Primary amputation versus limb salvage in upper limb major trauma: a systematic review.

PURPOSE: Severe upper limb injuries can result in devastating consequences to functional and psychological well-being. Primary objectives of this review were to evaluate indications for amputation versus limb salvage in upper limb major trauma and whether any existing scoring systems can aid in decision-making. Secondary objectives were to assess the functional and psychological outcomes from amputation versus limb salvage. METHODS: A systematic review was carried out in accordance with PRISMA guidelines. A search strategy was conducted on the MEDLINE, EMBASE, and Cochrane databases. Quality was assessed using the ROBINS-I tool. The review protocol was registered in PROSPERO. RESULTS: A total of 15 studies met inclusion criteria, encompassing 6113 patients. 141 underwent primary amputation and 5972 limb salvage. General indications for amputation included at least two of the following: uncontrollable haemodynamic instability; extensive and concurrent soft tissue, bone, vascular and/or nerve injuries; prolonged limb ischaemia; and blunt arterial trauma or crush injury. The Mangled Extremity Severity Score alone does not accurately predict need for amputation, however, the Mangled Extremity Syndrome Index may be a more precise tool. Comparable patient-reported functional and psychological outcomes are seen between the two treatment modalities. CONCLUSIONS: Decision regarding amputation versus limb salvage of the upper limb is multifactorial. Current scoring systems are predominantly based on lower limb trauma, with lack of robust evidence to guide management of the upper extremity. Further high-quality studies are required to validate scoring systems which may aid in decision-making and provide further information on the outcomes from the two treatment options.

Non-operative management of non-destructive extra-peritoneal rectal injury.

This is a case report of extra-peritoneal rectal injury, secondary to a gunshot, that was managed non-operatively. A 57-year old male presented with a single gunshot to the right buttock and had blood per rectum. Extra-peritoneal rectal injuries were seen on proctoscopy and he had no genitourinary injury. He was managed successfully without rectal injury repair orfaecal stream diversion.

Development of an auditory test battery for young children: a pilot study.

This article describes the development and results of a pilot study with a recently developed auditory test battery for 4-6-year-old Dutch children. The test battery consisted of a sustained auditory attention (SAA) test, a dichotic words (DW) test, a binaural masking-level difference (BMLD) test, an auditory word discrimination (AWD) test, a gap detection (GD) test and a test of phonemic awareness, the Lindamood Auditory Conceptualization (LAC) test. Our results show that this test battery can be administered successfully to children aged 4 years and older. Most tests showed a clear effect of chronological age; the strongest age effects were found for the DW test and the LAC test. The BMLD test was the only test for which no significant age effect was found in this group of children. A small, but significant right-ear advantage was found on the DW test, for the 4- and the 6-year-olds. Correlations between subtests were in general rather high, suggesting that several tests in this test battery may be tapping into similar auditory abilities.

Development of auditory processing in 6-12-year-old children: a longitudinal study.

The development of auditory processing in children was investigated in a longitudinal study. A group of 20 children with normal cognitive and language development underwent several auditory tests at the ages of 6, 7, 8, 10 and 12 years. At the age of 10 years, three subjects were lost to follow-up, as was one more subject at the age of 12 years. The auditory performance of the children was compared to the performance of a group of 20 adults. The auditory test battery consisted of a speech-in-noise test, a filtered speech test, a binaural fusion test and two auditory sequencing tests. At the ages of 6, 7 and 8 years, data on the performance on an auditory word discrimination test, an auditory synthesis test, an auditory closure test and a number recall test were also obtained. All auditory tests except the speech-in-noise test showed a clear effect of age on the performance of children. Our data suggest that maturational effects play an important role in auditory processing (at least) up to an age of 12-13 years. Correlations between the tests are in general not indicative of large amounts of overlap between the different tests. Factor analysis shows that three factors account for 68-70% of explained variance, with the three factors contributing equally. A composite score obtained by averaging all (sub)test scores can be used next to the individual test scores to describe the development of auditory processing abilities in children.

Assessment of auditory processing in 6-year-old language-impaired children.

The performance of a group of twenty 6-year-old children with specific language impairment (SLI) on several behavioural auditory tests was compared to that of a group of twenty age-matched control children. The auditory test battery used in this study consisted of the following tests: a speech-in-noise test, a filtered speech test, a binaural fusion test, a frequency pattern test, a duration pattern test, a temporal integration test, an auditory word discrimination test, an auditory synthesis test, an auditory closure test and a number recall test. Our results show that the SLI children obtained scores on almost all tests that were significantly lower than those of the control group. Many of the basic auditory processing measures in our test battery correlated significantly with receptive and language scores, suggesting a (causal) relationship between auditory processing and language proficiency. Results from discriminant function analyses do not warrant deleting one or more tests from the test battery yet (with the exception of the auditory synthesis test and the temporal integration test, for which we did not find significant group effects). At present, we are conducting experiments with older (SLI and control) children and adults to find whether the significant performance deficits of the SLI children are also found in older SLI children, and to determine the influence of maturational effects on these auditory tests.
