Rapidly maturing juvenile ossifying fibroma: a case report.

This report describes an unusual case of juvenile ossifying fibroma (JOF) in a 16-year-old female patient with a clinical presentation of a single large, well-circumscribed swelling on left side of the palate. Ossifying fibromas are normally slow growing benign lesions. Radiographically they can present as radiolucent, mixed or radiopaque lesions depending on the degree of maturity. A period of at least 6 years is required for the lesion to pass from the radiolucent to radiopaque stage. All previously reported cases of JOF have been either radiolucent or mixed density lesions, but our case is unusual because the lesion had shown apparently rapid transformation into an almost complete radiopaque stage at a very early age.

Comparative evaluation of gustatory function between postmenopausal women and age-matched men.

OBJECTIVE: The aim of the study was to compare the gustatory function between postmenopausal women and age-matched men. SUBJECTS AND METHODS: During a period of 4 months, 30 postmenopausal women and 30 age-matched men were prospectively evaluated for gustatory function. Each subject was given a symptoms questionnaire for self-assessment of taste function. Then, whole mouth taste test was performed in which the quality identification and intensity ratings of taste solutions were measured. RESULTS: Regarding correct quality identification, the results were statistically non-significant (P > 0.05). As far as the intensity judgments are concerned, significant difference exists between postmenopausal women and age-matched men. Intensity of taste perception for sucrose was significantly lower in postmenopausal women than intensity of taste perception for other tastes (P < 0.05). One of the noticeable findings is that 15 (50%) postmenopausal women reported a change in dietary habits; all expressed liking for sweeter food. CONCLUSION: Postmenopausal women appeared to have a reduced perception of sucrose, which can alter eating habits, such as intake of more sweet foods, whereas no significant difference is observed in taste perception of NaCl, citric acid and quinine hydrochloride between postmenopausal women and age-matched men. Fifteen (50%) postmenopausal women stated fondness for sweet taste.

Evaluation of the efficacy of colour Doppler ultrasound in diagnosis of cervical lymphadenopathy.

OBJECTIVES: The purpose of the study was to evaluate the efficacy of colour Doppler ultrasound (CDUS) to differentiate between benign and malignant cervical lymph nodes. METHODS: During a period of 12 months, 100 untreated patients with clinical evidence of cervical lymphadenopathy (50 patients with clinically suspected malignant/metastatic cervical lymphadenopathy and 50 patients with clinically suspected reactive/benign cervical lymphadenopathy) were prospectively evaluated with CDUS. CDUS was performed for 168 cervical lymph nodes in these 100 patients. Histopathological confirmations were obtained by fine needle aspiration biopsy and/or excisional biopsy. To evaluate the efficacy of CDUS, comparison between clinical features, CDUS features and cytological/histological features of enlarged cervical lymph nodes was then done. RESULTS: Initially, clinical examination evaluated 143 cervical lymph nodes. CDUS evaluation discovered additional 25 lymph nodes (143+25 = 168). Correlation of patterns of colour Doppler flow signals with pathological diagnosis showed that central flow for benign nodes and peripheral flow for malignant nodes were highly significant parameters (P < 0.01). CDUS has a higher specificity than clinical evaluation, being 94.28% and 58.76%, respectively. Accuracy of the CDUS examination was also definitely higher than clinical evaluation at 92.85% and 63.67%, respectively. CONCLUSIONS: Nodal vascularity can be used to differentiate benign from malignant lymphadenopathy. Proper judicious CDUS examination provides an opportunity to eliminate the need for biopsy/FNAC in reactive nodes.
