This is a review of the geographic distribution of oropharyngeal cancers and of chewing habits which involve various plant materials and additives including lime. Cancers in the oropharynx and esophagus may be induced by the same carcino gens. Suspected plant carcinogens in the environments of patients with high frequencies of cancers of the oropharynx or esophagus are being tested in hamster c...

BACKGROUND Transoral robotic-assisted oncologic surgery of the head and neck offers promising functional results. Nonetheless, the efficacy of oncologic surgery remains critically dependent on obtaining negative margins. We aimed to integrate a miniaturized high-resolution fiber-optic microendoscope (HRME), which provides real-time histological assessment, with the da Vinci robotic system (Intu...

INTRODUCTION Abscesses after open cholecystectomies have been reported to occur in less than 1% of patients. The majority of these abscesses are colonized by gastrointestinal tract flora. It is clearly known that Haemophilus parainfluenza is a normal inhabitant of the human respiratory tract. However, its origin and route of transmission into the gastrointestinal tract is unknown. CASE PRESEN...

We have assessed the efficacy of tracheal tube cuff inflation in the oropharynx as an aid to blind nasotracheal intubation in 20 ASA I and II patients undergoing elective oral surgery. The trachea was intubated once using the technique of tracheal tube cuff inflation in the oropharynx and once keeping the tracheal tube cuff deflated throughout the manoeuvre. With the cuff deflated, intubation w...

BACKGROUND The newly developed narrowband imaging (NBI) gastrointestinal endoscope makes possible the detection of superficial carcinoma in the oropharynx and hypopharynx, which is difficult with the conventional laryngoscope. Here, we investigated whether the combined use of laryngoscope with NBI allows the detection of superficial carcinoma in this region. METHODS A total of 51 superficial,...

Background. Although alcohol and tobacco use are known risk factors for development of squamous cell carcinoma in the head and neck, human papillomavirus (HPV) has been increasingly associated with this group of cancers. We describe the case of a married couple who presented with HPV-positive oropharynx squamous cell carcinoma within two months of each other. Methods. Tumor biopsies were positi...

Rapid antigen and antibody, serological tests, and RT ‑ PCR-based molecular methods are widely used for the detection of microorganisms worldwide. Objectives: This study aimed by Isothermal nucleic acid amplification techniques to detect the covid-19. Methods: In this study, 200 samples of nasopharynx and oropharynx were collected from Jamaran Heart Hospital in Tehran. Covid -19 was exami...

Recent findings indicate that the microbiota is involved in development of lung cancer by inducing inflammatory responses and generating genome damage. This study aimed to compare sputum microbiomes from mouth oropharynx non-small cell carcinoma (NSCLC) patients. A second goal was search for bacterial taxonomic units behave differently microbiome NSCLC patients healthy subjects. In study, compo...

BACKGROUND Schwannomas are benign, encapsulated, peripheral nerve tumours that arise from the Schwann cell. Approximately 25%-45% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck. However, schwannoma of the supraglottic oropharynx is rare. CASE PRESENTATION We report on a 35-year-old female who complained of progressive dysphagia, from wh...
