Role of central oxytocin in the inhibition by endotoxin of distension-stimulated gastric acid secretion
2000
The gastric acid hyposecretory state associated with endotoxemia is mediated by a nervous reflex involving the central nervous system. The aim of the present study was to analyse the central effects of different peptides on distension-stimulated gastric acid secretion and the endogenous role of such peptides on the hyposecretory effects of endotoxin. The effect of an intracisternal (i.c.) administration of oxytocin, vasopressin, corticotropin releasing factor (CRF), bombesin, somatostatin and the opioid receptor agonist BW443C or an intravenous (i.v.) injection of a small dose of endotoxin on distension-stimulated gastric acid secretion was studied in the continuously perfused stomach of an…
Intra-articular hyaluronic acid injections for hip osteoarthritis
2018
Although viscosupplementation has been used in the past few years both for knee and hip osteoarthritis (OA), the number of intra-articular injections and the interval between doses still remains an undetermined subject. The aim of this open retrospective study was to evaluate the clinical and functional outcome in patients with mild-moderate hip OA treated with a course of 1, 2 or 3 Hyaluronic Acid (HA) intra-articular injections. Ninety-six patients were included: 19 patients received only one injection, 24 received two injections, and 44 received three injections. Age, sex, VAS for pain and WOMAC score before each intra-articular injection, number of intra-articular injections, reasons fo…
Is Ranibizumab effective in stopping the loss of vision for Choroidal Neovascularization in Pathologic Myopia? A Long Term Follow-up Study
2010
Aim To assess the efficacy and safety of ranibizumab in the treatment of choroidal neovascularisation (CNV) caused by pathologic myopia (PM). Design Prospective, multicentre, interventional case series. Methods 40 eyes of 39 consecutive patients with PM and CNV were treated with ‘on demand’ intravitreal injection of ranibizumab 0.5 mg. Final best corrected visual acuity (BCVA) and its change from baseline were the main outcome measures. Changes in optical coherence tomography (OCT) central retinal thickness (CRT) were a secondary outcome. Results Mean age was 53±13 years and mean refractive error –13.5±6.5 D. Median follow-up was 13.3±2 (range 12–18) months. Fifteen eyes (37.5%) had previou…
Endophthalmitis after intravitreal injections: incidence, presentation, management, and visual outcome
2015
Purpose To report the incidence and characteristics of endophthalmitis after intravitreal injections of anti–vascular endothelial growth factor agents or corticosteroids and to describe the clinical and bacteriologic characteristics, management, and outcome of these eyes with acute endophthalmitis in France. Design Retrospective, nationwide multicenter case series. Methods From January 2, 2008 to June 30, 2013, a total of 316 576 intravitreal injections from 25 French ophthalmic centers were included. For each center, the number of intravitreal injections was determined using billing codes and the injection protocol was recorded. A registry and hospital records were reviewed to identify pat…
Dexamethasone for unresponsive diabetic macular oedema: optical coherence tomography biomarkers
2019
Purpose: To analyse the effects of intravitreal dexamethasone implant (DEX) in patients with diabetic macular oedema (DME) unresponsive to ranibizumab treatment, in relation to the inflammatory optical coherence tomography (OCT) retinal features, subfoveal neuroretinal detachment (SND) and hyperreflective retinal spots (HRS). Methods: Patients with DME poorly responsive to three injections of ranibizumab were treated with DEX. Best-corrected visual acuity (BCVA) and central macula thickness (CMT, measured by Spectralis SD-OCT) were assessed at baseline and at 1, 3, and 6 months. Results: Overall, 44 eyes were included in the study. In the whole group, mean BCVA (baseline 51.5 ± 8.3 letters)…
DEXAMETHASONE INTRAVITREAL IMPLANT VS RANIBIZUMAB IN THE TREATMENT OF MACULAR EDEMA SECONDARY TO BRACHYTHERAPY FOR CHOROIDAL MELANOMA
2017
PURPOSE To evaluate the efficacy of an intravitreal dexamethasone (Dex) implant 0.7 mg compared with intravitreal ranibizumab (Ra) for the treatment of radiation maculopathy with macular edema secondary to plaque brachytherapy in choroidal melanoma. METHODS Eight patients were treated with intravitreal Ra, and eight patients received the Dex intravitreal implant. Visual acuity and foveal thickness were evaluated using spectral domain optical coherence tomography. RESULTS The mean calculated irradiation to the fovea and mean times from brachytherapy to maculopathy development did not differ significantly between groups. In the Ra group, a mean 7.8 ± 3.9 injections were given and the mean fol…
Anesthetic efficacy of ketamine-diazepam, ketamine-xylazine, and ketamine-acepromazine in Caspian Pond turtles (
2017
Objectives: The objective of this study was to assess the efficacy of different anesthetic drug combinations on the Caspian Pond turtles (Mauremys caspica). Subjects and Methods: Three groups of the Caspian Pond turtles (n = 6) were anesthetized with three different drug combinations. Initially, a pilot study was conducted to determine the best drug doses for the anesthetization of the turtles, and according to these results, ketamine–diazepam (120 mg/kg ketamine hydrochloride [5%] and 2 mg/kg diazepam [5%]), ketamine–acepromazine (120 mg/kg ketamine hydrochloride [5%] and 1 mg/kg acepromazine [1%]), and ketamine–xylazine (120 mg/kg ketamine hydrochloride [5%] and 1 mg/kg xylazine [2%]) wer…

Origin and ploidy of multipronuclear zygotes
2000
Recently, several authors have proposed strategies for correction of triploidy based on the removal of the extra pronucleus at the zygote stage. In the present bioassay, the following were analysed: (1) the different factors that can induce the formation of multipronuclear zygotes in mammals; (2) the different morphological patterns established according to the number of pronuclei and polar bodies that can be observed at the zygote stage and used to distinguish the origin of multipronuclear zygotes; and (3) the pattern of chromosomal segregation during the first mitotic division and ploidy status of the resulting preim-plantation embryos. Such an analysis shows that the morphological crite…
Safety and effectiveness of intravenous morphine for episodic breakthrough pain in patients receiving transdermal buprenorphine.
2006
Supplemental dosing of an opioid is the main treatment suggested to manage breakthrough pain in cancer patients. The intravenous route has been proven to be safe and effective, providing rapid analgesia in patients receiving oral morphine. Transdermal buprenorphine (TTS-BUP) is increasingly used in cancer pain management, but this drug has been labeled as a difficult drug to use in combination with other opioids. The aim of this open-label study was to verify the safety and effectiveness of intravenous morphine (IV-MO) for the treatment of episodic pain in cancer patients receiving TTS-BUP. A consecutive sample of 29 cancer patients, who were treated with TTS-BUP, reported an acceptable bas…
