Robotic Posterior Capsule Polishing by Optical Coherence Tomography Image Guidance

xlomafota13 shared this article with you from Inoreader Robotic Posterior Capsule Polishing by Optical Coherence Tomography Image Guidance Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Background In cataract surgery, polishing of the posterior capsule (PC) can lead to improved surgical outcomes but is currently avoided due to its high‐risk nature. This work developed a robotic system capable of performing PC polishing on ex vivo pig eyes using optical coherence tomography (OCT) guidance. Methods The lenses of five ex vivo pig eyes were extracted and a thin layer of glue deposited onto the PC. Transpupillary OCT scans of the anterior segment were used to generate a PC‐polishing trajectory. During polishing, OCT B‐scans tracked the tool tip and were displayed to the operator. Results Complete removal of the glue was accomplished in all five trials with no PC rupture reported. Conclusions The feasibility of using a robotic system guided by OCT to perform PC polishing on a biological model was demonstrated. Contributions include modeling of the PC anatomy, intraoperative OCT visualization, and automated tool‐tip motion with scheduled aspiration pressures. This article is protected by copyright.

Impact of subspecialty training on management of laryngopharyngeal reflux: results of a worldwide survey

xlomafota13 shared this article with you from Inoreader Impact of subspecialty training on management of laryngopharyngeal reflux: results of a worldwide survey Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Feb 27. doi: 10.1007/s00405-021-06710-y. Online ahead of print. ABSTRACT OBJECTIVE: To study the management of laryngopharyngeal reflux (LPR) among the subspecialties of practicing otolaryngology-head and neck surgeons and their trainees. METHODS: A survey was sent to over 8000 otolaryngologists (OTOHNS) over 65 countries, utilizing membership lists of participating otolaryngological societies. The outcomes were answers to questions regarding LPR knowledge and practice patterns, and included queries about its definition, prevalence, clinical presentation, diagnosis, and treatment. RESULTS: Of the 824 respondents, 658 practiced in one specific otolaryngologic subspecialty. The symptoms and findings thought to be the most related to LPR varied significantly between subspecialists. Extra-laryngeal findings were considered less by laryngologists while more experienced OTOHNS did not often conside r digestive complaints. Compared with colleagues, otologists, rhinologists and laryngologists were less aware of the involvement of LPR in otological, rhinological and laryngological disorders, respectively. Irrespective of subspecialty, OTOHNS consider symptoms and signs and a positive response to empirical therapeutic trial to establish a LPR diagnosis. Awareness regarding the usefulness of impedance pH-studies is low in all groups. The therapeutic approach significantly varies between groups, although all were in agreement for the treatment duration. The management of non-responder patients demonstrated significant differences among laryngologists who performed additional examinations. The majority of participants (37.1%) admitted to being less than knowledgeable about LPR management. CONCLUSIONS: LPR knowledge and management vary significantly across otolaryngology subspecialties. International guidelines on LPR management appear necessary to improve knowledge and manageme nt of LPR across all subspecialties of otolaryngology.

Preparation and validation of cyclodextrin-based excipients for radioiodinated hypericin applied in a targeted cancer radiotherapy

xlomafota13 shared this article with you from Inoreader Preparation and validation of cyclodextrin-based excipients for radioiodinated hypericin applied in a targeted cancer radiotherapy Via radioactive iodine Int J Pharm. 2021 Feb 24:120393. doi: 10.1016/j.ijpharm.2021.120393. Online ahead of print. ABSTRACT BACKGROUND: Iodine-131 labeled hypericin (131I-Hyp) has been utilized as a necrosis-avid theragnostic tracer in a dual targeting pan-anticancer strategy called OncoCiDia. Widespread use of previously-tested solvent dimethyl sulfoxide (DMSO) is limited by safety concerns. To tackle this, the present study was designed to explore a clinically feasible excipient for the form ulation of the hydrophobic 131I-Hyp for intravenous administration. METHOD: Solubility of Hyp in serial solutions of already-approved hydroxypropyl-β-cyclodextrin (HP-β-CD) was evaluated by UVspectrophotometry and 50% HP-β-CD was chosen for further experiments. Two novel HP-β-CD-based formulations of 131I-Hyp were compared with previous DMSO-based formulation, with regards to necrosis-targetability and biodistribution, by magnetic resonance imaging, single-photon emission computed tomography (SPECT), gamma counting, autoradiography, fluorescence microscopy and histopathology. RESULTS: Hyp solubility was enhanced with increasing HP-β-CD concentrations. The radiochemical purity of 131I-Hyp was higher than 90% in all formulations. The necrosis-targetability of 131I-Hyp in the novel formulations was confirmed in vivo by SPECT and in vitro by autoradiography, fluorescence microscopy and histopathology. The plasma clearance of r adioactivity was faster in the novel formulations. CONCLUSION: The novel 131I-Hyp formulations with HP-β-CD could be a suitable pharmaceutical excipient for 131I-Hyp for intravenous administration.

