Vanishing bile duct syndrome in non-Hodgkin lymphoma: a case report.

Non-Hodgkin lymphoma (NHL) related vanishing bile duct syndrome (VBDS) is a rare condition that often leads to liver failure and death. A 64-year-old man with history of rheumatic heart disease complicated by steno-aortic insufficiency, mild mitral stenosis, atrial fibrillation, left kidney damage, bilateral glaucoma, left internal jugular vein thrombosis, bronchopneumonia, NHL type B (stage IV) treated with chemo and radiotherapy was admitted to our department for jaundice with predominantly cholestatic component. Liver biopsy allowed a diagnosis of VBDS and patient was treated with ursodesossicolic acid (UDCA) 20 mg/kg/day associated with prednisone 1 mg/kg/day with a transient decrease of bilirubin and cholestasis, but a rapid worsening of general clinical conditions followed by severe acute liver failure (ALF), unresponsive to pharmacological therapy, leads to death our patient.

Evaluation of Compatibility between Beetle-Killed Lodgepole Pine (Pinus Contorta var. Latifolia) Wood with Portland Cement.

The compatibility of wood from mountain pine beetle (Dendroctonus ponderosa) killed lodgepole pine (Pinus contorta var. latifolia) with Portland cement was investigated based on time-since-death as a quantitative estimator, and the presence of blue-stained sapwood, brown rot, or white rot as qualitative indicators. The exothermic behavior of cement hydration, maximum heat rate, time to reach this maximum, and total heat released within a 3.

Surround modulation of neuronal responses in V1 is as stable over time as responses to direct stimulation of receptive fields.

In the primary visual cortex (V1) the modulation of neuronal responses by surround stimuli displays considerable variability. At present, it is not known whether this variability across neurons is due to temporal instability or to neuron-specific differences. We explored this question in the cat visual cortex by making multi-channel recordings while repeatedly presenting surround gratings of collinear and orthogonal orientation to the centre stimulus for a period of 96 h.

Prothrombin complex concentrate such as therapy and prophylaxis in factor X-deficient patient (Friuli variant).

Background: Factor X (FX) deficiency is a serious, rare bleeding disorder, with 1 in 500 000 affected people. Hemorrhages, hematuria, epistaxis, and other bleeding complications are frequent.

Case Report: Now, we report a case of a well-known 77-year-old FX-deficient patient (Friuli variant, level <1%, mutation Pro(343)→Ser, exon VIII) with hypertension, chronic obstructive pulmonary disease (COPD), and chronic gastritis, admitted many times to hospital due to surgical complications after aortic abdominal aneurysm (AAA) repair.

Use of recombinant activated factor VII in severe post-partum haemorrhage: data from the Italian Registry: a multicentric observational retrospective study.

Purpose: To report the Italian real experience in clinical practice about recombinant factor VII activated (rFVIIa) in Post-Partum Haemorrhage (PPH) treatment.

Methods: An Italian retrospective survey of severe primary PPH cases treated with rFVIIa was performed. Anamnestic, clinical and haemostatic data about thirty-five patients with PPH, from 2005 to 2007, were collected.

Retinal vein occlusion: evaluation of "classic" and "emerging" risk factors and treatment.

Retinal vein occlusion (RVO) is the second most common retinal vein disease and an important cause of blindness and visual morbidity. Systemic risk factors are commonly associated with RVO, while unclear it is the role of the thrombophilic and coagulation disorders. To evaluate "classic" and "emerging" risk factors, and to establish a good treatment for RVO.

Practical use of intermittent pneumatic compression as thromboprophylaxis in neurosurgery.

Most patients undergoing neurosurgery are considered at increased risk for venous thromboembolism (VTE). Several studies have demonstrate that intracranial surgery, malignancy, leg weakness, prolonged procedures and advanced age can to increase VTE. Use of thromboprophylaxis is recommended to avoid this risk.

PBMCs protein expression profile in relapsing IFN-treated multiple sclerosis: A pilot study on relation to clinical findings and brain atrophy.

