11/16. clozapine and the development of salivary gland swelling: a case study.BACKGROUND: clozapine is a novel antipsychotic that is effective in 30% to 50% of treatment-resistant schizophrenia. It is known to cause sialorrhea in 23% of patients. This phenomenon is paradoxical and poorly understood since clozapine is known to have potent anticholinergic effects. We have observed the development of transient salivary gland swelling in four patients on clozapine therapy. Although not clearly related to sialorrhea, this phenomenon may share a similar pathophysiology. METHOD: A retrospective chart review was performed on the 4 of 27 patients started on clozapine treatment during a 6-month period who developed salivary gland swelling. RESULTS: Four patients, none of whom had previously complained of sialorrhea, developed salivary gland swelling after starting clozapine treatment. In all cases, the swelling resolved within days. A possible etiology may be the formation of a calculus that blocks the duct and causes swelling, which resolves when the stone passes. CONCLUSION: Clinicians should be aware that salivary gland swelling may be a possible side effect of clozapine use.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |

14/16. Removal of a submandibular duct calculus with a vascular snare.Conventional management of calculi in the distal portion of the submandibular duct involves surgery under general anaesthesia. We report here a patient whose calculus was successfully removed non-surgically as an outpatient with a vascular snare.- - - - - - - - - - ranking = 5keywords = calculus (Clic here for more details about this article) |
15/16. Submandibular sialolithiasis with concurrent sialoadenitis in a child.Sialolithiasis is a relatively common condition in adults, but it is rarely observed in children. We report a case in a 7-year-old child with a sialolith in the anterior right Wharton's duct resulting in a submandibular sialoadenitis. Under local anesthesia the calculus was removed by means of a sialodochotomy. Post-operative recovery was uneventful and follow-up examinations showed recovery of the function of the affected gland.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
16/16. Intra-oral ultrasound imaging of a submandibular duct calculus.A case is presented showing the first reported use of a small, digitally-guided, intra-oral ultrasound probe to image a calculus in a submandibular salivary duct. This use of intra-oral ultrasound is discussed in the context of the overall current status of intra-oral and extra-oral ultrasound imaging. It is proposed that using a combination of intra-oral and extra-oral probes, the whole of the salivary apparatus may now be examined sonographically for the presence of calculi.- - - - - - - - - - ranking = 5keywords = calculus (Clic here for more details about this article) |
