1/9. parotitis due to organophosphate intoxication.Acute pancreatitis due to pancreatic exocrine over-secretion induced by organophosphate poisoning has been previously reported but parotid gland involvement has not. This paper describes a case of acute organophosphate-induced parotitis in a patient with pre-existing sialolithiasis. The patient developed bilateral facial swelling in the pre-auricular area extending to the angle of the jaw and also developed elevated serum amylase on the second day of the poisoning. serum lipase remained normal. autopsy confirmed parotid gland inflammation and pre-existing ductal lithiasis. This case illustrates that organophosphate-induced parotitis can occur and should be considered in patients with organophosphate poisoning who have hyperamylasemia without elevation in serum lipase.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
2/9. Stensen's duct obstruction by foreign body and subsequent candidal infection of the parotid gland.A case of chronic inflammation complicated by Candida infection of the parotid gland in a 50-year-old woman is presented. This eventually proved to be caused by Stensen's duct obstruction due to an unusual radiolucent foreign body. The process that led to the proper diagnosis is presented and the importance of surgical exploration of the main duct in cases suggesting distal duct obstruction is stressed.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
3/9. The application of magnetic resonance imaging-guided fine-needle aspiration cytology in the diagnosis of deep lesions in the head and neck.PURPOSE: Image-guided fine-needle aspiration cytology (FNAC) may be useful as an alternative diagnostic approach to lesions in the head and neck. This study reports on the use of magnetic resonance imaging (MRI)-guided FNAC for diagnostic evaluation of deep lesions in this region. MATERIALS AND methods: This was a prospective study of 12 patients with deep lesions in the head and neck who underwent MRI-guided FNAC at the Shanghai 9th People's Hospital. A 0.2-T open magnet was used for MRI and localization of the 20-gauge MRI-compatible needle. All of the aspirated samples were stained with hematoxylin and eosin and examined by a cytopathologist. RESULTS: The needle in all 12 cases was displayed on MRI in the central portion of the lesion under the guidance of MRI; 12 of 12 patients (100%) had diagnostic aspirations and none needed open biopsy for more specific histologic interpretation. Six of these 12 patients with tumors (4 malignant, 2 benign) underwent operative treatment with positive postoperative pathologic results. One patient had a diagnosis of inflammation. The diagnostic accuracy was 91.67% (11 of 12), the sensitivity was 85.71% (6 of 7), and the specificity was 100% (5 of 5). There were no false-positive results and 1 false-negative result, for a false-negative rate of 14.29% (1 of 7). All aspiration procedures were well tolerated and without complications. CONCLUSIONS: MRI-guided FNAC is a cost-effective tool for establishing tissue diagnosis as a primary investigative modality. It is helpful and accurate in the diagnosis of deep lesions in the head and neck and in follow-up of patients, thereby avoiding further surgical intervention.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
4/9. Recurrent pneumoparotid: cause and treatment.OBJECTIVE: To document the etiology and successful treatment of severe recurrent pneumoparotid. STUDY DESIGN: Computed tomography, ductal measurement by probe size, surgical treatment. RESULTS: We performed a superficial parotidectomy for a 13-year-old with a history of recurrent parotitis. He subsequently developed recurrent pneumoparotid in the contralateral gland with subcutaneous dissection of air into the face, neck, and mediastinum. At surgery, Stensen's ducts were measured and found to be abnormally patent bilaterally compared to standardized norms. Parotid duct ligation, commonly used for sialorrhea, was employed as a novel treatment and was curative. CONCLUSION: insufflation of air into the parotid duct system can trouble woodwind instrument players, can complicate dental procedures, or can be self-induced. It is generally a benign condition requiring no therapy. Occasionally, pneumoparotid can be recurrent and lead to inflammation and infection of the parotid or subcutaneous emphysema. SIGNIFICANCE: In selected cases of recurrent pneumoparotid, ductal ligation may be curative.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
