Digital health tools for pain monitoring in pediatric oncology: a scoping review and qualitative assessment of barriers and facilitators of implementation.

PURPOSE: We aimed to systematically identify and characterize existing digital health tools for pain monitoring in children with cancer, and to assess common barriers and facilitators of implementation. METHODS: A comprehensive literature search (PubMed, Cochrane, Embase, and PsycINFO) was carried out to identify published research on mobile apps and wearable devices focusing on acute and/or chronic pain in children (0-18 years) with cancer (all diagnoses) during active treatment. Tools had to at least include a monitoring feature for one or more pain characteristic(s) (e.g., presence, severity, perceived cause interference with daily life). Project leaders of identified tools were invited for an interview on barriers and facilitators. RESULTS: Of 121 potential publications, 33 met inclusion criteria, describing 14 tools. Two methods of delivery were used: apps (n=13), and a wearable wristband (n=1). Most publications focused on feasibility and acceptability. Results of interviews with project leaders (100% response rate), reveal that most barriers to implementation were identified in the organizational context (47% of barriers), with financial resources and insufficient time available mentioned most often. Most factors that facilitated implementation related to end users (56% of facilitators), with end-user cooperation and end-user satisfaction mentioned most often. CONCLUSIONS: Existing digital tools for pain in children with cancer were mostly apps directed at pain severity monitoring and little is still known about their effectiveness. Paying attention to common barriers and facilitators, especially taking into account realistic funding expectations and involving end users during early stages of new projects, might prevent evidence based interventions from ending up unused.

Dutch norms for the Strengths and Difficulties Questionnaire (SDQ) - parent form for children aged 2-18 years.

BACKGROUND: Identification of children at risk for psychosocial problems is important to be able to provide supportive and tailored care at an early stage. Due to its brevity and wide age range, the Strengths and Difficulties Questionnaire (SDQ) Parent Form is an appropriate instrument for use in paediatric clinical practice as it facilitates assessment of psychosocial functioning from young childhood into adulthood. The aim of the present study was to provide Dutch normative data for the SDQ Parent Form. METHODS: A sample of 1947 parents with children aged 2-18 years was drawn from a large panel of a Dutch research agency, stratified on Dutch key demographics of the parents. The SDQ Parent Form assesses the child's Emotional symptoms, Conduct problems, Hyperactivity-Inattention, Peer problems and Prosocial behaviour. Summary scores can be calculated: Internalising, Externalising and Total difficulties. Internal consistency (Cronbach's alpha coefficient) and normative scores (mean, median, clinical cut-off scores) of the SDQ- Parent Form were calculated in four age-groups 2-3, 4-5, 6-11 and 12-18 years. Gender differences were tested with independent t-tests. RESULTS: A total of 1174 parents (60.3%) completed the SDQ. In the age-groups 2-3 and 4-5, norm scores are not available for Conduct problems and Peer problems due to insufficient internal consistency. In addition, in age-group 2-3, norm scores for Emotional symptoms and Internalising are not available because of insufficient internal consistency. In the age-groups 6-11 and 12-18, norm scores are available for all scales, with Cronbach's alpha coefficients 0.53-0.86. The comparison by gender revealed that boys had more behavioural problems than girls (0.000 < p < 0.048), most prevalent for Hyperactivity-Inattention, Peer Problems, Prosocial behaviour, Externalising and Total Difficulties. CONCLUSIONS: Dutch normative data by age-group and gender are now available for parent-reported SDQ scores in children aged 2-18 years. Due to insufficient internal consistency, normative scores for 2-5 year-old children could not be presented for several SDQ scales. Yet, the SDQ Total score provides a reliable indication of the psychosocial functioning of younger children. In case of high Total scores in children younger than 6 years, alternatively to scale scores, the answers on the individual items could yield useful clinical information about the child's problems.

Match of psychosocial risk and psychosocial care in families of a child with cancer.

