Photobiomodulation therapy reduces postoperative pain after third molar extractions: A randomized clinical trial
2020
Background To assess the efficacy of PBMT on reducing postoperative pain scores in patients submitted to third molar extractions. Material and Methods A randomized controlled trial (ReBEC:RBR-94BCKZ) was designed according to the SPIRIT and followed the CONSORT. Patients were randomly allocated according to control or PBMT groups. PBMT consisted of the application of GaAlAs laser (808nm;50mW) applied in six points (1.23 min;11 J/cm2) after extraction. Pain scores were assessed using the Visual Analogue Scale (VAS) in millimeters evaluated after 6 (T6), 24 (T24), and 48 (T48) hours. The Wilcoxon Mann–Whitney test was used to check for possible associations between VAS scores and treatment gr…
Effect of lingual-based flap design on postoperative pain of impacted mandibular third molar surgery : split-mouth randomized clinical trial
2020
Background The extraction of third molars is one of the most common procedures in oral and maxillofacial surgery clinic. Surgical extraction involves the manipulation of both soft and hard tissues, so the patient usually experiences pain, swelling, and trismus in the immediate post-operative period. Several studies have been conducted using different types of surgical flaps to provide access with the least possible damage of soft tissues. Designing and implementing an optimum flap, which provides easier technique, better visibility, minimal post-operative complications, and best healing, is an aspired goal of every oral surgeon. This study aimed to compare lingual-based four-cornered flap w…
How is oral health education conducted in Finnish health centers?
1995
The oral health education (OHE) given in Finnish health centers is mostly implemented by dental assistants and hygienists. However, there is no exact information concerning the distribution of OHE work and the working methods among individual health educators. The aims of this study were to assess 1) the time used for OHE by the dental professionals who bear most of the responsibility for OHE in health centers, and to evaluate 2) the collaboration between OH-educators and the parents of schoolchildren, school personnel and the other health care personnel and 3) the sources of the OHE knowledge and skills of these OH-educators and their methods according to their work load. The data for this…
Multilayer amniotic membrane transplantation in severe ocular graft versus host disease
2001
To clarify the usefulness of multilayer amniotic membrane transplantation in an unusual case of calcareous corneal degeneration in a patient with graft-versus-host disease.A 20-year-old Caucasian woman had bilateral calcareous corneal degeneration of one year of evolution, secondary to graft-versus-host disease. Treatment for both eyes with topical steroids and antibiotic ointment was not successful. Right eye had a spontaneous corneal perforation, and a three-layer circle amniotic membrane graft was applied to the whole cornea.During a follow-up period of 20 months we observed stability of the corneal epithelium and stroma. The amniotic membrane-covered area showed rapid epithelization, re…
Context, remember–know recognition judgements, and ROC parameters
2007
Recent work (e.g., Dunn, 2004; Heathcote, 2003) has questioned the necessity of postulating two processes to explain recognition memory. As part of this trend, strength theories of the remember-know methodology have gained in support. We present three experiments with pictorial material in which we force participants to use differential contextual information at test. Participants were required to give remember-know judgements and confidence ratings for each test stimulus. Hits, false alarms, remember-know data, and discrimination indices indicated systematic variations as a function of the availability and use of contextual information. Moreover, when we normalised the receiver operating c…
Long-term evaluation of quality of life and gastrointestinal well-being after segmental colo-rectal resection for deep infiltrating endometriosis (EN…
2019
Purposes: The primary objective is to assess the long-term quality of life (QoL) and gastrointestinal well-being in patients with endometriosis (DIE) who underwent segmental resection (SR), through specific questionnaires focused on endometriosis and specific gastrointestinal evaluation. The secondary objectives are represented by the evaluation of peri-operative and post-operative outcomes of the procedure. Methods: This observational cohort study ENDO-RESECT (ClinicalTrials.gov ID: NCT03824054) reports all clinical data about women who underwent SR for DIE between October 2005 and November 2017. In the part of the study dedicated to the QoL assessment, the questionnaires adopted were the …
Innervated Island Flaps in Morphofunctional Vulvar Reconstruction
2000
In this article, the authors present their own experience in vulvar reconstruction following vulvectomy using two different innervated island flaps according to the size and site of the defect. Island-flap mobilization is possible thanks to the rich blood supply of the perineal region. The methods described are a "V-Y amplified sliding flap from the pubis" and a "fasciocutaneous island flap" raised from one or both gluteal folds. The V-Y amplified sliding flap from the pubis is indicated when the defect is symmetric and located anteriorly. This flap is harvested from the pubis and vascularized by the deep arterial network of the pubis. Sensory innervation is provided by branches of the ileo…
Ovarian Endometrioid-like Yolk Sac Tumor Treated by Surgery Alone, with Recurrence at 12 Years
1999
Abstract We describe the case of a stage Ia endometrioid-like yolk sac tumor (YST) of the ovary, which was originally misdiagnosed as a malignant struma ovarii and not treated with adjuvant chemotherapy. After 12 years, a contralateral dermoid cyst was excised along with a small omental nodule of partially necrotic and calcified endometrioid-like YST. No tumor was detected in several other biopsy specimens, and a peritoneal lavage was negative for tumor cells. Since there was no evidence of remaining tumor and the serum α-fetoprotein (AFP) level was normal after the second operation, the patient was followed. Serial serum AFP levels remained normal for 4 months. At a second-look laparotomy …
Salvage (tertiary) breast reconstruction after implant failure
2011
Summary Background Salvage breast reconstruction is defined as a complete revision of a previous reconstruction in case of unsatisfactory results or failure of primary or secondary breast reconstruction. We have termed this ‘tertiary breast reconstruction'. This article presents our experience with tertiary reconstructions, including the indications, method of reconstruction and outcomes. Methods A retrospective note review was performed for all patients who underwent breast reconstruction with autologous tissue under one surgeon between 2002 and 2009 at the University Hospital, Ghent. Out of these 688 patients, 54 patients (7.8%) required tertiary surgery with autologous tissue after failu…
Impact of the line of sight on toric phakic intraocular lenses for hyperopia
2003
We present a hyperopic patient with a decentered line of sight in whom the residual refractive error after toric phakic intraocular lens (TP IOL) implantation was improved by displacement and individualized treatment. A 35-year-old woman presented with asthenopic complaints 2 months after bilateral TP IOL implantation and IOL rotation 4 weeks later. Examination revealed the line of sight to be nasally and inferiorly decentered in relation to the center of the pupil. A more nasal reenclavation of the TP IOL decreased the coma, and the uncorrected visual acuity was 20/20. We conclude that line of sight should be measured before TP IOL implantation, especially in hyperopic eyes.
