RESUMO

OBJECTIVE: Due to the coronavirus disease 19 (COVID-19) pandemic, postgraduate training in otorhinolaryngology in 2020 was transferred completely from face-to-face to digital teaching. This paper assesses whether this change was possible without a reduction in the quality of teaching and learning. METHODS: Results of final written examinations were compared for the years 2016-2020, and the results of the teaching evaluation by the students for 2017-2020. The evaluation by students in 2020 included additional questions related to the switch from face-to-face to digital teaching. Additionally, the lecturers and teachers were asked for their assessments. RESULTS: Results of the final written examination did not show any significant differences between 2016-2019 and 2020. Students were highly satisfied with the digital format, but values did not reach the level of former years with face-to-face-teaching. Especially the interaction with patients and the teaching of manual skills were rated lower in the digital format. Lecturers emphasized the additional workload for preparation of digital teaching. CONCLUSION: The results of written examinations showed no difference between digital and face-to-face teaching. Online communication and interaction were reduced and regarded as cumbersome by students and faculty. Digital solutions providing more interaction and active participation are required. The digital format is more appropriate for teaching basic knowledge than for teaching practical skills.

RESUMO

Diseases of the thyroid gland are frequent incidental findings during ultrasound examination of the neck. They affect nearly one third of the normal population. Treatment is not always indicated; however, laboratory diagnostic measures must be initiated to specify the disease. The primary indications for consulting a thyroid specialist are thyroid nodules, goiters, autonomy of the thyroid gland, autoimmune diseases, Graves' disease, and Hashimoto thyroiditis. The aim of this review is to provide an overview of the most important thyroid diseases and their treatment options.

RESUMO

Background: The purpose of our study was to characterize the causes of death among cancer patients as a function of objectives: (i) calendar year, (ii) patient age, and (iii) time after diagnosis. Patients and methods: US death certificate data in Surveillance, Epidemiology, and End Results Stat 8.2.1 were used to categorize cancer patient death as being due to index-cancer, nonindex-cancer, and noncancer cause from 1973 to 2012. In addition, data were characterized with standardized mortality ratios (SMRs), which provide the relative risk of death compared with all persons. Results: The greatest relative decrease in index-cancer death (generally from > 60% to < 30%) was among those with cancers of the testis, kidney, bladder, endometrium, breast, cervix, prostate, ovary, anus, colorectum, melanoma, and lymphoma. Index-cancer deaths were stable (typically >40%) among patients with cancers of the liver, pancreas, esophagus, and lung, and brain. Noncancer causes of death were highest in patients with cancers of the colorectum, bladder, kidney, endometrium, breast, prostate, testis; >40% of deaths from heart disease. The highest SMRs were from nonbacterial infections, particularly among <50-year olds (e.g. SMR >1,000 for lymphomas, P < 0.001). The highest SMRs were typically within the first year after cancer diagnosis (SMRs 10-10,000, P < 0.001). Prostate cancer patients had increasing SMRs from Alzheimer's disease, as did testicular patients from suicide. Conclusion: The risk of death from index- and nonindex-cancers varies widely among primary sites. Risk of noncancer deaths now surpasses that of cancer deaths, particularly for young patients in the year after diagnosis.

RESUMO

BACKGROUND: This was a prospective single-centre, phase I study to document the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), and the recommended phase II dose for future study of capecitabine in combination with radioembolization. METHODS: Patients with advanced unresectable liver-dominant cancer were enrolled in a 3+3 design with escalating doses of capecitabine (375-1000 mg/m(2) b.i.d.) for 14 days every 21 days. Radioembolization with (90)Y-resin microspheres was administered using a sequential lobar approach with two cycles of capecitabine. RESULTS: Twenty-four patients (17 colorectal) were enrolled. The MTD was not reached. Haematologic events were generally mild. Common grade 1/2 non-haematologic toxicities included transient transaminitis/alkaline phosphatase elevation (9 (37.5%) patients), nausea (9 (37.5%)), abdominal pain (7 (29.0%)), fatigue (7 (29.0%)), and hand-foot syndrome or rash/desquamation (7 (29.0%)). One patient experienced a partial gastric antral perforation with a capecitabine dose of 750 mg/m(2). The best response was partial response in four (16.7%) patients, stable disease in 17 (70.8%) and progression in three (12.5%). Median time to progression and overall survival of the metastatic colorectal cancer cohort was 6.4 and 8.1 months, respectively. CONCLUSIONS: This combined modality treatment was generally well tolerated with encouraging clinical activity. Capecitabine 1000 mg/m(2) b.i.d. is recommended for phase II study with sequential lobar radioembolization.

