Use of mobile telephone short message service as a reminder: the effect on patient attendance

Background: Nonattendance for hospital outpatient appointments is a major burden on healthcare systems and the estimated financial loss can be high. Various reasons for patients not attending have been reported, including the patient/carer forgetting the appointment and confusion over the date and time of the appointment. Various reminder systems have been trialled across a variety of clinical settings. More recently, short message service (SMS) text messaging has emerged as a viable approach for delivering reminders to outpatients at a relatively low cost. Aims and objectives: To evaluate the effect of appointment reminders, sent as SMS text messages to patients’ mobile telephones, on attendance at outpatient clinics at the ITS Centre for Dental Studies and Research (ITS‐CDSR), Muradnagar, Ghaziabad, Uttar Pradesh, India. Materials and methods: The study was conducted at ITS‐CDSR in the Departments of Prosthodontics, Endodontics, Orthodontics and Paedodontics. Patients attending these departments for a period of 4 months and those who had provided a contact mobile number were sent an SMS reminder. Results: In this study, 206 subjects (male, 124; female, 82) participated, 96 (male, 57; female, 39) of whom were in the test group and 110 (male, 67; female, 43) of whom were in the control group. The rate of attendance on time was found to be significantly higher in the test group (79.2%) than in the control group (35.5%). Conclusion: The study results indicate that sending appointment reminders as text messages to patients is an effective strategy to reduce nonattendance rates.     

When nouns and verbs degrade: Facilitating communication in semantic dementia

Background: Little is known about how to maintain communicative effectiveness in semantic dementia as the disease progresses from impairment in word retrieval to a loss of conceptual knowledge.

Aim: The purpose of this study is twofold. The first objective is to characterise communicative effectiveness using a modified framework derived from Chapman and Ulatowska (1997 Chapman, S. B. and Ulatowska, H. K. 1997. “Discourse in dementia: Consideration of consciousness.”. In Language structure, discourse and the access to consciousness, Edited by: Stamenov, M. I. 155–188. Philadelphia: John Benjamin Publishing Company.  [Google Scholar]) that integrates two components: codification of ideas (falling on a continuum from verbal to nonverbal and generative to automatic forms) and functions of communication (imaginative, heuristic, informative, personal, interactional, regulatory, and instrumental). The second objective is to outline principles of a discourse intervention that focuses on communicative effectiveness.

Method & Procedures: The participant was Mr Bobby V, a man with semantic dementia. His communication abilities were characterised at diagnosis and 24 months later using the framework of communicative effectiveness, based on discourse samples, clinical observation, and caregiver report. From the time of diagnosis, Bobby V received discourse intervention, which focused on maintaining his communication abilities using all available communication resources. We outline principles of discourse intervention in semantic dementia based on our experience of delivering individual and group intervention to Bobby V.

Outcomes and Results: The communicative effectiveness framework described here could be used to characterise communication skills, set therapy goals, and monitor progress in semantic dementia. Discourse intervention likely facilitated Bobby V's continued success in maintaining communication despite progressive loss of nouns and verbs.

Conclusions: Targeting conversational effectiveness in terms of communicative functions offers a promising and ecologically valuable intervention for people with semantic dementia, as it allows individuals with this form of dementia to connect meaningfully with people in their immediate surroundings well into the later stages of the disease.     

Hyperexcitability of inferior colliculus neurons caused by acute noise exposure

Noise exposure is one of the most common causes of hearing loss. Recent studies found that noise exposure‐induced cochlear damage may change the excitability and tonotopic organization of the central auditory system (CAS). This plasticity was suspected to be related to tinnitus and hyperacusis. However, how cochlear damage affects CAS function and causes these neurologic diseases is still not clear. CAS function is activity dependent, so we hypothesize that a restricted cochlear lesion might disrupt the balance of excitation and inhibition in the CAS and thereby affect its neural activity. To test this hypothesis, we studied the effects of narrow‐band noise exposure on the firing properties of neurons in the inferior colliculus (IC), which has complex neural circuits and plays an important role in sound processing. We found that noise exposure (20 kHz, 105 dB SPL, 30 min) caused a dramatic decrease of the characteristic frequency in about two‐thirds of high‐frequency neurons with/without causing a significant threshold shift. The noise exposure also caused an increase in firing rate of the low‐frequency neurons at suprathreshold levels, whereas it dramatically decreased the firing rate of the high‐frequency neurons. Our results suggest that acute high‐frequency noise exposure may increase low‐frequency responsiveness by causing hyperexcitability of low‐frequency neurons. The functional change of the low‐frequency neurons may be related to the disruption of side‐band inhibition at the noise exposure frequencies caused by cochlear damage. © 2012 Wiley Periodicals, Inc.     