This cross-sectional study investigated with two-dimensional gel electrophoresis coupled to MALDI-TOF and MRI the relationship between PBMCs protein expression profile and whole-brain atrophy in 16 unselected RR-MS IFN-treated patients compared with 6 RR IFN-untreated and 12 matched healthy control subjects. Grey/white matter fraction, T1/T2 lesion load and clinical variables were considered too. Twenty six proteins showed significant differential expression among RR IFN-treated patients and control samples.

Coagulation and oxidative stress plasmatic levels in a type 2 diabetes population.

Type 2 diabetes mellitus (DM2) is a metabolic disorder characterized by relative insulin deficiency, insulin resistance and hyperglycemia. DM2 improperly managed can cause severe complications such as renal failure, blindness or arterial disease. In addition to serious complications due to DM2, in the past 20 years, several studies have demonstrated the association between DM2, insulin resistance and prothrombotic risk.

One carbon metabolism disturbances and the C677T MTHFR gene polymorphism in children with autism spectrum disorders.

Autism spectrum disorders (ASDs), which include the prototypic autistic disorder (AD), Asperger's syndrome (AS) and pervasive developmental disorders not otherwise specified (PDD-NOS), are complex neurodevelopmental conditions of unknown aetiology. The current study investigated the metabolites in the methionine cycle, the transsulphuration pathway, folate, vitamin B(12) and the C677T polymorphism of the MTHFR gene in three groups of children diagnosed with AD (n= 15), AS (n= 5) and PDD-NOS (n= 19) and their age- and sex-matched controls (n= 25). No metabolic disturbances were seen in the AS patients, while in the AD and PDD-NOS groups, lower plasma levels of methionine (P= 0.

Paraoxonase 1 activities and polymorphisms in autism spectrum disorders.

Autism spectrum disorders (ASD) comprise a complex and heterogeneous group of conditions of unknown aetiology, characterized by significant disturbances in social, communicative and behavioural functioning. Recent studies suggested a possible implication of the high-density lipoprotein associated esterase/lactonase paraoxonase 1 (PON1) in ASD. In the present study, we aimed at investigating the PON1 status in a group of 50 children with ASD as compared to healthy age and sex matched control participants.

Behavioral effects of corpus callosum transection and environmental enrichment in adult rats.

A common assumption about the corpus callosum transection (CCX) is that it only affects behaviors heavily relying on interhemispheric communication. However, cerebral laterality is ubiquitous across motor and perceptual, cognitive and emotional domains, and the corpus callosum is important for its establishment. Several recent studies showed that the partial denervation of the sensorimotor isocortex through CCX derepressed neural growth processes that were sensitive to motor demand (experience-dependent neural plasticity).

High levels of homocysteine and low serum paraoxonase 1 arylesterase activity in children with autism.

Autism is a behaviorally defined disorder of unknown etiology that is thought to be influenced by genetic and environmental factors. High levels of homocysteine and oxidative stress are generally associated with neuropsychiatric disorders. The purpose of this study was to compare the level of homocysteine and other biomarkers in children with autism to corresponding values in age-matched healthy children.

Neuroelectric procedure does not discriminate between painful and paresthetic diabetic neuropathy.

To investigate whether pain and paresthesias could identify two different subclasses of small-fibre diabetic neuropathy, and to evaluate their relation to the metabolic control, we tested nerve conduction velocity (NCV) of median nerve (sensitive-SM, and motor-MM) and deep peroneal nerve (DP) in 48 diabetics (24 IDDM, 24 NIDDM) reporting pain (group A) or paresthesias (group B) that might be due to diabetic polyneuropathy. Glycated haemoglobin (HbA1c) was also assessed. No difference between group A and group B was found either in NCV, in all nerves tested, or in HbA1c.

Trigemino-cervical reflex in pathology of the brain stem and of the first cervical cord segments.

The trigemino-cervical reflex (CR) sensitivity and specificity in the assessment of cervico-bulbar lesions was evaluated in eleven selected subjects (4 multiple sclerosis, 3 tumoural processes and 4 cervical cord spondilogenetic myelopathies). Results were compared with those obtained from others neurophysiological investigations (EMG and blink-reflex) and with neuroimaging findings. Significant abnormal responses of CR were found in all patients varying from absent responses, to delayed or reduced amplitude patterns.