5/9. Infantile recurrent parotitis: follow up study of five cases and literature review.Recurrent parotitis (RP) is defined as recurrent parotid inflammation, generally associated with non-obstructive sialectasis of the parotid gland. It is a rare condition, and its etiology remains an enigma. AIM: The purposes of the present study were (1) to relate the follow up of five RP cases; (2) to examine the role of sialography and ultrasound in diagnosis and follow up; and (3) to make a literature review. STUDY DESIGN: Series review. MATERIAL AND METHOD: We reviewed all recurrent parotitis cases from the files of the otolaryngology Division at University of Sao Paulo, brazil. The criteria for inclusion were at least two years of evolution and more than one year and a half follow-up in our service. We included five children in the study. sialography was performed in the first evaluation and sonography was executed annually. Recurrent parotitis showed male predominance, and affected mainly children between the ages of 3 and 6. Frequency of crisis improved with time in all cases. sialography showed sialectasis aspect in the affected glands and sonographic exams demonstrated hypoechoic and heterogeneous internal echoes. One case showed regression of ultrasound changes after clinical improvement.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
6/9. Candida parotitis with abscess formation.This report describes the case of an elderly, diabetic man who developed acute suppurative parotitis with abscess formation. The causative agent of parotid abscess was candida albicans, which is an unusual cause of salivary gland pathology. The parotid gland is the salivary gland most commonly affected by inflammation. Acute parotitis occurs most often in elderly patients who are debilitated by systemic disease or are in a state of dehydration following major surgical procedures. Despite the high prevalence of oral candida carriage, there have been few previous reports of candida sialoadenitis in the literature. This is due to the toxicity of saliva to fungi under normal conditions. The diagnosis of candidiasis in our patient was made by culturing the purulent discharge from Stensen's duct and by culture of the pus obtained at surgical drainage of the abscess. After incision and drainage, the patient was treated with intravenous and then oral fluconazole for a total of 4 weeks with complete resolution of his condition. This case is interesting in light of recent and ongoing investigations of salivary proteins as potential new antifungal agents.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
7/9. parotitis and facial nerve dysfunction.Paralysis of the facial nerve in association with suppurative parotitis is rare, with only ten previously reported cases. In some situations, inflammation surrounding a benign neoplasm accounted for the observed paralysis. In this article, three new cases of parotitis with associated facial nerve dysfunction are described, none of which was associated with a neoplasm. In one, an occult abscess was present and in another an aggressive necrotizing process was seen. The treatment of this disease should initially be conservative management with high doses of wide-spectrum antibiotics. In the majority of cases, resolution of the facial paralysis should follow. However, persistence of a parotid mass with continued facial palsy mandates surgical exploration to exclude the presence of an underlying neoplasm.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
8/9. Intraductal tetracycline therapy for the treatment of chronic recurrent parotitis.Chronic recurrent parotitis (CRP) is recurrent parotid inflammation with non-obstructive sialectasis. Therapies which produce acinar atrophy or remove the acini are effective in treating CRP. Parotidectomy, tympanic neurectomy, duct ligation, and radiation therapy have either a low success rate or a high risk of morbidity. Intraductal antibiotic instillation has been proposed as a possible method of treatment. We hypothesized that the cytotoxic effects of tetracycline could produce acinar atrophy. A double-blind experiment of intraductal tetracycline instillation was performed in ten rabbits. Acinar atrophy and acute inflammation were found in 40% of the tetracycline treated glands; controls had a complete absence of these histologic changes. These results support the use of tetracycline instillation to produce acinar atrophy and therefore, intraductal tetracycline may be an effective, low-risk therapy for CRP. The clinical features of CRP will be reviewed and therapeutic implications discussed.- - - - - - - - - - ranking = 2keywords = inflammation (Clic here for more details about this article) |
9/9. Acute suppurative parotitis with spread to the deep neck spaces.This report describes the case of an elderly, diabetic woman who became dehydrated and developed acute suppurative parotitis, which caused marked swelling of her left face and neck. The parotid infection also extended by continuity into the lateral pharyngeal space and contiguous deep neck spaces, causing airway-threatening, extensive inflammation and swelling of the epiglottis and parapharyngeal soft tissues. The differential diagnosis and diagnostic rationale is discussed. The anatomy of the stylomandibular area is reviewed to explain how infection of the parotid can spread to the pharynx.- - - - - - - - - - ranking = 1keywords = inflammation (Clic here for more details about this article) |
