Otorhinolaryngology Manifestations of Systemic Illness.

Ear-nose-throat (ENT) manifestations are among the most frequently observed clinical features of systemic illnesses. The patients often present with overt findings of head and neck lesions such as salivary gland swelling or lymphadenopathy. In contrast, patients may present with covert findings of auditory, nasal, and laryngeal symptoms that are less obvious and are often overlooked. Therefore, clinicians should have a high index of suspicion to identify the underlying disease. Early recognition and prompt treatment or referral to specialists may prevent morbidity and mortality. This article discusses various systemic illnesses with ENT manifestations that are commonly encountered.

THE "-OMAS" and "-OPIAS": Targeted and Philosophical Considerations Regarding Hamartomas, Choristomas, Teratomas, Ectopias, and Heterotopias in Pediatric Otorhinolaryngologic Pathology.

The spectrum of "developmental" lesions that occur in the head and neck predominantly congenital in origin and arising at birth and/or discovered in childhood is broad and fascinating. These have been grouped into categories such as "ectopias", "heterotopias", "hamartomas", and "choristomas". On a philosophical and consequently systematic level, these lesions, mostly benign tumors seem to lack a true understanding of the pathogenetic foundation on which to base a more unified taxonomic designation. In this review, we will consider some of these select tumors as they represent syndromic associations (nasal chondromesenchymal hamartoma and DICER1 syndrome), the lingual choristoma from the perspective of its nomenclature and classification, lesions with ectopic meningothelial elements, and teratomas and the enigmatic "hairy polyp" in reference to a broader discussion of pathogenesis and pluripotent cells in the head and neck. A consistent thread will be how these lesions are designated with some final thoughts on future directions regarding the investigation of their pathogenesis and taxonomic nomenclature.

Tertiary Lymphoid Organs: A Primer for Otolaryngologists.

OBJECTIVES/HYPOTHESIS: Lymphoid neogenesis or the development of organised, de novo lymphoid structures has been described increasingly in chronically inflamed tissues. The presence of tertiary lymphoid organs (TLOs) has already been demonstrated to result in significant consequences for disease pathology, severity, prognosis and patient outcomes. Whilst the wider medical community has embraced TLOs as important markers of disease and potential therapeutic targets, the otolaryngology field has only begun turning to these entities in an academic capacity. This review aims to outline the role of tertiary lymphoid organs in disease and summarise key early findings in the ENT field. We also an overview of TLOs, their developmental process and clinicopathological implications. STUDY DESIGN: Literature review. METHODS: A literature search for all relevant peer-reviewed publications pertaining to TLOs and ENT diseases. Search was conducted using PubMed, Embase and CINAHL databases. RESULTS: A total of 24 studies were identified relevant to the topic. The majority of TLO research in ENT fell into the areas of oral squamous cell carcinoma (SCC) and chronic rhinosinusitis (CRS). CONCLUSIONS: Early research into both oral SCC and CRS suggests that TLOs have significant roles within ear, nose and throat (ENT) diseases. At this point in time, however, TLOs remain somewhat a mystery amongst otolaryngologists. As information in this field increases, we may develop a better understanding of how lymphoid neogenesis can influence disease outcomes amongst our patients and, ultimately, how they can be utilised in an immunotherapeutic manner.

30-day unplanned readmission rate in otolaryngology patients: A population-based study in Thuringia, Germany.

PURPOSE: Analyze associations between patients' characteristics and treatment factors with 30-day unplanned readmissions in hospitalized otolaryngology patients in the German Diagnosis Related Group (D-DRG) system. METHODS: A retrospective cohort study was performed on 15.271 otolaryngology admissions of 12.859 patients in 2015 in Thuringia, Germany. The medical records of the 1173 cases (7.6%) with readmission within 30-days were analyzed in detail. RESULTS: The 30-day readmission was planned in 747 cases (4.9%) and was unplanned in 422 cases (2.8%). The median interval between primary and next inpatient treatment was 11 days. The principal diagnosis was the same as during the primary index treatment in 72% of the cases. The most frequent reasons for readmission were: Need for non-surgical therapy (31.2%), need for further surgery (26.3%), post-surgical complaints (16.9%), and recurrence of primary complaints (10.7%). The multivariate analysis revealed that discharge due to patient's request against medical advice was a strong independent factor with high risk for unplanned readmission (Odds Ratio [OR] = 9.62]; confidence interval [CI] = 2.69-34.48). Surgery at index admission (OR = 3.33; CI = 1.86-5.96) was the second important independent risk factor for unplanned readmission. Unplanned readmission had more frequently a non-surgical treatment at readmission than a surgical treatment (OR = 3.92; CI = 2.24-6.84) and needed more frequently further diagnostics (OR = 2.34; CI = 1.34-4.11). The following index International Classification of Diseases (ICD) categories had the highest risk for unplanned readmission: Injury, poisoning and certain other consequences of external causes, ICD: S00-T98 (OR = 66.67; CI = 15.87-333.33), symptoms, signs, abnormal findings, ill-defined causes, not otherwise classified, ICD: R00-R99 (OR = 62.5; CI = 11.76-333.33), blood forming organ diseases, ICD: D50-D90 (OR = 21.276; CI = 3.508-125), and eye/ ear diseases, ICD: H00-H95 (OR = 12.66; CI = 4.29-37.03). CONCLUSIONS: The causes of unplanned 30-day readmission in German otolaryngology inpatients are multifactorial. Specific patient and treatment characteristics were identified to be targeted with health care interventions to decrease unplanned readmissions.