RESUMO

Optimal elective neck treatment in node-negative (cN0) oropharyngeal squamous cell carcinoma (OPSCC) patients is still controversially discussed. Retrospective chart review of 49 cT1-3 cN0 cM0 OPSCC patients, who had undergone surgical resection of the primary and either elective neck dissection (END) (n = 32) or observation (OBS) (n = 17) of the neck was performed. For systematic review of literature, Pubmed and EMBASE were searched for clinical studies including data on both END and OBS of the neck in cN0 OPSCC patients. Estimated 5-year overall survival (OS) rate was 82 % for END and 76 % for OBS [hazard ratio (HR) = 1.01]. Estimated 5-year disease-free survival (DFS) rate was 78 % for END and 67 % for OBS (HR = 1.79); 5-year DSS rate was 97 % (END) and 81 % (OBS) (HR = 2.22). None of the primary outcome variables (OS, DFS, DSS) revealed statistically significant effects for the treatment assignments. Hazard ratios implied an advantage for END. Systematic review of literature yielded only retrospective chart reviews and no data meeting our selection criteria for further data analysis. Due to lack of high-level evidence, the decision for END in cN0 OPSCC remains a diagnostic and therapeutic challenge. The demonstrated clinical equipoise would provide a solid basis for a multicentric, randomized trial.

RESUMO

BACKGROUND: The shortage of medical specialists in Germany has led to increased competition between hospitals, particularly in the recruitment of young skilled doctors. The quality of training appears to be the critical factor in a clinic's recruiting process. At the same time, the suitability of candidates is decreasing. There is currently no data on the suitability of candidates for otorhinolaryngology, nor are there any forecasts about the labor shortage in this speciality. METHODS: We compiled a questionnaire according to accepted guidelines, which was then sent to 160 ENT departments by email. We asked about the size and location of the department and the number of applicants that were suitable or unsuitable. Finally, we asked about the current availability of staff as well as the requirements set by the head physician. RESULTS: The response rate was 34% (54 questionnaires). Departments received an average of 20 applications per year, of which 36% were unsuitable. Departments received more applications in the new German states than in the old; however, no difference in the quality of candidates was seen. University hospitals receive almost three times more applications than other hospitals. The size of the department correlates with the number of applications and quality of the candidates. Almost 60% of chief physicians expected the lack of qualified staff to worsen in the future. However, 40% of chief physicians of large departments (> 50 beds) expected the situation to improve or remain unchanged. Chief physicians' main expectations of candidates included commitment, independent learning and team spirit. CONCLUSIONS: A broad and structured residency program for new employees is the most important factor in the recruitment of new physicians. Large departments and university hospitals have advantages here. The expectations of head physicians differ from those of young staff in terms of commitment and autonomous learning.

