    Background Hepatitis B is a disease that is prevalent worldwide and is responsible for 10% of the deaths that occur every year. The virus persists in 5% of infected adults and 90% of infected children and can cause chronic hepatitis. In addition to blood, the virus may also be present in other secretions. Transmission through saliva, sexual fluids, and urine has also been confirmed. Objectives The main aim of this study was to compare viral DNA copies in the serum, cerumen, and saliva of patients with HBeAg levels in their sera. Patients and Methods This was a cross-sectional study and subjects were selected by non-randomized methods. Serum, cerumen, and saliva samples were collected from 50 patients who were diagnosed with chronic hepatitis B about a year prior to the study. Enzyme-linked immunosorbent assay (ELISA) was performed to determine the presence of HBsAg and HBeAg in the gathered specimens. Viral DNA was extracted from specimens by using a Qiagen kit. The number of viral DNA copies was determined using a real-time polymerase chain reaction (PCR) assay. The study was performed in Ilam province in western Iran. Results Twenty-eight percent of the patients were HBeAg positive. The average number of viral copies in serum, cerumen, and saliva was higher in women than in men, and a significant correlation was observed between the gender and average viral copies. However, no significant correlation was observed between viral copies present in the serum and cerumen with the age and gender of patients. In addition, no correlation was observed between serum HBeAg and viral copies present in serum, cerumen, and saliva. The correlation analysis confirmed a direct and definite correlation between viral DNA loads in the patients’ serum and cerumen. Conclusions A significant direct correlation was observed between the viral DNA copies present in patients’ cerumen and serum. However, the correlation between saliva viral load with serum and cerumen viral load was

    Full Text Available Introduction: The purpose of this study was to evaluate anthropometric parameters of lip - nose complex in 11-17 years old males in Mashhad using photographic analysis.   Materials and Methods: Number of 357 Fars boys (11-17 years old, residence in Mashhad were included in this study. They were all class.I. Some frontal and lateral photographs of natural head position were taken by a digital camera. After landmark determination, anthropometric parameters including alar width, mouth width, nose height, cupid arch width, vertical height of lips, columellar width, nasolabial angle and nasal root slope angle were determined by Smile Analyzer software while Kruskal – Wallis test was used for data analyses. Results: This study revealed that alar width, nasal height and mouth width were increasing gradually within 11 to 16 years of age. But nose height to nose width proportion did not show any significant differences in different age groups (P=0.097. Nasolabial angle in different age groups had no significant statistical differences and it was between 95.83 and 100.05 (P=0.315. However for Cph-Cph, the distance was decreasing first and then increasing with no significant differences among age groups. Conclusion: Except significant differences observed in different age groups about nasolabial angle and nasal index, there were not any other significant differences for other anthropometric parameters. It could be helpful in orthodontic and surgical treatment planning.

    Full Text Available Introduction: In spite of the fact that acute otitis media is a systemic and symptomatic disease with sever otalgia, otitis media with effusion (OME is an asymptomatic and silent disease. OME is the most common cause of conductive hearing loss in children and has adverse effects on speech development and cognitive skills. Results: Among 1001 children under study, 57 subjects (5.7% were diagnosed with OME, more than 50% of which were asymptomatic. Periodic otalgia and turning up television volume were the most common symptoms. Conclusion: Regarding the improved knowledge on diagnosis and treatment of OME especially in younger children, hearing problems or cognitive and linguistic skills retardation may be avoided by promoting general information.

    Full Text Available 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.

    The first recorded electroantennographic preliminary studies on stingless bees have been performed using two species of Frieseomelitta from Brazil. Experiments with F. silvestrii and F. varia showed that antennae respond to hexane extracts of heads and abdomens of both species and posterior tibia of F. silvestrii (which carry plant resin), as well as to the pure compounds 2-heptanol and 2-nonanol, which occur in the mandibular glands of both species, and to the terpenes alpha-cubebene, humulene, and beta-caryophyllene found on their tibia and in the cerumen of their nests.

