Cinnamon-induced Oral Mucosal Contact Reaction.

Contact stomatitis associated with consumption of cinnamon flavoring agents is a relatively uncommon disorder. Of relevance, both clinical features and the histopathologic findings of this condition are nonspecific, and, more importantly, may resemble some other inflammatory oral mucosa disorders, eventually making diagnosis difficult. Usually a patient exhibits a combination of white and erythematous patches of abrupt onset, accompanied by a burning sensation.

Rhabdomyomatous (mesenchymal) hamartoma presenting as haemangioma on the upper lip: a case report with immunohistochemical analysis and treatment with high-power lasers.

Rhabdomyomatous hamartoma is a rare disease that occurs predominantly in the skin. This paper describes a congenital lesion in a 17-year-old male, who came to our clinic presenting a circumscribed swelling involving the oral mucosa and vermillion border of the upper lip, purplish in color, and blanching under pressure. The patient reported that he had had lesion since his birth.

Lip and oral venous varices treated by photocoagulation with high-intensity diode laser.

Lip and oral venous varices are acquired benign vascular lesions characterized by a darkblue to violaceous papule or nodule, commonly found on the ventral tongue and lower lip. Although these lesions are usually asymptomatic, they can bleed if injured. This study assessed the effectiveness of photocoagulation with high-intensity diode laser in the treatment of these lesions.

Rapid progression of an idiopathic leukoplakia to a proliferative verrucous leukoplakia lesion and then squamous cell carcinoma.

The article reports a case of oral proliferative verrucous leukoplakia (OPVL) in a 76-year-old woman, underscoring how an otherwise inconspicuous white plaque lesion can rapidly turn into a phase of verrucous carcinoma and subsequently squamous cell carcinoma.

Oral mucocele of unusual size on the buccal mucosa: clinical presentation and surgical approach.

Oral mucoceles are small-size, benign minor salivary gland pathologies. The most frequent localizations of these lesions are the lower lip mucosa. However, in some cases, they grow to an unusual size and hinder the preliminary diagnosis of mucocele.

Lichenoid reaction to carbamazepine in the oral mucosa: case report.

Lichenoid drug reactions are more common in skin, but they may also occur in the oral mucosa. It is difficult to diagnose these lesions due to their clinical similarity to the idiopathic oral lichen planus lesions. The present article reports a case of lichenoid reaction in oral mucosa associated to the use of carbamazepine, emphasizing the diagnostic process.

Extensive amalgam tattoo on the alveolar-gingival mucosa.

Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity.

Acupuncture for the prevention of radiation-induced xerostomia in patients with head and neck cancer.

The aim of this study was to evaluate the effectiveness of acupuncture in minimizing the severity of radiation-induced xerostomia in patients with head and neck cancer. A total of 24 consecutive patients receiving > 5000 cGy radiotherapy (RT) involving the major salivary glands bilaterally were assigned to either the preventive acupuncture group (PA, n = 12), treated with acupuncture before and during RT, or the control group (CT, n = 12), treated with RT and not receiving acupuncture. After RT completion, clinical response was assessed in all patients by syalometry, measuring the resting (RSFR) and stimulated (SSFR) salivary flow rates, and by the visual analogue scale (VAS) regarding dry mouth-related symptoms.

Analysis of a possible association between oral lichen planus and drug intake. A controlled study.

Objectives: To investigate whether daily systemic and/or topical medication contributes to the development of oral lichen planus (OLP) lesions.

Study Design: The study involved 110 OLP patients and 76 control subjects, matched by age, race and sex. The analyzed data included medical records, drug intake and topical medication.

Venous lake of the lips treated using photocoagulation with high-intensity diode laser.

Objective: To evaluate the effectiveness of photocoagulation with high-intensity diode laser in the treatment of venous lake (VL) lesions.

Background Data: VL is a common vascular lesion characterized by elevated, usually dome-shaped papules, ranging in color from dark blue to dark purple, seen more frequently in elderly patients. They often occur as single lesions on the ears, face, lips, or neck.

Double-blind, crossover, placebo-controlled clinical trial with clobetasol propionate in desquamative gingivitis.

The aim of this study was to evaluate the efficacy of a 0.05% clobetasol propionate ointment administered in trays to 22 patients with desquamative gingivitis in a double-blind, crossover, placebo-controlled trial. Patients received container number 1 and were instructed to apply the ointment 3 times a day for 2 weeks, and to reduce the application to once a day in the third week.

Systemic treatment in severe cases of recurrent aphthous stomatitis: an open trial.

Purpose: This study aimed to evaluate the efficacy of the systemic drugs thalidomide, dapsone, colchicine, and pentoxifylline in the treatment of severe manifestations of RAS.

Methods: An open, 4-year clinical trial was carried out for 21 consecutive patients with severe RAS. Initially, patients were given a 2-week course of prednisone to bring them to a baseline status.

Oral lesions in 166 patients with cutaneous psoriasis: a controlled study.

Objectives: This study was aimed to test if the frequency of oral lesions bears statistical correlation or not with the condition of cutaneous psoriasis.

Study Design: Two groups were examined, one made up of 166 patients with skin psoriasis and the other with the same number of individuals with a negative history of skin diseases (control group), matched by age, race, and sex. Patients with psoriasis were grouped according to their having localized or generalized forms of the disease.

Mast cell concentration in the wound healing process of incisions made by different instruments.

The aim of this study was to compare the concentration of mast cells (MCs) in the healing process of incisions. Thirty rats were submitted to six linear incisions each, performed in the dorsal skin by carbon dioxide (CO(2)) and diode lasers, electrocautery and conventional scalpel. The animals were euthanized at intervals of 0 h, 24 h, 48 h, 72 h, 7 days and 14 days after the incisions had been made.

Risk factors for oral squamous cell carcinoma in young and older Brazilian patients: a comparative analysis.

Objectives: The aim of this study was to investigate risk factors and clinical aspects associated with oral squamous cell carcinoma (OSCC) in young patients as compared to older ones. STUDY DESIGN. Data was obtained by retrospective analysis of files of patients with OSCC, who were categorised into two groups: the young group (< or =40 years old) and the older group (> 40 years old).

Quality of life in patients submitted to surgical treatment for minor salivary gland neoplasms.

This study was aimed at assessing the quality of life in patients submitted to surgical treatment for minor salivary gland neoplasms (MSGN). Twelve patients (10 women and 2 men, mean age: 49.4 years) with histopathologic diagnosis of pleomorphic adenoma (PA, 3 cases), polymorphous low-grade adenocarcinoma (PLGA, 2 cases), cystic adenoid carcinoma (CAC, 4 cases), and muco-epidermoid carcinoma (MEC, 3 cases) were evaluated.
