The results of anthelmintic-abbreviated infections of Trichostrongylus colubriformis and Teladorsagia circumcincta on fecal egg counts in goats on pasture.

Twenty, 2-yr-old angora goats kept on nematode larvae-contaminated pasture since birth were divided into 2 equal groups. Goats from group 1 were immunized by drug-abbreviated infection, a procedure that gave high protection against field challenge in 12-moold sheep. Group 1 was orally dosed 3 times with increasing numbers of Trichostrongylus colubriformis and Teladorsagia circumcincta infective larvae. Each time, the infection was abbreviated with Oxfendazole (OXF) 15 days after dosing. Group 2 received only OXF. After the third dose of OXF, the goats were grazed together on the same pasture and fecal egg counts determined. No protection in immunized goats was achieved. In fact, immunized goats produced significantly more nematode eggs than the nonimmunized group.

The abbreviated injury scale as a predictor of outcome of severe head injury.

OBJECTIVE: This study examined the correlation between the worst abbreviated injury scale 1990 (AIS) intracranial severity score and outcome following severe head injury. DESIGN: The initial CT scans of 109 severely head injury patients were examined by a neuroradiologist and classified according to the worst applicable intracranial severity code from the AIS. This score was then correlated with the glasgow outcome scale (GOS) at 6 months. For comparison, the GOS was also correlated with the diffuse injury scale (DIS) described by L.F. Marshall et al. [5], the worst post-resuscitation Glasgow coma score (GCS) in the first 24 h, and the head injury outcome prediction tree described by Choi et al. [1]. RESULTS: Our results show Spearman rank correlation coefficients of 0.58 (p < 0.001), 0.47 (p < 0.001), 0.45 (p < 0.001), and 0.31 (p < 0.01) for the correlation between the AIS, prediction tree, DIS, and GCS respectively and the GOS. Independent outcome (i.e. GOS good or moderate) was strongly predicted by an AIS of 3 or less (positive predictive value 95%, specificity 98%, sensitivity 40%, likelihood ratio 25:1). Death or vegetative survival was less strongly predicted in patients with an AIS of 5 (positive predictive value 71%, specificity 75%, sensitivity 67%, likelihood ratio 2.7:1). CONCLUSION: The AIS, based on initial CT scan, provides useful prognostic information in patients with severe head injury.

[Magnetic resonance imaging. Sequence acronyms and other abbreviations in MR imaging].

The role of magnetic resonance imaging in clinical routine is still increasing. The large number of possible MR acquisition schemes reflects the variety of tissue-dependent parameters that may influence the contrast within the image. Those schemes can be categorized into gradient echo and spin echo techniques. Within these groups, further sorting can be done to differentiate between single-echo, multi-echo, and single-shot techniques. Each of these techniques can be combined with preparation schemes for modifying the longitudinal magnetization. Hybrids are found between the groups, which are those techniques that utilize spin echoes as well as gradient echoes. Academic groups as well as vendors often have different sequence acronyms for the same acquisition scheme. This contribution will sort these sequence acronyms into the previously mentioned scheme. The basic principle of the data acquisition is elaborated on and hints are given for potential clinical applications. Besides the sequence-specific acronyms, new abbreviations have surfaced recently in conjunction with parallel acquisition techniques." The latter means the utilization of multiple surface coils where the position and the sensitivity profile of the coils provide additional spatial information, allowing the application of reduced matrixes leading to a shorter measurement time.

Radiology considerations for the PREMIUM study: a multicenter randomized controlled trial of abbreviated MRI versus ultrasound for liver cancer screening in cirrhosis.

