HDR syndrome, detected in the neonatal period by newborn hearing screening.

Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome is an autosomal dominant disorder. Because HDR syndrome is caused by haploinsufficiency in GATA3, it exhibits variation in the onset and progression of hearing loss. In previous reports, the automated auditory brainstem response (AABR) was considered insufficient to detect sensorineural hearing loss caused by HDR syndrome.

The Transition of Pediatric Tracheobronchial Foreign Body Cases in the Past 36 Years: A Retrospective Single-Center Study in Japan.

Tracheobronchial foreign bodies (TFBs) are pediatric airway emergencies frequently seen. We aimed to examine the changes in the clinical characteristics of pediatric TFB patients in a single institution within the past 36 years. We retrospectively reviewed the data of 85 patients aged 0-10 years with TFBs lodged in the trachea or bronchus admitted at the Department of Otolaryngology-Head and Neck Surgery at Tohoku University Hospital between 1986 and 2021.

Effects of Unilateral Vagotomy on LPS-Induced Aspiration Pneumonia in Mice.

Respiratory-related dysphagia and aspiration pneumonia can be attributed to multiple causes. However, reproduction of multiple factor-related respiratory distress and aspiration pneumonia in a single animal model is challenging. To validate animals with vagal nerve palsy as novel models for severe aspiration pneumonia associated with respiratory distress, we investigated the effects of unilateral vagotomy on the swallowing function and severity of pneumonia after forced aspiration in mice.

Interferon therapy for hepatocellular carcinoma patients with low HCV-RNA levels.

Background/aims: Interferon-alfa is widely used for the treatment of chronic hepatitis C, and has been thought to have a preventive effect on the development of hepatocellular carcinoma. Hepatocellular carcinoma develops from chronic liver diseases such as chronic hepatitis C or liver cirrhosis. We studied the effect of interferon for liver cirrhosis with hepatocellular carcinoma after treating hepatocellular carcinoma itself.
