In 1991 and 1992, we presented a review of our experience using Nd:YAG laser fiber and bipolar needles to coagulate uterine myomas laparoscopically. We now present a comparison study of the Nd:YAG laser vs. bipolar coagulation needles for laparoscopic reduction of symptomatic uterine myomas. Since October 1990, we have performed over 300 cases of laparoscopic coagulation of symptomatic uterine myomas. The technique includes reduction of uterine and myomata size using depot leuprolide for a three to four month period of time. Hysteroscopic examination and endometrial sampling is performed during this preoperative period. The Nd:YAG laser fiber is a 600 micron bare fiber combined with a 50 watt Nd:YAG laser. The bi-polar needle is made in 30 and 45 mm lengths. The needles measure 5 cm in length and are inserted through a 5.5-mm trocar. Coagulation effect is measured by a standard ammeter. Myoma shrinkage is measured by pre- and post-operative vaginal ultrasound examination. Results reveal additional shrinkage 50-70% beyond the leuprolide effect. No myoma regrowth has been noted in this 3 year period. Minimal follow-up was 12 months. For patients with significant uterine bleeding, endometrial ablation is carried out at the same time.

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
October 2024
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.
