Project description:PurposeTo consolidate the existing literature evaluating anterior capsular release and circumferential capsular release in the treatment of adhesive capsulitis (AC) of the shoulder.MethodsThe electronic databases PUBMED, EMBASE, MEDLINE and CENTRAL (Cochrane Central Register of Controlled Trials) were searched from data inception to October 8, 2020. Data are presented descriptively where appropriate. A meta-analysis was conducted for patient-reported outcomes.ResultsOverall, there were forty-six articles included. The majority of patients underwent circumferential release compared to anterior release (80.1% vs. 19.9%). Concomitant Manipulation Under Anesthesia (MUA) was employed in 25 studies, with a higher occurrence in the anterior compared to the circumferential release group (70% vs 60%). Both groups experienced significant improvements postoperatively in range of motion (ROM) and patient-reported outcomes. Complication rates were low for both anterior release (0.67%) and 360° release (0.44%).ConclusionBoth anterior and circumferential release are effective techniques for treating AC with low complication rates. Future studies should improve documentation of patient demographics, surgical techniques and outcomes to determine an individualized treatment protocol for patients.Level of evidenceLevel IV, Systematic Review of Level I-IV studies.

Project description:The present study describes a surgical technique for the management of complex dislocation and subluxation of the intraocular lens (IOL)-capsular bag (CB)-capsular tension ring (CTR) complex. During the procedure, one double-curved suture was inserted through the sclera into the posterior chamber, passing through the anterior capsules and then into the anterior chamber. The suture lines were pulled out from above and below the IOL-CB-CTR complex and a knot was tied 1 mm away from the corneoscleral incision. The IOL-CB-CTR complex was repositioned by adjusting the suture length. This novel method does not require explanting of the original IOL, allowing the IOL-CB-CTR complex to be immobilized in a simple and effective way.

Project description:ObjectiveTo analyse outcomes in different forms of persistent fetal vasculature (PFV).Methods and analysisRetrospective cohort study at a university-based practice of children presenting with PFV between 2011 and 2020. Exclusion criteria was surgical management outside of our institution and follow-up less than 1 month. Wilcoxon and Student's t-tests were used for statistical analysis.ResultsForty-six eyes of 45 patients presented with PFV at 16.7±31.3 (median 2.8) months old with 32.6±29.8 (median 22.5) months of follow-up. Types of PFV included: mild combined anterior-posterior (23 eyes, 50%), severe combined anterior-posterior (18 eyes, 39%), severe anterior (3 eyes, 7%), mild anterior (1 eye, 2%) and posterior (1 eye, 2%). Thirty-two eyes (70%) underwent PFV surgical correction; lensectomy (13 mild combined), vitrectomy (3 mild combined), sequential lensectomy then vitrectomy (3 severe combined), combined lensectomy-vitrectomy (11 severe anterior or severe combined), laser retinopexy (1 mild combined). Five eyes required additional vitrectomy surgery for retinal detachment, fold or cyclitic membrane. Nine eyes developed glaucoma, six requiring Intraocular pressure (IOP)-lowering surgery. At final follow-up, 32 eyes had at least form vision and 6 eyes were aversive to light. Eight eyes, all which were severe combined, and four that did not undergo PFV surgery, were unable to detect light due to phthisis bulbi (7) and optic nerve hypoplasia (1).ConclusionsClassification of PFV is important in determining surgical approach with severe cases often requiring both lensectomy and vitrectomy for optimal anatomic and functional outcomes.

Project description:PurposeTo report the clinical and histopathologic findings associated with congenital fibrovascular pupillary membranes.DesignCase series.ParticipantsSeven infants were included, 6 with a unilateral congenital pupillary membrane and 1 with classic persistent fetal vasculature (PFV).MethodsPatients underwent a membranectomy, pupilloplasty, or lensectomy. Histopathologic examination was performed on the excised membranes.Main outcome measuresVisual acuity and pupil size.ResultsFour of the 6 patients with a unilateral congenital pupillary membrane had 1 or more recurrences after a membranectomy and pupilloplasty. The most recent pupil size ranged from 2 to 5 mm in the affected eye. When last tested, the vision in the affected eye was excellent in 4 of the 6 patients. The 2 patients without recurrences of the pupillary membranes underwent multiple iris sphincterotomies at the time of the initial surgery. Histopathologic examination of 2 primary pupillary membranes showed fibrovascular tissue that did not stain for neuron-specific enolase. Smooth muscle actin was only present in vascular walls. In contrast, histopathology of a recurrent pupillary membrane revealed collagenized fibrovascular tissue that was immunoreactive for smooth muscle actin. Finally, histopathology of the retrolenticular membrane excised from an infant with classic PFV was similar to the latter aside from hypercellularity.ConclusionsCongenital fibrovascular pupillary membranes in infants are likely a variant of PFV that may recur if incompletely excised. The risk of these membranes recurring may be reduced by excising as much as the membrane as possible and enlarging the pupil with iris sphincterotomies. A lensectomy should be avoided if possible.

