The ductal stretching technique: an endoscopic-assisted technique for removal of submandibular stones.

Objective: The purpose of this study was to describe an innovative surgical technique for the removal of posterior and hilar stones of the submandibular salivary duct.

Huge Renal Arteriovenous Malformation Mimicking a Simple Para-Pelvic Cyst

The presenting symptoms of renal arteriovenous malformation are usually gross hematuria and hypertension. Herein we present an unusual case of a huge renal arteriovenous malformation without these signs, but with an ultrasound picture mimicking a simple para-pelvic cyst. Other imaging tests, including duplex ultrasound, computerized tomography and aortography, demonstrated the vascular lesion. We suggest that duplex ultrasound should accompany routine renal ultrasound in order not to miss such cases, especially when the physical examination suggests an intra-abdominal vascular lesion or bleeding.

A New Role of Vemurafenib as a Neoadjuvant Treatment of Axillary and Brain Melanoma Metastases

Vemurafenib is approved by the FDA for the management of unresectable or metastatic melanoma. However, its role as a neoadjuvant therapy has not been determined. We present the first documented case in which vemurafenib induced complete tumor necrosis of both lymph node and brain metastases within one month or less, an outcome that indicated that the patient was a good candidate for excisional surgery.

Evaluation of a Porcine Dermal Collagen (Permacol) Implant for Abdominal Wall Reconstruction in a Pediatric Multitrauma Patient

The presence of a contaminated surgical field in abdominal wall defects caused by trauma presents a challenge for surgeons. Both primary suture and synthetic meshes are strongly discouraged as surgical treatments in such cases. We describe the use of a porcine dermal collagen (Permacol) implant in an eight-year-old patient with multiple injuries. Three months after discharge, the child remains well with good cosmetic results. He is free of pain and has returned to full activity levels with complete wound closure and without any evidence of residual hernia. In conclusion, our experience indicates that the use of Permacol can be considered an efficient technique for reconstructing an infected abdominal wall defect of a pediatric multitrauma patient.
