Presença de cerume impactado em deficientes mentais: análise de 400 pacientes / Presence of cerumen impaction in inttellectually disabled persons: analysis of 400 cases

Introdução: Cerume impactado pode causar sintomas como zumbidos, tontura, plenitude auricular e hipoacusia. Estima-se que de 2% a 6% da população adulta apresente cerume impactado ou em excesso, sendo maior a incidência em pacientes com deficiência mental. Este estudo visa avaliar a incidência de cerume impactado em 400 indivíduos com deficiência mental. Métodos: estudo de coorte, longitudinal e prospectivo. Fizeram parte desse estudo 400 pacientes com idade entre 13 e 51 anos, com diagnóstico de deficiência mental, associada ou não à deficiência física; considerando sexo, idade, grau de deficiência mental, deficiência física, presença de cerume e associação com alterações do meato acústico externo como otite externa aguda. Resultados: a presença de cerume impactado em orelha esquerda foi encontrada em 33,0% da amostra e em 32,75% em orelha direita. Em 31% dos indivíduos encontrou-se deficiência física e a paralisia espástica foi a de maior incidência (15,5%). Em relação ao grau de deficiência mental, a grave foi a mais incidente (41,5%). Entre os 165 pacientes com cerume impactado na orelha direita, 25,5% tinha deficiência física e 7,5% com otite externa aguda; e entre os 161 pacientes com cerume impactado na orelha esquerda, 27,3% e otite externa aguda em 8,25%. Conclusão: os indivíduos com deficiência mental possuem uma incidência de cerume impactado significativamente maior. Em ambas as orelhas, notou-se que quanto maior o grau de deficiência mental, maior a chance de cerume impactado e otite externa aguda.

Introduction: cerumen impaction can cause symptoms such as tinnitus, dizziness, ear fullness and hearing loss. It is estimated that from 2% to 6% of the adult population has impacted or excess cerumen, with a higher incidence in patients with mental deficiency. Objective: this study aims to evaluate the incidence of impaction cerumen in 400 individuals with mental disabilities. Methods: longitudinal and prospective cohort study. This study included 400 patients aged 13 to 51 years, with a diagnosis of mental disability, associated or not with physical disability; considering gender, age, degree of mental deficiency, physical disability, presence of earwax and association with external auditory canal alterations such as acute external otitis. Results: the presence of impacted earwax in the left ear was found in 33.0% of the sample and in 32.75% in the right ear. In 31% of the individuals found physical disability, spastic paralysis was the one with the highest incidence (15.5%). In relation to the degree of mental deficiency, the severe one was the most incident (41.5%). Among the 165 patients with impacted earwax in the right ear, 25.5% had physical disability and 7.5% had acute external otitis; and among the 161 patients with impacted earwax in the left ear, 27.3% and acute external otitis in 8.25%. Conclusion: mentally handicapped individuals have a significantly higher impact incidence of cerumen than the population. In both ears, it was noted that the higher the degree of mental deficiency, the greater the chance of impacted earwax and acute external otitis.

Substance P and Calcitonin Gene-Related Peptide in the Glands of External Auditory Canal Skin

OBJECTIVES: The earwax (cerumen) that covers external auditory canal (EAC) skin contains a mixture of ceruminous and sebaceous gland substances, such as lipids, peptides, and proteins. The components secreted from the ceruminous gland that is a modified sweat gland form cerumen and contain several antimicrobial factors. Since substance P (SP) and calcitonin gene-related peptide (CGRP), known as a secretagogue, have been found in sweat glands, our purpose was to determine the expression of SP and CGRP in the glands of EAC skin. METHODS: Sections of normal human EAC skins were immunostained for the presence of SP and CGRP using polyclonal antibodies. Immunoreactivity was detected using an avidin-biotin peroxidase complex method. RESULTS: SP staining was found in ceruminous gland acini and myoepithelial cells. But the SP staining was not found in the sebaceous glands and epidermal region. CGRP was strongly stained in the ceruminous gland and weakly in the sebaceous gland cells. Interestingly, most prominent staining of SP and CGRP was noted in the myoepithelial cells of the ceruminous gland. CONCLUSION: The findings in this study suggest that SP and CGRP are expressed in the glands of the EAC skin and secreted in the process of ceruminous gland secretion.

