Longitudinal vocabulary development in Australian urban Aboriginal children: Protective and risk factors.

BACKGROUND: Vocabulary is a key component of language that can impact on children's future literacy and communication. The gap between Australian Aboriginal and non-Aboriginal children's reading and academic outcomes is well reported and similar to Indigenous/non-Indigenous gaps in other nations. Determining factors that influence vocabulary acquisition over time and may be responsive to treatment is important for improving Aboriginal children's communication and academic outcomes. AIM: To determine what factors influence Australian urban Aboriginal children's receptive vocabulary acquisition and whether any of these are risks or protective for vocabulary development. METHOD: One hundred thirteen Aboriginal children in South Western Sydney from the longitudinal birth cohort Gudaga study were assessed on The Peabody Picture Vocabulary Test multiple times: 3 years, just prior to school entry, at the end of the first and second years of formal schooling. Multilevel models were used to determine the effects of 13 fixed and manipulable maternal, child, and family variables drawn from previous research. RESULTS: Higher maternal education was found to be protective at 3 years and over time. The number of children in urban Australian Aboriginal households made an impact on vocabulary development and this varied over time. From 3 to 6 years, those with early poor non-verbal cognitive skills had vocabulary skills that remained below those with stronger non-verbal skills at 3 years. Girls exhibit an earlier advantage in vocabulary acquisition, but this difference is not sustained after 4 years of age. CONCLUSIONS: The risk and protective factors for vocabulary development in Australian Aboriginal children are similar to those identified in other studies with some variation related to the number of children in the home. In this limited set of predictors, maternal education, gender, non-verbal cognitive skills, and the number of children in households were all shown to impact on the acquisition of vocabulary to 3 years and or the developmental trajectory over time.

The tin whistle: a rare and serious cause of penetrating oropharyngeal trauma in children.

Impalement injuries of the oral cavity are common in children and the potential for serious complications including internal carotid artery thrombosis can be unnoticed. We present a patient who sustained a penetrating injury in which a "tin whistle" caused herniation of the parotid gland which was not detected on clinical examination. We discuss the challenging clinical examination, the role of investigations, and consequences of these injuries aiming at increasing awareness and optimizing patient management.

Who gets help for pre-school communication problems? Data from a prospective community study.

OBJECTIVE: Pre-school communication problems are common, with implications for school readiness and educational achievement. Help is available from a variety of community healthcare providers. This study examined the extent to which help is received, and the predictors of service receipt. DESIGN AND SETTING: Prospective community study, in Melbourne, Victoria. PARTICIPANTS AND METHOD: At age 4 years, we assessed the speech, receptive and expressive language and fluency of 1607 children and gave feedback to their parents. At age 5 years, 983 families provided data on service use for communication problems between and 4 and 5 years. We compared service use between participants with and without impairment, and used logistic regression to estimate the strength of association between potential predictors (gender, socio-economic status, maternal education, English-speaking background status, family history of speech and language problems and parent concern) and service use (binary outcome). RESULTS: Data were available for both communication status and service use for 753 children. Only 44.9% of the 196 children with communication impairment received help from a professional. Furthermore, 7% of the 557 that did not meet criteria for communication impairment nevertheless received help from a professional. Parent concern was the strongest predictor of service use (adjusted odds ratio = 9.0; 95% CI: 5.6-14.8). CONCLUSIONS: Both over- and under-servicing for communication problems were evident. This study shows that accessing help for communication problems requires more than simply informing parents about the problem and having services available; there is a need for systematic support to get the right children to services.

Long term functional results from major limb replantations.

