Clinical and radiographical evaluation of non-syndromic hypodontia and hyperdontia in permanent dentition

Objectives: The purpose of this study was to evaluate the clinical and radiographical characteristics of non-syndromic hypodontia and hyperdontia in the permanent dentition.Study design: This study included 139 patients. Clinical and radiographical examinations were carried out by two examiners. Number and localization of missing or supernumerary teeth, and pathologies associated with the teeth, were recorded. Other teeth in the mouth were also examined for the presence of additional dental anomalies.Results: A total of 256 congenitally missing teeth were observed in 102 patients, and 73 supernumerary teeth were observed in 37 patients. The rate of missing teeth was much higher in females (67.6 %) than males (32.4 %) and in the maxilla (64.5 %) than mandible (35.5 %). The rate of supernumerary teeth was slightly higher in males (59.5 %) than females (40.5 %) and in maxilla (53.4 %) than mandible (46.6 %). The most common hypodontia type was mild to moderate hypodontia (62.7 %) and the most observed hyperdontia was a single supernumerary tooth (54.1 %). Microdontia, talon cusp, taurodontic molars were observed in 18.6 % of patients with hypodontia; and microdontia and dilacerated molars were observed in 8.1 % of patients with hyperdontia.Conclusions: Although missing and supernumerary teeth are asymptomatic in most cases, they may lead to malocclusions, aesthetic, functional and psychological problems

Chronic Tubal Torsion Mimicking a Tubo-Ovarian Abscess; Case Report

Isolated tubal torsion is an uncommon cause of acute abdominal pain with the incidence of about 1/1,500,000 women. Here, we present a 36-year-old patient who was referred to us with the diagnosis of tuboovarian abscess resistant to medical treatment. Although she was hospitalized and was medicated, her complaints did not reduce. Diagnostic laparoscopy was performed, and salpingectomy was performed on account of tubal torsion

The effect of vaginal bleeding and non-spesific pelvic pain on pregnancy outcomes in subchorionic hematomas cases

Objectives: To determine the clinical differences and factors affecting early pregnancy outcome in the first and early second trimester subchorionic hematoma cases.  Material and methods: This study involved with the retrospective analysis and evaluation of 81 cases diagnosed with subchorionic hematoma. The patients were grouped according to the gestational periods, symptoms at the time of admission, ratio of surrounding hematoma to the gestational sac, and whether there was a pregnancy loss. The groups were compared according to the clinical features and pregnancy outcomes.  Results: The ratio of surrounding hematoma to the gestational sac in the group with pregnancy loss was significantly higher (p = 0.002). When the cut-off value was 35.5%, it could determine the possibility of a complication in pregnancy with 70% sensitivity and 75% specificity. Nonspecific pelvic pain were significantly higher in the pregnancy loss group than in the other group. Logistic regression analysis was performed to determine the effect of these two parameters on the pregnancy outcome. Although the presence of non-specific pelvic pain is more in the group with pregnancy loss; there was no effect of on pregnancy outcome (p = 0.141). The risk of pregnancy loss increased 4.5 fold if the ratio of ScH to gestational sac was above 35% (p = 0.027).  Conclusions: In the cases of subchorionic hematoma, we concluded that when the ratio of surrounding hematoma to the gestational sac increased and when it was accompanied by nonspecific pelvic pain, the hospitalization period of the patients increased and the ratio of pregnancy loss was higher

