BackgroundThe benign tumors of nasopharynx are least encountered tumors in otolaryngology, as nasopharynx is considered one of notorious anatomical site for the malignant tumors. Pleomorphic adenoma of the minor salivary gland of nasopharynx and parapharyngeal space is rare. We present a pleomorphic adenoma of minor salivary gland which was mismanaged.Case presentationAn adult male presented with left nostril obstruction for five months. The examination found big mass extending from nasopharynx to oropharynx. On CT scan, this tumor was quite big and extending to the parapharyngeal space. The FNAB found it a carcinoma but it did not respond to radiotherapy. The excision biopsy of tumor revealed it as pleomorphic adenoma. We found only five published reports on this tumor arising from nasopharynx.Discussion and conclusionAlthough, in this case report exact origin of the tumor could not be ascertained as it also appeared to be a parapharyngeal tumor but we kept the possibility of a nasopharyngeal tumor on the basis of clinical features. The pleomorphic adenoma of nasopharynx is rare. It can be misdiagnosed as malignant epithelial tumor on histopathology. The differentiation from its malignant variant is also difficult. A possibility of benign tumor should always be kept in nasopharyngeal growth with no evidence of metastasis, and histopathological diagnosis of growth should be available before any definitive treatment.

Tuberculosis of parotid is a rare clinical entity, and cases of bilateral tubercular parotitis are even rarer. We present a case of bilateral primary parotid tuberculosis in a 49-year-old female. The patient received anti-tuberculosis treatment for six months, resulting in complete resolution of the disease. We also review the theories related to the pathogenesis of tubercular parotitis, and propose a novel hypothesis about greater involvement of parotid gland as compared to other salivary glands in primary tuberculosis.

<p class="abstract"><strong>Background:</strong> Organophosphate (OP) poisoning is a common cause of significant mortality and morbidity all over the world. In Asia, OP poisoning is the most common form of fatal self harm. Previous studies have suggested hearing loss due to OP poisoning. The aim of the study was to study audiological assessment in the patients with OP poisoning.</p><p class="abstract"><strong>Methods:</strong> 26 patients (age &lt;50 years) of OP poisoning over a period of one year were included in the study following ethical approval from Institute Ethics Committee. 25 healthy subjects served as control. Each subject was subjected to brainstem evoked response audiometry (BERA) examination.  </p><p class="abstract"><strong>Results:</strong> 50% patients with OP poisoning were aged between 20-29 years. Male outnumbered females in the patients (M:F- 17:9) as well as controls (M:F- 17:8). Only absolute wave-v latency (ms) was statistically significantly prolonged in cases when compared with controls in both right (0.035) as well as left ears (0.048). We found no statistical significant difference in interpeak wave I-III, III-V, I-V latency of both ears in cases when compared with controls. On second assessment in the patients, we observed a statistical significant decrease in absolute wave III and V latency, and interpeak I-III interval in right ear when compared with wave latency at first assessment. In left ear on second assessment, a significant decrease in absolute wave I, III, and V latency was observed in the patients.</p><p class="abstract"><strong>Conclusions:</strong> OP compounds may affect entire neural auditory pathway. Further studies with a large sample size are required for the assessment.</p>

Background: The head and neck are two of the most common sites of extranodal non-Hodgkin's lymphoma (NHL). However, primary tumors of the infratemporal fossa are infrequent, and NHL in this region is extremely rare.

<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">Hearing impairment is most frequent sensory deficit in human population. The disease burden estimations based on sound epidemiological research provide the foundation for appropriate public policy focus and measures for effective management of disease conditions. Data regarding the magnitude of hearing impairment in our country is limited and the literature search revealed that no such studies have been conducted in this region. </span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">A community based cross sectional observational study was carried out among the 306 individuals in rural area of Shimla district, Himachal Pradesh. Information was obtained by a structured questionnaire, clinical ENT examination and audiological tests after obtaining informed consent.  </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">The study group had 52.6% males and 47.4% females. Maximum 26.5% of individuals were in the age group of 31-45 years. Mean age was 36.56±18.83. The prevalence of hearing impairment was 16.7%. Among individuals with hearing loss, maximum 52.9% were in the age group of ≥60 years. Sensorineural hearing loss was found in 68.6%, maximum 56.9% had mild hearing loss. Among majority of individuals with hearing loss cause was presbyacusis 52.9% followed by infectious ear disease 33.3%.</span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">In the present study, prevalence of hearing loss was found to be 16.7% and predominantly mild sensorineural or conductive type of hearing loss. An early intervention and quality patient education is necessary for prevention of hearing impairment in majority of cases.</span></p>
