Cognitive Reserve alludes to gain, resistance, plasticity and is the functional correlative of neuroplasticity and a potential protection factor, which could explain why some patients may show the same pathology but quite different clinical manifestations. Among the activities considered as promoters are studies, work, physical and social activities. Although there are surveys or tables that seek to measure these factors and reflect this reserve in an index, this can be a quite reductionist strategy. Given the increasing ageing of the population, added to the active elders paradigm, programs addressed to seniors are carried out; it is important to consider that gains are accumulative and dynamism must be promoted from earlier ages. The sample for this work consisted of 30 seniors (60–87years) from the Region of Valparaíso, Chile. The CRIq was applied to the participants to measure the CR index and no differences were found between men and women. The purpose of this work is to describe the activities that promote reserve, carried out from 18 years onwards by 30 autonomous and cognitively competent seniors. It is held that it is not the type of activity that matters, but rather the frequency and the length of the execution period that turns into advantages for the persons. The data submitted reveal that seniors never failed to frequently execute some of the activities. That is, they had the habit of being active along their whole lives. This mechanism could be considered as a kind of dynamo where the greater input of promoting activities would make possible better conditions of the nervous system, but it does not have an easy storage as it is in continuous use. For this reason, gains depend on the active habit of execution, its early start, diversity of activities and permanence during the whole life span.

Introduction: Viral encephalitis accounts for 40-70% of all cases worldwide, central nervous system infections pose a diagnostic challenge because clinical manifestations are not typically pathognomonic for specific pathogens, and a wide range of agents can be causative. The aim: To assess the diagnostic value of intrathecal synthesis of specific antibodies in patients with inflammatory lesions of the central nervous system. Materials and methods: Within the framework of the study, two groups of 90 people in each were formed from the patients with neuroinfections admitted to our Center. Intrathecal synthesis (ITS) of total (unspecific) IgG in members of one of group (group of compare) was determined. Brain synthesis of specific antibodies (Ab) to some neurotropic pathogens (herpes simplex virus 1/2, cytomegalovirus, Epstein-Barr virus, varicella zoster virus, rubella virus, Borrelies) was studied in the second group of patients (group of interest). There were no statistically significant differences between groups by gender and age. Encephalitis and encephalomyelitis prevailed among patients of both groups Results: ITS of total IgG was established in 30 (33.3 ± 6.1 %) patients of the first group with IgG index more than 0.6 indicating on inflammatory process in CNS and no marked changes of CSF. ITS of specific Ab was determined in 23 of 90 (25.6 ± 4.6 %) patients included into group of interest. In more than half of cases Ab to several infectious agents were detected simultaneously. ITS of various specificity, in particular, to measles and rubella viruses, and VZV, known as MRZ-reaction, is characteristic of some autoimmune lesions of CNS, multiple sclerosis first of all. In fact, further research of 5 patients with MRZ-reaction confirmed their autoimmune failure of CNS. Detection of ITS in the CSF samples didn’t depend on concentration of specific Ab in serum and CSF and wasn’t followed by HEB dysfunctions which were observed with the same frequency in patients with or without ITS (13.0 % and 13.6 % respectively). Conclusion: Specific Ab synthesis to several neurotropic pathogens in the CSF of significant part of examined patients was established. Thus, diagnostic value of ITS of specific immunoglobulins seems to be limited to cases in which autoimmune damage of the CNS is suspected.

The acute oral and dermal toxicity of two new ethyl-carbamates (ethyl-4-bromophenyl-carbamate and ethyl-4-chlorophenyl-carbamate) with ixodicide activity was determined in rats. The oral LD50of each carbamate was 300 to 2000 mg/kg, and the dermal LD50of each carbamate was >5000 mg/kg. Clinically, the surviving rats that had received oral doses of each carbamate showed decreased weight gain (P<0.05) and had slight nervous system manifestations. These clinical signs were evident from the 300 mg/kg dose and were reversible, whereas the 2000 mg/kg dose caused severe damage and either caused their death or was motive for euthanasia. At necropsy, these rats had dilated stomachs and cecums with diffuse congestion, as well as moderate congestion of the liver. Histologically, the liver showed slight degenerative lesions, binucleated hepatocytes, focal coagulative necrosis, and congestion areas; the severity of the lesions increased with dosage. Furthermore, an slight increase in gamma-glutamyltransferase, lactate dehydrogenase, and creatinine was observed in the plasma. The dermal application of the maximum dose (5000 mg/kg) of each carbamate did not cause clinical manifestations or liver and skin alterations. This finding demonstrates that the carbamates under study have a low oral hazard and low acute dermal toxicity.