Amyloidosis of the Upper Aerodigestive Tract: Management of a Rare Disease and Review of the Literature.

Amyloidosis in the upper aerodigestive tract is a very rare disease with mainly case reports documented so far. In the pathogenesis, amyloid protein fibers are deposited in organs and tissue. In the upper aerodigestive tract, mostly localized amyloidosis occurs with unspecific symptoms, e.g., dysphagia. We conducted a retrospective multicenter study with two study centers in Germany (tertiary referral hospitals), the University Hospital of Bonn and the University Hospital of Goettingen. For a period of the last 7 years, data were analyzed and patients were recruited consecutively. 14 cases were included to the study. The most common manifestation was in the larynx (n = 11); in one case each localized amyloidosis was found in the tongue, trachea and in the pharynx. Since the majority of our cases (n = 13; 92.6%) presented with unspecific symptoms, biopsy results confirmed the diagnosis of localized amyloidosis. Resection of the lesion was only performed in patients reporting of symptoms, in asymptomatic patients only a non-invasive biopsy was done. In two patients (14.2%), in addition to the focal lesion a systemic amyloidosis was found. Amyloidosis in the upper aerodigestive tract is a rare disease. Nonetheless, every otorhinolaryngologist should be aware of this disease. When detected it is a straight forward to treat illness. The appearance of a systemic amyloidosis needs to be ruled out; thus, there is a chance to develop a multiple myeloma. Given the slow progressive character of amyloidosis, a long-term follow-up up to 10 years is inevitable.

[Epithelial dysfunction associated with pyo-inflammatory diseases of the ENT organs]. / Épitelial'naia disfunktsiia pri gnoino-vospalitel'nykh zabolevaniiakh LOR-organov.

The modern concept of epithelial-endothelial dysfunction and epithelial-endothelial distress-syndrome associated with pyo-inflammatory ENT diseases is presented. It has provided a basis for the analysis of the initial stages of etiopathogenesis of acute and chronic inflammation in the ENT system including the mucous and associated lymphoid tissues as well as the Pirogov-Waldeyer limphopharyngeal ring making up the first protective barrier. The leading role of dysbiosis of synanthropic microflora and endotoxins of the Gram-negative bacteria in the mechanisms of regional responsiveness of the organism to the infection and chronic endotoxic aggression is demonstrated. The regional and synthetic mechanisms underlying the interaction between the external and internal media of the organism are subjected to the analysis with special reference to those operating in epithelium. The possible variants of the outcome of these processes are considered including both the recovery and the development of chronic inflammation. It has been proved that the exhaustion of the internal reserves for the stabilization of the epithelium-associated lymphoid tissue system including the Pirogov-Waldeyer limphopharyngeal ring leads to the formation of epithelial dysfunction as the initial stage of epithelial-endothelial dysfunction and epithelial-endothelial distress-syndrome. It is concluded that the modern concept of epithelial-endothelial dysfunction and epithelial-endothelial distress-syndrome is a fundamental interdisciplinary phenomenon.

[Castleman's Disease - A Case Series of a Rare Lymphoproliferative Disease]. / Morbus Castleman ­ eine harmlose Differenzialdiagnose einer Lymphadenitis colli? ­ Eine Fallserie.

