Ear, nose and throat foreign bodies in children: A search for socio-demographic correlates

OBJECTIVE Ear nose and throat foreign bodies in children are one of the most common emergencies faced by otorhinolaryngologists. Our objective in the study conducted in the otolaryngology department of R.G. Kar Medical College & Hospital was to find out the socio-demographic correlates of self inflicted foreign body insertion in ear-nose-throat in children presenting in out patient department and emergency. METHODS A cross sectional descriptive study was conducted from October 2009 to March 2010 in the out patient department and emergency of otolaryngology. Using a predesigned and pretested questionnaire, socio-demographic data was collected prospectively on every alternate day by examining clinically all new pediatric patients attending with self-inflicted foreign body and interviewing their caregivers after removal of foreign body. The data collected from 288 children was analyzed by using simple proportion, odds ratio with 95% confidence interval, χ(2), t-test and analysis of one way variance (ANOVA) test. Epi info 3.4.3 version (CDC, Atlanta, retrieved from WHO website, on 01.11.09) and SPSS 17.0 were used for statistical calculations. RESULTS Analysis showed male preponderance (59.72%) of cases from urban area (63.9%), predominance of 0-5 years age group with 5.19 ± 3.02 (mean ± standard deviation) years average age, nasal foreign body was on the top (44.4%), majority from low income (58.33%) joint family (65.3%) with housewives (75.0%) as primary care giver, majority of whom reported to have nil or low literacy (61.1%). 19.4% subjects having local pathology showed significant association with urban residence, joint family, low socio-economic status and two or less than two children of the mother of the participant children. Past history of similar incidence was found in 22.2% of study subjects and significantly associated with nasal foreign body insertion and higher among the children of housewives. CONCLUSIONS Increasing awareness of the prime caregivers by the routine grass root level health workers may be tried to reduce incidence of this risky health event and capacity building of the Primary level physicians to handle foreign body insertion cases can lessen the stress of the victim children and their parents.

Unusual Presentations of Adenoid Cystic Carcinoma in Extra-Salivary Gland Subsites in Head and Neck Region: A Case Series

Adenoid cystic carcinoma (ACC) is an uncommon malignant epithelial tumor occurring in head neck region, accounting for approximately 10% of all salivary gland neoplasms. Extra-salivary gland involvement of other head neck subsites by ACC may present in unusual modes creating clinical dilemma. Here we present some cases with extra-salivary gland ACC. In this series six cases with extra-salivary gland ACC were included. Three patients presented with external auditory canal and temporo-mastoid region involvement of whom two cases also had intracranial extension. In one case tongue was the site of involvement where it was confused with benign neurogenic tumour. Palatal erosion with formation of oro-nasal fistula was the the manifestation of ACC involving palate. On the other hand sinonasal bleeding mass which came out as ACC on histopathological examination did not cause any palatal erosion and was removed successfully via lateral rhiniotomy. In all these cases patients were treated with post-operative radiotherapy and were closely followed up for early detection of any distant metastasis. The experience about the various unusual manifestations of ACC and the therapeutic challenge poised by the cases is discussed here.

Precise energy eigenvalues of hydrogen-like ion moving in quantum plasmas

The analytic form of the electrostatic potential felt by a slowly moving test charge in quantum plasma is developed. It has been shown that the electrostatic potential is composed of two parts: the Debye-Huckel screening term and the near-field wake potential. The latter depends on the velocity of the test charge as well as on the number density of the plasma electrons. Rayleigh-Ritz variational calculation has been done to estimate precise energy eigenvalues of hydrogen-like carbon ion under such plasma environment. A detailed analysis shows that the energy levels gradually move to the continuum with increasing plasma electron density while the level crossing phenomenon has been observed with the variation of ion velocity.

Pediatric Otolaryngological Emergency: An Experience from a Tertiary Care Teaching Institution at Kolkata, India

AbstractOtolaryngological conditions constitute a major share of emergency medical problem among children. The present study was conducted to assess the patient profiles, incidences morbidities, mode of presentation and managements of different otolaryngological emergencies among pediatric patients presented in a tertiary care hospital. Descriptive cross-sectional study by analysing retrospectively collected information pertaining to the patients attended ENT emergency service department of a tertiary care hospital, Kolkata. Data were collected using predesigned proforma and were analysed with the help of SPSS version 20. About 39.0% of total ENT emergency attendance was contributed by pediatric age group. The male female ratio was 1:1.33 with average age of 58.95 ± 34.42 (mean ± SD) months. Half of the attendees had ear problem and almost one-third reported complaints related to nose. The major complaints at the time of presentation were earache (32.3%), nasal foreign body (24.0%) and aural foreign body (13.3%) closely followed by aero-digestive tract foreign body (12.0%). Inflammatory conditions affected the ears more, foreign bodies found most commonly in nose and miscellaneous condition such as impacted wax was found to be related to ear in significantly higher proportion. Conservative management was provided to 96.25% of patients. Foreign body insertion was found to be associated with lower age group. Most of the emergencies were managed conservatively which might be done at subdivision or district level to reduce the undesirable burden on the tertiary care medical colleges.
