Solid and papillary epithelial (SPEN) is an uncommon pancreatic tumor often seen in young females. Although most of these neoplasms have a benign course, SPEN do have malignant potential. Treatment is surgical which is usually feasible either via enucleation or more radical procedures. Below we discuss diagnosis, treatment, and prognosis in detail.
OBJECTIVES: The risk of blood and body fluid exposure and, therefore, risk of blood-borne disease transmission is increased during trauma resuscitations. Use of barrier precautions (BPs) to protect health care workers (HCWs) from exposure and infection has been codified in hospital rules and in national trauma education policy. Despite these requirements, reported rates of BP compliance vary widely. The reasons for noncompliance are not known. This study assesses self-reported rates of BP usage during resuscitations among trauma professionals, explores reasons for noncompliance, and compares self-reported compliance rates with actual observed compliance rates. METHODS: A survey regarding BPs was distributed to all HCWs involved in trauma resuscitations at our Level I trauma center. All surgical and emergency medicine residents as well as attending faculty from both disciplines and nursing staff were included in this study. A total of 161 surveys were distributed and 123 were returned. RESULTS: Most HCWs (114 of 123 [93%]) reported at least one exposure (usually intact skin contact) to blood or other body fluids. A considerable variation in the type of BP used was reported for those HCWs who reported use of BPs "all of the time." Of the HCWs who reported universal use of BPs, reported usage rates were as follows: gloves, 105 of 123 (85%); eyewear (no side protectors), 58 of 123 (47%); eyewear (side protectors), 20 of 123 (16%); gowns, 22 of 123 (18%); and masks, 5 of 123 (4%). The two most common reasons for noncompliance were "time factors" (61%) and "BPs are too cumbersome" (29%). Observed compliance rates were statistically significantly lower than self-reported rates in all BPs except gloves (p < 0.02). CONCLUSION: The wide variation in BP use and the gap between perceived and actual usage that we have observed suggest that the effectiveness of current educational approaches to ensure BP use is inadequate.
BACKGROUND: As new approaches to herniorrhaphy are popularized, new complications are being encountered. Pneumomediastinum is one such complication. METHODS: We present a patient who developed pneumomediastinum after an elective bilateral preperitoneal laparoscopic hernia repair. RESULTS: The patient was observed and discharged 24 hours later with no permanent sequelae. CONCLUSION: Pneumomediastinum is a rare complication of laparoscopic hernia repair.
Complete common femoral artery transection from blunt trauma without bony injury is a rare event. Below we report upon a young cyclist who sustained complete transection of the common femoral artery following blunt trauma. The patient was managed successfully by graft repair of the transected artery. This case report highlights the importance of prompt recognition and repair of this unusual injury as well as the relationship of the injury to a previously described pattern known as motor-scooter-handlebar syndrome.