This paper describes the rationale and radiology considerations in the implementation of the Preventing Liver Cancer Mortality through Imaging with Ultrasound versus MRI (PREMIUM) study. PREMIUM is a multicenter, randomized controlled trial sponsored by the Department of Veterans Affairs comparing dynamic contrast-enhanced (DCE) abbreviated MRI (aMRI) plus serum AFP versus ultrasound (US) plus serum AFP for hepatocellular carcinoma (HCC) screening in patients with cirrhosis. PREMIUM aims to randomize 4,700 participants across over 47 Veterans Affairs Medical Centers to semiannual surveillance for up to eight years, with HCC-related mortality as the primary endpoint. To date, 35 sites have been activated with 1,085 patients randomized. To ensure uniform implementation and reporting of per-protocol screening, the PREMIUM Radiology Workgroup developed standardized imaging protocols, structured LI-RADS-based reporting templates, and a centralized training program for radiologists and technologists. They also perform ongoing quality control on both scans and reports. The aMRI protocols utilize multiphasic post-contrast imaging to allow LI-RADS scoring. A non-contrast-enhanced aMRI protocol is available for participants who develop renal impairment or contrast allergy during the study. US protocols conform to US LI-RADS standards. Structured reporting promotes consistency in documentation of findings, visualization scores, and follow-up recommendations. A centralized Image Repository was established, incorporating advanced de-identification methods to remove metadata and pixel-embedded protected health information from imaging files. More than 20,000 curated liver MRI and US exams are anticipated, supporting both trial outcomes and future radiomics and artificial intelligence research. PREMIUM aims to determine whether screening for HCC with a DCE aMRI protocol reduces HCC-related mortality and also facilitates ancillary studies utilizing the Image Repository.

Abbreviated injury scaling of head injury as a prognostic tool for functional outcome.

The use of Abbreviated Injury Scaling for the head region (HAIS) was evaluated as a prognostic index of functional outcome in 503 consecutive patients with severe injury to the brain who survived initial resuscitation. Although a strong statistical relationship between HAIS and outcome as measured by the Glasgow Outcome Scale was demonstrated, its clinical usefulness is limited. HAIS may be most useful as a classifier for comparative studies of populations and for the evaluation of therapeutic modalities.

Comparison of Turkish Injury Scale (TIS) with the Abbreviated Injury Scale (AIS).

According to the Turkish Penal Code, Section 456, an assailant is punished in a correlation to the severity of the victim's injury. In this study, the injury scale used in Turkey in the basis code 456 is compared with Abbreviated Injury Scale (AIS). For this aim, a total of 984 cases out of the total amount reported at the Traumatology Section of the Turkish Council for Forensic Medicine were randomly selected and evaluated retrospectively. In all, 40.7% of injuries were caused by blunt trauma, whereas 59.3% were caused by a penetrating trauma. According to the Turkish Injury Scale (TIS), 40.3% of the cases were scored to be of a first degree of injury, 15.6% as second degree and 44.1% as third degree. When compared, the score points 3, 4 and 5 in the AIS were seen to be nearly equivalent to the TIS of third degree. From this point of view, in the modified AIS 91.1% of first degree of injury, 51.2% of second degree and 97.2% of third degree of injury are harmonious with TIS. Generally, 83.2% of the cases are harmonious with the AIS system. The purpose of this study is to determine what was the source of differences and to focus on particular traumatic lesions in order to determine a possible rearrangement of the Turkish Injury Scale.

The Abbreviated Injury Scale. A valuable tool for forensic documentation of trauma.

Anatomic trauma scoring systems are fundamental to trauma research. The Abbreviated Injury Scale (AIS) and its derivative, the Injury Severity Score (ISS), are the most frequently used scales. We assessed the applicability of the AIS and the ISS systems for postmortem forensic documentation of trauma. In a prospective study, all trauma autopsies performed between January 1 and June 30, 1993, were coded according to the AIS and ISS method. All cases were reviewed by a consultant in forensic medicine and a traumatologist. Cases were grouped in three categories according to ISS values: 0-14, 16-66, and 75. These categories represent minor, major, and incompatible-with-life injuries, respectively. All autopsy findings in which ISS was < or = 14 were peer-reviewed to establish mechanism and cause of death. In the 6-month period, 279 trauma-related autopsies were studied. Age at death averaged 37.1 +/- 18.7 (mean +/- SD). Eighty-six percent of the victims were male. Penetrating trauma was the mechanism of injury in 67%. ISS was 0-14 in 19 cases, 16-66 in 150 cases, and 75 in 110 cases. In conclusion, AIS and ISS scoring systems are applicable to trauma forensic documentation. Using these methods for coding postmortem findings may help in establishing a database for trauma research, and this information could constitute a major part of continuous quality improvement of trauma management. Low ISS values may serve as a warning, sometimes indicating preventable death.

