Cognitive behavioural therapy with optional graded exercise therapy in patients with severe fatigue with myotonic dystrophy type 1:a multicentre, single-blind, randomised trial

Background: Myotonic dystrophy type 1 is the most common form of muscular dystrophy in adults and leads to severe fatigue, substantial physical functional impairment, and restricted social participation. In this study, we aimed to determine whether cognitive behavioural therapy optionally combined with graded exercise compared with standard care alone improved the health status of patients with myotonic dystrophy type 1. Methods: We did a multicentre, single-blind, randomised trial, at four neuromuscular referral centres with experience in treating patients with myotonic dystrophy type 1 located in Paris (France), Munich (Germany), Nijmegen (Netherlands), and Newcastle (UK). Eligible participants were patients aged 18 years and older with a confirmed genetic diagnosis of myotonic dystrophy type 1, who were severely fatigued (ie, a score of ≥35 on the checklist-individual strength, subscale fatigue). We randomly assigned participants (1:1) to either cognitive behavioural therapy plus standard care and optional graded exercise or standard care alone. Randomisation was done via a central web-based system, stratified by study site. Cognitive behavioural therapy focused on addressing reduced patient initiative, increasing physical activity, optimising social interaction, regulating sleep–wake patterns, coping with pain, and addressing beliefs about fatigue and myotonic dystrophy type 1. Cognitive behavioural therapy was delivered over a 10-month period in 10–14 sessions. A graded exercise module could be added to cognitive behavioural therapy in Nijmegen and Newcastle. The primary outcome was the 10-month change from baseline in scores on the DM1-Activ-c scale, a measure of capacity for activity and social participation (score range 0–100). Statistical analysis of the primary outcome included all participants for whom data were available, using mixed-effects linear regression models with baseline scores as a covariate. Safety data were presented as descriptives. This trial is registered with ClinicalTrials.gov, number NCT02118779. Findings: Between April 2, 2014, and May 29, 2015, we randomly assigned 255 patients to treatment: 128 to cognitive behavioural therapy plus standard care and 127 to standard care alone. 33 (26%) of 128 assigned to cognitive behavioural therapy also received the graded exercise module. Follow-up continued until Oct 17, 2016. The DM1-Activ-c score increased from a mean (SD) of 61·22 (17·35) points at baseline to 63·92 (17·41) at month 10 in the cognitive behavioural therapy group (adjusted mean difference 1·53, 95% CI −0·14 to 3·20), and decreased from 63·00 (17·35) to 60·79 (18·49) in the standard care group (−2·02, −4·02 to −0·01), with a mean difference between groups of 3·27 points (95% CI 0·93 to 5·62, p=0·007). 244 adverse events occurred in 65 (51%) patients in the cognitive behavioural therapy group and 155 in 63 (50%) patients in the standard care alone group, the most common of which were falls (155 events in 40 [31%] patients in the cognitive behavioural therapy group and 71 in 33 [26%] patients in the standard care alone group). 24 serious adverse events were recorded in 19 (15%) patients in the cognitive behavioural therapy group and 23 in 15 (12%) patients in the standard care alone group, the most common of which were gastrointestinal and cardiac. Interpretation: Cognitive behavioural therapy increased the capacity for activity and social participation in patients with myotonic dystrophy type 1 at 10 months. With no curative treatment and few symptomatic treatments, cognitive behavioural therapy could be considered for use in severely fatigued patients with myotonic dystrophy type 1.

The use of rotational fluoroscopy and 3-D reconstruction in the diagnosis and surgical planning for complex cloacal malformations

© 2019 Elsevier Inc. Introduction: Cloacal malformations, a confluence of the urinary tract, vagina and rectum into a single common channel, has a broad and complex anatomic spectrum requiring an imaging tool for visualization, measurement, and surgical planning for the reconstruction of these structures. We evaluated the role of 3-D fluoroscopy for this purpose, as it offers a combination of spatial correlation with precise anatomic measurements. Methods: We examined our imaging protocol for patients with a cloacal malformation and report our experience with rotational fluoroscopy and 3-D reconstruction in 16 consecutive patients referred for cloacal reconstruction. The length of the common channel (CC), the length of the urethra from the bladder neck to the common channel, and the height (and existence or absence) of a vagina or vaginas were determinants of the surgical procedures used for the repair. Results: We performed 16 consecutive 3-D cloacagrams (age range 4 months to 9 years) using a new protocol (Figure 1) that provided the following data which helped with surgical planning: Gynecologic: 3 cases with a single vagina, 5 cases with a duplicated Mullerian system (3 of which were asymmetric) and 2 cases with high vaginas requiring vaginal replacement. Colorectal: Four had a high rectum requiring an abdominal approach, and 6 had a rectum reachable via a posterior sagittal approach. Urologic: Two ectopic ureters requiring reimplantation, 3 patients had vesicoureteral reflux (1 bilateral, 2 unilateral), 1 patient had no bladder, and 7 had a normal sized bladder. Common channel length and urethral length were demonstrated in all cases and used to decide between a total urogenital mobilization or a separation of vagina(s) from the common channel, urogenital separation. Conclusion: The 3-D cloacagram can help predict the surgical plan for urologic, gynecologic, and colorectal components of the cloacal repair. It can predict the CC length as well as the length of the urethra. It helps with predicting the need for vaginal replacement and whether an abdominal approach is needed for the rectum. Its effectiveness is based on the ability to adequately distend structures and see their distal most extent, an advantage over other modalities such as MRI. Added benefits (particularly from the 3D view) include a better spatial understanding of the defect and the diagnosis of concomitant urological abnormalities such as vesicoureteral reflux and ectopic ureters. Disadvantages to this procedure include the need for general anesthesia and a higher exposure to radiation. Level of evidence: 3

Does clinic visit education within a multidisciplinary center improve health literacy scores in caregivers of children with complex colorectal conditions?

