Abstract
Introduction Several studies have shown that the working memory is sensitive to temporal variations. We used a new visuospatial working memory task, the "Time Squares Sequences," to investigate whether implicit variations in stimuli presentation time affect task performance. Methods A total of 50 healthy participants saw two sequences (S1 and S2) of seven white squares presented in a matrix of gray squares and assessed whether S2 matched S1. There were four conditions depending on the spatial position and the presentation time (i.e., timing) of the white squares in S1 and S2: two with the same (S1 fixed/S2 fixed and S1 variable/S2 variable) and two with different (S1 fixed/S2 variable and S1 variable/S2 fixed) presentation times. Results Findings showed impaired performance when S1 had a fixed presentation time and S2 had a variable presentation time. Conclusion These findings are attributed to increased cognitive load due to S2 timing difference, pointing to a monitoring process, sensitive to temporal variations.

Abstract
Our aim is to investigate, through a broad review of medical literature, the role of depressive syndrome on the adherence to lifestyle modifications (TLC) in patients with risk factors for cardiovascular disease (CVD). We conducted a systematic computerized literature search of MEDLINE using the following key words: depressive syndrome, cardiovascular risk factors, lifestyle, physical activity, diet, smoking, blood pressure, metabolic syndrome and diabetes. We have considered metanalyses studies, reviews, original articles, case-control studies published between 1992 and 2010. Furthermore, we have considered the impact of depressive syndrome on the different cardiovascular risk factors. From our search we have selected 42 English articles published between 1992 and 2010 of whose 16 were longitudinal cohort studies, 5 research reports, 10 longitudinal case-control studies, 2 metanalyses, 5 reviews and 4 prevalence studies. All our selected studies agree to give to depressive syndrome a negative role on the adherence to lifestyle modifications. For this reason, depression represents an indirect and independent cardiovascular risk factor that needs to be detected and treated for a successful cardiovascular prevention.

Abstract
INTRODUCTION Diabetes mellitus (DM) can be complicated by an involvement of Neurovegetative System (NVS), conventionally and non-invasively diagnosed by the means of Ewing's test and Heart Rate Variability (HRV) analysis. It is well known that the NVS is physiologically responsible, via biological clocks, for the regulation of Circadian Rhythms (CR) characterizing the majority of biological functions. Therefore, this study is aimed at investigating the CR of Heart Rate (HR) and Blood Pressure (BP) in DM, postulating that the diagnosis of Silent Cardiac Dysautonomia (SCD) could be facilitated by detecting anomalous rhythmometric changes, including the worse one, i.e., the lose of a CR. MATERIALS AND METHODS The study has been performed on 30 clinically healthy subjects (CHS), 10 patients with DM1 and 30 patients with DM2, who underwent an ambulatory BP monitoring (ABPM) collecting data equidistantly every 30 minutes, under standardized conditions of lifestyle. The group specific monitored values of systolic (S), diastolic (D) BP, as well as HR have been analyzed via: 1. a conventional analysis of their intradiem variability; 2. a chronobiometric analysis (Cosinor method) of their CR. RESULTS The conventional analysis disclosed that in CHS, DM1 and DM2, both the HR and BP show an intradiem variability that is significant (p less than 0.001). The chronobiological analysis showed that in CHS and DM2, both the HR and BP show a significant CR (p less than 0.001), viceversa in DM1 HR is characterized by a non significant CR (p=0.124), notwithstanding that the SBP and DBP maintain a significant CR (p less than 0.001). CONCLUSIONS The disappearance of HR CR in DM1 reveals the involvement of neurovegetative biological clock that selectively controls the HR CR, as it is demonstrated by the pathophysiological finding of an internal desynchronization between the HR and BP CR. The selective lose of HR CR in DM1 leads to conclude that the ABPM, along with its Cosinor analysis, might be a practical, repeatable, low cost, low risk technique for diagnosing the SCD, at least in DM1.