Rudimentary horn pregnancy — ten years of experience

Objectives: This study aimed to evaluate data on early diagnosis and therapeutic management of rudimentary hornpregnancy (RHP).Material and methods: Patients diagnosed with RHP at a tertiary center between for two periods of 2008–2012 and2013–2018 were analysed retrospectively. We obtained information of patients from hospital electronic archive registrationsystem. Data on demographic characteristics, clinical presentation, gestational age at presentation, presenting symptoms,diagnostic methods, and therapeutic management were noted and analysed by descriptive statistical method. Demographicdatas, the complaint of patient’s admission to hospital, history of cesarean section, preliminary diagnosis and intraoperativediagnosis were compared between periods of 2008–2012 and 2013–2018.Results: A total of 14 RHP patients were included. Eight (57.1%) of these patients were diagnosed between 2008–2012 (Group1), whereas six patients (42.9%) were diagnosed between 2013–2018 (Group 2). Rudimentary horn was non-communicatingin 13 patients (92.8%). Communicated form was observed in 1 patient in group 1. RHP was diagnosed on the left side in ninepatients (64.2%). Six of these patients were observed in group 1 and 3 were in group 2. The pre-rupture diagnosis was madein 10 (71.4%) patients. Six (100%) of 10 patients were in group 2. In addition, in group 1, four patients (50%) experiencedintraoperative RHP rupture. RHP was diagnosed before rupture in 2 (33.3%) patients in group 2.Conclusions: It is an indication of advanced ultrasonographic technology as well as increased carefulness on the physicianside and raised alertness on the patient side that today both RHP and preoperative rupture of RHP are less frequent.Still, further awareness is required among physicians of the necessity of excision of a rudimentary horn that is detectedat the time of C-section

Thermal necrosis-aided dental implant removal:A rabbit model pilot study

The significant advances in the materials and biological aspects of dental implants haven?t completely eradicated the implant failures. The removal of osseointegrated but otherwise failed implants present several challenges including adjacent tissues damage and necessity of bone augmentation for reimplantation. Controlled thermal necrosis has emerged as an alternative technique to aid removal of osseointegrated dental implants with minimal to no defect to healthy bone or surrounding tissues. This study aimed to evaluate the thermal necrosis-aided implant removal method in a rabbit osseointegration model. A total of 8 male New Zealand rabbits were used in the study. Two dental implants were placed on each femur of the rabbits. Heating of the implants was performed after 7 weeks following the implantation. Heating was done by contacting the tip of an electrosurgey tool in monopolar mode at different power settings and contact durations (5W ? 2 seconds, 5W ? 10 seconds, and 10 W ? 10 seconds). No heating was done on the control group. Implant stability right after implantation, before heat application and after heat application was determined using an Osstell? Mentor Device. Following the removal of implants histological analyses were performed to determine the effects of heat application at cellular level. ISQ values of the 10W-10s group was significantly lower compared to the other groups (p<0.001). No indication of progressive necrosis or irreversible damage was observed in any of the groups. However, the percent of empty-apoptotic lacunae were statistically higher in the 5W-10s and the 10W-10s groups compared the control and the 5W-2s groups. Within the conditions of this study, we conclude that heat application with an electrosurgery tool using monopolar mode at 10W power for 10 seconds is optimal for reversing osseointegration with no extensive or progressive damage to the bone

Factors associated with complications of vaginal hysterectomy in patients with pelvic organ prolapse — a single centre’s experience

Objectives: The study aimed to examine the predisposing factors that play a role in the development of complications in patients undergoing vaginal hysterectomy. Material and methods: This retrospective analysis was performed on data provided from 239 patients who underwent vaginal hysterectomy due to uterine prolapse at a single centre between January 2008 and August 2018. Complications were defined according to Clavien-Dindo classification of complications. The patients were divided into two groups: with and without complications. We built a model using multivariable logistic regression to examine the relationships between complications and five candidate predictors. Results: Intra/postoperative complications developed in 30 patients, and the complication rate was found to be 12.5%. 87.2% of the reported complications were classified as Grade ≤ 2 according to Clavien-Dindo system. It was found that complications were associated with factors such as intraoperative concurrent salpingo-oophorectomy [Odds ratio (OR): 1.24 (1.1–1.4)], low preoperative haemoglobin [OR: 0.96 (0.94–0.98)], uterine weight [OR: 2.69 (2.62–2.76)], and long operation time [OR: 1.04 (1.02–1.07)]. History of pelvic surgery was not found to increase complication rate [OR: 1.11 (0.96–1.27), p = 0.13]. Our multiple logistic regression model correctly classified 74% of participants within the Receiver Operating Characteristic (ROC) curve. Conclusions: Preoperative anaemia, large uterus and concomitant adnexectomy were found to be factors associated with complications during and after vaginal hysterectomy for pelvic organ prolapse

