The causes of floaters include posterior vitreous detachment and fundus hemorrhage, both of which are risk factors for retinal tears. We observed the vitreous of patients with floaters using swept source optical coherence tomography.

Fundus examination was performed, and the vitreous was observed using swept source optical coherence tomography in 202 eyes of 202 patients with floaters. Patients with uveitis, diabetic retinopathy, and other fundus diseases were excluded.

Swept source optical coherence tomography revealed posterior vitreous detachment in 145 of 202 eyes (71.8%) and dot reflex like stardust in the vitreous in 42 of 202 eyes (20.8%). Posterior vitreous detachment occurred in 35 of 42 eyes (83.3%) and 110 of 160 eyes (68.8%) in the stardust (+) and stardust (-) groups, respectively; a significant difference was observed (P <0.001). In the stardust (+) group, 11 of 42 eyes (26.2%) had retinal tears with posterior vitreous detachment and 21 of 42 eyes (50.0%) had fundus hemorrhage. Three of 160 eyes (1.9%) and 4 of 160 eyes (2.5%) in the stardust (-) group had retinal tears with posterior vitreous detachment and fundus hemorrhage, respectively. Both tears and fundus hemorrhage were more frequent in the stardust (+) group than in the stardust (-) group (P <0.001).

The stardust sign on swept source optical coherence tomography indicates the risk of retinal tear.

To report the long-term outcomes of lens capsular flap transplantation (LCFT) as initial treatment for large macular holes (MHs).

Thirteen consecutive eyes with large MHs who received LCFT as primary treatment were reviewed retrospectively. All enrolled eyes underwent standard 23-gauge vitrectomy, internal limiting membrane peeling, LCFT, and 15% perfluoropropane tamponade. Autologous whole blood was applied in selected eyes to make the LCT intact. A face-down position maintained for 2 weeks postoperatively. Data including demographic information, medical history, anatomical and functional outcomes, and complications were recorded.

The mean preoperative MHs diameter was 979.42 ± 388.28 µm. Eight eyes received autologous LCFT, and the other five eyes received allogenic LCFT. Whole blood was applied in seven eyes. The mean follow-up duration was 19.57 ± 6.24 months (range 12.0-32.2 months). The macular hole was successfully closed in all cases (13/13). The median best-corrected visual acuity improved from 1.76 (interquartile range, 1.23-1.91) logarithm of the minimum angle of resolution (median Snellen acuity 20/1,150) preoperatively to 1.16 ± 0.47 logarithm of the minimum angle of resolution (mean Snellen acuity 20/290) (P < 0.01) at the last visit. No severe complications were noted.

Lens capsular flap transplantation may help to improve the closure rate and visual outcomes in large MHs, which could be an alternative method as primary treatment for large MHs.

Altmetric analysis is a way of assessing the social impact of scientific articles. In this study, we aimed to analyze the 100 most-cited articles on the topic of the retina published in ophthalmology journals in traditional metrics and altmetrics.

The term "retina" was searched in the Web of Science database, and articles published in ophthalmology journals were filtered out. A total of 100 highly cited articles from 2010 to 2020 were evaluated for bibliographic data and altmetrics. First, descriptive statistics and then correlation analysis between traditional bibliographies and altmetrics were performed.

According to the Web of Science search, the number of citations of the articles listed in the top 100 list ranged from 809 to 137. The altmetric scores of the articles listed in the top 100 list ranged from 0 to 1,340. There was no statistically significant correlation between the altmetric scores and the number of citations, but there was a statistically weak correlation between the altmetric scores and the average citations per year, H index, impact factor, and number of years since publication.

Altmetrics is not sufficient to determine the scientific value of articles and can be affected by many factors, unlike traditional bibliometrics. However, being a good communicator in social media can support scientific productivity and create social impact.

Retinal manifestations have been described in COVID-19 patients, but it is unknown whether SARS-CoV-2, the causal agent in COVID-19, can directly infect posterior ocular tissues. Here, we investigate SARS-CoV-2 host factor gene expression levels and their distribution across retinal and choroidal cell types.

Query of single-cell RNA sequencing data from human retina and choroid.

