statement of the problem: one disadvantage of cement-retained crowns is the lack of predictable irretrievability. this problem can be overcome through designing a screw access hole in the metal substructure of cement-retained restoration and using porcelain stain to define this area. purpose: this study aimed to evaluate the influence of existence of screw access hole on porcelain fracture resi...

The retained placenta is a significant cause of maternal mortality and morbidity throughout the developing world. It complicates 2% of all deliveries and has a case mortality rate of nearly 10% in rural areas. Ultrasound studies have provided fresh insights into the mechanism of the third stage of labour and the aetiology of the retained placenta. Following delivery of the baby, the retro-place...

Background: A 36-year-old male presented to the emergency department with a 4-day history of vomiting, loss of appetite and gastric pain radiating to the back. He denied fever and diarrhea. His medical record includes a Billroth-II procedure in another hospital for gastric lymphoma in 1992, hepatitis C and ferriprive anemia. Vital signs in the emergency department were normal.

Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient’s expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds ...

This report documents two instances of retained flexible ureteroscopes at the time of ureteroscopy and laser lithotripsy in a healthy 37-year-old male and a 53-year-old male with a pelvic kidney. We describe maneuvers to remove the ureteroscope endoscopically in the first case, while the second case required conversion to open surgery for ureteroscope extrication.

transformation induced plasticity (trip) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. these characteristics of tripsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deformation. the microstr...

Intra-abdominal retained surgical sponge is an uncommon surgical error. Herein, we report a 92-year-old woman who was brought to the emergency room for acute urinary retention. She had a history of vaginal hysterectomy for uterine prolapse 18 years previously, performed at our hospital. Retained surgical sponge in the pelvic cavity was suspected by abdominal computed tomography. The surgical ga...