    Stingless bees collect plant resins and make it into propolis, although they have a wider range of use for this material than do honey bees (Apis spp.). Plebeia spp. workers employ propolis mixed with wax (cerumen) for constructing and sealing nest structures, while they use viscous (sticky) propolis for defense by applying it onto their enemies. Isolated viscous propolis deposits are permanently maintained at the interior of their colonies, as also seen in other Meliponini species. Newly-emerged Plebeia emerina (Friese) workers were observed stuck to and unable to escape these viscous propolis stores. We examined the division of labor involved in propolis manipulation, by observing marked bees of known age in four colonies of P. emerina from southern Brazil. Activities on brood combs, the nest involucrum and food pots were observed from the first day of life of the marked bees. However, work on viscous propolis deposits did not begin until the 13th day of age and continued until the 56th day (maximum lifespan in our sample). Although worker bees begin to manipulate cerumen early, they seem to be unable to handle viscous propolis till they become older. PMID:21120374

    Full Text Available With the aim to study the histologic lesions caused by Psoroptes cuniculi, the ears of 15 adult goats were collected in a slaughter house in the city of Patos, state of Paraíba, in the Brazilian semiarid region. Five goats had crusts and exudates in the external ears and were infested by 21 to 189 mites in each ear. Another 10 goats were asymptomatic, five of which had 14 to 39 mites and five of which were non-infested. From the five goats with clinical signs, three presented moderate macroscopic lesions with cerumen and dry crusts in both ears, affecting the pinna and ear canal. Two other goats presented mild lesions, characterized by exudates in the pinna without crust formation. The histologic lesions included varying degrees of parakeratotic hyperkeratosis, orthokeratotic hyperkeratosis, acanthosis, hypergranulosis, spongiosis, and dermatitis, with rare eosinophils. P. cuniculi were observed in the ear canal, occasionally in contact with the stratum corneum, but without causing traumatic lesions in the epithelium, which suggests that the lesions occur through a mechanical effect due to the presence of the mites together with the exudates, cerumen, and keratin residues.

    Full Text Available 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

    Although cerumen management (CM) is routinely performed by audiologists in some countries, this is currently not the case in the Republic of Ireland. This study involved surveying the opinions of Audiologists and Ear Nose and Throat specialists (ENTs) in relation to audiologists conducting CM. In total, 20 ENT Consultants (29%) and 51 audiologists (64%) in the public services responded to an online survey. There was agreement that CM should be within audiologists\\' remit. However, with regard to risk, opinions were significantly different, with 15 ENTs (75%), compared to 14 audiologists (27%), in agreement that CM management by audiologists was more risky to patients. Nevertheless, 62 respondents (87%) supported future CM training for audiologists. The. overall similarities of opinion between the two groups contrasted to previous studies that reported strong opposition from ENTs with regard to audiologists managing earwax.

The DPOAE is an objective exam, fast, non painful, non invasive and easy to prescribe for screening in patients with hearing loss, and allow diagnoses and early rehabilitation. STUDY DESIGN: Transversal cohort. MATERIAL AND METHOD: All children of Lar da Criança in Marília, SP, after previous authorization of the responsible, were submitted to on otorhinolaryngology exam and DPOAE. RESULTS: The results presented that one hundred and five children participated in the study and 44,76% presented cerumen. Twelve children even after use of ceruminolytic and ear clearing persist with cerumen, or don't have parents or responsible permission. These children were exclude in the study. and 93 children were submitted to DPOAE After doing DPOAE in 93 patients, 5,37% were changed; 60% were male and 60% had bilateral changed. DISCUSSION: The results were lower than the results find in literature, even the male predominance. Besides, we observe high prevalence of cerumen in our patients. CONCLUSION: Its essential an otorhinolaryngology evaluation before doing the DPOAE. It could be done in newborn, children and adults for early detection and prevention of failure in the cognitive and psycho-emotional development.

    Lipid-rich matrices are often sinks for lipophilic contaminants, such as pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Typically methods for contaminant extraction and cleanup for lipid-rich matrices require multiple cleanup steps; however, a selective pressurized liquid extraction (SPLE) technique requiring no additional cleanup has been developed for the simultaneous extraction and cleanup of whale earwax (cerumen; a lipid-rich matrix). Whale earwax accumulates in select whale species over their lifetime to form wax earplugs. Typically used as an aging technique in cetaceans, layers or laminae that comprise the earplug are thought to be associated with annual or semiannual migration and feeding patterns. Whale earplugs (earwax) represent a unique matrix capable of recording and archiving whales' lifetime contaminant profiles. This study reports the first analytical method developed for identifying and quantifying lipophilic persistent organic pollutants (POPs) in a whale earplug including organochlorine pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). The analytical method was developed using SPLE to extract contaminants from ∼0.25 to 0.5g aliquots of each lamina of sectioned earplug. The SPLE was optimized for cleanup adsorbents (basic alumina, silica gel, and Florisil(®)), adsorbent to sample ratio, and adsorbent order. In the optimized SPLE method, the earwax homogenate was placed within the extraction cell on top of basic alumina (5g), silica gel (15g), and Florisil(®) (10g) and the target analytes were extracted from the homogenate using 1:1 (v/v) dichloromethane:hexane. POPs were analyzed using gas chromatography-mass spectrometry with electron capture negative ionization and electron impact ionization. The average percent recoveries for the POPs were 91% (±6% relative standard deviation), while limits of detection and quantification ranged from 0.00057 to 0.96ngg(-1

