Objectives Transforming growth factor-beta1 (TGF-β1) may participate in local chronic inflammatory processes in varicose veins and in venous wall structure modifications through regulation of matrix metalloproteinases (MMP) and their inhibitors (tissue inhibitor of metalloproteinase (TIMP)). The aim of this study was to analyze the effect of TGF-β1 in the vein wall, namely on the gene expression of selected MMP, TIMP and TGF-β1 receptors. Methods Healthy vein samples were harvested from eight subjects who underwent coronary bypass graft surgery with great saphenous vein. Each vein sample was divided into two segments, which were cultivated separately in vitro (one of the segments had TGF-β1 added) and then submitted to gene expression analysis. Results In the TGF-β1 supplemented group, there was a general increase in the mean gene expression. Specifically, expression of MMP9, MMP12, TIMP1 and TIMP2 were statistically significant. Conclusion The results of this study demonstrate that the gene expression of MMP9, MMP12, TIMP1 and TIMP2 was influenced by the addition of TGF-β1. These results may be translated to chronic venous insufficiency framework and suggest involvement of TGF-β1 in the vein wall pathology.
Purpose
To report a case of bilateral papilledema and abducens nerve palsy following cerebral venous sinus thrombosis in a 9-year-old female with undiagnosed Gradenigo's Syndrome.
Observations
The patient presented to our Emergency Room with a unilateral left 6th nerve palsy, left eye relative afferent pupillary defect, and bilateral papilledema. She underwent cranial magnetic resonance imaging with gadolinium contrast and magnetic resonance venography, which diagnosed a left mastoiditis, left sigmoid sinus and jugular vein thrombosis. The patient underwent urgent mastoidectomy and myringotomy with tube placement and was admitted for adequate treatment with intravenous antibiotics and anticoagulants.
Conclusions and importance
Gradenigo's syndrome is a rare complication of otitis media, and even rarer is cerebral venous thrombosis. This potentially life-threatening situation requires immediate surgical and antibiotic therapy. Ocular symptoms can be the initial signs of this illness.
Purpose
To evaluate the effect of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy on intraocular lens (IOL) position and anterior segment parameters with a new swept-source anterior segment optical coherence tomography (AS-OCT) device (Anterion
®
, Heidelberg Engineering GmbH).
Patients and Methods
A total of 50 eyes from 50 consecutive patients were included. All patients had visually significant posterior capsular opacification (PCO) after uneventful phacoemulsification surgery with manual capsulorhexis and single-piece C-loop acrylic IOL implantation (AcrySof
®
SA60AT) and were treated with Nd:YAG laser. Anterior segment images were captured with Anterion
®
in non-dilated conditions before and one month after the procedure. In the “Metrics App”, we collected data of the anterior chamber angle (ACA) 3 and 9 o’clock, the anterior chamber depth (ACD), the anterior chamber volume (ACV), and the central corneal thickness (CCT). We also collected demographic and clinical data [age, gender, months from surgery to Nd: YAG capsulotomy, pre- and post-capsulotomy corrected distance visual acuity (CDVA) and spherical equivalent, and axial length].
Results
We did not find a statistically significant difference in ACD after the Nd:YAG capsulotomy (3.96 ± 0.55 vs 3.97 ± 0.55 mm, p = 0.10). In 28 patients, we noted a backward movement of the IOL; in the remaining 22, the IOL moved forward or did not change at all. We did not observe significant changes in ACA at the 3 and 9 o’clock reference points, ACV, or CCT. There was an improvement in CDVA after the procedure (0.37 ± 0.21 vs 0.12 ± 0.27 logMAR, p = 0.015), without statistically significant differences in SE (−0.15 ± 0.84 vs −0.25 ± 0,93, p = 0.42). Axial length was not correlated with ACD variations after the procedure (p = 0.67).
Conclusion
Our results show that Nd:YAG laser capsulotomy does not change the axial position of a single-piece C-loop acrylic IOL inside the capsular bag, as well as other anterior chamber parameters.
Antiphospholipid syndrome is an acquired autoimmune disease characterized by
hypercoagulability associated with recurrent venous and arterial thromboembolism
in the presence of antiphospholipid antibodies. Herein, we report a case of
rapid sequential retinal vein and artery occlusion as the first manifestation of
a primary antiphospholipid syndrome triggered by an acute
Mycoplasma
infection in a previously healthy 11-year-old
patient. On day 1, ophthalmoscopy revealed a central retinal vein occlusion. The
patient developed temporal branch retinal artery occlusion the next day. On day
3, a central retinal artery occlusion was observed. Serum lupus anticoagulant,
immunoglobulin (Ig) G anticardiolipin, IgG anti-β2-glycoprotein 1
antibody, and
Mycoplasma pneumoniae
IgM antibody levels were
increased. Thus, retinal vascular occlusions can be the first manifestation of
primary antiphospholipid syndrome. Although it may not improve visual prognosis,
prompt diagnosis and treatment are essential to avoid further significant
morbidity.
