The epidemiology of Epstein-Barr virus (EBV) infection in populations at different risk for EBV-associated diseases indicates significant differences between the populations. EBV infection takes place much earlier in Uganda, where all children are infected before the age of 2 to 3 years, than in Southeast Asia, where nasopharyngeal carcinoma is prevalent. It is proposed that such early infectio...

During a 9-month period, we evaluated the relative sensitivity of throat and nasopharyngeal swab cultures for isolation of Bordetella pertussis. Of 38 pertussis cases, 36 (95%) had positive nasopharyngeal cultures, while only 16 of 36 (44%) had positive throat cultures. There were no cases of nasopharyngeal-negative, throat-positive cultures. The sensitivity of the direct fluorescent-antibody t...

a three-member family from tehran referred with variety of nasopharyngeal symptoms including sneezing, coughing and nasal discharge following consumption of barbecued liver (kabab).  thirteen worm-like nymphs of linguatula serrata were separated from larynx, nose and gum of these patients. the adult parasites live in the nose and paranasal sinuses of dogs and other carnivores.  although this in...

INTRODUCTION Nasopharyngeal carcinoma among the children has been rare accounting for only 1% of all pediatric malignancies. Both genetic and environmental factors have contributed to the development of nasopharyngeal carcinoma. Among the children there was a higher rate of undifferentiated histology. The mean age of nasopharyngeal carcinoma diagnosis has been 11 years old age; and the most com...

Anesthesiology, V 125 • No 3 596 September 2016 A double modified nasopharyngeal airway connected to a breathing circuit to assist ventilation could be a great rescue airway technique. This setup provides unobstructed spontaneous ventilation, end-tidal carbon dioxide monitoring, continuous positive airway pressure, and assisted ventilation as needed.1 A modif...

Primary nasopharyneal tuberculosis is a rare disease which is commonly present with cervical lymphadenopathy. It is hard to differenciate the diagnosis of tuberculosis from nasopharyngeal carcinoma. Histologic and bacteriologic evaluation is required for diagnosis. A male patient at the age of nineteen applied to our clinic with the complaints of a mass in the neck, congestion in the nose, nigh...

BACKGROUND Nasopharyngeal carcinoma with leptomeningeal involvement is rare and typically has poor prognosis. METHODS AND RESULTS We present a case report of a patient with nasopharyngeal carcinoma who was treated with high-dose intravenous methotrexate and remains asymptomatic and without clinical evidence of disease 6 years later. CONCLUSIONS Systemic high-dose methotrexate should be eval...

Epstein-Barr virus (EBV) belongs to the herpesvirus group and is associated with a wide spectrum of clinical diseases. Primary EBVinfection usually occurs within the first 3 years of life and is almost always asymptomatic (1). By contrast, primary infection in Western countries is often delayed until the second decade or later, and induces infectious mononucleosis, which may rarely be complicat...

Cancer is a complex group of diseases with multiple eventual causes. The underlying causes are not fully known. Thus, learning more about the known causes of cancer is an important issue. Moreover, among these factors, infection and its association to cancers is controversial. Although, it seems that the genome instability of the cells can initiate cancer development. The purpose of this review...