    Full Text Available Objective: To measure external ear resonant amplitude and frequency in children (3-7 years old and to compare with adult measures. Method and materials: The external ear resonance peak amplitude and frequency of 63 children 3-7 years old were recorded. All of the children had normal tympanogram and there was no cerumen in external auditory canal. 20 adult of 21-24 years old (10 male , 10 female were selected in order to compare with children that had normal tympanogram. The tests included : 1-otoscopy 2- tympanometry 3-microphone probe tube test. Results: The average of resonance peak frequency for children and adult is 4200 Hz and 3200 Hz , respectively. The resonance frequency of children had significantly diffrence with average of resonance frequency in adults. The average of resonance peak amplitude for children and adult is 17.70 dB and 17.17 dB , respectively. Conclusion: Resonant frequency and amplitude affect the hearing aid prescription and fitting process and calculating insertion gain; so, this measures seem should be considered in children hearing aid fitting.

    Ear cleaning helps maintain the normal otic environment and is important in the treatment of otitis. Over cleaning, however, may trigger otitis through maceration of the epidermal lining. Simple manual cleaning is useful for routine cleansing but doesn't remove tightly adherent debris. Bulb syringes are more vigorous but may damage the ear in inexperienced hands. Devices using mains water pressure or dental machines are also available. Thorough cleaning of the ear canals and middle ear cavity can only be achieved by retrograde flushing using specially adapted catheters, feeding tubes or video otoscopes under anaesthesia. Myringotomy, inspection and cleaning of the middle should be performed if the tympanic membrane appears abnormal. There are a wide variety of cleaning fluids available. Ceruminolytics soften and dissolve cerumen to facilitate cleaning. Surfactants emulsify debris, breaking it up and keeping it in solution. Astringents dry the ear canal surface, preventing maceration. Maintaining a low pH and incorporating antimicrobial agents can inhibit microbial proliferation and glucocorticoids can be used to reduce inflammation. Adverse effects and contraindications following ear cleaning can include maceration, contact reactions, otitis media, ear canal avulsion, vestibular syndrome, Horner's syndrome, facial nerve paralysis and deafness. Care should be exercised in selecting cleaning fluids if the tympanic membranes are ruptured. PMID:15030561

    Full Text Available At the beginning of 2005, an outbreak of ceruminous otitis has been observed in a breeders flock belonging to the Robusta Lionata breed, a native chicken breed reared in a Centre for the valorisation and conservation of native poultry breeds. The disease caused a high morbidity rate (90% of birds, whereas the mortality affected only 10% of the birds. The death of the birds was preceded by clinical signs, such as worsening of the ceruminous otitis with abundant secretion of bad-smelling cerumen, lack of appetite and depression. The otitis externa, mainly bilateral, was the only evident finding at necropsy. Laboratory examinations showed only the presence of Mycoplasma synoviae, either by isolation on culture media or by PCR, on ear and choana samples. Aspergillus fumigatus was detected only in one bird. In this paper, the Authors report for the first time on an outbreak of ceruminous otitis in native chicken breeds and point out that the only pathogenic agent isolated from the birds has been Mycoplasma synoviae.

    Residues of antineoplastic drugs in canine excretion products may represent exposure risks to veterinary personnel, owners of pet dogs and other animal care-takers. The aim of this study was to measure the extent and duration of platinum (Pt) excretion in pet dogs treated with carboplatin. Samples were collected before and up to 21 days after administration of carboplatin. We used validated, ultra-sensitive, inductively coupled plasma-mass spectrometry assays to measure Pt in canine urine, faeces, saliva, sebum and cerumen. Results showed that urine is the major route of elimination of Pt in dogs. In addition, excretion occurs via faeces and saliva, with the highest amounts eliminated during the first 5 days. The amount of excreted Pt decreased over time but was still quantifiable at 21 days after administration of carboplatin. In conclusion, increased Pt levels were found in all measured excretion products up to 21 days after administration of carboplatin to pet dogs, with urine as the main route of excretion. These findings may be used to further adapt current veterinary guidelines on safe handling of antineoplastic drugs and treated animals. PMID:23714139

