This is the first description of solitary phaeohyphomycosis affecting the mucosal surface. The lesion developed in the inferior lip of a 57-year-old woman. After surgical resection, histopathological examination evidenced characteristic brownish fungal structures within granulomatous-purulent inflammation. Amplification and sequencing of rDNA obtained from paraffin-embedded tissue identified Alternaria species, as the causative agent. (+info)
Sensory retraining after orthognathic surgery: effect on patients' perception of altered sensation.
(18/78)
PURPOSE: The primary research hypothesis was that the magnitude and duration of the perceived burden from altered sensation reported by patients after bilateral sagittal split osteotomy and trauma to the third division of the trigeminal nerve are decreased when facial sensory retraining exercises are performed in conjunction with standard opening exercises as compared with standard opening exercises alone. SUBJECTS AND METHODS: A total of 186 subjects were enrolled in a multicenter, double-blind, 2 parallel group-stratified block randomized clinical trial. Oral and facial pain, unusual sensations, numbness, and loss of sensitivity were scored from "no problem" to "serious problem" before surgery and 1 month, 3 months, and 6 months after surgery. A proportional odds model for the ordered multinomial response was used to compare the responses of the 2 exercise groups. RESULTS: The 2 exercise groups did not differ significantly at any postsurgical time in terms of perceived problem level from intraoral of facial pain. The difference between the 2 groups at each visit was not statistically significant for unusual sensations, although the trend was for the sensory retraining group to have a higher likelihood of reporting fewer problems. By 6 months, the likelihood of a subject reporting lower problem or interference level related to numbness or decreased lip sensitivity was significantly higher in the sensory-retraining group, approximately twice that of the opening exercise-only group. CONCLUSIONS: Our results support the premise that a simple noninvasive exercise program initiated shortly after orthognathic surgery can lessen the objectionable impression of negative altered sensations.

Congenital unilateral lower lip palsy and eventration of diaphragm.
(19/78)
Congenital unilateral lower lip palsy is a rare but well-known limited variation of congenital unilateral facial palsy. We report a three-month-old boy with diaphragmatic eventration and isolated lower lip palsy, a combination that to our knowledge, has not been described before. Probable causes of this combination of multiple congenital malformations, in this case, could be due to nonrandom and heterogeneous mutations. The diaphragmatic eventration was treated successfully.

