fifth cranial nerve damage following homolateral eighth cranial nerve surgery. The patient underwent surgery to re-establish eyelid and corneal competence, and then received a corneal graft with consequent amelioration of visual acuity. This is the first case of associated corneal anaesthesia and facial palsy that was comprehensively treated with a set of surgical procedures, including a corneal transplant. PMID:25139921

    Purpose In this study the authors evaluate the clinical outcomes in patients with radial nerve palsy who underwent nerve transfers utilizing redundant fascicles of median nerve (innervating the flexor digitorum superficialis and flexor carpi radialis muscles) to the posterior interosseous nerve and the nerve to the extensor carpi radialis brevis. Methods A retrospective review of the clinical records of 19 patients with radial nerve injuries who underwent nerve transfer procedures using the median nerve as a donor nerve were included. All patients were evaluated using the Medical Research Council (MRC) grading system. Results The mean age of patients was 41 years (range 17 – 78 years). All patients received at least 12 months of follow-up (20.3 ± 5.8 months). Surgery was performed at a mean of 5.7 ± 1.9 months post-injury. Post-operative functional evaluation was graded according to the following scale: grades MRC 0/5 - MRC 2/5 were considered poor outcomes, while MRC of 3/5 was a fair result, MRC grade 4/5 was a good result, and grade 4+/5 was considered an excellent outcome. Seventeen patients (89%) had a complete radial nerve palsy while two patients (11%) had intact wrist extension but no finger or thumb extension. Post-operatively all patients except one had good to excellent recovery of wrist extension. Twelve patients recovered good to excellent finger and thumb extension, two patients had fair recovery, five patients had a poor recovery. Conclusions The radial nerve is a commonly injured nerve, causing significant morbidity in affected patients. The median nerve provides a reliable source of donor nerve fascicles for radial nerve reinnervation. This transfer was first performed in 1999 and evolved over the subsequent decade. The important nuances of both surgical technique and motor re-education critical for to the success of this transfer have been identified and are discussed. PMID:21168979

    Opposition is the placement of the thumb opposite the fingers into a position from which it can work. This motion requires thumb palmar abduction, flexion, and pronation, which are provided by the abductor pollicis brevis, flexor pollicis brevis (FPB), and opponens pollicis. In the setting of a median nerve palsy, this function is typically lost, although anatomic variations and the dual innervation of the FPB may prevent complete loss at times. There are multiple well described and accepted tendon transfers to restore opposition, none of which have been proven to be superior to the others. PMID:27387078

    Facial nerve neurography involving magnetic stimulation techniques can be used to assess the intracranial segment of the facial nerve and the entire facial motor pathway, as opposed to the traditional neurography, involving only extracranial electric stimulation of the nerve. Both our own experience and data published in the literature underline the value of the method in localising facial nerve dysfunction and its role in clinical diagnosis. It is non-invasive and easy to perform. Canalicular hypoexcitability has proved to be the most useful and sensitive parameter, which indicates the dysfunction of the nerve between the brain stem and the facial canal. This is an electrophysiological finding which offers for the first time positive criteria for the diagnosis of Bell's palsy. The absence of canalicular hypoexcitability practically excludes the possibility of Bell's palsy. The technique is also able to demonstrate subclinical dysfunction of the nerve, which can be of considerable help in the etiological diagnosis of facial palsies. For example, in a situation where clinically unilateral facial weakness is observed, but facial nerve neurography demonstrates bilateral involvement, etiologies other than Bell's palsy are more likely, such as Lyme's disease, Guillain-Barré syndrome, meningeal affections etc. Furthermore, the technique differentiates reliably between peripheral facial nerve lesion involving the segment in the brain stem or the segment after leaving the brainstem.

    A 34-year-old man had right infraspinatus muscle palsy and posterior aching of the shoulder caused by electromyographically confirmed suprascapular nerve entrapment. Sonography and magnetic resonance imaging revealed a cystic lesion at the spinoglenoid notch; this lesion was diagnosed as a ganglion. Operative removal led to immediate pain relief and incomplete recovery of the compressed branches of the suprascapular nerve. PMID:8742880

  4. Human Evolution: The Real Cause for Birth Palsy

    PubMed Central

    Sreekanth, R; Thomas, BP

    ABSTRACT Objective: Birth palsy, otherwise known as obstetric brachial plexus paralysis (OBPP), is a closed stretch injury to the brachial plexus of nerves during the birth process resulting in varying degree of paralysis and contractures of the upper limb. The study aimed to find out the susceptibility of humans and small-bodied primates to birth palsy. Method: A comparative study on parturition in modern humans, hominoids, hominids, small-bodied primates and great apes was done to determine if changes in the female pelvis and neonatal head and shoulder during human evolution is the real cause for OBPP. Results: During evolution, the morphology of the female pelvis and birth canal changed into a narrow and twisted one and also the size of the fetal head increased. Thus, the narrow and twisted pelvis of the mother, and the relatively large head and broad shoulders of the newborn has made the birthing process of modern human and small bodied primates a precarious fine-tuned act with a very narrow margin for error. This has necessitated proper obstetric care to reduce or even at times obviate the incidence of birth injuries like OBPP. Conclusion: Human evolution has made human babies susceptible to birth palsy and thus is the real cause of birth palsy. PMID:26624599

    After the injury of facial nerve, facial muscles are subjected to complex series of biochemical and histological changes, which lead to muscular atrophy if reinnervation is not restored. Facial palsy is very difficult to manage completely. Regardless this fact, the plan of correction has to be directed towards the following: restoration of normal function, normal facial appearance at rest, symmetry in voluntary movements as well as symmetry in involuntary and emotional movements. Static suspension methods were used in our study. All patients had unilateral complete facial nerve palsy but one female patient who experienced the palsy of frontal branch of n.facialis. This method was successfully used to lift the eyebrow, the lid and to improve lagophthalmus on the paralytic side, then the angle and paralytic part of the lip, to reinforce buccal wall of oral cavity as well as to reconstruct new nasolabial fold. The results were satisfactory and permanent. PMID:14619718

    Various therapeutic interventions have been used in the management of children with cerebral palsy. Traditional physiotherapy and occupational therapy are widely used interventions and have been shown to be of benefit in the treatment of cerebral palsy. Evidence in support of the effectiveness of the neurodevelopmental treatment is equivocal at best. There is evidence to support the use and effectiveness of neuromuscular electrical stimulation in children with cerebral palsy. The effectiveness of many other interventions used in the treatment of cerebral palsy has not been clearly established based on well-controlled trials. These include: sensory integration, body-weight support treadmill training, conductive education, constraint-induced therapy, hyperbaric oxygen therapy, and the Vojta method. This article provides an overview of salient aspects of popular interventions used in the management of children with cerebral palsy. PMID:16391455

    Abstract Iatrogenic facial nerve injury is one of the most severe complications of cochlear implantation (CI) surgery. Intraoperative facial nerve monitoring (IFNM) is used as an adjunctive modality in a variety of neurotologic surgeries. The purpose of this retrospective study was to assess whether the use of IFNM is associated with postoperative facial nerve injury during CI surgery. The medical charts of 645 patients who underwent CI from 1999 to 2014 were reviewed to identify postoperative facial nerve palsy between those who did and did not receive IFNM. Four patients (3 children and 1 adult) were found to have delayed onset facial nerve weakness. IFNM was used in 273 patients, of whom 2 had postoperative facial nerve weakness (incidence of 0.73%). The incidence of facial nerve weakness was 0.54% (2/372) in the patients who did not receive IFNM. IFNM had no significant effect on postoperative delayed facial palsy (P = 1.000). All patients completely recovered within 3 months after surgery. Interestingly, all 4 cases of facial palsy received right CI, which may be because all of the surgeons in this study used their right hand to hold the drill. When right CI surgery is performed by a right-handed surgeon, the shaft of the drill is closer to the inferior angle of the facial recess, and it is easier to place the drilling shaft against the medial boundary (facial nerve) when the facial recess is small. The facial nerve sheaths of another 3 patients were unexpectedly dissected by a diamond burr during the surgery, and the monitor sounded an alarm. None of these 3 patients developed facial palsy postoperatively. This suggests that IFNM could be used as an alarm system for mechanical compression even without current stimulation. Although there appeared to be no relationship between the use of monitoring and delayed facial nerve palsy, IFNM is of great value in the early identification of a dehiscent facial nerve and assisting in the maintenance of its integrity

    Renal cell carcinoma (RCC) has unusual presentation affecting elderly males with a smoking history. The incidence of RCC varies while the incidence of spread of RCC to the clivus is rare. The typicality of RCC presentation includes hematuria, flank pain, and a palpable flank mass; however, RCC can also present with clival metastasis. The unique path of the abducens nerve in the clivus makes it susceptible to damage in metastasis. We report a case of a 54-year-old African American female that was evaluated for back pain, weakness, numbness, and tingling of bilateral lower extremities and subsequently disconjugate gaze and diplopia. Brain MRI confirmed metastasis to the clivus. She was started on radiotherapy and was planned for chemotherapy and transfer to a nursing home. When a patient presents with sudden unusual cranial nerve pathology, the possibility of metastatic RCC should be sought. PMID:27110412

    We report a mother and son with 5th, 6th, 7th, and bulbar cranial nerve paralysis, who had two similarly affected relatives. None of them had primary skeletal defects. Twenty-six previous reports of familial cases within the heterogeneous 'Möbius spectrum of defects' were reviewed. When cranial nerve palsies were associated with a primary skeletal defect, familial transmission was not found. No recurrence was noted in 31 cases with cranial nerve palsies associated with oral abnormalities and limb defects. The term Möbius syndrome should be restricted to cases with congenital 6th and 7th nerve paralysis with skeletal defects, who have a low recurrence risk (2%). The features in an index case which may indicate a higher risk of recurrence are the absence of skeletal defects, isolated facial palsy, deafness, ophthalmoplegia, and digital contractures. A recurrence risk of 25 to 30% in these cases appears reasonable. Images PMID:1999828

    The aim of this study is to immunolocalize the aquaporin 1 water channel protein (AQP1) in Schwann cells of idiopathic facial nerve and explore its possible role during the development of facial palsy induced by herpes simplex virus type 1 (HSV-1). HSV-1 was inoculated into the surface of posterior auricle of mouse to establish a paralyzed animal model. In HSV-1-induced facial palsy mice, protein levels of AQP1 significantly increased on the 9th to 16th day after inoculation of HSV-1. The upregulation of AQP1 was closely related to the intratemporal facial nerve edema in facial nerve canal, which was also consistent with the symptom of facial palsy in mice. In a hypoxia model of Schwann cells in vitro, we found that U0126, an ERK antagonist, inhibited not only morphological changes of cultures Schwann cells but also upregulation of both AQP1 and phosphorylated ERK. Combined with increased phosphorylated ERK in HSV-1-induced facial palsy mice, we inferred that ERK MAPK pathway might also be involved in increased AQP1 in mouse model of Bell's palsy. Although the precise mechanism needs to be further explored, our findings suggest that AQP1 in Schwann cells of intratemporal facial nerve is involved in the evolution of facial palsy induced by HSV-1 and may play an important role in the pathogenesis of this disease. AQP1 might be a potential target, and the ERK antagonist U0126 could be a new drug for the treatment of HSV-1-induced Bell's palsy in an early stage. PMID:25527444

    Tomacula is a rare hereditary disease due to a deletion on chromosome 17. Clinical presentation varies but patients usually complain of recurrent paraesthesiaes and palsies related to compression or trauma of a peripheral nerve. Diagnosis is based on electrophysiological studies, nerve biopsies and genetic tests. Implications for the patient and family members are a genetic counselling and some simple preventive measures. Although there is no curative treatment for this neuropathy, surgery can be useful for decompression of nerves and neurolysis. However, the surgical act increases the risk of nerve damage. Knowing about the diagnosis can help the patient and the surgical team avoid causing lesions. PMID:17030391

Neurophysiological studies showed a mixed axonal-demyelinating sensory-motor polyneuropathy with focal slowing of conduction velocities at the common sites of entrapment. Morphological studies on sural nerve biopsy from the proband showed active axonal regeneration without typical tomacula. Molecular analysis confirmed the presence of a deletion of chromosome 17p11.2 in both patients. Our observation confirms the heterogeneity of hereditary liability to pressure palsies and the relevance of DNA testing for the diagnosis of this hereditary neuropathy. Images PMID:9391880

    A 60-year-old female presented with a carotid-cavernous fistula (CCF) manifesting as left abducens nerve palsy. Left internal carotid digital subtraction angiography showed a persistent primitive trigeminal artery (PPTA) near the CCF. Super-selective angiography showed direct shunt flow between the PPTA trunk aneurysm and the left cavernous sinus. The aneurysm was successfully occluded with detachable coils. The CCF disappeared and the PPTA was preserved. The abducens nerve paralysis had disappeared 6 months later. CCF caused by a PPTA trunk aneurysm is extremely rare. We speculate that the PPTA trunk aneurysm formed and then ruptured due to hemodynamic stress caused by hypoplasia of the basilar artery. PMID:21785245

    The treatment of infants with brachial plexus birth palsy (BPBP) continues to be a focus at Boston Children's Hospital. Over the last 15 years, there have been many developments in the treatment of infants with BPBP. Some of the greatest changes have emerged through technical advances such as the advent of distal nerve transfers to allow targeted reinnervation as well as through research to understand the pathoanatomical changes that lead to glenohumeral dysplasia and how this dysplasia can be remodeled. This review will discuss our current practice of evaluation of the infant with BPBP, techniques for microsurgical reconstruction, and prevention and treatment of secondary glenohumeral dysplasia.