Remote medulla ablongata ventral acute subarachnoid hemorrhage following cervical spinal surgery: A case report

xlomafota13 shared this article with you from Inoreader Remote medulla ablongata ventral acute subarachnoid hemorrhage following cervical spinal surgery: A case report Via leak of cerebrospinal fluid Int J Surg Case Rep. 2021 Feb 22;80:105675. doi: 10.1016/j.ijscr.2021.105675. Online ahead of print. ABSTRACT INTRODUCTION: The incidence of remote intracranial hemorrhage (RICH) in patients during spinal surgery is rare and the detailed mechanism remains unclear. PRESENTATION OF CASE: A 55-year-old man had undergone cervical discectomy and fusion at C5-6 and C6-7 due to herniated disc and secondary spinal canal stenosis. He had severe headache 20 h postoperatively and his drain output increased from 100 to 350 mL in the second 10 h after surgery. Computed tomography (CT) and magnetic resonance imaging (MRI) were performed and he was diagnosed with acute subarachnoid hemorrhage in the ventral medulla oblongata. The drainage tube was quickly removed. Infusion of hypertonic saline was used to reduce intracranial pressure and nimodipine prevented vasospasm around the brainstem. The patient made a gradual, satisfactory recovery with conserv ative treatment. DISCUSSION: The most likely pathomechanism leading to RICH is venous bleeding due to rapid leak of a large amount of cerebral spinal fluid (CSF) after spinal surgery. If the patient has a headache or neurological complaints after spinal surgery, immediate imaging is recommended to confirm the diagnosis. Treatment depends on the amount and location of intracranial hemorrhage. CONCLUSION: RICH is a serious but rare complication of spinal surgery and cerebellar hemorrhage is the most common. The most important pathomechanism leading to RICH after spinal surgery is venous bleeding due to rapid leak of a large amount of CSF. Timely CT is necessary to exclude RICH. Treatment of RICH depends on the size of the intracranial hematoma and the patient's symptoms. PMID:33639502 | DOI:10.1016/j.ijscr.2021.105675 View on the web Inoreader.

Early transcriptional changes after UVB treatment in atopic dermatitis include inverse regulation of IL‐36γ and IL‐37

xlomafota13 shared this article with you from Inoreader Early transcriptional changes after UVB treatment in atopic dermatitis include inverse regulation of IL‐36γ and IL‐37 Via Experimental Dermatology Abstract Phototherapy with narrow‐band Ultraviolet B (nb‐UVB) is a major therapeutic option in atopic dermatitis (AD), yet knowledge of the early molecular responses to this treatment is lacking. The objective of this study was to map the early transcriptional changes in AD skin in response to nb‐UVB treatment. Adult patients (n = 16) with AD were included in the study and scored with validated scoring tools. AD skin was irradiated with local nb‐UVB on day 0, 2 and 4. Skin biopsies were taken before and after treatment (day 0 and 7) and analysed for genome‐wide modulation of transcription. When examining the early response after three local UVB treatments, gene expression analysis revealed 77 significantly modulated transcripts (30 down‐ and 47 upregulated). Among them were transcripts related to the inflammatory response, melanin synthesis, keratinization and epidermal structure. Interestingly, the pro‐inflammatory cytokine IL‐36γ was reduced after treatm ent, while the anti‐inflammatory cytokine IL‐37 increased after treatment with nb‐UVB. There was also a modulation of several other mediators involved in inflammation, among them defensins and S100 proteins. This is the first study of early transcriptomic changes in AD skin in response to nb‐UVB. We reveal robust modulation of a small group of inflammatory and anti‐inflammatory targets, including the IL‐1 family members IL36γ and IL‐37, which is evident before any detectable changes in skin morphology or immune cell infiltrates. These findings provide important clues to the molecular mechanisms behind the treatment response and shed light on new potential treatment targets. View on the web Inoreader.

