Parotid gland keratocystoma: a rare diagnosis of a neck lump.

Keratocystoma of the parotid gland is a rare benign tumour, with only a handful of case reports in literature. We report a case of a man in his 70s who presented to the head and neck clinic with a 2-month history of a gradually increasing left neck swelling. Fine-needle aspiration showed contents of an epidermal cyst; however, an MRI showed a solid/cystic mass with a low T2 signal, suggesting increased risk of malignancy.

Mumps presenting with unilateral, synchronous parotid and submandibular gland swelling.

A previously healthy 22-year-old woman presented with acute, unilateral facial and neck swelling, associated with fever and malaise. She was initially treated with intravenous antibiotics; however, CT imaging showed unilateral, synchronous swelling and inflammation of the parotid and submandibular glands, and a PCR swab from the parotid duct was positive for mumps. She was fully immunised and had no contact in the preceding period with anyone diagnosed with mumps.

Ultrasonographic assessment of tonsillar volume in children.

Objectives: Adenotonsillar hypertrophy in children is the most common anatomical abnormality associated with obstructive sleep apnoea. Perioperative complications associated with adenotonsillectomy are more common in children with severe obstructive sleep apnoea. An objective preoperative method to determine the size of tonsils is missing.

Sinonasal glomangiopericytoma: Is anything new?

More than 100 cases of sinonasal hemangiopericytoma have been reported in the literature, but only a handful of cases of nasal glomangiopericytoma. In this article, we report a case of a nasal glomangiopericytoma that was treated with endonasal surgical excision. We also attempt to clarify the confusion that attends to the nomenclature surrounding the terms glomangiopericytoma and hemangiopericytoma, which are often used interchangeably.

Idiopathic pseudoaneurysm: a rare cause of parotid mass.

A 77-year-old woman presented with a pulsatile blue-tinged mass over the left parotid, present for 5 years, and slowly enlarging. The size of the mass fluctuated during this period and there was no associated pain. The patient reported no history of surgery or trauma.

Periorbital emphysema after dive barotrauma without radiological evidence of paranasal sinus injury.

Background: Scuba diving has increased in popularity since its invention in 1943, with over 21 million PADI registered members worldwide. Injuries to the paranasal sinuses caused by barotrauma are the second most common after injury to the middle ear.

Case Report: In this paper we present a case of unilateral periorbital surgical emphysema in a 23-yr-old male commercial scuba diver with minimal symptoms following an uneventful 13-ft (4-m) dive.

Validity and reliability of the Greek version of the Quebec Back Pain Disability Scale.

Objectives: Low back pain is related to functional status and possible resulting disability. The Quebec Back Pain Disability Scale (QBPDS) has been used widely to evaluate functional disability in patients with low back pain. The purpose of this study was to assess: (a) the face and content validity, (b) the factor structure, (c) the concurrent validity, (d) the discriminant validity, (e) the internal consistency and the test-retest reliability (ICC) of the Greek version of the QBPDS.