Does Hearing Aid Use Increase the Likelihood of Cerumen Impaction?

BACKGROUND AND OBJECTIVES: Impacted cerumen is a common condition in adults. It is commonly believed that wearing hearing aids may increase the cerumen impaction, although no empirical evidence exist. The current study was aimed at studying if the use of hearing aids increase the likelihood of impaction of cerumen. SUBJECTS AND METHODS: The study used retrospective design. The study sample included 164 consecutive patients who were referred to cerumen clinic from Royal Glamorgan Hospital, Wales. Audiologist classified the cerumen impaction into four categories (i.e., no cerumen; non-occluding cerumen; occluding cerumen; and fully non-occluding cerumen and debris). Chi-square analysis was performed to study the association between hearing aid use and cerumen impaction. RESULTS: The current study results showed no association between hearing aid use and cerumen impaction. Also, there was no association between right/left ear and cerumen impaction. CONCLUSIONS: These results interesting and contrary to our assumption that hearing aid use increases the likelihood of cerumen impaction. More well-controlled studies with prospective designs are needed to confirm if these results are accurate.

A Case of Chronic Suppurative Otitis Media with Facial Nerve Palsy due to Aspergillus Infection / 대한이비인후과학회지

Chronic otitis media of fungal origin and its complications like facial palsy are highly unusual. Although human exposure to Aspergillus is common, infections are infrequent. Aspergillus infections of the ear are usually limited to superficial growth on cerumen or moist debris. The main risk factor for fungal infection of middle ear is being in an immunocompromised state, which may be caused by malignant neoplasms, immunosuppressive therapy, poorly controlled diabetes mellitus, blood dyscrasia, or protein-energy malnutrition. Aggressive surgical debridement is required in fungal infections with facial palsy, and the prognosis is better with early treatment. Facial palsy caused by fungal infection showed poor improvement in most of the reported cases. Early diagnosis, surgical resection and antifungal therapy with control of underlying immunologic conditions and maintenance of antifungal therapy are required for best results. Fungal otitis media with facial nerve palsy has not yet been reported in Korea. We report a case of fungal otitis media with facial palsy in an immune-compromised woman who improved with mastoid process resection and facial nerve decompression.

Ear candling: a dangerous pleasure?

Ear candling is an alternative medicine practice alleged to enhance general health by putting an end of a hollow candle in the ear canal and lighting up the other end of it. It also is advertised for cerumen and debris [bacteria and fungi] removal. Ear candling is claimed to create negative pressure for drawing cerumen from the ear and to benefit the ears in many ways. It is however not free of complications and is now banned. Here we would like to highlight potential complications to this

study of cerumen hepatitis B infection in chronic hepatitis B patients by real-time PCR

The hepatitis B is a viral infection that causes a big problem globally. About 2 billion people worldwide are infected and there are now about 400 million HBV-DNA carriers around the world. HBV infection is the ninth cause of death worldwide and infects about 350 million new cases each year in the world. HBV-DNA can be spotted in different body secretions and fluids, including serum, saliva, tears, urine, amniotic fluid index, and cerumen isolated. This is a case - control study on the population of 140 participants [70 patients with chronic hepatitis B as cases and 70 healthy volunteers community as a control]. The presence of HBV-DNA in their serum and ears cerumen using qualitative PCR and quantitative molecular detection Real-Time PCR [BioRad-CFX system] was determined. Copy of serum HBV were detected in 98.5% of case group and 7% of healthy population [control group]. In case group, 61 patients [87.2%] had HBV-DNA in their cerumens and 5control subjects [about 7%] were positive for HBV-DNA in their cerumens. All patients group and two subject [2.8%] of control group, were positive in HBsAg test. Average HB virus genome load in cerumen and serum of chronic HBV patients [group] were 8.98x10[6] and 3.60x10[8] copies per ml of the sample respectively. Like other body secretions, Ear cerumen is constantly produced and is subject to a pathogen such as HBV infection. The possiblity of disease transmission seems unlikely through Cerumen, however considering the average copy of HBV genome in the cerumen, no doubt, it can be claimed that there is a potential transmission risk of HBV infection

