Online ahead of print. ABSTRACT PURPOSE: This study aimed to compare the students' scores of the spot (spotter/classical/traditional/tag/ring/bell-ringer) test (3D environment) performed in the laboratory with the slide test (gross anatomy images) (2D environment) in the class. The observation of our department regarding both types for practical examination was reported, in terms of exam marks of the students. Bo th are preferred as the practical examination types for gross anatomy course our in medical faculty. METHODS: The 29 blocks' scores in 5 years (2013/2014-2017/2018) belonging to first- and second-year medical students' spot tests and slide tests are evaluated retrospectively and statistically compared. Correlations of the spot tests and the slide tests, besides the correlations between theoretical examinations and the practical examination types, are calculated. RESULTS: Spot test scores were significantly higher (p < 0.05) in nine blocks, while slide test scores were higher significantly (p < 0.05) in fourteen. There was no statistically significant difference between the practical examination types (spot/slide) in six blocks. There were correlations between the spot test and the slide test in all blocks (p < 0.001). CONCLUSION: It is considered that the spot test reflects the success/ability in a 3D environment, while the slide test reflects it in the 2D environment. In conclusion, neither of these two types of examinations stands out absolutely. Both types of examinations have their own features in areas, such as assessment power, applicability, and effect on success. PMID:33687489 | DOI:10.1007/s00276-021-02726-5 View on the web Inoreader.

xlomafota13 shared this article with you from Inoreader Auditory and imaging markers of atypical enlarged vestibular aqueduct Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Mar 9. doi: 10.1007/s00405-021-06700-0. Online ahead of print. ABSTRACT PURPOSE: To characterize the auditory and imaging markers of atypical enlarged vestibular aqueduct (EVA). METHODS: 15 EVA cases (26 ears) confirmed via high-resolution MRI (HRMRI) that did not meet the Valvassori criterion on high-resolution CT (HRCT) were classified as atypical EVA. Another 21 EVA cases (40 ears) meeting the Valvassori criterion were randomly chosen as typical EVA. The hearing loss (HL), HRCT, and HRMRI findings were compared between the two groups. RESULTS: The difference of HL severity between atypical and typical EVA was not statistically significant (χ2 = 0.12, P > 0.05. The vestibular aqueducts (VA) of atypical EVA cases manifested as borderline dilation (n = 17), focal dilation (n = 3), and normal appearance (n = 6) on the HRCT. The midpoint width of atypical and typical EVA cases wa s 1.06 ± 0.18 mm and 2.10 ± 0.55 mm, respectively, exhibiting a significant difference (t = - 9.20, P < 0.05). In the HRMRI, the degree of dilation and shape of the intraosseous partition of endolymphatic duct and sac (ES) was similar to that of VA on HRCT, while their extraosseous ES was depicted variable slighter dilation compared to that of typical one, the difference between them was statistically significant (t = - 4.10, P < 0.05). CONCLUSION: The HL severity of atypical EVA ears was similar to that of typical ones. Nevertheless, borderline, focal dilation and normal-like appearance of VAs on HRCT and variablely slighter dilation of the extraosseous ES on HRMRI are its characteristic imaging findings.

The role of antibiotics in the surgical management of paediatric obstructive sleep apnoea (OSA): a cohort study

xlomafota13 shared this article with you from Inoreader The role of antibiotics in the surgical management of paediatric obstructive sleep apnoea (OSA): a cohort study Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Mar 9. doi: 10.1007/s00405-021-06720-w. Online ahead of print. ABSTRACT PURPOSE: Obstructive sleep apnoea (OSA) describes an irregular night-time breathing pattern that is present in approximately 1.8% of children and can have a negative impact on quality of life. The use of antibiotics postoperatively is controversial. They are commonly prescribed; however, they can also be associated with side effects and resistance. This study explores the role of antibiotics in the post-operative management of children with OSA in a cohort of children. METHODS: We conducted a retrospective cohort study of children undergoing surgery for OSA or sleep disordered breathing (SDB) at a tertiary paediatric ENT referral centre from November 2018 to November 2019. RESULTS: This study identified 382 children who had undergone surgical treatment for OSA or sleep disordered breathing (SDB); 319 underwent adenotonsil lectomy, 53 adenoidectomy and 10 tonsillectomies. Antibiotics were given post-operatively to 158 (41%) patients and 18 (11%) of these patients presented to hospital with post-operative complications. A higher number of patients re-presented to hospital from the group who did not receive antibiotics (p = 0.982). Bleeding (p = 0.886) and infection (p = 0.823) were also more common in those children who did not receive antibiotics. CONCLUSION: Antibiotics led to fewer complications and re-presentations to hospital in children undergoing operative management of OSA; however, this trend was not found to be statistically significant.

