Current treatments include the use of endovascular carotid stenting, which carries with it a high risk of propagating further embolic events and worsening the dissection. New strategies for avoiding the aforementioned side-effects include recanalization using cross-collaterals for delivery of intra-lesional tissue plasminogen activator(t PA). We present two cases that provide further support for this novel approach. Both patients presented with a National Institute of Health Stroke Scale of 20, received intra-arterial t PA via cross-collateralization, and made full recoveries without the need for stenting.展开更多

This study aimed to investigate the impact of postoperative intravenous fluid administration on intensive care unit(ICU), in this subgroup of patients. Methods: A single-center retrospective cohort of 241 HPB patients was assessed, focusing on intravenous fluid administration in ICU, during the first 24 h. Intravenous fluid variables were compared to hospital stay and postoperative complications. Data were assessed using Spearman's correlation test for bivariate correlations and logistic regression for multivariate analysis. Results: The median volume of intravenous fluid administered in the first 24 h postoperatively was 4380 mL, of which 2200 mL was crystalloid, 1500 mL colloid and 680 mL "other" fluid. Patients with one or more complications had a higher median total intravenous fluid input(4790 vs. 4300 mL), higher colloid volume(20 0 0 vs. 150 0 mL), lower urine output(1595 vs. 1900 mL) and greater overall fluid balance( + 3040 vs. + 2553 mL) than those without complications. There were correlations between total intravenous fluid volume administered( r = 0.278, P < 0.001), intravenous colloid input( r = 0.278, P < 0.001), urine output( r =-0.295, P < 0.001), positive fluid balance( r = 0.344, P < 0.001) and length of hospital stay. Logistic regression model was constructed to predict the occurrence of one or more complications; total intravenous fluid volume and overall fluid balance were both independent significant predictors(OR = 2.463, P = 0.007; OR = 1.001, P = 0.011; respectively). Conclusions: Administration of high volumes of intravenous fluids in the first 24 hours post-HPB surgery, along with higher positive fluid balance is associated with a higher rate of complications and longer hospital stay. Moreover, lower urine output is associated with longer hospital stay. Whether these are the cause of complications or the result of them remains unclear.展开更多

Typically, the hindbrain structures, esp ecially the cerebellum, are most affected. There is a surprising lack of studies investigating in detail the behavioural functioning of patients with such a con dition. In this study, we document for the first time the cognitive, social and emotional processing of six patients with a confirmed clinical diagnosis of supe rficial siderosis. They were aged between 40 and 62 years, with a mean age of 50 .2 years; four were male. We administered a comprehensive battery of general cog nitive ability and social cognitive tasks. A review of MRI was also undertaken. The findings indicate selective cognitive impairments affecting speech productio n, visual recall memory and executive functions. In addition, a selective patter n of social dysfunction, affecting the ability to represent other people’s ment al states, was found. These behavioural dysfunctions are reported in the context of MRI-documented lesions maximally involving the cerebellum, in particular th e superior vermis, as well as the medial and inferior frontal cortex. These resu lts suggest that superficial siderosis is associated with a distinct pattern of cognitive and social impairments. They are consistent with the recently proposed role of the cerebellum as a modulator of cognitive, social and emotional functi ons.展开更多

Transanal irrigation has proven to be a treatment for many such individuals, but there are some patients with sub-optimal response to it. Our aim was to evaluate the satisfaction, safety, perception and compliance of a new transanal irrigation device, Navina Smart system featuring an electronically driven pump with a digital control. Material and methods： Twenty-eight patients who had previously used, or were currently using transanal irrigation were enrolled. They were trained to use the Navina Smart system and were thereafter treated for four weeks. Patient perception, compliance and level of satisfaction were assessed at baseline and at the end of treatment. Results： At the end of treatment 68% of patients were still using the system and 50% of ITT （intended to treat） wished to continue using the system. Navina Smart was well tolerated with no adverse effects in the cohort. Patient perception of the Navina Smart system was positive in 67%. Conclusions： Navina Smart system was shown to be safe, tolerable and effective in two-thirds of patients who were unsatisfied with their previous bowel care and was associated with an increase in the patient＇s independence.展开更多

In this report we describe the occurrence of SUNCT in a family. Unfortunately, one of the siblings was already dead.