Replantation is now firmly established as a viable treatment option in traumatic limb amputation, yet there are few long-term studies describing the functional outcome of these cases. The purpose of the present study was to evaluate long-term results in a population of such patients to determine overall success and patient satisfaction. Since 1981, twenty macro-replants involving nineteen patients have been performed in our unit. All patients were reviewed by means of case note analysis, patient questionnaire, and follow-up clinical evaluation for functional outcome using the Tamai scoring system. Acute limb salvage was successful in 18/20 (90%) cases. One patient is still undergoing secondary reconstructive surgery and was unable to be assessed for final outcome leaving 17 replanted limbs that underwent full functional assessment. Overall functional results were good in 7/17 (41%) limbs, fair in 7/17 (41%) and poor in 3/17 (18%). The majority of patients (12/17) claimed to be highly or well satisfied with their outcome and eleven have returned to work since their injury. The current study of major limb replantation demonstrates favorable or acceptable long term functional outcomes in the majority of cases. High patient satisfaction rates even where results were poor emphasise the positive psychological impact of successful replantation.

The untold truth about "bath salt" highs: A case series demonstrating local tissue injury.

The epidemic of injecting cathinone derivatives, marketed as "bath salts", by intravenous drug users among inner city Dubliners led to an associated rise in soft tissue complications. The spectrum of the cases encountered, ranging from self-limiting cellulitis to extensive abscess formation, at a single institution is described.

Self-inflicted burns in the Irish National Burns Unit.

We carried out a review of self-inflicted burns presenting to the National Burns Unit in the Republic of Ireland. 87 self-inflicted burns were identified over a 12-year period accounting for 4.2% of total Burns Unit admissions. Patient demographics were identified. The majority of patients had a history of mental illness and deliberate self harm. We also examined the motivation behind the self-immolation, the total body surface area involved and the mortality rates.

Tuberculous dactylitis in the setting of low serum vitamin D: a case report.

We present the case of a previously well patient who presented to the Emergency Department of a Dublin hospital with a tuberculous infection of his dominant index finger and a very low serum vitamin D level--this has been implicated in both primary and reactivation infections with Mycobacterium Tuberculosis. This case highlights and reviews both the importance of considering non-endemic pathologies in the setting of a patient base of diverse ethnicity, and the emerging importance of vitamin D in the immune response to M. tuberculosis infection. We discuss the relevant literature to highlight the background of this disease process, and the importance of a multidisciplinary approach to these patients.

Predictors of parents seeking help or advice about children's communication development in the early years.

BACKGROUND: Children's access to services for communication disorders is often determined by parental decisions to seek help or advice. The factors that predict whether parents seek help/advice about their child's communication development were explored in this study. METHODS: Parents of children in a large, community cohort of children (the Early Language in Victoria Study) were asked whether they had sought help or advice about speech and language development at 1, 2, 3 and 4 years. Child, family and environmental variables, as well as parental concern and children's communication status, were used to predict help/advice seeking. The communication abilities of those in the help-seeking group were also evaluated. RESULTS: Gender, age, children's communication status and parental concern were consistent predictors of help/advice seeking. Significant over and under-identification was evident, and there was preliminary evidence that children with overt communication difficulties (such as unintelligible speech) were more likely to receive help. CONCLUSIONS: Parental support and education, as well as education of professionals who regularly have contact with young children, is necessary to support appropriate early identification of communication problems. Further research into service level factors such as availability and accessibility which may support or inhibit help/advice seeking is also indicated.

Free tissue transfer versus pedicled flap reconstruction of head and neck malignancy defects.

BACKGROUND: With the advent of microsurgery the pedicled flap is considered by many to be an outdated surgical option. AIMS: To explore the relationship between flap survival and pre-morbid risk factors, conduct a comparative analysis of flap and systemic morbidities and complete a cosmesis and functionality assessment for oral and oropharyngeal reconstruction patients. METHODS: 114 patients, over a 13-year period, who had a one-stage reconstructive procedure employing the pectoralis major myocutaneous flap (PMMF) or radial forearm-free flap (RFFF). RESULTS: Variables, including age, smoking and radiation exposure were not statistically significant predictors of flap survival probability. Atelectasis was a significant post-op finding of RFFF patients. Flap dehiscence of >50% was a significant morbidity of PMMF. No statistical difference in cosmetic deformity, diet and socialisation was noted. CONCLUSIONS: Pectoralis major myocutaneous flap remains an enduring and safe flap; however, the RFFF has markedly improved speech performance over the PMMF.

