Introduction: Giggle incontinence is a type of urinary incontinence (GI) that occurs with laughing due to the urinary bladder's involuntary contraction leading to complete emptying. There are studies in the literature that biofeedback therapy or methylphenidate can be effective in the treatment of this condition., Objective: This study aimed to compare the efficacies of biofeedback therapy and methylphenidate treatment in patients with GI., Study Design: In this non-randomized observational study, children aged 5-18 years who were diagnosed with GI between January 2014 and December 2019 were included in the study. Patients who were treated by biofeedback were assigned to Group 1, while patients who were given methylphenidate treatment were placed in Group 2. Patients in Group 1 were treated with biofeedback, which was planned once a week for four weeks and once a month for the following two months. They continued their pelvic floor strengthening exercises at home for the following nine months. Patients in Group 2 were prescribed 5 mg oral methylphenidate qid for three months. Patients in both groups were followed up with 3-month intervals within a year. The results were classified as complete response, partial response or no response as per The International Children's Continence Society (ICCS) recommendations., Results: The study population consisted of 38 patients with GI. Mean age of the patients was 7.7 (5-11). Among these patients, 31 (81.5%) were female, while 7 (18.4%) were male. Two groups were similar regarding mean patient age and gender distribution. There was no difference between the two groups regarding treatment responses evaluated during the 1st, 3rd, and 6th-month outpatient clinic encounters (p > 0.05). However, treatment responses assessed during the 12th-month outpatient clinic encounter revealed 15 (94.1%) patients with complete response in Group 1, while there were 10 (55.6%) patients who showed complete response in Group 2, with a significant difference (p = 0.03)., Discussion: Our study showed that treatment responses were reduced after discontinuation of methylphenidate. We achieved high complete response rates in the first, third, sixth, and twelfth-month assessments by biofeedback treatment., Conclusions: Significantly more favorable treatment outcomes were achieved with biofeedback therapy than methylphenidate treatment after completion of 1-year. Multi-center, randomized studies are needed to evaluate efficacy and safety., Competing Interests: Conflict of interest No conflict of interest was declared by the authors., (Copyright © 2021 Journal of Pediatric Urology Company.

Background: Average long-term outcome after laparoscopic Roux-en-Y gastric bypass is 25% total weight loss. The risk of short-term complications (leakage and bleeding), acute internal herniation, and mortality are 4.0%, 2.5%, and .2%, respectively. There is a paucity of evidence on what patients expect in terms of weight loss and to what extent surgical risks are tolerated., Objective: To examine the patient's weight loss expectations and acceptance of the morbidity and mortality risk after primary laparoscopic Roux-en-Y gastric bypass., Setting: Teaching hospital, Amsterdam, the Netherlands., Methods: Two-hundred patients participated in a standardized survey after completion of an extensive multidisciplinary screening, before surgery. Weight loss expectations, naive assessment, and acceptation of risks of morbidity and mortality were addressed with standard gamble methods., Results: The 200 participants (156 female, 78%) had a mean age of 45.1 years and a mean body mass index of 42.3 kg/m 2 . Weight loss was overestimated by 151 patients (75.5%), and 79 participants (39.5%) were disappointed with the predicted weight loss. Median accepted risks on short-term complications, acute internal herniation, and mortality were 35.8% (interquartile range, 21.0%-58.0%), 25.1% (interquartile range, 15.9%-50.8%), and 4.5% (interquartile range, 1.0%-10.0%), respectively., Conclusion: Patients seeking bariatric surgery seem to have unrealistic weight loss objectives and are willing to accept substantial risks to achieve these goals., (Copyright © 2020 American Society for Bariatric Surgery.

Objectives: Numerous clinical and histopathological characteristics have been associated with malignant transformation (MT) of oral leukoplakia (OL), including classic and differentiated epithelial dysplasia, but MT predictions remain suboptimal. The objective of this study was to determine the annual MT rate of OL and to identify clinicopathological risk factors associated with MT., Patients and Methods: 170 patients with OL were included in this retrospective cohort study, 117 females and 53 males. Follow-up ranged from 12 to 219 months (median 54). The analyzed variables included age, gender, smoking habits, clinical presentation, subsite, size and treatment. In a subgroup of 140 patients, histopathological diagnoses were reviewed with regard to the presence of dysplasia, discerning both classic dysplasia and differentiated dysplasia., Results: MT occurred in 23% of the patients, resulting in an annual MT rate of 4.9% (95% CI: 3.5 - 6.6) which remained consistent. High-risk subsite (tongue and floor of mouth) was the only clinical predictor for MT (Hazard Ratio = 2.7, 95% CI: 1.3 - 5.5, p = 0.007). In 140 patients, classic dysplasia (Hazard Ratio = 7.2, 95% CI: 1.6 - 33.1, p = 0.012) and differentiated dysplasia (Hazard Ratio = 6.6, 95% CI: 1.2 - 25.4, p = 0.026) were predictors for MT. Binary grading between dysplasia and no dysplasia was significant for predicting MT (Hazard Ratio = 6.4, 95% CI: 1.5 - 27.5, p = 0.013)., Conclusion: Since annual MT rate of OL remains stable during follow-up, regular long-term or even life-long follow-up is advocated. Specific oral subsites and epithelial dysplasia are predictors for MT of OL., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.