Comparison of three different ceruminolytic agents [soda-bicarbonate, almond oil and normal saline] with respect to their efficacy

To compare the efficacy of three ceruminolytic agents for cerumen impaction with respect to its ease of complete removal via suctioning or probe. A comparative prospective study. This study was conducted carried out at the outpatient department of ENT, Abbasi Shaheed hospital, Karachi from November 2010 to March 2011. A comparative prospective study of 75 adult patients with cerumen impaction in either or both of the ears carried out at the outpatient department of ENT, Abbasi Shaheed hospital, Karachi. The study was done after taking the consent of the patients. All the adult patients of age 18 years or greater, of either sex with the symptoms in the ear[s] because of cerumen which was hard/dry and difficult to remove were included in the study. Those of age less than 18 years and not having any symptomatology because of the cerumen or with soft wax which was easy to clear were not included in the study. The study was carried out from November 2010 till March 2011. the patients with problematic, difficult to remove cerumen or cerumen impaction with symptoms were divided in to three groups: Groups A, Group B and Group c; all having equal number of cases that is 25 each. In group A they were given soda-bicarbonate in glycerin based ear drops; in group B almond oil and group C the normal saline for instillation in ear. The doses and timings for drops were equal in all the group and it was 3 drops in the affected ear every 6-hourly for 1-week. They were councilled that the dose should not be missed and they have to lay down for 5 minutes so that drops are absorbed and does not come out of the ear. After one week they were called in the OPD, was compared with completeness of removal of impacted cerumen for the three groups. Ease and completeness of cerumen removal was 80% in group A, followed by 60% for group C and 20% for group B. We found soda-glycerin to be superior to almond oil and normal saline as ceruminolytic agent

Effect of Otitis Media and Cerumen Occlusion on Body Temperature Measured by Thermometers / 소아감염

PURPOSE: To examine the effect of unilateral otitis media and unilateral cerumen occlusion of the ear canal on thermometers. METHODS: One hundred eighty six children with unilateral otitis media, fifty children with unilateral cerumen occlusion, and fifty children with neither otitis media nor cerumen were enrolled. Temperature was measured in both ear canals using thermometers. After 15 minutes, second temperature was measured again in both ears. Unilateral otitis media was graded by video otoscope for 7 grades. Differences in temperatures between affected ears and unaffected ears were analyzed. RESULTS: No temperature difference between the normal and cerumen groups was observed. The mean temperature of the otitis media ear canal was 0.13+/-0.20degrees C higher than that of the intact ear canal (36.99+/-0.54degrees C vs 36.86+/-0.52degrees C; P<0.001). There was no statistically significant temperature difference between grades. CONCLUSION: Unilateral otits media can affect estimation of body temperature measured by thermometers.

Emissões otoacústicas evocadas transientes e por produto de distorção em escolares / Transient evoked otoacustic emissions and distortion product in school children

Após os cinco anos de idade, a principal queixa em crianças que não ouvem normalmente é a dificuldade de aprendizagem. OBJETIVOS: Comparar os resultados suspeitos de perda auditiva pela triagem com os exames de emissões otoacústicas evocadas (EOAE) transientes (EOAT) e por produto de distorção (EOAPD), com dados dos exames audiométricos; observar qual dos dois procedimentos de EOAE responde melhor para triagem em escolares. MATERIAL E MÉTODOS: Avaliar 451 escolares da 1ª série do ensino fundamental, em escolas públicas de São Luís. Foram feitos, na própria escola, os exames otoscópicos com remoção de cerume quando necessário e os exames de EOAT e EOAPD em todos os escolares. Nas crianças que apresentaram alteração em algum dos exames de EOAT e/ou EOAPD foram realizadas a audiometria e imitanciometria. FORMA DE ESTUDO: Prospectivo Transversal. RESULTADOS: Freqüência de 18,6 por cento de rolhas de cerume. Após triagem com EOAT e EOAPD não foi encontrada diferença estatisticamente significante quando comparamos os resultados dos exames que falharam somente nas EOAT e EOAPD com dados dos exames audiométricos, no entanto quando comparado esses dados com falha nos dois exames houve diferença significante (p<0,05). CONCLUSÃO: Os dois procedimentos de EOAE respondem bem á triagem auditiva em escolares.

