BACKGROUND: Varices and venous insufficiency are common and serious health problems in the general population which affect quality of life. Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux, and the endovenous laser ablation (EVLA) method has been widely accepted all over the world. In this method, ablation is provided by a laser fiber inserted into the lumen of the vein. Initially, the fibers were 810 nm, but today the fibers are usually 940, 980, or 1470 nm...

Kallidinogenase has been used to treat retinal vein occlusion (RVO) in patients, although there are no evidences on the effects of kallidinogenase on the retinal edema and the non-perfused areas in eyes with a RVO. We have established a murine RVO model with retinal edema and non-perfused areas. The purpose of this study was to evaluate the effects of kallidinogenase on the retinal edema and size of the non-perfused areas in the mouse RVO model. We evaluated the thickness of the retinal layers and size of the non-perfused areas, and the blood flow by laser speckle flowgraphy in RVO model...

A 40-year-old woman with a history of alopecia areata related to stress or hormonal changes was treated for bilateral primary symptomatic varicose veins (CEAP clinical score C2S) of pelvic origin, using a staged procedure. Her first procedure entailed pelvic vein embolisation of three pelvic veins using 14 coils and including foam sclerotherapy of the tributaries, using 3% sodium tetradecyl sulphate. Following this procedure, she had an exacerbation of alopecia areata with some moderate shedding of hair. Subsequently, she underwent endovenous laser ablation under local anaesthetic without incident...

Translocation renal cell carcinoma (RCC) is a rare aggressive malignancy in adults. A 40-year-old man presented with painless macroscopic haematuria. Initial investigations of renal ultrasound, CT scan, urine culture and urine cytology were normal. On rigid cystoscopy and pyelo-ureteroscopy, bleeding was seen from a normal-appearing right renal upper pole. An arteriovenous malformation was suspected, and laser cautery was performed. Left renal biopsy was performed due to proteinuria and suggested IgA nephropathy...

Ultrasound‑targeted microbubble destruction (UTMD) can promote the entry of plasmid DNA (pDNA) into the cell cytoplasm, by increasing the permeability of the cell membrane. But the transfection efficiency remains low due to inability of the pDNA to enter the nucleus. Various methods have been explored to improve the UTMD transfection efficiency, but with little success. In cells, the classic nuclear localization signal (cNLS) peptide is an amino acid sequence that signals proteins that are due for nuclear transport...

PURPOSE: We previously showed that intravitreal injection of the sFLT morpholino-oligomer (FLT-MO) suppresses laser-induced choroidal neovascularization (CNV) in mice by decreasing the membrane bound form of Flt-1 while increasing the soluble form of Flt-1 via alternative splicing shift. In this study, we examined whether cyclic RGD peptide (cRGD) can promote morpholino-oligomer accumulation in CNV following tail vein injection, and whether systemic cRGD conjugated FLT-MO (cRGD-FLT-MO) suppresses CNV growth...

REVIEW
Paula Scholz, Lebriz Altay, Sascha Fauser
Micropulse laser treatment is an alternative to the conventional continuous-wave laser for the treatment of retinal or macular diseases. In contrast to the conventional laser, the therapeutic effect of the subthreshold micropulse laser is not accompanied by thermal retinal damage. This fact is of particular importance when a treatment near the fovea is required. Micropulse treatment is applied in indications such as central serous chorioretinopathy (CSC), diabetic macular edema (DME), or macular edema due to retinal vein occlusion (RVO)...
