Cancer is one of the social health problems in Turkey. Oral and pharyngeal cancer, grouped together, is the sixth most common cancer in the world. Most of the oral cancers occur in men aged 50 years and older; however, during last 3 decades, the number of patients worldwide is being diagnosed with head and neck squamous cell carcinoma at a younger age (<45 years old) to be encountered more frequently. Main treatment options for oral and oropharyngeal cancers are surgery, radiotherapy and chemotherapy. Head and neck radiation, chemotherapy, and blood and marrow transplantation can cause oral complications ranging from dry mouth to life-threatening infections. The aim of this review is to update our knowledge on oropharyngeal cancer, to evaluate the effects of cancer therapies on oral region and to emphasize the important role of dentists in diagnosis and treatment planning of cancer.

Papillomavirus infection is a very common and mainly sexually transmitted disease in humans. The development of HPV infection may start from uterine cervix, other lower genital area mucosa and oral mucosa. HPV can cause subclinical or clinical infections. Clinical infections associated with HPV are genital papillomas, skin papillomas, recurrent respiratorial papilomatosis, intraepithelial squamous lesions, cervix, oral cavity and oropharyngeal cancer. Approximately 20% of oral cancers and 60-80% of oropharyngeal cancers are thought to be due to HPV infection. Since the introduction of HPV vaccine in many European countries in 2007, more than 40 countries have launched HPV vaccination in national immunization programs. Physicians responsible for the treatment of oropharyngeal and oral cavity cancer should be knowledgeable about HPV vaccination and should follow developments in technology to reduce HPV-associated infections and cancers.

Tularemia is zoonotic disease caused by Francisella tularensis. Most of the cases in Turkey are the oropharyngeal form but a few cases of glandular tularemia have been reported. We present a 4-year-old patient with intestinal invagination caused by mesenteric adenitis due to glandular tularemia. There are a few reports on mesenteric adenitis due to tularemia but none had invagination. We felt our case deserved to be presented as it is the first such case. [ABSTRACT FROM AUTHOR]
