Exploring the Attitudes of Pediatric Oncologists Toward the Use of Laxatives for the Prevention of Constipation in Patients Undergoing Active Treatment: A Canadian Perspective

Background: Constipation is a common problem in pediatric oncology patients and may lead to significant consequences. There is a paucity of the published literature on the prevention of constipation in this population. The primary purpose of this study was to explore the current practice of pediatric oncologists in preventing constipation in children receiving active chemotherapy treatment, specifically during periods of intensive vincristine therapy. Methods: A Web-based survey of pediatric oncologists and pediatric oncology trainees in Canadian centers was conducted. Results: A 48% response rate was achieved. The majority of physicians had a lower threshold for defining constipation in oncology patients compared with the published literature. More than 90% of the respondents estimated the prevalence of constipation in pediatric oncology patients to be 30% or higher. The majority of respondents prescribed constipation prophylaxis in the presence of one or more of the following factors: history of constipation prior to or during previous phases of therapy, vincristine combined with either narcotics or immobility, multiple vincristine doses per month, spinal cord compression and immobility, and isolated narcotic therapy. Polyethylene glycol 3350, lactulose, and ducosate were the most commonly recommended first-line prophylactic therapies used. Conclusion: Constipation is a significant problem in patients during cancer treatment. Most oncologists suggest giving laxatives as prophylaxis in the presence of risk factors, as well as prompt treatment once any symptoms appear. Our results suggest a role for the introduction of guidelines in the prevention of constipation, especially for patients receiving frequent vincristine therapy.     

Selective serotonin reuptake inhibitors in pregnancy and infant outcomes

Adequate treatment of depression during pregnancy is very important for maternal, fetal and neonatal health. Selective serotonin reuptake inhibitors (SSRIs) are commonly used antidepressants. According to one American study, approximately 7% of pregnant women were prescribed an SSRI in 2004–2005. First trimester use of SSRIs, as a group, is unlikely to increase the risk of congenital malformations. Paroxetine may be associated with a small increased risk of cardiac malformations, but evidence remains inconclusive. Fetal exposure to SSRIs closer to time of birth may result in respiratory, motor, central nervous system and gastrointestinal symptoms in about 10% to 30% of newborns (SSRI neonatal behaviour syndrome). These symptoms are usually mild and transient. Persistent pulmonary hypertension of the newborn is an extremely rare consequence of fetal exposure. This information should be used to make individual risk-benefit decisions when considering the treatment of depression during pregnancy. Newborns with late-pregnancy exposure to SSRIs should be observed in hospital for at least 48 h.     

Use of low-dose selective serotonin reuptake inhibitors for severe, refractory choking phobia in childhood

Difficulty swallowing solids and/or liquids accompanied by intense anxiety that results in restricted eating patterns or complete avoidance of eating may not have an easily identified underlying medical cause. This type of "eating disorder," which has also been described as "choking phobia," may occur in the absence of body image distortion, fear of becoming fat, or the desire to be thinner. The primary complaint in these children may be physical discomfort accompanied by high anxiety. Negative consequences can be severe and include social withdrawal, family distress, and deleterious effects on the child's physical health. Prompt recognition in the pediatric setting is, therefore, critical to avoid escalation of symptoms and treatment delays. Three pediatric cases of severe choking phobia refractory to prior intervention are presented in which rapid and sustained improvement followed low-dose therapy with a selective serotonin reuptake inhibitor (SSRI). Possible predictors of response to low-dose SSRI treatment in children with choking phobia and future avenues for investigation are explored.

