An incidental finding of carcinoid tumor of the cystic duct.

Cystic duct carcinoids are extremely rare tumors. We present a 58-year-old female with carcinoid tumor found within the cystic duct margin following laparoscopic cholecystectomy. She subsequently underwent surgical resection with a Roux-en-Y hepaticojejunostomy.

Railway train versus motor vehicle collisions: a comparative study of injury severity and patterns.

Objective: This study compares the demographics, injury severity, resource use, and injury patterns of patients involved in railway train-motor vehicle (RT-MV) to motor vehicle-motor vehicle (MV-MV) collisions.

Methods: Retrospective trauma registry review of 74 RT-MV and 1,931 MV-MV consecutive patients, age more than 14 years, presenting to two Level I trauma centers, January of 1991 to May of 1998.

Results: Compared with MV-MV, RT-MV had significantly more males (72% vs.

Retrospective analysis of the adequacy of oral contrast material for computed tomography scans in trauma patients.

Background: This study examined the adequacy of oral contrast (OC) in adult trauma patients, the differences in the incidence of pathology and other patient characteristics related to OC adequacy, and the incidence of OC-associated emesis.

Methods: The cases of 129 adult trauma patients were reviewed from January to December 1996 for utilization of OC, administration time, time to computed tomography (CT), and emesis within 4 hours. CT films were reviewed for adequacy of OC (AC = adequate contrast, IC = inadequate contrast) and pathology.

Shock index as a marker for significant injury in trauma patients.

Objective: To determine whether the shock index (SI), defined as the ratio of heart rate (HR) to systolic blood pressure (SBP), is a useful marker for significant injury in trauma patients.

Methods: A retrospective database analysis was used to relate the SI to the clinical measures: death within 24 hours, injury severity score (ISS) > or = 16, intensive care unit (ICU) stay > or = 1 day, and amount of blood transfused (BT) > or = 2 units. Consecutive trauma patients seen at one level I trauma center over a 24-month period were reviewed; excluded were patients not requiring trauma team consultation, or those with either incomplete records, severe head injury (Glasgow Coma Scale score < or = 8), or age < 14 years.

Emergency physician use of ultrasonography in blunt abdominal trauma.

Objective: To evaluate the diagnostic utility of abdominal diagnostic ultrasonography (DUS) performed by emergency physicians for intraperitoneal fluid caused by blunt abdominal trauma (BAT).

Methods: The design was a prospective, blind, observational study. During a 15-month period, a convenience sample of patients presenting to the ED with BAT necessitating CT scan of the abdomen, diagnostic peritoneal lavage (DPL), or laparotomy was studied.

Impact of a trauma system on outcome of severely injured patients.

We examined the impact of a trauma system on the survival of patients with a Trauma Score of 8 or less. We compared the observed survival with that predicted using a method that calculates the probability of survival (Ps) based on age, physiologic score, and anatomic severity of injury. Of 3394 patients triaged to trauma centers in a 12-month period, 283 (8.

Tumor-associated antigens of chemically-induced murine tumors; the emergence of MuLV and fetal antigens after serial passage in culture.

Using radioiodinated Staphylococcus aureus protein A [125I]SPA to measure syngeneic, allogeneic and heterogeneic IgG bound to murine tumor cells, we performed a serological analysis of surface antigens of 8 solid tumors and 2 leukemias of BALB/c mice (3 chemically-induced colon carcinomas, 3 chemically-induced sarcomas, 1 murine leukemia virus (MuLV) induced leukemia, 1 irradiation induced leukemia, 1 spontaneous melanoma and 1 spontaneous sarcoma). We were able to detect and distinguish between at least five separate antigenic specificities on these tumors. Unique tumor-associated antigens were found on 3 of the tumors, MuLV related antigens on 8 tumors, fetal antigens on 7 tumors and two distinct common antigens on 7 tumors (common antigen 1 (CA-1) on 5 tumors and common antigen 2 (CA-2) on 2 tumors).

Latent herpes simplex virus in the central nervous system of rabbits and mice.

Herpes simplex virus (HSV) type 1 induces a long-standing latent infection in the central nervous system of mice and rabbits. The infection was extablished in the brain stems of rabbits after corneal inoculation of the virus, and in the spinal cords of mice after rear footpad infection. In these animals, infectious virus could not be recovered by direct isolation from tissues; it was detected only after the tissues were maintained as organ cultures in vitro.
