Background Endoscopic third ventriculostomy (ETV) is a widely accepted treatment for obstructive hydrocephalus. For most practitioners, this procedure will be performed without navigation guidance. Without such guidance, the complications associated with the procedure have ranged from 1% to 8%. We hypothesized that the discrepancy between the surface bony anatomy and internal cranial anatomy contributes to the morbidities associated with ETV. Selleckchem Favipiravir We tested this hypothesis by comparing the position of the entry point defined by the classic Kocher's point relative to the ideal entry point that would result in no manipulation of the endoscope defined by frame-based stereotaxis. Methods The cranial computed tomography scan of 58 patients who had undergone frame-based stereotactic ETV was reformatted into 3-dimensional renderings. The location of this entry point was compared with the Kocher point, as determined by the external bony anatomy. Results Overall, >70% of the burr holes that provided an ideal trajectory to the third ventricle were ≥0.5 cm from the Kocher point in both the sagittal and the coronal planes. Median deviations of 0.74 and 0.81 cm in the coronal (P less then 0.01) and sagittal (P less then 0.0001) planes were observed. Conclusion The use of stereotactic endoscopic techniques increase the safety of third ventriculostomy by adding precision and reducing otherwise unnecessary surgical maneuvering.Objective The relationship between urgent decompression and neurologic recovery for traumatic spinal cord injury (TSCI) remains controversial. This meta-analysis was conducted to determine the beneficial effects of surgery within 8 hours for patients with TSCI. Methods A systematic search in EMBASE, MEDLINE, Cochrane Library, and PubMed for relevant studies was conducted from the earliest records until December 2019. Studies that compared outcomes of early ( 0.05). Conclusions This meta-analysis provides evidence of benefits from urgent ( less then 8 hours) decompression for patients with TSCI in terms of neurologic recovery. The improvement effect is more definite in patients with initial complete TSCI.The primo vascular system (PVS) has been difficult to detect due to its small diameter and translucent features of the threadlike network. Thus, the developed methods to find and take out PVS were to use contrast-enhancing dyes including Alcian blue, Trypan blue and Janus green B. To use as a detector to PVS and a biological tool for functional study of PVS, monoclonal antibodies (mAbs) against PVS of rat were generated by various techniques, such as cell fusion, ELISA, Western blotting (WB), screening of hybridoma, immunofluorescence microscopy (IF). Among 16 mAbs generated, 4 representative mAbs were characterized with their specificities in ELISA, WB, and IF. α-rPVS-m1-1 and α-rPVS-m4-6 had strong binding affinities to PVS in both ELISA and WB but did not show specificities at all in IF. On the contrary, α-rPVS-m3-2 and α-rPVS-m3-4 almost did not respond in WB but had strong binding affinities in ELISA and specificities in IF. Two mAbs stained predominantly at extra cellular matrix and cell membrane of PVS of rat in IF. Thus, α-rPVS-m3-2 and α-rPVS-m3-4 can be used as a tool in discriminating PVS from Blood vessel (BV) and lymphatic vessel (LV) and other similar tissues of rat in IF.Background Transverse vaginal septum is a rare Müllerian anomaly that can coexist with other defects. Case A 12-year-old patient was referred to our clinic for cyclic, lower abdominal pain. Magnetic resonance imaging revealed the presence of a transverse vaginal septum, a hemiuterus with a nonfunctioning rudimentary horn, and left unilateral ureter and kidney. The septum was excised laparoscopically assisted by a vaginal dilator to guide the dissection. The mucosal gap of the vagina was then bridged with sutures using the perineal approach. The postoperative course was uneventful and the patient was discharged with instructions for vaginal dilations. Summary and conclusion Early identification of a transverse vaginal septum and careful planning of the operation can improve the outcome of corrective surgery and prevent possible complications.Antimicrobial photodynamic therapy (aPDT), combined or not with antibiotics, constitutes a promising therapy for superficial infections caused by bacteria implicated in multidrug resistance processes. We compared the efficacy of aPDT using the photosensitizer methylene blue (MB), combined or not with the antibiotic gentamicin (GN), against Staphylococcus aureus and Pseudomonas aeruginosa. Different concentrations of MB (0.03-7000 μg/ml), with or without GN (1-20 μg/ml), were added to planktonic cultures or biofilms and the samples irradiated with a LED lamp (λ 625 nm, 7 mW/cm2, 18 J/cm2). The number of viable bacteria in the samples and in corresponding nonirradiated controls was quantified by counting colony-forming units to evaluate the individual effects of MB, GN, and irradiation. MB-aPDT resulted in significant bacterial photoinactivation. The combination of GN and MB-aPDT exerted a synergistic bactericidal effect against planktonic cultures of S. aureus and P. aeruginosa. This combination did not significantly alter the photoinactivating effect of MB against S. aureus biofilms, but exerted a positive bactericidal effect against P. aeruginosa biofilms. These results underscore the need for further clinical studies of this therapeutic combination for the management of difficult-to-treat skin and mucous infections, especially those caused by P. aeruginosa.In this meticulous research work, principles and techniques of green chemistry were implemented which exploits environmentally and economically friendly method using effortless, accessible and non-toxic medium that is water and ascorbic acid (Vit.C) which leads to the synthesis of silver/ copper oxide (Ag/CuO) nanocomposite. Vit.C was used to furnish the synthesis of excellent and controlled crystalline silver nanoparticles (AgNPs), copper oxide (CuO) and Ag/CuO nanocomposite. Moreover, the structures of all the synthesized nanomaterials were confirmed by wide range of characterization techniques which include UV-Vis spectroscopy, FTIR, X-ray diffraction and Electron Diffraction Spectroscopy. However external and internal morphology of newly synthesized nanomaterials were examined by using Scanning Electron Microscopy and High resolution Transmission Electron Microscopy, respectively. The prepared nanomaterials were evaluated for catalytic decomposition of methyl orange (MO) in dark, visible light and UV light.
