A case of peripheral odontogenic fibroma arising in the mandibular premolar region of a teenager.

Peripheral odontogenic fibroma (POdF) is a rare, benign ectomesenchymal tumor. Herein, we report a case of a 15-year-old female patient who developed POdF in the mandible. The lesion was resected along with the periosteum. Histopathological findings revealed a small mass and cord-like epithelium. There was no recurrence 16 months postoperatively.

Elongated styloid process syndrome with prolongation of the superior cornu of the thyroid cartilage: A case report.

INTRODUCTION: Elongated styloid process syndrome represents a group of symptoms, such as recurrent throat pain and neck pain, caused by elongation of the styloid process. We report a case of elongated styloid process syndrome with prolongation of the superior cornu of the thyroid cartilage. CASE PRESENTATION: A 50-year-old man was referred to our clinic with the chief complaint of discomfort on the right side of his neck. He had no history of any disease. Extraoral findings indicated pain during neck rotation. Computed tomography showed prolongation of the styloid process beyond the mandibular plane and close to the hyoid. Moreover, prolongation of the superior cornu of the thyroid cartilage was detected. The discomfort during rotation of the neck was due to the stimulation by the styloid process. Styloid resection was performed using the extraoral approach under general anesthesia. CONCLUSION: Discomfort in the neck was resolved after operation.

Accelerated decline in pregnancy rate after in vitro fertilization and embryo transfer in 35-41-year-old women: 15 years' experience in the Okinawa Islands, Japan.

Aim: To describe 15 years of in vitro fertilization and embryo transfer (IVF-ET) treatment at University Hospital, with special reference to a potential association between pregnancy rate and patient age. Methods: A retrospective analysis of 2355 IVF-ET cycles carried out in 789 patients was undertaken. The main outcome measures were ovarian response, fertilization rate and pregnancy rate. Results: Pregnancy rates in ET cycles carried out in women aged between 23 and 46 years fell significantly with patient age, with a more rapid decline after 35 years and particularly between 35 and 41 years. Almost all laboratory findings were significantly worse with increased patient age, although fertilization rate did not drop with age. The spontaneous abortion rate increased drastically with age and the vast majority of abortions resulted from chromosomal abnormality. Conclusion: It is essential to provide infertile women with practical and reliable information on the age-associated pregnancy rate for appropriate counseling and to encourage them to seek IVF-ET treatment at an earlier age.
