Extractions: Introduction: In 1886 Charcot and Marie reported a case of hereditary motor and sensory neuropathy that was identical to a case simultaneously and independently described by Tooth. Inherited in an autosomal dominant pattern, HMSN1 is characterized by slowly progressive weakness and muscle wasting in distal limb muscles, initially in the legs. It progresses slowly upwards to involve the muscles of the upper extremities. During the past century, several reports have described cases of HMSN1 in which oculomotor dysfunction was found in combination with the more typical findings of the disease. On occasion, oculomotor abnormalities, such as ptosis or diplopia, have been reported as cases of HMSN1, when other problems may have been at fault, such as myasthenia gravis, CPEO, or Horner's syndrome. We describe a case in which a patient previously diagnosed as having HMSN1 was found to have a partial IIIrd cranial nerve palsy. Case: A 38 year old man was referred to our out patient department with a two year history of vertical diplopia. As an infant he had been treated for hip joint dysplasia, and he had also had childhood onset of a gait disorder and unsteadiness on his feet. At the age of 19 he acquired the diagnosis of HMSN1. During subsequent years he had only minimal and slow progression of his neurological symptoms. An ophthalmic examination found evidence of a partial, unilateral IIIrd cranial nerve paresis, but the remainder of his ophthalmic examination was unremarkable.

NeuroCAST - Diagnosing Hereditary Peripheral Neuropathy 1 Among idiopathic peripheral neuropathy cases, DNA testing ultimately identifiesabout 42% of the cases as hereditary motorsensory neuropathy (HMSN), also http://www.neurocast.com/site/content/sessions_06_2002.asp
Extractions: Peripheral neuropathy encompasses a host of conditions resulting from damage to the peripheral nerves. Diagnosing peripheral neuropathies can present a challenge to neurologists because other diseases and disorders have similar symptoms - numbness, weakness, incoordination or other sensory or motor disturbance. Following a method described by Cornblath (see Figure 1), the clinician should first evaluate the central nervous system causes for disorders of the brain and spinal cord. If these diseases are excluded, the clinician should next determine if the clinical presentation is consistent with acquired or hereditary peripheral neuropathy. If both central and peripheral nervous system involvement is indicated, the clinician may need to include mitochondrial disorders in the differential evaluation. Acquired peripheral neuropathy can be caused by diabetes, toxic exposure, drug interactions, autoimmune diseases and alcoholism. If the clinician is able to exclude the common causes of peripheral neuropathy, DNA and autoimmune testing can play a critical role in making a diagnosis in cases of suspected hereditary or autoimmune peripheral neuropathies. Without the aid of DNA and autoimmune testing, about 30% of peripheral neuropathies remain idiopathic.

Extractions: HMSNL is a severe form of demyelinating CMT disease, associated with neural deafness in the majority of affected individuals. The diagnosis is based on: Clinical signs : Severe neuropathy with onset in the first decade of life, distally accentuated muscle weakness and wasting more pronounced in the lower limbs, foot and hand deformities. Hearing loss develops almost invariably in the 2nd-3rd decade; Electrophysiological signs : Nerve conduction velocities severely reduced in younger patients and usually unobtainable after age 15 years. Brainstem auditory evoked potentials (BAEPs) are markedly abnormal, with evidence of retrocochlear involvement of the central auditory pathways. Neuropathological signs : Severe reduction in myelinated fibre density and extensive endoneurial collagen deposition, increasing in severity with age. Abnormalities in the myelin sheath include uncompacted lamellae, abnormally oblique Schmidt-Lanterman incisures, and variable myelin thickness in adjacent internodes and complete demyelinisation of scattered internodes. Small onion bulb formations in younger patients gradually disappear with age. Active myelinated fibre degeneration is occasionally present in young patients. There is no evidence of regeneration of myelinated fibres, but the density of unmyelinated fibres is increased. Occasional demyelinated axons are packed with curvilinear profiles, similar to experimental vitamin E deficiency and dystorphic axons.
Extractions: Close Window Abstract: Two siblings, a 35-year-old male and a 37-year-old female, offspring of first cousins, presented with a hereditary motor and sensory neuropathy with type I clinical features which began to manifest at about age 10 years. Nerve biopsy in the proband showed it to be a type characterized by excessive myelin outfolding. Morphometric study revealed hypomyelination with focal thickenings due to outfoldings. Clinical, electrophysiological and morphological findings are virtually identical to those described by Ohnishi et al. The peculiarity of the neuropathological picture suggests a particular form of hereditary motor and senory neuropathy. Can. J. Neurol. Sci. 1994; 21: 29-33
Extractions: The association of hereditary spastic paraplegia and hereditary motor and sensory neuropathy in the same family Münife Müftüoðlu , M.D., Ý. Özcan Ertürk , M.D., Cemal Özcan , M.D., Hakan Ekmekçi , M.D. The association of hereditary spastic paraplegia (HSP) and sensory neuropathies have been reported in a number of cases. But it is rare to detect both entities seperately in different members of the same family. In the present study, we report clinical and electrophysiological findings of three members of a family. In two of the siblings the clinical picture was indistinguishable from "pure" hereditary spastic paraplegia, but electrophysiological studies revealed a predominantly sensory polyneuropathy. In the third case (the mother of the siblings), the clinical diagnosis was consistent with hereditary motor sensory neuropathy type 2, which was also confirmed by electrophysiological studies. We believe that, with the further genetic reevaluations, the hereditary spastic paraplegia with sensory abnormalities may take a new place in the classification of hereditary motor and sensory polyneuropathies, as a distinct entity.[Journal of Turgut Özal Medical Center 2(2):193-195,1995] Key Words : Hereditary spastic paraplegia, hereditary motor and sensory neuropathy

EMG EMG CASE No. 59, January 2003, continued History A 13-year-old African American boy was admitted to the hospital for swelling of the left knee. This started 3 months earlier after having jumped from the second story of a building. There was a significant delay in seeking medical attention. He had been in foster care for the last 11 years for reported neglect, physical and sexual abuse on several occasions. The child had a longstanding history of behavioral problems and self-mutilation. His medical history consisted of numerous injuries including electrical burns and scalds on the hands, face, torso, and lower extremities, some of which required skin grafting. Around the age of 3 years, he developed ataxia and an occipital headache. An MRI revealed Arnold-Chiari Type I malformation. He was treated with a suboccipital craniectomy and C1 laminectomy. Prior to continuing, please develop a differential diagnosis and list each possible diagnosis in order of likelihood.
