In 2,000 consecutive stroke patients collected in a prospective hospital-based stroke registry over a 10-year period, we assessed whether stroke in men and women was different in respect to vascular risk factors, clinical features and natural history. The frequency of the different variable in men and women was analyzed by means of univariate analysis and logistic regression models. Women accounted for 48% of the study population (n = 967) and were older than men (mean age 75 vs. 69 years, p < 0.001). In the age group of 85 years or older, stroke was more frequent in women than in men (69.8 vs. 30.2%, p < 0.001). Women showed a higher frequency of cardioembolic infarction and a lower occurrence of lacunar infarction and stroke of undetermined cause than men. In-hospital mortality (17.4 vs. 13.3%) and length of hospital stay (19.6 vs. 16.7 days) was significantly higher (p < 0.001) in women than in men. In the model based on demographic variables and cardiovascular risk factors, obesity, heart failure, atrial fibrillation and age were significant predictors of stroke in women, while intermittent claudication, ischemic heart disease, chronic obstructive pulmonary disease, cigarette smoking and alcohol abuse were predictors in male sex. Hypertension and limb weakness were predictors for stroke in women, and absence of neurological deficit at hospital discharge, lacunar syndrome and ataxia were predictors in men in the models based on all variables. Women differ from men in the distribution of risk factors and stroke subtype, stroke severity and outcome. Differences in stroke pathology and/or differences in functional anatomy or plasticity of the brain between sexes may account for these findings.

Bardet-Biedl syndrome (BBS) and Laurence-Moon syndrome (LMS) have a similar phenotype, which includes retinal dystrophy, obesity, and hypogenitalism. They are differentiated by the presence of spasticity and the absence of polydactyly in LMS. The aims of this study were to describe the epidemiology of BBS and LMS, further define the phenotype, and examine genotype-phenotype correlation. The study involved 46 patients (26 males, 20 females) from 26 families, with a median age of 44 years (range 1-68 years). Assessments were performed in 1986, 1993, and 2001 and included neurological assessments, anthropometric measurements, and clinical photographs to assess dysmorphic features. The phenotype was highly variable within and between families. Impaired co-ordination and ataxia occurred in 86% (18/21). Thirty percent (14/46) met criteria for psychiatric illness; other medical problems included cholecystectomy in 37% (17/46) and asthma in 28% (13/46). Dysmorphic features included brachycephaly, large ears, and short, narrow palpebral fissures. There was no apparent correlation of clinical or dysmorphic features with genotype. Two patients were diagnosed clinically as LMS but both had mutations in a BBS gene. The features in this population do not support the notion that BBS and LMS are distinct. The lack of a genotype-phenotype correlation implies that BBS proteins interact and are necessary for the development of many organs.

We report on two sisters with a childhood-onset form of predominantly axial dystonia with marked diurnal fluctuations. Onset of clinical features was at approximately 6 years of age. Associated features included marked fatigue, slight facial dysmorphism, short stature, obesity, and learning disability*. Dystonia and fatigue responded to 3,4-dihydroxyphenylalanine (DOPA) therapy, with recurrence of symptoms upon withdrawal; the efficacy has been maintained over 7 years. Other symptoms were not influenced. There was no other case in the family (which included an older, healthy brother), except for non-specific fatigue without dystonia in the mother, and there was no significant family history except for obesity on the father's side. These observations are discussed in relation to the classical descriptions of Segawa syndrome, and to more recent reports of childhood onset, age-related, and transient benign paroxysmal tonic upgaze and ataxia. The combination of symptoms, their sensitivity to DOPA, and their persistence throughout childhood constitute, to our knowledge, a new clinical entity, which we propose to categorize as a DOPA-sensitive dystonia-plus syndrome.

A 12-year-old boy with mental retardation, obesity, ataxia, and visual impairment was shown to have normal fasting plasma triglyceride but low cholesterol and vitamin E levels. Investigations indicated that he was compound heterozygous for two mutations in the apolipoprotein B gene (APOB), resulting in a failure to express apolipoprotein B-100, yet retain apolipoprotein B-48 production. The proband therefore was able to form chylomicrons, but not a low-density lipoprotein capable of receptor-mediated endocytosis. This resulted in chronic vitamin E deficiency. We suggest the term normotriglyceridemic hypobetalipoproteinemia for this easily recognizable condition.

This article attempts to describe a very unusual case of a boy aged 15, who has had intractable epileptic phenomena, mental retardation, megalocephaly, micrognathy, syndactyly, small tongue, hypoplastic genitalia, gynecomasty, obesity, and slight left body hemiatrophy. Neurologically the patient has had hypotonia of the lower limbs, cerebellar dysfunction including horizontal nystagmus, bilateral intention tremor, dysdiadokokinesia, gait ataxia. The clinical investigation revealed low plasma cholesterol and hypoplasia of the vermis in MRI. The epileptic phenomena were intractable and polymorphous. One should have thought that this is an unusual case of Smith-Lemli-Opitz syndrome associated with features of Joubert syndrome.

