Here, we describe a patient with multifocal motor neuropathy, who developed RLS during the course of the disease. Our findings ...

Heredoataxias are a group of genetic disorders with a cerebellar syndrome as the leading clinical manifestation. The current classification distinguishes heredoataxias according to the trait of inheritance into autosomal dominant, autosomal recessive, X-linked, and maternally inherited heredoataxias. The autosomal dominant heredoataxias are separated into spinocerebellar ataxias (SCA1-8, 10-15, 17-23, 25-30, ...

Hereditary hemorrhagic telangiectasia (HHT), Osler-Weber-Rendu Syndrome, is an uncommon disease but may be present in many people who remain undiagnosed. It is an autosomal dominant disorder characterized by multiple arteriovenous malformations (AVMs) and telangiectases that affect multiple organ systems. Hereditary hemorrhagic telangiectasia patients have a propensity for bleeding, especially from ...

Thiamine responsive megaloblastic anemia syndrome (TRMA) is a clinical triad characterized by thiamine-responsive anemia, diabetes mellitus and sensorineural deafness. We report a 4-year-old girl with TRMA whose anemia improved following administration of thiamine and this case report sensitizes the early diagnosis and treatment with thiamine in children presenting with anemia, ...

Classification of neuropathies into Charcot-Marie-Tooth syndrome (CMT, hereditary motor and sensory neuropathy) or purely motor neuropathies is relatively easy in single patients but subtle sensory findings can vary in different affected individuals in a family. We examined the extent of sensory involvement in different individuals in two new X-linked neuropathy ...

ABSTRACT: Hereditary spherocytosis (HS) is a genetic disorder of the red blood cell membrane clinically characterized by anemia, jaundice and splenomegaly. Evans' syndrome is a clinical syndrome characterized by autoimmune hemolytic anemia (AIHA) accompanied by immune thrombocytopenic purpura (ITP). It results from a malfunction of the immune system that produces ...

Research and development in the area of paraproteinemic demyelinating peripheral neuropathy is slower than for some of the other inflammatory neuropathy syndromes. However, 2007-2008 has produced developments in the understanding of the pathogenesis of the neuropathy and the paraprotein, a potential new animal model, easier diagnostics, and two randomized controlled ...

Familial colorectal adenocarcinoma (CRC) accounts for approximately 15 to 20% of CRC. Of these, hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP) represent the most common hereditary syndromes associated with CRC, followed by other less common diseases including juvenile polyposis (JP) and Peutz-Jeghers syndrome (PJS). Extracolonic manifestations are ...

Mycoplasma pneumonia (MP) is mainly associated with cold agglutinin syndrome, whereas both cold IgM and warm IgG autoantibodies have been identified in only two cases in the literature. The authors present an 8-year-old boy with Down syndrome, who suffered from recurrent episodes of MP infection, followed by episodes of hemolytic ...

Hereditary myelopathies are a diverse group of disorders in which major aspects of the clinical syndrome involve spinal cord structures. Hereditary myelopathic syndromes can be recognized as four clinical paradigms: (1) spinocerebellar ataxia, (2) motor neuron disorder, (3) leukodystrophy, and (4) distal motor-sensory axonopathy. This review illustrates these hereditary myelopathy ...

We report a 36-year-old patient with 46XY pure gonadal dysgenesis (GD), who manifested a syndrome of progressive motor-sensory neuropathy. Sural nerve biopsy showed severe axonal neuropathy. Since reported cases of chronic motor-sensory neuropathy and pure gonadal dysgenesis have been characterized by nerve biopsy evidence of minifascicle formation, we suggest that ...

Phaeochromocytomas are rare neuroendocrine tumours that produce catecholamines and numerous secretory proteins and peptides, including neuropeptide Y (NPY), a vasoactive peptide with influences on blood pressure. The production of catecholamines and NPY by phaeochromocytomas is highly variable. This study examined influences of hereditary factors and differences in catecholamine production on ...

Hereditary spherocytosis is an autosomal dominant familial hemolytic disorder due to the abnormality of the erythrocyte membrane. We report a case of nephrotic syndrome due to membranoproliferative glomerulonephritis in a patient with hereditary spherocytosis.

A 56-year-old man presented with sudden-onset oropharyngeal dysphagia and vomiting of central etiology. Neurological evaluation showed uvula deviation to the left, paresis of the mid-right portion of the soft palate, lateralization of gaze to the right side, and dysphonia. Magnetic resonance imaging (MRI) showed an infarction in the left lateral ...

