Randomized trial of intravenous immunoglobulins versus prednisolone in Graves' ophthalmopathy.

1996

Abstract Glucocorticoids are usually given for management of Graves' ophthalmopathy (GO), but they may cause side effects. By comparison, intravenous administration of immunoglobulins resulted in clinical improvement and decreased antibody titres in a large number of autoimmune diseases. Therefore, a randomized trial was done, in which 19 patients with active GO were treated with a 20-week course of oral prednisolone (P, starting dose 100 mg/day), and 21 received 1 g immunoglobulin/kg body weight for 2 consecutive days every 3 weeks. The immunoglobulin course was repeated six times. Before and at the end (20 weeks) of immunomodulating therapy, ophthalmological investigation and quantitative…

Ocular Changes in Patients With Mucopolysaccharidosis I Receiving Enzyme Replacement Therapy

2007

Objective To describe the progression of ocular changes in patients with mucopolysaccharidosis I receiving enzyme replacement therapy. Methods Three male and five female patients with mucopolysaccharidosis I were followed up for 4 years while undergoing enzyme replacement therapy with α-L-iduronidase (Aldurazyme). Visual acuity, corneal clouding, intraocular pressure, ophthalmoscopy, and optic disc measurements were performed yearly. Results Vision remained stable in 5 patients and deteriorated by at least 2 Snellen lines in 3 patients. Deterioration in 2 of these patients was related to progressive corneal clouding. Visual acuities improved in 1 patient after bilateral penetrating keratopl…

Weekly Dose-Dense Cisplatin-Epirubicin-Paclitaxel Administration with Granulocyte Colony-Stimulating Factor Support Does Not Substantially Improve Pr…

2004

Purpose: The present study was aimed at defining the antitumor activity of the cisplatin-epirubicin-paclitaxel (PET) weekly administration with granulocyte colony-stimulating factor (G-CSF) support in chemonaive small-cell lung cancer patients with extensive disease (ED-SCLC). Methods: Chemonaive ED-SCLC patients received cisplatin 30 mg/sqm, epirubicin 50 mg/sqm and paclitaxel 120 mg/sqm, weekly, with G-CSF (5 μg/kg from day 3 to 5) support, for a maximum of 12 weeks. Results: Thirty-nine patients were treated, for a total of 354 cycles delivered. Eight complete (21%), and 22 partial responses (56%) were recorded, giving a 77% (95% Cl = 61-89%) objective response rate (ORR). After 14 (rang…

Intravenous injection of bortezomib, melphalan and dexamethasone in refractory and relapsed multiple myeloma

2013

Abstract Background A combination of bortezomib (1.3 mg/m2), melphalan (5 mg/m2), and dexamethasone (40 mg) (BMD), with all three drugs given as a contemporary intravenous administration, was retrospectively evaluated. Patients and methods Fifty previously treated (median 2 previous lines) patients with myeloma (33 relapsed and 17 refractory) were assessed. The first 19 patients were treated with a twice-a-week (days 1, 4, 8, 11, ‘base’ schedule) administration while, in the remaining 31 patients, the three drugs were administered once a week (days 1, 8, 15, 22, ‘weekly’ schedule). Results Side-effects were predictable and manageable, with prominent haematological toxicity, and a better tox…

Pharmacokinetics and bioavailability of benperidol in schizophrenic patients after intravenous and two different kinds of oral application

1994

Pharmacokinetics and bioavailability of benperidol were determined in 13 schizophrenic patients after acute administration of 6 mg benperidol as an intravenous (i.v.) bolus injection, orally as liquid, and orally as tablets using a partially randomized cross-over design. Drug plasma levels were determined by high performance liquid chromatography with electrochemical detection and subjected to model independent pharmacokinetic analyses. After i.v. dosing the geometric means (mean-g) were 3.2 min for the distribution half-life, 5.80 h for the elimination half-life (t1/2 beta), 4.21 l/kg for the distribution volume, 7.50 h for the mean residence time (MRT), and 0.50 l/(h*kg) for the clearance…

Relationship Between Regional Cerebral Blood Flow and Electrocorticographic Activities Under Sevoflurane and Isoflurane Anesthesia

2010

The aims of this study are (1) to assess the effects of volatile anesthetics on regional cerebral blood flow (rCBF) and electrocorticography (ECoG), and (2) to investigate the relationship between rCBF and ECoG influenced by volatile anesthetics. The authors measured rCBF using laser Doppler flowmetry and ECoG simultaneously and continuously from the same cortex during craniotomy, using the specially arranged probe. Patients received intravenous anesthetics with nitrous oxide until craniotomy, and after opening of dura, volatile anesthetic, either isoflurane or sevoflurane, was started and was gradually increased for the measurement. Four of the nine cases (44.4%) of the sevoflurane group s…

Prospective assessment of postoperative pain after craniotomy.

2010

Pain after craniotomy may be underdiagnosed, despite the fact that it can increase postoperative complications for example arterial hypertension and postoperative hemorrhage. This study investigates the incidence and intensity of pain after craniotomy and characterizes the influencing parameters. During a 1-year period 256 patients undergoing elective craniotomy were prospectively included in the study. Intensity of pain was evaluated 1, 4, and 24 hours after extubation using a verbal numerical rating scale (NRS) ranging from 0 (no pain) to 10 (maximal pain). Routine perioperative pain management was not influenced by the investigators. Parameters including patient-related factors, drug adm…

In vivo release of non-neuronal acetylcholine from human skin by dermal microdialysis: Effects of sunlight, UV-A and tactile stimulus

2007

Non-neuronal acetylcholine (ACh) is expressed in epithelial, endothelial and immune cells. For example, the in vivo release of ACh from the human skin pretreated with botulinum toxin has recently been demonstrated. In the present experiments the effects of light (sunlight and solar radiation by a commercial UV-A applier) and of a tactile stimulus on the release of non-neuronal ACh were investigated. Release of ACh from the proximal and distal shin, i.e. anterior tibial region, was measured by dermal microdialysis in 20 min samples over a time period of at least 140 min. Control experiments were performed in a dark room throughout. In some experiments volunteers were exposed to sunshine (80-…

Thoracoscopic sympathectomy at the T2 or T3 level facilitates bradykinin-induced protein extravasation in human forearm skin.

2010

Background.  The endogenous peptide bradykinin (BK) is an inflammatory mediator that induces nociceptor activation and sensitization as well as protein extravasation and vasodilation. Objective.  To test the hypothesis if sympathectomy affects BK-induced inflammation in humans. Methods.  Dermal microdialysis was employed on the volar forearm in 10 patients (21–41 years) with regional hyperhidrosis before and three months after preganglionic endoscopic transthoracic sympathetic clipping (ETSC) at the T2 or T3 level and in 10 healthy volunteers (22–36 years). After 60 minutes perfusion with Ringer's solution microdialysis fibers were perfused with BK 10−7 M and 10−5 M for 30 minutes followed …