Educational paper

Over the past several decades, pediatric oncologists have seen the growth in the number of patients surviving their cancer. This is in large part due to the use of multimodal therapy including chemotherapy, surgery, and radiotherapy. As the number of survivors of pediatric cancer continues to grow, however, we need to begin to focus on improving the quality of the lives that are being saved. Unfortunately, many regimens used today to cure pediatric cancer patients are gonadotoxic. Therefore, many of our survivors must contend with infertility. It is critical that pediatric oncologists consider the likelihood of gonadotoxicity prior to beginning therapy in this patient population in order to counsel patients and their families properly in order to potentially offer fertility preservation options. Conclusion: Infertility is a critical quality of life issue for pediatric cancer survivors and their families. Fertility preservation techniques need to continue to be studied and developed in order to lessen the likelihood that future cancer survivors will be infertile. This review outlines the risk for infertility, provides an assessment of the survivors reproductive functioning, and summarizes the currently available methods of preserving fertility in pediatric cancer survivors.     

Self-reported initial management of childhood idiopathic thrombocytopenic purpura: results of a survey of members of the American Society of Pediatric Hematology/Oncology, 2001

The purpose of this study was to update physicians' self-reported initial management practices for childhood idiopathic thrombocytopenic purpura (ITP) from an initial survey in 1997. A questionnaire was sent by e-mail in October 2001 to 753 members of the American Society of Pediatric Hematology/Oncology (ASPH/O). The questionnaire had 14 questions, based on the clinical presentation of a 5-year-old boy with ITP, a platelet count of 7,000/microL, scattered petechiae, and no mucous membrane bleeding. Two hundred eighteen (29%) surveys were returned. In response to questions regarding initial treatment, 33% of physicians said they would always administer drug therapy, 38% usually, 15% sometimes, and 14% rarely/never. When asked which agent would be used if drug treatment were prescribed, 45% reported anti-D, 33% IVIG, 20% prednisone, and 2% other regimens. Only 34% of physicians would always or usually hospitalize such a patient. Hospitalization was more likely if a physician responded that he or she would always or usually use drug therapy. Physicians who saw more ITP patients were more likely to self-report sometimes or rarely/never prescribing drug therapy. Self-reported initial management of ITP by ASPH/O members in 2001 is similar to 1997 regarding the percentage of pediatric hematologists who would not use drug therapy. Among physicians who would use drug treatment, there was an increased use of anti-D and decreased use of IVIG and prednisone. This information provides the basis for designing a randomized clinical trial to compare the effect of different management strategies on the outcomes of bleeding symptoms, side effects of therapy, costs, and quality of life.     

Ruling out the need for antibiotics: are we sending the right message?

OBJECTIVES: To examine the relationships among physician-parent communication practices, physicians' perceptions of parental expectations for antibiotic treatment, and inappropriate antibiotic prescribing for viral upper respiratory tract infections. DESIGN: Cross-sectional study of pediatric encounters motivated by cold symptoms between October 1, 2000, and June 30, 2001. Each encounter was videotaped. Physicians completed a postvisit survey that measured whether they perceived the parent as expecting antibiotics. Coded communication variables were merged with survey variables. Multivariate analyses identified key predictors of parent-physician communication practices, physician perceptions of parents' expectations for antibiotics, and inappropriate antibiotic prescribing for viral conditions. SETTING: Twenty-seven pediatric practices in Los Angeles, Calif. PARTICIPANTS: Thirty-eight pediatricians and 522 consecutively approached parents of children with cold symptoms. MAIN OUTCOME MEASURES: Physicians' perceptions of parental expectations for antibiotics, inappropriate antibiotic prescribing, and parental questioning of nonantibiotic treatments. RESULTS: Physicians were 20.2% more likely to perceive parents as expecting antibiotics when they questioned the physician's treatment plan (P = .004; 95% confidence interval, 6.3%-34.0%). When physicians perceived parents as expecting antibiotics, they were 31.7% more likely to inappropriately prescribe them (P<.001; 95% confidence interval, 16.0%-47.3%). Parents were 24.0% more likely to question the treatment plan when the physician ruled out the need for antibiotics (P = .004; 95% confidence interval, 7.7%-40.3%). CONCLUSIONS: Parental questioning of the treatment plan increases physicians' perceptions that antibiotics are expected and thus increases inappropriate antibiotic prescribing. Treatment plans that focus on what can be done to make a child feel better, rather than on what is not needed, ie, antibiotics, may decrease inappropriate antibiotic prescribing.     

