Patients' and relatives' perceptions about intravenous and subcutaneous hydration.
2005
Hydration during palliative care is a controversial topic. Most of the arguments are based on anedoctal reports that have not been substantiated with scientific data. Given that the choice is problematic from a clinical perspective, preferences of patients and family should dictate whether intravenous fluids are administered. The aim of this study was to evaluate patient and family perceptions about hydration and two modes of providing hydration. Fifty-four consecutive patients admitted to an acute pain relief and palliative care unit who required hydration completed a questionnaire regarding their perceptions on hydration and modes of hydration. Similarly, the principal family carer was ch…
A prospective evaluation of the activity of human granulocyte-colony stimulating factor on the prevention of chemotherapy-related neutropenia in pati…
1993
After informed consent, 86 patients with advanced cancer undergoing potentially myelosuppressive cytotoxic chemotherapy were randomized to receive placebo or subcutaneous granulocyte - colony stimulating factor (G- CSF) 5 μg/Kg/day in order to prevent severe neutropenia and its related morbidity. The incidence of neutropenia (absolute neutrophil count <1, 000/mm3) was significantly reduced in patients receiving G-CSF than in controls (18% versus 42%; P <0.05). The duration of neutropenia was also shortened by the administration of G-CSF (4.8 versus 8.2 days; P <0.05). Therapy with G-CSF has also a positive impact on the dose-intensity of employed regimens. Patients treated with G-CSF showed…
Lower eyelid reconstruction by multiple subcutaneous pedicle flaps: a new method.
1992
Abstract In this paper we present an original technique for the reconstruction of the full thickness of the lower eyelid after excision of neoplasms. The method is based on the mobilisation of multiple pedicle subcutaneous flaps outlined in the same eyelid and supported by a chondro-mucosal graft. This technique is used for central and off-central losses which involve the outer rim or up to 75% of the width of the whole eyelid. This method is an alternative to the Hughes (1945), Mustarde´(1981), Tenzel and Stewart (1978) and McGregor (1973) techniques which we have previously used for this type of reconstructive The follow-up is satisfactory in terms of the oncological, functional and aesth…
Interleukin 12 induces activation of fibrinolysis and coagulation in humans
2001
Interleukin 12 (IL-12) has potential efficacy in malignant, infectious and allergic diseases. Its side-effects include activation of coagulation and fibrinolysis, as documented in chimpanzees. We assessed the coagulative and fibrinolytic response in 18 patients with renal cell carcinoma after subcutaneous injection of 0.5 microg/kg recombinant human IL-12. IL-12 induced a fibrinolytic response in 17 patients (94%): plasmin-alpha2-anti-plasmin complexes (PAPc) increased from 11.8 +/- 6.6 nmol/l (mean +/- SD) to a maximum of 18.8 +/- 7.4 nmol/l at 72 h. Baseline levels of tissue plasminogen activator (tPA) and plasminogen-activator inhibitor-I (PAI) were elevated in eight and 14 patients resp…
MRI activity and neutralising antibody as predictors of response to interferon beta treatment in multiple sclerosis
2008
Objective: To prospectively validate MRI activity and neutralising anti-interferon antibody (NAb) during the first 6 months of interferon β treatment as response indicators in multiple sclerosis (MS). Methods: Patients with relapsing–remitting MS were followed during the first 2 years of treatment. Neurological assessments were performed every 3 months or when a relapse was suspected. MRI scans performed at baseline and at 3, 4, 5 and 6 months after the start of treatment were assessed centrally for disease activity: new T2 or gadolinium enhancing T1 lesions. NAb were assessed using the MxA protein assay; positivity was defined as two consecutive titres ⩾20 NU/ml. We evaluated the predictiv…
Subcutaneous interferon β-1a may protect against cognitive impairment in patients with relapsing-remitting multiple sclerosis: 5-year follow-up of th…
2013
ObjectiveTo assess the effects of subcutaneous (sc) interferon (IFN) -1a on cognition over 5 years in mildly disabled patients with relapsing-remitting multiple sclerosis (RRMS).MethodsPatients aged 18-50 years with RRMS (Expanded Disability Status Scale score ≤4.0) who had completed the 3-year COGIMUS study underwent standardized magnetic resonance imaging, neurological examination, and neuropsychological testing at years 4 and 5. Predictors of cognitive impairment at year 5 were identified using multivariate analysis.ResultsOf 331 patients who completed the 3-year COGIMUS study, 265 participated in the 2-year extension study, 201 of whom (75.8%; sc IFN β-1a three times weekly: 44 µg, n = …
Ex Vivo Tracking of Endogenous CO with a Ruthenium(II) Complex.
2017
[EN] A two-photon fluorescent probe based on a ruthenium(II) vinyl complex is capable of selectively detecting carbon monoxide in cells and ex vivo using mice with a subcutaneous air pouch as a model for inflammation. This probe combines highly selective and sensitive ex vivo detection of endogenous CO in a realistic model with facile, inexpensive synthesis, and displays many advantages over the widely used palladium-based systems.
High-Temperature Sintering of Xenogeneic Bone Substitutes Leads to Increased Multinucleated Giant Cell Formation: In Vivo and Preliminary Clinical Re…
2014
The present preclinical and clinical study assessed the inflammatory response to a high-temperature–treated xenogeneic material (Bego-Oss) and the effects of this material on the occurrence of multinucleated giant cells, implantation bed vascularization, and regenerative potential. After evaluation of the material characteristics via scanning electron microscopy, subcutaneous implantation in CD-1 mice was used to assess the inflammatory response to the material for up to 60 days. The clinical aspects of this study involved the use of human bone specimens 6 months after sinus augmentation. Established histologic and histomorphometric analysis methods were applied. After implantation, the mat…
Testosterone administration increases leukocyte-endothelium interactions and inflammation in transgender men

The complex alteration in the network of IL-17-type cytokines in patients with hereditary angioedema
2018
Hereditary angioedema (HAE) is a rare autosomic-dominant disorder characterized by a deficiency of C1 esterase inhibitor which causes episodic swellings of subcutaneous tissues, bowel walls and upper airways that are disabling and potentially life-threatening. We evaluated n = 17 patients with confirmed HAE diagnosis during attack and remission state and n = 19 healthy subjects. The samples were tested for a panel of IL (Interleukin)-17-type cytokines (IL-1β, IL-6, IL-10, granulocyte–macrophage colony stimulating factor (GM-CSF), IL-17, IL-21, IL-22, IL-23) and transforming growth factor-beta (TGF-β) subtypes. Data indicate that there are variations of cytokine levels in HAE subjects compar…
