[Management of orbital inflammatory disorders in internal medicine: New findings resulting from a retrospective study of 31 consecutive patients]. / Prise en charge des orbitopathies inflammatoires en médecine interne : nouvelles données issues de l'étude d'une série de 31 patients consécutifs.

PURPOSE: To describe a case series of patients investigated in internal medicine for orbital inflammation (OI) since the individualization of the clinical entity of the IgG4-related orbital disease (IgG4 ROD). PATIENTS AND METHODS: Thirty four patients were consecutively referred by a specialized center where orbital biopsy was performed when the lesion was surgically accessible. Fourteen patients were excluded in case of missing data or lymphoma, periocular xanthogranuloma or Graves' orbitopathy. Patients with systemic or auto-immune disease according to the international criteria, or presenting with idiopathic orbital inflammation syndrome (IOIS), were included. Knowing the histological similarities between IOIS and IgG4 ROD, immunohistochemical assessment of plasma cells for IgG4 positivity was performed for every patient with available biopsy. Clinical and biological characteristics, treatment and response to treatment of included patients are reported. RESULTS: Among 22 included patients, 10 presented with orbital manifestation of a systemic or autoimmune disease including 2 sarcoidosis (9%) and 8 (36%) cases of non specific OI which were reclassified in IgG4 ROD. Finally, IOIS of various clinicopathological presentation was diagnosed for 12 patients including 10 with histological documentation. Whereas relapse and resistance were not found to be related to IgG4 positivity (50% in both IOIS and IgG4 ROD groups), another treatment in addition to corticosteroids was more often necessary in IgG4 ROD patients (50%) than in IOIS patients (25%). CONCLUSION: After ruling out auto-immune orbital diseases, especially IgG4 ROD, IOIS should be discussed. Factors conditioning the corticosteroid response are yet to be determined.

[Management of orbital inflammation in internal medicine: a retrospective case series of 29 patients]. / Prise en charge de l'inflammation orbitaire en médecine interne : à propos d'une série de 29 patients consécutifs.

PURPOSE: To describe a case series of patients investigated in internal medicine for an inflammation of the orbit and to clarify the clinical and pathological features of patients with idiopathic orbital inflammatory syndrome (IOIS). PATIENTS AND METHODS: Forty patients were consecutively referred by a specialized center where an orbital biopsy was performed in case of accessible lesion. Eleven patients were excluded because of missing data or diagnosis of lymphomas, periorbital xanthogranulomas, or Graves' disease. Patients with systemic disease (SD) or auto-immune disorder (AID) that validated the international criteria, or those having an IOIS in the absence of local or systemic etiology, were included. The clinicopathologic and immunologic characteristics of IOIS patients, their treatment and their evolutionary profiles are reported according to the histological types described by Mombaerts. RESULTS: Of the 29 patients enrolled, eight had a dacryoadenitis revealing a SD/AID, mainly a necrotizing vasculitis, seven patients had a presumed IOIS and 14 an IOIS histologically documented. The presentation of IOIS was dominated by a diffuse involvement of the orbit. Corticosteroids were administered alone or with an immunosuppressant in 57 and 24% of IOIS patients, respectively. The incidence of relapse/resistance was higher than that of remission, particularly in case of presumed IOIS or in its classical form. All four patients with a stage III-IV of Chisholm were relapsing or resistant. CONCLUSION: A dacryoadenitis may reveal some types of SD/AID. Unlike the severe sialadenitis, the form of sclerosing IOIS may not be a factor associated with relapse or resistance.

[Vascular involvement in Cogan's syndrome. A case report]. / Atteinte vasculaire et syndrome de Cogan. Une observation.

Vascular manifestations of Cogan's syndrome are rarely reported. We report the case of a young woman followed for typical Cogan's disease. Serious vascular involvement was found only during work-up for arterial hypertension. This case highlights potentially asymptomatic nature of extensive vasculitis affecting large and medium-sized vessels in Cogan's disease. Careful screening is required to prevent life-threatening complications.

Conventional antihypertensive drug therapy does not prevent the increase of pulse pressure with age.

Increased pulse pressure (PP), an independent predictor of cardiovascular risk, may be quantified on the basis of the prevalence of isolated systolic hypertension (ISH) in the population at large. The purpose of this study was to estimate the prevalence of ISH and its relation to age and drug therapy in a large group of outpatient hypertensive subjects in France. Between March and December 1999, 2975 French general practitioners included 17 716 consecutive patients with uncontrolled hypertension (systolic blood pressure [SBP] >140 mm Hg and/or diastolic blood pressure [DBP] >90 mm Hg), either treated or not treated. They were asked to complete a questionnaire concerning associated cardiovascular risk factors and ongoing antihypertensive therapy. Subjects were classified according to 5 age ranges (from 18 to 103 years). In each age range, SBP, DBP, mean blood pressure, and PP were significantly lower (P<0.001) in treated subjects than in untreated subjects, with the exception of PP in subjects >75 years. The latter finding resulted from a significant increase of SBP and PP with age, together with a significant lowering of DBP with age, irrespective of drug treatment. Subsequently, the prevalence of ISH increased with age from 20.4% to 35.2% in men and women. In any given age range, drug therapy for hypertension is associated with marginally lower values of PP. In the studied populations, the increase of PP with age is independent of gender and of the presence of antihypertensive drug treatment, leading to an increased prevalence of ISH and a subsequent increase of cardiovascular risk with age.
