Effects of passiflora incarnata and midazolam for control of anxiety in patients undergoing dental extraction
2017
Background Anxiety symptoms are frequently observed in dental patients, whether they are undergoing simple or more invasive procedures such as surgery. This research aimed to compare the effects of Passiflora incarnata and midazolam for the control of anxiety in patients undergoing mandibular third molar extraction. Material and Methods Forty volunteers underwent bilateral extraction of their mandibular third molars in a randomized, controlled, double-blind, crossover clinical trial. Passiflora incarnata (260 mg) or midazolam (15 mg) were orally administered 30 minutes before surgery. The anxiety level of participants was evaluated by questionnaires and measurement of physical parameters, i…
The ocular penetration of oral sparfloxacin in humans
1994
The penetration of sparfloxacin into the aqueous humor after oral administration was studied in 28 patients undergoing cataract surgery. Each patient received a single, oral dose of 400 mg of sparfloxacin. In eight other patients scheduled to undergo vitreal surgery, multiple daily oral doses were administered for a total amount of 1,000 mg. The aqueous levels were (mean +/- SEM) 0.127 +/- 0.036 microgram/ml to 0.404 +/- 0.159 microgram/ml from two to 24 hours after ingestion. In the vitreous, the mean drug level was 0.840 microgram/ml (range, 0.480 to 2.060 microgram/ml), from 4.3 to 8.0 hours after the most recent oral dose. Blood samples obtained at the same time as vitreous and aqueous …
Parietal subdural empyema as complication of acute odontogenic sinusitis: a case report
2014
Introduction: To date intracranial complication caused by tooth extractions are extremely rare. In particular parietal subdural empyema of odontogenic origin has not been described. A literature review is presented here to emphasize the extreme rarity of this clinical entity. Case presentation: An 18-year-old Caucasian man with a history of dental extraction developed dysarthria, lethargy, purulent rhinorrhea, and fever. A computed tomography scan demonstrated extensive sinusitis involving maxillary sinus, anterior ethmoid and frontal sinus on the left side and a subdural fluid collection in the temporal-parietal site on the same side. He underwent vancomycin, metronidazole and meropenem th…
Endoscopic papillary large balloon dilation in patients with large biliary stones and periampullary diverticula: Results of a multicentric series.
2018
Abstract Introduction Stone extraction represents the most frequent indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic papillary large balloon dilation (EPLBD) is a recent introduced approach consisting of an endoscopic papillary large balloon dilation following limited endoscopic sphyncterotomy (ES), which has been proven to be safe and effective for extraction of large common bile duct (CBD) stones. Peri-ampullary diverticula (PAD) are described in 10–20% of patients undergoing ERCP. Aim of our study is to evaluate efficacy and safety of EPLBD for the extraction of large biliary stones in patients with PAD. Methods The prospectively collected endoscopy databa…
Clear Lens Extraction with Multifocal Apodized Diffractive Intraocular Lens Implantation
2007
Purpose To assess efficacy, safety, predictability, and stability after clear lens extraction (CLE) with multifocal diffractive intraocular lens (IOL) implantation. Design Prospective, nonrandomized, masked observational case series (self-controlled). Participants Two hundred twenty-four eyes of 112 consecutive patients after CLE with bilateral AcrySof ReSTOR Natural IOL implantation. Eyes were divided into myopic (mean spherical equivalent [SE], −6.01±2.71 diopters [D]) and hyperopic (mean SE, +3.86±2.52 D) groups. Methods Monocular and binocular uncorrected distance visual acuity (VA), best-corrected distance VA, uncorrected distance near VA, and best distance-corrected near VA were recor…
Hepatic extraction of isosorbide dinitrate in cardiac patients
1983
Hepatic extraction of organic nitrates, including that of isosorbide dinitrate (ISDN), has been thought to be nearly complete in man but has never been directly measured. We examined the time course of plasma ISDN and metabolite concentrations in arterial and hepatic venous blood in four cardiac patients receiving an intravenous ISDN infusion. Apparent hepatic extraction of ISDN was high (90%) at the beginning of infusion but fell to about 44% 1 hr after termination of infusion. The decrease in ISDN concentration gradient across the liver correlates with an increase in plasma isosorbide-5-mononitrate concentration, but a cause-and-effect relationship resulting from metabolite inhibition can…
Indication and technique for the reconstruction of nerve defects in head and neck.
1974
Summary Although the results of peripheral nerve repair have been greatly improved in the last years following the introduction of microsurgery and increased application of free autologous nerve transplants, the use of restorative neuroplasty in maxillofacial surgery has been limited. Prompted by the successful reports on modern neuroplasty, we have introduced the use of autologous nerve transplant to bridge lesions of various cranial nerves. Our experience is based on the treatment of traumatic and tumour-induced defects of the facial nerve, inferior alveolar nerve, accessory and lingual nerve. The anastomosis of nerve was accomplished exclusively under the surgical microscope and microsur…
Determinants of inappropriate hospitalization in cataract surgery in the south of Italy: a retrospective study
2017
Purpose To analyze the frequency of inappropriate hospitalization in cataract surgery and the type of related determinants. Methods A nested retrospective case–control study was carried out on 2708 consecutive cataract surgery patients operated between January 2013 and Decem- ber 2015. All cases with inappropriate hospitalization (day surgery or ordinary hospitalization) were com- pared with a control group of cases treated in an appropriate (day service) regimen. The predictive value for inappropriate admissions to the hospital was assessed using a logistic regression model. Significant variables from the univariate analysis were included in a multivariate model. Results Forty-five cases (…
Osteonecrosis of the jaws by intravenous bisphosphonates and osteoradionecrosis : a comparative study
2009
Aims: We analyze the possible clinical differences between bone jaw exposed areas in ONJ (osteonecrosis of the jaws) and ORN (osteoradionecrosis). Patients and method: Group 1 was composed with 53 ONJ cases and group 2 with 20 ORN cases. In both groups we analyzed, the major size of the exposed bone areas, the number of exposed areas, the location on the jaws and the presence of others associated and severe complications, such as skin fistulas and jaw fractures. We also investigated the possible local aetiology or trigger factor of the lesions. Results: The major size of the bone exposed areas was 2.29±2.02(mean ± std.dev) in group 1 and 2.7±2.9 (mean ± std.dev) in group 2 (p>0.05). The num…
Visual Acuity and Contrast Sensitivity in Eyes Implanted with Aspheric and Spherical Intraocular Lenses
2009
Purpose To compare visual acuity and contrast sensitivity (CS) in eyes implanted with aspheric and spherical intraocular lenses (IOLs) after cataract surgery. Design Randomized, prospective study. Participants Five hundred twenty-four eyes from 262 cataract surgery patients implanted with 2 IOL models: the AcrySof IQ (262 eyes) and AcrySof SN60AT (262 eyes; Alcon Laboratories, Fort Worth, TX). Methods High-contrast photopic best-corrected distance visual acuity (BCVA) and CS under photopic (85 cd/m 2 ) and mesopic (6 cd/m 2 ) conditions were measured. Pupil diameter was analyzed for distance vision under both lighting conditions. Follow-up was carried out for 6 months in all patients. Main …