    The incidence of nerve injuries among 32,637 deliveries over a period of ten years was 1.81/1000. Brachial plexus injury (1/1000) and facial nerve injury (0.74/1000) accounted for 98% of nerve injuries. Both the right and left side were involved equally. Bilateral nerve injury was not seen. Lack of antenatal care, macrosomia, abnormal presentations, and operative vaginal deliveries significantly increased the risk of nerve injuries. These babies had significantly higher incidence of meconium stained liquor and intrapartum asphyxia. Parity of the mother, gestational age and sex of the baby did not have significant role in the causation of nerve injuries. Injuries to brachial plexus and facial nerve were seen even in babies born by caesarean section, when it was performed for obstructed labour caused by cephalo-pelvic disproportion and abnormal presentations. Three babies with injuries expired and forty-three could be followed up for varying periods. None of the babies had residual defects. Detection of cephalopelvic disproportion and abnormal lie in the third trimester and their appropriate management would decrease the incidence of obstetric palsies to a significant extent.

    To clarify the part of the neuron essential for myelinated nerve conduction, the cytochemical localization of potassium ion (K+)-dependent p-nitrophenylphosphatase (K-NPPase) activity was investigated in the normal and reserpine-treated facial nerve of guinea pigs. In the normal animals, K-NPPase activity was localized to the internodal axolemma and Schmidt-Lanterman incisures. In the Ranvier nodes, enzyme activity was observed along the paranodal and nodal axolemma. In reserpinized nerves, K-NPPase activity was absent along the internodal axolemma and Schmidt-Lanterman incisures. In the Ranvier nodes, however, enzyme activity was detectable only in the nodal axolemma. The reserpinized animals demonstrated no evidence of facial palsy. Because K-NPPase is essential for nerve conduction, these results indicate that the location of enzyme activity in reserpinized animals, namely the nodal axolemma, may be of prime importance in saltatory nerve conduction.

    Bell's palsy is the most common cause of acute facial nerve paralysis. In China, Bell's palsy is frequently treated with acupuncture. However, its efficacy and underlying mechanism are still controversial. In this study, we used functional MRI to investigate the effect of acupuncture on the functional connectivity of the brain in Bell's palsy patients and healthy individuals. The patients were further grouped according to disease duration and facial motor performance. The results of resting-state functional MRI connectivity show that acupuncture induces significant connectivity changes in the primary somatosensory region of both early and late recovery groups, but no significant changes in either the healthy control group or the recovered group. In the recovery group, the changes also varied with regions and disease duration. Therefore, we propose that the effect of acupuncture stimulation may depend on the functional connectivity status of patients with Bell's palsy. PMID:25121624

    Useful diagnostic techniques for the acute phase of sciatic nerve palsy, an entrapment neuropathy, are not well established. The aim of this paper is to demonstrate the diagnostic utility of magnetic sacral motor root stimulation for sciatic nerve palsy. We analyzed the peripheral nerves innervating the abductor hallucis muscle using both electrical stimulations at the ankle and knee and magnetic stimulations at the neuro-foramina and conus medullaris levels in a patient with sciatic nerve palsy at the level of the piriformis muscle due to gluteal compression related to alcohol consumption. On the fourth day after onset, magnetic sacral motor root stimulation using a MATS coil (the MATS coil stimulation method) clearly revealed a conduction block between the knee and the sacral neuro-foramina. Two weeks after onset, needle electromyography supported the existence of the focal lesion. The MATS coil stimulation method clearly revealed a conduction block in the sciatic nerve and is therefore a useful diagnostic tool for the abnormal neurophysiological findings associated with sciatic nerve palsy even at the acute phase.

    The aim of this study is to compare laser nerve welding to microsurgical suturing of hypoglossal-facial nerve anastomosis (HFA), and a result of immediate to delayed repair, and to evaluate the effect of laser nerve welding on HFA for reanimation of facial palsy. The first group of five rats underwent immediate HFA by microsurgical suturing and the second group of five rats by CO2 laser welding. The third group of five rats underwent delayed HFA by microsurgical suturing, and the fourth group of five rats by laser nerve welding. The fifth group of five rats served as controls, with intact hypoglossal and facial nerve. In all rats of the four different treatment groups, cholera toxin B subunit (CTb) was injected in the epineurium distal to the anastomosis site on the postoperative 6th week and in the normal hypoglossal nerve in the five rats of the control group. Neurons labeled CTb of hypoglossal nuclei were positive immunohistochemically, and the numbers were counted. In the immediate HFA groups, CTb-positive neurons were 751 +/- 247 in the laser welding group (n = 5) and 888 +/- 60 in the microsurgical suturing group (n = 5). There was no significant difference (P = 0.117). In the delayed HFA groups, CTb-positive neurons were 749 +/- 54 in the laser welding group (n = 5) and 590 +/- 169 in the microsurgical suturing group (n = 5). The difference was not significant (P = 0.116). There was no significant difference between immediate and delayed anastomosis in the laser welding group (P = 0.600), but there was significance between immediate and delayed anastomosis in the microsurgical suturing group (P = 0.009). Injected CTb in intact hypoglossal neurons (n = 5) were labeled 1,003 +/- 52. No dehiscence in the laser welding site of nerve anastomosis was seen at the time of re-exploration for injection of CTb in all 10 rats. This study shows that the regeneration of anastomosed hypoglossal-facial nerve was affected similarly by laser welding and microsurgical suturing

    2007-01-01

    Background Nerve, nerve root and plexus disorders are common diseases, but little is known about familial clustering in these diseases. This is, to our knowledge, the first systematic family study carried out on these diseases. Methods Familial risks for siblings who were hospitalised for nerve, nerve root and plexus disorders in Sweden were defined. A nationwide database for neurological diseases was constructed by linking the Multigeneration Register on 0–69‐year‐old siblings to the Hospital Discharge Register covering the years 1987–2001. Standardised risk ratios (SIRs) were calculated for affected sibling pairs by comparing them with those whose siblings had no neurological disease. Results 29 686 patients, 43% men and 57% women, were diagnosed at a mean age of 37.5 years. 191 siblings were hospitalised for these disorders, giving an overall SIR of 2.59 (95% CI 1.58 to 4.22), with no sex difference. Plantar nerve mononeuritis and carpal tunnel syndrome showed the highest familial risks: 4.82 (1.08 to 16.04) and 4.08 (2.07 to 7.84), respectively. Lateral poplitean and plantar nerve neuritis preferentially affected women, with SIRs of >8; disorders of the other cranial nerves affected only men, with an SIR of >10. Concordant trigeminal neuralgia, Bell's palsy and carpal tunnel syndrome showed familial risks, but, with the exception of Bell's palsy, they also showed correlation between spouses, implying environmental sharing of risk factors. Conclusions The results cannot distinguish between inheritable or shared environmental factors, or their interactions, but they clearly show familial clustering, suggestive of multifactorial aetiology and inviting for aetiological research.

    Botulinum toxin is a natural purified protein and one of the strongest biological poisons--neurotoxin. It is produced by the bacterium Clostridium botulinum. Its medical usage started in USA in 1981 and in Europe in 1992. There are seven different immune types of the toxin: A, B, C1, D, E, F and G. Toxin types A and B are used to decrease muscular spasticity. Botulinum toxin prevents the formation of acetylcholine from cholinergic nerve tissues in muscles, which in the end irreversibly destroys neuromuscular synapses. It is called temporary local chemodenervation. It does not affect the synthesis of acetylcholine. As it affects neuromuscular bond it also affects one of the symptoms of cerebral palsy--spasticity. Decreasing the spasticity of children with cerebral palsy leads to the improvement of conscious movements, muscles are less toned, passive mobility is improved, orthosis tolerance is also improved, and the child is enabled to perform easier and better motor functions such as crawling, standing and walking. Since the action of Botulinum toxin is limited to 2-6 months, new neural collaterals are formed and neuromuscular conductivity is reestablished which in the end once again develops a muscular spasm. This leads to a conclusion that botulinum toxin should again be applied into spastic muscles. It is very important for good effect of Botulinum toxin to set the goals of the therapy in advance. The goals include improvement of a function, prevention of contractions and deformities, ease of care and decrease of pain for children with cerebral palsy. After application of botulinum toxin, it is necessary to perform adequate and intensive physical treatment with regular monitoring of effects. This work shows a case of a boy with spastic form of cerebral palsy. After being rehabilitated using Vojta therapy and Bobath concept and the conduct of certain physical procedures, botulinum toxin is administered into his lower limbs' muscles and kinesiotherapy is

    During conventional intermittent intraoperative neuromonitoring (IONM) in thyroidectomy, recurrent laryngeal nerve (RLN) injury is detected by an electromyographic (EMG) loss of signal (LOS) after the nerve dissection. Exclusive continuous monitoring during the phase of RLN dissection may be helpful in detecting adverse EMG changes earlier. A total of 208 RLNs at risk were enrolled in this study. Standardized IONM procedures were followed. We continuously stimulated the RLN at the lower exposed end with a stimulator to exclusively monitor the real-time quantitative EMG change during RLN dissection. Once the amplitude decreased by more than 50% of the initial signal, the surgical maneuver was paused and the RLN was retested every minute for 10 minutes to determine amplitude recovery before restarting the dissection. The procedure was feasible in all patients. No LOS was encountered in this study. Nineteen RLNs had an amplitude reduction of more than 50%. Eighteen nerves showed gradual amplitude recovery (16 nerves had a traction injury and two nerves had a compression injury). After 10 minutes, the recovery was complete (i.e., >90%) in eight nerves, 70-90% in seven nerves, and 50-70% in three nerves. Among these 18 nerves, only one nerve developed temporary vocal palsy because it was exposed to unavoidable repeated nerve traction after restarting the dissection. Another nerve showed no gradual recovery from thermal injury, and developed temporary vocal palsy. The temporary and permanent palsy rates were 1% and 0%, respectively. During intermittent IONM, exclusive real-time monitoring of the RLN during dissection is an effective procedure to detect an adverse EMG change, and prevent severe RLN injuries that cause LOS.

    Introduction: We present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. Materials and Methods: From 2007 to 2012, 128 parotidectomies were performed in 125 patients. Of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2). The primary endpoint was the House-Brackmann classification at 1 month and 6 months. Facial palsy was determined when the House-Brackmann grade was 3 or higher. Results: In group 1, 15 facial palsies were noted; 8 were transient and 7 were definitive. In group 2, 19 facial palsies were noted; 12 were transient and 7 were definitive. At both one and six months after parotidectomy, the rate of facial palsy in reoperation cases was significantly higher in group 1 than in group 2. Conclusion: Facial nerve monitoring is a simple, effective adjunct method that is available to surgeons to assist with the functional preservation of the facial nerve during parotid surgery. Although it does not improve the facial prognosis in first-line surgery, it does improve the facial prognosis in reoperations. PMID:27602336

    Blood vessel and nerve damage are uncommon complications in total hip arthroplasty (THA). With an incidence between 0.1 and 0.2 % in primary THA these complications are rare but can be serious with a high mortality risk. The individual risk is determined by multiple factors depending on the surgeon's skills, the number of previous surgeries and the approach itself. The anatomy of the defect is an essential risk factor. Some procedures, such as the use of screws for cup fixation are associated with a higher risk of vascular and neural damage. The acetabular quadrant system of the hip as described by Wasielewski et al. is a useful tool to visualize the neurovascular anatomy of the hip, to detect the safe zone and subsequently prevent complications. Sciatic nerve palsy after total hip replacement is the most common nerve damage followed by femoral nerve damage. Previous surgery, a posterior approach and excessive leg extension are the most common risk factors for nerve damage. In order to diagnose nerve palsy after orthopedic surgery an electromyogram can be of use to assess the extent and prognosis. This article focuses on vascular and neural complications after total hip arthroplasty and the options for diagnosis, treatment and prevention. PMID:24384891

    Primary histiocytic sarcoma (HS) of the central nervous system (CNS) is a rare haematopoietic neoplasm. The inconsistent terminology and diagnostic criteria currently used for CNS HS have complicated the appreciation of the clinical aspects of the disease. The main differential diagnoses are non-Hodgkin's lymphoma, reactive histiocytic proliferation, dendritic cell neoplasm, undifferentiated carcinoma, inflammatory pseudotumour, Rosai-Dorfman disease and abscess. The true diagnosis of CNS HS requires an extensive immunophenotypic workup using specific histiocytic markers, such as CD163, with the exclusion of markers of other cell lineages. This clinicopathological case report describes an improved approach towards the differential diagnosis of CNS HS. PMID:25123571

    2016-01-01

    Background: As an extremely rare subtype of sarcoidosis that develops exclusively in the nervous system, isolated neurosarcoidosis is difficult to diagnose. In addition, its exact clinical features are not known. Case Description: A 61-year-old man presented with right ear hearing loss, diplopia, and fever. Computed tomography (CT) and magnetic resonance imaging revealed mass lesions in the right cerebellum and left side body of the lateral ventricle. Neither systemic CT nor positron emission tomography revealed extracranial lesions. A neuroendoscopic biopsy was performed on the lateral ventricle lesion, and a histopathology analysis revealed epithelioid granulomatous inflammation. By systematic exclusion of other possible granulomatous diseases, isolated neurosarcoidosis was diagnosed. The lesions disappeared immediately upon corticosteroid (methylprednisolone) treatment and had not recurred as of a 12-month follow-up examination. Conclusions: Isolated neurosarcoidosis is difficult to diagnose. Successful diagnosis requires compatible clinical findings, histological demonstration of noncaseating granulomas, and exclusion of other granulomatous diseases. Isolated neurosarcoidosis has a relatively good clinical prognosis, which could be characteristic of the disease. PMID:27168947

    Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder, characterized by motor symptoms, postural instability, personality changes, and cognitive impairment. There is no effective treatment for this disorder. Reduced neurotransmission of GABA in the striatum and globus pallidus may contribute to the symptoms of motor and cognitive symptoms seen in PSP. Zolpidem is a GABA agonist of the benzodiazepine subreceptor BZ1. Here a nondiabetic, normotensive case of PSP is (Progressive Supranuclear Palsy) described, which showed improvement in swallowing, speech, and gaze paresis after zolpidem therapy and possible mechanism of actions are discussed. However, more trials are needed with large number of patients to confirm the effectiveness of zolpidem in progressive supranuclear palsy. PMID:23762677

    Bell palsy (BP) is the most common diagnosis in acute and chronic facial palsy. Although most patients fully recover, more than one-quarter will have residual dysfunction. Of these, nearly half will demonstrate severe limitations in facial expression. Though significant attention has been paid to acute management and prognosis, a paucity of literature exists addressing management of the long-term sequelae of BP. This article describes contemporary use of physical therapy, injectables, and static and dynamic surgical procedures in facial reanimation of acute and chronic BP. PMID:25958893