Treatment practices in Tourette syndrome: the European perspective

AimsNational differences in licensing laws suggest that the use of medications for the treatment of Tourette syndrome differs between European countries. However, variability in prescribing practices has never been investigated. This study aims to systematically examine European prescribing practices in Tourette syndrome.MethodsAll members of the European Society for the Study of Tourette syndrome actively prescribing for paediatric and/or adult Tourette syndrome populations were invited to complete an online questionnaire covering pharmacological treatment of the five main symptom domains of Tourette syndrome: tics, attention-deficit hyperactivity symptoms, obsessive-compulsive symptoms, anxiety and depression.ResultsResponse rates were good, with 44/57 (77%) members returning the questionnaire. Risperidone (n = 13), methylphenidate (n = 21) and sertraline (n = 17) were the most commonly prescribed medications for the treatment of tics, attention-deficit hyperactivity symptoms and obsessive-compulsive symptoms, respectively. However, there was a large variability in both the medication choices and the dosages used for each of these symptom domains.ConclusionsThis is the first large-scale survey on prescribing habits for the pharmacological management of Tourette syndrome in Europe. In general, dopamine blockers were widely used for tics, selective serotonin reuptake inhibitors for depression, obsessive-compulsive symptoms and anxiety, and stimulants for attention-deficit hyperactivity symptoms, but there was high variation within these choices. Future studies need to target specific patient groups.     

An examination of the beliefs, attitudes and counselling practices of paediatric oncologists toward physical activity: A provincial survey

BACKGROUND

With an increasing population of childhood cancer survivors and a growing recognition of the long-term effects of diagnosis and treatment, it is imperative that modifiable risk factors for long-term health and disease comorbidity be identified and addressed. Physical activity is one therapy that is gaining credibility in enhancing quality of life and reducing the burden of disease.

OBJECTIVES

To examine the beliefs, attitudes and counselling practices of a group of Alberta-based paediatric oncologists.

METHODS

All Alberta-based physicians with a known specialty in paediatric oncology were approached and asked to complete a onetime, mail-out survey.

RESULTS

All responding physicians regarded both personal exercise and physical activity for childhood cancer survivors as moderately to extremely important. Importantly, one-half of the respondents believed that there is no adverse risk associated with physical activity in this survivor group. While the bulk of physicians report prescribing physical activity, few believe that their patients actually follow these recommendations.

CONCLUSIONS

Responding oncologists acknowledge the importance of physical activity for all survivors; however, future research is needed to better understand how to best promote healthy active living within this group.     

Endocrine complications of neoplastic diseases in children and adolescents.

Because of the increasing population of childhood cancer survivors, there is a need to focus on the late effects of cancer therapy. After discharge by their pediatric oncologists, it is essential that patients are not lost to the health system but rather are under continued surveillance with access to the appropriate physicians. Endocrine and metabolic consequences may impact the life of the patient both soon after cancer treatment and for many years in the future. The purpose of this article is to explore the current literature in the following areas: growth hormone (GH) deficiency, gonadotropin-releasing hormone (GnRH) analogues with GH therapy in childhood, safety of GH replacement, cardiovascular risk factors, osteopenia, thyroid problems, and gonadal damage resulting in infertility.     

Situación actual de los adolescentes con cáncer en las unidades de hemato-oncología pediátrica españolas