Castleman's disease is a very rare and potentially severe lymphoproliferative disorder. First sign may be cervical lymphadenitis, requiring sufficient support in diagnosis and therapy by an ENT specialist. Based on a case series the current manuscript gives an overview of the symptoms, the course of disease and the therapy options. Patients with the first diagnosis of a Castleman's disease at the ENT clinic of Ulm University during the years 2011-2015 were included. The duration of symptoms, the applied diagnostic and therapeutic algorithms were evaluated. The duration of the rather weak symptoms was inhomogenous and lasted from 14 days to 14 years. After diagnostic exstirpation a hyaline-vascular type of Castelman's disease was confirmed in all cases. One of the 5 cases proved a multicentric type with an additional axillary manifestation, the others were monocentric. In all patients the diagnostic exstirpation was sufficient for therapy without need for adjuvant medication. At the time of publication all patients are in remission for at least 18 resp. 61 months. The ENT specialist encounters Castleman's disease mostly as a long-lasting swelling of cervical lymph nodes refractory to therapy and without severe concomittant symptoms. Due to potentially unfavorable outcomes a timely diagnostic lymph node exstirpation under general anesthesia is indicated. In most cases this surgical intervention represents the sufficient therapy.

Posttransplant Lymphoproliferative Disorder: Otolaryngological Manifestations and Management.

Objective Posttransplant lymphoproliferative disorder (PTLD) is a unifying term for a spectrum of lymphoid expansion entities brought about by immunosuppression and is strongly associated with Epstein-Barr virus (EBV). Otolaryngological findings tend to present early in the clinical course; therefore, disease awareness among otolaryngologists is of utmost importance. This review synthesizes the body of literature pertaining to PTLD involving the head and neck, summarizes contemporary management, and highlights areas for future research. Data Sources PubMed/Medline. Review Methods Primary literature search of the Medline database was performed for all titles published in the past 10 years pertaining to PTLD. The database search included PTLD combined with a collection of otolaryngological MeSH terms. Full manuscripts were reviewed based on relevance of their title and abstract. Selection into this review was according to clinical and scientific relevance. Conclusion Adenotonsillar focus is common in children in whom adenotonsillectomy may be diagnostic and prevents potentially morbid airway obstruction. Sinonasal PTLD may mimic fungal infection. Laryngotracheal involvement predominately presents in children with symptoms of airway obstruction. PTLD limited to the esophagus is rare. Oral PTLD is rare and phenotypically varied. Cutaneous presentation of PTLD is infrequent, yet one-third of cases affects the head and neck. PTLD may present as cervical lymphadenopathy. Implications for Practice PTLD consideration is vital when evaluating posttransplant patients. Children and EBV-seronegative patients should receive otolaryngological follow-up after transplant. PTLD treatment is multidisciplinary and typically led by lymphoma specialists. Formal partnerships between otolaryngologists and transplant centers may improve patient care and research quality.

Systematic review and meta-analysis of venous thromboembolism in otolaryngology-head and neck surgery.

BACKGROUND: The purpose of this study was to present our systematic review and meta-analysis of the data on venous thromboembolism (VTE; deep venous thrombosis [DVT] and/or pulmonary embolism [PE]) in otolaryngology-head and neck surgery (OHNS). METHODS: PubMed and Scopus databases were searched for studies reporting VTE in OHNS. Incidence of VTE and bleeding is reported and meta-analyzed overall and for chemoprophylaxis and squamous cell carcinoma (SCC)/free flap subgroups. RESULTS: A total of 23 studies were included with a total of 618,264 patients. Incidence of VTE was 0.4%. The incidence of bleeding complications was 0.9%. The addition of chemoprophylaxis did not result in a decreased VTE incidence (odds ratio [OR], 0.86), but produced an increased risk of bleeding (OR, 3.78). The overall OR for VTE in SCC/free flap cases was 6.28. CONCLUSION: Chemoprophylaxis may not be necessary in the OHNS non-SCC or free flap patient population and must be balanced against an increased risk of bleeding. © 2017 Wiley Periodicals, Inc.

Transoral robotic surgery for the pediatric head and neck surgeries.

Pediatric robotic surgery is a relatively new technology that has been shown to be safe and feasible for a number of pediatric procedures. Our literature analysis was performed using Pubmed database between January 2005 and December 2015, using key words: "robotic," "robotic surgery," "TORS," "pediatric," "children," "head and neck," and "da Vinci". We selected only publications in English. Eight published reports met the selection criteria. We totally found 41 patients, and the age range was between 2 months and 19 years. The cases are 16 only lingual tonsillectomy, nine base of tongue and lingual tonsillectomy, two malignant disease in the oropharynx (high-grade undifferentiated sarcoma and biphasic synovial sarcoma), one tongue base thyroglossal duct cyst, 11 laryngeal cleft cyst, one posterior glottic stenosis, and one congenital true vocal cord paralysis surgeries. One intraoperative complication was reported. No patient needed postoperative tracheotomy. Hospital duration time had a range of 1-16 days. TORS is new for pediatric patients in head and neck areas, and there were few reports. It is becoming increasingly used in head and neck surgeries and those reports above are encouraging for pediatric robotic airway surgeries in otolaryngology in the future.

