Miller Fisher syndrome (MFS) is characterised by ophthalmoplegia, ataxia and areflexia. Reports on cerebellar ataxia and supranuclear oculomotor derangement in MFS suggested an additional involvement of the central nervous system (CNS), resembling Bickerstaff's brainstem encephalitis (BBE). In the present report, a patient with a monophasic acute illness, early recovery and specific clinical-laboratory findings suggested both intrinsic brainstem and peripheral nerve disease (MFS and BBE). In pons and medulla oblangata, blurred to discrete T2-lesions were revealed by cranial MRI, while involvement of peripheral nerves was detected with EMG. The CSF showed no increase in protein or cell content, such as occurs in brainstem encephalitis.

Some inflammatory diseases of the gastrointestinal system are associated with neurological symptoms which, in rare cases, may precede the onset of the gastrointestinal manifestation of the disease. Celiac sprue is characterized by an intolerance to the wheat protein gluten. The typical neurological manifestation of celiac sprue is cerebellar ataxia. The ataxia as well as the gastrointestinal symptoms can be treated with a strictly gluten-free diet. The neurological symptoms of Whipple's disease, a disorder caused by gram-positive bacilli, are variable. Typical symptoms of cerebral Whipple's disease include dementia, ophthalmoplegia, movement disorders, and signs of hypothalamic dysfunction. Nowadays, the diagnosis of cerebral Whipple's disease is made by PCR detection of the bacilli in the CSF. Crohn's disease and ulcerative colitis are associated with neurological symptoms to a similar proportion. Various forms of polyneuropathies have been observed. The CNS manifestations of inflammatory bowel diseases include thromboembolic stroke, cerebral venous thrombosis, and cerebral vasculitis.

Machado-Joseph disease (MJD) is a dominantly inherited cerebellar ataxia associated with spasticity, ophthalmoplegia, dystonia and peripheral neuropathy. Presented here are 5 MJD cases. A morphometric analysis of the histopathology of their sural nerves was carried out to know the relationship between axon size and myelin thickness. MJD cases were identified by polymerase chain reaction. On the basis of the clinical symptoms, there was 1 type I, 2 type II and 2 type III patients. The sural nerves were biopsied for single-fiber, ultrastructural and morphometric analysis. Morphometric parameters such as fiber and axon sizes, myelin thickness and g ratio (axon diameter:fiber diameter) were estimated. The pathological features of the sural nerves in the 2 type III and 1 of the type II patients revealed a loss of myelinated and unmyelinated fibers, and the morphometry studies showed a decreased fiber density, the loss of large myelinated fibers, a smaller size of the axons with thinner myelin sheaths and an increased percentage of myelinated fibers with a g ratio (axon diameter:fiber diameter) above 0.7. However, only subtle pathological changes were noted in the type I patient and the remaining type II patient. Our findings suggested that there is a loss of large myelinated fibers and distal axonopathy with relative hypomyelination in the neuropathy of patients with MJD.

Behcet's disease is a multisystem vasculitis. Its neurologic complications include different syndromes. The purpose of this investigation was to study the prevalence of neurologic manifestations among patients with Behcet's disease and to determine the frequency of different symptoms, signs, and syndromes in neuro-Behcet's disease. Ninety-six consecutive patients who were referred to the Behcet's Disease Clinic in Shiraz (southern Iran) were interviewed and thoroughly examined. Psychiatric evaluation, CSF analysis, electroencephalography, electrodiagnostic studies, and neuroradiologic imaging (preferably MRI) were performed in appropriate cases. Six patients (6.3%) had definite neuro-Behcet's disease. They were 4 males and 2 females (mean age 37.5 years). In 2 patients Behcet's disease had not been diagnosed before. The most frequent symptoms of neuro-Behcet's disease were headache (83.3%), paresthesia (83.3%), unsteadiness (66.7%), diplopia (66.7%), and weakness (50%). The most frequent signs were gait abnormalities (66.7%), sensory abnormalities (66.7%), ophthalmoplegia (50%), cerebellar ataxia (50%), and hemiplegia (50%). The most common syndrome was brain-stem+ type (50%). Subacute onset and relapsing-remitting course were the most common temporal patterns. Neurological manifestation is a relatively less frequent complication of Behcet's disease but it produces severe disabilities. It must be considered in differential diagnosis of multiple sclerosis.

We report a 70-year-old woman with bilateral optic atrophy, external ophthalmoplegia, bilateral blepharoptosis, and sensory ataxic neuropathy. She had a visual disturbance since childhood. She had dysarthria and gait disturbance at 28 years old. She had bilateral blepharoptosis, marked gait disturbance and dysphagia at 50. On neurological examination, external ophthalmoplegia, bilateral blepharoptosis, mild weakness and muscular atrophy of promixal muscles, hyporeflexia, positive Romberg sign, glove and stocking type sensory disturbance including hypesthesia, hypalgesia, and bathyhypesthesia were found. She did not show pigmented retinopathy, cognitive dysfunctions, hearing loss, cerebellar ataxia, Hoffman reflex nor Babinski sign. She did not show increased lactic acid nor pyruvic acid in the cerebrospinal fluid but mild increase of pyruvic acid (1.0 mg/dl) in her serum. The conduction velocity and amplitude of CMAP of tibial nerve was 37.4 m/sec and 2.9 mV, respectively. The SNAP of ulner and sural nerve were not evoked. Brain MRI showed no pathological findings. Muscle biopsy from the biceps muscle showed many ragged-red fibers (5.3%) and some fibers with decreased or absent COX activity. Sural nerve biopsy showed a marked loss of large myelinated fibers with thin myelinated fibers, and onion-bulb formation. The clinical findings of our patient is similar to that of SANDO (the triad of sensory ataxic neuropathy, dysarthria, and ophthalmoparesis), however, large mtDNA deletion reported by Fadic in patients with SANDO was not found in our patient. It might be possible that her mtDNA deletion is small or point mutation is existed.

