Abstract
Cholesteatoma is a rare and benign disease, but its propensity to cause erosive damage through uninhibited growth can be detrimental to hearing and health. Prior reports indicated a genetic component to pathogenesis in at least a subset of patients. In this study, we aimed to identify rare DNA variants in affected patients. The salivary DNA of six patients whose middle ear tissues were obtained during tympanoplasty/mastoidectomy surgeries were submitted for exome sequencing. Tissue samples from the same patients were previously submitted for mRNA sequencing and analyzed for differentially expressed genes (DEGs). From the generated exome sequence data, rare predicted-to-be-damaging variants were selected within previously identified DEGs, and the candidate genes within which these rare variants lie were used for network analysis. Exome sequencing of six DNA samples yielded 5,078 rare variants with minor allele frequency <.001. A total of 510 variants were predicted to be deleterious and 52 were found to lie within previously identified DEGs. After selecting variants based on quality control measures, 12 variants were identified all from one pediatric patient. Network analysis identified ten significant cellular pathways, including protein transport, viral process, regulation of catalytic activity and cell cycle, and apoptotic and rhythmic processes. We hypothesize that the candidate genes identified in this study may be part of key signaling pathways during the mucosal response to middle ear infection. The occurrence of multiple rare variants may play a role in earlier onset of cholesteatoma formation in chronic otitis media.

Disorders of the eye, ear, skin, and nervous system in women with Turner syndrome -a nationwide cohort study. Eur J Hum Genet 2022; 30:229-236. [PMID: 34707298 PMCID: PMC8821537 DOI: 10.1038/s41431-021-00989-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 09/29/2021] [Accepted: 10/14/2021] [Indexed: 02/03/2023] Open
Abstract
The literature about eye, ear, nose, skin, and nervous system disorders in women with Turner syndrome is equivocal. Impaired vision and hearing in women with Turner syndrome have been described, and case reports of Turner syndrome girls suffering from epilepsy have been published, but no large population-based-studies have explored the occurrence of any of these disorders. We aimed to investigate the risk of admission with disorders related to the eye, ear, nose, skin, and nervous system, compared with background females, and the impact of hormone replacement therapy on these conditions. 1,156 females with TS diagnosed during 1960-2014 were identified using the Danish Cytogenetic Central Registry and linked with personal-level data from the National Patient Registry and the Medication Statistics Registry. Statistics Denmark randomly identified 115,577 age-matched background females. Negative binomial regression was used to analyze hospital discharge diagnoses, reporting incidence rate ratios (IRR). Women with Turner syndrome have an increased risk of developing eye disorders (IRR 4.3 (95% CI 3.5-5.4), including cataract, glaucoma, ocular movement, and accommodation. The risk of ear disorders (IRR 35.0 (27.9-43.9)) and nose (IRR 2.2 (1.4-3.6)) was increased in women with Turner syndrome, due to otitis media, cholesteatoma, and hearing loss. Disorders of the nervous system such as epilepsy were increased IRR 6.2 (2.4-15.9), along with skin conditions IRR 2.2 (95%CI 1.7-2.7) like psoriasis, atopic dermatitis, and ingrown nails.

Abstract
AIM To determine the prevalence and risk factors of ear disease in Turner syndrome (TS), propose an algorithm for future surveillance and recommend preventative strategies. METHODS Review of TS patients seen in the West of Scotland between 1989 and 2015, with questionnaire follow-up in 2015. RESULTS Of 168 girls, median age 27.3 (3.8-47.2) years, ear problems occurred more frequently with 45,X and 45,X/46,XiXq than other karyotypes: 71/103 (69%) versus 23/65 (35%). Recurrent acute otitis media (AOM) first developed at 0-5 years in 23 (40%) girls, persisting in 16 (10%) at 5-10 years; and first developing at 5-10 years in 11 (7%). Persistent otitis media with effusion (OME) first developed at 0-5 and 5-10 years in 23 (40%) and 14 (8%) girls. Recurrent AOM was significantly linked with cholesteatoma in 8 (4.9%) girls (7 aged >10 years). Permanent hearing loss was documented in 28 girls (16.7%), with 16 (9.5%) receiving hearing aids (bone-anchored in 3). CONCLUSION Acute otitis media and OME occur commonly in preschool TS girls and may persist or newly develop in later childhood. Recurrent AOM predisposes to cholesteatoma. Strategies to reduce otological morbidity include: intensive patient education, annual audiology, vaccinations and a randomised trial of antibiotic prophylaxis in high-risk groups.

