Ultrasonographic Evaluation of Soft Tissue Calcifications in the Head and Neck Region Detected on Panoramic Radiographs.

OBJECTIVE: The aim of this study is to present a comparison between panoramic radiographs and USG imaging with a focus on revealing the advantages of USG over radiographs, and to show the distribution of calcifications detected in USG by considering the age and gender. METHODS: A total of 148 patients with soft tissue calcifications as seen on panoramic radiographs were examined with USG imaging. Sialoliths, carotid artery calcifications, tonsilloliths, phleboliths and lymph node calcifications were examined in terms of anatomical localization, distribution and shape. RESULTS: In the USG evaluation of these 148 patients, soft tissue calcifications were observed in 113 (76.4%) patients. The mean age of the patients with calcification was 55.6 ± 13.1 (min: 22-max: 77). Bilateral calcifications were detected in 25 (22.1%) patients, whereas unilateral calcifications were found in 88 (77.9%) patients. While the rates of tonsilloliths, sialoliths, phleboliths, and lymph node calcifications were statistically similar in male and female patients, the rate of carotid artery calcifications was found to be higher in men than in women (P = 0.017). No statistical significance was found between age groups in terms of the formation of soft tissue calcifications (P = 0.117). CONCLUSIONS: Panoramic radiographs may mislead clinicians in the diagnosis and differential diagnosis of soft tissue calcifications in the head and neck region due to the presence of distortion, superpositions, metal artefacts, and ghost images. USG is an important diagnostic tool in determining the localization of soft tissue calcifications that can be confused on two-dimensional radiographs, their relationship with neighboring structures, and defining calcification. It can be used safely in the detection of soft tissue calcifications as it provides dynamic imaging without the use of radiation or contrast material compared to other advanced imaging methods.

Validation of the Turkish version of the Obstetric Quality-of-Recovery score 11 (ObsQoR-11T) after cesarean delivery.

BACKGROUND: To translate and validate the psychometric characteristics of a Turkish version of the Obstetric Quality-of-Recovery score 11 tool used to measure post-cesarean delivery recovery in Turkish-speaking patients. METHODS: After the original English version of the Obstetric Quality-of-Recovery score 11 tool was translated into Turkish; it was psychometrically validated to assess the post-cesarean delivery quality of recovery. Validity, reliability, and feasibility were investigated. The Obstetric Quality-of-Recovery score 11 tool was administered to Turkish-speaking patients on postoperative day 1. On postoperative day 1, a global health visual analog scale was used to assess the patient's perceived global recovery. RESULTS: One hundred and eighty-six patients completed their questionnaires, providing a completion rate of 97.38%. The Spearman rho (ρ) correlation coefficient between the Obstetric Quality-of-Recovery score and global health visual analog scale (0-100 points) was 0.850 at postoperative day 1 following surgery (P < 0.001). Internal consistency, measured using Cronbach's alpha, was 0.822. The split-half coefficient was 0.708. The Obstetric Quality-of-Recovery score differed significantly between the emergency and elective cesarean delivery groups (80 (41-104) vs. 83.3 (51-102); P < 0.05). The test-retest reliability of the Obstetric Quality-of-Recovery score items was more than 0.6 in 82% of cases, indicating good repeatability and reliability. CONCLUSION: The Obstetric Quality-of-Recovery score 11 is a valid and reliable tool to measure the post-cesarean quality of recovery in Turkish-speaking patients. The psychometric properties of the Turkish version of the scale to measure the post-cesarean quality of recovery were similar to those of the seminal English version.

Linguistic validation of a widely used recovery score: quality of recovery-15 (QoR-15).