MR imaging of labial glands.
(20/78)
BACKGROUND AND PURPOSE: The labial salivary gland is a site of occurrence of tumors and cysts, and it serves as the biopsy site for the diagnosis of Sjogren syndrome. However, its imaging features have not been well understood. Here we attempted to depict the labial gland by high-resolution MR imaging. MATERIALS AND METHODS: The labial glands from 89 patients without Sjogren syndrome, 14 patients with Sjogren syndrome, and 3 patients with tumor or cyst of the lips were imaged by using a 1.5T MR imager with a 47- or 110-mm surface coil. RESULTS: The upper and lower labial glands consisted of 1-3 layers of gland clusters, each of which had high signal intensity on T1-weighted and fat-suppressed T2-weighted images and was readily enhanced after gadolinium injection. The posterior parts of the glands were thicker than the anterior parts. The gland areas in the lower lips (186 +/- 64 mm(2) in women and 192 +/- 68 mm(2) in men) were greater than those in the upper lips (140 +/- 46 mm(2) in women and 162 +/- 66 mm(2) in men). We did not find any significant age-related changes or sex differences in the gland area. The labial gland areas were smaller in the patients with Sjogren syndrome than in patients without Sjogren syndrome, though the difference was significant only in the upper lips (104 +/- 53 mm(2)). CONCLUSION: This is the first report describing imaging features of the labial salivary glands. High-resolution MR imaging can readily delineate the labial glands. (+info)
Case of recurrent paracoccidioidomycosis in female. 10 years after initial treatment.
(21/78)
This report describes a case of recurrence of chronic paracoccidioidomycosis 10 years following the initial diagnosis. A 56-year-old female was admitted to the Dental Clinic of the Pontifical Catholic University of Parana complaining of oral soreness. Mulberry-like ulcerations were observed on the gingiva, right labial comissura, and vermillion of the lip. The patient reported persistent chronic cough, weight loss, appetite loss and fever. The anamnesis revealed that the patient had developed and been treated for paracoccidioidomycosis 10 years earlier. A biopsy was performed and microscopic examination revealed microabscesses, collections of macrophages organized into granulomas, multinucleated giant cells and Paracoccidioides brasiliensis. The patient was treated with Itraconazole and, the oral lesions disappeared within 3 months. Persistent follow-up examination in patients with a history of paracoccidioidomycosis is essential in the management of this disease. (+info)
Burning mouth syndrome: clinical profile of Brazilian patients and oral carriage of Candida species.
(22/78)
Burning mouth syndrome (BMS) is a complex disease of unknown cause. It is characterized by a burning sensation in the oral mucosa, notwithstanding its clinical normal aspect. BMS is particularly seen in postmenopausal women. The purpose of this study was to investigate this syndrome on a clinical basis and, in addition, to analyze its possible relation to the frequency of Candida species. Thirty-one patients (28 women and 3 men; 13 Caucasians and 18 non-Caucasians; mean age = 61.3, range 30-85 years) were evaluated. Most patients (80.6%) were under long-term medication, antihypertensive, ansiolitic and antidepressant drugs being the most used. Burning mouth complaint was associated with other secondary oral complaints in 83.8% of the cases. Tongue was the most commonly affected site (70.9%), followed by the vermillion border of the lower lip (38.7%) and hard palate (32.2%). The association of the burning sensation with oral cancer (cancer phobia) was reported by 67.7% of the patients. Haematologic examination (hematocrit, haemoglobin and fasting blood glucose level) revealed 2 cases each of anemia and type 2 diabetes. Local factors, tooth extractions and dentures wearing, were associated with the onset of symptoms in 35.5% of the cases. Daily activities were changed as a consequence of BMS in 29% of the patients. Among the species of the genus Candida, C. albicans was the most frequent in BMS patients (9 - 29.03%) and controls (12 - 38.70%), followed respectively by C. parapsilosis (2 - 6.45% and 0 - 0%); C. tropicalis (1 - 3.22% and 2 - 6.45%); C. krusei and C. kefyr (1 - 3.22% and 0 - 0%). Therefore, such difference did not reach valuable results. In conclusion, these data were similar to those reported in other studies. The highlights of the present findings were the possible relation of BMS with chronic drug use, depression, menopause and cancer phobia. No association was found between BMS and the prevalence of Candida species. (+info)

Nasolabial cyst: diagnostic and therapeutical aspects.
(24/78)
Nasolabial cyst is a rare lesion situated behind the ala nasi, extending backwards into the inferior nasal meatus and forward into the labio-gingival sulcus. AIM: We present our case of a nasolabial cyst, with the purpose of discussing clinical presentation, diagnosis and the more suitable surgical techniques to treat this disorder. MATERIALS AND METHODS: A retrospective study of eight patients with diagnosis of nasolabial cyst, carried out in the period of january/2000 to december/2006. The diagnosis was suggested by otorhinolaryngology exam and computer tomography. All patients were submitted to surgical treatment (enucleation) and definitive diagnosis was confirmed by histopathology. RESULTS: Predominant symptoms were nasal obstruction, swelling in the nasal vestibule region and local pain. Patients had had symptoms for a median of 26.2 months. CT scan was performed in all patients, showing a well outlined cystic lesion with bone remodeling in some cases. Median sizes of the cysts were 2.18 cm. There was no evidence of recurrence during a mean follow-up of 19.5 months. CONCLUSION: Nasolabial cysts are rare lesions. Common presentation is a well-confined swelling, local pain and nasal obstruction. Enucleation is the treatment of choice with low recurrence rate. (+info)