[Radiosensitivity and/or radioresistance of head and neck cancers: Biological angle]. / Radiosensibilité et/ou résistance des cancers ORL: aspects biologiques.

Radiation therapy is a cornerstone of head and neck cancer management. Technological improvements in recent years in radiation therapy, with intensity-modulated techniques, reinforce even more its role. However, both local and locoregional relapses are still observed. Understanding biological mechanisms of treatment resistance is a topic of major interest. From the cancer cell itself, its ability to repair and proliferate, its microenvironment and oxygenation conditions, migratory and invasive capacity, to biological parameters related to the patient, there are many mechanisms involving radiosensitivity and/or radioresistance of head and neck cancer. The present study explores the main biological mechanisms involved in radiation resistance of head and neck cancer, and describes promising therapeutic approaches.

Use of the Teres Major Muscle in Chimeric Subscapular System Free Flaps for Head and Neck Reconstruction.

IMPORTANCE: We present what we believe to be the first case series in which the teres major muscle is used as a free flap in head and neck reconstruction. OBJECTIVES: To describe our experience with the teres major muscle in free flap reconstruction of head and neck defects and to identify advantages of this approach. DESIGN, SETTING, AND PARTICIPANTS: A retrospective review was performed at 2 tertiary care centers between February 1, 2007, and June 30, 2012. Data analysis was conducted from July 31, 2014, through December 1, 2014. INTERVENTION: Teres major muscle free flap for use in head and neck reconstruction. MAIN OUTCOMES AND MEASURES: Indications for use, complications, and outcomes including donor site morbidity. RESULTS: The teres major free flap was used in 11 patients as a component of chimeric subscapular system free flaps for a variety of complex head and neck defects. The teres major muscle was used to fill soft-tissue defects of the neck, face, and nasal cavity; it provided substantial soft-tissue volume but was less bulky than the latissimus dorsi muscle. The teres major muscle was also used to provide protection for vascular anastomoses and/or great vessels and to enhance soft-tissue coverage of the mandibular reconstruction plate. In addition, the muscle was selected as a substrate for skin grafting where inadequate neck skin remained. Flap survival occurred in 10 of 11 flaps (91%). Two flaps (18%) demonstrated venous congestion that was managed successfully. Two patients (18%) developed minor recipient-site complications (submental fistula and infection with recurrent wound dehiscence and plate exposure). All donor sites healed well, with chronic, mild shoulder pain noted in 2 patients (18%) and no postoperative seromas observed in any patient. CONCLUSIONS AND RELEVANCE: Addition of the teres major muscle to a subscapular system free flap is an option for reconstruction of a variety of complex head and neck defects, particularly when a moderate amount of soft tissue is required. In select cases, the teres major muscle may have advantages over the latissimus dorsi muscle.

Untreated head and neck surgical disease in Sierra Leone: a cross-sectional, countrywide survey.

OBJECTIVES: Demonstrate how the Surgeons OverSeas Assessment of Surgical Need (SOSAS) can be used to determine the burden of head and neck (H&N) surgical disease in developing countries and identify reasons for untreated disease. STUDY DESIGN: Cluster randomized, cross-sectional, countrywide survey. SETTING: Sierra Leone. SUBJECTS AND METHODS: The survey was administered to 75 of 9671 enumeration areas in Sierra Leone between January 9 and February 3, 2012, with 25 households in each cluster randomly selected for the survey. A household representative and 2 randomly selected household members were interviewed. Need for surgical care was based on participants' responses to whether they had an H&N condition that they believed needed surgical care. RESULTS: Of 1875 households, data were analyzed for 1843 (98%), with 3645 total respondents. Seven hundred and one H&N surgical conditions were reported as occurring during the lifetime of the 3645 respondents (19.2%).The current prevalence of H&N conditions in need of a surgical consultation was 11.8%. No money (60.1%) was the most common reason respondents reported for not receiving medical care. A bivariate analysis demonstrated that age, village type, education, and type of condition may be predictors for seeking health care and/or receiving surgical care. CONCLUSIONS: These results show limited access for patients to be evaluated for a potential H&N surgical condition in Sierra Leone. The true incidence of untreated surgical disease is unknown as most respondents were not evaluated by a surgeon. This survey could be used in other countries as health care professionals assess surgical needs throughout the world.