We find no relevant expression of two key genes involved in SARS-CoV-2 entry, ACE2 and TMPRSS2, in retinal cell types. By contrast, scarce expression levels could be detected in choroidal vascular cells.

Given the current understanding of viral host cell entry, these findings suggest a low vulnerability of the posterior eye segment to SARS-CoV-2 with a potential weak spot in the vasculature, which could play a putative causative role in ocular lesions in COVID-19 patients. This may qualify the vasculature of the human posterior eye segment as an in vivo biomarker for life-threatening vascular occlusions in COVID-19 patients.

We present the management of a peripartum pelvic ring disruption. Initial conservative treatment failed; ultimately, open reduction with internal fixation was required. Four years later, the patient gave birth to another child by elective cesarean delivery.

Pelvic ring fracture is a rare occurrence during childbirth. The mechanism involves hormonally mediated ligamentous laxity of the pelvis combined with the forceful movement of the fetal head. This case highlights the continuum of care from injury to treatment, and follow-up, demonstrates proper management of pregnancy-related pelvic ring injury, and explores the role of previous pelvic ring injury in a pregnant patient.

A 23-year-old woman with an Osborne-Cotterill lesion and posterolateral rotatory instability (PLRI) of the elbow was treated with osteochondral allograft transplantation (OCA) and lateral ulnar collateral ligament (LUCL) repair with internal brace. Two years after surgery, she reported resolution of pain and returned to all recreational activities. She reported no mechanical symptoms and no episodes of postoperative instability.

PLRI can present with an Osborne-Cotterill lesion in addition to LUCL injury. The purpose of this case report was to describe the use of OCA to manage bony defects in the capitellum in addition to LUCL repair for patients with PLRI.

An exceptional event occurred during gradual extension with an external fixator for recurrent small finger Dupuytren flexion deformity. A massive proximal interphalangeal joint distraction arose, possibly because of the center of rotation misalignment and a hasty patient-controlled correction. The device was removed, and a plaster splint protected the finger for 5 days to prevent dislocation of the unstable joint. It relocated with an acceptable clinical result.

Gradual extension of Dupuytren contractures with an external fixator may induce severe joint distraction by eccentric placement of the device. On the other hand, the good outcome of this case report may inspire further research on controlled joint distraction in hooked deformity.

Wide surgical excision is the standard treatment for severe hidradenitis suppurativa (HS). Because of the nature of HS, these wounds are often nonsterile, located in moist intertriginous regions, and closed under tension, increasing the risk for surgical site complications. Although uncommon, absorbable sutures may confer benefits over nonabsorbable material for skin closure. Accordingly, the authors evaluated the use of absorbable, braided, transcutaneous polyglactin sutures after wide surgical excision of HS.

The authors performed a retrospective chart review for all consecutive patients who underwent wide surgical excision of HS at a tertiary university hospital between January 2009 and March 2020.

Sixty consecutive patients with 174 operative sites were included in the study. The surgical site complication rate was 17.8%. Postoperative complications included wound dehiscence (n = 18), surgical site infection (n = 2), and scar contracture (n = 1). Sutures were removed from 12 (6.9%) operative sites. Factors influencing complications were Hurley grade and area of excision. Complications did not differ significantly among disease locations (P = .6417).

The results support the growing evidence that absorbable sutures are an appropriate option after wide surgical excision of HS.

To determine if a weight check and heart failure symptom evaluation with each wound care visit could impact wound healing in patients with heart failure and chronic leg wounds.

This was a descriptive, correlational study at an outpatient wound healing center in the Pacific Northwest. see more A convenience sample of individuals currently enrolled at the center with leg wounds and heart failure was identified from standardized electronic medical records. The comparison group received standard care. The intervention group received a body weight check via digital scale and heart failure self-assessment via a standardized assessment tool. Outcome measures included healing rates with weight exacerbation, number of referrals, and hospitalizations for exacerbations.

A total of four participants received the intervention, and three were in the control group. Descriptive analysis showed no significant differences between groups or between weight and left ventricle ejection fraction to wound surface area change. A significant positive correlation was observed between past referrals and past hospitalization (rs = 0.