Evaluation of spinal-paraspinal parameters to determine segmentation of the vertebrae

Purpose: We aimed to evaluate whether lumbar vertebrae can be correctly numbered using auxiliary parameters. Material and methods: Vertebra corpus shape, O’Driscoll classification, lumbosacral axis angle, last two square vertebra dimensions, orifice of right renal artery (RRA), orifice of celiac truncus (CT), orifice of superior mesenteric artery (SMA), vena cava inferior confluence (CVC), abdominal aorta bifurcation (AB), and iliolumbar ligament were evaluated in this study. Results: Lumbosacral transitional vertebrae (LSTV) were observed in 13 (9%) patients. The most common locations of the paraspinal parameters were: RRA: L1 vertebrae (45%), SMA: L1 vertebrae (66%), CT: T12 vertebrae (46%), AB: L4 vertebrae (63%), and CVC: L4 vertebrae (52%). Conclusions: According to the results of our study, no single parameter in the magnetic resonance imaging can accurately indicate the number of vertebrae without counting the levels. As a result, we believe that these parameters may be suspicious in terms of the presence of LSTV rather than the correct level

Prediction of degree of carotid stenosis with the transluminal attenuation difference ratio

PURPOSEWe aimed to assess the diagnostic performance of transluminal attenuation difference (TAD) in predicting the severity of internal carotid artery (ICA) stenosis.METHODSThe study cohort consisted of 48 patients with 70%) stenosis compared with control arteries and low-moderate stenosis. A TAD ratio cutoff of 4.5 predicted 70%–99% stenosis with a sensitivity of 100% and specificity of 93%. The inter- and intraobserver agreements in TAD measurements were almost perfect (ICC, 0.89–0.86).CONCLUSIONAssessment of TAD ratio predicts the degree of stenosis in concordance with NASCET system

MRI quantification techniques in fatty liver: the diagnostic performance of hepatic T1, T2, and stiffness measurements in relation to the proton density fat fraction

PURPOSENonalcoholic fatty liver disease (NAFLD) can progress to liver cirrhosis and is predicted to become the most frequent indication for liver transplantation in the near future. Noninvasive assessment of NAFLD is important for diagnosis and patient management. This study aims to prospectively determine the liver stiffness and T1 and T2 values in patients with NAFLD and to compare the diagnostic performance of magnetic resonance elastography (MRE) and mapping techniques in relation to the proton density fat fraction (PDFF).METHODSEighty-three patients with NAFLD and 26 participants with normal livers were imaged with a 1.5 T scanner. PDFF measurements obtained from the multiecho Dixon technique were used to quantify the liver fat. MRE, native T1 mapping (modified Look-Locker inversion recovery [MOLLI] schemes 5(3)3, 3(3)3(3)5, and 3(2)3(2)5 and the B1-corrected variable flip angle [VFA] method), and T2 mapping values were correlated with PDFF. The diagnostic performance of MRE and the mapping techniques were analyzed and compared.RESULTST1 values measured with the MOLLI schemes and the B1-corrected VFA (P < 0.001), and the stiffness values from MRE (P = 0.047) were significantly higher in the NAFLD group. No significant difference was found between the groups in terms of T2 values (P = 0.127). In differentiation of the NAFLD and control groups, the B1-corrected VFA technique had slightly higher accuracy and area under the curve (AUC) than the MOLLI schemes. In the NAFLD group, there was a good correlation between the PDFF, MOLLI 3(3)3(3)5 and 3(2)3(2)5, and VFA T1 measurements (r=0.732; r=0.735; r=0.716, P < 0.001, respectively).CONCLUSIONLiver T1 mapping techniques have the potential to distinguish steatotic from nonsteatotic livers, and T1 values seem to have a strong correlation with the liver fat content