OBJECTIVE: The Psychosocial Assessment Tool (PAT) was developed to screen for psychosocial risk, aimed to be supportive in directing psychosocial care to families of a child with cancer. This study aimed to determine (i) the match between PAT risk score and provided psychosocial care with healthcare professionals blind to outcome of PAT assessment, and (ii) the match between PAT risk score and team risk estimation. METHODS: Eighty-three families of children with cancer from four pediatric oncology centers in the Netherlands participated (59% response rate). The PAT and team risk estimation was assessed at diagnosis (M = 40.2 days, SD = 14.1 days), and the content of provided psychosocial care in the 5-month period thereafter resulting in basic or specialized care. RESULTS: According to the PAT, 65% of families were defined as having low (universal), 30% medium (targeted), and 5% high (clinical) risk for developing psychosocial problems. Thirty percent of patients from universal group got basic psychosocial care, 63% got specialized care, and 7% did not get any care. Fourteen percent of the families at risk got basic care, 86% got specialized care. Team risk estimations and PAT risk scores matched with 58% of the families. CONCLUSIONS: This study showed that families at risk, based on standardized risk assessment with the PAT, received more specialized care than families without risk. However, still 14% of the families with high risks only received basic care, and 63% of the families with standard risk got specialized care. Standardized risk assessment can be used as part of comprehensive care delivery, complementing the team.

Health related quality of life in Dutch infants, toddlers, and young children.

BACKGROUND: The purpose of this study is to provide Dutch normative data and to assess internal consistency and known-groups validity for the TNO AZL Preschool Children Quality of Life (TAPQOL) and the acute version of the generic Pediatric Quality of Life Inventory (PedsQL 4.0) in Dutch young children aged 0-7 years. METHODS: Participants were selected from a panel of a large Dutch market research agency. A sample of 794 parents (response rate 61%, 39% fathers) of children (53% boys) from the general Dutch population, completed an electronic version of the TAPQOL (N = 227 infants aged 0-1 years) or PedsQL 4.0 (N = 293 toddlers aged 2-4 years and N = 274 young children aged 5-7 years). RESULTS: Except for the 'stomach' scale (α = .39), the TAPQOL showed acceptable to excellent internal consistency (α = .60-.88). The PedsQL 4.0 showed acceptable to excellent reliability in children aged 2-4 years (α = .60-.88) and in children aged 5-7 years (α = .76-.90). Children with a chronic health condition had lower scores than healthy children on 3 out of 12 domains of the TAPQOL (p = .001-.013) and on 2 out of 6 domains of the PedsQL 4.0 for children aged 2-4 years (p = .016-.04). The PedsQL 4.0 differentiated on all domains (p < .05) between children aged 5-7 years with and without a chronic health condition. CONCLUSION: In Dutch children aged 0-7 years old, HRQoL can be relialy measured with the TAPQOL and the PedsQL 4.0. However, it remains unclear whether these HRQoL instruments can distinguish between healthy children and children with a chronic health condition under the age of 5.

Facial trauma.

Facial trauma. Patients with facial trauma must be assessed in a systematic way so as to avoid missing any injury. Severe and disfiguring facial injuries can be distracting. However, clinicians must first focus on the basics of trauma care, following the Advanced Trauma Life Support (ATLS) system of care. Maxillofacial trauma occurs in a significant number of severely injured patients. Life- and sight-threatening injuries must be excluded during the primary and secondary surveys. Special attention must be paid to sight-threatening injuries in stabilized patients through early referral to an appropriate specialist or the early initiation of emergency care treatment. The gold standard for the radiographic evaluation of facial injuries is computed tomography (CT) imaging. Nasal fractures are the most frequent isolated facial fractures. Isolated nasal fractures are principally diagnosed through history and clinical examination. Closed reduction is the most frequently performed treatment for isolated nasal fractures, with a fractured nasal septum as a predictor of failure. Ear, nose and throat surgeons, maxillofacial surgeons and ophthalmologists must all develop an adequate treatment plan for patients with complex maxillofacial trauma.

Secondary non-Hodgkin lymphoma of the ethmoid sinus after temozolomide.

