Lumbar Disc Herniation in Pediatric

引用

Open Journal of Modern Neurosurgery 2018年第2期8卷 233-238页

作者： Mostafa Abd Elsamea mohamed shaban Ahmed Taha Samer Elshora Neurosurgery Orthopedic Department Faculty of Medicine (Damietta) Al-Azhar University Egypt

Lumbar disc herniation is a common complaint among adults with degenerated lumbar intervertebral discs, however its incidence in childhood and adolescence is abundant. Findings recommended that pediatric lumbar disc herniation is dissimilar in numerous way from that in adults. It was confirmed that pediatric patients respond to conventional management less than adults, also the consequence of the operation continued to be acceptable for at least 10 years after the first surgery even though it seems to decline somewhat. This retrospective study was undertaken to determine the clinical outcome and the feature of lumbar disc prolapse in pediatric patients. 12 patients younger than 18 years were operated for lumbar disc prolapse in the period from 2012-2016. Patients preoperative data and radiological imaging, operative and postoperative follow up were reviewed. 12 patients were included in this study, 10 were male and 2 females, the average age was 15 years (ranging between 12 - 18 years). The average duration of the symptoms was 11 months. The average follow up was 14 months. All patients had a sciatica prior to surgery, 35% had motor deficit, and 60% had parasthesia. Conservative treatment failed in all patients. After surgery and follow up, improvement occurs in about 80% of patients, ranging from excellent to good, and 20% of patients with fair outcome. According to Pain Visual Analogue Scale, leg pain reduced from 90 - 30 and back pain from 80 - 35. Conclusion: Pediatric lumbar disc herniation is an uncommon object leading to hospitalization. About 0.1% - 0.2% of children and adolescence surgery for lumbar disc herniation in pediatric does not lead to chronic back pain or interfere with physical activity and is related to the excellent short consequence.

Effects of TiO2 NTs% on Polyethersulfone/TiO2 NTs Membranes

材料科学与工程（中英文A版） 2015年第1期5卷 65-68页

作者： mohamed shaban Hany Hamdy Heba AbdAllah Lamiaa Said Ahmed Abdel khalek Nanophotonics and Applications Lab Department of Physics Faculty of Science Beni-Suef University Beni-Suef 62514 Egypt Engineering Research Division Chemical Engineering & Pilot Plant Department National Research Center Dokki 12311 Egypt Department of Chemistry Faculty of Science Beni-Suef University Beni-Suef 62514 Egypt

In this work, PES (polyethersulfone)/TiO2 nanotubes membranes were fabricated by a simple and cheap method. The TiO2NTs (titanium dioxide nanotubes) are prepared by the hydrothermal method, the tubes had a narrow size distribution with an average inner diameter of 3-5 nm and outer diameter of 10-13 nm. TiO2NTs blended PES membranes are prepared by phase inversion method with different nanotubes percentage (0.18%-0.85%). The morphology of PES membrane was obviously affected by the addition of TiO2NTs. The prepared membranes were applied on a vacuum desalination system and the desalination results showed that the salt rejection % and permeate flux of the membrane are enhanced through the addition of TiO2NTs. The membrane with higher (0.85%) TiO2NTs content resulted in a decrease of salt rejection % because of the defective membrane structure.

Open Journal of Obstetrics and Gynecology 2022年第6期12卷 510-514页

作者： Adel mohamed Ismail Haitham Abdel Wahab Said shaban Gyneoncology Department Ismailia Teaching Oncology Hospital Ismailia Egypt Gyneoncology Department El-Galaa Maternity Teaching Hospital Cairo Egypt

Introduction: Pyogenic spondylodiscitis is a rare and severe complication of laparoscopic Sacro-Hysteropexy with a polypropylene mesh. The proper and early diagnosis following by medical treatment, if not responding, so we shift to surgical approach is very important to prevent irreversible complications. Case Presentation: A female patient 32 years old admitted to our Gyne-Oncology unit in El-Galaa Maternity Teaching Hospital, in Jan 2022 with a significant weakness in both lower limbs up to complete paralysis, by history she has done a laparoscopic Hystero-Sacro-Pexy with synthetic polypropylene mesh 2 weeks ago, all investigations were normal except WBCs was 14,000 and CRP was 28, MRI Finding was an Encysted collection likely seroma at sacral promontory 4 × 3 cm, surgical removal of the mesh was done, the mesh related to the sacrum was severely infected and pus formation was noticed, 4 hours after the operation there was a Dramatic response and complete resolution of symptoms within few days. Conclusion: Because of the rarity of this complication in the literature, Spondylodiscitis awareness of symptoms, timely diagnosis, and treatment including surgical removal of synthetic mesh after Sacro-Pexy are fundamental to prevent irreversible complications.