Abstract
OBJECTIVE To explore the relative frequency of a family history of cholesteatoma in patients with known cholesteatoma, and whether bilateral disease or earlier diagnosis is more likely in those with a family history. Associations between cleft lip or palate and bilateral disease and age of diagnosis were also explored. DESIGN An online survey of patients with diagnosed cholesteatoma was conducted between October 2017 and April 2019. PARTICIPANTS The sample consisted of patients recruited from two UK clinics and self-selected respondents recruited internationally via social media. MAIN OUTCOME MEASURES Side of cholesteatoma, whether respondents had any family history of cholesteatoma, age of diagnosis and personal or family history of cleft lip or palate were recorded. RESULTS Of 857 respondents, 89 (10.4%) reported a positive family history of cholesteatoma. Respondents with a family history of cholesteatoma were more likely to have bilateral cholesteatoma (P = .001, odds ratio (OR) 2.15, 95% confidence interval (CI) 1.35-3.43), but there was no difference in the age of diagnosis (P = .23). Those with a history of cleft lip or palate were not more likely to have bilateral disease (P = .051, OR 2.71, CI 1.00-7.38), and there was no difference in age of diagnosis (P = .11). CONCLUSION The relatively high proportion of respondents that reported a family history of cholesteatoma offers supporting evidence of heritability in cholesteatoma. The use of social media to recruit respondents to this survey means that the results cannot be generalised to other populations with cholesteatoma. Further population-based research is suggested to determine the heritability of cholesteatoma.

Abstract
Turner syndrome is recognized now as a syndrome familiar not only to pediatricians and pediatric specialists, medical geneticists, adult endocrinologists, and cardiologists, but also increasingly to primary care providers, internal medicine specialists, obstetricians, and reproductive medicine specialists. In addition, the care of women with Turner syndrome may involve social services, and various educational and neuropsychologic therapies. This article focuses on the recognition and management of Turner syndrome from adolescents in transition, through adulthood, and into another transition as older women. It can be viewed as an interpretation of recent international guidelines, complementary to those recommendations, and in some instances, an update. An attempt was made to provide an international perspective. Finally, the women and families who live with Turner syndrome and who inspired several sections, are themselves part of the broad readership that may benefit from this review.

X chromosome gene dosage as a determinant of congenital malformations and of age-related comorbidity risk in patients with Turner syndrome, from childhood to early adulthood.

Abstract
Objective Turner Syndrome is associated with several phenotypic conditions associated with a higher risk of subsequent comorbidity. We aimed to evaluate the prevalence of congenital malformations and the occurrence of age-related comorbid conditions and to determine whether the frequencies of congenital and acquired conditions depend on X chromosome gene dosage, as a function of karyotype subgroup. Design and methods This national retrospective observational cohort study includes 1501 patients. We evaluated the prevalence of congenital malformations and the cumulative incidence of subsequent specific comorbidities at five-year intervals, from the ages of 10 to 30 years, with stratification by karyotype subgroup: 45,X (n = 549), 45,X/46,isoXq (n = 280), 46,X,r(X)/46,XX (n = 106), 45,X/46,XX (n = 221), presence of Y (n = 87). Results Median age was 9.4 (3.7-13.7) years at first evaluation and 16.8 (11.2-21.4) years at last evaluation. Congenital heart (18.9%) malformations were more frequent in 45,X patients, and congenital renal (17.2%) malformations were more frequent in 45,X, 45,X/46,isoXq and 46,X,r(X)/46,XX patients than in those with 45,X/46,XX mosaicism or a Y chromosome (P < 0.0001). The cumulative incidence of subsequent acquired conditions, such as thyroid disease, hearing loss, overweight/obesity, dyslipidemia and, to a lesser extent, celiac disease, glucose intolerance/type 2 diabetes, hypertension and liver dysfunction increased with age, but less markedly for patients with mosaicism than for those with other karyotypes. Patients with a ring chromosome were more prone to metabolic disorders. Conclusion These data suggest that X gene chromosome dosage, particularly for Xp genes, contributes to the risk of developing comorbidities.