A Systematic Review of the Omohyoid Muscle Syndrome (OMS): Clinical Presentation, Diagnosis, and Treatment Options

xlomafota13 shared this article with you from Inoreader A Systematic Review of the Omohyoid Muscle Syndrome (OMS): Clinical Presentation, Diagnosis, and Treatment Options Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Feb 25:3489421995037. doi: 10.1177/0003489421995037. Online ahead of print. ABSTRACT OBJECTIVE: Omohyoid muscle syndrome (OMS) is a condition that causes a X-shaped lateral neck lump on swallowing, caused by the failure of the central tendon of the omohyoid muscle to restrict movement of the muscle during swallowing. We aim to review the etiology, pathophysiology, diagnostic tests, and management options for this condition. DATA SOURCES: Pubmed, MEDLINE, EMBASE, and Cochrane databases were searched for all articles and abstracts related to OMS up to 29th July 2020. REVIEW METHODS: A systematic review was performed, data extracted from relevant full text articles. Both quantitative data and qualitative data were analyzed. RESULTS: Twenty cases of OMS were reported. Patients presented at a mean age of 36.0. All cases were Asian. There is a 7:3 ratio of males to females. The most common symptom was a transient neck mass. Most cases were managed conservatively with good prognosis. Open or endoscopic transection of the muscle and ultrasound-guided botulinum toxin injection were 3 treatment options, with no recurrence at 4 years, 6 months, and 6 months respectively. CONCLUSION: OMS could be genetic as all cases were Asian in ethnicity. The deep cervical fascia which usually envelopes the omohyoid muscle may be weakened by stress as 20% of cases had a preceding traumatic event. Real-time ultrasonography e stablishes the diagnosis, demonstrating the anterolateral displacement of the sternocleidomastoid muscle by a thickened omohyoid muscle during swallowing. Surgical transection can achieve cure, but due to limited studies available, they should be reserved for patients who are extremely bothered. Intramuscular injection of botulinum toxin is an effective alternative, but recurrence is expected. PMID:33626894 | DOI:10.1177/0003489421995037 View on the web Inoreader.

Combined treatment of ureteropelvic junction obstruction and renal calculi with Robot Assisted Laparoscopic Pyeloplasty and Laser Lithotripsy in children: case report and non systematic review of the literature

xlomafota13 shared this article with you from Inoreader Combined treatment of ureteropelvic junction obstruction and renal calculi with Robot Assisted Laparoscopic Pyeloplasty and Laser Lithotripsy in children: case report and non systematic review of the literature Via The International Journal of Medical Robotics and Computer Assisted Surgery Summary: Objective(s) The incidence of urinary tract stone disease is steadily increasing in both adult and paediatric populations. This condition develops due to different factors: dietary or metabolic alterations, infection and congenital anatomic malformations. Standard indications and treatments for children are analogous to the ones indicated for adults. Extracorporeal shock wave lithotripsy (SWL), ureterorenoscopy (URS), percutaneous nephrolithotomy (PCNL) should be preferred to more invasive techniques. Moreover, the introduction of laparoscopic and robot assisted laparoscopic approaches have improved surgical outcomes, lowering the bleeding risk with higher stone‐free rates, even in complicated cases. Despite these well‐known improvements, there are few reports regarding laparoscopic robot assisted management for urinary tract stone disease in paediatric patients under the age of ten, especially with concomitant treatment of ureteropelvic junction obstruction and multiple calyceal stones. Patient and Method(s) A four years old child was referred for recurrent right abdominal flank pain, macroscopic haematuria and a previous history of urinary tract infections. A computed tomography of the abdomen showed right ureteropelvic junction obstruction associated with multiple unilateral stones located in the renal pelvis and in the interpolar renal calyces. Due to its complexity, we held a multidisciplinary meeting with paediatric surgeons and nephrologists to determine optimal treatment. As a result, a combined robot assisted laparoscopic pyeloplasty and renal calculi holmium laser lithotripsy using a digital flexible ureteroscope through an abdominal robotic trocar was performed. No post‐surgical complications were recorded and the patient was discharged within 48 hours following surgery. At subsequent regular follow‐up examinations over a period of 24 months, no signs of recurrence were detected for both ureteropelvic junction obstruction and stone disease. Result(s) Robot Assisted Laparoscopic Pyeloplasty with concomitant laser lithotripsy is a reasonable treatment option for designated young paediatric patients with challenging ureteropelvic junction obstruction complicated by urolithiasis, especially in cases where stones are not amenable with standard procedures.