BACKGROUND: The quality of recovery-15 (QoR-15) is a patient reported outcome questionnaire that measures the quality of recovery after surgery and anesthesia. The QoR-15 has been validated in many languages; Turkish version of the QoR-15 has not yet been established. The aims of this study were to translate the QoR-15 questionnaire into Turkish and to perform a full psychometric evaluation of the Turkish version. METHODS: After translating the original English version of the QoR-15 scale into Turkish, the QoR-15T scale was psychometrically validated. This process included validity, reliability, responsiveness, feasibility. The QoR-15T was evaluated before the surgery and 24 h after surgery. RESULTS: A total of 210 patients completed the pre- and postoperative questionnaires, providing a completion rate of 93.75%. The correlation coefficient between QoR-15T score and VAS score was 0.644 on postoperative day 1 (p < 0.001). Inter item Cronbach's alpha was 0.863. Global test-retest concordance coefficient was 0.98 (95% CI: 0.94-1.00). DISCUSSION: The QoR-15T scale is a reliable and valid instrument for evaluating postoperative quality of recovery in Turkish speaking patients. The psychometric characteristics used to assess postoperative quality of recovery were similar to those in the English version.

Anesthesia management for robotic assisted radical prostatectomy. Single center experince.

AIM: The aim of this study was to present our experiences for anesthesia management in patients undergoing robot-assisted radical prostatectomy (RARP) in light of current literature data. MATERIAL AND METHODS: This clinical retrospective study included 103 patients who underwent robot-assisted radical prostatectomy. All patient data were obtained from the patient files and anesthesia follow-up forms. Demographic datas, intraoperative fluids, blood products requirement and blood gas parameters were recorded. RESULTS: A total 15 of 103 patients data were lack, the remaining 88 patients were evaluated. Combination of crystalloid and colloid was used for intravenous fluid management. About 11% of patients required transfusion during surgery. The mean pH and pO2 values of the patients were observed to decrease whereas pCO2 and lactate values increased. DISCUSSION: Radical Prostatectomy can be performed either using open technique as a traditional approach or laparoscopic or robot-assisted technique as a minimally invasive approach. Today, minimally invasive approaches have replaced traditional open prostatectomy. Anaesthesia management of these minimally invasive techniques is very different and challenging from open technique in many aspects. CONCLUSION: Although minimally invasive techniques have good surgical outcomes such as less blood loss, smaller surgical incision, and shorter hospitalization, these techniques bring new problems that anesthesiologists have to deal with. Increased RARP operations has led to the anesthesiologists more likely to encounter perioperative problems. KEY WORDS: Anesthesia, Minimally invasive techniques, Radical prostatectomy.

Analgesic Effectiveness of Ultrasound-Guided Pecs II Block in Central Venous Port Catheter Implantation.

BACKGROUND AND AIM: In oncology patients, central venous port catheter (CVPC) implantation is generally preferred for venous route. However, in this procedure, postoperative pain is often observed. This study aimed to investigate the effectiveness of ultrasound-guided Pecs II block in the management of pain after CVPC placement. METHODS: One hundred and eighty-seven patients who underwent CVPC implantation between January 2017 and August 2018 were included in the study. Patients who underwent Pecs II block under ultrasound guidance were called as the Pecs group, and those who underwent local anesthesia (LA) were referred as the LA group. All procedural parameters were analyzed, including demographic characteristics of patients, visual analogue scores (VAS) at 2nd and 24th hours, and postoperative opioid, and non-steroidal anti-inflammatory drug (NSAID) consumption. RESULTS: The postoperative 2nd hour VAS scores were similar in both groups and were lower than the 24th hour VAS scores. VAS scores at the 24th hour in the Pecs group were significantly lower than the LA group (P = 0.001). While the number of fentanyl rescue doses administered in PACU was similar, the total NSAID consumption in the first 24 hours was higher in the LA group than in the Pecs group. CONCLUSION: In CVPC placement, ultrasound-guided Pecs II block is a more reliable, easily applicable and longer-acting approach than LA infiltration for postoperative analgesia.

Perioperative anesthetic management in a patient with factor XI deficiency undergoing coronary artery bypass graft surgery.

Spontaneous bleeding is rare in patients with factor XI deficiency and significant bleeding usually occurs after a trauma or a surgical procedure. It is difficult to maintain hemostatic balance in these patients. In the present case report, a 68-year-old male patient with no chronic disease was scheduled for elective cardiopulmonary bypass surgery. Eight units of fresh-frozen plasma (FFP) were slowly infused and the operation was initiated with the activated partial thromboplastin time (aPTT) of 34.5, which was 108.7 in the preoperative period. Tranexamic acid bolus was administered before the skin incision and continued throughout the operation. Intraoperative aPTT was measured intermittently and a total of six units of FFP were administered. After 76 minutes of cross-clamp time, the patient was separated from cardiopulmonary bypass without any problem. There is no consensus regarding the management of bleeding during cardiac surgery in patients with factor XI deficiency. The common approach includes normalizing the factor levels via FFP infusion or factor concentrates in the preoperative period, proceeding with surgery following the replacement, and close monitoring of perioperative factor levels and aPTT values.

