Advanced trauma life support, 8th edition, the evidence for change.

The American College of Surgeons Committee on Trauma's Advanced Trauma Life Support Course is currently taught in 50 countries. The 8th edition has been revised following broad input by the International ATLS subcommittee. Graded levels of evidence were used to evaluate and approve changes to the course content. New materials related to principles of disaster management have been added. ATLS is a common language teaching one safe way of initial trauma assessment and management.

Plasma pituitary hormone levels in severe trauma with or without head injury.

In order to evaluate the effect of head injury in severely traumatized patients on the response of ACTH, GH, PRL, and TSH plasma levels, 36 patients were prospectively studied over 5 consecutive days following injury. They were divided into three groups: Group I, severe isolated head injury (n = 14); Group II, multiple injury combined with severe head injury (n = 12); Group III, multiple injury without head injury (n = 10). No significant trend was observed during the 5 consecutive days. The following changes in plasma levels were observed, compared to normal reference value (median values): ACTH was normal in the three groups; PRL was elevated in Group II and normal in the other groups; GH was elevated in all groups; TSH was elevated in Group III and reduced in Groups I and II. Intergroup comparisons showed significantly lower plasma levels for PRL (p less than 0.05) and TSH (p less than 0.01) in Groups I and II, i.e., head-injured patients, compared to Group III, i.e., traumatized patients without head injury. A relationship was observed between the severity of head injury, as expressed by Glasgow Coma Score, intracranial pressure levels, outcome, and TSH and PRL levels.

OCT e índices de insulinorresistencia en diabéticos tipo 2 no insulinodependientes sin signos de retinopatía

A una població de diabètics tipus 2 no insulinodepenents i sense signes clínics de retinopatia diabètica, realitzem un estudi de la possible relació entre índexs indirectes d’insulinorresistència i troballes de tomografia de coherència òptica de gruix macular y de gruix de la capa de fibres nervioses de la retina peripapil•lar. La nostra hipòtesi consisteix en valorar el possible dany neurodegeneratiu previ a les alteracions microvasculars clàssiques sobre la retina a aquesta malaltia i estudiar la seva possible relació amb la insulinorresistència.

Copper, selenium, and zinc status and balances after major trauma.

To investigate the trace elements (TE) losses and status after trauma, 11 severely injured patients (Injury Severity Score: 29 +/- 6), admitted to the ICU were studied from the day of injury (D0) until D25. Balance studies were started within 24 hours after injury, until D7. Serum and urine samples were collected from D1 to D7, then on D10, 15, 20, and 25. Intravenous TE supplementation was initiated upon admission. SERUM: Selenium (Se) and zinc (Zn) levels were decreased until D7 and were normal thereafter. LOSSES: TE urinary excretions were higher than reference ranges until D20 in all patients. Fluid losses through drains contained large amounts of TE. BALANCES: Balances were slightly positive for copper (Cu) and Zn, and negative for Se from D5 to D7 despite supplements. Cu status exhibited minor changes compared to those observed with the Zn and Se status: Serum levels were decreased and losses increased. Considering the importance of Se and Zn in free radical scavenging, anabolism, and immunity, current recommendations for TE supplements in severely traumatized patients ought to be revised.

Acute and usual drinking among emergency trauma patients: a study on alcohol consumption and injury patterns.

OBJECTIVE: To investigate the relationship between usual and acute alcohol consumption among injured patients and, when combined, how they covary with other injury attributes. METHODS: Data from a randomised sample of 486 injured patients interviewed in an emergency department (Lausanne University Hospital, Switzerland) were analysed using the chi(2) test for independence and cluster analysis. RESULTS: Acute alcohol consumption (24.7%) was associated with usual drinking and particularly with high volumes of consumption. Six injury clusters were identified. Over-representations of acute consumption were found in a cluster typical of injuries sustained through interpersonal violence and in another formed by miscellaneous circumstances. A third cluster, typical of sports injuries, was linked to a group of frequent heavy episodic drinkers (without acute consumption). CONCLUSIONS: Among injured patients, acute alcohol consumption is common and associated with usual drinking. Acute and/or usual consumption form part of some, but not all, injury clusters.