The paranasal sinuses are rarely the site of malignancy, especially non-Hodgkin lymphoma. In such cases, the ethmoid sinus is the second most frequently involved paranasal sinus. Diagnosis of these malignancies is difficult because the early symptoms often mimic benign sinus pathology. Thus, most cases are diagnosed at an advanced stage, and their prognosis is poor. Here we describe the case of a 58-year-old man with a secondary high-grade B-cell non-Hodgkin lymphoma of the ethmoid sinus. This malignancy was diagnosed two years after the patient had received treatment with temozolomide for a glioblastoma multiforme. This case highlights that malignant tumours of the paranasal sinuses should always be included in the differential diagnosis of sinus disease. Additionally, patients treated with temozolomide should receive regular follow-up care including vigilant evaluation for secondary tumours, such as non-Hodgkin lymphoma.

Angiosarcoma arising in an arteriovenous fistula in a patient without kidney transplant.

Angiosarcomas are relatively rare and account for only 1% of all sarcomas. They arise from endothelial cells of blood or lymph vessels. They are usually highly aggressive and long term outcome is poor with an overall 5-year survival rate of 10-20%. We report the case of a 80-year old man with an angiosarcoma arising in a non-functioning arteriovenous fistula. Angiosarcomas arising in an arteriovenous fistula are very rare and only eleven cases were found in the literature. In nine cases (82%) chronic immunosuppression, taken for renal transplant, was one of the causing factors. Our patient however did not receive a kidney transplant and was not on immunosuppressive therapy. Clinicians should be aware that an angiosarcoma can arise in an arteriovenous fistula even without chronic immunosuppression.

Patient reported outcomes in pediatric oncology practice: suggestions for future usage by parents and pediatric oncologists.

Several studies in adults have shown patient reported outcomes (PROs) to be effective in enhancing patient-physician communication and discussion of Health Related Quality of Life outcomes. Although less studied, positive results have been demonstrated in children. A PRO-intervention needs to be feasible in clinical practice to be successful. In the current study, 74 parents of children who successfully completed their cancer treatment and 21 pediatric oncologists (POs) evaluated a PRO-intervention and gave recommendations for future use in their practice. Most parents and POs suggested PROs to be an important part of standard care, starting during treatment, with an assessment frequency of every 3 months.

Iptakalim attenuates self-administration and acquired goal-tracking behavior controlled by nicotine.

Iptakalim is an ATP-sensitive potassium channel opener, as well as an α4ß2-containing nicotinic acetylcholine receptor (nAChR) antagonist. Pretreatment with iptakalim diminishes nicotine-induced dopamine (DA) and glutamate release in the nucleus accumbens. This neuropharmacological profile suggests that iptakalim may be useful for treatment of nicotine dependence. Thus, we examined the effects of iptakalim in two preclinical models. First, the impact of iptakalim on the interoceptive stimulus effect of nicotine was evaluated by training rats in a discriminated goal-tracking task that included intermixed nicotine (0.4 mg/kg, SC) and saline sessions. Sucrose was intermittently presented in a response-independent manner only on nicotine sessions. On intervening test days, rats were pretreated with iptakalim (10, 30, 60 mg/kg, IP). Results revealed that iptakalim attenuated nicotine-evoked responding controlled by the nicotine stimulus in a dose-dependent manner. In a separate study, the impact of iptakalim on the reinforcing effects of nicotine was investigated by training rats to lever-press to self-administer nicotine (0.01 mg/kg/infusion) [Dosage error corrected]. Results revealed that pretreatment with iptakalim (1, 3, 6 mg/kg, IV) decreased nicotine intake (i.e., less active lever responding). Neither behavioral effect was due to a non-specific motor effect of iptakalim, nor to an ability of iptakalim to inhibit DA transporter (DAT) or serotonin transporter (SERT) function. Together, these finding support the notion that iptakalim may be an effective pharmacotherapy for increasing smoking cessation and a better understanding of its action could contribute to medication development.

Predicted versus executed surgical orthognathic treatment.