RESUMO

BACKGROUND AND PURPOSE: The rate of abnormal intracranial MR imaging findings including subdural collections and dural enhancement after recent lumbar puncture is not known. The purpose of our study was to examine the intracranial MR imaging findings after recent image-guided lumbar puncture. MATERIALS AND METHODS: Patients who underwent contrast-enhanced MR imaging of the brain within 7 days of a CT-guided lumbar puncture between January 2014 and April 2021 were included. Contrast-enhanced MR images were reviewed for diffuse dural enhancement, morphologic findings of brain sag, dural venous sinus distension, and subdural collections. RESULTS: Of the 160 patients who met the inclusion criteria, only 6 patients (3.9%) had new diffuse dural enhancement, though none had dural enhancement when the MR imaging was within 2 days of lumbar puncture. All 6 patients with dural enhancement had small, concurrent subdural collections. Two additional patients had subdural collections, for a total of 5.2% of our population. CONCLUSIONS: Our study is the first to examine intracranial MR imaging after recent lumbar puncture and has 2 key findings: First, 5.2% of patients had small, bilateral subdural collections after recent lumbar puncture, suggesting that asymptomatic subdural collections after recent lumbar puncture are not atypical and do not require further work-up. Additionally, when MR imaging was performed within 2 days of lumbar puncture, none of our patients had diffuse dural enhancement. This argues against the commonly held practice of performing MR imaging before lumbar puncture to avoid findings of dural enhancement, and should not delay diagnostic work-up.

RESUMO

BACKGROUND: Patient satisfaction with surgical outcome is essential in plastic reconstructive surgery, yet no German-language psychometrically validated instrument exist for assessing satisfaction with surgery in the head and neck area. Previously, the short form of the "Frankfurter Selbstkonzeptskalen/FSKN" showed mixed results in a sample of patients undergoing correction of microtia. MATERIAL AND METHODS: This short form was tested in 22 patients following septorhinoplasty and in 24 following tonsillectomy, regarding its psychometric characteristics. RESULTS: While showing good practical characteristics and content validity, there were disappointing results in responsiveness to change and known group's discriminant validity. CONCLUSIONS: Beside sample size, different psychological mechanisms in more common malformations of the head neck area, especially in patients with nasal deformities, have to be further explored as they are not sufficiently represented in the short form of FSKN.

RESUMO

Image-Adapted brachytherapy (IABT) is a modern interdisciplinary development of classic radiation therapy, which allows the application of a high radiation dose while avoiding severe adverse events, thereby improving the prognosis of our patients. Indications in head and neck squamous cell carcinoma (HNSCC) include tumours of the floor of mouth, the face, the paranasal sinuses, the naso- and oropharynx, recurrent cancer and incomplete resections due to close vicinity of the tumor to important structures. The application type can be classified as curative, adjuvant, perioperative as a boost with or without external beam radiation (EBRT) or as a palliative treatment. The published results encourage the integration of IABT as part of the therapy of HNSCC, thereby improving the prognosis and quality of life of our patients.

RESUMO

BACKGROUND: Prognosis of patients with advanced/recurrent cancer of paranasal sinuses and orbit with infiltration of the skull base is very bad. Radical surgery does not improve prognosis. A disadvantage of the radical surgery is the functional loss and the residual cosmetic defect. We present the results of a function-preserving surgery in combination with interstitial, image adapted brachytherapy (IABT) for the treatment of these cancers. METHODS AND PATIENTS: Ten patients with paranasal sinus cancer and 16 patients with sarcomas (n=26) were retrospectively analysed. After a maximum tumor resection (mostly R1-R2 resections), 2-12 flexible afterloading plastic tubes were implanted. The postoperative IABT total dose was 10-25 Gy in 2.5 Gy fractions twice daily fractions for 5 days. RESULTS: In all cases the eye was obtained without functional damage. The IABT was well tolerated. The visual and cosmetic results were satisfactory. Postoperative complications occurred in 7 out of 26 cases without a serious long-term adverse event. Significant radiation-induced complications were found in patients with orbital or skull base involvement. The three years overall survival was 60% for rhabdomyosarcoma, and 33% for the paranasal sinus cancers. CONCLUSIONS: These results show that a combined treatment of function-preserving surgery and a IABT is a feasible, successful and well-tolerated option for curative, salvage and palliative therapy for selected patients with advanced or recurrent carcinoma of the paranasal sinuses and orbit.