    Sciatic nerve palsy related to hip replacement surgery (HRS) is among the most common causes of sciatic neuropathies. The sciatic nerve may be injured by various different periprocedural mechanisms. The precise localization and extension of the nerve lesion, the determination of nerve continuity, lesion severity, and fascicular lesion distribution are essential for assessing the potential of spontaneous recovery and thereby avoiding delayed or inappropriate therapy. Adequate therapy is in many cases limited to conservative management, but in certain cases early surgical exploration and release of the nerve is indicated. Nerve-conduction-studies and electromyography are essential in the diagnosis of nerve injuries. In postsurgical nerve injuries, additional diagnostic imaging is important as well, in particular to detect or rule out direct mechanical compromise. Especially in the presence of metallic implants, commonly applied diagnostic imaging tests generally fail to adequately visualize nervous tissue. MRI has been deemed problematic due to implant-related artifacts after HRS. In this study, we describe for the first time the spectrum of imaging findings of Magnetic Resonance neurography (MRN) employing pulse sequences relatively insensitive to susceptibility artifacts (susceptibility insensitive MRN, siMRN) in a series of 9 patients with HRS procedure related sciatic nerve palsy. We were able to determine the localization and fascicular distribution of the sciatic nerve lesion in all 9 patients, which clearly showed on imaging predominant involvement of the peroneal more than the tibial division of the sciatic nerve. In 2 patients siMRN revealed direct mechanical compromise of the nerve by surgical material, and in one of these cases indication for surgical release of the sciatic nerve was based on siMRN. Thus, in selected cases of HRS related neuropathies, especially when surgical exploration of the nerve is considered, siMRN, with its potential to largely

    Sympathetic nerve fibers in the skin nerves are connected with vasomotor, thermoregulatory, sensory input modulatory, and immunologic events; however, to our knowledge, no histological information is available for skin nerves in the human face. Using specimens from 17 donated cadavers (mean age, 86 years), we measured a sectional area of tyrosine hydroxylase (TH)-positive fibers in (1) the frontal nerve (V1), (2) the infraorbital nerve (V2), (3) the mental nerve (V3), (4) the greater auricular nerve (C2), (5) the auriculotemporal nerve (ATN), and (6) the zygomatic branch of the facial nerve (VII). The V1, V2, and V3 were obtained at their entrances to the subcutaneous tissue from the bony canal or notch. The V1, C2, ATN, and/or VII usually contained abundant TH-positive fibers (almost 3%-8% of the nerve sectional area), whereas the V2 and V3 consistently carried few TH-positive fibers (<1%). The difference between these two groups was quite significant (P < 0.001). Thus, from the superior cervical ganglion, the sympathetic nerve fibers reached the forehead through the frontal nerve trunk, whereas artery-bounded fibers came to the cheek, nose, and mouth. The sympathetic palsy caused by trigeminal nerve involvement is mainly characterized by the symptoms seen in the distribution of the ophthalmic division of the trigeminal nerve, such as in Horner's syndrome. It suggests that the forehead and the other facial areas are representative parts of those different sympathetic innervations that could be useful for evaluating the sympathetic function of the face in various diseases.

    Cerebral palsy (CP), the most common major disabling motor disorder of childhood, is frequently thought of as a condition that affects only children. Deaths in children with CP, never common, have in recent years become very rare, unless the child is very severely and multiply disabled. Thus, virtually all children assigned the diagnosis of CP will survive into adulthood. Attention to the adult with CP has been sparse, and the evolution of the motor disorder as the individual moves through adolescence, young adulthood, middle age, and old age is not well understood. Nor do we know what happens to other functional domains, such as communication and eating behavior, in adults with CP. Although the brain injury that initially causes CP by definition does not progressively worsen through the lifetime, the effects of CP manifest differently throughout the life span. The aging process must inevitably interact with the motor disorder, but we lack systematic, large-scale follow-up studies of children with CP into adulthood and through adulthood with thorough assessments performed over time. In this paper we summarize what is known of the epidemiology of CP throughout the life span, beginning with mortality and life expectancy, then survey what is known of functioning, ability, and quality of life of adults with CP. We conclude by describing a framework for future research on CP and aging that is built around the World Health Organization's International Classification of Functioning, Disability, and Health (ICF) and suggest specific tools and approaches for conducting that research in a sound manner.

    Peripheral facial nerve paralysis in children might be an alarming sign of serious disease such as malignancy, systemic disease, congenital anomalies, trauma, infection, middle ear surgery, and hypertension. The cases of 40 consecutive children and adolescents who were diagnosed with peripheral facial nerve paralysis at Baskent University Adana Hospital Pediatrics and Pediatric Neurology Unit between January 2010 and January 2013 were retrospectively evaluated. We determined that the most common cause was Bell palsy, followed by infection, tumor lesion, and suspected chemotherapy toxicity. We noted that younger patients had generally poorer outcome than older patients regardless of disease etiology. Peripheral facial nerve paralysis has been reported in many countries in America and Europe; however, knowledge about its clinical features, microbiology, neuroimaging, and treatment in Turkey is incomplete. The present study demonstrated that Bell palsy and infection were the most common etiologies of peripheral facial nerve paralysis. PMID:24810082

    Whiplash injuries from motor vehicle accidents are very common. The usual presentation and course of this condition normally results in resolution of symptoms within a few weeks. Brachial plexus traction injuries without any bone or joint lesion of the cervical spine have been reported before. We report a case where a gentleman was involved in a rear end vehicle collision, sustained a whiplash injury and was later found to have a long thoracic nerve palsy and spinal accessory nerve palsy. Although isolated injuries of both nerves following a whiplash injury have been reported, combined injury of the two nerves following a whiplash injury is very uncommon and is being reported for the first time.

    A palsy of the brachial plexus elements caused by carrying a heavy backpack is a very rare injury usually occurring in soldiers or hikers, and recovery is usually spontaneous. We describe here the case of male civilian presenting with an isolated serious axillary nerve palsy associated with chronic backpack use. During the surgery, a dumbbell-shaped neuroma-in-continuity was found which was caused by direct pressure from the subscapular artery. After resection of the neuroma, a nerve graft from the sural nerve was used to reconstruct the nerve. Reinnervation was successful and the patient was able to abduct his arm to its full range, with full muscle strength, within 24 months. PMID:23696291

    Bell's palsy is the most common cause of facial paralysis. Although it has been associated with diabetes mellitus, hypertension, pregnancy, and preeclampsia, the etiology of Bell's palsy remains unknown. The reactivation of latent herpes simplex virus (HSV) or varicella-zoster virus (VZV) with subsequent inflammation and entrapment of the facial nerve in the narrow labyrinthine segment has been implicated as a cause of facial paralysis, but the active role of these viruses in Bell's palsy is still discussed. This study quantified HSV-1 DNA, VZV DNA, and HHV-6 DNA in 95 saliva samples collected from patients within 48 hr from the onset of paralysis. HSV-1, VZV, and HHV-6 were detected in 13%, 3%, and 61% of patients, respectively. The detection rate did not differ significantly between patients and a control group of healthy donors. Interestingly, however, the value of HHV-6 DNA copies was significantly higher than that detected in healthy donors. In addition, the mean value of HHV-6 DNA recorded in patients who had at least a one grade improvement of palsy at the first visit was significantly lower than that detected in patients who showed no change in facial palsy grade or an increase of at least one grade. These findings call into question the role of HSV-1 and VZV in the etiology of Bell's palsy, and suggest that HHV-6 may be involved in the development of the disease or that the underlying disease mechanism might predispose patients to HHV-6 reactivation.

    In hereditary neuropathy with liability to pressure palsies (HNPP), the increase in distal motor latencies (DMLs) is often out of proportion to the slowing of conduction velocities, but the pathophysiological mechanism is still unclear. We used a combined electrophysiological and ultrasonographic (US) approach to provide insight into this issue. Twelve HNPP subjects underwent extensive electrophysiological studies and US measurements of the cross-sectional area (CSA) of several peripheral nerves. US nerve enlargement was only observed in the carpal tunnel, Guyon's canal, the elbow and the fibular head. We did not observe US abnormalities at sites where nerve entrapment is uncommon. An increase in DMLs was observed regardless of US nerve enlargement. The increased nerve CSA only in common sites of entrapment likely reflected the well-documented nerve vulnerability to mechanical stress in HNPP. No morphometric changes were seen in the distal nerve segments where compression/entrapment is unlikely, despite the fact that the DMLs were increased. These data suggest that factors other than mechanical stress are responsible for the distal slowing of action potential propagation. We speculate that a mixture of mechanical insults and an axon-initiated process in the distal nerves underlies the distal slowing and/or conduction failure in HNPP. PMID:23279340

    1997-07-01

    Hypoglossal reinnervation of the facial nerve may be required after a proximal facial nerve injury. The classic hypoglossal-facial graft procedure involves transection of the donor hypoglossal nerve, resulting in hemiglottic paralysis that, in association with paralysis of other cranial nerves, may cause speech and swallowing difficulties. Multiple lower cranial nerve palsies in conjunction with facial paralysis, as may occur after procedures such as skull base surgery, contraindicate the use of such techniques. The successful use of XII-VII "interposition jump grafts" without hemiglossal weakness has been described However, a prolonged recovery period and weaker facial reanimation have been seen. In order to attain maximum facial reinnervation while preserving hypoglossal function, we have developed a new technique of XII-VII repair. This method involves mobilization of the intratemporal portion of the facial nerve remnant, achieving a single anastomosis with the hypoglossal nerve, which has been partially incised. This technique has been used in three patients to date, with 6 to 11 months follow-up. In all cases facial tone and symmetry have been restored and voluntary facial expression accomplished. The authors conclude that by employing the techniques described highly satisfactory cosmetic and functional results may be expected, without compromising hypoglossal nerve function. PMID:9217143

    Hereditary neuropathy with liability to pressure palsy is characterized by acute, painless, recurrent mononeuropathies secondary to minor trauma or compression. A 16-year-old boy had the first episode of right foot drop after minor motorcycle accident. Electromyography revealed conduction block and slowing velocity conduction of the right deep peroneal nerve at the fibular head. After motor rehabilitation, he fully recovered. Six months later he had the second episode of foot drop in the opposite site after prolonged squatting position. Electromyography revealed sensorimotor polyneuropathy of left peroneal, sural, posterior tibial, and deep peroneal nerves and also of ulnar, radial, and median nerves of both upper limbs. Histological examination revealed sensory nerve demyelination and focal thickenings of myelin fibers. The diagnosis of hereditary neuropathy with liability to pressure palsy was confirmed by PMP22 deletion of chromosome 17p11.2. He started motor rehabilitation and avoidance of stressing factors with progressive recovery. After one-year followup, he was completely asymptomatic. Recurrent bilateral foot drop history, “sausage-like” swellings of myelin in histological examination, and the results of electromyography led the authors to consider the diagnosis despite negative family history. The authors highlight this rare disease in pediatric population and the importance of high index of clinical suspicion for its diagnosis. PMID:24251057

    Backpack palsy is a well-recognised, albeit rare, complication of carrying backpacks. Although it has been mostly described in cadets during strenuous training, sporadic cases of brachial nerve impairment have been reported in children and young adults. Here we reported the case of a 15-year-old girl who presented with a left-side brachial palsy with axonal denervation of C5C7 motor roots following a school challenge for the Duke of Edinburgh Award. Her symptoms began soon after starting the challenge and included weakness of shoulder abduction and elevation, as well as forearm, wrist and fingers extension. After 6 months of physiotherapy her motor function was completely restored. Backpack palsy can sometimes present in children and young adults. This disorder should be taken in consideration when planning for daily, as well as more challenging, physical activities in these age groups. PMID:27252125

    Objective To compare the chronological age and bone age among cerebral palsy patients in the outpatient clinic and its correlation with the type of neurological involvement, gender and functional status. Methods 401 patients with spastic cerebral palsy, and ages ranging from three months to 20 years old, submitted to radiological examination for bone age and analyzed by two independent observers according Greulich & Pyle. Results In the topographic distribution, there was a significant delay (p<0.005) in tetraparetic (17.7 months), hemiparetic (10.1 months), and diparetic patients (7.9 months). In the hemiparetic group, the mean bone age in the affected side was 96.88 months and the uncompromised side was 101.13 months (p<0.005). Regarding functional status, the ambulatory group showed a delay of 18.73 months in bone age (p<0.005). Comparing bone age between genders, it was observed a greater delay in males (13.59 months) than in females (9.63 months), but not statistically significant (p = 0.54). Conclusion There is a delay in bone age compared to chronological age influenced by the topography of spasticity, functional level and gender in patients with cerebral palsy.

