Use and need for post-acute services following paediatric head injury

This paper aims to document the types of inpatient and outpatient post-acute services children receive after discharge from an acute care hospital for head injury and to better understand the extent to which children fail to receive services and the reasons for not receiving needed services. A follow-up was conducted on 95 children (aged 5-15) 1 year after they were hospitalized for head injury. Parents were interviewed by phone concerning their child's use of and need for medical, rehabilitation, and social services since the injury. Questions were also asked regarding the child's current health status and behaviour. Inpatient records were reviewed to obtain information on the characteristics of the injury. Overall use of outpatient rehabilitation and social services was low during the year following injury, ranging from 0-18% of the study sample. Although need for and use of services was positively correlated with head injury severity, it appears that unmet need was highest for children with the least severe head injuries. Finally, need for physical or occupational therapy and mental health services was unrecognized for one third of children with physical limitations and 40% of children with at least 14 identified behaviour problems. These findings underscore the need for physicians and other health care professionals to thoroughly evaluate children during follow-up visits as well as during the initial hospitalization for head injury-related deficits. Identification of functional deficits or behavioural problems should be followed-up by evaluation and treatment by qualified rehabilitation professionals.     

Formal retrospective case review and sudden infant death

A review of 24 consecutive sudden infant deaths was undertaken to evaluate the importance of the various stages in the postmortem assessment of such cases. Death in three cases was caused by obvious trauma. Of the remainder, 16 were attributed to sudden infant death syndrome (SIDS), 4 to accidental asphyxia (identified by death scene examination and/or formal case review) and 1 to a lingual thyroglossal duct cyst. Three (14%) of 21 deaths thought to be SIDS after postmortem examination were attributed to asphyxia following subsequent formal case review.     

Recombinant human relaxin as a cervical ripening agent

Objective The aim of this study was to investigate the efficacy and safety of recombinant human relaxin (rhRIx) as a cervical ripening agent in women with an unfavourable cervix before induction of labour at term.
Design A multi-centre, double-blind, placebo-controlled trial performed in Edinburgh, Glasgow and Oxford. Women were treated with 0, 1, 2 or 4 mg of rhRIx in a gel vehicle administered intravaginally. Analysis of variance tests were performed on all continuous variables, and Cochran Mantel-Haenszel tests employed for all discrete variables.
Participants Ninety-six women at 37 to 42 weeks of gestation with a singleton pregnancy and a modified Bishop score of 4 were recruited.
Results There was no significant difference in the change in modified Bishop score between the four treatment groups. The lengths of the first and second stages of labour were similar in all 4 groups. PGE₂ and oxytocin requirements were similar in all groups, as was the mode of delivery. There was no evidence that relaxin was absorbed systemically when given in this way.
Conclusion Recombinant human relaxin 1 to 4 mg, administered as an intravaginal gel, has no effect as a cervical ripening agent before induction of labour at term.     

Chordoma: Radiological–pathological correlation

This review correlates the imaging findings and histological appearances seen in chordomas in a series of patients presenting at our institution, together with a published literature review. A parallel presentation of photographs of imaging findings and microscopic histological findings is made, with the aim being to enhance recognition of this uncommon but clinically significant entity.     

Determinants of disability after lower extremity fracture

BACKGROUND: Factors influencing the progression of physical impairment to patient-perceived disability are not well known. We sought to better understand this relationship in the setting of injury. METHODS: We followed a cohort of 302 patients with lower extremity fractures over a 1-year period. Physical impairment was assessed by range of motion, strength, and pain. Range of motion and strength were assessed together as a proportion of normal function of the extremity (impairment score). Pain was assessed using a Visual Analogue Scale (VAS) pain score. Disability was assessed using the Sickness Impact Profile (SIP), a widely used measure of patient-perceived limitations of everyday activities attributable to illness. The SIP was administered during hospitalization to assess preinjury baseline. Impairment assessment and readministration of the SIP were performed at 12 months after injury. RESULTS: Impairment in leg function (range of motion and strength) was highly correlated (p < 0.001) with overall SIP score at 12 months, but accounted for only 23% of the variance in overall SIP scores. Likewise, VAS pain score was highly correlated (p < 0.001) with overall SIP score at 12 months, but accounted for only 29% of the variance in overall SIP scores. In a multivariate linear regression analysis, variables that were independently associated with overall SIP score included impairment score, VAS pain score, preinjury SIP, poverty status, education status, social support, having hired a lawyer, and involvement with workers' compensation. These variables accounted for 52% of the variance in overall SIP scores at 12 months. CONCLUSION: The degree of physical impairment accounts for only a small amount of the variance in disability from lower extremity fracture. Identifiable patient characteristics including age, socioeconomic status, preinjury health, and social support together with impairment account for over half of the variance in long-term disability. Further research is needed to increase understanding of other factors that influence the progression of impairment to disability, especially those factors that may be amenable to intervention.     