Little attention was paid to adolescents with Cancer in Spain up to 2010. In 2011 an “Adolescents with Cancer Committee” was established by the Spanish Society of Pediatric Hemato-Oncology (SEHOP) to care for the needs of these patients. The aim of this national survey was to outline the present situation of adolescents with cancer in Spanish Pediatric Hemato-Oncology units.A web based survey assessed institutional management of adolescents with cancer. The survey was personally sent to one member of the staff of each Pediatric Hemato-Oncology unit in Spain. It included questions about epidemiology, management, psycho-social coverage, specific facilities, and follow up of these patients.A total of 40 institutions out of 41 responded to the survey (overall response rate 98%). Fifty-six percent of the institutions had patients over 14, but only 36% of the institutions treated patients up to 18 years old. Only 25.6% of the units have more than 40 new pediatric cases every year. The percentage of patients between 14 and 18 years of age is below 10% in most of the units (77%).In 30.8% and 48.7% of the institutions, pediatric hemato-oncologists treat adolescents with hematological and solid tumors, respectively. The rest of the patients are seen by adult oncologists. There is only one institution that has a physician specifically dedicated to adolescent patients, and only two units have a “teenager's room”. Only 2 units have a psychologist specifically trained to treat adolescents with cancer.The survey shows that most adolescents with cancer in Spain between 14 and 18 years of age are treated by adult oncologists. Most pediatric institutions still do not have specific facilities and psychosocial support for adolescents. The SEHOP is working hard in order to improve the quality of cancer care, and the quality of survival of this population.     

Medical students' attitudes towards cancer: influence of the type of clerkship experience

Attitudes of third-year medical students relative to patients with cancer were assessed prior to and following three different 6-week pediatric clerkships. Clerkship I (N = 139) was conducted in a public hospital where student contact with all patients occurred in wards, supervised by pediatricians in all subspecialties. Clerkship II (N = 146) was in a pediatric hospital which is a cancer center. Contact with patients with cancer was directed by oncologists and nononcologists. Clerkship III (N = 31) was similar to II, with an exposure to an oncology ward. A 51-item instrument, employing a visual analog scale, which included general, adult, and pediatric items, was used (pre- & postclerkship) to evaluate attitudes in all 316 students and 49 faculty instructors associated with the clerkships. Factor analysis of student responses to pediatric items resulted in four factors: a) early diagnosis, b) aggressive therapy, c) long-range surveillance, and d) psychosocial support in reference to patients with cancer. Post-test differences between clerkship groups in items a and b were noted, with increasing positivity correlated with increased exposure to oncology and oncologists. Attitudes of faculty nononcologists differed significantly from those of oncologists irrespective of institutional affiliation.     

The role of abdominal x-rays in the diagnosis and management of intussusception.

The management of intussusception requires early diagnosis and reduction with either barium enema or surgical intervention. Supine and erect abdominal radiographs are often obtained prior to ordering a barium enema. In many pediatric centers, the critical, initial interpretation of these radiographs is made by nonradiologists and, in most instances, by pediatric emergency physicians. We determined the sensitivity and specificity of abdominal radiographs in diagnosing intussusception when interpreted by these physicians. Six full-time pediatric emergency physicians evaluated 126 radiographs from 42 patients with intussusception, 42 in whom the disease was clinically suspected but ruled out, and 42 in whom the final radiology report was "normal." These were presented to pediatric emergency physicians in a blinded, randomized sequence without any additional clinical information. These physicians then identified patients for whom they would proceed to barium enema. The mean sensitivity was 80.5% (range, 71-93%), and the mean specificity was 58% (range, 48-69%). This compares favorably to the sensitivity of signs and symptoms, and we conclude that plain and upright abdominal films are a useful adjunct for the clinician evaluating patients for suspected intussusception.     

“Per protocol” practice patterns for Children's Oncology Group trials within the radiation oncology community

Little is known about the prevalence of pediatric radiation oncologists treating patients off study according to Children's Oncology Group (COG) trials before data are available regarding toxicity and efficacy of novel radiotherapy regimens. We conducted a 12-question survey of 358 pediatric radiation oncologists to characterize practice patterns regarding ongoing and completed COG protocols off study. With 130 responses (40.3%), the prevalence of providing treatment per protocol, but off study, before data are available in abstract or peer-reviewed form varied from 9.1% (for ACNS1422) to 88.1% (for AHOD1331). Future studies are needed to understand the effects of these practice patterns on outcomes.