Clinical high-resolution imaging and grading of endolymphatic hydrops in Hydropic Ear Disease at 1.5 T using the two-slice grading for vestibular endolymphatic hydrops in less than 10 min

xlomafota13 shared this article with you from Inoreader Clinical high-resolution imaging and grading of endolymphatic hydrops in Hydropic Ear Disease at 1.5 T using the two-slice grading for vestibular endolymphatic hydrops in less than 10 min Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Mar 9. doi: 10.1007/s00405-021-06731-7. Online ahead of print. ABSTRACT BACKGROUND: Hydropic Ear Disease (Menière) is one of the most common inner ear disorders and one of the most common causes of vertigo attacks. The underlying pathology is a distension of the endolymphatic space of the inner ear, termed endolymphatic hydrops. However, the unequivocal morphologic confirmation of ELH has been restricted to post-mortem histologic analysis until 2007, when the first clinical MR imaging report demonstrated ELH in living patients with Menière's disease at 3 T combined with intratympanic application of contrast. Imaging techniques have since then evolved further. However, a high magnetic field strength of 3 T has consistently been mandatory for reliable clinical imaging of ELH. This limitation has significantly prevented ELH imaging from being widely available across different health care systems around th e world. With the aim of filling this gap, in the present study, we aim to describe the feasibility of ELH imaging at 1.5 T in clinical practice and to develop a dedicated grading system for cochlear and vestibular ELH for MR imaging at 1.5 T. METHODS: In this retrospective study, we examined 30 patients with suspected hydropic ear disease undergoing diagnostic MR imaging. Contrast agent was diluted eightfold in saline solution and unilaterally applied by intratympanic injection as described previously. MRI scanning was performed using a 16-channel head coil on a 1.5 T Achieva Philips Medical Systems Scanner using a 3D FLAIR sequence. For the cochlea, a 3-stage grading was developed. For the vestibulum, a 4-stage grading based on two axial slices was developed by analysing both the superior and the inferior part of the vestibulum. The presence of hydropic herniation of the endolymphatic space into the posterior crus of the horizontal semicircular canal was evaluated. RES ULTS: In all 30 patients, the perilymphatic fluid spaces of the inner ear showed clear and high signal intensity, while the endolymphatic space was not enhanced. In all patients, the vestibular endolymphatic space could be clearly delineated and differentiated from the perilymphatic space. Analysis of the cochlear endolymphatic space revealed no evidence of ELH in 7 patients, a grade 1 cochlear ELH in 11 patients and a grade 2 cochlear ELH in 12 patients. Analysis of the vestibular endoylmphatic space revealed no evidence of ELH in 8 patients, a grade 1 vestibular ELH in 5 patients, a grade 2 vestibular ELH in 9 patients and a grade 3 vestibular ELH in 8 patients. Three patients showed a clear hydropic herniation of the vestibular endolymphatic space into the posterior non-ampullated crus of the horizontal SCC. CONCLUSION: In summary, the findings presented in this study offer an easy, reliable and universally available technique of ELH imaging for diagnostic management of pat ients with suspected Hydropic Ear Disease.

Clinical and videofluoroscopic outcomes of laparoscopic treatment for sliding hiatal hernia and associated gastroesophageal reflux in brachycephalic dogs

xlomafota13 shared this article with you from Inoreader Clinical and videofluoroscopic outcomes of laparoscopic treatment for sliding hiatal hernia and associated gastroesophageal reflux in brachycephalic dogs Via swallowing exercises Vet Surg. 2021 Mar 9. doi: 10.1111/vsu.13622. Online ahead of print. ABSTRACT OBJECTIVE: To describe a laparoscopic technique for treatment of sliding hiatal hernia (SHH) and associated gastroesophageal reflux (GER) in brachycephalic dogs and document clinical and videofluoroscopic outcomes postoperatively. STUDY DESIGN: Prospective clinical trial. ANIMALS: Eighteen client-owned dogs. METHODS: A three-port laparoscopic approach was used. Intracorporeal suturing wa s used for hiatal plication and esophagopexy, and left-sided laparoscopic or laparoscopic-assisted gastropexy was performed. A standardized canine dysphagia assessment tool (CDAT) questionnaire was completed by owners pre- and postoperatively. Videofluoroscopic swallow studies (VFSS) were used to evaluate esophageal function, and impedance planimetry was used to assess lower esophageal sphincter geometry preoperatively and in a subset of dogs postoperatively. RESULTS: Median age was 27.5 (range 5-84) months. Conversion to open surgery was necessary in 1 (5.5%) of 18 dogs. Regurgitation after eating, and associated with activity/exercise, improved significantly when comparing pre- and postoperative CDAT assessments. Hiatal hernia and GER severity scores improved significantly between pre- and postoperative VFSS assessments, whereas SHH and GER frequency scores did not. One dog developed pneumothorax intraoperatively, underwent cardiopulmonary arrest, and died. Minor complicatio ns included splenic (n = 6) and hepatic lacerations (n = 3) that did not require specific therapy. CONCLUSION: A laparoscopic approach to treatment of SHH and GER led to improvements in clinical and VFSS indices in the majority of brachycephalic dogs. However, a subset of dogs still demonstrated some clinical signs postoperatively. CLINICAL RELEVANCE: In experienced hands, laparoscopic treatment of SHH and GER offers a minimally invasive alternative to open surgery.