Niemann-Pick disease, type C (NPC) is a neurometabolic genetic disorder that is distinguished from other types of Niemann-Pick disease by its later onset, more insidious progression, variable visceromegaly, and abnormalities of intracellular cholesterol metabolism. We report cases in 18-year-old and 20-year-old brothers who presented with disinhibition and involuntary movement of their hands. Both brothers presented various signs such as dementia, vertical supranuclear ophthalmoplegia (VSO), dysarthria, axial and limb dystonia, hyperreflexia, pathologic reflex, cerebellar ataxia, as reported. They also presented startle response. Brain MRI showed diffuse cerebral atrophy and abdominal CT reveals hepato-splenomegaly in both patients. These cases were suspected to be NPC based on dementia, VSO, cerebellar ataxia, hepato-splenomegaly and foam cells in the bone marrow. Generally, the diagnosis of NPC is based on deficient cholesterol esterification and excessive lysosomal filipin staining in cultured skin fibroblasts. However, culture of fibroblasts obtained from a biopsied skin samples is slow. We have rapidly made the diagnosis of NPC in our patients by filipin staining of foam cells from bone marrow. This diagnostic process using a bone marrow smear is more convenient and rapid than previous methods using cultured skin fibroblasts.

Depletion and multiple deletions of mitochondrial DNA (mtDNA) have been associated with a number of autosomal disorders classified as defects of nuclear-mitochondrial intergenomic signaling. The mendelian forms of progressive external ophthalmoplegia (PEO) are clinically and genetically heterogeneous disorders characterized by the accumulation of multiple deletions of mtDNA in postmitotic patient's tissues. Most of the autosomal dominant PEO (adPEO) families carry heterozygous mutations in either one of three genes: ANT1, Twinkle, and POLG1. Mutations in POLG1 can also cause autosomal recessive PEO (arPEO) and apparently sporadic cases. In addition, recessive POLG1 mutations are responsible for sensory-atactic neuropathy, dysarthria and ophthalmoplegia (SANDO), juvenile spino-cerebellar ataxia-epilepsy syndrome (SCAE) and Alpers-Huttenlocher hepatopathic poliodystrophy. Mutations in thymidine phosphorylase gene (TP) are linked to mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), an autosomal recessive disorder in which PEO is associated with gastrointestinal dysmotility and leukodystrophy. Finally, mitochondrial DNA depletion syndromes (MDS), defined by tissue-reduction in mtDNA copy number, have been linked to mutations in two genes involved in deoxyribonucleotide (dNTP) metabolism: thymidine kinase 2 (TK2) and deoxyguanosine kinase (DGUOK).

We describe the novel association of spinocerebellar ataxia type 3/Machado-Joseph disease (SCA3/MJD) phenotype combining classical clinical presentation and semeiology mimicking stiff man syndrome (SMS). The studied pedigree comprises seven affected members in three generations. Their clinical picture consisted of cerebellar ataxia, pyramidal signs, facial myokymia, and ophthalmoplegia. The proband was a 39-year-old man in whom such a clinical picture, 5 years after onset at age 29, evolved to severe SMS and widespread myokymia. Electrophysiological study revealed continuous muscle activity in proximal limb muscles. Molecular study demonstrated the MJD gene mutation in all four examined patients with 73 to 76 CAG repeats in the expanded allele. We conclude that an excess of motor unit activity including stiff man-like syndrome and widespread myokymia may be an integral part of the SCA3 clinical spectrum.

Kearns-Sayre syndrome (KSS) is a mitochondrial encephalomyopathy characterized by progressive external ophthalmoplegia (PEO), pigmentary retinopathy and onset before the age of 20 years. Cerebellar ataxia, as well as short stature and increased protein content in the cerebrospinal fluid, are frequent additional symptoms. A single large mitochondrial (mt) DNA deletion of 4,977 bp is the most common molecular defect in KSS. Recently, different mutations have also been associated with incomplete, KSS-like phenotypes. We describe the unusual clinical presentation of a patient carrying a novel 1,814-bp deletion of mtDNA. In contrast with typical KSS, the clinical picture of this patient did not include either palpebral ptosis or PEO and was dominated by an ataxic syndrome.

Spinocerebellar ataxia type 14 (SCA14) is an autosomal dominant neurodegenerative disorder characterized by cerebellar ataxia and intermittent axial myoclonus. Various mutations have been found in the PRKCG gene encoding protein kinase C gamma in SCA14 families. Most of those mutations have been found in exon 4 of the PRKCG gene. We performed polymerase chain reaction (PCR)-based screening to clarify the approximate morbidity rate of the disease in the Japanese SCA population. We screened exon 4 of the PRKCG gene in 882 SCA patients with undefined etiologies using denaturing high-performance liquid chromatography and subsequent direct sequencing. We found a novel C/T missense mutation with a Ser119-to-Phe substitution (S119F) in 2 patients and subsequently found that they belonged to the same family. This S119F mutation was not found in 259 control individuals. Further PCR-based analysis revealed an additional 5 members with the same mutation in this family. Cerebellar ataxia was manifested in 5 of those 7 members. The main symptom in 4 of the 5 affected members was pure cerebellar ataxia with late onset. They had no myoclonus, extrapyramidal signs, ophthalmoplegia, or intellectual disturbance, some of which were found in previously reported SCA families. One patient showed intractable epilepsy, severe walking disturbance, and trunk ataxia with early onset. The results of this study suggest that the frequency of SCA14 in the Japanese SCA population is very low.
