Oral involvement in sarcoidosis: report of 12 cases.

AIM: To assess the clinical features, treatment and outcome of oral sarcoidosis and to determine whether oral involvement is associated with a particular clinical phenotype of sarcoidosis. DESIGN: Multicentric retrospective study. METHODS: Retrospective chart review. Each patient was matched with four controls. RESULTS: Twelve patients (9 women, 3 men) were identified. Their median age at sarcoidosis diagnosis was 38 years. Oral involvement was the first clinical evidence of sarcoidosis in seven cases and was a relapse symptom in five cases. Clinical presentations were nodules (n = 7) or ulcers (n = 5) and were mostly solitary. The tongue was the commonest site affected (n = 4), followed by lips (n = 3), oral mucosa (n = 2), palate (n = 2) and gingiva (n = 1). Patients with oral sarcoidosis were significantly younger and had more frequent lacrimal or salivary glands and upper airway tract clinical involvement than the controls; increased angiotensin-converting enzyme was less frequent in oral sarcoidosis. Multiple treatments of oral sarcoidosis were used: no treatment (n = 3), surgery (n = 2), corticosteroids (n = 7), hydroxychloroquine (n = 3), methotrexate (n = 2), doxycycline (n = 1). Methotrexate was efficient in one patient, hydroxychloroquine showed benefit in only 1 out of 3 patients. Three patients presented oral relapses. After a mean follow-up of 6 years, 10 patients experienced a complete (n = 7) or partial (n = 3) remission of oral sarcoidosis; stability was observed in the remaining two cases. CONCLUSION: Although oral manifestations of sarcoidosis are unusual, physicians should be aware that this specific localization is frequently the first manifestation of the disease. Treatment modalities range from observation in asymptomatic patients to immunosuppressants for severe involvement.

[Efficiency of imatinib in polyserositis revealing a FIP1L1-PDGFRA-negative hypereosinophilic syndrome]. / Efficacité de l'imatinib au cours d'un syndrome hyperéosinophilique FIP1L1-PDGFRA négatif révélé par une polysérite.

INTRODUCTION: Hypereosinophilic syndromes rarely manifest as polyserositis. Imatinib mesylate is the reference treatment for myeloid variants of FIP1L1-PDGFRA-positive hypereosinophilic syndromes. A response to imatinib has also been reported in FIP1L1-PDGFRA-negative hypereosinophilic syndromes. CASE REPORT: We report a 25-year-old man who presented with a FIP1L1-PDGFRA-negative hypereosinophilic syndrome, with severe pericardial effusion and bilateral pleuritis. Imatinib mesylate at the dose of 100mg daily was started because of high-dose corticosteroids dependence. A response was noted after 15 days of treatment. Corticosteroids were discontinued after 7 months and the patient remained asymptomatic after 23 months of treatment. CONCLUSION: This report evidences the association of polyserositis with hypereosinophilic syndromes and the potential efficacy of imatinib mesylate even in FIP1L1-PDGFRA-negative patients.

[Interest of an internist's consultation in uveitis. Comparative study in 66 cases]. / Apport de la consultation interniste dans le diagnostic étiologique des uvéites. Etude comparative portant sur 66 patients.

BACKGROUND: After exclusion of a masquerade syndrome, uveitis may be associated with infection, systemic diseases, specific ocular diseases, or may be drug-induced. In order to improve diagnostic strategy in uveitis, we performed a comparative study to assess the importance of internist and ophtalmologist's collaboration and we proposed a well-adapted diagnostic procedure. MATERIAL AND METHODS: A comparative study was performed in a tertiary centre. The population was divided in two groups. The first one was retrospective and consisted of patients treated at the Ophthalmology department of Croix Rousse Hospital from 1991 to 2002 without internist's collaboration. The second one was prospective and consisted of patients referred in the same centre in 2003 and 2004 with intervention of an internist. Patients of less than 18 years of age with pre-existent diagnosis, specific ocular diseases, toxoplasmosis infection, or with human immunodeficiency virus infection were excluded. RESULTS: Sixty-six patients were included. Anterior uveitis was the most frequent form (25 cases), followed by panuveitis (20 cases), posterior uveitis (14) and intermediate uveitis (7). The most frequent cause of uveitis was systemic disease (19 cases) followed by infection (7 cases) and neurological entities (4 cases). The rate of diagnosis was 30.3% without internist's intervention and 60.6% when patients were referred to an internist (P=0,01). The internist intervention was contributive in 75% of diagnoses. CONCLUSIONS: The internist intervention significantly enhances the rate of etiological diagnoses in uveitis. These results should further strengthen the internist/ophthalmologist collaboration for patients with uveitis.

Necrotizing gastritis due to Bacillus cereus in an immunocompromised patient.

Bacillus cereus is increasingly being acknowledged as a serious bacterial pathogen in immunocompromised patients. We present a case of acute necrotizing gastritis caused by B. cereus in a 37-year-old woman with acute myeloblastic leukemia, who recovered following total parenteral nutrition and treatment with imipenem and vancomycin. B. cereus was isolated from gastric mucosa and blood cultures. Up to now, no case of acute necrotizing gastritis due to this organism has been reported.