Use of Radiofrequency Technology in Endonasal Skull Base and Transcranial Procedures

xlomafota13 shared this article with you from Inoreader Use of Radiofrequency Technology in Endonasal Skull Base and Transcranial Procedures Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0040-1721820 Objective Radiofrequency ablation is widely utilized in otorhinolaryngology. It is used for ablation, coagulation and resection, and hemostasis. It causes tissue destruction through a chemical interaction of ions. The potential benefit is to cause less thermal injury to surrounding tissues compared with other coagulative tools. In this article, we present novel uses of radiofrequency ablation in endoscopic endonasal, and transcranial surgery. This is the first study to describe its use in transcranial cases. Design, Setting, and Participants This is a retrospective study of patients between 2016 and 2018 who underwent either endoscopic endonasal or transcranial surgery where radiofrequency ablation was used. Main Outcome Measures We looked at indication for usage, blood loss, postoperative imaging to identify any stroke or edema, and clinical outcomes of these patients. Results The radiofrequency device was used in eight endoscopic endonasal cases and four craniotomies. Four cases were for encephalocele repair and eight were for various intracranial pathologies. In endonasal encephalocele repair, the radiofrequency ablation helped in shrinking the herniated brain while minimizing thermal injury to the surrounding tissue. In tumors resection, the combination of ablation and coagulation effect was particularly effective for highly vascularized tumors. There were no vascular or major neurologic injuries. Postoperative periencephalocele edema was noted in one case. Conclusion Initial experience with radiofrequency ablation showed that it was a safe technique to use in both endonasal skull-base and transcranial procedures. It seemed particularly useful for highly vascularized tumors but a greater experience is needed to further clarify its role in these procedures.

Impact of Type of Treatment Center and Access to Care on Mortality and Survival for Skull Base Chordoma and Chondrosarcoma

xlomafota13 shared this article with you from Inoreader Impact of Type of Treatment Center and Access to Care on Mortality and Survival for Skull Base Chordoma and Chondrosarcoma Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0040-1722228 Background In adults with skull base chordoma or chondrosarcoma, the impact of treatment center and access to care have not been well described in regard to perioperative mortality and survival. Methods A query of the National Cancer Database (NCDB) and review of 1,102 adults—488 with chordomas and 614 with chondrosarcomas—was performed. The Kaplan–Meier's product limit method and chi-square analysis, respectively, assessed overall survival and 30-day (30D) and 90-day (90D) mortalities. Results For 925 patients who had surgery and available mortality data, the 30D and 90D mortality rates were 0.9 and 1.5%. Lower education level (p = 0.0185) and treatment at a nonacademic facility (p = 0.016) were associated with increased risk of 90-day mortality. Median follow-up was 52 months and analysis was dichotomized by histology. For those with skull base chordoma, patients from a larger metro size (p = 0.002), age below the median 52 years (p ≤ 0.001), and private insurance (<0.001) were associated with prolonged survival, whereas for skull base chondrosarcoma, the factors were treatment at an academic medical center (p = 0.001), high-volume center (p = 0.007), age below the median 52 years (p ≤ 0.001), higher income (p = 0.043), higher education (p = 0.017), and private insurance (p ≤ 0.001). Comparing high-, medium-, and low-volume centers, high-volume centers were most likely to be academic, deliver radiotherapy, escalate doses >70 Gy, and utilize proton radiotherapy consistent across both disease subsets. Conclusion Higher educational attainment and treatment at an academic facility were associated with decreased 90D mortality for patients with skull base chordoma and chondrosarcoma. For those with skull base chordoma, larger metro size, younger age, and private insurance were associated with prolonged survival; for those with chondrosarcoma, it was treatment at a high-volume or academic medical center, younger age, higher income or education, and private insurance.

