Does Preoperative Treatment with a Gonadotropin-Releasing Hormone Agonist Improve the Outcome of Endometrial Resection?
1998
Abstract Study Objective. To verify if more favorable long-term results of endometrial resection can be obtained with preoperative gonadotropin-releasing hormone (GnRH) agonist treatment. Design. Multicenter, randomized, controlled trial (Canadian Task Force classification I). Setting. Tertiary care academic department. Patients. Sixty-three premenopausal women with established menorrhagia. Intervention. Eight weeks of goserelin depot treatment before endometrial resection or immediate surgery in the early proliferative phase of the cycle. Measurements and Main Results. Variations in menstrual patterns and bleeding scores as well as overall degree of satisfaction with treatment were determi…
Aluminum Chloride versus Electrocauterization in Periapical Surgery: A Randomized Controlled Trial
2019
The aim of this study was to evaluate the efficacy of 2 hemostatic agents in periapical surgery and its relationship with patient- and tooth-dependent variables.A prospective study was designed with 2 randomized parallel groups established according to the hemostatic agent used: aluminum chloride or electrocauterization. The surgeon and 2 independent blinded observers examined the initial and final bleeding and recorded it as 0 (no hemorrhage control), 1 (slight but apparent intermittent bleeding), or 2 (complete hemorrhage control). The following patient- and tooth-dependent variables were collected: sex, age, smoking habit, plaque index, and position.Sixty patients with a periapical lesio…
Surgical Treatment in Symptomatic Chiari Malformation Type I: A Series of 25 Adult Patients Treated with Cerebellar Tonsil Shrinkage
2019
Background: The variety of symptoms and radiological findings in patients with Chiari malformation type I makes both the indication for surgery and the technical modality controversial. We report our 5-year experience, describing our technique and critically evaluating the clinical results. Methods: Between 2012 and 2016, 25 patients (15 female and 10 male; mean age 39.2 years) underwent posterior fossa decompression for Chiari malformation type I. Their clinical complaints included headache, nuchalgia, upper limb weakness or numbness, instability, dizziness and diplopia. Syringomyelia was present in 12 patients (48%). Suboccipital craniectomy was completed in all cases with C1 laminectomy …
Pain-induced alterations in the individual non-esterified fatty acids in serum.
1979
Changes of individual non-esterified fatty acids in serum were studied in 7 metabolically healthy patients, suffering from idiopathic trigeminal neuralgia, who underwent electrocoagulation of gasserian ganglion under neurolepthypalgesia. The mean concentration of fatty acids increased by about 40% during the strong surgical pain stimulus. The increased lipolysis affected all individual fatty acids in proportion to the ratio of their presence in adipose tissue. The mechanism of pain-induced activation of lipase and possible consequences of alterations in individual non-esterified fatty acids are discussed.
Radiofrequency, high-frequency, and electrocautery treatments vs partial inferior turbinotomy: microscopic and macroscopic effects on nasal mucosa.
2009
Objective To compare the microscopic and macroscopic effects of radiofrequency, high-frequency, and electrocautery therapies with partial inferior turbinotomy in the treatment of nasal obstruction caused by inferior turbinate hypertrophy. Design Nonrandomized controlled trial. Setting Department of Otolaryngology–Head and Neck Surgery, University of Genoa. Patients The study included 80 patients affected by nasal obstruction from hypertrophied inferior turbinates. Interventions Homogeneous patient groups A, B, C, and D underwent radiofrequency, high-frequency, and electrocautery treatments and partial inferior turbinotomy, respectively, to surgically reduce hypertrophied inferior turbinates…
Small-diameter hysteroscopy with Versapoint versus resectoscopy with a unipolar knife for the treatment of septate uterus: A prospective randomized s…
2007
Abstract Study objective To compare 2 procedures for metroplasty: resectoscopy with monopolar knife versus small-diameter hysteroscopy fitted with a Versapoint device. Design Prospective randomized study (Canadian Task Force classification I). Setting Endoscopic gynecology units at tertiary care university hospitals. Patients One hundred-sixty patients with septate uterus and a history of recurrent abortion or primary infertility undergoing hysteroscopic metroplasty from 2001 to 2005. Interventions Hysteroscopic resection of the uterine septum performed with either a 26F resectoscope with unipolar knife (80 women, group A) or a 5-mm diameter hysteroscope with Versapoint device (80 women, gr…
Permeability of the rat bladder to Cisplatinum under different conditions: comparison with Mitomycin C and Adriamycin.
1983
In 50 female Sprague-Dawley rats the absorption of Cisplatinum through the bladder wall was studied. Under different conditions, including cystitis and electrocoagulation of the bladder mucosa, the absorption was low and the measureable serum concentrations did not exceed 2.64 micrograms/ml. The influence of Tween 80--a non-ionic surfactant--on the absorption is investigated. The results are compared with those found for Adriamycin and Mitomycin C under identical conditions.
Electrocoagulation treatment of peat bog drainage water containing humic substances
2015
Abstract Electrocoagulation (EC) treatment of 100 mg/L synthetic wastewater (SWW) containing humic acids was optimized (achieving 90% CODMn and 80% DOC removal efficiencies), after which real peat bog drainage waters (PBDWs) from three northern Finnish peat bogs were also treated. High pollutant removal efficiencies were achieved: Ptot, TS, and color could be removed completely, while Ntot, CODMn, and DOC/TOC removal efficiencies were in the range of 33–41%, 75–90%, and 62–75%, respectively. Al and Fe performed similarly as the anode material. Large scale experiments (1 m3) using cold (T = 10–11 °C) PBDWs were also conducted successfully, with optimal treatment times of 60–120 min (applying…
Epidural hematoma after cochlear implantation in a 2.5-year-old boy.
2005
OBJECTIVE Report a case of an epidural hematoma after cochlear implantation in a 2.5-year-old boy, the diagnostic and therapeutical emergency management, as well as the postinterventional course and rehabilitation of the child. STUDY DESIGN Retrospective case review. PATIENT Two and a half-year-old boy, suffering from early onset, profound sensorineural hearing loss had been diagnosed at an age of 1.5 years, which had been more severe on the right side initially, but had progressed to bilateral deafness. INTERVENTION AND COMPLICATION: Cochlear implantation on the left side, followed up by an extensive epidural hematoma, causing intracranial compression with a midline shift of 15 mm to the r…
Temporal retrogasserian resection of trigeminal root versus controlled elective percutaneous electrocoagulation of the ganglion of gasser in the trea…
1972
In his experience with 531 surgical procedures for the relief of trigeminal neuralgia between 1955 to 1970, the author developed a strong preference for the percutaneous electro-coagulation of the gasserian ganglion. Although the method was repeatedly modified in the early years, a standardized technique of controlled, selective and fractional coagulation in the semiawake state of neurolept-anaesthesia was used since 1963 in 183 of his 311 patients, treated in this manner. The advantages of the method, particularly in comparison to open intracranial root sections, are: Minimal operative risk, control of operative effect during the operation, small sensibility deficit, low rate of complicati…