We describe an Egyptian family having SCA2 affecting three generations with marked molecular and clinical anticipation observed in the index case. Our proband was a male child starting as early as 2 years old with progressive extrapyramidal manifestations, slow eye movements and cognitive impairment. A history of nonspecific mild developmental delay was recorded. The patient lost all cognitive functions, had persistent dystonic posture, trophic changes, vasomotor instability, dysphagia and died at the age of 7 years. The age at presentation among other affected family members varied between 11 and 45 years old across three generations. The early common neurological symptoms were choreoathetotic movements, myoclonic jerk, gait difficulty, expressionless face and emotional liability. Later, overt ataxia, incoordination, dysarthria, mild dementia and slow eye saccades predominated. Brisk tendon reflexes were detected in three cases. Peripheral nerve affection was a late manifestation. Interestingly, polyphagia and obesity were striking manifestations in the middle stage of the disease; an observation that might support a previously suggested relation between the ataxin-2 gene and body weight. The proband showed an amplified allele with marked CAG expansion in the form of a smear sized 69-75 repeats resulted from maternal transmission. To our knowledge, our index case is the second report in the literature presenting with infantile onset SCA2 and intermediate repeat expansion. This family expands the phenotypic spectrum of early onset SCA2 and points out the importance of considering SCA2 gene analysis in children with progressive neurological impairment and abnormal movements with or without polyphagia.

We describe a 10-year-old boy with an intracranial lipoma in the posterior fossa. The patient had a subcutaneous tumor of the posterior neck at birth, which was gradually growing and subsequently accompanied by gait disturbance and ataxia. MR imaging revealed the intracranial lipoma in the posterior fossa extending into the cervical spinal canal and subcutaneous space via a cranium bifidum. A surgical operation was performed, but the lipoma could not be removed completely. He had had prominent obesity that might have caused not only enlargement of the intracranial lipoma but also neurological complications. Although intracranial lipomas are usually benign and asymptomatic, early detection of them is quite critical, and body weight control may help to prevent their progression.

Wernicke's encephalopathy (WE) is one of the potential complications of obesity surgery. It is an acute neuropsychiatric syndrome resulting from thiamine deficiency often associated with repeated vomiting. The classic triad is frequently reported in these patients (optic neuropathy, ataxia and confusion), associated with uncommon features. Cerebral impairment affects the dorsal medial nucleus of the thalamus and the periaqueductal grey area, appearing on MRI, as hyperintense signals on T2, Flair and Diffusion weighted imaging. Early diagnosis and parenteral thiamine are required to decrease morbidity and mortality. We report a case of WE and Korsakoff's syndrome in a young obese patient after subtotal gastrectomy, who still has substantial sequelae. The contribution of MRI with diffusion-weighted imaging is illustrated. The interest of nutritional supervision in the first weeks and preventive thiamine supplementation in case of repeated vomiting are of particular importance in these risky situations.

A 2-year-old, castrated male, Australian shepherd was presented with a history of chronic mild ataxia, obesity, and lethargy. The dog was treated with levothyroxine, but the ataxia worsened. Cranial nerve abnormalities developed and the dog was euthanized. Postmortem examination revealed marked thyroid gland atrophy and widespread, severe central nervous system atherosclerosis.

Many studies have focused on the behavior and cognitive problems in young patients with fragile X syndrome (FXS), but there are no studies about the problems in aging for those with FXS. The discovery of the fragile X-associated tremor ataxia syndrome (FXTAS), a neurodegenerative disorder related to elevated FMR1-mRNA, in elderly men and some women with the premutation, intensified the need for aging studies in FXS. Approximately 40% of males with FXS have repeat size mosaicism and as a result, some of these individuals also have elevated levels of FMR1-mRNA which theoretically puts them at risk for FXTAS. Here, we have surveyed all of the aging patients with FXS that we have followed over the years to clarify the medical complications of aging seen in those with FXS. Data was collected from 62 individuals with the FXS full mutation (44 males; 18 females) who were at least 40 years old at their most recent clinical examination. We found that the five most frequent medical problems in these patients were neurological problems (38.7%), gastrointestinal problems (30.6%), obesity (28.8%), hypertension (24.2%) and heart problems (24.2%). Movement disorders were significantly different between males and females (38.6% vs.10.2%, p = 0.029). We did not find any differences in medical problems between those with a full mutation and those with mosaicism. Identification of medical problems associated with aging in FXS is important to establish appropriate recommendations for medical screening and treatment considerations.