Complications and pitfalls of central venous port catheters: experience with 782 patients with cancer.

BACKGROUND: The clinical use of port catheters has become widespread because they provide a safe and easy vascular route. Such widespread use of vascular port catheters has revealed early and late complications. AIM: This study was evaluated the early and late noninfectious complications and present precautions and pitfalls to handle these complications. METHODS: The retrospective observational study comprised 801 vascular port catheters inserted into 782 adult patients for various reasons between 2010 and 2018. Patient demographic, indications for port catheter implantation, port catheter types, and insertion sides were noted. Port catheter implantation related early and late complications were recorded. RESULTS: The subclavian vein was selected as a target vein in almost all of the interventions (98.9%). Similarly, right-sided veins were used in about 90% of patients. The most common problem was technical issues related to the interventions. If venous cannulation was challenging, ultrasonography and fluoroscopy guidance roadmap technique were used. Most serious complication was pneumothorax in 7 patients. In the late period, the most common problem was thrombotic occlusion of the catheter. In two-thirds of these patients, thrombolytic therapy for thrombosed port catheters may rescue some catheters and avoid secondary port catheter insertions. CONCLUSIONS: Despite these benefits, port catheters are associated with various complications. However, most of these complications can be effectively prevented by proper techniques and easily applied precautions.

A Novel Technique: Ultrasound-Guided Serratus Anterior Plane Block for the Treatment of Posttraumatic Intercostal Neuralgia.

Serratus anterior plane block has been used for pain management during the acute period of conditions affecting the thorax, such as postthoracotomy recovery, rib fracture, and breast surgery recovery. Here, we report the use of serratus anterior plane block in posttraumatic chronic pain treatment. We describe a case of posttraumatic chronic intercostal neuralgia, in which successful pain relief was achieved via repeated injections of local anesthetic and steroid combinations in the serratus anterior plane under ultrasonographic guidance. This novel technique is easy to administer, reliable, and warrants further investigation with regard to its use for rehabilitation of patients who are experiencing posttraumatic chronic neuropathies of the chest wall.

Efficacy of Two Different Nickel-Titanium Rotary Systems in Retreatment Procedure With or Without Laser-Activated Irrigation: An In Vitro Study.

Objective: The aim of this study was to compare the efficacy of HyFlex EDM (Coltene/Whaledent, Altstätten, Switzerland) and ProTaper Universal Retreatment Nickel-Titanium (NiTi) Systems [The ProTaper Universal Retreatment (PTR), Dentsply Maillefer, Ballaigues, Switzerland] in the removal of the root canal filling materials with or without laser activated irrigation. Materials and methods: The root canals of 60 human mandibular premolars were instrumented with K files up to size 35 at a working length; the step-back procedure was performed in 1 mm increments up to size 50. Next, the teeth were obturated using the lateral compaction technique with gutta-percha and resin-based sealer, and they were randomly divided into two groups (n = 30) according to the retreatment systems: PTR and HyFlex EDM NiTi rotary files. Then, each group was divided into two subgroups (n = 15), laser [photon-induced photo-acoustic streaming (PIPS); Fotona, Ljubljana, Slovenia] activated irrigation and conventional needle irrigation group. Following these procedures, the specimens were evaluated using micro-computed tomography. Results: There was no significant difference between the instrumentation systems regarding the cleaning efficacy (χ2 = 0.754; p = 0.86). Additionally, PIPS method did not have a significant effect on the removal of the filling material compared to conventional needle irrigation. Conclusions: Both instrumentation systems were effective in removing the filling material, but neither was able to remove the filling material completely. PIPS method did not show a significant additional effect regarding the removal of filling material.