Transmastoid Trautman's Triangle Combined Low Retrosigmoid Approach for Foramen Magnum Meningiomas: Surgical Anatomy and Technical Note

xlomafota13 shared this article with you from Inoreader Transmastoid Trautman's Triangle Combined Low Retrosigmoid Approach for Foramen Magnum Meningiomas: Surgical Anatomy and Technical Note Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0040-1713755 Objective This study was aimed to assess the potential of utilizing a transmastoid Trautman's triangle combined low retrosigmoid approach for ventral and ventrolateral foramen magnum meningiomas (FMMs) surgical treatment. Methods We simulated this transmastoid Trautman's triangle combined low retrosigmoid approach using five adult cadaveric heads to explore the associated anatomy in a step-by-step fashion, taking pictures of key positions as appropriate. We then employed this approach in a single overweight patient with a short neck who was suffering from large ventral FMMs and cerebellar tonsillar herniation. Results Through cadaver studies, we were able to confirm that this transmastoid Trautman's triangle combined with low retrosigmoid approach achieves satisfactory cranial nerve and vasculature visualization while also offering a wide view of the whole of the ventrolateral medulla oblongata. We, additionally, have successfully employed this approach to treat a single patient suffering from large ventral FMMs with cerebellar tonsillar herniation. Conclusion This transmastoid Trautman's triangle combined low retrosigmoid approach may represent a complement to treatment strategies for ventral and ventrolateral FMMs, particularly in patients with the potential for limited surgical positioning due to their being overweight, having a short neck and suffering from cerebellar tonsillar herniation.

Multi-level factors associated with more intensive use of radioactive iodine for low-risk thyroid cancer

xlomafota13 shared this article with you from Inoreader Multi-level factors associated with more intensive use of radioactive iodine for low-risk thyroid cancer Via radioactive iodine J Clin Endocrinol Metab. 2021 Mar 4:dgab139. doi: 10.1210/clinem/dgab139. Online ahead of print. ABSTRACT CONTEXT: The use of radioactive iodine (RAI) for low-risk thyroid cancer is common, and variation in its use exists, despite the lack of benefit for low-risk disease and potential harms and costs. OBJECTIVE: To simultaneously assess patient- and physician-level factors associated with patient-reported receipt of RAI for low-risk thyroid cancer. DESIGN, SETTING, PART ICIPANTS: This population-based survey study of patients with newly-diagnosed differentiated thyroid cancer identified via the Surveillance Epidemiology and End Results (SEER) registries of Georgia and Los Angeles County included 989 patients with low-risk thyroid cancer, linked to 345 of their treating general surgeons, otolaryngologists and endocrinologists. MAIN OUTCOMES: Patient-reported receipt of RAI for low-risk thyroid cancer. RESULTS: Among this sample, 48% of patients reported receiving RAI, and 23% of their physicians reported they would use RAI for low-risk thyroid cancer. Patients were more likely to report receiving RAI if they were treated by a physician who reported they would use RAI for low-risk thyroid cancer compared to those whose physician reported they would not use RAI (Adjusted OR: 1.84, 95%CI: 1.29-2.61). The odds of patients reporting they received RAI was 55% lower among patients whose physicians reported they saw a higher volume of patients w ith thyroid cancer (40+ vs. 0-20) (Adjusted OR: 0.45, 0.30-0.67). CONCLUSIONS: Physician perspectives and attitudes about using RAI, as well as patient volume, influence RAI use for low-risk thyroid cancer. Efforts to reduce overuse of RAI in low-risk thyroid cancer should include interventions targeted towards physicians, in addition to patients.

Diagnostic use of fine‐needle aspiration cytology and core‐needle biopsy in head and neck sarcomas

xlomafota13 shared this article with you from Inoreader Diagnostic use of fine‐needle aspiration cytology and core‐needle biopsy in head and neck sarcomas Via Head & Neck Abstract The diagnostic role of fine‐needle aspiration cytology (FNAC) and core‐needle biopsy (CNB) has not been comprehensively assessed in head and neck sarcomas. A systematic review of published cases (1990–2020) was conducted. Diagnostic performance of both FNAC/CNB to determine tumor dignity and histopathological diagnosis was calculated. One hundred and sixty‐eight cases were included for which FNAC (n = 156), CNB (n = 8), or both (n = 4) were used. Predominant histologies were skeletal muscle, chondrogenic and vascular sarcomas. FNAC correctly assessed dignity in 76.3% and histology in 45% of cases. Dignity was significantly better for vascular tumors, metastatic and recurrent specimens, and worse for chondrogenic sarcomas. CNB showed a 92% accuracy to identify dignity and 83% for histopathology. FNAC and CNB are useful methods for the diagnosis of head and neck sarcomas, particularly well‐suited in the context of recurrent or metastatic disease. The role of CNB remains largely unexplored for this indication. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
