RESUMO

Background: Atopic dermatitis (AD) is a chronic dermatological condition, often diagnosed and managed by pediatricians. However, pediatricians have difficulties with adhering to guidelines, which recommend the use of topical corticosteroids (TCS) as a first-line treatment and oral corticosteroids (OCS) for resistant cases. Our aim was to assess pediatricians' self-confidence in using steroids in the management of pediatric AD, and investigate which characteristics are related to high self-confidence in prescribing corticosteroids (CS). Methods: We conducted a cross-sectional questionnaire study among Israeli pediatricians between April 2022 and June 2022. Participants were asked to answer questions dealing with self-assessment of prescribing CS in the management of AD. Results: A total of 171 residents and pediatricians participated in the survey; 86.6% and 28.1% admitted feeling either average or below-average confidence in the prescription of OCS and TCS, respectively. Physicians who were exposed to higher AD patients (P=0.048) and worked at the clinics (88.2% vs. 60.4%, P<0.001) had high self-confidence in treating AD with TCS. Males (20.3% vs. 8%, P=0.03), and having gone to medical school outside Israel (22.2% vs. 10.4%, P=0.09) were all related to high self-efficacy in prescribing OCS. In total, 11.7% of participants confessed to refraining from prescribing steroids because of fear of side effects. Conclusions: Most pediatricians have below-average confidence in prescribing OCS for the treatment of AD. Males, working in a community setting, and previous exposure improve the confidence level and can be easily considered in future pediatric training programs.

RESUMO

Background: Pediatricians daily see large numbers of patients with skin disorders. However, they encounter limited guidance as a result of a marked deficiency in pediatric dermatologists. Hence, reevaluation of training opportunities during pediatric residency has become essential. Our aim was to evaluate the confidence level of pediatric residents and specialists in diagnosing and treating skin disorders in children and to determine career and training-related characteristics that influence it. Methods: Conducted as a cross-sectional study, we administered a questionnaire to 171 pediatricians across Israel. We assessed respondents' self-efficacy about their ability to diagnose and treat skin disorders and collected data regarding their previous dermatology training and preferred training methods. Results: 77.8% of respondents reported below or average self-efficacy scores in diagnosing and managing children with skin disorders. Older age (>40 years old; OR = 5.51, p = 0.019), treating a higher number of patients with skin disorders (OR = 2.96, p = 0.032), and having any training in dermatology, either during medical school or residency (OR = 7.16, p = 0.031, OR = 11.14, p = 0.003 respectively), were all significant parameters involved in pediatricians reporting high self-efficacy in skin disorder management. Conclusion: Most pediatric residents and pediatricians have average or below-average confidence in managing pediatric skin disorders. We suggest incorporating dermatology rotations during pediatric residency to improve young pediatricians' self-efficacy in managing skin disorders and ultimately help pediatricians provide better care for patients presenting with dermatological conditions. These findings can ultimately help refine a pilot program in dermatology that might be implemented during pediatric residency.

RESUMO

Atopic dermatitis (AD) is one of childhood's most common skin conditions. Although pediatricians often diagnose and manage it, more than half refer even mild cases to dermatologists. In this study, we aimed to evaluate pediatric residents' and pediatricians' self-confidence regarding their ability to diagnose and manage AD. A cross-sectional questionnaire study was conducted with Israeli pediatric residents and pediatricians in 2022. The questionnaire was designed to distinguish participants with high vs. low self-confidence characteristics regarding their ability to diagnose and treat AD. In total, 171 participants completed the questionnaire (59.4% women; age, 41.1 ± 10.6 years); 39.1% of the participants were residents, while 60.9% were board-certified pediatricians. Overall, 64.4% of the responders reported below or average confidence (score ≤ 3, on a scale of 1-5) in diagnosing and treating AD in children. The group with higher self-confidence was significantly older (44.39 vs. 39.14 years, P = 0.003), had more years of experience in evaluating pediatric AD (P = 0.004), had trained in dermatology during their residency (P = 0.02) with a longer training period (P = 0.01), and with more than three training methods (P = 0.009). Multivariable logistic regression analysis showed that high self-confidence was associated with age older than 40 years and training in dermatology during residency (odds ratios = 5.63 [P = 0.04] and 3.36 [P = 0.05], respectively).  Conclusion: Most pediatric residents and pediatricians were not particularly confident in treating children with AD. Those with high self-confidence were older, had been exposed to more patients, and had been trained in dermatology during their residency with various methods and for longer periods. Therefore, we encourage the implementation of a training program in dermatology during pediatric residency programs. What is Known: • Atopic dermatitis (AD) is one of childhood's most common skin conditions and often presents to pediatricians for diagnosis and management. • Many pediatricians refer children with even mild cases of AD to dermatologists. What is New: • Most pediatric residents and pediatricians report low confidence in diagnosing and treating pediatric AD. • Physicians with high self- confidence were older, exposed to more AD patients, and had been trained in dermatology during their residency with various methods and for longer periods. Therefore, the implementation of a training program in dermatology during pediatric residency programs is warranted.