A comparative study of cone-beam computed tomography and periapical radiographs in decision-making after endodontic instrument fractures.

PURPOSE: This study aimed to compare the diagnostic efficacies of periapical radiographs (PRs) and cone-beam computed tomography (CBCT) scans on clinicians' decision-making in diagnosing and providing treatment of fractured instruments in root canals during glide path preparation. METHODS: 40 maxillary molar teeth were selected and randomly divided into 4 groups. In each experimental group (n = 10), Hedstroem stainless steel instruments were fractured in mesiobuccal (MB) or distobuccal (DB) root canals. In group 1 (#0.06), group 2 (#0.08), group 3 (#0.10), and group 4 (#0.15), instruments were forced to fracture. PRs and CBCT scans were evaluated and compared. Observers were asked to use the following scoring system to decide whether to: 1. remove the fragment; 2. leave the fragment in situ; 3. bypass the fragment; or 4. use a surgical approach for removing the fragment. RESULTS: CBCT observers mostly decided on removing and bypassing the fractured fragment, while radiograph observers mostly decided to leave fragments in situ. However, there was no significant difference between these parameters when CBCT scans were compared to PRs for decision-making of the fractured instruments (p≥0.05) regarding different sizes of root canal instruments. CONCLUSIONS: In decision-making regarding fractured instruments during glide path preparation, clinicians should strategize treatment options based on variables using high-resolution images that reflect accurate scenarios through PRs or CBCT scans that also take into account low radiation dosage in situ PRs have precedence for a diagnostic approach.

The characteristics and occurrence of the talon cusps in Turkish population: a retrospective sample study.

PURPOSE: The purpose of this study was to figure out the characteristics and occurrence of talon cusps in a sample of Turkish population. METHODS: In this retrospective study, talon cusps in permanent dentition were evaluated on radiographs and intraoral photographs which were obtained from patients who were referred to Oral and Maxillofacial Radiology Department, Faculty of Dentistry, Adnan Menderes University, Aydin, Turkey between January 2013 and January 2014. RESULTS: Talon cusps were observed in 365 of 4116 patients, with a frequency of 8.86 %. There were 208 (57 %) females and 157 (43 %) males with this variation. Maxillary canines were the most affected anterior teeth (40.83 %), followed by lateral incisors (39.60 %) and central incisors (19.55 %). Of the patients, 81 (22.19 %) had type I talon cusp with two periapical pathologies, 114 (31.23 %) had type II talon cusp with four periapical pathologies and 226 (61.91 %) had type III talon cusp with also four periapical pathologies. CONCLUSIONS: The occurrence of talon cusps was higher than other studies reported in the literature, with an exception of the study in Alaskan Eskimos. The most commonly detected type of talon cusp was type III (61.91 %), and dens invaginatus was the most frequent variation observed with talon cusps.

Validation of micro-computed tomography for occlusal caries detection: an in vitro study

Conventional methods of caries detection, including the gold standard of histological examination, have certain disadvantages that must be addressed prior to validating any other diagnostic technique—current or new. Here we evaluated the validity of micro-computed tomography (micro-CT) as an alternative gold-standard technique for caries detection. Sixty teeth with suspected occlusal caries were chosen from a pool of teeth extracted for orthodontic, periodontal, or surgical reasons. Identical reference points were marked on photographs taken for teeth and were used to evaluate each method. Dimensions of caries were assessed by two calibrated examiners using the ICDAS-II visual examination system, bitewing radiographs, and micro-CT. The teeth included in the study were selected randomly from solution before all measurements. For micro-CT, the device was set to 50 kV, 800 µA, pixel size 15 µm (at 1024 × 1024 resolution), and 1° rotation step. NRecon software (SkyScan) was used to obtain reconstructed images. For each diagnostic method, results were compared with histology results using the McNemar test. Receiver operator characteristic (ROC) analysis was also performed for each method (Z-test; p < 0.05). Besides showing a high correlation with histology results, micro-CT yielded the greatest values at the D3 threshold; moreover, accuracy and area under the ROC curve (AUC) values were greatest at the D1threshold. Our results indicate that micro-CT performs as well as or better than histological examination for the purpose of comparing methods for caries detection.
