The importance of admission physiological and biochemical variables was modeled on data from 185 patients with blunt liver trauma with regard to their significance in prediction of mortality. The variables used were admission Glasgow Coma Score, base excess (or deficit), arterial lactate, Injury Severity Score, and initial 24-hour volume of blood required for replacement. Each variable was modeled as a predictor of survival alone and in combination, using a linear logistic model. ⋯ But as a single variable reflecting the probability of death, both base excess (LD50 = -11.8 mmol/L) and initial 24-hour volume of blood (LD50 = 5.4 L) were highly significant. A combined logistic model of admission Glasgow Coma Score and base excess had the greatest likelihood of accurate prediction of outcome: P death = e lambda/l + e lambda; where lambda = -0.21(Glasgow Coma Score) -0.147(base excess) + 0.285. Testing of this predictive model on data from 323 additional patients with multiple trauma who had pelvic fracture as their index injury also showed it to be a highly significant early predictor of outcome.

Case Reports
The Budd-Chiari syndrome and hepatic veno-occlusive disease. Recognition and treatment.
In a review of 29 patients who were surgically treated by combined hepatic and portal decompression for intractable ascites, 18 were identified as falling into the category of the Budd-Chiari syndrome, with varying causes. Of this group, 2 patients were distinguished by the classical hepatic venous endophlebitis described by Chiari and later by Bras et al. ⋯ The second patient had consumed a large amount of comfrey teas, which were shown to contain high levels of pyrrolizidine alkaloids. These two cases add further weight to the existing evidence of the toxic effect of these alkaloids, and also demonstrate the effectiveness of hepatic and portal decompression.

Dampened height and weight velocities have been observed in our postburn pediatric population. To validate this phenomenon, the medical records of 80 patients who had sustained a greater than 40% total body surface area burn, were older than 2 years of age at the time of the burn, and were at least 1 year post burn were reviewed. All patients were treated with early excision of the burn wound within 72 hours of injury and received standard post burn resuscitational and nutritional support. ⋯ Despite adequate nutritional support and maximal exercise and/or long-bone stresses, a profound growth arrest was noted during postburn year 1, which slowly resolved to near normal distribution by postburn year 3. This retrospective study demonstrates that severe thermal injury is associated with a growth delay in the pediatric population. The exact cause of this phenomenon remains unknown.

Assault by burning is an often unappreciated cause of burn injury. One hundred forty-eight of 3678 adults admitted to a major burn center with acute burn injuries sustained their burns as a result of an assault by another adult. High-risk groups included blacks and alcohol abusers. ⋯ In contrast to child abuse, very few cases go to court due to the patient's failure to press charges. There was no typical burn pattern, although the injury often did not coincide with the initial medical history. The presence of multiple trauma, occurring in 16% of these patients, must be excluded in the assaulted patient.

The differential roles of infection as a microbial phenomenon and sepsis as a host response were studied in 210 critically ill surgical patients. Infections occurred in 41.4% of all cases and in 82% of nonsurviving patients. Both infection and the expression of a septic response, measured as a sepsis score, were associated with significantly increased intensive care unit morbidity and mortality. ⋯ Nonsurvivors with sepsis, on the other hand, did not differ from survivors with respect to any variable reflecting infection but did have higher mean sepsis scores. Maximum sepsis scores and sepsis scores on the day of death were similar in patients dying without infection and those dying with uncontrolled infection. The magnitude of the host septic response, independent of the presence, bacteriologic characteristics, or control of infection, is an important determinant of outcome in critical surgical illness.