Allen Cognitive Level Screen for the classification of subjects treated for addiction

Introduction The Cognitive Disabilities Model (CDM) is an occupational approach that can allow the classification of the functional-cognitive abilities of persons with addictions. The objective of the study was to explore the applicability of the ACLS-5 to assess a sample of persons undergoing addiction-rehabilitation treatment. Methods A sample of 232 participants was recruited from an outpatient treatment centre in Madrid (Spain). The ACLS-5, the Montreal Cognitive Assessment (MoCA), and the Prefrontal Symptom Inventory (PSI) were administered. Sociodemographic and addiction-related data were also obtained. Results Half of the sample showed serious deficits in functional cognition, which ultimately could be related to problems in their daily performance. Scores of ACLS-5 showed significant correlations with the severity of addiction, with those obtained with the MoCA, and with attentional symptoms on the PSI scale. Conclusions The data suggest the applicability of the ACLS-5 in assessing the degree of functional cognition in subjects treated for addiction, providing evidence to support ecological validity and facilitating the development of well-targeted cognitive rehabilitation programmes from an occupational perspective. The use of occupational-based instruments to assess the functioning of those with addictions is a requirement of occupational therapy professionals working in this general area.     

Three-generation reproduction study of rats ingesting up to 10% sorbitol in the diet--and a brief review of the toxicological status of sorbitol

Groups of 12 male and 24 female 5-wk-old Charles River CD (SD) BR rats (F0) were fed a sucrose-containing ground cereal-based diet in which 0, 2.5, 5.0 and 10.0% (w/w) sorbitol was included at the expense of sucrose. The rats were first mated after 14 wk on the diet. F1a litters were born 19 wk after the start of the study and F1b litters at wk 30. Groups of 12 male and 24 female F1b rats were first mated when 18 wk old. They gave rise to F2a litters after 3 wk and to F2b litters 10 wk later. Likewise, groups of 12 male and 24 female F2b rats were first mated when 18 wk old, producing F3a and F3b litters 3 wk and 10 wk later, respectively. F0 rats were killed 33 wk after the start of the study, F1a in wk 22, F1b in wk 68, F2a in wk 57, F2b in wk 92 and F3a in wk 96. Apart from slight reductions in food consumption in sorbitol-fed F1b males and in body-weight gain in sorbitol-fed F0, F1b and F2b rats of both sexes, treatment was associated with no clinically observed effects. There were no deaths attributable to treatment and no adverse effects on mating performance or pregnancy rates in the parent animals of any generation. Treatment was associated with no consistent adverse effect on any measure of reproductive performance or behaviour during gestation or lactation. No abnormal pups were observed in any generation. Not unexpectedly, caecal enlargement was consistently observed at necropsy of sorbitol-treated rats of all generations and significant rises in serum calcium were observed in F0 males and females exposed to 10% sorbitol and in F1b males exposed to either 5 or 10% sorbitol. Differences between treated and control F3a rats in respect of T3 and TSH levels were probably spurious as they followed no consistent pattern. Similarly, between-group variations in gonadal weight were considered to have no toxicological significance because they lacked consistency and were not accompanied by any histologically-evident changes. Microscopic examination of lesions from F1a and F2a animals, of gonads from F1b and F2b and of selected tissues from the F3a generation revealed no changes of toxicological significance.(ABSTRACT TRUNCATED AT 400 WORDS)