Abstract
Hearing loss is one of the major medical concerns in girls and women with Turner syndrome (TS) and has a negative effect on well-being and quality of everyday life. Sensorineural hearing loss is the most common type of hearing loss, affecting more than half of adults with TS. Karyotypes with a loss of the short p-arm on the X-chromosome are more prone to ear and hearing problems. The importance of detecting, investigating, and treating hearing loss with hearing aids cannot be emphasized enough. The pathophysiology of the sensorineural hearing loss in TS is not known, but theories regarding estrogen deficiency, the cell cycle delay hypothesis, IGF-1 deficiency and the possible role of the KDM6A gene are discussed. Due to the diversity of symptoms and conditions within the same karyotype, a combination of genetic factors altered by epigenetic and/or hormonal effects is probable. Further research is needed regarding the pathophysiology of ear and hearing problems in TS to develop new treatment methods.

Abstract
Pediatric cholesteatoma occurs in one of two forms: congenital cholesteatoma, developing from embryonic epidermal cell rests or acquired cholesteatoma, associated with a focal defect in the tympanic membrane. This disease has been traditionally managed with the operating microscope, often requiring mastoidectomy for adequate visualization of and access to the middle ear and mastoid cavities. Recently, advances in endoscopic equipment have enabled otologists to manage most cases of pediatric cholesteatoma via a minimally-invasive, transcanal endoscopic approach. This review discusses the current literature relating to the etiopathogenesis, assessment and endoscopic management of pediatric cholesteatoma. Early outcomes of endoscopic treatment, emerging trends and technologies are also reviewed.

Abstract
BACKGROUND AND AIM As in other syndromes characterized by craniofacial anomalies, middle ear cholesteatoma is known to have a high prevalence in Turner syndrome. The aim of this study was to review a multicenter experience with the surgical management of middle ear cholesteatoma in children with Turner syndrome. METHODS We retrospectively analyzed sixteen girls with Turner syndrome who underwent otologic surgery for middle ear cholesteatoma between January 2000 and December 2012. Surgery was performed in 3 tertiary care otologic centers. Four patients had bilateral disease, resulting in a total of 20 ears treated. The following data were recorded: age, history of ventilation tube insertion, status of the controlateral ear, cholesteatoma location and extension, and surgical technique involved. Cholesteatoma recidivism, stable mastoid cavity and hearing levels were the main outcomes measured. RESULTS Follow-up ranged from 3 to 15 years (mean 7 years). Fourteen ears underwent canal wall down mastoidectomy: no cases of recurrent cholesteatoma were observed in these cases; revision mastoidectomy with cavity obliteration was needed in 2 ears (14.3%) for recurrent otorrhea. In the remaining 6 ears a staged canal wall up mastoidectomy was performed: 1 child showed a recurrent cholesteatoma and required conversion to canal wall down mastoidectomy. A postoperative air-bone gap result of 0 to 20 dB was achieved in 6 ears (30%); in 9 ears (45%) postoperative air-bone gap was between 21 and 30 dB, while in 5 (25%) was >30 dB. Bone conduction thresholds remained unaffected in all cases. CONCLUSIONS Cholesteatoma in children with Turner syndrome is a challenging entity for the otologic surgeon. Although not mandatory, canal wall down mastoidectomy should be regarded as the technique of choice to achieve a safe and dry ear in TS children with middle ear cholesteatoma. Intact canal wall mastoidectomy should be adopted only in appropriately selected patients such as those with limited attic cholesteatoma that can be regularly followed-up.

Abstract
The European Academy of Otology and Neurotology in collaboration with the Japanese Otological Society (EAONO/JOS) recently produced a joint consensus document outlining the definitions, classification and staging of middle ear cholesteatoma. The goals were to provide terminologies in the description of cholesteatoma, classify cholesteatoma into distinct categories to facilitate the comparison of surgical outcomes and to provide a staging system that reflects the severity, difficulty of complete removal and restoration of normal function. Cholesteatoma is considered a benign, expanding and destructive epithelial lesion of the temporal bone that is the result of a multifactorial process. If undetected and left treated, cholesteatoma may lead to significant complications including hearing loss, temporal bone destruction and cranial invasion. Recent advances in imaging modalities have allowed for high sensitivity and specificity in identifying the presence of cholesteatoma. Despite these advances, deficiencies exist around the world with access to health care facilities meaning cholesteatoma remains a serious and challenging entity to manage whether found within the pediatric or adult population. Proper diagnosis and management of each form of cholesteatoma is achieved by a thorough understanding of the etiology, classification, clinical presentation and histology, thereby facilitating prevention, early detection and appropriate treatment.
