The findings in 44 patients (42 of whom were chronic alcoholics) with central pontine myelinolysis show that the outcome does not depend on the severity of neurological deficits during the acute phase of the condition or on concomitant internal diseases, including the degree of hyponatremia. Of the 34 patients for whom follow-up data were available, 32 survived. Of these 11 completely recovered, 11 had some deficits but were independent, and 10 were dependent (4 through disorders of memory or cognition, 3 with tetraparesis, 2 with cerebellar ataxia, 1 with polyneuropathy). The electrophysiological findings did not contribute usefully to the prediction of outcome. Additional neuroradiological diagnostic testing with magnetic resonance imaging was also of no prognostic significance. The extent of the initial pontine lesion was not correlated with the severity of clinical findings during the acute phase of disease, nor was persistence of the pontine lesion as usually seen on magnetic resonance imaging correlated with clinical improvement. We conclude that patients with cerebral myelinolysis survive if the nonspecific secondary complications of transient illnesses such as aspiration pneumonia, ascending urinary tract infection with subsequent septicemia, deep venous thrombosis, and pulmonary embolism can be avoided.
Multiple sclerosis (MS) is the most frequent chronic neurological disease affecting young persons in developed countries. MS is, however, considered as a secondary cause, of central origin, for autonomic dysfunction. The most common autonomic symptoms in MS are disorders of micturation, impotence, sudomotor and gastrointestinal disturbances, orthostatic intolerance as well as sleep disorders. The majority of the patients suffer at some period of the disease from lower urinary tract symptoms and sexual dysfunction. Awareness and treatment of these conditions is vital to improving health and quality of life in patients with MS. The increased understanding of the pathophysiological mechanisms in autonomic dysfunction in MS, along with technological and pharmaceutical developments has advanced our ability to treat the multiple aspects complicating autonomic failure in MS.
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy' (CADASIL) has recently been identified as a hereditary disorder with characteristic fine structural changes of small intracerebral arteries and arterioles. Electron microscopically there are characteristic perivascular deposits of granular electron-dense material resembling immunoglobulin deposits. The present case from a family with four affected members in three successive generations shows that similar vascular changes as described in the central nervous system are present in blood vessels of the sural nerve, although less pronounced and, therefore, affording electron microscopy for their unequivocal detection. Nevertheless it has been shown for the first time that the diagnosis of CADASIL can be verified by a sural nerve biopsy. Occasional focal accumulation of pinocytotic vesicles opposite the granular deposits suggests exocytosis as one of the possible pathomechanisms for their production.
Management of AS aims at the social reintegration of patients or has to guarantee humanistic active nursing if treatment fails. Outcome depends on the cause and duration of AS/VS as well as patient's age. There is no single AS/VS specific laboratory investigation, no specific regimen or stimulating intervention to be recommended for improving higher cerebral functioning. Quality management requires at least 3 years of advanced training and permanent education to gain approval of qualification for AS/VS treatment and expertise. Sine qua non areas covering AS/VS institutions for early and long-term rehabilitation are required on a population base (prevalence of 2/100.000/year) to quicken functional restoration and to prevent or treat complications. Caring homes are needed for respectful humane nursing including basal sensor-motor stimulating techniques. Passive euthanasia is considered an act of mercy by physicians in terms of withholding treatment; however, ethical and legal issues with regard to withdrawal of nutrition and hydration and end of life discussions raise deep concerns. The aim of the guideline is to provide management guidance (on the best medical evidence class II and III or task force expertise) for neurologists, neurosurgeons, other physicians working with AS/VS patients, neurorehabilitation personnel, patients, next-of-kin, and health authorities.
Recent studies have shown that preferences for close relationships (Long-Term Relationship Orientation) are independent of preferences for various sexual partners (Short-Term Relationship Orientation). In the current studies, we hypothesized that Short-Term Relationship Orientation would be negatively related to 2D:4D finger-length ratio (i.e., the more masculine, the higher Short-Term Relationship Orientation). Study 1 found a negative relationship between Short-Term Relationship Orientation and right, but not left, hand 2D:4D among 91 male participants. Study 2 found a negative relationship between Short-Term Relationship Orientation and left, but not right, hand 2D:4D among 65 male participants, even after controlling for age, relationship status, social desirability, and sex drive. Female participants (n = 142) did not show this relationship in Study 2. This sex difference was discussed in terms of flexible female sexual strategies, which are supposed to be contingent on the local environment or menstrual cycle variations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