Blepharismone (gamone 2) is a mating-inducing pheromone of the ciliate Blepharisma japonicum. N-Pyrenylbutyryl-blepharismone and N-biphenylacetyl-blepharismone, which are fluorescent derivatives of blepharismone, were synthesized as molecular probes for the gamone 2 receptor. Further, we proved that they have inhibitory activities against the blepharismone-induced monotypic pairing of B. japonicum.

Peripheral neuropathies constitute an important group of disorders in neurological practice. Very few systematic studies on peripheral neuropathies are available from India. Hence we conducted a prospective study in two large hospitals from Kolkata, the biggest city of eastern India in order to find out the spectrum of peripheral neuropathy. ...

Spinocerebellar ataxia 25 (SCA25) is a rare form of autosomal dominant cerebellar ataxia associated with a severe sensory neuropathy. Clinical variability ranges from incomplete penetrance at age 61 to a Friedreich ataxia-like syndrome. The responsible locus was mapped to chromosome 2p in a large region of 14 Mbases in a ...

Hereditary hyperferritinaemia-cataract syndrome (HHCS) is a rare differential diagnosis of hereditary haemochromatosis. It should be suspected in patients with raised ferritin levels, but no evidence of iron overload, and in the absence of mutations in the HFE gene. Awareness of this condition prevents unnecessary liver biopsies and allows accurate genetic ...

A case of bilateral synovial osteochondromatosis in a patient with hereditary arthro-ophthalmopathy is presented. The osteochondral lesions were largely calcified in one joint and largely chondromatous in the other. Typical features of hereditary arthro-ophthalmopathy are reviewed and it is hypothesised that the abnormal collagen in this syndrome is responsible for ...

Leber's hereditary optic neuropathy is a mitochondrial disease caused by point mutations in mitochondrial DNA. It usually presents as severe bilateral visual loss in young adults. We report on a neurological disorder resembling Leigh syndrome, which complicated Leber's hereditary optic neuropathy in three unrelated male patients harboring mitochondrial DNA mutations ...

The distribution and clinical appearance of the telangiectasia in the CREST syndrome (calcinosis, Raynaud's phenomenon, oesophageal involvement, sclerodactyly, telangiectasia) and hereditary haemorrhagic telangiectasia (HHT) are very similar. Several previously reported cases of the CREST syndrome simulating HHT illustrate this diagnostic quandary. We report a patient who met the diagnostic criteria ...

Cerebellar ataxia and hypergonadotropic hypogonadism comprise a rare and presumably heterogeneous association. Inheritance in most cases appears to be autosomal recessive, and associated features include deafness, intellectual impairment, and neuropathy. Typically, onset of ataxia is in the first decade and hypogonadism results in primary amenorrhoea in females. We describe two ...

A series of polyacetylenes, falcarinone, panaxynol, falcarindiol, panaxydol, and panaxytriol, were isolated from Saposhnikovia divaricata (Turcz.) Schischk and Panax quinquefolium L. These polyacetylenes were identified as active principles on the inhibition of nitrite production by inducible nitric oxide synthase (iNOS). Treatment with 10 microM of panaxynol, falcarindiol, panaxydol and panaxytriol ...

Paraneoplastic neuropathies occur in various settings. This article focuses on recent neuroimmunologic findings regarding paraneoplastic neuropathy. Entities such as sensorimotor and sensory neuropathy, sensory neuronopathy; motor, autonomic, demyelinating and vasculitic mononeuropathies; and cranial nerve lesions and neuropathies in association with leukaemia and paraproteinaemas are discussed. Finally, the article considers the ...

Previous clinical studies only described epilepsy and EEG abnormalities in patients with hereditary nephritis (Alport syndrome). In this paper, brain MR imaging findings in a 10-month-old boy with hereditary nephritis are described. These included patchy and nodular lesions in the thalami and basal ganglia, and retarded white matter myelination. The ...

Hereditary lymphedema can appear at birth or later up to adulthood. It may be seen in connection with diverse symptoms forming various syndromes. The authors report a family with hereditary lymphedema, brachydactyly, syndactyly and tachycardia. Lymphedema and tachycardia could appear together by chance. However this combination could also be a ...

Autoimmune ataxic neuropathies are a subset of the sensory ataxic neuropathies which are characterized by ataxia as the dominant presenting feature. The major known causes of autoimmune ataxic neuropathies include sensory variants of the Guillain-Barré syndrome, including Miller-Fisher syndrome, subsets of immunoglobulin M paraproteinaemic neuropathy, paraneoplastic neuropathy and the neuropathy ...

