Although often uncomplicated, the current technique for laser suture lysis after filtration surgery requires patient cooperation and appropriate care taken by the surgeon. In cases with suboptimal cooperation, steadying the 50-µm laser aiming beam exactly over a thin 10-0 nylon suture, can be exhausting, difficult for both the patient and the surgeon; it may prove to be ineffective or even precipitate complications. We describe a novel method for laser suture lysis using a multispot laser system, which requires less patient cooperation and surgeon skills and yields excellent results...

The laser speckle contrast imaging (LSCI) is proved to be a reliable tool in flap monitoring in general surgery; however, it has not been evaluated in oral surgery yet. We applied the LSCI to compare the effect of a xenogeneic collagen matrix (Geistlich Mucograft®) to connective tissue grafts (CTG) on the microcirculation of the modified coronally advanced tunnel technique (MCAT) for gingival recession coverage. Gingival microcirculation and wound fluid were measured before and after surgery for six months at twenty-seven treated teeth...

BACKGROUND: A dacryocystorhinostomy (DCR) procedure aims to restore drainage of tears by bypassing a blockage in the nasolacrimal duct, through the creation of a bony ostium that allows communication between the lacrimal sac and the nasal cavity. It can be performed using endonasal or external approaches. The comparative success rates of these two approaches have not yet been established and this review aims to evaluate the relevant up-to-date research. OBJECTIVES: The primary aim of this review is to compare the success rates of endonasal DCR with that of external DCR...

REVIEW

BACKGROUND: Glaucoma is the international leading cause of irreversible blindness. Intraocular pressure (IOP) is the only currently known modifiable risk factor; it can be reduced by medications, incisional surgery, or laser trabeculoplasty (LTP). LTP reduces IOP by 25% to 30% from baseline, but early acute IOP elevation after LTP is a common adverse effect. Most of these IOP elevations are transient, but temporarily elevated IOP may cause further optic nerve damage, worsening of glaucoma requiring additional therapy, and permanent vision loss...

INTRODUCTION: Lymphatic malformations are benign anomalies derived from the abnormal development of lymphatic channels. Usually asymptomatic, they can cause compression on adjacent structures or present acute complications (bleeding or infection). Small asymptomatic lesions can be conservatively managed since the possibility of spontaneous regressions is described, while symptomatic lesions require active management. Less invasive therapeutic options are now preferred instead of surgery (sclerotherapy, laser therapy)...

Stone disease has afflicted mankind since centuries; records from ancient civilisations of India and Egypt have shown stones in human bodies. The scientific mind of humans has always made smart endeavours to remove the kidney stones. From large instruments made like the beaks of different animals and birds in 600 BC (Indian civilisation) to extremely sophisticated and miniaturised endoscopic intruments of today the human race has travelled a long way. The theme has always been to remove the stones with minimal morbidity and mortality and with minimum pain to the patient...

Flexible ureteroscopy is a highly resolving surgery which is able to solve most renal lithiasis of any Urology Department, with very low economic impact. It is a technique that has helped to continue treatment when SWL couldn't, and also has reduced the number of percutaneous renal surgeries that we currently perform. In this paper, we try review three important features of the operation: Technique, minimal requirements that we need to perform this surgery in a Urology Department, and the different possibilities to treat the lithiasis with holmium laser...

Gynecologist and plastic surgeons pioneered the application of lasers in medicine and surgery almost 5 decades ago, initially used to treat cervical and vaginal pathologies. Ever since, energy-based devices have been deployed to treat pelvic pathologies and improve fertility. Recent technological developments triggered an unprecedented wave of publications, assessing the efficacy of fractional laser, and radiofrequency on the vaginal wall in reversing natural aging processes. Studies have shown that a certain degree of thermal energy deposited on the vaginal wall stimulates proliferation of the glycogen-enriched epithelium, neovascularization, and collagen formation in the lamina propria, and improves natural lubrication and control of urination...

Glaucoma is a serious chronic ophthalmic disease since it causes irreversible visual disability if untreated can lead to blindness. Treatment options include medications (classified into five major classes of drugs which are muscarinic cholinergic agonists, alpha-2 adrenergic agonists, beta-1 adrenergic antagonists, prostaglandins [PGs], and carbonic anhydrase inhibitors); use of laser therapy or conventional surgery. Pharmacoeconomic analysis helps in choosing among this variety of treatments. There is a great need for such analysis in Egypt since undergoing of it in different countries or societies may produce different results...