    Hereditary Neuropathy with Liability to Pressure Palsy (HNPP) is a rare condition in childhood with a diverse range of clinical presentations. We analyzed the clinical presentation and electrophysiological data of 12 children with a confirmed PMP22 gene deletion and reviewed the published reports of HNPP in children and compared our data with the reports from the literature review. Peroneal palsy was the most common presentation (42%) followed by brachial plexus palsy in 25% of our cases. Nerve conduction studies were always suggestive of the diagnosis demonstrating 3 major patterns: multifocal demyelination at the area of entrapment, generalized sensory-motor polyneuropathy and a combination of the two first patterns in a vast majority (60%). Surprisingly, there was bilateral or unilateral electrophysiological entrapment of the median nerve at the carpal tunnel in all our patients. The clinical presentation of HNPP in childhood is heterogeneous and electrophysiological findings are helpful in establishing the diagnosis. Any unexplained mononeuropathy or multifocal neuropathy should lead to PMP22 gene testing to look for the deletion. Early diagnosis is important in order to facilitate appropriate genetic counseling and also for the appropriate care for these patients. PMID:26189194

    The American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) has published a supplement to this issue featuring the new Clinical Practice Guideline: Bell's Palsy. To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 11 recommendations developed encourage accurate and efficient diagnosis and treatment and, when applicable, facilitate patient follow-up to address the management of long-term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. There are myriad treatment options for Bell's palsy; some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, there are numerous diagnostic tests available that are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have an unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. PMID:24190889

    2014-01-01

    Genetic factors may be learnt from families with gene mutations that render nerve-injury susceptibility even to ordinary physical activities. A typical example is hereditary neuropathy with liability to pressure palsies (HNPP). HNPP is caused by a heterozygous deletion of PMP22 gene. PMP22 deficiency disrupts myelin junctions (such as tight junction and adherens junctions), leading to abnormally increased myelin permeability that explains the nerve susceptibility to injury. This finding should motivate investigators to identify additional genetic factors contributing to nerve vulnerability of injury. PMID:25374586

    In this study we evaluate the postoperative facial nerve function after vestibular schwannoma (VS) surgery and analyze the factors that cause it. We included 97 consecutive patients undergoing surgical excision of sporadic unilateral VS. Patient and tumor characteristics, surgical approaches, facial nerve function, extent of tumor removal, perioperative complications are all analyzed through standardized systems. Four different surgical approaches are used: translabyrinthine, retrolabyrinthine, retrosigmoid, and middle cranial fossa. Anatomic preservation of the facial nerve is achieved in 97% of patients. The incidence of postoperative facial palsy is found to be statistically correlated to tumor size, but not to the surgical approach used and to extent of tumor penetration in the internal auditory canal. A significant improvement of the short-term facial nerve outcome is detected in patients undergone simultaneous intraoperative electromyography (EMG) and pneumatic facial nerve monitoring. Complete tumor excision is achieved in 94% of cases. Complication rates are excellent and no deaths are reported. Short- and long-term facial nerve outcome is good and comparable with those of other series reported in literature. In VS surgery both EMG and pneumatic facial nerve monitors should be simultaneously used. Further investigations are desirable to improve the facial outcome respecting the oncological radicality.

    OBJECT Results of radial nerve grafting are largely unknown for lesions of the radial nerve that occur proximal to the humerus, including those within the posterior cord. METHODS The authors describe 13 patients with proximal radial nerve injuries who were surgically treated and then followed for at least 24 months. The patients' average age was 26 years and the average time between accident and surgery was 6 months. Sural nerve graft length averaged 12 cm. Recovery was scored according to the British Medical Research Council (BMRC) scale, which ranges from M0 to M5 (normal muscle strength). RESULTS After grafting, all 7 patients with an elbow extension palsy recovered elbow extension, scoring M4. Six of the 13 recovered M4 wrist extension, 6 had M3, and 1 had M2. Thumb and finger extension was scored M4 in 3 patients, M3 in 2, M2 in 2, and M0 in 6. CONCLUSIONS The authors consider levels of strength of M4 for elbow and wrist extension and M3 for thumb and finger extension to be good results. Based on these criteria, overall good results were obtained in only 5 of the 13 patients. In proximal radial nerve lesions, the authors now advocate combining nerve grafts with nerve or tendon transfers to reconstruct wrist, thumb, and finger extension. PMID:26274998

    Objectives. Although hereditary neuropathy with liability to pressure palsies (HNPP) presents with a distinct phenotype on history, clinical exam, and nerve conduction studies, it may be masked if diagnostic work-up suggests other causes. Case Report. In a 37-year-old male with pseudoradicular lumbar pain, neurological exam revealed sore neck muscles, peripheral facial nerve palsy, right anacusis and left hypoacusis, hemihypesthesia of the right face, mild distal quadriparesis, diffuse wasting, and generally reduced tendon reflexes. He had a history of skull fracture due to a gunshot behind the right ear and tuberculosis for which he had received adequate treatment for 3 years; MRI revealed a disc prolapse at C6/7 and Th11/12. Nerve conduction studies were indicative of demyelinating polyneuropathy with conduction blocks. Despite elevated antinuclear antibodies and elevated CSF-protein, HNPP was diagnosed genetically after having excluded vasculitis, CIDP, radiculopathy, and the side effects of antituberculous treatment. Conclusions. HNPP may manifest with mild, painless, distal quadriparesis. The diagnosis of HNPP may be blurred by a history of tuberculosis, tuberculostatic treatment, hepatitis, and the presence of elevated CSF-protein. PMID:26640726

    Summary A 38-year-old woman developed bilateral carotid cavernous fistulae (CCF) following a motor vehicle collision. Her initial ophthalmologic findings included periorbital edema, palsies of the left oculomotor and abducens nerves, and residual dilated pupils. She subsequently developed significant optic disc edema and retinal vascular dilation bilaterally. Patients with similar injuries typically require neurosurgical or vascular intervention. In this case, the patient’s signs resolved spontaneously by 21 months after onset, leaving no residual ocular deficits. PMID:24109248

    This study quantified the lifetime costs of cerebral palsy (CP) in a register-based setting. It was the first study outside the US to assess the lifetime costs of CP. The lifetime costs attributable to CP were divided into three categories: health care costs, productivity costs, and social costs. The population analysed was retrieved from the Danish Cerebral Palsy Register, which covers the eastern part of the country and has registered about half of the Danish population of individuals with CP since 1950. For this study we analysed 2367 individuals with CP, who were born in 1930 to 2000 and were alive in 2000. The prevalence of CP in eastern Denmark was approximately 1.7 per 1000. Information on productivity and the use of health care was retrieved from registers. The lifetime cost of CP was about 860,000 euro for men and about 800,000 euro for women. The largest component was social care costs, particularly during childhood. A sensitivity analysis found that alterations in social care costs had a small effect, whereas lowering the discount rate from 5 to 3 per cent markedly increased total lifetime costs. Discounting decreases the value of costs in the future compared with the present. The high social care costs and productivity costs associated with CP point to a potential gain from labour market interventions that benefit individuals with CP. PMID:19416329

    Patients with hereditary neuropathy with liability to pressure palsy (HNPP) typically present with a mononeuropathy (particularly peroneal or ulnar palsy) or a brachial plexopathy. Careful electrodiagnostic testing has an important role in establishing the diagnosis of HNPP differentiating this condition from other inherited or acquired neuropathies as well as obviating the need for unnecessary surgeries. We present a case of a patient who presented with a painless brachial plexopathy who was found to have multiple sites of segmental demyelination on nerve conduction studies, consistent with HNPP. We review the clinical and electrodiagnostic features of HNPP including the key electrodiagnostic findings to screen for this disorder. PMID:21988036

    The clinical and laboratory findings are presented of 14 patients who were recently found to have an obscure form of ocular palsy during a three year study in Singapore. The disease, which has no predilection for any age groups, races, occupations, or sex, often manifests with acute onset of unilateral or bilateral cranial nerve paralysis involving the 3rd, 4th, 6th, first two branches of the 5th, and sometimes, the 2nd cranial nerve in various combinations. Major symptoms were diplopia, ptosis, giddiness, headache, facial numbness, proptosis, retro-orbital pain, chemosis, conjunctival irritation, blurred vision, and/or progressive blindness. Systemic complications were rare. Except for a raised erythrocyte sedimentation rate during the acute phase, exhaustive investigations—but short of a surgical exploration—were essentially noncontributory. All cleared up within two to four weeks, nine patients had spontaneous remission, while five improved only after a course of systemic corticosteroids. Two cases were left with some residual neurological deficits and one in this series had a relapse two years later. The relationship of this condition to those described outside South East Asia is discussed.

    ABSTRACT Cerebral palsy refers to a lesion on an immature brain, that determines permanent neurological disorders. Knowing the exact cause of the disease does not alter the treatment management. The etiology is 2-2.5/1000 births and the rate is constant in the last 40-50 years because advances in medical technologies have permitted the survival of smaller and premature new born children. Gait analysis has four directions: kinematics (represents body movements analysis without calculating the forces), kinetics (represents body moments and forces), energy consumption (measured by oximetry), and neuromuscular activity (measured by EMG). Gait analysis can observe specific deviations in a patient, allowing us to be more accurate in motor diagnoses and treatment solutions: surgery intervention, botulinum toxin injection, use of orthosis, physical kinetic therapy, oral medications, baclofen pump.

    2015-01-01

    Progressive supranuclear palsy (PSP) is a neurodegenerative syndrome that is clinically characterized by progressive postural instability, supranuclear gaze palsy, parkinsonism and cognitive decline. Pathologically, diagnosis of PSP is based on characteristic features, such as neurofibrillary tangles, neutrophil threads, tau-positive astrocytes and their processes in basal ganglia and brainstem, and the accumulation of 4 repeat tau protein. PSP is generally recognized as a sporadic disorder; however, understanding of genetic background of PSP has been expanding rapidly. Here we review relevant publications to outline the genetics of PSP. Although only small number of familial PSP cases have been reported, the recognition of familial PSP has been increasing. In some familial cases of clinically probable PSP, PSP pathologies were confirmed based on NINDS neuropathological diagnostic criteria. Several mutations in MAPT, the gene that causes a form of familial frontotemporal lobar degeneration with tauopathy, have been identified in both sporadic and familial PSP cases. The H1 haplotype of MAPT is a risk haplotype for PSP, and within H1, a sub-haplotype (H1c) is associated with PSP. A recent genome-wide association study on autopsyproven PSP revealed additional PSP risk alleles in STX6 and EIF2AK3. Several heredodegenerative parkinsonian disorders are referred to as PSP-look-alikes because their clinical phenotype, but not their pathology, mimics PSP. Due to the fast development of genomics and bioinformatics, more genetic factors related to PSP are expected to be discovered. Undoubtedly, these studies will provide a better understanding of the pathogenesis of PSP and clues for developing therapeutic strategies. PMID:26413239

    Reverse open shoulder arthroplasty requires a comprehensive analgesic plan involving regional anesthesia. The commonly performed interscalene brachial plexus blockade confers a high likelihood of diaphragmatic paralysis via phrenic nerve palsy, making this option riskier in patients with limited pulmonary reserve. Continuous blockade of the suprascapular nerve, a more distal branch of the C5 and C6 nerve roots, may be a viable alternative. We report a successful case of the use of a suprascapular nerve block with continuous programmed intermittent bolus perineural analgesia in a patient with severe chronic obstructive pulmonary disease who underwent reverse open shoulder arthroplasty.

    Leprosy neuropathy is dependent on the patient's immune response and expresses itself as a focal or multifocal neuropathy with asymmetric involvement. Leprosy neuropathy evolves chronically but recurrently develops periods of exacerbation during type 1 or type 2 reactions, leading to acute neuropathy. Nerve enlargement leading to entrapment syndromes is also a common manifestation. Pain may be either of inflammatory or neuropathic origin. A thorough and detailed evaluation is mandatory for adequate patient follow-up, including nerve palpation, pain assessment, graded sensory mapping, muscle power testing, and autonomic evaluation. Nerve conduction studies are a sensitive tool for nerve dysfunction, including new lesions during reaction periods or development of entrapment syndromes. Nerve ultrasonography is also a very promising method for nerve evaluation in leprosy. The authors propose a composite nerve clinical score for nerve function assessment that can be useful for longitudinal evaluation. PMID:26773623

    The Bell's palsy (G51) consists of a unilateral face paralysis that sudden begins with unknown cause and can result in complete mimic loss or partial paralysis of the face. Damage to the VII cranial nerve can be found in the pathology, promoting mussel's inactivity. The light Photobiomodulation (LPBM) has presented ability of rush the tissue repair, favoring the regeneration of neural structures. The present study aimed to assess the effectiveness use of the 780nm laser and 850nm LED (light-emitting diode) in the treatment of the face paralysis. Were evaluated 14 patients that suffer of Bell's palsy whom were submitted to the light administration, on the Laser Clinic of the UFBA between 2005 and 2010. The treatment was performed by infrared Laser in 11 patients (78.57%), and by LED in 3 patients (21.42%). At the end of the 12 sections, 11 patients (78.57%) had presented themselves cure or with substantial improvement of the initial picture, however 3 patients (21.42%) dealt with infra-red Laser λ780nm had not evolution. The light presented as an effective method for the treatment of Bell's palsy, but the association with the physiotherapy and medications is important.

    Bell's palsy (BP), a unilateral and idiopathic palsy of the facial nerve, is a common disorder generally followed by a good natural recovery. The aim of this study was to investigate the relationship between the functional connectivity of the anterior cingulate cortex (ACC) and the recovery process of BP. Thirty-seven healthy volunteers and 67 patients were studied by functional MRI (fMRI). The seed regions of bilateral ACC were first extracted from the task-state fMRI data of healthy participants performing the task of mouth opening and closing. The connectivity of bilateral ACC was calculated from resting-state fMRI data of patients in whom only resting-state fMRI data were collected. The correlation between the strength of ACC's connectivity with the duration (time course of disease) was computed by analysis of covariance. It was found that the functional connectivity of the ACC ipsilateral to the lesioned side was enforced as the duration increased. The enforced brain areas included the sensorimotor areas and the ACC contralateral to the palsy. It was suggested that enforced functional connectivity of ACC might be related to cortical reorganization, which is important in the process of BP recovery. PMID:25426823

    Granulomatosis with polyangiitis (GPA) is an autoimmune systemic necrotizing small-vessel vasculitis associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCA). Oto-neurological manifestations of ANCA-associated vasculitis according to PR3-ANCA positivity and MPO-ANCA positivity are usually reported. Facial nerve palsy is usually reported during the clinical course of the disease but it might appear as the presenting sign of GPA. Necrotizing vasculitis of the facial nerve 'vasa nervorum' is nowadays the most widely accepted etiopathogenetic theory to explain facial damage in GPA patients. A central role for PR3-ANCA in the pathophysiology of vasculitis in GPA patients with oto-neurological manifestation is reported. GPA requires prompt, effective management of the acute and chronic manifestations. Once the diagnosis of GPA has been established, clinicians should devise an appropriate treatment strategy for each individual patient, based on current clinical evidence, treatment guidelines and recommendations.

    Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal-dominant disorder associated with recurrent mononeuropathies following compression or trivial trauma. Reports on sciatic neuropathy as the presenting manifestation of HNPP are very scarce. We report on a 21-year-old previously healthy man who was admitted with sensorimotor deficits in his left leg. He had no history of preceding transient episodes of weakness or sensory loss. Clinical and electrophysiological examinations were consistent with sciatic neuropathy. Cerebrospinal fluid investigation and MRI of the nerve roots, plexus, and sciatic nerve did not indicate the underlying aetiology. When extended electrophysiological tests revealed multiple subclinical compression neuropathies in the upper limbs, HNPP was contemplated and eventually confirmed by genetic testing. PMID:25326571

    Peripheral nerve lesions are one of the most frequent causes of chronic incapacity. Upper or lower limb palsies due to brachial or lumbar plexus injuries, facial paralysis and nerve lesions caused by systemic diseases are one of the major goals of plastic and reconstructive surgery. However, the poor results obtained in repaired peripheral nerves during the Second World War lead to a pessimist vision of peripheral nerve repair. Nevertheless, a well understanding of microsurgical principles in reconstruction and molecular biology of nerve regeneration have improved the clinical results. Thus, although the results obtained are quite far from perfect, these procedures give to patients a hope in the recuperation of their lesions and then on function. Technical aspects in nerve repair are well established; the next step is to manipulate the biology. In this article we will comment the biological processes which appear in peripheral nerve regeneration, we will establish the main concepts on peripheral nerve repair applied in facial paralysis cases and, finally, we will proportionate some ideas about how clinical practice could be affected by manipulation of the peripheral nerve biology.

    Tatagiba, M; Penkert, G; Samii, M

    1993-01-01

    The authors present two different types of ganglion affecting the peripheral nerves: extraneural and intraneural ganglion. Compression of peripheral nerves by articular ganglions is well known. The surgical management involves the complete removal of the lesion with preservation of most nerve fascicles. Intraneural ganglion is an uncommon lesion which affects the nerve diffusely. The nerve fascicles are usually intimately involved between the cysts, making complete removal of all cysts impossible. There is no agreement about the best surgical management to be applied in these cases. Two possibilities are available: opening of the epineural sheath lengthwise and pressing out the lesion; or resection of the affected part of the nerve and performing a nerve reconstruction. While in case of extraneural ganglion the postoperative clinical evolution is very favourable, only long follow up studies will reveal in case of intraneural ganglion the best surgical approach.

    Kaiser Wilhelm II of Germany (1859) developed a weak and noticeably short left arm during childhood, commonly attributed to nerve damage caused by the use of excessive force during his difficult breech delivery, Erb's palsy. However, Wilhelm's mother had a severe fall when about four months pregnant and the child was reported to be very thin at birth, suggesting intrauterine growth restriction (IUGR). Wilhelm blamed the British doctor for his deformity, and formed an enmity, which ultimately led to the 1914-1918 world war. We propose an alternative theory, considering the possibility of placental damage and consequential flow redistribution caused by the fall. In severe IUGR, the Doppler pulsatility index (PI) of the brachial arteries differs, that of the right arm being lower than the left. We used a computer model of the fetoplacental unit and reduced its functional placental area until such resistance asymmetry was produced. This would occur in extreme hypoxia when flow in the aortic isthmus is reversed, bringing right ventricular blood of lower oxygen content to the left subclavian artery. The reduced PI in the right arm is a normal vasodilatory hypoxic response, but the apparently normal PI in the left arm results from decreased demand due to metabolic failure. We suggest that the nerve damage affecting the Kaiser's left arm was due to placental insufficiency during pregnancy, and not mechanical brachial plexus injury during delivery. We further suggest that such a mechanism be called Kaiser Wilhelm syndrome to distinguish it from Erb's palsy originating from obstetric trauma. PMID:15893138

    The distance between nerve and stimulation electrode is fundamental for nerve activation in Transcutaneous Electrical Stimulation (TES). However, it is not clear the need to have an approximate representation of the morphology of peripheral nerves in simulation models and its influence in the nerve activation. In this work, depth and curvature of a nerve are investigated around the middle thigh. As preliminary result, the curvature of the nerve helps to reduce the simulation amplitude necessary for nerve activation from far field stimulation.

    Hereditary neuropathy with liability to pressure palsies (HNPP) is a disorder mainly caused by a 1.5-Mb deletion at 17p11.2-12 (and in some rare cases by point mutations) and clinically associated with recurrent painless palsies. Here, we performed electrophysiological (motor, sensory and terminal latency index), MRI and genetic studies in a family referred for ulnar neuropathy with pain. Surprisingly, we found typical neurophysiological features of HNPP (prolongation of distal motor latencies and diffuse SNCV slowing with significant slowing of motor nerve conduction velocities). Besides, the proband presented conduction block in left ulnar, left median and both peroneal nerves. MRI findings were consistent with an underlying neuropathy. Molecular studies identified a novel frameshift mutation in PMP22 confirming the diagnosis of HNPP. Our data suggest that neurophysiological studies are essential to characterize underdiagnosed HNPP patients referred for peripheral neuropathy. Our experience shows that MRI could be a complementary tool for the diagnosis of these patients. PMID:24239057

    It is generally regarded that patients with hereditary neuropathy to pressure palsies, due to a deletion in the PMP22 gene, show recurrent pressure palsy and generalised peripheral neuropathy (pes cavus and hammer toes sometimes develop). Brachial plexopathy is rarely identified as a first presentation of hereditary neuropathy to pressure palsies. We describe a young man who developed a painless flail upper limb with a clinical diagnosis of a brachial plexopathy after his partner slept on his arm – a PMP22 deletion was found. His father, who had a symmetrical polyneuropathy without recurrent mononeuropathies, shared the PMP22 deletion. PMID:25685136

    In the present study we made out an animal model on rabbit whose trigeminus and facialis nerves were simultaneously or only the latter one was severed. The pathological changes in facial muscle atrophy under different nerve injuries were investigated. The degeneration of contractile proteins of upper lip muscle -- myosin and actin was observed. In addition, we also examined the ultrastructural changes in the muscle atrophy in the two above-mentioned nerve injury cases. We observed that the intact trigeminus nerve could delay and lighten the atrophy of facialis-denervated facial muscle and attenuate the degeneration of myosin and actin, as well as decrease the increment of collagen and maintain the ultrastructure of the thick and thin muscle filaments. These results may provide the possibility of improvement of clinical treatment for facial muscle palsy. PMID:11973584

    Bleck, E E

    1980-01-01

    Orthopedic surgery can alleviate the hip flexion, adduction, and medial rotation deformities of the hip and improve the function and appearance of gait. To accomplish this, however, careful examination and prudence in the operative procedure to avoid overdoing and overcorrecting are important. Orthopedic surgery can prevent subluxation and dislocation of the hip before the age of seven years, and consequently repetitive radiographic examinations of the hip in children who have spastic paralysis of the hip musculature should be a routine procedure. Subluxation and dislocation of the hip, when established, can be successfully treated with orthopedic surgical procedures. Physicians must keep in mind that the spastic paralysis of cerebral palsy originates in the brain, and therefore the spasticity cannot be eliminated. The best that can be done is to weaken or remove some muscles as deforming forces and to achieve compromises for continued function. The goal should be optimal independence for the child and adolescent during development, and freedom from pain with deteriorating function due to degenerative arthritis in the adult. PMID:7360505

    2010-01-01

    Osteoporosis is a skeletal disorder characterized by compromised bone strength predisposing a person to an increased risk of fracture.1 Osteoporosis remains a major health problem worldwide, costing an estimated $13.8 billion in health care each year in the United States. Despite advances in treating osteoporosis in the elderly, no cure exists. Osteoporosis has its roots in childhood. Accrual of bone mass occurs throughout childhood and early adulthood, and peak bone mass is a key determinant of the lifetime risk of osteoporosis. Because the foundation for skeletal health is established so early in life, osteoporosis prevention begins by optimizing gains in bone mineral throughout childhood and adolescence.2,3 Osteoporosis evaluation and prevention is relevant to children with cerebral palsy (CP). CP is the most prevalent childhood condition associated with osteoporosis. Bone density is significantly decreased, and children with CP often sustain painful fractures with minimal trauma that impair their function and quality of life. Preventing or improving osteoporosis and maximizing bone accrual during critical stages of growth will minimize the future lifelong risks of fractures in children with CP. This article addresses the anatomy and structure of bone and bone metabolism, the clinical assessment of bone mass, the causes of osteoporosis and its evaluation and treatment in children with CP.

  14. Motor mapping in cerebral palsy.

    PubMed

    Wittenberg, George F

    2009-10-01

    The measurement of motor deficits in individuals with cerebral palsy (CP) has been largely based on clinical criteria. Yet functional imaging and non-invasive stimulation methods provide a means to measure directly abnormalities of the motor system. The size and location of muscles and movement representations can be determined with transcranial magnetic stimulation (TMS) and functional magnetics resonance imaging. Thus the homunculus can be individually mapped in children with CP. Because size of representation within the homunculus relates to quality of motor control, measurement of the distance between body parts provides a metric that may be useful in classifying deficits. Bilateral motor control in one hemisphere, while normal in neonates, persists variably in CP, providing another physiological metric. In this study, we used TMS to measure hand and ankle representations in a convenience sample of children with spastic CP. Overlapping thumb and ankle maps were found in children with both hemiplegia and diplegia, and these maps may be from either side of the body. While more participants are required to make conclusions about disability and compression/bilaterality of the homunculus, it appears as if TMS-derived metrics relate to motor abnormalities. These abnormal motor maps also are a therapeutic target, as stimulation methods are being developed as adjuncts to physical means of rehabilitation. PMID:19740221

    2004-08-01

    Approximately 50 years ago, interest in cerebral palsy increased, and the current definitions and classification were developed. The interplay among the dimensions of significant impairment, nonprogressive lesions, and persistence defines a group of children who were of interest to the researchers who developed the definition. Cerebral palsy as a definition does not attend to the broader issues of neurodevelopmental dysfunction. It isolates a portion of the spectrum of motor dysfunction and creates a category whose bounds are defined by a range of motor capability. The classifications of cerebral palsy that require revision are discussed. Some classifications should be discarded. Others should be brought in line with current knowledge and approaches. Still others should be modified to encompass the broader views of function and therapy that reflect the current expectations for persons with disabilities. PMID:15292880

    1988-04-22

    As part of a study on the organization of the brainstem in a primitive group of vertebrates, the efferent cells and primary afferent fibers of the urodele amphibian Pleurodeles waltlii were examined by means of retrograde and anterograde axonal transport and anterograde degeneration. The trigeminal motor nucleus is located in the periventricular gray just medial to the sulcus limitans. Its rostral part is a band of pear-shaped cells lying parallel to the wall of the ventricle, whereas its caudal part is a round mass consisting of polygonal cells. In addition, a small group of scattered neurons is situated ventral to the rostral part of the nucleus. The primary afferent fibers enter the brainstem in the dorsal two-thirds of the trigeminal root. They diverge into a short ascending and a long descending tract. The former distributes its axons to the principal sensory trigeminal nucleus, which is an ill-defined cell group located at the ventrolateral edge of the periventricular gray. In the descending tract, the fibers of the ophthalmic nerve are predominantly located ventromedially, and those of the maxillomandibular nerve dorsolaterally. A fascicle of the ophthalmic nerve leaves the descending tract and, apparently, makes contact with the accessory abducens nucleus. The descending tract extends caudally into the three upper cervical segments of the spinal cord. The mesencephalic trigeminal nucleus consists of conspicuous large cells, which are scattered through the tectum of the mesencephalon. The cells with peripheral branches in the ophthalmic nerve are mainly located in the caudal half of the tectum, and those with peripheral branches in the maxillomandibular nerve in the rostral half. Collaterals of the central branches of the mesencephalic trigeminal system were traced to an area of the periventricular gray situated between the motor nucleus and the principal sensory nucleus of the trigeminus.

    The typical clinical presentation of hereditary neuropathy with liability to pressure palsies is an adult-onset recurrent, painless monoparesis. Electrophysiological abnormalities--decreased nerve conduction velocities and delayed distal latencies--can be detected even in asymptomatic patients. We describe a toddler, who presented with asymmetric toe walking, painful cramps and stiffness in the legs. He had calf hypertrophy, brisk tendon reflexes and bilateral Babinski signs and the electrophysiological examination was normal. The unlikely diagnosis of hereditary neuropathy with liability to pressure palsies was reached 5 years later, when the boy started to complain of episodic numbness and weakness in the upper extremities. His father, paternal aunt and grandmother had similar symptoms, but they had never been investigated. The typical 1.5 Mb deletion on chromosome 17p11.2-12 was found in our patient and his affected relatives. PMID:14678806

    Three siblings (one boy and two girls) with Brown-Vialetto-van Laere syndrome are reported. A peculiar feature of onset with hearing loss in a patient with multiple cranial nerve palsies and a positive family history suggests this diagnosis.

Optic nerve involvement and hyperintensity of the brainstem nuclei on magnetic resonance imaging (MRI) are two new features described in this report. PMID:16948939

    Atypical sciatica and discrepancy between clinical presentation and imaging findings is a dilemma for treating surgeon in management of lumbar disc herniation. It also constitutes ground for failed back surgery and potential litigations thereof. Furcal nerve (Furcal = forked) is an independent nerve with its own ventral and dorsal branches (rootlets) and forms a link nerve that connects lumbar and sacral plexus. Its fibers branch out to be part of femoral and obturator nerves in-addition to the lumbosacral trunk. It is most commonly found at L4 level and is the most common cause of atypical presentation of radiculopathy/sciatica. Very little is published about the furcal nerve and many are unaware of its existence. This article summarizes all the existing evidence about furcal nerve in English literature in an attempt to create awareness and offer insight about this unique entity to fellow colleagues/professionals involved in spine care.

    Nerve injury is a common complication following intramuscular injection and the sciatic nerve is the most frequently affected nerve, especially in children, the elderly and underweight patients. The neurological presentation may range from minor transient pain to severe sensory disturbance and motor loss with poor recovery. Management of nerve injection injury includes drug treatment of pain, physiotherapy, use of assistive devices and surgical exploration. Early recognition of nerve injection injury and appropriate management are crucial in order to reduce neurological deficit and to maximize recovery. Sciatic nerve injection injury is a preventable event. Total avoidance of intramuscular injection is recommended if other administration routes can be used. If the injection has to be administered into the gluteal muscle, the ventrogluteal region (gluteal triangle) has a more favourable safety profile than the dorsogluteal region (the upper outer quadrant of the buttock).

