Idiopathic normal pressure hydrocephalus (NPH) remains both over-suspected on clinical grounds and under-confirmed when based on immediate and sustained response to cerebrospinal fluid diversion. Poor long-term post-shunt benefits and findings of neurodegenerative pathology in most patients with adequate follow up suggests that hydrocephalic disorders appearing in late adulthood may often result from initially unapparent parenchymal abnormalities. We critically review the NPH literature, highlighting the near universal lack of blinding and controls, the absence of specific clinical, imaging, or pathologic features, and the ongoing dependence for diagnostic confirmation on variable cutoffs of gait response to bedside fluid-drainage testing...

BACKGROUND: We sought to investigate the adverse effects of perinatal exposure to nonylphenol (NP) on carbohydrate metabolism of male offspring rats. METHODS: Thirty-two healthy pregnant Sprague Dawley rats were randomly divided into four groups, control normal diet group (C), NP normal diet group (NPN), control high-energy diet group (CH), and NP high-energy diet group (NPH). Both of the control groups were received a gavage of corn oil and the NP-groups were received NP (200 mg/kg/day) from gestational days 6 to post-natal day (PND) 21...

It may be challenging to differentiate normal pressure hydrocephalus (NPH) from neurodegenerative disorders such as Parkinson's disease. In this population-based study, we wanted to describe the frequency of parkinsonian symptoms among individuals with and without NPH, and whether the motor examination part of the Unified Parkinson's Disease Rating Scale (UPDRS-m) score differs between these groups. Furthermore, we wanted to find out whether there was a relationship between UPDRS-m score, NPH symptoms, and radiological signs of NPH...

BACKGROUND: Aqueductal stroke volume (ACSV) measured by phase-contrast cine (PCC)-MRI has been proposed with controversy as a tool for the selection of patients with normal pressure hydrocephalus (NPH) as candidates for shunt-surgery. The aim of this study was to assess if PCC-MRI scan measurements of ACSV could select properly these patients. METHODS: We retrospectively reviewed charts and MRI of 38 shunted patients (72,16 ±6,16 years). ACSV measurements were performed 7-30 days before shunt and at the first and sixth months after surgery...

OBJECTIVE: Cortical cerebral amyloid disease, a hallmark of Alzheimer's disease, has also been observed in idiopathic normal pressure hydrocephalus (iNPH). The aim of this study was to compare the (11)C-PIB PET/CT retention pattern in iNPH patients and healthy subjects. MATERIAL AND METHODS: A comparison was made of the (11)C-PIB PET/CT retention pattern in 13 iNPH patients selected for surgical deviation, compared to a normal control population. Images were visually analyzed and scored for gray matter and white matter (WM) from 1 to 4 (slight to very high PIB retention)...

Gestational diabetes mellitus (GDM) is associated with an increased risk of adverse pregnancy outcomes in the setting of poor glycemic control. The initial management for GDM includes intensive lifestyle modification, which often requires behavioral and nutritional changes to optimize glycemic control. Pharmacotherapy for GDM is initiated when glycemic targets are not met. The rapid-acting bolus analogues aspart and lispro achieve postprandial targets with less hypoglycemia compared to regular insulin, with similar fetal outcomes...

Differential diagnosis between vascular parkinsonism (VP) and idiopathic normal pressure hydrocephalus (iNPH) is particularly challenging due to similar clinical and neuroradiological features. The objective of this study is to differentiate VP with radiological evidence of ventricular enlargement (REVE) from iNPH on the basis of cerebrospinal fluid (CSF) hydrodynamics. CSF pressure components were investigated in patients with a clinical diagnosis of VP and REVE. Data of eight patients (seven men; age 76 ± 3...

BACKGROUND: The pathogenesis of normal pressure hydrocephalus (NPH) remains unclear which limits both early diagnosis and prognostication. The responsiveness to intervention of differing, complex and concurrent injury patterns on imaging have not been well-characterized. We used diffusion tensor imaging (DTI) to explore the topography and reversibility of white matter injury in NPH pre- and early after shunting. METHODS: Twenty-five participants (sixteen NPH patients and nine healthy controls) underwent DTI, pre-operatively and at two weeks post-intervention in patients...

INTRODUCTION: Type 2 diabetes mellitus (T2DM) has attained epidemic proportions and continues to increase despite the availability of a number of oral antidiabetic medications and major advances made in insulin delivery since its discovery nearly a hundred years ago. One, amongst many other reasons responsible for the inability to achieve adequate glycaemic control in a substantial proportion of T2DM patients is the delayed initiation and inappropriate intensification of insulin treatment...

The synthesis of bis(N1-phenyl-5-hydroxypyrazol-3-yl)pyridines ("L") is described, and these are silylated to achieve analogues ("Si2L") without the variable of the hydroxyl proton mobility. One hydroxyl example is characterized in its bis-pincer iron(II) complex, which shows every OH proton involved in hydrogen bonding. The steric bulk of the silylated N-phenyl-substituted ligands allows the synthesis and characterization of paramagnetic (Si2L)FeCl2 complexes, and one of these is reduced, under CO, to give the diamagnetic (Si2L)Fe(CO)2 species...

Reasonable glycemic control is difficult to achieve in patients with diabetes mellitus (DM) receiving continuous enteral nutrition therapy (CENT). There are no solid evidence-based medicine guidelines regarding this issue in these patients. The purpose of this study was to determine if the use of a basal-bolus insulin regimen is more effective than neutral protamine Hagedorn (NPH) insulin alone in controlling blood glucose in non-critically ill patients with DM receiving CENT. We performed a retrospective, records-based review comparing basal-bolus with NPH insulin regimen in these patients, hospitalized in the internal medicine wards in our hospital...

Subacute ruminal acidosis (SARA) is usually characterized by abnormal and intermittent drops in rumen pH. Nevertheless, high individual animal variability in rumen pH and the difference in measurement methods for pH data acquisition decrease the sensitivity and accuracy of pH indicators for detecting SARA in ruminants. The aim of this study was to refine rumen pH indicators in long-term SARA based on individual dairy cow reticulo-rumen pH kinetics. Animal performances and rumen parameters were studied weekly in order to validate SARA syndrome and rumen pH was continuously measured using reticulo-rumen sensors...

CLINICAL CASE: The case is presented of a 73-year-old male patient who referred to having black and white vision. Computed tomography showed normal pressure hydrocephalus (NPH). Magnetic resonance imaging was not performed because the patient refused to undergo further examinations. DISCUSSION: Achromatopsia may be the first or only NPH symptom. It may be prudent to ask patients with NPH regarding colour vision.

BACKGROUND: Literature on cognition in normal pressure hydrocephalus (NPH) is sparse and more so on cognition in advanced NPH. OBJECTIVE: To study the cognitive profile in a hospital-based cohort of cognitively-advanced NPH. SETTINGS AND DESIGN: This was a prospective cross-sectional study. The patients included those availing dementia care service from three different tertiary care centres during a period of 5 years from 2010 to 2014. Patients were considered to have cognitively-advanced NPH if the Addenbrooke's Cognitive Examination(ACE) score was 50 or less...
