Plasma HIV-1 RNA and route of transmission in oral candidiasis and oral hairy leukoplakia

2000

Basal opioid receptor binding is associated with differences in sensory perception in healthy human subjects: a [18F]diprenorphine PET study.

2009

The endogenous opioid system is involved in many body functions including pain processing and analgesia. To determine the role of basal opioid receptor availability in the brain in pain perception, twenty-three healthy subjects underwent positron emission tomography (PET) utilizing the subtype-nonselective opioid antagonist [(18)F]diprenorphine, quantitative sensory testing (QST) and the cold pressor test. Binding potentials (BPs) were calculated using a non-invasive reference tissue model and statistical parametric mapping was applied for t-statistical analysis on a voxelwise basis. We found that cold pain-sensitive subjects present a significantly lower BP in regions including the bilater…

Deep Venous Thrombosis: Leukocyte Rheology at Baseline and after in vitro Activation

2001

We evaluated leukocyte rheology, expressed as leukocyte filtration, polymorphonuclear (PMN) membrane fluidity and cytosolic Ca<sup>2+</sup> concentration in subjects with acute deep venous leg thrombosis (DVT). In 14 subjects with leg DVT we examined the leukocyte filtration [unfractionated, mononuclear cells (MN), PMNs], PMN membrane fluidity and PMN cytosolic Ca<sup>2+</sup> concentration. Subsequently, we evaluated the same PMN variables after in vitro chemotactic activation with 4-phorbol-12-myristate-13-acetate. At baseline, we observed a significant difference in the filtration of unfractionated and MNs and in PMN cytosolic Ca<sup>2+</sup> concentra…

Endovascular treatment of CCSVI in patients with multiple sclerosis: clinical outcome of 462 cases

2013

Although it is still debated whether chronic cerebro-spinal venous insufficiency (CCSVI) plays a role in multiple sclerosis (MS) development, many patients underwent endovascular treatment (ET) of CCSVI. The objective of the study is to evaluate the outcome and safety of ET in Italian MS patients. Italian MS centers that are part of the Italian MS Study Group were all invited to participate to this retrospective study. A structured questionnaire was used to collect detailed clinical data before and after the ET. Data from 462 patients were collected in 33 centers. ET consisted of balloon dilatation (93 % of cases) or stent application. The mean follow-up duration after ET was 31 weeks. Mean…

Pharmacokinetics, pharmacodynamics, and safety of moss-aGalactosidase A in patients with Fabry disease.

2019

Moss-aGalactosidase A (moss-aGal) is a moss-derived version of human α-galactosidase developed for enzyme replacement therapy in patients with Fabry disease. It exhibits a homogenous N-glycosylation profile with >90% mannose-terminated glycans. In contrast to mammalian cell produced α-galactosidase, moss-aGal does not rely on mannose-6-phosphate receptor mediated endocytosis but targets the mannose receptor for tissue uptake. We conducted a phase 1 clinical trial with moss-aGal in six patients with confirmed diagnosis of Fabry disease during a 28-day schedule. All patients received a single dose of 0.2 mg/kg moss-aGal by i.v.-infusion. Primary endpoints of the trial were safety and pharmaco…

Intraoperative monitoring of cerebral microcirculation and oxygenation--a feasibility study using a novel photo-spectrometric laser-Doppler flowmetry.

2009

The present study assesses the utility of a novel invasive device (O2C-, oxygen-to-see-device) for intraoperative measurement of the cerebral microcirculation. CO2 vasoreactivity during 2 different propofol concentrations was used to investigate changes of capillary venous cerebral blood flow (rvCBF), oxygen saturation (srvO2), and hemoglobin concentration (rvHb) during craniotomy.Thirty-four patients were randomly assigned to a low propofol (4 mg/kg/h) versus a high propofol (6 mg/kg/h) group. A fiberoptic probe was applied on the cortex next to the surgical site. Measurements were performed during lower (35 mm Hg) and higher (45 mm Hg) levels of partial pressure of carbon dioxide (paCO2).…

Ultrasound-guided port-a-cath positioning with the new one-shoot technique: thoracic complications.

2018

Port-a-cath catheterization is often required for those patients who need long-term therapies (malnutrition, neoplasm, renal failure, other severe diseases). The use of ports for a wide range of indications is not exempt from complications. Ultrasound-guided central venous catheterization (CVC) is a safe and fast technique for the introduction of the catheter inside a central vein. This retrospective study reports our experience with US-guided CVC in patient eligible for port-a-cath implantation.From January 2007 to March 2017, 108 CVC (out of 770 procedures), were positioned using an ultrasound guide, with the new "one-shoot technique" (group 1) and the classic Seldinger technique (group 2…

Adjuvant Fluorouracil, Leucovorin, and Oxaliplatin in Stage II to III Colon Cancer: Updated 10-Year Survival and Outcomes According to BRAF Mutation …

2015

Purpose The MOSAIC (Multicenter International Study of Oxaliplatin/Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer) study has demonstrated 3-year disease-free survival (DFS) and 6-year overall survival (OS) benefit of adjuvant oxaliplatin in stage II to III resected colon cancer. This update presents 10-year OS and OS and DFS by mismatch repair (MMR) status and BRAF mutation. Methods Survival actualization after 10-year follow-up was performed in 2,246 patients with resected stage II to III colon cancer. We assessed MMR status and BRAF mutation in 1,008 formalin-fixed paraffin-embedded specimens. Results After a median follow-up of 9.5 years, 10-year OS rates in the bolus/…

Reliability and validity of the Newcastle Scales in relation to ICD-9-classification

1987

The assessment of endogenous depression by means of the Newcastle Scales (1965, 1971) has been validated by their correlation with biological findings in many previous studies. However, reliability and cross validation studies are lacking for these scales. We found the reliability of the Newcastle Scales to be sufficient or at least moderate in a sample of 70 inpatients with major depression. In order to cross validate both scales, the clinical classification according to ICD-9 and the assessment of the Newcastle Scales have been performed independently in a sample of 112 inpatients with Major Depressive Disorder (RDC). The rate of agreement between clinical diagnosis and classification acc…