We report on the vaginal mucosal folds (VMF) at the urethral external meatus. Resection of the VMF reduces the dispersed micturition and other urinary symptoms.

Hereditary osteo-onychodysplasia, also known as the nail-patella syndrome (NPS), consists of a clinical tetrad of nail dysplasia, hypoplastic or absent patella, radial head dislocation, and iliac horns. Bilateral posterior iliac horns are observed only in NPS and present in >80% of patients. We describe the appearance, location, and structure of ...

The association between hereditary motor and sensory neuropathy (HMSN) and optic atrophy has been termed HMSN type VI. The autosomal dominant inheritance of this syndrome is reported. Three generations were affected with optic atrophy, which differed in some respects from classic dominant optic atrophy, and an asymptomatic, mainly sensory, neuropathy.

Hereditary haemochromatosis is characterised by excessive parenchymal iron deposition, particularly in the liver. Usually hereditary haemochromatosis is not associated with neurological symptoms and iron deposition in the brain has not previously been described as a pathological phenomenon. A patient is reported with hereditary haemochromatosis and a syndrome of dementia, dysarthria, ...

The first case of hereditary chondrodysplasia ("spider syndrome") in a New Zealand Suffolk lamb of American origin is described. An imported Suffolk ram of American origin was test mated to 27 of his daughters. In one of the resulting progeny, found dead at birth, a diagnosis of hereditary chondrodysplasia was ...

Neurochemical investigations of Tourette's syndrome (TS) suggest that the symptoms of this disorder may be the result of an imbalance among several neurotransmitter and/or neuromodulator systems. Neurochemicals which have been studied included: catecholamines; acetylcholine; tryptophan and its metabolites; the amino acids γ-aminobutyric acid (GABA), glutamate, phenylalanine and p-tyrosine; trace amines; ...

In three generations of a family investigation for coexpression of May-Hegglin anomaly and hereditary nephritis was done by routine studies, as well as electron microscopy of renal tissue and blood cells, platelet aggregation studies, audiograms, and ophthalmologic evaluations. The propositus had typical May-Hegglin anomaly and a mild form of hereditary ...

Chromatographic assay of n-alkanes in skin showed detectable levels in normal controls and in patients with various forms of hereditary ichthyosis. Raised n-alkanes were found in some, but not all, patients with non-bullous and bullous ichthyosiform erythroderma and in individual patients with lamellar ichthyosis, ichthyosis vulgaris and Netherton's syndrome. The ...

Hereditary gingival fibromatosis is frequently an isolated condition of little consequence apart from a cosmetic problem and occasional associations with hypertrichosis and/or epilepsy. There are, however, several uncommon or rare eponymous syndromes described in which gingival fibromatosis can be a feature: these include the Zimmermann-Laband, Murray-Puretic-Drescher, Rutherfurd, Cowden and Cross ...

A New Zealand family with 3 members affected by late onset hereditary cerebellar ataxia is reported, distinguished by the development of near global thermoanalgesia. Because proprioception and autonomic function were preserved, and ataxia only slowly worsened, this proved to be a benign syndrome. The pattern of sensory loss indicated a ...

Subcutaneous injections of a 5-HT1A receptor agonist, 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), in monkeys induced distinct behavioural changes characterized by head weaving, hindlimb extension and upper limb fluttering. The effects were dose-dependent and were similar to the 5-HT syndrome induced in rats by 8-OH-DPAT. The 5-HT receptor antagonist, metergoline, attenuated the behavioural syndrome ...

The hereditary neuropathies, representing up to 20 per cent of the total of peripheral neuropathies, present a considerable problem in neurology, rehabilitation medicine, and orthopedics. Patients have predominant foot abnormalities such as pes cavus and talipes equina varus. The largest section is the Charcot-Marie-Tooth syndrome or peroneal muscular atrophy, followed ...

We present two patients, a mother and son, with Alport's syndrome (hereditary nephritis and perceptive deafness). Only the son had the typical lenticonus and perimacular flecks. Both patients had macular degeneration, the clinical manifestation of which resembled that seen in cone dystrophy. Colour vision was affected, the cone-mediated b-wave implicit ...

Hereditary forms of carcinoma may be associated with benign head and neck tumors. Many of these hereditary carcinoma syndromes present first to the otolaryngologist. Two unusual cases of Gardner's and Muir--Torre's syndromes illustrate the hereditary carcinoma syndromes associated with head and neck lesions. We describe the use of new genetic ...