Past five years of age, the main complaint of children who are hard of hearing is that they have difficulty in learning. AIM: Compare these results to suspected hearing loss, through triage with the exams of evoked otoacoustic emissions (EOAE) transients (TEOAE) and by distortion product (DPEOAE), using data from audiometric exams; observe which of the procedures of EOAE better respond to school children triage. MATERIALS AND METHODS: To evaluate 451 school children, grade one students, from the public schools in São Luís. At school, otoscopic exams with the removal of wax and the TEOAE and DPEOAE exams were also carried on all school children. Audiometry and acoustic impedance were performed on the children who presented alterations at any point during the TEOAE and/or DPEOAE exams. STUDY DESIGN: Transversal- Prospective. RESULTS: 18.6 percent had ear wax. As for the TEOAE and DPEOAE triage, no significant statistic difference was found when comparing the results of the exams which failed only in the TEOAE and DOEOAE with audiometric exam data, nonetheless, when comparing this failure data to both of these exams there was a significant difference (p<0.05). CONCLUSION: Both EOAE procedures responded well to the hearing triage in school children.

Magnitude of impacted earwax in Oman, its impact on hearing impairment and economic burden of earwax on health services.

BACKGROUND: Wax in ear canal causes a sizeable burden on resources of health services to a country. AIM: The magnitude of impacted wax, its effect in a survey and cost of managing this problem were reviewed in 2002. SETTINGS AND DESIGNS: A study was conducted during 1996 to estimate the magnitude and causes of hearing impairment and ear diseases in Oman. The authors further reviewed the data of community-based prevalence study to assess the role of impacted wax. MATERIALS AND METHODS: Trained physicians used portable audiometers to test the hearing status of each ear. They used otoscopes to examine the ear. Persons suspected to have hearing impairment or ear disease were reexamined by audiologists and otologists to determine the causes of hearing impairment. The resources for managing impacted wax were also calculated. RESULTS: In this survey, 11,402 subjects of all ages were examined. Prevalence of impacted wax was 11.7% (CI 95% 11.1-12.2). Impacted wax was significantly higher in females compared to males [RR = 1.22 (CI 95% 1.10-1.35)]. It was more common in residents of regions with humid environment than those of regions with less humidity [RR = 1.91 (CI 95% 1.67-2.18)]. Impacted wax in ear canal was associated with ear diseases. A total of 181,000 Omani people were estimated to have impacted wax in the ear canal. Managing impacted wax could cost 3.6 million US dollars to the ear care services. CONCLUSIONS: Impacted wax was a hindrance in the hearing survey and countries should plan to deal with earwax in such surveys. Its impact on hearing impairment and resource burden should be considered while formulating policies for ear care.

Adenoid cystic carcinoma of ceruminous gland: a case report.

Adenoid cystic carcinoma of the external auditory canal (EAC) is a very rare malignant tumor and its diagnosis is frequently missed because of the superficial nature of biopsies. A 30 year old male presented with 6 months history of recurrent painful right ear discharge. On examination there was a nodule of 2 cms in diameter. The microscopic examination of the punch biopsy specimen of tumor revealed typical features of an adenoid cystic carcinoma. While reporting the biopsies of external auditory canal one should keep the adenoid cystic carcinoma as one of the possible differentials, especially if the biopsy is superficial, problem is recurrent and histopathological features suggest the granulation tissue.