OBJECTIVES: This study aimed to analyse combined surgical-orthodontic treatment plans, compare them with the actual surgery performed, and define factors resulting in changes of the original plan during orthodontic pre-surgical preparation. STUDY DESIGN: The clinical files of 312 orthognathic surgery patients, operated between January 2008 and December 2010, were retrospectively reviewed. Of these 312 patients, 129 had a bimaxillary operation. One hundred sixty patients had osteotomy of the lower jaw only and 23 had osteotomy of the upper jaw only. Factors analysed in the study include Angle Class malocclusion, patient sex, and age. Lip-to-incisor relationship, overjet, overbite and midline deviations of the upper and lower jaw were recorded. Effects of surgical assisted rapid palatal expansion (SARPE) on the eventual surgery were also investigated. Reasons for changing the original treatment plan at the time of the finished pre-surgical-orthodontic alignment were analysed. RESULTS: The original treatment plan was changed in 42 of the 312 patients (13.5%). Changes occurred generally in case of a larger interval between set-up of the first treatment plan and the eventual operation (average 22.4 versus 16.4 months for patients with changed versus unchanged treatment plan, respectively). All Class I patients had surgery performed as planned. Class III patients had a significantly higher rate of altered treatment plan (27.3%) than Class II patients (7.6%). More men (52.4%) saw their treatment plan changed, although there were more women than men in the study population (59.6 versus 40.4%). CONCLUSION: One in seven patients (13.5%) had a different operation than was planned at the start of treatment. Class III patients with small overjet and overbite commonly have a treatment plan for a monomaxillary operation that, after decompensation, needs to be adapted to a bimaxillary operation.

CBCT-based predictability of attachment of the neurovascular bundle to the proximal segment of the mandible during sagittal split osteotomy.

Injury to the inferior alveolar nerve (IAN) during surgery is an important complication of bilateral sagittal split osteotomy. With cone beam computed tomography, the course of the nerve and its relationship to the surrounding structures can be assessed in three dimensions. This study aims to determine whether tomography can predict attachment of the neurovascular bundle to the proximal segment of the mandible during sagittal split osteotomy (SSO). Bilateral linear measurements were taken on cross-sectional tomography images. During osteotomy, it was noted for each patient whether the neurovascular bundle was attached to the proximal segment during the split. If attached, a bone-cutting instrument or a blunt instrument was needed to free the nerve. The nerve was attached at more than one-third of operation sites (170 sites). Of these, over 65% of attached nerves (108 sites) required a bone-cutting intervention to free them from the mandible. After correcting for confounding factors, the linear distances from the buccal cortical margin of the IAN canal to the inner and outer buccal cortical margins of the mandible were important predictors of whether the IAN will be attached to the proximal segment of the mandible during SSO.

Lateral cephalometry changes after SARPE.

Surgically assisted rapid palatal expansion (SARPE) is associated with postoperative cephalometric changes. In this study we analyse these changes in the sagittal plane in orthognathic patients undergoing SARPE followed by orthodontic treatment and Le Fort I, bilateral sagittal split osteotomy (BSSO), or bimaxillary surgery. This is a retrospective review of 50 patients (20 males, 30 females) undergoing orthognathic treatment with SARPE to correct transversal deficiency of the maxilla as part of a comprehensive treatment plan. PP-SN, SNA, and ANB angles were increased and U1-SN and U1-PP angles were decreased. All changes were statistically significant. Changes of SNB, PP-Mand plane angle, and SN-Mand. plane angle were not statistically significant. Surgically assisted rapid palatal expansion using a bone-borne appliance as a preparative step for later orthognathic surgery results in clockwise rotation of the maxilla.

Long-term success and survival rates of autogenously transplanted canines.

OBJECTIVES: The objectives of this study were to determine the long-term survival and success rates of autotransplanted canines and to investigate the influence of various parameters on the long-term success rate. STUDY DESIGN: Fifty-nine patients (73 transplanted canines) volunteered to participate in this study. The mean follow-up time was 11 years. Different parameters that could influence the outcome of transplantation were examined in the patient files. Each transplanted canine was clinically and radiologically evaluated. Logistic regression analyses were performed. RESULTS: The survival rate was 75.3%, because 18 transplanted teeth were lost before examination. The success rate for all transplanted teeth was 57.5%, because 42 transplanted teeth were evaluated as clinically successful. The most significant parameter in determining the success rate of autotransplantation was age at transplantation (P = .0429). CONCLUSION: Autotransplantation of impacted canines may have a successful outcome 11 years after transplantation. The success rate increases when performing the transplantation at a younger age.

Development of a clinically applicable tool for bone density assessment.