La violence ou le traumatisme médical dans une consultation pluridisciplinaire spécialisée [Violence our medical trauma in specialized multidisciplinary consultation].

In this article a particular patient/physician relationship is described and analyzed: The described interaction between patient and physician during a consultative investigation by several specialists differs markedly from the common trustful relation between a patient and his family doctor. In this context the term and phenomenon pain is discussed and the necessity for an understandable, patient-oriented presentation of diagnosis and hypotheses considering the patient's individual bio-psycho-social dimension is stressed. Consequences for student education are mentioned.

Pancreatic trauma in children.

We identified two distinct groups of patients in the 91 documented cases of pancreatic trauma (median age 8.0 years, range 0.6-15.8 years; M:F 2.5:1.0): 59 had a history of abdominal trauma and elevated serum lipase but no CT or ultrasound evidence of pancreatic injury (Group A); 32 had a history of abdominal trauma, elevated serum lipase but also had CT scan and/or ultrasound evidence of pancreatic injury (Group B). Patients with "less severe" injury based on normal imaging had a lower initial lipase level [Group A, median 651 U/L (interquartile range 520-1,324) vs. Group B, 1,608 U/L (interquartile range 680-3,526); p = 0.005] and shorter admission time [Group A, 9.0 days (interquartile range 5.5-15.5) vs. Group B, 13.4 days (interquartile range 6.8-23.8); p = 0.04]. There were no differences with respect to mortality (Group A, 13.5% vs. Group B, 12.5%), but patients with evidence of injury on imaging were more likely to have surgical intervention (p = 0.0001). The single most important overall cause of pancreatic trauma was involvement in a motor vehicle accident as a passenger or pedestrian. However, in children with high-grade ductal injury, bicycle handlebar injuries were most common. Associated injuries were common in both groups.

Cell Therapy Assistance in Reconstructive Surgery for Musculoskeletal Tissues Following Burn and Trauma: Swiss Cellular Transplantation Platform

The sterol compositions of three oceanic jellyfish have been determined using gas chromatographic mass spectrometric techniques involving the use of two separate gas chromatographic column systems. The components in overlapping peaks have been identified by comparison of the mass spectra of peaks in the two column systems using subtractive techniques. A mid-water animal, Periphylla periphylla, was found to contain a very complex and unusual sterol profile including rare 5alpha-stanols, whereas two other oceanic jellyfish Pelagia noctiluca and Atolla wyvillei contained similar mixtures of delta5 sterols to those previously isolated from coastal species.

Traumatic mitral valve injury after blunt chest trauma: a case report and review of the literature.

Mitral valve injury after blunt chest trauma is a rare occurrence. We recently admitted a patient with severe traumatic mitral regurgitation who was successfully treated with surgery. Review of the literature aimed at taking an inventory of cases of traumatic nonpenetrating mitral insufficiency that were operated on, since the earliest report in 1964. Eighty-two cases were found and analyzed allowing for a better understanding of the epidemiology, etiology, natural history, pathology, and treatment of this rare condition. The most common lesions reach the papillary muscles (PM), followed by the chordae and then the mitral valve leaflets. Among the 82 cases reported that have been treated with surgery, 57% required a valve replacement. More than half of the patients had a PM injury with a complete or partial rupture. When the rupture is complete, and especially when it involves the anterior PM, the clinical picture is most always acute with clinically important hemodynamic repercussions, often necessitating emergency surgery, most of the time with mitral valve replacement. One must always suspect traumatic mitral injury after blunt chest trauma. The most common mitral lesions affect the PM. The clinical course can be indolent or devastating, and most often requires urgent or delayed surgical treatment, either with mitral valve repair or replacement.

Der 11. September aus der Sicht eines Schweizer Trauma Fellows in New York [September 11 from the viewpoint of a Swiss trauma fellow in New York]

This is the report of the events of September 11th seen through the eyes of a Swiss Trauma Fellow. This ill-fated day is described by someone who went down to ground zero with other doctors to help and save lives and came back frustrated because there was so little to be done.
