Comparative Study
Comparison of wound infection rates using plain versus buffered lidocaine for anesthesia of traumatic wounds.
Buffered lidocaine has been shown to be less painful than plain lidocaine for anesthetizing wounds. However, the effect of a buffering agent on the local host defenses has not been evaluated. The infection rates of wounds anesthetized with plain lidocaine versus buffered lidocaine were compared in an observational cohort study. ⋯ The infection rate for patients treated with plain lidocaine was 3.5%, versus that for patients treated with buffered lidocaine, 3.9% (P = .63). After adjustment for confounding variables, the infection rate did not differ between plain and buffered lidocaine. The infection rates of wounds repaired after anesthesia with either plain or buffered lidocaine are similar.

Case Reports
Traumatic thrombophlebitis of the superficial dorsal vein of the penis: an occupational hazard.
Several cases of thrombophlebitis of the superficial dorsal vein of the penis (TSDVP) have been reported in the literature. Etiologies may include any of the following: trauma associated with vigorous sexual intercourse; penile strangulation caused by a multitude of entities; penile injection; infection; neoplasm; or surgery. We report a rare case of traumatic TSDVP in a cab driver following repeated injury to the penis by a coin-filled pouch. We review the etiologies, mechanism, and treatment of traumatic TSDVP, and attempt to identify men who may be at similar occupational risk.

Case Reports
Spontaneous cervicothoracic epidural hematoma following prolonged valsalva secondary to trumpet playing.
Spontaneous spinal epidural hematoma is an uncommon clinical entity. Patients with this disease may present with devastating neurological deficits that can mimic other diseases. Emergency physicians should be familiar with this condition to assure appropriate therapy in a timely manner. A typical case of spontaneous spinal epidural hematoma is presented with review of appropriate differential diagnosis and management.