RESUMO

OBJECTIVE: Since women with GDM have an increased risk to develop type 2 DM, a 75 g OGTT is recommended 6-12 weeks postpartum for all women with GDM. However, screening rates remain low. The aim of this study was to find factors affect the rate of postpartum DM screening. MATERIALS AND METHODS: A retrospective cohort study between 2016 and 2017 at the Soroka Medical Center, comparing women with GDM who underwent postpartum DM screening test to those who did not. RESULTS: 257 women who had a diagnosis of GDM and met the inclusion criteria were included. 53 (20.6%) had a postpartum DM screening test and 204 (79.4%) did not complete the postpartum DM screening. Women who underwent a DM screening postpartum were more likely to be older, with significantly higher rates of vacuum-assisted delivery, more likely to be diagnosed with GDMA2 as compared to GDMA1 during pregnancy and, with high probability of receiving recommendations for screening at a postpartum visit. CONCLUSIONS: The rates of postpartum DM screening for women with GDM are low and need to increase. Age greater than 25, vacuum delivery, GDMA2, and having received a recommendation for postpartum screening increased the likelihood of undergoing a postpartum DM screening.

RESUMO

BACKGROUND: Pelvic floor dysfunction (PFD) most commonly results from weakened or injured muscles and ligaments whose purpose is to support the pelvic floor. Many studies have placed vaginal delivery and prolonged second stage of labor (SSL) as major risk factors for PFD, supposedly through generating enhanced pressure in the pelvic area. Although many studies describe the effects of vaginal delivery and labor on structure and function of the pelvic floor, not much is known regarding PFD deriving from pregnancy and its prevalence and severity in the postpartum. We aimed to evaluate whether a correlation exists between PFD symptoms during pregnancy and the duration of the SSL. METHODS: We conducted a cross sectional study of 200 women who gave birth at Soroka University Medical Center, Beer-Sheva, Israel. Those who had consented completed the Pelvic Floor Distress Inventory-20 (PFDI-20), a condition specific questionnaire developed to measure quality-of-life and the extent of injury to the pelvic floor in women with all forms of PFD. The duration of the SSL and clinical and obstetrical characteristics were retrieved from the participants' medical records. We assessed correlations using Spearman's correlation coefficient. RESULTS: PFD during pregnancy was found to be correlated to the duration of the SSL (R = -0.183, p = .021). When evaluating each component of the PFDI-20 separately, CRAD was significantly correlated with the duration of the SSL (R = -0.195, p = .014). CONCLUSIONS: There is a correlation between PFD symptoms during pregnancy, specifically symptoms of CRAD and the duration of the SSL.

RESUMO

Ectopic pregnancy (EP) occurs in approximately 2% of all pregnancies. A common method of treatment is methotrexate therapy, considered in haemodynamically stable patients. Endometrial thickness has been investigated as a tool for diagnosing EP. The objective of this study was to evaluate the association between endometrial thickness and the criteria for MTX treatment, in an attempt to facilitate outcome prediction. We retrospectively collected data from records of patients diagnosed with EP between 2012 and 2014 including information regarding the mode of treatment and outcome. The endometrial thickness was compared between cases that met the criteria for MTX treatment and those who did not. Of 267 cases of EP that were reviewed, 108 patients were treated with MTX. The MTX treatment success rate was 88%. Endometrial thickness was found to be significantly and inversely associated with criteria for MTX treatment. In conclusion, an association was found between the endometrial thickness and the criteria for selection of MTX treatment for EP. This may be a useful tool in treatment selection for EP.Impact StatementWhat is already known on this subject? Transvaginal sonography along with ß-human chorionic gonadotrophin (ß-hCG) monitoring is the standard for evaluation of suspected ectopic pregnancy (EP). The most specific sonographic finding for EP is the presence of a live extra uterine pregnancy. In research conducted with the purpose of finding intrauterine sonographic findings associated with EP, this condition has been shown to be correlated with a thinner endometrial lining, compared with that of an intrauterine pregnancy.What the results of this study add? The results of this study add information on the subject of methotrexate treatment success rates in correlation with the endometrial thickness.What the implications are of these findings for clinical practice and/or further research? The findings of this study contribute to the process of treatment selection for ectopic pregnancy by emphasising the association between a thick endometrium and the lower success rates of MTX treatment.

