Expression of neutrophil gelatinase-associated lipocalin in human salivary glands.

Objectives: We performed an observational study of RNA and protein expression in human tissue to examine the distribution of neutrophil gelatinase-associated lipocalin (NGAL) in normal and chronic inflammatory salivary tissues, and to investigate the expression level of NGAL in inflammatory conditions of salivary glands.

Methods: Normal salivary gland tissues and tissue samples of salivary glands with chronic sialadenitis were obtained. Expression of NGAL was investigated by reverse transcriptase-polymerase chain reaction, and semiquantitative analysis of these results was also performed.

Endoscopic treatment of nasolacrimal sac obstruction secondary to fibrous dysplasia of paranasal sinuses.

Fibrous dysplasia involving paranasal sinuses mostly has asymptomatic features, but sometimes may cause signs and symptoms which relate to the location and extent of bony abnormalities. The use of endoscopic nasal surgery for debulking ethmoidal fibrous dysplasia, blocking the left nasolacrimal sac and simultaneous intranasal endoscopic dacryocystorhinostomy with silicone intubation is presented. The procedure and advantages of endoscopic approach over the external approach are outlined in this paper.

Efficacy of sucralfate in the postoperative management of uvulopalatopharyngoplasty: a double-blind, randomized, controlled study.

Objective: To evaluate the effectiveness of sucralfate in influencing throat pain, otalgia, analgesic requirement, bleeding, mucosal recovery, and incidence of postoperative bleeding in patients undergoing uvulopalatopharyngoplasty.

Design: A prospective double-blind randomized study.

Setting: University-affiliated tertiary referral hospital.

Nasal septal abscess: An unusual presentation of dentigerous cyst.

Dentigerous cyst is one of the most prevalent types of odontogenic cysts and is associated with crown of an unerupted or developing tooth. Dentigerous cysts are usually asymptomatic, so facial swelling may be the first clinical sign of a dentigerous cyst. A dentigerous cyst forming a septal abscess is uncommon.