A Clinicomycologic Study of Dermatophytosis of the External Auditory Meatus / 대한피부과학회지

BACKGROUND: Otomycosis is a mycotic disease of the external auditory meatus. Aspergillus is the most common pathogen. Despite the fact that a great number of fungi are considered as the cause of otomycosis, otomycosis due to dermatophytes occurs with great rarity. OBJECTIVE: The purpose of this study was to investigate clinical and mycological features of dermatophytosis in the external auditory meatus. METHODS: We performed a clinical and mycologic analysis of 17 patients who had been clinically and mycologically diagnosed with dermatophytosis of the external auditory meatus. In addition, amplication of TRS-1 and TRS-2 of the ribosomal DNA nontranscribed spacer was performed on strains of Trichophyton (T.) rubrum and T. raubitshcekii which were isolated from skin lesions of the external ear and cerumen in 6 patients. RESULTS: The ratio of male to female patients was 1.4:1. The age of patients were 6 to 72 and mean age of onset is 36.4. Eleven patients had concomitant dermatophytosis of other sites. Tinea unguium was combined in 7 cases, tinea pedis in 4 cases, tinea corporis in 3 cases, tinea manus in 2 cases and tinea cruris in 1 case. The positive rate of KOH examination was 88.2% and the positive rate of fungal culture on PDAC media was 88.2%. The most common organism cultured was T. rubrum (80.0%), followed by T. raubitschekii (13.3%) and T. mentagrophytes (7.7%). Ten patients were treated with topical terbinafine and seven patients with oral itraconazole, so all patients were cleared of fungi from the external auditory meatus and inflammation was resolved. With TRS-1 and TRS-2 amplication, 4 of 5 pairs of T. rubrum and 3 strains of T. raubitshcekii showed the same types regardless of the site in each patient. CONCLUSION: Dermatophytosis occurs rarely in the external auditory meatus but we experienced 17 cases of dermatophytosis at this site. With suspected otomycosis, dermatophytosis of the external auditory meatus and concomitant dermatophytosis must be investigated and treated simultaneously to prevent any recurrence.

A comparative study of common ear morbidity pattern among the primary school children of an urban slum of Kolkata and rural area of Hooghly.

A cross-sectional, clinical and epidemiological study was undertaken among 627 primary school children (rural 145, urban 482) to compare the common ear morbidity pattern between an urban slum of kolkata and a rural area of Hooghly. Middle ear pathology was found to be present in 20% and 12.6% among rural and urban students respectively. Cerumen in the external auditory canal was the commonest clinical finding in both the areas and was found to be present in 35.86% of rural and 30.70% of urban population respectively. Smoke nuisance, bathing in open ponds and overcrowding were some of the predisposing factors causing ear diseases, like chronic suppurative otitis media and serous otitis media.

A Clinical Analysis of Surgical Treatment for Axillary Osmidrosis by the Bipedicle Flap Method and CO2 Laser / 대한피부과학회지

BACKGROUND: Axillary osmidrosis is caused by excessive secretion of apocrine sweat, which causes foul odor and extreme social embarrassment. Axillary osmidrosis can be treated by a number of methods, but surgery is the treatment of choice. OBJECTIVE: The purpose of this study was to evaluate clinical results of surgical treatment for axillary osmidrosis by the bipedicle flap method and CO2 laser. METHODS: December 1995 and December 2002, 53 patients with axillary osmidrosis were treated by the bipedicle flap method and with CO2 laser. Post-operative complications and convalescent time in the patients (106 axillae) were then of evaluated. Among them, 37 patients were followed up for a minimum 6 months, and the patients were asked to complete a questionnaire on their family history, aggravation factors, association with wet ear wax or palmoplantar hyperhidrosis, degree of satisfaction, decreased sweating, decreased axillary hair, tension on motion, and scarring. RESULTS: Follow-up ranged from 6 to 84 months (mean: 41months). Thirty one (83.8%) out of 37 patients were satisfied or partially satisfied with the results. Six (16.2%) out of 37 patients were dissatisfied. Post-operative complications were seen in 27 (25.5%) out of 106 axillae. The average convalescent time was 18 days. CONCLUSION: Based on the long-term evaluation, this bipedicle flap method and CO2 laser treatment were found to be effective for axillary osmidrosis.

