Prognostic Value of Impaired Preoperative Ankle Reflex in Surgical Outcome of Lumbar Disc Herniation
Background: Several prognostic factors exist influencing the outcome of surgical discectomy in the patients with lumbar disc herniation (LDH). The aim of this study is to evaluate the relationship between severity of preoperative impaired ankle reflex and outcomes of lumbar discectomy in the patients with L5-S1 LDH. Methods: We retrospectively evaluated 181 patients (108 male and 73 female) w...
There are few reports about the effects of perinatal acquired brain lesions on the development of visual perception. These studies demonstrate nonseverely impaired visual-spatial abilities and preserved visual memory. Longitudinal data analyzing the effects of compromised perceptions on long-term visual knowledge in agnosics are limited to lesions having occurred in adulthood. The study of chil...
BACKGROUND Idiopathic intracranial hypertension is a condition typically characterised by headache, normal level of consciousness, papilloedema and raised cerebrospinal fluid pressure. Children often present with visual loss and atypical features of raised pressure, posing a diagnostic and management challenge.

OBJECTIVE To study recent trends in the cumulative incidence of visual impairment in childhood over a 15-year period and to assess progress against WHO goals for prevention. DESIGN, SETTING AND PARTICIPANTS Data from a population-based register of visual impairment in southern England were used to estimate cumulative incidence and trends in visual impairment (VI) and severe visual impairment/...
AIM To evaluate the incidence and severity of the impairment of selected cognitive functions in patients after sudden cardiac arrest (SCA) in comparison to patients after myocardial infarction without SCA and healthy subjects and to analyze the influence of sociodemographic and clinical parameters and the duration of cardiac arrest on the presence and severity of the described disorders. MATE...

RESULTS We screened 1069 children and identified 859 with severe disabilities. The mean ag...
Our aim was to further characterize the clinical concept of mild cognitive impairment (MCI). We examined the status of visual attention-related processing in such patients in relation to healthy older adults and patients with Alzheimer's disease (AD) by measuring performance on a computer-based visual search task. We tested 20 older adult control participants, 13 patients with amnestic mild cog...
