Cutting Parameter Selection for Efficient and Sustainable Repair of Holes Made in Hybrid Mg⁻Ti⁻Mg Component Stacks by Dry Drilling Operations.

Drilling is one of the most common machining operations in the aeronautic and aerospace industries. For assembling parts, a large number of holes are usually drilled into the parts so that they can be joined later by rivets. As these holes are subjected to fatigue cycles, they have to be checked regularly for maintenance or repair, since small cracks or damage in its contour can quickly cause breakage of the part, which can have dangerous consequences.

Laparoscopic resection of adrenal teratoma.

Background: Teratoma is a germ-cell tumor that commonly affects the gonads. Its components originate in the ectoderm, endoderm, and mesoderm. Extragonadal occurrence is rare.

A rare complication associated to a suprapubic cystostomy: catheter knotting.

We report a rare case of spontaneous catheter knotting in the setting of a suprapubic cystostomy and also review previous reports and the rationale behind this event.

Laparoscopic partial cystectomy in the management of bladder endometriosis: report of two cases.

Endometriosis is the proliferation of endometrial tissue outside the normal confines of the myometrium or uterine cavity. Endometriosis involving the urinary tract occurs in approximately 1% to 2% of cases. The bladder is affected in 80% of these patients.