The Abbreviated Injury Scale: application to autopsy data.

Twenty autopsy reports, comprising 1 fall, 1 cutting, 1 burn, 1 drowning, 1 strangulation, 3 gunshot wound, and 13 traffic fatalities, were scored by the Abbreviated Injury Scale (AIS) and the Injury Severity Score (ISS). The codes were adequate for wounds of skin and long bones, and for most wounds of viscera. The autopsy descriptions were more detailed than the coding criteria for craniocerebral, cervicovertebral and muscular trauma, and less detailed for thoracoabdominal visceral, and long bone trauma. Lung contusions and rib fractures received scores that seemed unduly high, possibly reflecting the greater sensitivity of autopsy diagnosis over clinical diagnosis for these lesions. Complete hinge fractures of the skull base scored 4 (severe), which does not reflect the almost universally lethal nature of the accompanying cerebral concussion, which was itself not codeable. AIS scores were low and did not seem to reflect the lethal outcome when the lethal mechanism was purely physiologic and without a striking morphologic derangement, as in instances of cerebral or cardiac concussion, compression of the neck, occlusive airway hemorrhage, and visceral herniation into an adjacent body cavity. The scores were similarly low when therapy was delayed or adverse. Low AIS and ISS scores in a fatality from blunt or penetrating trauma may be useful retrospective clues to the presence of purely physiologic death mechanisms or therapeutic problems.

Abbreviated Injury Scale does not reflect the added morbidity of multiple lower extremity fractures.

OBJECTIVES: To determine if patients with multiple lower extremity fractures have worse outcomes than do patients with isolated femur fractures, and to determine if the Abbreviated Injury Scale (AIS) should distinguish between single and multiple lower extremity fractures. DESIGN: A retrospective study. MATERIALS AND METHODS: All blunt trauma patients at least 15 years of age treated at a level 1 trauma center from January 1990 through December 1993. Three groups of patients were selected. Group 1 included 50 patients whose only significant injury was a diaphyseal femur fracture. They had no other long bone fractures, minimal injuries to other body areas, and an Injury Severity Score (ISS) < or = 14. Group 2 was consisted of 29 patients with a femur fracture, at least one other diaphyseal lower extremity fracture, and also an ISS < or = 14. Group 3 consisted of 23 patients who had fracture patterns similar to those of group 2, but also had more severe nonextremity injuries (ISS > or = 15). Hospital morbidity and mortality rates were compared with t tests or chi-square analysis. Type 1 error probability was established at p < 0.05. MEASUREMENTS AND MAIN RESULTS: Compared with patients in group 1, patients in group 2 had an identical ISS (10.1 vs. 10.6, respectively), but had higher transfusion requirements (0.3 vs. 3.9 units), more days in the intensive care unit (ICU) (0.02 vs. 1.4), a higher incidence of adult respiratory distress syndrome (ARDS) (0 vs. 14%), longer hospital stays (6.0 vs. 14.8 days), greater disability at discharge (disability score 2.2 vs. 3.2), and a higher mortality rate (0 vs. 3.4%; p < 0.05 all variables). Patients in group 3 had worse outcomes than the other two groups: ISS = 30.1; transfusions = 11.9 units; ICU days = 9.1; ARDS incidence = 26%; hospital days = 29.9; disability score = 3.9; mortality = 26% (p < 0.05). CONCLUSIONS: Although AIS and ISS appropriately reflect the impact of extraskeletal injuries in patients with femur fractures, they do not adequately reflect the increased morbidity associated with multiple lower extremity fractures. The AIS-Extremity Score may need to be upgraded for multiple long bone fractures of the lower extremities.

Which of the abbreviated burn severity index variables are having impact on the hospital length of stay?