RESUMO

BACKGROUND AND PURPOSE: Differentiating between treatment-related lesions and tumor progression remains one of the greatest dilemmas in neuro-oncology. Diffusion MR imaging characteristics may provide useful information to help make this distinction. The aim of the study was to assess the diagnostic accuracy of the centrally reduced diffusion sign for differentiation of treatment-related lesions and true tumor progression in patients with suspected glioma recurrence. MATERIALS AND METHODS: The images of 231 patients who underwent an operation for suspected glioma recurrence were reviewed. Patients with susceptibility artifacts or without central necrosis were excluded. The final diagnosis was established according to histopathology reports. Two neuroradiologists classified the diffusion patterns on preoperative MR imaging as the following: 1) reduced diffusion in the solid component only, 2) reduced diffusion mainly in the solid component, 3) no reduced diffusion, 4) reduced diffusion mainly in the central necrosis, and 5) reduced diffusion in the central necrosis only. Diagnostic accuracy metrics and the area under the receiver operating characteristic curve were estimated for the diffusion patterns. RESULTS: One hundred three patients were included (22 with treatment-related lesions and 81 with tumor progression). The diagnostic accuracy results for the centrally reduced diffusion pattern as a predictor of treatment-related lesions ("mainly central" and "exclusively central" patterns versus all other patterns) were as follows: 64% sensitivity (95% CI, 41%-83%), 84% specificity (95% CI, 74%-91%), 52% positive predictive value (95% CI, 37%-66%), and 89% negative predictive value (95% CI, 83%-94%). CONCLUSIONS: The centrally reduced diffusion sign is associated with the presence of treatment effect. The probability of a histologic diagnosis of a treatment-related lesion is low (11%) in the absence of centrally reduced diffusion.

RESUMO

BACKGROUND AND PURPOSE: Chordoid meningiomas are uncommon WHO grade II primary intracranial neoplasms that possess unique chordoid histology and follow an aggressive clinical course. Our aim was to assess the utility of qualitative MR imaging features and quantitative apparent diffusion coefficient values as distinguishing preoperative MR imaging metrics to identify and differentiate chordoid histology from other meningioma histologic subtypes. MATERIALS AND METHODS: Twenty-one patients with meningiomas with chordoid histology, which included both chordoid meningiomas (>50% chordoid histology) and meningiomas with focal chordoid histology (<50% chordoid histology) with available preoperative MR imaging examinations, including diffusion-weighted imaging, were identified. Qualitative imaging features and quantitative ADC values were compared between meningiomas with chordoid histology and 42 nonchordoid meningiomas (29 WHO grade I, eleven WHO grade II, and 2 WHO grade III). RESULTS: The median ADC (10-3mm2/s) of meningiomas with chordoid histology was significantly higher than nonchordoid meningiomas (1.16 versus 0.92, P < .001), as was the median normalized ADC (1.60 versus 1.19, P < .001). In subgroup analysis, the median and normalized ADC values of chordoid meningiomas (n = 11) were significantly higher than those in meningiomas with focal chordoid histology (n = 10, P < .001 and P < .001, respectively) or nonchordoid meningiomas (n = 42, P < .001 and <0.001, respectively). Median and normalized ADC values were not significantly different between the meningiomas with focal chordoid histology and nonchordoid meningiomas (P = .816 and .301, respectively). Among the qualitative imaging features, only DWI signal intensity was significantly associated with meningiomas with chordoid histology diagnosis. CONCLUSIONS: ADC values are higher in chordoid compared with nonchordoid meningiomas and may be used to discriminate the degree of chordoid histology in meningiomas. While qualitative MR imaging features do not strongly discriminate chordoid from nonchordoid meningiomas, DWI may allow preoperative identification of chordoid meningiomas.

RESUMO

A concept for an ORL residency training program is necessary because of personnel bottlenecks, quality assurance and benchmarkings. We have created a 2.5 years' program, which is based on 6 pillars: 1. Acquisition of the necessary specialist knowledge by the resident in self-study. 2. Weekly attendance of training lectures according to a study timetable, a monthly specialist seminar to discuss case examples. 3. Weekly presentation by the resident on an article from the current literature, alternating with a presentation on cases and a morbidity and mortality conference. 4. Annual 60 min learning target test. 5. Definition of a surgical training calendar oriented to the new national ORL training regulations. 6. Internal operation course with preparative exercises in anatomy and visit to an operations course at a renowned otolaryngology clinic each year. After 2.5 years of the training time a revision course is introduced. In this way a basic training will be guaranteed for all residents, which can be assessed by the annual test. Finally, the construction of a further training curriculum should lead to an improved transparent training, a higher standard of quality and improved staff satisfaction.

