Tuberculosis of the breast: an uncommon presentation of an old disease.

Breast tuberculosis (TB) is considered an uncommon disease with an estimated incidence of 0.1% of all breast lesions reported in developed countries. A 53-year-old Caucasian woman, with a medical history of Crohn's disease, previously treated with infliximab for 3 months suspended due to a presumptive diagnosis of TB for which antitubercular regimen was started. Five months after, a painful lump in the left breast was identified by the patient. Mammary ultrasound confirmed left breast nodules and axillary adenopathies. Histology and microbiology of both lesions confirmed breast TB. Molecular drug susceptibility testing in both samples revealed no resistance to first line anti-TB drugs and the regimen was maintained for 1 year, with clinical and radiological improvement. Mammary gland involvement usually results from lymphatic extension and differential diagnosis frequently includes breast cancer or bacterial abscess.

Graves Lower Eyelid Retraction.

PURPOSE: Graves lower eyelid retraction (GLLR) is a common and controversial sign of Graves orbitopathy. The authors reviewed the mechanisms and surgical techniques currently used to correct this Graves orbitopathy-related eyelid malposition. METHODS: A literature search was performed on the MEDLINE database using the keywords "lower eyelid retraction," "Graves orbitopathy," "thyroid ophthalmopathy," "thyroid eye disease," "spacers," and "eyelid surgery." Only articles in English were included. The level of evidence of publications regarding surgical correction of GLLR was evaluated and graded from I to IV, using a rating system adapted from a validated scientific evidence classification method. RESULTS: The mechanisms responsible for GLLR are not fully understood and no subtypes of GLLR have been distinguished. The surgical literature of GLLR encompasses mainly descriptions of surgical techniques without objective measurements of the results, and uncontrolled studies. Only 1 randomized controlled trial was identified. To lengthen the lower retractors, a large variety of different materials have been used as spacers. CONCLUSIONS: The scientific literature on GLLR is vast, however controlled and randomized studies comparing different surgical techniques are lacking. At the present moment it is not clear if bioengineered materials are superior to conventional autogeneous tissue as lower eyelid spacers. The effects of GLLR on lower eyelid movements and contour have not been studied.
