A pen as an intermediate target becomes a secondary projectile.

Firearm projectiles striking intermediate targets have the potential to create secondary projectiles, which can produce identifiable patterns of injury. We present a case in which a father, manipulating a handgun, was demonstrating how the firing pin worked to his adolescent son. He placed a pen inside the barrel of the gun for demonstration but did not recognize that a bullet was loaded into the firing chamber.

Hyperoxalosis Secondary to Intravenous Vitamin C Administration as a Non-Allopathic Treatment for Cancer.

Vitamin C (ascorbic acid) has long been known to have antioxidant properties, with associated claims that it can boost the immune system, fight off infection, and help in the treatment of cancer. Similar to many other over-the-counter and herbal medicines, vitamin C can cause potential side effects with significant morbidity and rarely mortality. We discuss a case of an elderly woman with metastatic adenocarcinoma of the lung that was treated with several rounds of allopathic chemotherapy; however, treatment was stopped because of worsening quality of life and disease progression.

Forensic Radiology Pitfalls: CT Imaging in Gunshot Wounds of the Head.

Computed tomography (CT) imaging is increasingly used in emergency departments and trauma services and is being offered as a supplemental tool with autopsy in coroner's and medical examiner's offices throughout the United States. The availability of CT images in lieu of traditional X-rays for medicolegal autopsies may lead to misinterpretation of images for forensic pathologists who are not familiar with these types of images. Forensic pathologists must become familiar with CT imaging, the basis of CT image formation and how to interpret CT images appropriately.