Motor and cognitive assessment of infants and young boys with Duchenne Muscular Dystrophy: results from the Muscular Dystrophy Association DMD Clinical Research Network

Therapeutic trials in Duchenne Muscular Dystrophy (DMD) exclude young boys because traditional outcome measures rely on cooperation. The Bayley III Scales of Infant and Toddler Development (Bayley III) have been validated in developing children and those with developmental disorders but have not been studied in DMD. Expanded Hammersmith Functional Motor Scale (HFMSE) and North Star Ambulatory Assessment (NSAA) may also be useful in this young DMD population. Clinical evaluators from the MDA-DMD Clinical Research Network were trained in these assessment tools. Infants and boys with DMD (n = 24; 1.9 ± 0.7 years) were assessed. The mean Bayley III motor composite score was low (82.8 ± 8; p ? .0001) (normal = 100 ± 15). Mean gross motor and fine motor function scaled scores were low (both p ? .0001). The mean cognitive comprehensive (p = .0002), receptive language (p ? .0001), and expressive language (p = .0001) were also low compared to normal children. Age was negatively associated with Bayley III gross motor (r = ?0.44; p = .02) but not with fine motor, cognitive, or language scores. HFMSE (n = 23) showed a mean score of 31 ± 13. NSAA (n = 18 boys; 2.2 ± 0.4 years) showed a mean score of 12 ± 5. Outcome assessments of young boys with DMD are feasible and in this multicenter study were best demonstrated using the Bayley III.     

Clinico – diagnostic and therapeutic relevance of computed tomography scan of brain in children with partial seizures

Background:

Therapeutic relevance of computed tomography (CT) in children with partial seizures is reported to be remarkably low (1-2%). However, in the developing countries where infections involving the nervous system are common, routine CT scan of brain may help in finding treatable causes of seizures.

Objective:

Aim of this study was to evaluate the significance of CT scan of brain in the management of children with partial seizures.

Materials and Methods:

Children with partial epilepsy, whose predominant seizure type was focal motor seizures, were included in the study. CT scan of brain was done in all children aged between 1 month and 12 years with partial seizures of unknown etiology prospectively. The clinical findings of these children were noted along with the CT findings.

Results:

Between August 2001 and July 2002, of the 200 children with seizure disorder 50 children who satisfied the inclusion criteria were included in the study. CT scan of brain was normal in 16 children (32%) and was abnormal in 34 children (68%). Twenty children (~60% of abnormal scan) had potentially correctable lesions: Tuberculoma (n = 13), neurocysticercosis (n = 3), and brain abscess (n = 4). Five children had changes representing static pathology that did not influence patient management. The clinical features correlated with CT findings in 78% children.

Conclusion:

Children with partial motor seizures have high probability of having abnormal findings on CT scan of brain, especially, neuro-infections which are potentially treatable. Therefore, CT scan brain should be carried out in all children with partial motor seizures especially, in developing countries.     

