Fish Tank Granuloma Presenting as a Nasal Cavity Mass.

is a free-living nontuberculous mycobacterium that is widely distributed in freshwater and seawater around the world. Granulomatous skin infection from in people who are exposed to fish or aquatic environments is a rare condition known as fish tank granuloma. The granuloma mainly occurs on the skin of the upper limb, in a few cases on the face, and rarely in the nasal cavity.

Proposal for a Modified Jaw Opening Exercise for Dysphagia: A Randomized, Controlled Trial.

Objective: To verify the feasibility and effectiveness of a newly developed modified jaw opening exercise (MJOE) in post-stroke patients with pharyngeal residue who completed a sixweek exercise regimen.

Design: Double-blind, randomized, controlled trial.

Participants: 16 patients with stroke-related dysphagia.

Concurrent chemoradiotherapy with docetaxel for T2 laryngeal carcinoma.

Objective: To evaluate the efficacy and safety of concurrent chemoradiotherapy with docetaxel (DOC) for T2 laryngeal carcinoma.

Method: Twelve patients with T2 laryngeal cancer received concurrent chemoradiotherapy (60-70Gy) with weekly DOC (10 mg/m2) (CCRT group). The clinical files of the patients were retrospectively reviewed and survival rates and laryngeal preservation rates were analyzed compared with the group treated with conventional radiation therapy alone (RT group).

A survey of head and neck malignancy at Tokai University Hospital.

Patients with head and neck malignancy who visited Tokai University Hospital over seven years were statistically surveyed. Six hundred and eighty-three patients were newly registered in this period. The most frequent primary lesion was the larynx (29.

[Promoter hypermethylation of tumor-associated genes in head and neck cancer].

An important pathway of gene transcriptional inactivation is hypermethylation at the CpG islands of promoter regions. Some tumor suppressor genes have been reported to harbor promoter hypermethylation in head and neck cancer. We studied DNA hypermethylation of 4 genes in 42 cases of primary head and neck cancer.

A case of accessory parotid gland tumor.

We herein describe a case of accessory parotid gland tumor, including diagnosis and surgical approach. The accessory parotid gland is salivary tissue separated from the main parotid gland and lying on masseter muscle. It has secondary duct empting into the Stensen's duct.

Airway management during the laryngoscopic surgery for the benign laryngeal obstructive disease.

The airway management and anesthesia maintenance during the laryngoscopic surgery is essential for a safe operation. For the benign laryngeal obstructive disease such as a large mass or a foreign body of the upper airway, it is difficult to secure the airway. Sometimes they might be hazardous and potentially lethal.

[Prophylactic neck dissection for submandibular gland cancer].

The indication and preferred dissection field for prophylactic neck dissection for submandibular gland cancer are controversial and have not been standardized. We reviewed 27 patients who underwent a definitive operation for previously untreated submandibular gland cancer. The 27 patients consisted of 13 patients with adenoid cystic carcinoma, 6 patients with mucoepidermoid carcinoma, 6 patients with adenocarcinoma, and 2 patients with squamous cell carcinoma.