RESUMO

Introduction: Instrumental delivery is a well-known risk factor for obstetric anal sphincter injuries (OASIS). The specific characteristics among patient undergoing vacuum extraction delivery (VE) are less studied. Therefore, we aimed to evaluate risk factors for OASIS among parturient that underwent a VE delivery in a large university affiliated maternity hospital.Material and methods: The study population contained 9116 women who delivered by VE in tertiary medical center from 1988 to 2015. Inclusion criteria included deliveries beyond 24-week gestation. Multiple gestations and pregnancies complicated with stillbirth were excluded from the analysis. Maternal obstetric variables were compared between parturient with and without OASIS. Independent risk factors for OASIS were assessed by multivariable logistic regression modeling.Results: OASIS was diagnosed in 94 women (1.03%) following vacuum extraction. Among patients who underwent a VE delivery, gravidity and parity were found to be significantly lower in patients with OASIS. A multivariable logistic regression model with OASIS as the outcome variable revealed that among women who underwent VE, while episiotomy and delivery of a macrosomic neonate were not independently associated with OASIS, a strong association between nulliparity and OASIS was found (OR 3.34; 95% CI 1.93-5.78; p < .001).Conclusions: OASIS is uncommon in our population. Vacuum extraction in nulliparous parturient is a significant risk factor for OASIS. Our results should be taken into account when managing nulliparous deliveries.

RESUMO

AIMS: We aimed to investigate the impact of Gestational Diabetes Mellitus (GDM) complications on compliance with postpartum Diabetes screening. METHODS: A retrospective cohort study was conducted comparing screening rates of women with and without GDM associated complications who delivered at the Soroka University Medical Center, between 2016 and 2017. The screening test of choice was a 2-hour 75 g oral glucose tolerance test, taken 6-12 weeks after delivery. GDM associated complications included one or more of the following: polyhydramnios, macrosomia, shoulder dystocia or cesarean section. Univariate analysis was used in order to examine if GDM associated complications were associated with postpartum diabetes screening. RESULTS: During the study period a 164 women were included, of which, 82 women had suffered from GDM associated complications and comprised the study group and 82 women with GDM but without complications comprised the comparison group. Women in the study group were significantly older with a higher parity order. Induction rates were significantly higher among the comparison group, whereas, cesarean section rates were higher among the study group. No difference was noted with regard to neonatal outcomes. Women in the study group were not found to be more likely to be given screening recommendations at discharge (P = 0.50), at their postpartum visit (P = 0.36) or to perform DM screening postpartum (P = 0.17). CONCLUSION: Women with GDM associated complications had a higher rate of compliance to postpartum DM screening recommendations. However, in the current study this difference did not reach statistical significance.

RESUMO

BACKGROUND: To compare the short- and long-term outcomes in patients with and without intraoperative spillage from benign adnexal masses during laparoscopic removal. METHODS: We conducted a retrospective analysis of all cases of laparoscopic removal of ovarian cysts (cystectomy or adnexectomy) in our institution between the years 2013 and 2017, excluding malignant lesions. RESULTS: During the study period, 186 cases of ovarian cyst removal were identified. Intraoperative ovarian cyst spillage (IOCS) occurred in 104 cases (study group), while in the remaining 82 cases no spillage was reported (control group). Baseline clinical characteristics were comparable between groups. Large cyst diameter and intraperitoneal adhesions were significantly associated with the occurrence of IOCS (P  = 0.008 and < 0.001, respectively). The use of an endoscopic retrieval bag was significantly inversely associated with IOCS. Postoperative complications (pain score, hospital stay, febrile illness and recurrence of ovarian cyst) were comparable between groups. CONCLUSIONS: IOCS during laparoscopic cystectomy is associated with larger cyst diameter and intraperitoneal adhesions, but not with adverse short- or long-term outcomes nor with recurrence rates.

