Suppurative inflammation of vas deferens: an unusual groin mass.
We report a case of suppurative vasitis that presented as an inguinal mass in a young man. Inflammation of the vas deferens may occur as a manifestation of genital tuberculosis or other genitourinary tract infection. A granulomatous vasitis, vasitis nodosa, is usually associated with previous trauma or surgery. Suppuration is rare. We report a case that represents a rare cause of an inguinal mass.

Location of the vibratory segment in tracheoesophageal speakers.
The Singer-Blom tracheoesophageal puncture procedure for surgical-prosthetic voice restoration has proved to be a viable option for alaryngeal speech rehabilitation. Following tracheoesophageal puncture, occlusion of the tracheostoma shunts pulmonary air through the Blom-Singer prosthesis into the cervical esophagus. The pulmonary air passing through the cervical esophagus and into the hypopharynx causes a portion of the upper alimentary tract to vibrate in a manner similar to that of the pharyngoesophageal segment during the production of esophageal speech. To study the location and shape of the vibratory segment in tracheoesophageal speakers, videofluoroscopy and simultaneous voice recording were performed with 16 patients. To analyze the vibratory segment(s), photographs were made of the videotaped image while it was stopped during the patients' production of the /a/ sound. The most frequent location of the vibratory segment was in the lower third of the neck, which corresponds to cervical vertebrae C5 through C7. Five of the subjects had two separate vibratory segments and two other subjects had long vibratory segments. The vibratory segment(s) in tracheoesophageal speakers was found to be similar to the vibratory segment(s) in esophageal speakers.