RESUMO

UNLABELLED: Nasoalveolar cysts are rare nonodontogenic cysts that develop from the soft tissue in the mucobuccal area of the nasal ala. Their origin is a residuum of the nasolacrimal canal. CLINICAL CASE: A 45-year-old woman had been aware of a painless tumor at the base of the nose and in the region of the left nasal ala for several months. We diagnosed a nasolabial cyst, which was extirpated in toto through a combined transvestibular-transnasal approach.

RESUMO

The gusher phenomenon is a very rare complication that may occur during stapedectomy or cochleostomy. A sudden perilymphatic flow of cerebrospinal fluid can be seen following platinotomy. The cause is an abnormal connection between subarachnoid and perilymphatic spaces due to congenital malformation, leading to an abnormally wide cochlear aqueduct or due to an internal auditory canal fistula. We describe a case of posttraumatic gusher phenomenon after a fracture of the petrous bone.

RESUMO

A multimodal, interdisciplinary approach known as intensity-modified brachytherapy is a promising alternative for patients with advanced head and neck cancer infiltrating the orbita and skull base. An 87-year-old man presented with a recurrence of squamous cell carcinoma of the medial corner of the left eye that had been locally resected and irradiated by external beam radiotherapy multiple times. The cancer was resected with preservation of the eye with close margins, implantation of afterloading catheters, and reconstruction of the defect with a median forehead flap. The patient was irradiated with a total radiation dose of 30 Gy IMBT. After 1 year, there was no evidence of locoregional recurrence. The background of this therapeutic process and analysis of the current literature regarding this interdisciplinary treatment of head and neck cancer infiltrating the orbita and skull base are discussed based on this case report.

RESUMO

Expression profiles of CXC- and CC-chemokines in various forms of tonsillar disease were studied to evaluate whether certain chemokines play a predominant role in a specific subset of tonsillar disease. Total RNA was isolated from 89 biopsies (21 hyperplastic palatine tonsils, 25 adenoids, 16 chronic inflammatory palatine tonsils and 27 chronic inflammatory palatine tonsils with histological prove of acute inflammation), reverse transcribed and subjected to PCR amplifying IL-8, Gro-alpha, eotaxin-1, eotaxin-2, MCP-3, MCP-4 and RANTES. 2% agarose gel electrophoresis revealed a predominance of IL-8 in the chronic inflammatory palatine tonsil group compared to tonsillar hyperplasia. Furthermore, eotaxin-2 was strongly overexpressed in adenoid samples compared to chronic inflammatory specimens. Our data suggest that the majority of diseases related to adenoid formation are mediated via an eotaxin-2 expression, whereas chronic inflammatory tonsillitis is associated with IL-8 upregulation. These data imply that adenoids are related to a Th-2, and chronic inflammatory tonsillitis to a Th-1 based immune response.

