BACKGROUND: Implant rupture is one of the complications of breast augmentation surgery. The rupture of silicone implants is often insidious, potentially causing problems at any time. This is a case report of the rupture of 145-cc breast implants manufactured by Dow Corning Corporation and their removal at 40 years after augmentation. CASE PRESENTATION: A 70-year-old female patient was admitted for the removal of a lump in the upper and inner quadrants of the right breast. After a detailed examination, a rupture of the bilateral breast implants was diagnosed. Explantation without replacement was performed; the entire procedure proceeded smoothly. Immunohistochemical staining revealed siliconoma with lymphoid hyperplasia and calcification in the bilateral breasts with no signs of malignancy. CONCLUSIONS: Silicone breast augmentation is one of the most popular aesthetic surgical procedures worldwide. Therefore, it is important to educate patients on the need for close monitoring of their implants after augmentation through magnetic resonance imaging or ultrasound to facilitate early detection of any changes before a rupture occurs. Early detection of the implant rupture, in turn, will facilitate early and effective management.

The achiral 2,6-bis(imidazol-1-yl)pyridine (L) was used as the ditopic organic tecton for the formation of coordination polymers with Zn(II) ions. Hydrothermal reaction between L and ZnX2 (X=Br, Cl) afforded spontaneous resolved double helical motifs in ZnLCl2.0.5H2O (1) and ZnLBr2.0.25H2O (2). In the homochiral crystals of 1a and 2a, the helices are of M-helicity, whereas, in 1b and 2b, they are of P-helicity. In contrast, solvothermal reaction between L and ZnCl2 in dried DMF afforded achiral ZnLCl2 (3a), which exhibits a zigzag polymeric motif. An achiral polymorph 3b which contains 21 helical chains was obtained in wet DMF. The formation of different 1D motifs was related to the conformations of L. All these compounds were characterized by infrared spectroscopy, elemental analyses, and single-crystal X-ray diffraction. As revealed by thermal gravimetric analysis and powder X-ray diffraction study, the homochiral motif in 1 was stable even upon removal of guest water molecules. Contrastingly, structural transformation from 3a or 3b to 1 is possible upon hydration.
