Clinical Study The Role of H. pylori in the Development of Laryngeal Squamous Cell Carcinoma

Aim. This study aims to investigate the possible role of H. pylori as a cause of laryngeal squamous cell carcinoma. Method. This controlled study was performed with 31 consecutive laryngeal cancer and 28 cancer-free patients who underwent direct laryngoscopy and biopsy of laryngeal lesions. To document the previous H. pylori infection, serological analysis of the antibody titers was done. Immunohistochemical analyses were applied to the tissue samples. Results. Serology was found positive at the 90.3% of the laryngeal cancer patients and 96.4% of the benign group. There were no statistically significant differences between the two groups ( > 0.05). Immunohistochemical analysis results were determined as negative at all of the specimens of laryngeal cancer patients and patients with benign lesions. Conclusion. There were no signs of colonization of H. pylori in laryngeal tissues of both groups' patients. It is thought that no relationship exists between the H. pylori infection and laryngeal squamous cell carcinoma

BACTERIOLOGY OF CHRONIC SUPPURATIVE OTITIS-MEDIA

Aspiration of exudate through an open perforation was performed in 183 patients with chronic otitis media. The pus was cultured aerobically and anaerobically. Aerobes only were isolated from 71 patients (39%); 20 patients (11%) had only anaerobes; and 91 patients (50%) had both aerobes and anaerobes. Only 1 specimen had no growth. There were 259 aerobic isolates. Pseudomonas aeruginosa was recovered from 68 patients. Other aerobes commonly recovered included Staphylococcus aureus and Klebsiella pneumoniae. There were 178 anaerobic isolates. Only anaerobic gram-positive cocci were isolated in 20 instances. Sixty-three Bacteroides isolates were recovered, including 12 Bacteroides fragilis group and 21 Bacteroides melaninogenicus
