Toothbrushes are the most common cause of foreign body injury to the oral cavity in children, but complete impalement by a toothbrush is an extremely rare occurrence and has not been reported previously. This report describes a 28-month-old girl who fell from a 1m ledge while brushing her teeth. Her toothbrush penetrated the oral cavity and could not be removed, and so she was rushed to the hospital with the toothbrush in place. Contrast-enhanced computed tomography showed penetration of the toothbrush from the oral cavity into and through the right posterior neck at the level of the bifurcation of the common carotid artery. Angiography was performed under general anesthesia, and the toothbrush was removed. In consultation with pediatricians, antibiotic infusion therapy was started, and the patient was extubated on the 5th post-operative day. There were no complications even after eating was resumed, and the patient was discharged on the 13th post-operative day. A toothbrush is an essential item in daily life, but it can cause serious injuries in children in some circumstances.

The clinical data of 115 patients with peritonsillar abscess (98 men and 17 women) treated between May 2011 and March 2014 were analyzed. We examined 9 items; the age, sex, affected side, duration of hospitalization, method of drainage, smoking history, history of diabetes, antibacterial drugs used, and the isolated bacteria. The disease predominantly affected males in their 30s (27.8% of all the patients). The median duration of hospitalization was 7 days. In regard to the affected side, the right side was affected in 52%, the left side in 44%, and both sides in 4%. The method of drainage used was incision in 63%, and puncture in 37%. In regard to the personal and past medical history, 51% of patients had a history of smoking and 3.5% had a history of diabetes. ABPC/SBT was used as the single-agent antibacterial drug in 75% of cases. The most commonly isolated aerobic bacteria were α-hemolytic streptococci, and the most commonly isolated anaerobic bacteria were Prevotella. The duration of hospitalization showed no significant correlation with the smoking history, drainage method or the antibiotic treatment used (ABPC/SBT single-agent or multiple drug use). On the other hand, the duration of hospitalization was significantly longer in the more than ≥65 years' age group than in the <65 years' age group. Therefore, especially careful interventions for prevention and treatment of peritonsillar abscess are required in the elderly. In relation to antibiotic selection, it may be reasonable to expect sufficient effect with the use of ABPC/SBT as a single agent, as this antibiotic has a broad antibacterial spectrum covering aerobic, anaerobic and drug-resistant bacteria.

Background The postoperative reconstruction of ear canal cancer with a local flap such as the snail flap technique has been reported for cases with few tissue defects. The snail flap technique requires a large skin incision and is at risk of facial neuropathy. We have devised a new flap that addresses these problems. Methods An 80‐year‐old woman underwent total right ear canal resection for cancer of the right ear canal, and the defect of the ear canal was reconstructed using a local flap. The local flap was used by making a rectangular incision in front of the auricle and rolling it into a cylindrical shape. We named this flap a square screw flap. Results The patient was discharged 1 week after surgery without complications. Conclusions This method is considered to be useful for reconstruction of the ear canal with a small defect.