    AIM: To review published methods for detection of hepatitis B virus(HBV) infection.METHODS: A thorough search on Medline database was conducted to find original articles describing different methods or techniques of detection of HBV, which are published in English in last 10 years. Articles outlining methods of detection of mutants or drug resistance were excluded. Full texts and abstracts(if full text not available) were reviewed thoroughly. Manual search of references of retrieved articles were also done. We extracted data on different samples and techniques of detection of HBV, their sensitivity(Sn), specificity(Sp) and applicability.RESULTS: A total of 72 studies were reviewed. HBV was detected from dried blood/plasma spots, hepatocytes, ovarian tissue, cerumen, saliva, parotid tissue, renal tissue, oocytes and embryos, cholangiocarcinoma tissue, etc. Sensitivity of dried blood spot for detecting HBV was > 90% in all the studies. In case of seronegative patients, HBV DNA or serological markers have been detected from hepatocytes or renal tissue in many instances. Enzyme linked immunosorbent assay and Chemiluminescent immunoassay(CLIA) are most commonly used serological tests for detection. CLIA systems are also used for quantitation. Molecular techniques are used qualitatively as well as for quantitative detection. Among the molecular techniques version 2.0 of the Cobas Ampliprep/Cobas Taq Man assay and Abbott’s real time polymerase chain reaction kit were found to be most sensitive with a lower detection limit of only 6.25 IU/m L and 1.48 IU/m L respectively. CONCLUSION: Serological and molecular assays are predominant and reliable methods for HBV detection. Automated systems are highly sensitive and quantify HBV DNA and serological markers for monitoring.

    The objectives of this study were to evaluate noise levels generated during micro-suction aural toilet using an anatomic silicon ear model. It is an experimental study. In an anatomic ear model made of silicone, the eardrum was replaced by a 1-cm diameter microphone of a calibrated sound-level measuring device. Ear wax was removed using the sucker of a standard ENT treatment unit (Atmos Servant 5(®)). Mean and peak sound levels during the suction procedure were recorded with suckers of various diameters (Fergusson-Frazier 2.7-4 mm as well as Rosen 1.4-2.5 mm). Average noise levels during normal suction in a distance of 1 cm in front of the eardrum ranged between 97 and 103.5 dB(A) (broadband noise). Peak noise levels reached 118 dB(A). During partial obstruction of the sucker by cerumen or dermal flakes, peak noise levels reached 146 dB(A). Peak noise levels observed during the so-called clarinet phenomena were independent of the diameter or type of suckers used. Although micro-suction aural toilet is regarded as an established, widespread and usually safe method to clean the external auditory canal, some caution seems advisable. The performance of long-lasting suction periods straight in front of the eardrum without sound-protecting earwax between sucker and eardrum should be avoided. In particular, when clarinet phenomena are occurring (as described above), the suction procedure should be aborted immediately. In the presence of dermal flakes blocking the auditory canal, cleaning with micro-forceps or other non-suctioning instruments might represent a reasonable alternative. PMID:22740154

    Full Text Available Otomycosis is a fungal infection of the external ear canal with only a few studies about its real frequence in Brazil. AIM: to evaluate otomycosis frequence and characteristics in patients with clinical suspicion of external otitis. STUDY DESIGN: Retrospective study with transversal cohort (2000-2006. MATERIALS AND METHODS:103 patients were assigned to mycological diagnosis (direct microscopic examination and culture. RESULTS: Otomycosis was diagnosed in 19.4% of the patients. Patient age varied from 2 to 66 years (an average of 23.5 years of age, and 60% of otomycosis cases were seen in women between 2 to 20 years of age. Chronic otitis, previous antibiotic therapy and the lack of cerumen were predisposing factors; itching, otalgia, otorrhea and hypoacusis were the symptoms reported by the patients. The most frequently isolated species were C. albicans (30%, C. parapsilosis (20%, A. niger (20%, A. flavus (10%, A. fumigatus (5%, C. tropicalis (5%, Trichosporon asahii (5% and Scedosporium apiospermum (5%. CONCLUSIONS: Otomycosis is endemic in João Pessoa-PB. Clinical exam and mycological studies are important for diagnostic purposes because otomycosis symptoms are not specific.Otomicose é uma infecção fúngica do conduto auditivo externo com poucos estudos sobre sua real frequência no Brasil.
