Spontaneous bladder rupture after non-traumatic vaginal delivery: a rare case report.

Spontaneous bladder rupture (SBR) is a rare condition and often missed diagnosis, especially after a non traumatic vaginal delivery. A 32-year-old para 3 woman, consulted for abdominal pain and anuria two days after instrumental vaginal delivery with forceps for foetal distress in second sate of labour. Blood tests were suggestive of an acute renal failure.

A Novel Approach for Powder Bed Fusion of Ceramics Using Two Laser Systems.

The one-step AM process is considered the goal many researchers seek in the field of Additive Manufacturing (AM) of high-technology ceramics. Among the several AM techniques, only Powder Bed Fusion (PBF) can directly print high-technology ceramics using one step. However, the PBF technique faces numerous challenges to efficiently be employed in the PBF of ceramics.

Congenital Epulis Diagnosed Antenatally.

Congenital epulis is a benign gingival tumor whose differential diagnosis includes other oral-facial masses such as teratoma, hemangioma, lymphatic malformation and dermoid cysts. This tumor can cause obstruction of the airway or feeding problems in the newborn. Surgical excision is the treatment of choice.

Multi-Layer Simulation of the Powder Bed Selective Laser Processing of Alumina for Residual Stress and Distortion Evaluation.

A numerical model was developed to simulate the real process of alumina powder bed selective laser processing (PBSLP) to thoroughly investigate the residual stress and distortion experienced in printed parts when multi-layer scanning with a CO laser source is considered. The model contains a user-defined function (UDF) for the laser source, temperature-dependent material properties, scanning strategies, and build orientations, and it is solved using ANSYS 2020R2. In addition, the model's validation was confirmed with experimental results.

Compound blue nevus: A misleading pigmented melanocytic tumor.

Compound blue nevus had clinical and histological similarities with other heavily pigmented melanocytic tumor, like the pigmented epithelioid melanocytoma. Distinctive genomic aberrations have allowed differentiating it. The defining characteristic of blue nevi family is the presence of activating mutations in the G protein α-subunits, GNAQ and GNA11.