RESUMO

PURPOSE: Pregnancy and labor are known risk factors for pelvic floor dysfunction (PFD). Yet not much is known regarding recovery from PFD. We hypothesized that the recovery from PFD during the postpartum period would be associated with the duration of the second stage of labor (SSL). METHODS: We conducted a case-control study of patients who gave birth at the Soroka University Medical Center, Beer-Sheva, Israel. Those who consented completed the Pelvic Floor Distress Inventory-20 (PFDI-20), a questionnaire developed to measure the extent of injury to the pelvic floor, after delivery and 3-month postpartum. The difference between the scores was calculated, representing recovery of symptoms. The duration of the SSL, and clinical and obstetrical characteristics were retrieved from the patients' medical records. Wilcoxon rank test was used, assessing the significance of the recovery. The association between the degree of the recovery and the duration of SSL was tested using Mann-Whitney ranking. RESULTS: A total of 92 patients completed the PFDI-20 after delivery and 3-month postpartum. We found a significant difference between PFD symptoms during pregnancy and 3-month postpartum (P < 0.001). This difference remained consistent in all components of the PFDI-20. In addition, a more profound recovery of colorectal and anal dysfunction (CRAD) symptoms was associated with a shorter duration of the SSL (P = 0.03). CONCLUSIONS: There is a statistically significant recovery of PFD symptoms in the postpartum period. Furthermore, greater recovery from CRAD symptoms is associated with a shorter duration of the SSL.

RESUMO

BACKGROUND: The serologic status of patients with ulcerative colitis (UC) who develop postoperative pouchitis was compared with that of patients with Crohn's disease (CD) and unoperated patients with UC. METHODS: Pouch patients were stratified into normal pouch, acute/recurrent acute pouchitis, and chronic pouchitis/Crohn's-like disease of the pouch groups. Antibodies against glycans associated with CD (anti-Saccharomyces cerevisiae, anti-laminaribioside, anti-chitobioside, and anti-mannobioside carbohydrate antibodies [ASCA, ALCA, ACCA, and AMCA, respectively]) were detected and correlated with type of inflammatory bowel disease and pouch behavior. RESULTS: A total of 501 patients with inflammatory bowel diseases were recruited: 250 (50%) CD, 124 (24.7%) unoperated UC, and 127 (25.3%) UC-pouch. At least 1 positive antibody was detected in 77.6% CD, 52.0% UC-pouch and 33.1% unoperated UC (P < 0.0001 for all). ACCA and AMCA prevalence in CD, UC-pouch and unoperated patients with UC were 33.2%, 24.4%, and 16.9% (P = 0.003 for all) and 35.2%, 26.8%, and 7.3%, respectively (P < 0.0001 for all). ALCA and ASCA were more prevalent in patients with CD than unoperated UC and UC-pouch patients. A longer interval since pouch surgery was associated with inflammatory pouch behavior: 12.45, 11.39, and 8.5 years for acute/recurrent acute pouchitis, chronic pouchitis/Crohn's-like disease of the pouch, and normal pouch, respectively, P = 0.01 for all. CONCLUSIONS: The prevalence of the CD-associated anti-glycan antibodies ACCA and AMCA is significantly increased in UC-pouch patients, suggesting that pouch surgery may trigger differential immune responses to glycans. The finding that the serology of UC-pouch patients shares similarities with that of patients with CD supports the notion that those 2 inflammatory bowel diseases share a common pathogenic pathway.