    The hip adductor group, innervated predominantly by the obturator nerve, occupies a large volume of the lower limb. However, case reports of patients with obturator nerve palsy or denervation have described no more than minimal gait disturbance. Those facts are surprising, given the architectural characteristics of the hip adductors. Our aim was to investigate which regions of the adductor magnus are innervated by the obturator nerve and by which sciatic nerve and to consider the clinical implications. Twenty-one lower limbs were examined from 21 formalin-fixed cadavers, 18 males and 3 females. The adductor magnus was dissected and was divided into four parts (AM1-AM4) based on the locations of the perforating arteries and the adductor hiatus. AM1 was supplied solely by the obturator nerve. AM2, AM3, and AM4 received innervation from both the posterior branch of the obturator nerve and the tibial nerve portion of the sciatic nerve in 2 (9.5%), 20 (95.2%), and 6 (28.6%) of the cadavers, respectively. The double innervation in more than 90% of the AM3s is especially noteworthy. Generally, AM1-AM3 corresponds to the adductor part, traditionally characterized as innervated by the obturator nerve, and AM4 corresponds to the hamstrings part, innervated by the sciatic nerve. Here, we showed that the sciatic nerve supplies not only the hamstrings part but also the adductor part. These two nerves spread more widely than has generally been believed, which could have practical implications for the assessment and treatment of motor disability. PMID:23813615

The tympanic segment of the facial nerve can be reached and visualized using an exclusive transcanal endoscopic approach, even in poorly accessible regions such as the second genu and geniculate ganglion, avoiding mastoidectomy, bony demolition, and meningeal or cerebral lobe tractions, with low complication rates using a minimally invasive surgical route.

    Background. Descriptive evaluation of nerve variations plays a pivotal role in the usefulness of clinical or surgical practice, as an anatomical variation often sets a risk of nerve palsy syndrome. Ulnar nerve (UN) is one amongst the major nerves involved in neuropathy. In the present anatomical study, variations related to ulnar nerve have been identified and its potential clinical implications discussed. Materials and Method. We examined 50 upper limb dissected specimens for possible ulnar nerve variations. Careful observation for any aberrant formation and/or communication in relation to UN has been carried out. Results. Four out of 50 limbs (8%) presented with variations related to ulnar nerve. Amongst them, in two cases abnormal communication with neighboring nerve was identified and variation in the formation of UN was noted in remaining two limbs. Conclusion. An unusual relation of UN with its neighboring nerves, thus muscles, and its aberrant formation might jeopardize the normal sensori-motor behavior. Knowledge about anatomical variations of the UN is therefore important for the clinicians in understanding the severity of ulnar nerve neuropathy related complications. PMID:26246909

    The prevalence of cerebral palsy in the 1958 British Perinatal Mortality Survey and the 1970 British Births Survey remained constant at 2.5/1000 births (40 and 41 cases, respectively). The prevalence at 10 years was higher in the 1970 cohort in which all children with cerebral palsy survived, whereas 22% of the cases in the 1958 cohort died during the first 10 years of life. A case-control study matched three controls for social class, maternal age, parity and marital state, and a further three controls for the infant's sex, gestation, and birth weight. Comparison of cases and controls showed no consistent differences in social and environmental factors, history of pregnancy, labour, or delivery. Important differences were found in the incidence of respiratory and neurological symptoms in the neonatal period. These prospective data derived form two whole populations of births support the hypothesis that most cases of cerebral palsy are not associated with adverse obstetric factors, and confirm that neonatal neurological symptoms are associated with subsequent cerebral palsy.

    A variety of benign and malignant neoplasms occur in the superior cervical neck, parapharyngeal space or the infratemporal fossa. The surgical resection of these lesions may result in postoperative iatrogenic injury to the vagus nerve with associated dysfunctional swallowing and airway protection. Anatomic and functional preservation of this critical cranial nerve will contribute to a favorable surgical outcome. Fourteen patients with tumors of the cervical neck or adjacent skull base underwent intraoperative vagal nerve monitoring in an attempt to preserve neural integrity following tumor removal. Of the 11 patients with anatomically preserved vagal nerves in this group, seven patients had normal vocal cord mobility following surgery and all 11 patients demonstrated normal vocal cord movement by six months. In an earlier series of 23 patients with tumors in the same region who underwent tumor resection without vagal nerve monitoring, 18 patients had anatomically preserved vagal nerves. Within this group, five patients had normal vocal cord movement at one month and 13 patients demonstrated normal vocal cord movement at six months. This paper will outline a technique for intraoperative vagal nerve monitoring utilizing transcricothyroid membrane placement of bipolar hook-wire electrodes in the vocalis muscle. Our results with the surgical treatment of cervical neck and lateral skull base tumors for patients with unmonitored and monitored vagal nerves will be outlined. PMID:8828272

  14. Inferior alveolar nerve repositioning.

    Nerve repositioning is a viable alternative for patients with an atrophic edentulous posterior mandible. Patients, however, should be informed of the potential risks of neurosensory disturbance. Documentation of the patient's baseline neurosensory function should be performed with a two-point discrimination test or directional brush stroke test preoperatively and postoperatively. Recovery of nerve function should be expected in 3 to 6 months. The potential for mandibular fracture when combining nerve repositioning with implant placement also should be discussed with the patient. This can be avoided by minimizing the amount of buccal cortical plate removal during localization of the nerve and maintaining the integrity of the inferior cortex of the mandible. Additionally, avoid overseating the implant, thus avoiding stress along the inferior border of the mandible. The procedure does allow for the placement of longer implants, which should improve implant longevity. Patients undergoing this procedure have expressed overall satisfaction with the results. Nerve repositioning also can be used to preserve the inferior alveolar nerve during resection of benign tumors or cysts of the mandible. This procedure allows the surgeon to maintain nerve function in situations in which the nerve would otherwise have to be resected. PMID:11665379

    During surgery, peripheral nerves are often seen to follow unpredictable paths because of previous surgeries and/or compression caused by a tumor. Iatrogenic nerve injury is a serious complication that must be avoided, and preoperative evaluation of nerve paths is important for preventing it. In this study, transcutaneous electrical nerve stimulation (TENS) was used for an in-depth analysis of peripheral nerve paths. This study included 27 patients who underwent the TENS procedure to evaluate the peripheral nerve path (17 males and 10 females; mean age: 59.9 years, range: 18-83 years) of each patient preoperatively. An electrode pen coupled to an electrical nerve stimulator was used for superficial nerve mapping. The TENS procedure was performed on patients' major peripheral nerves that passed close to the surgical field of tumor resection or trauma surgery, and intraoperative damage to those nerves was apprehensive. The paths of the target nerve were detected in most patients preoperatively. The nerve paths of 26 patients were precisely under the markings drawn preoperatively. The nerve path of one patient substantially differed from the preoperative markings with numbness at the surgical region. During surgery, the nerve paths could be accurately mapped preoperatively using the TENS procedure as confirmed by direct visualization of the nerve. This stimulation device is easy to use and offers highly accurate mapping of nerves for surgical planning without major complications. The authors conclude that TENS is a useful tool for noninvasive nerve localization and makes tumor resection a safe and smooth procedure. PMID:26420473

    The involvement of lower cranial nerve palsies is less frequent in Ramsay Hunt syndrome caused by varicella zoster virus (VZV). The authors report 1 of extremely rare patients of radiologically proven polyneuropathy of VZV infection with magnetic resonance imaging findings of VII, IX, and X cranial nerve involvement is a 62-year-old female patient, who initially presented with Ramsay Hunt syndrome. Varicella zoster virus infection should be considered even in patients who show unilateral palsy of the lower cranial nerves associated with laryngeal paralysis. Thin-section T2W and T1W images with a contrast agent should be added to the imaging protocol to show the subtle involvement. PMID:27092925

    We report a case of a 43-year-old male who sustained an axillary nerve injury secondary to a glenohumeral joint dislocation at a young age, and who has served over 20 years in the military with near normal shoulder function. In addition, we review the literature for the natural history of axillary nerve injury. A 43-year-old male sustained a left anterior glenohumeral dislocation in a motor vehicle accident as an 18-year-old. Following prompt manual reduction and subsequent physical therapy, the patient developed a permanent axillary nerve palsy. Despite the development of complete atrophy of his deltoid musculature and persistent sensory loss in the axillary nerve distribution, he experienced restoration of function with minimal to no deficit. Ultimately, he enlisted in the military 4 years after the injury and has served 22 years, which includes combat deployments with normal shoulder function and absence of pain. Axillary nerve injury is a relatively common injury after anterior glenohumeral joint dislocation. There is little known about the long-term outcome of patient's with permanent axillary nerve injury. This case suggests that it is possible for a young athletic individual to function at a high level of activity after permanent loss of axillary nerve function. PMID:26926757

  20. Inherited focal, episodic neuropathies: hereditary neuropathy with liability to pressure palsies and hereditary neuralgic amyotrophy.

    PubMed

    2006-01-01

    Hereditary neuropathy with liability to pressure palsies (HNPP; also called tomaculous neuropathy) is an autosomal-dominant disorder that produces a painless episodic, recurrent, focal demyelinating neuropathy. HNPP generally develops during adolescence, and may cause attacks of numbness, muscular weakness, and atrophy. Peroneal palsies, carpal tunnel syndrome, and other entrapment neuropathies may be frequent manifestations of HNPP. Motor and sensory nerve conduction velocities may be reduced in clinically affected patients, as well as in asymptomatic gene carriers. The histopathological changes observed in peripheral nerves of HNPP patients include segmental demyelination and tomaculous or "sausage-like" formations. Mild overlap of clinical features with Charcot-Marie-Tooth (CMT) disease type 1 (CMT1) may lead patients with HNPP to be misdiagnosed as having CMT1. HNPP and CMT1 are both demyelinating neuropathies, however, their clinical, pathological, and electrophysiological features are quite distinct. HNPP is most frequently associated with a 1.4-Mb pair deletion on chromosome 17p12. A duplication of the identical region leads to CMT1A. Both HNPP and CMT1A result from a dosage effect of the PMP22 gene, which is contained within the deleted/duplicated region. This is reflected in reduced mRNA and protein levels in sural nerve biopsy samples from HNPP patients. Treatment for HNPP consists of preventative and symptom-easing measures. Hereditary neuralgic amyotrophy (HNA; also called familial brachial plexus neuropathy) is an autosomal-dominant disorder causing episodes of paralysis and muscle weakness initiated by severe pain. Individuals with HNA may suffer repeated episodes of intense pain, paralysis, and sensory disturbances in an affected limb. The onset of HNA is at birth or later in childhood with prognosis for recovery usually favorable; however, persons with HNA may have permanent residual neurological dysfunction following attack(s). Episodes are often

  1. Identification alone versus intraoperative neuromonitoring of the recurrent laryngeal nerve during thyroid surgery: experience of 2034 consecutive patients

    PubMed Central

    2014-01-01

    Background The aim of this study was to evaluate the ability of intraoperative neuromonitoring in reducing the postoperative recurrent laryngeal nerve palsy rate by a comparison between patients submitted to thyroidectomy with intraoperative neuromonitoring and with routine identification alone. Methods Between June 2007 and December 2012, 2034 consecutive patients underwent thyroidectomy by a single surgical team. We compared patients who have had neuromonitoring and patients who have undergone surgery with nerve visualization alone. Patients in which neuromonitoring was not utilized (Group A) were 993, patients in which was utilized (group B) were 1041. Results In group A 28 recurrent laryngeal nerve injuries were observed (2.82%), 21 (2.11%) transient and 7 (0.7%) permanent. In group B 23 recurrent laryngeal nerve injuries were observed (2.21%), in 17 cases (1.63%) transient and in 6 (0.58%) permanent. Differences were not statistically significative. Conclusions Visual nerve identification remains the gold standard of recurrent laryngeal nerve management in thyroid surgery. Neuromonitoring helps to identify the nerve, in particular in difficult cases, but it did not decrease nerve injuries compared with visualization alone. Future studies are warranted to evaluate the benefit of intraoperative neuromonitoring in thyroidectomy, especially in conditions in which the recurrent nerve is at high risk of injury.

    Mapping nerve deficits during a physical exam after trauma to the upper extremity can help determine not only if the brachial plexus was injured but also which nerve roots were involved. A 28-year-old male presented with simultaneous signs and symptoms of Erb’s (C5) and Klumpke’s (C8, T1) palsy, with sparing of the C6 and C7 roots. The patient presented several months ago to his local emergency room with shortness of breath, which was determined to be caused by left diaphragmatic paralysis through clinical and radiographical evidence. However, the etiology of the current nerve dysfunction in the upper extremity remained unknown. With persistent questioning and establishing the patient’s trust in the caregivers, it was revealed that the patient had attempted suicidal hanging. We describe the clinical features and the likely mechanism of injury leading to this previously unreported combination of brachial plexus injuries. The unique injuries to this patient’s brachial plexus can be explained by the sequence of events during the attempted suicidal hanging. The upper brachial plexus was injured during the initial moments where the neck was excessively stretched and the lower brachial plexus was injured due to the patient reaching up and holding himself by his arm for an extended period of time.

    Two patients with diabetes mellitus, one of them with an isolated third cranial nerve palsy and the other with an isolated sixth cranial nerve palsy, are presented. MRI investigations including diffusion-weighted MRI revealed a small ischemic brain stem lesion in the former and a small hemorrhagic brain stem lesion in the latter. In the former case wallerian degeneration of the nerve fascicle within the mesencephalon was also detected. These cases indicate that vascular accidents of the brain stem may masquerade as fascicular or infranuclear disturbance of the oculomotor or abducens nerve; therefore, it is important to include brain stem lesions into the differential diagnosis of isolated ophthalmoplegia. Thorough investigation by MRI including diffusion-weighted MRI is helpful for correct diagnosis. PMID:7656493

    Peripheral nerve injuries are challenging problems. Nerve transfers are one of many options available to surgeons caring for these patients, although they do not replace tendon transfers, nerve graft, or primary repair in all patients. Distal nerve transfers for the treatment of high ulnar nerve injuries allow for a shorter reinnervation period and improved ulnar intrinsic recovery, which are critical to function of the hand.