Abstract
18 cases of benign intradural spinal cyst (9 arachnoidal, 2 neuroepithelial, 7 endodermal) are reported and compared with 94 cases (67 arachnoidal, 7 neuroepithelial, 20 endodermal) obtained from the literature. Arachnoidal intradural cysts (AIC) have no sex preference, occur at around the fourth-fifth decades of life and have characteristic intermittent root symptoms. They prefer the thoracic level and the posterior position. (Myelography images the cystic cavity (diverticular form). Surgical removal is usually easy. Neuroepithelial intradural cysts (NIC) are rare, have a 2:1 predilection for females and occur after the fourth decade. They have a serious clinical course similar to intramedullary or extramedullary tumours. They prefer the conus-cauda and the anterolateral positions. They often give rise to manometric block and to albuminocytological dissociation. There may be substantial adhesions to the cord and roots and the intramedullary variety presents no clear plane of cleavage. Endodermal intradural cysts (EIC) have a 2:1 predilection for males and prefer the second and third decades. They may have an intermittent or serious course with signs of root and cord impairment. They prefer the cervical segment (in the anterior position) and the conus-cauda (in the posterior position). As a rule they present manometric block and albuminocytological dissociation. Their frequent tough adhesions to the roots and cord demand special care during their removal.

Abstract
The authors report on the results obtained on a series of 325 patients operated on for single brain metastasis at the Institute of Neurosurgery of the University of Rome during the period 1951-1979. After analyzing the results vis-à-vis the site of the brain metastasis, the site of the primitive tumour and the surgical treatment administered; emphasis is given to the importance of the advent of the CT scan which has permitted a more accurate selection of the patients resulting in improvement in operative mortality and average survival time which at present is one year.

Abstract
24 cases of cystic cerebral astrocytoma represent 11% of 217 supratentorial tumors of the pediatric age group operated. Both macro- and microscopically, such tumors resembled in most cases the well-known cerebellar astrocytoma, presenting as a large cyst with a mural nodule with the pattern of a pilocytic astrocytoma (i.e. spongioblastoma of the German school). The preferential site of incidence was the temporal lobe and the age peaks were of 7 and 16 years without sex prevalence. The surgical technique consisted in the extirpation of the mural nodule, preceded by emptying the cyst, followed by opening the contiguous ventricular wall. The extirpation was partial in one-third of the cases of whom the minority underwent radiotherapy. 1 patient died after the operation while 2 others died from tumor recurrence after 3 and 4 years, respectively, both being mixed tumors (oligoastrocytoma) that were irradiated postoperatively. The follow-up ranged from 10 to 29 years in 70% of the cases. The long-term functional results of the available 17 patients are as follows: good (perfectly well), 12 cases (70%); fair (minor troubles), 5 cases (30%). 3 of the 5 cases with a fair result all had a partial resection.

Abstract
In a series of 41 cases of hemispheric supratentorial astrocytoma (HSA) in children, 29 patients have been followed for periods ranging from 5 to 27 years. The follow-up data show that HSA's are relatively benign tumors. Twenty-two patients (76%) are still living: 12 in good, eight in fair, and two in poor neurological condition. Their mean survival is 13.3 years. Five patients died from tumor recurrence within 4 years of the operation. All five were operated on before the age of 8 years. The best results in terms of mean survival and quality of life were obtained in cases of cystic HSA, especially the pilocytic variety. In children, HSA tends to take the cystic form (often pilocytic), and its relatively benign course points up an analogy between this rare supratentorial tumor and the more common tumor of the cerebellum (the so-called "cerebellar astrocytoma").

Abstract
The authors report a new case of Joubert syndrome (agenesis of the cerebellar vermis, mental retardation, disturbance of respiratory rhythm, ataxia, abnormal eye-movements) and review the relevant literature on the other nine cases reported. The diagnosis in the present case was confirmed by computerized tomography. Early recognition of this syndrome is important in view of the prognosis and for genetic counseling.

Abstract
Three cases of cerebellar vermis agenesis are reported and the relevant literature (19 other cases) is reviewed. Other posterior fossa malformations, such as a mega-cisterna magna, arachnoid cyst and Dandy-Walker syndrome, are discussed both from the pathological and clinical view point. We put forward a hypothesis that agenesis of the cerebellar vermis and Dandy-Walker syndrome could be regarded as two different stages of the same malformation.