Interindividual Differences

Abstract Objectives Interindividual differences in cognitive aging may be explained by differences in cognitive reserve (CR) that are built up across the life span. A plausible but underresearched mechanism for these differences is that CR helps compensating cognitive decline by enhancing motivation to cope with challenging cognitive situations. Theories of motivation on cognition suggest that perceived capacity and intrinsic motivation may be key mediators in this respect. Method In 506 older adults, we assessed CR proxies (education, occupation, leisure activities), motivation (perceived capacity, intrinsic motivation), and a global measure of cognitive functioning. Results Perceived capacity, but not intrinsic motivation, significantly mediated the relation between CR and cognitive performance. Discussion Complementary with neurobiological and cognitive processes, our results suggest a more comprehensive view of the role of motivational aspects built up across the life span in determining differences in cognitive performance in old age.

Neurofibromatosis, which was first described in 1882 by Von Recklinghausen, is a genetic disease characterized by a neuroectodermal abnormality and by clinical manifestations of systemic and progressive involvement which mainly affect the skin, nervous system, bones, eyes and possibly other organs. The disease may manifest in several ways and it can vary from individual to individual. Given the wealth of information about neurofibromatosis, we attempted to present this information in different ways. In the first part of this work, we present a chronological history, which describes the evolution of the disease since the early publications about the disorder until the conclusion of this work, focusing on relevant aspects which can be used by those wishing to investigate this disease. In the second part, we present an update on the various aspects that constitute this disease.

A disorder of copper metabolism at Wilson’s disease (WD), conditioned by a mutation of adenosine thriphospate P-type gene (ATP7B), results in irreversible changes in the liver and in the nervous system. Mortality is high at WD, but it is one of hereditary diseases, well subjected to the therapy. The disease is manifested in the early age, but its clinical course in children is symptomless that essentially complicates diagnostics. A single reliable method is genetic analysis for revealing mutations in ATP7B gene. The aim of the work was to analyze clinical manifestations and course of Wilson’s disease cases, genetically verified in children by detecting mutations of ATP7B gene. The research group included children of 6-17 years old with different injury degrees of the hepatobiliary system. According to results of the molecular-genetic analysis, the most spread allele variant of ATP7B gene (H1069Q) in Europe was confirmed in 10 patients of child age, including 4 cases of homozygosity. In 10 cases of the confirmed diagnosis of Wilson’s disease in child age in 100% (in all 10) of persons, a clinical manifestation was characterized by disorders from the hepatobiliary system, and only in 1 (10 %) – changes from the nervous system. At raising the level of transaminase in children, even at the normal bilirubin level and negative tests for viral hepatitis, it is recommended to carry out genetic testing for Wilson’s disease

Melioidosis which is caused by burkholderia pseudomallei occurs predominantly in Southeast Asia. Cases are now being reported from india as well. It can present with varying clinical manifestations like pneumonia, septicemia, arthritis, abscess etc. Neurologic meliodiosis, though rare can occur in upto 3-4% cases. Here we present two cases of melioidosis from Indian subcontinent, one involving central nervous system causing cerebral abscess and second one involving multiple splenic and liver abscess with bacteremia. First patient with cerebral abscess was managed with surgical debridement with antibiotics and discharged in a stable condition after 15 days while the bacteremic patient developed septic shock with mutiorgan failure and succumbed to death after 12 days of treatment

The Central Nervous System

One of the complications of the postoperative period in children is postanesthetic agitation, a significant emotional and uncontrollable worry, clouding of consciousness, feeling of anxiety and fear, inappropriate behavior, irritability, inconso­lable crying, aggressive and negative attitude towards parents and medical staff. Postoperative agitation is very important for clinicians and hospitals, it has a risk of harming a patient, staying longer in the ward after anesthesia, and increasing the period of postoperative recovery. The frequency of postoperative agitation depends on age group. Most often agitation occurs in young children. There is evidence that agitation can also be due to the immature nervous system and a consequence of pathological conditions of the central nervous system (asthenoneurotic syndrome, encephalopathy, hyperactivity syndrome, perinatal posthypoxic and organic brain lesions, history of prematurity, epilepsy, psychophysical and speech delay, etc.). That is why the goal of our research was to study the patterns of clinical manifestations of postoperative agitation syndrome in children with prenatal da­mage to the central nervous system. The work was performed based on the analysis of the postoperative period in 109 young children: 59 patients with acquired hydrocephalus, who underwent ventriculoperitoneal shunting, and 50 children without neurological disorders in whom reconstructive surge­ries were carried out. Depending on the type anesthetic management, each group was divided into two subgroups: children, who received inhalation anesthesia with sevoflurane, and those, who received total intravenous anesthesia using propofol. In the postoperative period, the behavior of children was assessed on a Pediatric Ane­sthesia Emergence Delirium scale 30 minutes after anesthesia was completed. Criterion for the development of agitation was the presence of excitement in a child with a score of ≥ 10 points. Study showed that young children with perinatal damage to the central nervous system and children whose anesthetic provision is carried out using sevoflurane are the most vulnerable to the development of agitation syndrome. Agitation in such children is more pronounced and longer. These cases require prediction, detection and active surveillance.