Transitional services for adolescents with epilepsy in the UK: A survey

PurposeTo survey the current transitional epilepsy services in tertiary paediatric neurology centres in the UK within the principles of transitional care for young people with epilepsy.MethodsAn online web-based questionnaire was sent to the lead epilepsy clinicians in tertiary paediatric neurology centres on behalf of the British Paediatric Epilepsy Group, the specialist epilepsy group of the British Paediatric Neurology Association (BPNA). A transition clinic was defined as a ‘clinic or service that provided joint paediatric and adult supervision of care from paediatric to adult services’.ResultsTwenty-three centres were approached of which18 responded and 15 of which provided auditable data. The clinics were held between three and 12 times per year, mostly in the afternoon and sited equally between the paediatric and adult centre. Approximately three to five new, and three to eight follow up patients were seen in each clinic. Most clinics accepted new referrals with a minimum age of 14 and a maximum of 20 years. Most young people were seen only once in a transition clinic before then being promoted into the adult epilepsy service. Very few clinics accepted direct referrals from the GP. Adult, slightly more than the paediatric team provided out-of-hospital advice after the young person was seen in the transition clinic.ConclusionsYoung people with epilepsy are a challenging, but interesting group and their care at this time may have a potentially irreversible impact on their life. Their progress from paediatric to adult services should be a dynamic, gradual and smoothly transitioned process to optimise their care. Although recommended by the National Institute for Health and Clinical Excellence (NICE) and the National Services Framework (NSF), the findings of this survey would suggest an un-met need of this population.     

Acute complications of movement disorders surgery: Effects of age and comorbidities

The most common indication for movement disorder surgery is Parkinson's disease (PD), and the incidence of PD increases with age. The analysis reported here was undertaken with the primary goal of examining whether there is a relationship between peri‐operative complications and age. The Nationwide Inpatient Sample (Agency for Healthcare Research and Quality, Rockville, MD, USA) was queried for 10 years beginning in 1999 for patients undergoing deep brain stimulator insertion, pallidotomy, and thalamotomy for treatment of PD, essential tremor, and dystonia. Inpatient complications, including death, stroke (both ischemic and hemorrhagic), and other overall complications were examined. The relative risks associated with advanced age; primary diagnosis; treatment modality; the diagnoses of hypertension, diabetes, and nicotinism; and the cumulative number of comorbidities were examined. There were 5464 patients who met inclusion criteria, including 4145 patients treated for PD and 4961 patients treated with deep brain stimulation (DBS). Overall in‐hospital mortality was 0.26%, with 0.15% related to surgical factors. There was a correlation between in‐hospital mortality, increasing age, and number of medical comorbidities. After multivariate regression no factor remained predictive of mortality. Having more than 1 medical comorbidity or PD increased the risk of in‐hospital complications. Patients with PD were more likely to suffer hemorrhage or stroke. Hypertension, diabetes, nicotinism, and modality of treatment were not associated with increased mortality, hemorrhage or stroke risk, or in‐hospital mortality in univariate or multivariate analysis. Both age and medical comorbidity are correlated with in‐hospital complications, but age appears to serve as a surrogate for comorbidity. Surgery for PD appears to carry an increased risk of hemorrhage or stroke and in‐hospital complications. © 2013 International Parkinson and Movement Disorder Society     

Cardiac output monitoring to guide fluid replacement in head and neck microvascular free flap surgery-what is current practice in the UK?

Appropriate fluid balance is an important factor in the survival of free flaps, and recently there has been a shift towards more conservative fluid regimens. Several surgical specialties have made extensive use of the relatively non-invasive method of measuring cardiac output (CO) to optimise fluid balance during and after surgery, which has resulted in a shorter hospital stay, but little has been published in head and neck surgery. To ascertain its use in the head and neck we sent a postal questionnaire to the anaesthetic departments of 40 major head and neck units identified from the 2010 database of the British Association of Oral and Maxillofacial Surgeons (BAOMS). Questions were asked about the number of free flaps done in the unit each year, the monitoring of central venous and arterial blood pressure (and inotrope protocols), optimal target variables, and whether CO was monitored (with type of device). Thirty-two units responded (80%). While 26 units (81%) routinely monitored central venous pressure (CVP), CO was monitored in only 3 units (9%). There was a wide range of responses in relation to optimal variables and use of inotropes. As with other specialties, it is likely that CO monitoring will become widely used in head and neck reconstructive surgery. Not only does it enhance fluid optimisation, but it may also reduce hospital stay and morbidity. Appropriate clinical studies are urgently needed to evaluate its use in our specialty.
