Pyoderma gangrenosum is a rare ulcerative condition associated with various systemic diseases. Lesions on the lower extremities and the trunk are common, but lesions on the nose are rare. Here we report a case of pyoderma gangrenosum on the nose.

Pretreatment monocyte counts and neutrophil counts predict the risk for febrile neutropenia in patients undergoing TPF chemotherapy for head and neck squamous cell carcinoma.

Background: Febrile neutropenia (FN) is the most serious hematologic toxicity of systemic chemotherapy. However, accurate prediction of FN development has been difficult because the risk varies largely depending on the chemotherapy regimen and various individual factors.

Methods: We retrospectively analyzed diverse clinical factors including pretreatment hematological parameters to clarify the reliable predictors of FN development during chemotherapy with a docetaxel, cisplatin, and fluorouracil (TPF) regimen in patients with head and neck squamous cell carcinoma.

Association between tinnitus retraining therapy and a tinnitus control instrument.

Objective: Tinnitus retraining therapy (TRT), which is an adaptation therapy for tinnitus based on the neurophysiological model proposed by Jastreboff in 1990,consists of directive counseling and acoustic therapy with a tinnitus control instrument (TCI) or other devices. For the past 5 years, our hospital has administered TRT characterized by the use of a TCI.

Method: In this study, we reviewed the clinical course of patients with tinnitus who presented to our outpatient clinic for tinnitus and hearing loss during the 3-year period from April 2004 to March 2007 and underwent TRT with a TCI.

Liposarcoma of the retropharyngeal space: report of a case and review of literature.

Liposarcoma is a soft tissue malignant tumor that is common in adults, though the incidence of this type of tumor in the head and neck region is extremely low. Herein, we report a case of myxoid liposarcoma occurring in the retropharyngeal space. We were unable to make a proper diagnosis of this tumor prior to surgery because of the radiographic findings and the anatomical location resembled those of neurogenic tumor.
