Hereditary hemorrhagic telangiectasia (HHT) is a mutilating disease associated with the majority of patients with recurrent epistaxis episodes. The aim of this study was to present a single institution experience with patients treated for nasal epistaxis using a combination of Nd:YAG laser and argon plasma coagulation (APC) vs Nd:YAG laser alone, with a minimum follow-up of 3 years. 45 patients (21 men, 24 women) aged from 15 to 84 years with the diagnosis of HHT were treated in the Department of Otolaryngology, Head and Neck Surgery in Homburg/Saar between 10/2002 and 10/2012 because of epistaxis, using a combination of Nd:YAG laser and APC or Nd:YAG laser alone. The observation period ranged from 36 to 120 months. 15 patients were treated with Nd:YAG laser alone and 30 patients with combined Nd:YAG laser and APC. A revision was necessary in three patients (20%) in the Nd:YAG laser group and in nine (33.3%) patients in the combined group. The difference between revision rates after the two therapy forms was not statistically significant (p = 0.492). Bipolar coagulation was additionally applied in 33 patients. There was no statistically significant difference (p = 1.00) in revision rates between patients who were additionally treated with bipolar coagulation and those who did not receive bipolar coagulation as part of their treatment. No case of postoperative septal perforation was observed. Nd:YAG laser therapy remains an established option for treating treat epistaxis in HHT patients.

Treatment of onychomycosis includes topical and systemic agents. However, prolonged use of oral treatment could cause adverse effects and topical antifungal agents have limited penetration. To compare the clinical efficacy and the safety of fractional CO laser combined with topical tioconazole nail solution versus Q-switched 1064 Nd: YAG laser in the treatment of fingernail onychomycosis.

Article Synopsis
- Melasma is a common, chronic skin condition that mainly affects women, presenting as dark patches on the face and is often perceived as a serious cosmetic issue.
- A survey conducted among 199 dermatologists in Turkiye revealed that the majority of patients with melasma are females between the ages of 30 to 40, with mixed melasma being the most common type.
- The study found that topical treatments, particularly Kligman's formula, are most frequently used, while oral treatments like tranexamic acid are less common, and there's a significant recurrence rate of 41%-60%, suggesting the need for better management strategies.
Anion photoelectron spectroscopy and chemical bonding of ThS2- and ThSO.
J Chem Phys

Department of Chemistry, Johns Hopkins University, Baltimore, Maryland 21218, USA.
Anion photoelectron spectra of ThSO- and ThS2- were recorded using the third (355 nm) harmonic of an Nd-YAG laser; these provided the measured vertical detachment energies of each anion. The experiments are supported by extensive coupled cluster calculations on ThSO, ThSO-, ThS2, and ThS2-, as well as the oxygen congeners ThO2 and ThO2-. The ab initio calculations, which included complete basis set extrapolations, spin-orbit effects using four-component coupled cluster, and higher-order correlation contributions through CCSDT(Q), yielded an adiabatic electron affinity for ThO2 that was within 0.

Plasma focus devices represent a class of hot and dense plasma sources that serve a dual role in fundamental plasma research and practical applications. These devices allow the observation of various phenomena, including the z-pinch effect, nuclear fusion reactions, plasma filaments, bursts, shocks, jets, X-rays, neutron pulses, ions, and electron beams. In recent years, considerable efforts have been directed toward miniaturizing plasma focus devices, driven by the pursuit of both basic studies and technological advancements.

Article Synopsis
- The study looked at the risks of retinal detachment (RD) after a specific eye surgery called Boston Type 1 Keratoprosthesis (B1KPro) during the first year and beyond.
- They found that 29% of patients experienced RD, with most cases happening within the first year (21%) and fewer later (7%).
- Important risk factors for early RD included low eye pressure (hypotony), previous eye surgeries, and certain eye conditions, while changes in the retina before surgery were linked to later RD.