Quality control is an important tool ensuring continuous medical efficacy. Outcome scores, however, are unfavorable from a statistical point of view, are not meaningful for less severely injured patients, and may put the treating physicians under pressure to limit therapeutic efforts. In this study the variables of the abbreviated burn severity index (ABSI), primarily an outcome score, were used to predict length of hospital stay (HLS), a continuous quantitative variable reflecting treatment costs and incidence of complications even in less severely injured patients. For 365 patients a multiple linear regression analysis was used to evaluate the influence of the ABSI variables on HLS. Among survivors, age and total body surface area burned (TBSA) contributed significantly to HLS, whereas for nonsurvivors only TBSA significantly influenced HLS. Neither gender nor presence of full-thickness burn or inhalation injury showed a significant influence on HLS. The impact of age and TBSA on HLS might be used as a benchmarking system to evaluate quality of care. However, although HLS is probably widely dependent on regional health care systems, TBSA and age proved to be the only variables of the ABSI to correlate with HLS.

The Abbreviated Injury Scale and its correlation with preventable traumatic accidental deaths: a study from South Delhi.

Anatomic trauma scoring systems are fundamental to trauma research. The Abbreviated Injury Scale (AIS) and its derivative, the Injury Severity Score (ISS), are the most frequently used scales. In a prospective study, 400 autopsies of road traffic accident victims performed between January 2002 and December 2003 were coded according to the AIS and ISS methods. All the cases were classified into different injury groups according to the Injury Severity Scale. Fifty-eight cases (14.5%) were assigned an ISS value of <25; 244 (61%) cases were valued between 25-49; 38 cases (9.5%) were valued between 50-74 and 60 (15%) cases had a value of 75. On analysis of medical care, in cases with ISS<50, about 96% of the victims did not receive optimal care quickly enough with a lack of pre-hospital resuscitation measures and lengthy transportation time to hospital being of major importance.

[Objective evaluation of thoracic injuries and associated injuries using the Abbreviated Injury Scale and the New Injury Severity Score].

The authors focused attention on objectivization of the severity of chest injuries and associated injuries using the Abbreviated Injury Scale (AIS) and the New Injury Severity Score (NISS). They evaluated injuries detected on post-mortem examination in subjects who died from the sequelae of injuries in the Faculty Hospital Prague 10. The group comprised a total of 90 subjects regardless of sex aged 17-94 years who died in the hospital in 1996-2000. Traffic injuries accounted for 70% deaths, other blunt injuries for 27.8% and only 2.2% were penetrating injuries of the chest. The mean AIS value of the chest was 3.7, the mean value of NISS was 50.7. The NISS value declined in relation to age of the deceased patients and the period of survival. The period of survival varied from 30 mins. to 136 days. The mean NISS value on survival up to 5 hours after injury was 55.0. On comparison of our group we found that the results were consistent with those of American studies.

Comparisons of survival predictions using survival risk ratios based on International Classification of Diseases, Ninth Revision and Abbreviated Injury Scale trauma diagnosis codes.

BACKGROUND: We conducted a comparison of methods for predicting survival using survival risk ratios (SRRs), including new comparisons based on International Classification of Diseases, Ninth Revision (ICD-9) versus Abbreviated Injury Scale (AIS) six-digit codes. METHODS: From the Pennsylvania trauma center's registry, all direct trauma admissions were collected through June 22, 1999. Patients with no comorbid medical diagnoses and both ICD-9 and AIS injury codes were used for comparisons based on a single set of data. SRRs for ICD-9 and then for AIS diagnostic codes were each calculated two ways: from the survival rate of patients with each diagnosis and when each diagnosis was an isolated diagnosis. Probabilities of survival for the cohort were calculated using each set of SRRs by the multiplicative ICISS method and, where appropriate, the minimum SRR method. These prediction sets were then internally validated against actual survival by the Hosmer-Lemeshow goodness-of-fit statistic. RESULTS: The 41,364 patients had 1,224 different ICD-9 injury diagnoses in 32,261 combinations and 1,263 corresponding AIS injury diagnoses in 31,755 combinations, ranging from 1 to 27 injuries per patient. All conventional ICD-9-based combinations of SRRs and methods had better Hosmer-Lemeshow goodness-of-fit statistic fits than their AIS-based counterparts. The minimum SRR method produced better calibration than the multiplicative methods, presumably because it did not magnify inaccuracies in the SRRs that might occur with multiplication. CONCLUSION: Predictions of survival based on anatomic injury alone can be performed using ICD-9 codes, with no advantage from extra coding of AIS diagnoses. Predictions based on the single worst SRR were closer to actual outcomes than those based on multiplying SRRs.