Unnecessary inter-hospital referral of minor hand injuries: a continuing problem.

BACKGROUND: Trauma patients are a burden on resources in terms of personnel, operating time and bed occupancy. The plastic surgery trauma clinic was established in January 1999 and has been running Monday to Friday mornings from 9 am to 1 pm since its establishment. AIM: To analyse and compare referral patterns to the Plastic Surgery trauma clinic over three time periods. METHOD: Three time groups were analysed and compared: data from this initial study (2000-2001), a retrospective chart review (2002-2003), as well as a prospective study (2006-2007). RESULTS: Numbers of attendances at the Trauma Clinic seem to be increasing every year despite encouragement by letter after the initial study for local centres to treat many of the minor injuries not requiring plastic surgical skills. CONCLUSION: Admission rates have remained below 50% of the patients seen in the clinic; however 50% of patients required only local anaesthetic procedures performed in the clinic, or no treatment at all (27.6% of patients in 2003, 35.3% in 2006).

Parental consent for neuroimaging in paediatric research.

BACKGROUND: Functional magnetic resonance imaging (fMRI) is increasingly applied in paediatric research. Parents typically provide research consent for their children; yet, no study has examined the rates of consent, nor factors influencing parental decision making for consent. The present study aimed to determine the proportion of parents that would consent to their child undergoing an fMRI study, and to elicit the reasons, motivators and detractors affecting their decision. METHODS: Ninety parents of children aged 6 years were invited to participate in a postal survey study. RESULTS: Fifty-three parents (59%) responded and one-third (34%, 18/53) reported that they would consent. The main reason for consent was that participation could benefit children in the future (89%, 16/18). Common reasons for not consenting included that fMRI may be anxiety-provoking (54%), or was an unnecessary medical procedure (23%). CONCLUSIONS: Our preliminary data suggest that researchers may have to approach three times the number of participants required in order to recruit a suitable number of healthy children to fMRI studies. Further research examining the influence of recruitment approaches (e.g. phone vs. postal) and the various factors influencing decision making regarding consent is required. For example, careful examination of the language used in describing the procedure could facilitate parental understanding about fMRI and alleviate anxiety associated with the procedure. This is an important consideration for recruitment to future fMRI studies given that anxiety was a key factor influencing parental non-consent.

Burning more than calories: treadmill friction injuries in children.

Treadmill injuries in young children are a serious but little documented problem. Friction burns occur when the hands come into contact with the moving belt resulting in deep burns that often require hospital admission and surgery. The aim of this study was to assess the nature and prevalence of injuries sustained and to highlight treadmill friction burns as a public health issue previously undocumented in Ireland. A retrospective chart review from January 2006 until March 2008 was performed and functional outcome was assessed by the modified Michigan Hand Outcomes Questionnaire. Eight girls and four boys from one year and seven months to seven years and five months were treated. Eight children required admission to hospital and to date three have required surgery for their injuries. This is a new and increasing problem in Ireland which must be highlighted.

The Early Language in Victoria Study: predicting vocabulary at age one and two years from gesture and object use.

The Macarthur-Bates Communicative Development Inventories (CDI) have been used widely to document early communicative development. The paper reports on a large community sample of 1,447 children recruited from low, middle and high socioeconomic (SES) areas across metropolitan Melbourne, Australia. Regression analyses were conducted to determine the extent to which communicative behaviours reported at 0 ; 8 and 1 ; 0 predicted vocabulary development at 1 ; 0 and 2 ; 0. In support of previous findings with smaller, often less representative samples, gesture and object use at 1 ; 0 were better predictors of 2 ; 0 vocabulary than were gesture and object use at 0 ; 8. At 1 ; 0, children from the lower SES groups were reported to understand more words than children from the higher SES groups, but there were no SES differences for words produced at 1 ; 0 or 2 ; 0. The findings add to our understanding of the variability in the development of early communicative behaviours.