Project description:Background Asthma and atherosclerotic cardiovascular disease share an underlying inflammatory pathophysiology. We hypothesized that persistent asthma is associated with carotid plaque burden, a strong predictor of atherosclerotic cardiovascular disease events. Methods and Results The MESA (Multi-Ethnic Study of Atherosclerosis) enrolled adults free of known atherosclerotic cardiovascular disease at baseline. Subtype of asthma was determined at examination 1. Persistent asthma was defined as asthma requiring use of controller medications, and intermittent asthma was defined as asthma without controller medications. B-mode carotid ultrasound was performed to detect carotid plaques (total plaque score [TPS], range 0-12). Multivariable regression modeling with robust variances evaluated the association of asthma subtype and carotid plaque burden. The 5029 participants were a mean (SD) age of 61.6 (10.0) years (53% were women, 26% were Black individuals, 23% were Hispanic individuals, and 12% were Chinese individuals). Carotid plaque was present in 50.5% of participants without asthma (TPS, 1.29 [1.80]), 49.5% of participants with intermittent asthma (TPS, 1.25 [1.76]), and 67% of participants with persistent asthma (TPS, 2.08 [2.35]) (P≤0.003). Participants with persistent asthma had higher interleukin-6 (1.89 [1.61] pg/mL) than participants without asthma (1.52 [1.21] pg/mL; P=0.02). In fully adjusted models, persistent asthma was associated with carotid plaque presence (odds ratio, 1.83 [95% confidence interval, 1.21-2.76]; P<0.001) and TPS (β=0.66; P<0.01), without attenuation after adjustment for baseline interleukin-6 (P=0.02) or CRP (C-reactive protein) (P=0.01). Conclusions Participants with persistent asthma had higher carotid plaque burden and higher levels of inflammatory biomarkers, compared with participants without asthma. Adjustment for baseline inflammatory biomarkers did not attenuate the association between carotid plaque and asthma subtype, highlighting the increased atherosclerotic cardiovascular disease risk among those with persistent asthma may be multifactorial.

Project description:Persistent left superior vena cava is the most common congenital anomaly of thoracic venous return, which results when the left anterior cardinal vein fails to regress. A 41-year-old African American male with a history of an unspecified childhood cardiac murmur presented to the emergency department with congestive heart failure exacerbation revealing an incidental finding of a persistent left superior vena cava. Ultimately, he required implantable cardioverter defibrillator placement and cardiac transplantation assessment. In the setting of advanced device placement or cardiac transplantation, a persistent left superior vena cava warrants several important clinical considerations at a center capable of addressing the possibility of a right-sided approach and transplantation irregularities.

Project description:To evaluate the outcome and per- and postoperative complications of the surgical management of patients with a persistent stapedial artery (PSA).A systemic literature search for reports on patients treated for pulsatile tinnitus and/or conductive hearing loss caused by a PSA was conducted of the PubMed and Embase databases using the terms "stapedial" and "artery." Inclusion criteria were adequate description of the intervention and pre- and postoperative signs and symptoms. In addition, one case of a PSA, treated at VU University Medical Center Amsterdam, The Netherlands, was included in this series.Middle ear surgery consisting of stapedotomy or stapedectomy, and/or transection of the PSA.Pre- and postoperative hearing levels, pre- and postoperative pulsatile tinnitus, and per- and postoperative complications.Seventeen patients and 18 operated ears were evaluated (16 patients described in 14 articles and our case). Twelve out of 14 ears in which a stapedotomy or stapedectomy was initiated experienced improvement in hearing. In four cases pulsatile tinnitus was described pre- and postoperatively. In all four, pulsatile tinnitus subsided after transection of the PSA. Peroperative bleeding from the PSA was described in four patients, which could be controlled during the procedure. No significant postoperative sequelae were reported.In case of a PSA, improvement of conductive hearing loss is best achieved by stapes surgery, while pulsatile tinnitus is effectively treated with transection of the PSA. To date no long-term postoperative complications have been reported.

Project description:BackgroundTo report a novel surgical technique for recurrent pupillary optic capture after flanged intraocular lens (IOL) fixation.MethodsIn this retrospective case series, we detail our use of two parallel 7-0 polypropylene sutures passed between the iris plane and the optic of scleral-fixated IOL to address pupillary optic capture. Flanges were created using ophthalmic cautery to secure it to the sclera without suture.ResultsTwo eyes with pupillary optic capture underwent a sutureless surgical technique using 7-0 polypropylene flanges. No recurrences of pupillary optic capture were observed during the 1-year follow-up.ConclusionOur sutureless surgical technique using a 7-0 polypropylene flange was an effective, efficient, and less invasive approach for treating recurrent pupillary optic capture.

Project description:A 16-year-old man had a traumatic accident during motor-cross racing and sustained an anterior hip dislocation with fracture of anterior superior and anterior inferior iliac spines. The hip was emergently reduced and further imaging was obtained to evaluate the lesion and bony fragments. Computed tomography confirmed the presence of two large fragments and a small fragment from the antero-inferior acetabulum. The patient underwent open reduction and internal fixation of the iliac spines and the reparation of anterior hip capsule. No complications occur after 1 year of follow-up. We present the case and a review of the literature for this lesion.
