[Use of stereotaxic aspiration macrobiopsies in managing breast microcalcifications: first series of 115 prospective cases]. / Apport des macrobiopsies stéréotaxiques par aspiration dans la stratégie de prise en charge des microcalcifications mammaires: première série prospective de 115 cas.

UNLABELLED: The objective of this prospective study of a 115-case series cases was to delineate the specific usefulness of this technique for the diagnosis and management of patients with microcalcifications. MATERIALS AND METHODS: Patients with probably benign ACRII and III (n = 87) or suspicious ACRIV (n = 14) and high suspicious lesion ACRV (n = 7) lesions. The microcalcification sites were blopsied with a dedicated table and a vacuum assisted aspiration system (Mammotome). The results were correlated either with the results of any surgery or, for the lesions with benign histology findings, with the results of the six-month follow-up mammography. RESULTS: These results concern a series with a follow-up longer than one year. The patients' mean age was 53 years. The procedure was possible in 108 of 115 cases (feasibility). There were two failures. We studied 87 patients with ACRII or III findings; the mean size of the microcalcification cluster was 8.3 +/- 6 mm. For 67, it was less than or equal to 10 mm. The mean size for the 21 patients initially staged as ACRIV or V was 18 +/- 9 mm, and for 15 of them, it was less than or equal to 10 mm. Microcalcifications were found on the radiographs of 96% of the biopsies specimens. Excision was complete in 59 of 73 cases for the clusters less than or equal to 10 mm and in only 12 of 35 cases for the larger clusters. The correlation between the ACR staging and the histology results was excellent. CONCLUSION: Vacuum-aspirated biopsies are indicated especially among patients with an ACRIII finding and a cluster smaller than 10 mm. Surgery was avoided in more than 60% of these cases. When surgery was performed, it most often resulted in the discovery of malignant lesions. This procedure was also useful for the very small ACRIV clusters, which were totally benign and completely excised. Finally it can be useful for obtaining a preoperative diagnosis in the case of extensive ACRIV or ACRV lesions (strategic biopsies).

Aortitis with antiphospholipid antibodies: CT and MR findings.

Two cases of aortitis associated with the presence of antiphospholipid antibodies (APAs) are reported. Only CT and MR imaging were able to show these unusual form of aortitis preferentially affecting the outer aortic tunics. We conclude that aortitis could be a new manifestation of primary antiphospholipid syndrome (APS) and the initial pathological process before the development of aortic thrombosis, reported as a classical complication of APS.

[Mesenteric lymph node cavitation disclosing celiac disease in adults]. / Cavitation ganglionnaire mésentérique révélatrice de maladie coeliaque chez l'adulte.

We report a case of cavitation of the mesenteric lymph nodes, an uncommon complication of celiac diseases. Computerized tomography is the method of choice for diagnosis and follow up after gluten free diet.

[Malignant hyperthermia in ophthalmologic surgery]. / L'hyperthermie maligne dans la chirurgie ophtalmologique.

Malignant hyperthermia is a potentially fatal complication of general anesthesia that may occur with greater frequency in ptosis and strabismus surgery. The case of a two-year-old girl who suffered a malignant hyperthermia crisis during strabismus surgery is reported. The pathophysiology, clinical features, treatment and pre-anesthetic diagnosis are reviewed in detail.