RESUMO

BACKGROUND AND PURPOSE: The 2016 World Health Organization Classification of Tumors of the Central Nervous System includes "diffuse midline glioma with histone H3 K27M mutation" as a new diagnostic entity. We describe the MR imaging characteristics of this new tumor entity in pediatric patients. MATERIALS AND METHODS: We retrospectively reviewed imaging features of pediatric patients with midline gliomas with or without the histone H3 K27 mutation. We evaluated the imaging features of these tumors on the basis of location, enhancement pattern, and necrosis. RESULTS: Among 33 patients with diffuse midline gliomas, histone H3 K27M mutation was present in 24 patients (72.7%) and absent in 9 (27.3%). Of the tumors, 27.3% (n = 9) were located in the thalamus; 42.4% (n = 14), in the pons; 15% (n = 5), within the vermis/fourth ventricle; and 6% (n = 2), in the spinal cord. The radiographic features of diffuse midline gliomas with histone H3 K27M mutation were highly variable, ranging from expansile masses without enhancement or necrosis with large areas of surrounding infiltrative growth to peripherally enhancing masses with central necrosis with significant mass effect but little surrounding T2/FLAIR hyperintensity. When we compared diffuse midline gliomas on the basis of the presence or absence of histone H3 K27M mutation, there was no significant correlation between enhancement or border characteristics, infiltrative appearance, or presence of edema. CONCLUSIONS: We describe, for the first time, the MR imaging features of pediatric diffuse midline gliomas with histone H3 K27M mutation. Similar to the heterogeneous histologic features among these tumors, they also have a diverse imaging appearance without distinguishing features from histone H3 wildtype diffuse gliomas.

RESUMO

BACKGROUND AND PURPOSE: Cerebral edema associated with brain tumors is an important source of morbidity. Its type depends largely on the capillary ultra-structures of the histopathologic subtype of underlying brain tumor. The purpose of our study was to differentiate vasogenic edema associated with brain metastases and infiltrative edema related to diffuse gliomas using quantitative 3D T1 rho (T1ρ) imaging. MATERIALS AND METHODS: Preoperative MR examination including whole brain 3D T1ρ imaging was performed in 23 patients with newly diagnosed brain tumors (9 with metastasis, 8 with lower grade glioma, LGG, 6 with glioblastoma, GBM). Mean T1ρ values were measured in regions of peritumoral non-enhancing T2 signal hyperintensity, excluding both enhancing and necrotic or cystic component, and normal-appearing white matter. RESULTS: Mean T1ρ values were significantly elevated in the vasogenic edema surrounding intracranial metastases when compared to the infiltrative edema associated with either LGG or GBM (p=0.02 and <0.01, respectively). No significant difference was noted between T1ρ values of infiltrative edema between LGG and GBM (p=0.84 and 0.96, respectively). CONCLUSION: Our study demonstrates the feasibility and potential diagnostic role of T1ρ in the quantitative differentiation between edema related to intracranial metastases and gliomas and as a potentially complementary tool to standard MR techniques in further characterizing pathophysiology of vasogenic and infiltrative edema.

RESUMO

BACKGROUND AND PURPOSE: After the failure of first-line treatment, the clinical prognosis in head and neck cancer (HNSCC) deteriorates. Effective therapeutic strategies are limited due to the toxicity of previous treatments and the diminished tolerance of surrounding normal tissue. This study demonstrates a promising second-line regimen, with function preserving surgical tumor debulking, followed by a combination of postoperative interstitial brachytherapy and a simultaneous protocol of cetuximab and taxol. PATIENTS AND METHODS: From January 2006 to May 2013, 197 patients with HNSCC were treated with brachytherapy at the University Hospital Schleswig-Holstein Campus Lübeck, including 94 patients due to recurrent cancer. Within these, 18 patients were referred to our clinic because of early progressive disease following first- or second-line treatment failure. They received the new palliative regimen. A matched-pair analysis including recurrent tumor stage, status of resection margins, tissue invasion and previous therapy was performed to evaluate this treatment retrospectively. Overall survival (OS), disease-free survival (DFS), functional outcome and treatment toxicity was analyzed on the basis of medical records and follow-up data. RESULTS: DFS and OS of the study group were 8.7 and 14.8 months. Whereas, DFS and OS of the control group, treated only by function preserving tumor debulking and brachytherapy, was 3.9 and 6.1 months respectively. This demonstrates a positive trend through the additional use of the cetuximab-taxane protocol. Furthermore, no increase of therapy induced toxicities was displayed. CONCLUSION: Pre-treated patients with a further relapse benefit from the 'cetuximab-taxane recurrency scheme'. It seems to be a valuable complement to interdisciplinary and multimodal tumor therapy, which improves OS and results in acceptable toxicity.