  5. Minor congenital anomalies and ataxic cerebral palsy.

    PubMed Central

    Miller, G

    1989-01-01

    The incidence of minor congenital anomalies was examined in 36 patients with ataxic cerebral palsy, in unaffected family members, and in 100 unrelated control subjects. None of the control subjects or family members had more than four anomalies, and 25 of 36 (69%) of the patients had more than four. The distribution of anomalies differed considerably, with 60% of the index cases having seven or more, and 94% of the controls having three or less. The number occurring in the patients was significantly more than in their relatives. Of the 25 patients with more than four anomalies, 16 (64%) had undergone potentially adverse perinatal or early postnatal events. Thus minor congenital anomalies were considerably more frequent in those with ataxic cerebral palsy than in related or unrelated control subjects. These anomalies may be markers of early prenatal factors that contributed to the adverse outcome either directly or by predisposing to perinatal difficulties. PMID:2751330

    Cerebral palsy is the musculoskeletal manifestation of a nonprogressive central nervous system lesion that usually occurs due to a perinatal insult to the brain. Though the cerebral insult is static the musculoskeletal pathology is progressive. Some patients with cerebral palsy whose hands are affected can be made better by surgery. The surgical procedures as such are not very technically demanding but the assessment, decision-making, and selecting the procedures for the given patient make this field challenging. When done well, the results are rewarding not only in terms of improvement in hand function but also in appearance and personal hygiene, which leads to better self-image and permits better acceptance in the society. This article focuses on the clinical examination, patient selection, and decision-making while managing these patients. PMID:22022045

    A 36-year-old woman was admitted to our hospital for further examination of an acute febrile illness with liver dysfunction. A peripheral blood smear displayed atypical lymphocytes. Cytomegalovirus (CMV) mononucleosis was diagnosed based on the detection of CMV-specific IgM and conventional CMV pp65 antigen. The physical examination on admission revealed signs of lower motor neuron right facial palsy. There were no significant cerebrospinal fluid findings, nor were there other neurological abnormalities. After receiving a short-course of oral corticosteroids, the patient gradually recovered from the facial paralysis. A one-month follow-up examination indicated that she had fully recovered neurologically, showing disappearance of CMV-DNA and a significant increase in the anti-CMV IgG titer. To our knowledge, there has been only one previous report describing CMV as the cause of an isolated facial palsy combined with CMV mononucleosis. PMID:24681941

    1986-01-01

    The trigeminal function was investigated in 30 consecutive patients with acute unilateral peripheral facial palsy. The patients were tested with electrophysiological methods within 5 weeks after onset of the disease. Trigeminus-evoked potential test (TEP) disclosed trigeminal dysfunction in 47%, while the blink reflex test (BR) showed trigeminal pathology in 60% of the patients. A topographical analysis of the trigeminal system showed that 24% of the patients had BR patterns that were consistent with brainstem involvement. In 2 cases (7%), TEP was pathological though the BR test proved normal. These findings suggest a more central trigeminal affection and may demonstrate multifocal lesions. This was further underlined by the investigation of the auditory brainstem response (ABR) which indicated brainstem involvement in 28%. It is concluded that acute facial palsy is frequently a symptom of a central nervous affection. PMID:3705951

    We report a case of an intraneural ganglion cyst of the hypoglossal canal. The patient presented with unilateral hypoglossal nerve palsy, and magnetic resonance imaging showed a small lesion in the hypoglossal canal with no contrast enhancement and high signal on T2-weighted imaging. The lesion was assumed to be a cystic schwannoma of the hypoglossal nerve. Stereotactic irradiation was considered, but in accordance with the patient's wishes, surgical exploration was performed. This revealed that, rather than a schwannoma, the patient had an intraneural ganglion cyst, retrospectively contraindicating irradiation as an option. This case illustrates a very rare location of an intraneural ganglion cyst in the hypoglossal nerve. To our knowledge there are no previous reports of an intraneural ganglion cyst confined to the hypoglossal canal. PMID:26251801

    Nerve repair after injury can be effectively accomplished by direct suture approximation of the proximal and distal segments. This is more successful if coadaptation can be achieved without tension. Currently, the gold standard repair of larger deficits is the transplantation of an autologous sensory sural nerve graft. However, a significant disadvantage of this technique is the inevitable donor morbidity (sensory loss, neuroma and scar formation) after harvesting of the sural nerve. Moreover, limitation of autologous donor nerve length and fixed diameter of the available sural nerve are major drawbacks of current autograft treatment. Another approach that was introduced for nerve repair is the implantation of alloplastic nerve tubes made of, for example, poly-L-lactide. In these, nerve stumps of the transected nerves are surgically bridged using the biosynthetic conduit. A number of experimental studies, primarily in rodents, indicate axonal regeneration and remyelination after implantation of various conduits. However, only limited clinical studies with conduit implantation have been performed in acute peripheral nerve injuries particularly on digital nerves. Clinical transfer of animal studies, which can be carefully calibrated for site and extent of injury, to humans is difficult to interpret due to the intrinsic variability in human nerve injuries. This prevents effective quantification of improvement and induces bias in the study. Therefore, standardization of lesion/repair in human studies is warranted. Here we propose to use sural nerve defects, induced due to nerve graft harvesting or from diagnostic nerve biopsies as a model site to enable standardization of nerve conduit implantation. This would help better with the characterization of the implants and its effectiveness in axonal regeneration and remyelination. Nerve regeneration can be assessed, for example, by recovery of sensation, measured non-invasively by threshold to von Frey filaments and cold

    Surgery for pleomorphic adenoma recurrence presents a significant risk of facial nerve damage that can result in facial weakness effecting patients' ability to communicate, mental health and self-image. We report two case studies that had marked facial weakness after resection of recurrent pleomorphic adenoma and their progress with electrical stimulation. Subjects received electrical stimulation twice daily for 24 weeks during which photographs of expressions, facial measurements and Sunnybrook scores were recorded. Both subjects recovered good facial function demonstrating Sunnybrook scores of 54 and 64 that improved to 88 and 96, respectively. Neither subjects demonstrated adverse effects of treatment. We conclude that electrical stimulation is a safe treatment and may improve facial palsy in patients after resection of recurrent pleomorphic adenoma. Larger studies would be difficult to pursue due to the low incidence of cases. PMID:27106613

    Management of hereditary neuropathy with liability to pressure palsy (HNPP) is primarily conservative, aimed at preventing nerve injury by avoiding trauma or other potential aggravating factors. No pharmacological treatment is known to be beneficial. We describe two adolescents, one with HNPP (male; aged 15y) and another with a clinical picture suggestive of HNPP (genetically unconfirmed; female; aged 14y), who showed considerable improvement of their symptoms after receiving corticosteroid therapy. Both individuals were symptomatic for at least 5 months before the treatment. Following corticosteroids, both individuals demonstrated rapid improvement leading to near-complete recovery of muscle power. Clinical improvement after corticosteroid therapy has been reported in some individuals with other hereditary neuropathies. Our cases demonstrate that corticosteroid therapy may also be beneficial in individuals with HNPP who have a protracted or incomplete course of recovery. PMID:22098098

    Acute distal biceps tendon rupture constitute a rare lesion of biceps injuries, typically, easy to diagnosis after lifting a heavy object. Treatment is controversial, nonoperative for sedentary and elderly patients; surgical for young and active individuals. Many operative techniques are described, they all aim to restore an excellent strength of flexion and supination. We opted for one-incision method and fixation using trans-osseous anchoring for our patient, because we are convinced that is a simpler and safer technique. Postoperative rehabilitation, after a period of elbow immobilization, must be operated for returning to full activity. Biceps tendon repair has permitted to our patient who suffer from right upper limb handicap due to radial nerve palsy, recuperating the lost strength and force in his dominant limb and maintaining some quality of life.

    Hereditary neuropathy with liability to pressure palsies is an inherited disease associated with the loss of a copy of the PMP22 gene. The condition leads to mononeuropathy due to compression and easy strangulation during daily life activities, resulting in sudden muscle weakness and sensory disturbance, and displaying symptoms similar to cerebrovascular diseases. We report the case of an 80-year-old man with left paralysis due to chronic cerebral infarction. His medical history indicated remarkable recovery from about 4 months after the onset of left hemiplegia with predominant involvement of the fingers. Despite subsequent recurrent monoplegia of the upper or lower limbs, brain magnetic resonance imaging consistently revealed only previous cerebral infarction in the right corona radiata without new lesions. Medical examination showed reduced deep tendon reflexes in his extremities on both the healthy and hemiplegic sides. Nerve conduction studies showed delayed conduction at the bilateral carpal and cubital tunnels and near the right caput fibulae. Genetic analysis revealed loss of a copy of the PMP22 gene. Thus, he was diagnosed with a cerebral infarction complicated by hereditary neuropathy with liability to pressure palsies. Stroke patients develop sudden muscle weakness and sensory disturbance. However, if such patients have no hyperactive deep tendon reflexes and show atypical recovery of paralysis that does not correspond to findings of imaging modalities, nerve conduction studies and genetic analysis may be necessary, considering the complication of hereditary neuropathy with liability to pressure palsies.

    Introduction Sonography in classical nerve entrapment syndromes is an established and validated method. In contrast, few publications highlight lesions of the radial nerve, particularly of the posterior interosseus nerve (PIN). Method Five patients with a radial nerve lesion were investigated by electromyography, nerve conduction velocity and ultrasound. Further normative values of 26 healthy subjects were evaluated. Results Four patients presented a clinical and electrophysiological proximal axonal radial nerve lesion and one patient showed a typical posterior interosseous nerve syndrome (PINS). The patient with PINS presented an enlargement of the PIN anterior to the supinator muscle. However four patients with proximal lesions showed an unexpected significant enlargement of the PIN within the supinator muscle. Conclusion High-resolution sonography is a feasible method to demonstrate the radial nerve including its distal branches. At least in axonal radial nerve lesions, sonography might reveal abnormalities far distant from a primary proximal lesion site clearly distinct from the appearance in classical PINS. PMID:25992766

    The studies testifying to the presence of the interrelation between the physiological functions of the organism and physical and chemical processes in nerves are discussed. Changes in some physical and chemical parameters observed both upon elicited rhythmic exaltation of nerves and during the spontaneous rhythmic activity of neurons are analyzed. Upon rhythmic exaltation, a complex of physical and chemical processes is triggered, and reversible structural and metabolic rearrangements at the subcellular and molecular levels occur that do not take place during the generation of a single action potential. Thus, only in conditions of rhythmic exaltation of a nerve, it is possible to reveal those processes that provide exaltation of nerves in the organism. The future possibilities of the investigations combining the biophysical and physiological approaches are substantiated. Characteristic changes in physicochemical parameters are observed in nerves during the generation of a series of action potentials of different frequency and duration ("frequency dependence") under normal physiological conditions, as well as in extreme situations and in nerve pathology. The structural and metabolic rearrangements are directly related to the mode of rhythmic exaltation and proceed both in the course of rhythmic exaltation and after its termination. Participation and the basic components of the nervous fulcrum (an axon, Shwan cell, myelin, subcellular organelles) in the realization of rhythmic exaltation is shown. In the coordination of all processes involved in rhythmic exaltation, the main role is played by the systems of redistribution and transport of intercellular and endocellular calcium. The idea is put forward that myelin of nerve fibers is not only an isolator, but also an "intercellular depot" of calcium and participates in the redistribution of different ions. Thus, the rhythmic excitation is of great importance in the realization of some physiological functions, the

    A register has been compiled of the 421 children with congenital cerebral palsy born between 1960 and 1975 from a defined geographical area of North East England (population 770 000). There was a fall in the rate of cerebral palsy among very low birthweight babies between 1964 and 1975 and also in the small group with dyskinetic cerebral palsy. The rate rose, however, among babies weighing more than 2.5 kg at birth in the second half of the study, in parallel with changes in perinatal mortality. The net effect is that the overall congenital cerebral palsy rate (mean 1.64 per 1000 livebirths) showed a gradual rise between 1968 and 1975. This conclusion is reinforced by evidence of a rise in incidence among the subgroup of patients with severe cerebral palsy (as defined by an interval measurement of handicap) during the same period.

    Children with neurodevelopmental disabilities, such as cerebral palsy, are considered to be a population at risk for the occurrence of sleep problems. Moreover, recent studies on children with cerebral palsy seem to indicate that this population is at higher risk for sleep disorders. The importance of the recognition and treatment of sleep problems in children with cerebral palsy cannot be overemphasized. It is well known that the consequences of sleep disorders in children are broad and affect both the child and family. This review article explores the types and possible risk factors associated with the development of sleep problems in children with cerebral palsy and the impact of this disorder on the child and family. In addition, a brief summary of current diagnostic and treatment modalities is provided. Finally, the characteristics, diagnostic techniques, and management of sleep-related breathing disorders in children with cerebral palsy are discussed. PMID:21670393

    Introduction Preservation of the temporal branches of the facial nerve during anterolateral craniotomies is important. Damaging it can inflict undesirable cosmetic defects to the patient. The supraorbital trans-eyebrow approach (SOTE) is a versatile keyhole craniotomy but still has a high rate of frontalis muscle (FM) palsy. Objective Anatomical study to implement the interfascial dissection during the SOTE to preserve the nerves to the FM. Methods Slight modification of the standard technique of the SOTE was performed in 6 cadaveric specimens (12 sides). Results Distal rami to the FM were exposed. The standard "u-shape" incision of the FM can cross over the nerves. Alternatively, an "l-shape" incision was performed until the superior temporal line (STL). An interfascial dissection was performed near to the STL and the interfascial fat pad was used as a protective layer for the nerves. Conclusion Various pathologies can be addressed with the SOTE. In the majority of the cases the cosmetic results are good, but FM palsy remains a drawback of this approach. The interfascial dissection may be used in an attempt to prevent frontalis rami palsy.

