Metagenomic investigation of bacteria associated with dental lesions : a cross-sectional study
2019
Background Dental caries is considered as one of the most significant global health problem over the world. Dental caries initiates from bacterial shifts within the supragingival biofilm, then a polymicrobial biofilm is formed on the surface of tooth, and finally various bacterial species aggregate in a complex-organized manner. The exploiting variability in 16S rRNA gene sequence has been considered as a cost-efficient high-throughput characterization approach in human oral microbiome investigations. The aim of this study is to characterize bacterial species associated with superficial dental biofilm, underlying carious dentine and root caries lesion by16S rRNA gene-based metagenomic analy…
Outpatient management of proctologic disease. Which techniques for local anesthesia? The experience of a single center
2019
Introduction. Since 1899 outpatient management of surgical patients had been increasing, becoming the best option when possible. In 1988 was described the first experience of outpatient management of proctologic disease. Advances in local anesthesia techniques have improved the outpatient approach to surgical disease, particularly in patients with proctological diseases. Methods. From 2010 to 2016, 1160 patients who needed surgery for proctologic disease have been recruited: 239 hemorrhoidectomies using the variant of Milligan Morgan technique described by Phillips, 45 trans-anal hemorrhoidal DE-arterialization (THD), 315 sphincterotomies, 12 anal polypectomies, 230 loop seton positions, 65…
Second study on the recurrence risk of isolated esophageal atresia with or without trachea-esophageal fistula among first-degree relatives: no eviden…
2013
BACKGROUND Esophageal atresia with/without trachea-esophageal fistula (EA/TEF) denotes a spectrum of severe congenital malformations. The aim of this systematic study was to determine both the recurrence risk for EA/TEF, and the risk for malformations of the VATER/VACTERL association spectrum, in first-degree relatives of patients with isolated EA/TEF. METHODS A total of 108 unrelated patients with isolated EA/TEF were included. These individuals had 410 first-degree relatives including 194 siblings. The presence of EA/TEF and malformations of the VATER/VACTERL association spectrum in relatives was systematically assessed. Data from the EUROCAT network were used for comparison. RESULTS None…
Transanal hemorrhoidal dearterialization versus Milligan-Morgan hemorrhoidectomy in grade III/IV hemorrhoids.
2019
La terapia delle emorroidi di III e IV si basa sul trattamento chirurgico. All’emorroidectomia secondo Milligan Morgan (MM), da molti chirurghi considerata il gold standard, si affiancano attualmente metodi chirurgici considerati meno invasivi come la Procedura per Prolasso ed Emorroidi (PPH) e la dearterializzazione emorroidaria transanale (THD). Gli Autori hanno voluto confrontare in un trial prospettico e randomizzato la emorroidectomia secondo MM e la THD nel trattamento di emorroidi di III e IV grado valutandone i risultati a breve e medio termine. Materiali e metodi: Tra gennaio 2010 e marzo 2013 sono stati reclutati 87 pazienti con emorroidi di III e IV grado secondo la classificazio…
"Only Spinal Fixation" as Surgical Treatment of Cervical Myelopathy Related to Ossified Posterior Longitudinal Ligament: Review of 52 Cases.
2020
Background Ossification of the posterior longitudinal ligament (OPLL) is a hyperostotic condition resulting in a progressive narrowing of the spinal canal and subsequent neurologic deficits. Although systemic and local factors in combination with genetic abnormality have been considered in its etiopathogenesis, OPLL remains a poorly understood pathology. Surgical management of OPLL and the choice of the most appropriate treatment are still controversial issues. Here the authors report a series of OPLL-affected patients treated by “only-fixation” technique. Methods Between June 2012 and June 2019, 52 patients having OPLL were treated by a surgical strategy involving only spinal fixation with…
Laparoscopic surgery for isolated inguinal node relapse of high grade serous ovarian cancer using a bipolar combination instrument
2020
Abstract Objective To demonstrate step-by-step minimally invasive surgical technique for dissection of isolated inguinal node relapse of high grade serous ovarian cancer. Methods A 54-year-old woman, BRCA1 +, underwent to open abdominal total hysterectomy, bilateral salpingo-oophorectomy, total omentectomy, pelvic and aortic lymphadenectomy with zero residual disease, for high grade serous ovarian carcinoma FIGO stage IIB. After surgery, patient underwent platinum-based chemotherapy for six cycles and follow-up examinations every 3 months for the first year and biannual for the second one. Abdominal TC-PET scan after 18 months revealed a right distal iliac external/inguinal nodal relapse (S…
Virtual endoscopy of the inner ear and the auditory canal.
2000
To assess the role of virtual endoscopy (VE) in the examination of intracisternal structures and of the inner ear, we studied the anatomy of the labyrinth and internal auditory canal using the original CT slices and VE on the unaffected side in three female and three male patients, age range 3–46 years, with contralateral retrocochlear hearing loss. We also examined seven patients with different pathological findings. VE was performed using an advanced postprocessing program with high- resolution 3D data sets of CT (1–1.5 mm thickness, pitch 1.25) and MRI-CISS-3D (constructive interference in steady state) images of the basal cisterns (1.5 T, slice thickness 0.7–1 mm). VE provides an endosc…
Bifid mandibular canal.
2003
Abstract Purpose: To determine the incidence and characteristics of bifid mandibular canals. Methods: A retrospective study was performed using panoramic radiographs of 2012 patients subjected to dental treatment in the Dental Clinic of the Valencia University Dental School (Valencia, Spain) between 1996 and 1999. The goal was to investigate the presence of double mandibular canals. Results: The extraoral panoramic radiographs revealed a total of 7 images suggestive of bifid canals. Mandibular computed tomography revealed the existence of this anatomic variant in 2 of 3 patients. An analysis was performed on the incidence of this type of image in extraoral panoramic radiography, its possibl…
Evaluation of volumetric measurements on CBCT images using stafne bone cavities as an example
2015
Adisen, Mehmet Zahit/0000-0002-5493-8390; Yilmaz, Selmi/0000-0001-9546-6548; Yilmaz, Selmi/0000-0001-9546-6548; ATIL, Fethi/0000-0002-8286-4819 WOS: 000365269900009 PubMed: 26116844 Background: The aim of the present study is to evaluate the efficacy of CBCT in volume measuring using Stafne Bone Cavities (SBC) as an example. Material and Methods: The study was conducted with 14 subjects with SBC detected on panoramic radiographs. In order to evaluate lesions volumetric dimensions, CBCT images for each patient were captured. Files in Digital Imaging and Communications in Medicine (DICOM) format were transferred into a medical image processing program (ITK-SNAP 2.4.0) and volume in mm(3) of t…
Characteristics of anatomical landmarks in the mandibular interforaminal region: A cone-beam computed tomography study
2011
Objectives: This study was conducted to assess appearance, visibility, location and course of anatomical landmarks in mandibular interforaminal region using cone-beam computed tomography (CBCT). Study design: A total of 96 CBCT examinations was re-evaluated to exploit anatomical landmarks. The examinations used the Promax 3D CBCT unit. A sole examiner carried out all the measurements. Visibilities of the anatomical landmarks were scored using a four-point rating scale. Results: The mandibular foramen, anterior loop, incisive canal and lingual foramen were observed in 100,84,83,49 % of the images, respectively. The mean size, diameter and width of anterior loop, incisive canal and lingual fo…