OBJECTIVES: To assess the accuracy and reliability of new software for radiodensitometric evaluations. METHODS: A densitometric tool developed by MevisLab was used in conjunction with intraoral radiographs of the premolar region in both in vivo and laboratory settings. An aluminum step wedge was utilized for comparison of grey values. After computer-aided segmentation, the interproximal bone between the premolars was assessed in order to determine the mean grey value intensity of this region and convert it to a thickness in aluminum. Evaluation of the tool was determined using bone mineral density (BMD) values derived from decalcified human bone specimens as a reference standard. In vivo BMD data was collected from 35 patients as determined with dual X-ray absorptiometry (DXA). The intra and interobserver reliability of this method was assessed by Bland and Altman Plots to determine the precision of this tool. RESULTS: In the laboratory study, the threshold value for detection of bone loss was 6.5%. The densitometric data (mm Al eq.) was highly correlated with the jaw bone BMD, as determined using dual X-ray absorptiometry (r = 0.96). For the in vivo study, the correlations between the mm Al equivalent of the average upper and lower jaw with the lumbar spine BMD, total hip BMD and femoral neck BMD were 0.489, 0.537 and 0.467, respectively (P < 0.05). For the intraobserver reliability, a Bland and Altman plot showed that the mean difference +/- 1.96 SD were within +/-0.15 mm Al eq. with the mean difference value small than 0.003 mm Al eq. For the interobserver reliability, the mean difference +/-1.96 SD were within +/-0.11 mm Al eq. with the mean difference of 0.008 mm Al eq. CONCLUSIONS: A densitometric software tool has been developed, that is reliable for bone density assessment. It now requires further investigation to evaluate its accuracy and clinical applicability in large scale studies.

Small bowel gastrointestinal stromaltumor (GIST) arising in a jejunal diverticulum.

In this report, we present a very rare case of a small bowel GIST arising in a true jejunal diverticulum in a 56-year-old woman.

The impact of mandibular advancement on articulation, resonance and voice characteristics in Flemish speaking adults: a pilot study.

Bilateral saggital split osteotomy (BSSO) of the mandible is a frequently performed mandibular orthognathic procedure, used to resolve mandibular disharmonies. Literature review showed contradictory findings regarding the effect of the orthognathic surgery on speech characteristics. The purpose of the present study was to determine a detailed analysis of the articulation, resonance and voice characteristics after BSSO with mandibular advancement for the treatment of Class II malocclusions using objective and subjective assessment techniques (perceptual evaluations, Dysphonia Severity Index, nasalance scores) in eight subjects. The findings of the present study indicate that before and after BSSO with mandibular advancement three types of articulation disorders may predominate in the Flemish language: the incorrect production of the trill sound /r/ and the /s/ sound and devoicing of the /z/. After orthognathic surgery most patients showed an identical articulation pattern (normal or disturbed pattern) as in the presurgical condition. In this study the BSSO with mandibular advancement had no significant impact on the nasality characteristics and the nasalance values probably due to the competent velopharyngeal valving in the presurgical condition. And, as expected the vocal quality revealed no significant difference. The maxillofacial surgeon and the speech language pathologist must be aware of the persistency of these preoperative articulation errors in the postsurgical condition.

Image-based planning and clinical validation of zygoma and pterygoid implant placement in patients with severe bone atrophy using customized drill guides. Preliminary results from a prospective clinical follow-up study.

The zygoma implant has been designed for those situations where there is insufficient bone in the upper jaw, which would otherwise require onlay or inlay (sinus) bonegrafts. The aim of the study was to present and validate a planning system for implant insertion based on preoperative CT imaging. It allows the surgeon to determine the desired position of different kinds of implants. Finally a customized drill guide is produced by stereolithography. In this study, zygoma, pterygoid and regular platform implants were used. The treatment protocol is validated through 12 case studies, selected at random from the total patient group (n=29 patients). From postoperative images, the exact implant location is determined and the deviation of axes between planned and inserted implants is calculated. In this in vivo study, displacements, varying according to the type of implant and the location of the implants, were observed. From a clinical standpoint, most of the inserted implants were judged to be adequately sited. A prospective clinical follow-up study was performed on all 29 patients. Although all patients presented with severe maxillary atrophy, excellent cumulative survival rates (92%) for the zygoma implants and 93% for regular platform implants have been obtained.