© 2017 Introduction Health literacy is low in an estimated one-third of the US population. Little is known about the health literacy of caregivers of children with colorectal conditions. The objective of this study was to investigate whether a timed health literacy intervention could improve health literacy in this population. Methods We used the BRIEF Health Literacy screening (BHLS) tool on caregivers of children who came to our colorectal clinic. Health literacy was categorized as inadequate, marginal, or adequate. The number of caregivers with adequate health literacy was compared to the number of clinic visits and socioeconomic status. Results We included 233 caregivers. The average number of clinic visits was 3.5 over 1.2 years. At the first clinic visit, 70% (n = 98) of caregivers had “adequate” health literacy. Scores improved to 88% (p = 0.024) after the fourth visit. Socioeconomic factors were not associated with health literacy. Patients of caregivers with “adequate” health literacy visited our clinic 3.8 times, compared to 2.7 times for those with lower literacy (p = 0.006). Conclusion Emphasis on providing an education-based approach at each visit increased health literacy significantly. As expected, health literacy was lowest during the first visit, which we believe is the optimal time to implement educational interventions. Type of study Case Control/Retrospective Comparative Study. Level of evidence Level III

Are Senna based laxatives safe when used as long term treatment for constipation in children?

© 2018 Elsevier Inc. Background and aim: Senna is a stimulant laxative commonly used by pediatricians, pediatric gastroenterologists, and pediatric surgeons. Many clinicians avoid Senna for reasons such as tolerance or side effects but this has little scientific justification. We recently found several patients we were caring for developed perineal blistering during the course of Senna treatment. Because of this we chose to review the literature to identify side effects in children taking this medication as well as to analyze our Center\u27s experience with Senna\u27s secondary effects. Methods: We performed a literature review (MEDLINE, PUBMED) using the keywords of Senna, sen, sennosides and children, and pediatric and functional (idiopathic) constipation. We looked for articles with information regarding perineal blisters related to Senna as well as other secondary effects of Senna laxatives in children when used on a long-term basis. We also reviewed the charts of our patients who had previously taken Senna or are currently taking Senna, looking for adverse reactions. Results: Eight articles in the literature reported perineal blisters after administration of Senna laxatives in 28 patients. Of those occurrences, 18 patients (64%) had accidental administration of Senna and 10 (36%) had Senna prescribed as a long term treatment. All of the blistering episodes were related to high dose, night-time accidents, or intense diarrhea with a long period of stool to skin contact. At our institution, from 2014 to 2017, we prescribed Senna and have recorded data to 640 patients. During the study period, 17 patients (2.2%) developed blisters during their treatment. Patients who developed blisters had higher doses 60 mg/day; 60 [12–100] vs. 17.5 [1.7–150] (p \u3c 0.001). All of the blistering episodes were related to night-time accidents, with a long period of stool to skin contact. 83 (13%) patients presented minor side effects such as abdominal cramping, vomiting or diarrhea which resolved once the type of laxatives were changed or enemas were started. The doses of Senna was not significantly different in these patients 15 mg/day [4.4–150] vs. 17.5 mg/day [1.5–150]. There were no other long-term side effects from Senna found in the pediatric literature for long-term treatment besides abdominal cramping or diarrhea during the first weeks of administration. We found no evidence of tolerance to Senna in our review. Conclusion: There is a paucity of information in the literature regarding side effects of sennosides as a long-term therapy, and to our knowledge, this is the first review of Senna side effects in children. Senna induced dermatitis is rare, but may occur when patients need a higher dose. All of the cases described had a long period of exposure of the skin to stool. Besides the perineal rash with blisters, we could find no other described major side effect with Senna administration in the pediatric population or evidence of the frequently mentioned concern of the development of tolerance to Senna. Pediatric caregivers should advise families of the rare side effect of skin blistering and educate them to change the diaper frequently in children who are not toilet- trained to reduce stool to skin exposure. We can conclude from this review that Senna is a safe treatment option for constipation in children. Level of evidence: IV

Can sacral development as a marker for caudal regression help identify associated urologic anomalies in patients with anorectal malformation?

© 2018 Elsevier Inc. Background and aim: The sacral ratio (SR) is a well-established tool to quantify sacral development in patients with anorectal malformations (ARM) and can be used as a predictor of fecal continence. We hypothesized that a lower SR correlated with the presence of urologic and renal malformations. Methods: We retrospectively reviewed the medical records of patients with ARM treated at our center from 2014 to 2016. We measured the lateral SR as a marker for sacral development and assessed the spine for the presence of tethered cord (TC). Urological and renal anomalies, including single kidney, hydronephrosis, hypospadias, vesicoureteral reflux (VUR), ectopic ureter, and penoscrotal transposition were assessed. Analysis of variance (ANOVA), t-tests, and multivariable linear regression were used to test for differences in SR with consideration of associated urologic malformations and tethered cord. Results: 283 patients with ARM were included for analysis (156 females). The median age was 39 months (10–90). Among these, 178 (55.6%) had 1 or more urologic malformations, and 81 (25.3%) had a TC. Hydronephrosis, high-grade VUR (3–5), solitary kidney, and tethered cord were significantly associated with lower SR (p \u3c 0.01). In multivariable regression models, the presence of urologic abnormalities remained significantly associated with lower a SR despite the presence or absence of TC (p \u3c 0.001). Conclusion: SR is a potentially useful indicator of certain urologic anomalies including hydronephrosis, high grade VUR, and solitary kidney in patients with ARM. This association is independent of the presence of TC. A sacral ratio as a part of the VACTERL screening can help the surgeon identify which patients need closer urologic follow up.
