The induction of Fos immunoreactivity in the pyriform cortex and the hippocampal formation after closed head injury was determined and compared to that seen following cortical needle injury in pentobarbital anaesthetized male rats. Robust Fos expression was observed in the ipsilateral pyriform cortex following both types of injury but was observed in the ipsilateral dentate gyrus only following...

BACKGROUND Congenital nasal pyriform aperture stenosis is a rare and potentially lethal form of airway obstruction in newborns. Immediate recognition and appropriate therapy are mandatory for this potentially life-threating condition. This anomaly may present as an isolated malformation or may be associated with other cranial-facial anomalies. Clinically, CNPS shows unspecific symptoms of nasal...

Acute suppurative thyroiditis is a rare disease because the thyroid gland is remarkably resistant to infection. We present a 2-year-old girl with refractory acute suppurative thyroiditis due to a pyriform sinus fistula (PSF). She complained of fever and painful anterior neck swelling. Her condition did not completely improved by multiple parenteral antibiotics along with incision and drainage. ...

since then on account of inability to standand walk freely. She gave a history of complete amenorrhcea. On admission she was put to bed and examined. She was lean, weak and anaemic. Her breasts were fairly developed. There was a soft fluctuating pyriform swelling about the size of a coconut in the middle of the lower part of the abdomen, extending up to the umbilicus. On auscultation no foetal

We describe a case of prenatal diagnosis of a pharyngeal cyst as a pyriform sinus fistula on the findings of ultrasonography and magnetic resonance imaging.