AIM: Transurethral resection of prostate (TURP) is considered a gold standard surgical procedure. The management of benign prostatic hyperplasia (BPH) has undergone tremendous change in recent years and shifted from open to minimal invasive procedure. With the advancement in technology and skills of surgeons, lasers have been used more liberally, particularly holmium laser. Holmium laser enucleation of prostate (HoLEP) is seen as close rival of TURP. The objective if this study is to observe long- and short-term outcomes of transurethral resection and holmium laser enucleation in the prostate of more than 60 g...

The current study reports comparing the postoperative mechanical properties of the anterior capsule between femtosecond laser capsulotomy (FLC) and continuous curvilinear capsulorhexis (CCC) of variable size and shape in porcine eyes. All CCCs were created using capsule forceps. Irregular or eccentric CCCs were also created to simulate real cataract surgery. For FLC, capsulotomies 5.3 mm in diameter were created using the LenSx® (Alcon) platform. Fresh porcine eyes were used in all experiments. The edges of the capsule openings were pulled at a constant speed using two L-shaped jigs...

RNA-guided genome surgery using CRISPR-Cas9 nucleases has shown promise for the treatment of diverse genetic diseases. Yet, the potential of such nucleases for therapeutic applications in nongenetic diseases is largely unexplored. Here, we focus on age-related macular degeneration (AMD), a leading cause of blindness in adults, which is associated with retinal overexpression of, rather than mutations in, the VEGFA gene. Subretinal injection of preassembled, Vegfa gene-specific Cas9 ribonucleoproteins (RNPs) into the adult mouse eye gave rise to mutagenesis at the target site in the retinal pigment epithelium...

BACKGROUND: Endothelial cells derived from human induced pluripotent stem cells (iPSC-ECs) promote angiogenesis, and more recently induced endothelial cells (iECs) have been generated via fibroblast trans-differentiation. These cell types have potential as treatments for peripheral arterial disease (PAD). However, it is unknown whether different reprogramming methods produce cells that are equivalent in terms of their pro-angiogenic capabilities. OBJECTIVES: We aimed to directly compare iPSC-ECs and iECs in an animal model of PAD, in order to identify which cell type, if any, displays superior therapeutic potential...

INTRODUCTION: Posterior Capsular Opacifications (PCO) is a frequent complication of cataract surgery following posterior chamber intraocular lens implantation. Nd -Yag laser capsulotomy is the treatment of choice for PCO and is known to be associated with complications like Raised Intraocular Pressure (IOP), Intraocular lens pitting, intraocular lens cracks, cystoid macular oedema, retinal detachment, corneal burns. Raised IOP is the most common complication and prescribing anti-glaucoma drugs post capsulotomy is a common practise...

Importance: There are few reports evaluating awake, office-based carbon dioxide (CO2) laser surgery for laryngeal lesions. To date, this study was the largest reported case series of office-based laryngeal surgery by fiber delivery CO2 laser. Office-based laryngeal surgical procedures have become increasingly popular. Technical problems and treatment outcomes associated with the use of a CO2 laser for office-based laryngeal surgery have yet to be fully addressed. Objectives: To discuss a single institution's clinical experience with office-based CO2 laser laryngeal surgery and the feasibility and limitations associated with this procedure...

OBJECTIVES: As a treatment for partial deafness with residual hearing in the lower frequency range, the combined acoustic and electric stimulation of the cochlea has become widespread. Acoustic stimulation is provided by a hearing aid's airborne sound and the electric stimulation by a cochlear implant electrode array, which may be inserted through the round window or a cochleostomy. To take advantage of that concept, it is essential to preserve residual hearing after surgery. Therefore, the intracochlear electrode array should not compromise the middle ear vibration transmission...

BACKGROUND: Reconstructive procedures with pedicled and free flaps are associated with a risk of ischemia. Prostaglandin E1 (PGE1) is a hormone-like substance with known antiischemic and tissue-protective effects. The aim of this study was to evaluate the effect of PGE1 on the microcirculation in random pattern skin flaps on rats. METHODS: Twenty-four rats were divided into 2 groups: an intervention group given PGE1 for 6 hours and a control group given saline. The flap (2 × 10 cm) was created on the back of the rats, and the microcirculation was monitored with laser Doppler perfusion imaging in 5 different zones (1, proximal; 5, distal) before surgery and after 60, 180, and 360 minutes postoperatively...