Backyard burning.

This study was undertaken to determine whether changes had occurred in the numbers of burns that could be related to backyard burning subsequent to the introduction of the council tax throughout Eire for the collection of household refuse. Numbers of patients admitted to our unit who had sustained burns by burning rubbish were recorded prospectively over a period of 12 months. A random control group was taken as three years prior to this and results found by retrospective chart review. Between January and November 2005, 168 patients were admitted to the National Burns Unit, St James's Hospital Dublin, Ireland. Nineteen of these patients sustained flame burns from backyard burning. One hundred and seventy patients were admitted in the comparative period of 2002; Seven of these from backyard burning. The total number of inpatient days for these patients in 2005 (255) was significantly more than in 2002 (68) (p=0.024). The numbers in our study show a marked increase in the number of patients sustaining burns in this manner, and appear to correlate with the introduction of bin charges by a number of county councils around the country last year. This study demonstrates that the introduction of legislation can have an unforeseen adverse affect on the population if not introduced in correlation with appropriate public education. While the introduction of waste charges represents a very necessary move forward in waste disposal in Ireland, public awareness campaigns should be implemented to prevent further such injuries from occurring.

Analysis of functional results and quality of life following free jejunal flaps for reconstruction after upper aerodigestive neoplastic resection: the St James's experience.

Surgical treatment of hypopharyngeal cancers with extension to the postcricoid region generally requires a circumferential pharyngolaryngoesphagectomy followed by reconstruction of the upper aerodigestive tract. Many techniques have been described in order to achieve a safe and functional reconstruction. Interposition of the jejunal free flap (JFF) is a well-established technique and is the flap of choice in our unit. This is a retrospective review of all patients who required a JFF following pharyngolaryngoesphagectomy over an 9-year period. We studied medical charts, histological reports, and speech and language therapy assessments. Eight of the nine surviving patients completed a quality of life questionnaire. Analysis was carried out on patient demographics, flap survival, patient survival and quality of life including swallow function and speech restoration. A total of 23 patients had 24 jejunal free flaps. There were four perioperative deaths. Two flaps failed, and were salvaged with a second JFF in one case and a gastric pull-up in the second. Functioning swallow was established in 74% of patients with four patients complaining of dysphagia. Speech was restored using an electrolarynx or Blom Singer valve in 70% of patients. Most patients required radiotherapy as part of their adjuvant treatment. In our hands the JFF for reconstruction following pharyngolaryngoesophageal resection allows restoration of function following major ablative surgery.

Firework injuries presenting to a national burn's unit.

The sale to the general public of fireworks is illegal in Ireland. However, many fireworks are readily available on the black market from illegal traders. The number of firework injuries presenting to our unit during the three week run-up to Hallowe'en October 2001 was recorded. In addition, each patient was contacted to determine how the fireworks were obtained, the average amount of money spent, and the level of adult supervision present at the time of injury. A total of 19 patients presented, 18 from the local catchment area, with a mean age of 16 yrs (range 5-46 yrs). Thirteen patients required admission. Sixteen patients sustained hand injuries including burns, and three sustained burns to other body areas. The amount of money spent varied between adults and children, the average amount among the paediatric group was Euro 2-4, but Euro 45 in the adult group. None were willing to identify the local source of their fireworks, but most fireworks originated in Northern Ireland. This small review highlights an ongoing problem in Ireland; fireworks are illegal, yet they are easily and cheaply available without quality or safety controls. Our public awareness campaign has failed to reach its target audience, and the illegal traders who sell these often inferior products are seldom charged. Children and adults will continue to sustain serious injuries as a result.