RESUMO

BACKGROUND & AIMS: Pouchitis is a common long-term complication in patients with ulcerative colitis (UC) undergoing proctocolectomy with ileal pouch-anal anastomosis. Because the inflammation occurs in a previously normal small bowel, studies of this process might provide information about the development of Crohn's disease. Little is known about the intestinal microbiome of patients with pouchitis. We investigated whether specific bacterial populations correlate with the pouch disease phenotype and inflammatory activity. METHODS: We performed a prospective study of patients with UC who underwent pouch surgery (N = 131) from 1981 through 2012 and were followed at Tel Aviv Medical Center. Patients were assigned to groups based on their degree and type of pouch inflammation. Patients with familial adenomatous polyposis after pouch surgery (n = 9), individuals with intact colons undergoing surveillance colonoscopy (n = 10), and patients with UC who did not undergo surgery (n = 9) served as controls. We collected demographic and disease activity data (based on the Pouchitis Disease Activity Index) and measured levels of C-reactive protein. Fecal samples were collected, levels of calprotectin were measured, and microbiota were analyzed by 16S ribosomal RNA gene amplicon pyrosequencing. RESULTS: Increased proportions of the Fusobacteriaceae family correlated with increased disease activity and levels of C-reactive protein in patients with UC who underwent pouch surgery. In contrast, proportions of Faecalibacterium were reduced in patients with pouchitis vs controls; there was a negative correlation between proportion of Faecalibacterium and level of C-reactive protein. There was an association between antibiotic treatment, but not biologic or immunomodulatory therapy, with reduced proportions of 11 genera and with increased proportions of Enterococcus and Enterobacteriaceae. CONCLUSIONS: Reductions in protective bacteria and increases in inflammatory bacteria are associated with pouch inflammation in patients with UC who underwent pouch surgery. The finding that antibiotics exacerbate dysbiosis indicates that these drugs might not provide long-term benefit for patients with pouchitis. Additional studies of this form of dysbiosis could provide information about the pathogenesis of Crohn's disease.

RESUMO

BACKGROUND: Infliximab (IFX) is effective therapy for ulcerative colitis and Crohn's disease, but it may be associated with side effects and loss of response. One loss of response mechanism is increased IFX clearance (IFX-CL), resulting in short half-life and decreased troughs. METHODS: Patients were recruited, and relevant demographic, clinical, and laboratory data were recorded. IFX serum concentrations and antibodies against IFX (ATI) were measured for therapeutic drug monitoring and modeled using NONMEM. RESULTS: There were 169 IFX concentrations (Crohn's disease = 73, ulcerative colitis = 92, and diagnosis undetermined = 4). Patient factors significantly associated with high IFX-CL were low albumin, high body weight, and the presence of ATI (P ≤ 0.001). Disease type did not affect IFX-CL. The typical IFX-CL was 0.381 L/d. ATI formation was associated with a 259% increase in IFX-CL. The estimated median IFX effective half-life was 5.6 ± 2.4 days. Patients with low weight are more likely to have low troughs because IFX CL is not linearly related to weight, but IFX dosing is weight-based (in mg/kg). Simulations investigating alternative dose strategies suggested that more reliably measurable concentrations over the dose interval were achieved when the dose interval was shortened than by increasing administered dose. CONCLUSIONS: IFX-CL is significantly influenced by patient factors, specifically, albumin, body weight, and ATI. There should be a decreasing IFX dose interval strategy, particularly for low albumin patients. Higher starting doses may benefit low body weight patients. Pharmacokinetic models and therapeutic drug monitoring may ensure that patients maintain measurable concentrations throughout dose intervals. Individualized dosing may improve outcomes for IFX-treated patients with Crohn's disease and ulcerative colitis.

RESUMO

BACKGROUND AND AIMS: The Crohn's disease (CD)-specific pancreatic auto-antibodies (PAB), have been recently identified to target glycoprotein 2 (GP2). Pouchitis is an inflammation of the small bowel developing in up to 60% of ulcerative colitis patients undergoing proctocolectomy and ileal pouch anal anastomosis. Occurrence of CD-specific antibodies was reported to be a predictor of pouchitis. We aimed to assess the prevalence of anti-GP2 antibodies (anti-GP2) in the serum and feces of pouch patients and to correlate them with clinical parameters. Furthermore, we examined mucosal expression of the GP2 protein in the pouch. METHODS: Pouch patients were prospectively recruited and checked for clinical, endoscopic, and laboratory markers of inflammation. IgG and IgA anti-GP2 levels in serum and fecal samples were determined using ELISA. GP2 protein was assessed by immunohistochemistry. RESULTS: Anti-GP2 was elevated in both serum and fecal samples of patients with inflamed compared to those with non-inflamed pouches and patients with familial-adenomatous polyposis after surgery (p<0.05, respectively). Moreover, patients with CD-like complications exhibited significantly higher anti-GP2 titers than those without CD-like complications (p≤0.01). High levels of anti-GP2 correlated with more frequent bowel movements per day and with the presence of at least one anti-glycan antibody (p≤0.05). GP2 itself was more abundant in the mucosa of patients with chronic pouchitis. CONCLUSIONS: Anti-GP2 exists in the serum and feces of pouch patients and correlates with pouch inflammation, and presence of other serological markers. Thus, anti-GP2 may contribute to better stratification of pouchitis, more-so when the inflammation exhibits CD-like complications.