    2015-01-01

    Recurrent laryngeal nerve palsy is a common post-operative complication of many head and neck surgeries. Theoretically, the best treatment to restore partial function to a damaged recurrent laryngeal nerve would be reinnervation of the posterior cricoarytenoid muscle via anastomosis of the recurrent laryngeal and phrenic nerves. The pig is an excellent model of human laryngeal anatomy and physiology but a more thorough knowledge of porcine laryngeal anatomy is necessary before the pig can be used to improve existing surgical strategies, and develop new ones. This study first identifies the three most common recurrent laryngeal nerve branching patterns in the pig. Secondly, this study presents three-dimensional renderings of the porcine larynx onto which the recurrent laryngeal nerve patterns are accurately mapped. Lastly, heat maps are presented to display the spatial variability of recurrent laryngeal nerve trunks and primary branches on each side of 15 subjects (28 specimens). We intend for this study to be useful to groups using a porcine model to study posterior cricoarytenoid muscle reinnervation techniques. PMID:27086418

We also elucidate where, and how, the homeostasis of the normal human peripheral nerve is controlled in situ and how claudin-containing tight junctions contribute to the barriers of peripheral nerve. Also, the human timeline of the development of the barriers of the peripheral nerve is depicted. Finally, potential future therapeutic modalities interfering with the barriers of the peripheral nerve are discussed. PMID:24665400

    Background and Importance Intraosseous schwannoma is a relatively rare clinical entity that typically arises in vertebral and mandibular bone. Intraosseous schwannoma located entirely within the petrous bone is exceedingly rare, and only two cases have been reported to date. Clinical Presentation A 47-year-old Asian man was referred to our hospital with a chief complaint of double vision. Neurologic examination revealed left abducens nerve palsy. Radiologic imaging showed a 35-mm osteolytic expansive lesion located in the left petrous apex. We made a preoperative diagnosis of chondrosarcoma and performed surgical resection. Surgery was performed via a left subtemporal epidural approach with anterior petrosectomy. The histopathologic diagnosis of the tumor was schwannoma. Schwannoma arising from cranial nerves was excluded from intraoperative findings in conjunction with the results for cranial nerves, and intraosseous schwannoma was diagnosed. Postoperative course was uneventful, and abducens nerve palsy resolved immediately after surgery. Conclusion The differential diagnosis of intraosseous schwannoma should be considered for an osteolytic mass lesion within the petrous apex. Subcapsular tumor removal was considered ideal in terms of preservation of the cranial nerves and vessels around the tumor. PMID:26251791

    Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder characterized by postural instability and falls, vertical supranuclear gaze palsy, parkinsonism with poor levodopa response, pseudobulbar palsy, and frontal release signs. The natural history of the disease has been previously described. However, the time frame of appearance of clinical milestones and how these symptoms may relate to survival in PSP are unknown. The primary objective was to determine the prevalence of symptoms at different stages of PSP and to estimate the time of appearance of clinical symptoms characteristic of the disease. Second, we determined the association between clinical symptoms and survival. We prospectively studied 35 PSP patients during assessments scheduled every 6 months for up to 2 years. We estimated symptoms prevalence and the association between symptoms and survival. The median age of onset was 65.9 years (IQR 60.6-70.0), and the median time from onset to first assessment was 3.0 years (IQR 2.4-3.9). The most commonly reported symptoms at baseline were: motor (100%) followed by cognitive/behavioral (89%), systemic and bulbar (80%), and sleep disturbances (60%). Slowness of movement, falls, neck stiffness and difficulty looking up/down had high prevalence from baseline, while balance and gait impairment were less common at baseline but increased in prevalence over time. The presence of sleep disturbances, and possibly hallucinations, was associated with increased death risk. Improved recognition of the clinical spectrum and milestones of PSP advances knowledge of the disease, helps earlier diagnosis, and allows prognostic predictions. PMID:26705121

    Diaphragmatic palsy in hemiparetic stroke is not well recognized. Further, its implications on stroke outcome have not been studied. Here, we report a patient with left-sided diaphragmatic palsy due to an acute right middle cerebral artery territory infarction. The diagnosis was suspected on finding an elevated dome of the diaphragm on the left side in a routine chest radiograph and was confirmed by finding decreased movements of the left hemidiaphragm on fluoroscopic examination. We hypothesize that this condition is probably under-recognized in clinical practice and its clinical importance not well known. The pathophysiological basis of diaphragmatic palsy in acute stroke and its possible clinical implications are discussed. PMID:19881177

    The incidence of facial palsy is about 50/100000/year, i.e. 210 cases/year in Geneva. Clinicians can be puzzled by it, because it encompasses aetiologies with very diverse prognoses. Most patients suffer from Bell palsy that evolves favourably. Some, however, suffer from diseases such as meningitis, HIV infection, Lyme's disease, CVA, that require fast identification because of their severity and of the need for specific treatments. This article proposes an algorithm for pragmatic and evidence-based management of facial palsy. PMID:19267054

    The pharyngeal-cervical-brachial (PCB) variant of Guillain-Barré syndrome is rare in children. It is characterized by oropharyngeal, neck, and upper limb muscle involvement, without ataxia and disturbed consciousness. Although associated with anti-GT1a antibodies, there is no single clinical or serological marker of PCB syndrome. We report on two cases in a 14-year-old and a 15-year-old females. The first symptom was acute dysphonia followed by severe bulbar palsy with deglutition disorders, associated with involvement of other cranial nerves and arm and leg weakness. One of the girls had normal deep tendon reflexes. Both had normal cerebral imaging and normal cerebrospinal fluid. No sign of neuropathy was found on nerve conduction studies. The diagnosis of PCB syndrome was established based on the presence of antiganglioside antibodies. Both adolescents had IgG anti-GT1a antibodies. Anti-GQ1b and anti-GT1b antibodies were associated in the first case, anti-GM1 and anti-GD1a in the second case. Clinical improvement was fast after treatment with intravenous immunoglobulin therapy. Recovery was complete. Only a few cases of children and adolescents with PCB syndrome have been reported. The main differential diagnoses were excluded with brain MRI. The neurophysiological findings in PCB syndrome are axonal neuropathy rather than demyelinating neuropathy, which might be normal in the early stages of the disease. Positivity of anti-GT1a IgG antibodies is very helpful for the diagnosis of PCB syndrome. In atypical cases of bulbar palsy with other cranial nerve involvement and normal brain MRI, diagnosis of PCB syndrome should be considered. Recognizing the atypical cases of Guillain-Barré syndrome enables anticipatory monitoring for disease complications and identifies therapeutic options. The short- and long-term outcome of the PCB syndrome after intravenous immunoglobulin treatment seems favorable. PMID:26697812

    Cerebral palsy (CP) is a catastrophic acquired disease, occurring during development of the fetal or infant brain. It mainly affects the motor control centres of the developing brain, but can also affect cognitive functions, and is usually accompanied by a cohort of symptoms including lack of communication, epilepsy, and alterations in behavior. Most children with cerebral palsy exhibit a short stature, progressively declining from birth to puberty. We tested here whether this lack of normal growth might be due to an impaired or deficient growth hormone (GH) secretion. Our study sample comprised 46 CP children, of which 28 were male and 18 were female, aged between 3 and 11 years. Data obtained show that 70% of these children lack normal GH secretion. We conclude that GH replacement therapy should be implemented early for CP children, not only to allow them to achieve a normal height, but also because of the known neurotrophic effects of the hormone, perhaps allowing for the correction of some of the common disabilities experienced by CP children.

    A register of infants with cerebral palsy born to mothers resident in the Mersey region from 1967-84 has been maintained using various sources of information. A total of 1056 patients are registered of whom 331 (31%) have hemiplegia or mixed hemiplegia, 236 (22%) have diplegias or mixed diplegia, and 369 (35%) have quadriplegia or mixed quadriplegia. The remainder have dyskinetic or dystonic forms except for seven, who are unclassified. There has been no significant change in the prevalence of cerebral palsy among infants of normal birth weight (greater than 2500 g). Among low birthweight infants (less than or equal to 2500 g) there has been a significant increase in prevalence of all the main clinical types. This increase started later among the very low birthweight infants (less than or equal to 1500 g) than among those weighing 1501-2500 g. These changes in prevalence could be the result of either improved survival of prenatally impaired infants because of improvements in medical care, or a reflection of failure to maintain optimal conditions at or around the time of birth.

    2016-02-01

    Brachial plexus birth palsy (BPBP) is defined as an injury to any nerve root of the brachial plexus during difficult delivery. BPBP is relatively rare; its incidence has remained constant over the last few decades, mostly due to unpredictable risk factors, such as shoulder dystocia. Both diagnosis and assessment of spontaneous recovery is based on clinical examination. Electromyography is difficult to interpret in the newborn and is therefore not meaningful. MRI of the cervical spine requires sedation or general anesthesia. Searching for a pre-ganglion tear prior to surgery is indicted. Prognosis depends on the level of the injury (pre- or post-ganglion), size and severity of the post-ganglion tears, speed of recovery, and quality of initial management. Although spontaneous recovery is frequent, some children suffer various degrees of sequelae, up to complete loss of function of the affected upper limb. Recent publications have improved general knowledge and indications for surgery. However, some aspects, such as indication and timing of nerve repair continue to be debated. PMID:26774906

    Background Climatic or meteorological condition changes have been implicated in the pathogenesis of Bell's palsy (BP). We evaluate the influence of meteorological parameters, such as temperature, humidity, and atmospheric pressure, and their variation and covariation on the incidence of BP and present a review of the literature on the effect of meteorological conditions on facial nerve function. Methods A total of 171 cases of BP admitted to our Department over a five-year period were studied. The meteorological database included daily values of 13 distinct parameters recorded at the meteorological station of the University of Ioannina during this period. A relationship between each meteorological variable and the incidence of BP was investigated by applying (Χ2) test on data from 13 contingency tables. In addition, the influence of different weather types on the incidence of BP was also investigated. For this purpose Cluster Analysis was used to create eight clusters (weather types) for the Ioannina prefecture and (Χ2) test was applied on the contingency tables consisting of the days of BP cases for each cluster. Results No significant correlation was found either between BP and each distinct meteorological parameter or between BP and any specific weather. Conclusions Meteorological conditions, such as those dominating in the Northwestern Greece, and/or their changes have little effect on the incidence of BP. Multicenter studies taking into account atmospheric pollution, and climatic differences between countries, are necessary to scrutinize the environmental effects on facial nerve function.

    Laryngeal palsy often occurs as a result of recurrent laryngeal or vagal nerve injury during oncological surgery of the head and neck, affecting quality of life and increasing economic burden. Reinnervation following recurrent laryngeal nerve (RLN) injury is difficult despite development of techniques, such as neural anastomosis, nerve grafting and creation of a laryngeal muscle pedicle. In the present study, due to the limited availability of human nerve tissue for research, a rat model was used to investigate neurotrophin expression and laryngeal muscle pathophysiology in RLN injury. Twenty-five male Sprague-Dawley rats underwent right RLN transection with the excision of a 5-mm segment. Vocal fold movements, vocalization, histology and immunostaining were evaluated at different time-points (3, 6, 10 and 16 weeks). Although vocalization was restored, movement of the vocal fold failed to return to normal levels following RLN injury. The expression of brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor differed in the thyroarytenoid (TA) and posterior cricoarytenoid muscles. The number of axons did not increase to baseline levels over time. Furthermore, normal muscle function was unlikely with spontaneous reinnervation. During regeneration following RLN injury, differences in the expression levels of neurotrophic factors may have resulted in preferential reinnervation of the TA muscles. Data from the present study indicated that neurotrophic factors may be applied for restoring the function of the laryngeal nerve following recurrent injury. PMID:26677138

    Over the last decade, neuromuscular ultrasound has emerged as a useful tool for the diagnosis of peripheral nerve disorders. This article reviews sonographic findings of normal nerves including key quantitative ultrasound measurements that are helpful in the evaluation of focal and possibly generalized peripheral neuropathies. It also discusses several recent papers outlining the evidence base for the use of this technology, as well as new findings in compressive, traumatic, and generalized neuropathies. Ultrasound is well suited for use in electrodiagnostic laboratories where physicians, experienced in both the clinical evaluation of patients and the application of hands-on technology, can integrate findings from the patient’s history, physical examination, electrophysiological studies, and imaging for diagnosis and management.

    Brachial plexus palsy affects children differently than adults. In children with obstetric brachial plexus palsy, motor development must depend on nervous system adaptation. Previous studies report sensory plasticity in these children. This noninvasive study provides support for neural plasticity (the general ability of the brain to reorganize neural pathways based on new experiences) in children with obstetric brachial plexus palsy by considering upper limb preference. As in the general population, we expect that 90% of children would prefer their right upper limb. However, only 17% of children affected by right obstetric brachial plexus palsy prefer the right upper limb for overall movement; children with left obstetric brachial plexus palsy did not significantly differ from the general population in upper limb preference. This study also provides the first evidence of a significant correlation between actual task performance and select obstetric brachial plexus palsy outcome measurement systems, thereby justifying the routine use of these outcome measurement systems as a reflection of the practical utility of the affected limb to the patient.

[Subjects and Methods] Thirty-seven children between the ages of 5 and 14 diagnosed with hemiplegic cerebral palsy (19 right, 18 left) and 23 healthy gender- and age-matched controls were included in the study. Postural stability was evaluated in both of the groups using a Neurocom Balance. Sway velocity was measured both with the eyes open and closed. Sit to stand and turning abilities were also assessed. [Results] The sway velocities with the eyes open and closed were significantly different between the groups. The weight transfer time in the Sit to Stand test was also significantly slower in children with cerebral palsy. Children with cerebral palsy also showed slower turning times and greater sway velocities during the Step and Quick Turn test on a force plate compared with their healthy counterparts. [Conclusion] Both static and dynamic postural stability parameters are affected in hemiplegic cerebral palsy. Further research is needed to define rehabilitation interventions to improve these parameters in patients. PMID:27313338
