“…Difficulties in mathematics accompany children during adolescence, in their transition to secondary education, where they are expected to add new and more complex subjects, such as calculus trigonometry and algebra, to their already existing knowledge of arithmetic [31], while they already present weaknessesincomprehending decimals and fractions [32]. In addition, adolescents have difficulty with clearly writing numbers and correctly placing themto the corresponding columns, calculating money, finding alternative ways to solve a math problem, measuring ingredients, drawing information from charts and maps and understanding the place value [33].All of these mathematical concepts require the same underlying cognitive processes involved in othermathematical subjects (such as algebra and fractions), most of which are deficient in children with SLD [34].…”

SLI and SLD constitute two autonomous neurodevelopmental disorders, which frequently cause challenges in the diagnosis process, especially due to their nature, which has caused disagreement among clinicians regarding their recognition as separate or overlapping disorders. The objective of the study was to enlighten the path of valid diagnosis and intervention during adolescence when the two disorders change their manifestation and overlap. 200 Greek adolescents (140 boys and 60 girls), 124 already diagnosed with SLD and 76 diagnosed with SLI, 12-16 years old, participated in the study. All participants were assessed in reading, oral and written language and mathematics (mathematical operations and mathematical reasoning) along with IQ testing. In order to determine statistically significant differences, the chi-square test, independent samples t-test, odd ratios and their 95 per cent confidence intervals were implemented. The results revealed that the SLI group presented significantly greater difficulties than SLD in their overall cognitive-mental profile and in most language and mathematical measurements (number concept, executive-procedural part of solving operations and mathematical reasoning). The similarity of the two groups was mainly detected in their deficient metacognitive, metalinguistic and metamnemonic strategies. The research concludes that SLD adolescents managed to overcome their difficulties to a significant degree, while adolescents with SLI still struggle with many learning areas.

Laparoscopic Transperitoneal Repair of Retrocaval Ureter: Case Report

2019

View full text Add to dashboard Cite

Introduction: Retrocaval ureter is an uncommon clinical entity that generally causes upper urinary tract obstruction on the right side as the right ureter courses posterior to the inferior vena cava. 1 The main therapeutic approach for this disease is surgical repair. 2 This video describes the operative technique for laparoscopic repair of a retrocaval ureter. Case Presentation: The video shows the technique for a laparoscopic transperitoneal ureteroureterostomy in a 28-year-old female. The patient was admitted to the hospital with intermittent right flank pain and right hydronephrosis on ultrasonography. Further diagnostic imaging with a CT revealed proximal ureteral obstruction caused by retrocaval placement of the ureter. A laparoscopic repair of retrocaval ureter was planned. Initially, the inferior vena cava and proximal ureter were dissected until the proximal ureter was totally mobilized. The distal ureter was circumferentially dissected as well. The ureter was then divided and replaced in its normal anterior-caval position. A ureteroureteral anastomosis was performed with 4-0 polyglactin suture over a Double J-ureteral stent. The surgery was completed in 160 minutes. No intraoperative or postoperative complications occurred. 3 Oral intake and mobilization of the patient were started 6 and 24 hours, respectively, after the surgery. The drain was removed after 48 hours and the patient was discharged on postoperative day 3. The Double J-stent was removed at 6 weeks postoperatively. Postoperative 4th week CT urography imaging showed a normal course of the right ureter with diminished hydronephrosis. Follow-up was uneventful at 6 months postoperatively. Conclusion: The classical treatment for retrocaval ureter is replacing the ureter in its natural anatomic position with an open ureteroureterostomy. A laparoscopic approach for retrocaval ureter is an alternative to the open surgery with several benefits such as reduced pain, shorter hospital stay, and better cosmetic results. No competing financial interests exist. Runtime of video: 7 mins 25 secs
