Joel M Mor, Yongwei Guo, Konrad R Koch, Ludwig M Heindl
Today's gold standard in the treatment of infrasaccal primary acquired nasolacrimal duct obstruction (PANDO) is external dacryocystorhinostomy (DCR), a relatively invasive procedure that can be performed after failure of recanalizing treatments. However, with progress in the field of diode laser technology, new approaches have emerged. Laser-assisted transcanalicular DCR with subsequent bicanalicular silicon intubation is a new option showing great promise as a viable minimally invasive procedure. Under permanent endoscopic visual control from the nasal cavity, a diode laser fiber is inserted into the lacrimal sac and laser energy is applied to create a bony ostium between the lacrimal sac and the nasal cavity...

Objective: Juvenile on-set recurrent respiratory papillomatosis (JORRP) can be an aggressive and potentially life-threatening disease. To emphasize the importance of complication prevention in local excision surgery, the single-center experience of RRP treatment in a group of patients with relatively short recurrence-free-interval (>4 times/yrs) was reported. Methods: Data of 49 patients underwent papilloma resection during 2002-2013 were retrospectively analyzed. Combined techniques of laser microsurgery and microdebriders were used to remove papillomas, prevent the formation of scar tissue and improve respiratory distress...

Keloid scars are common and have a predilection for young, ethnic skin often with a family history. Keloids can be painful and pruritic and cause significant emotional distress when particularly visible or prominent. In this article, we review the evidence underlying the use of laser- and energy-based devices for treatment of keloid scars, either as monotherapy or in conjunction with other therapies such as corticosteroids, surgery and silicone gel in the treatment of keloid scars.

Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predominantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase 'paradigm shift' in his groundbreaking book The Structure of Scientific Revolutions...

We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus...

We propose and demonstrate a broadly wavelength-tunable mode-locked Ho(3+)/Pr(3+)-codoped ZBLAN fiber laser operating in the 3 μm mid-infrared spectral region based on a semiconductor saturable absorber mirror. Wavelength selection is realized by rotating a plane ruled grating. The fiber laser exhibits stable continuous-wave mode-locking operation over a wide wavelength tuning range of 34 nm (2842.2 nm~2876.2 nm), with a 10.17 MHz repetition rate and 22 ps pulse duration. Stable mode-locked pulses can be maintained until the launched pump power of 1...

Pre-operative evaluation of biliary strictures remains challenging. The dilemma that exists is how to balance the risk of failing to detect malignancy and the potential morbidity caused by unnecessary surgery in patients with benign etiologies. With emerging novel diagnostic modalities, this study aims to assess the efficacy of diagnostic techniques and facilitate a clinical approach to indeterminate biliary strictures. Areas covered: Conventional imaging modalities are crucial in identifying the location of a stricture and are helpful for choosing further diagnostic modalities...

Early debridement and/or eschar removal is regarded as a significant step in the treatment of deep partial and full thickness burns. It aims to control wound bioburden and allows early wound closure by conservative treatment or skin grafting. Preservation of viable dermis accompanied by early wound closure, is regarded as a necessary step to reduce scar related complication, e.g. functional limitations and/or unaesthetic scar formation. Aside from the classical techniques of surgical excision as tangential excision for eschar removal, hydro-surgery, maggot therapy, laser, enzymatic debridement have been described as additional techniques in the burn surgeon's armamentarium...

Resting-state functional magnetic resonance imaging (rsfMRI) is emerging as a useful tool in the multimodal assessment of patients with epilepsy. In pediatric patients who cannot perform task-based fMRI, rsfMRI may present an adjunct and alternative. Although changes in brain activation during task-based fMRI have been described after surgery for epilepsy, there is limited data on the role of postoperative rsfMRI. In this short review, we discuss the role of postoperative rsfMRI after laser ablation of seizure foci...

OBJECTIVE Seizure onset within the insula is increasingly recognized as a cause of intractable epilepsy. Surgery within the insula is difficult, with considerable risks, given the rich vascular supply and location near critical cortex. MRI-guided laser interstitial thermal therapy (LiTT) provides an attractive treatment option for insular epilepsy, allowing direct ablation of abnormal tissue while sparing nearby normal cortex. Herein, the authors describe their experience using this technique in a large cohort of children undergoing treatment of intractable localization-related epilepsy of insular onset...

AIM: Iatrogenic premature rupture of membrane (PROM) is one of the major complications related to fetoscopic laser photocoagulation (FLP) for twin-twin transfusion syndrome (TTTS). However, amniotic fluid leakage (AFL) sometimes spontaneously disappears. This study evaluated the incidence and clinical characteristics of transient AFL after FLP. METHODS: We retrospectively reviewed pregnancies that underwent FLP for TTTS at a single center. Patients with apparent AFL within 2 weeks after FLP were divided into two groups: transient AFL, defined by the disappearance of fluid leakage within a week; and PROM, if AFL persisted continuously for more than a week or premature birth occurred, including miscarriage, within a week of the first symptom of AFL...

Myocardial revascularization surgery (CABG) is the most appropriate treatment for coronary artery disease. Currently, the great challenge is to reduce postoperative complications, such as wound infections, dehiscence, pain, and patients' quality of life. The saphenectomy is the target of complications in 10% of cases, which can cause greater morbidity, time, and cost of hospitalization. Studies show that low-intensity laser or light-emitted diode (LED) therapy promotes positive biomodulation of the tissue repair process, culminating in a lower incidence of dehiscence, pain reduction, and improvement in quality of life...

Introduction.Vibrio species are curved, motile Gram-negative bacilli found in estuarine and marine environments, and are known to cause to gastroenteritis, skin and soft tissue infections, and septicaemia. While not responsible for cholera epidemics, non-O1/O139 Vibrio cholerae (NOVC) is increasingly reported as a cause of gastroenteritis. Case presentation. A 66-year-old man presented to an emergency department with a 1 week history of epigastric pain, emesis and fever. Blood cultures drawn on admission initially demonstrated Gram-negative bacilli, and ultimately grew NOVC, which was later confirmed by matrix-assisted laser desorption ionization-time of flight MS...

Medically intractable epilepsy is associated with increased morbidity and mortality. For those with focal epilepsy and correlated electrophysiological or radiographic features, open surgical resection can achieve high rates of seizure control, but can be associated with neurologic deficits and cognitive effects. Recent innovations have allowed for more minimally invasive methods of surgical seizure control such as magnetic resonance-guided laser interstitial therapy (MRgLITT). MRgLITT achieves the goal of ablating seizure foci while preserving neuropsycho-logical function and offering real-time feedback and monitoring of tissue ablation...