Microbiologic Study of the Ear Canal in Koreans / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: This study was designed to isolate bacteria and fungi from healthy ear canal in Koreans and compare with known pathogens. SUBJECTS AND METHOD: Specimens were collected from the external ear swab and cerumen of 45 healthy volunteers from February 2003 to May 2003. RESULTS: Forty-five subjects were cultured. In 8 subjects, we failed to obtain enough cerumen. Three canal and 11 cerumen showed no growth. Forty-two canal specimens yielded 72 microorganisms, of which 84.7% were gram positive bacteria. Twenty-six cerumen specimens yielded 43 microorganisms and 76.7% of them were gram positive. Staphylococci was 76.4% of canal bacteria and 74.4% of cerumen bacteria. In both canal and cerumen, the most commonly isolated microorganism was Staphylococcus capitis. Coryneform bacteria were 6.9% of bacteria in canal and were not isolated from cerumen. Two Aspergillus species and one Penicillium species were isolated from canal and cerumen. CONCLUSION: Coagulase-negative staphylococcus (CNS) were found to be the predominant microorganism and, in particular, Staphylococcus capitis was the most commonly isolated microorganism from the normal external auditory canal in Koreans.

Predictors of hearing loss in school entrants in a developing country.

BACKGROUND: Hearing loss is a prevalent and significant disability that impairs functional development and educational attainment of school children in developing countries. Lack of a simple and practical screening protocol often deters routine and systematic hearing screening at school entry. AIM: To identify predictors of hearing loss for a practical screening model in school-aged children. SETTINGS AND DESIGN: Community-based, retrospective case-control study of school entrants in an inner city. METHODS: Results from the audiologic and non-audiologic examination of 50 hearing impaired children in randomly selected mainstream schools were compared with those of a control group of 150 normal hearing children, matched for age and sex from the same population. The non-audiologic evaluation consisted of medical history, general physical examination, anthropometry, motor skills, intelligence and visual acuity while the audiologic assessment consisted of otoscopy, audiometry and tympanometry. STATISTICAL ANALYSIS: Multiple logistic regression analysis of significant variables derived from univariate analysis incorporating student t-test and chi-square. RESULTS: Besides parental literacy (OR:0.3; 95% CI:0.16-0.68), non-audiologic variables showed no association with hearing loss. In contrast, most audiologic indicators, enlarged nasal turbinate (OR:3.3; 95% CI:0.98-11.31), debris or foreign bodies in the ear canal (OR:5.4; 95% CI:1.0-36.03), impacted cerumen (OR:6.2; 95% CI:2.12-14.33), dull tympanic membrane (OR:2.2; 95% CI:1.10-4.46), perforated ear drum (OR:24.3; 95% CI:2.93-1100.17) and otitis media with effusion OME (OR:14.2; 95% CI:6.22-33.09), were associated with hearing loss. However, only parental literacy (OR:0.3; 95% CI:0.16-0.69), impacted cerumen (OR:4.0; 95% CI:1.66-9.43) and OME (OR:11.0; 95% CI:4.74-25.62) emerged as predictors. CONCLUSION: Selective screening based on the identification of impacted cerumen and OME will facilitate the detection of a significant proportion of hearing impaired school entrants.

Cost-effectiveness of audiometric screening of first-year preparatory pupils in Dhofar region, Oman

Audiometric screening was conducted in Dhofar region to study the magnitude of ear problems and cost-effectiveness of screening first-year preparatory-school children in Oman. None of the 1894 pupils had otitis media with effusion or sensory neuronal hearing loss. Six children [0.32%] had impacted wax, 4 [0.21%] chronic suppurative otitis media and 2 [0.11%] dry perforation of eardrum. In all, 14 children [0.74%] with suspected hearing impairment were referred to a specialist but only 2 attended. Physicians and nurses spent 8-10 minutes for ear examination per child for a yield of less than 1%. The screening expenditure was US$ 5 per pupil. As the prevalence of serious ear conditions was low, we conclude that exp and ing the audiometric screening of schoolchildren to first-year preparatory pupils is not cost-effective
