Resolving Myopic Foveoretinal Detachment by Fovea-Saving Internal Limiting Membrane Peeling: A Case-Series Report

Open Journal of Ophthalmology 2023年第1期13卷 106-121页

Background: In highly myopic eyes, myopic foveoschisis (MF), the earliest stage of myopic traction maculopathy (MTM), is present in up to 34% of patients with pathologic myopia and slowly progresses to form foveoretinal detachment (FRD) or macular hole (MH) with or without macular hole retinal detachment (MHRD) as a part of its natural history. Aim: To describe the microstructural and functional results in three highly myopic eyes that underwent macular surgery for early-stage MTM. The last postoperative structural findings were correlated with the final vision and macular automated microperimetry evaluation. Methods: We retrospectively reviewed three highly myopic eyes that underwent successful fovea-saving internal limiting membrane (FS-ILM) macular surgery for chronic FRD at Oftalmologia Integral ABC, Mexico City, Mexico. We performed postoperative multimodal microstructural and functional evaluations, including SD-OCT, SS-OCT, and microperimetric macular examinations. Results: There was a substantial difference between best-corrected visual acuity (BCVA) preoperatively and postoperatively in all three cases. Postoperative surgery was associated with significant improvement in visual acuity confirmed using a paired-sample permutation test. The mean presurgical BCVA value (LogMAR;mean ± SE) was ~0.83 ± 0.15, and the postsurgical value was ~0.43 ± 0.52 (P = 0.00065). The myopic foveoretinal detachment evaluation was ~7.3 ± 3.5 months, with a mean postoperative follow-up time of ~14 ± 4.08 months. Furthermore, postoperative multimodal imaging tests demonstrated an abnormal microstructural foveal SS-OCT pattern without evidence of macular hole (MH) development at the postoperative follow-up. Macular microperimetry confirmed a subclinical reduced macula threshold sensitivity with an anomalous retinal sensitivity analysis map and a stable central foveal fixation site. Conclusions: Even with the successful microstructural disappearance of myopic macular detachment, the

A Comparative Study of Non-Volatile Compounds Present in 3R4F Cigarettes and iQOS Heatsticks Utilizing GC-MS

引用

American Journal of Analytical Chemistry 2019年第3期10卷 76-85页

作者： miguel Penin Ibanez Daniel Martin Alicia gonzalez Gonzalvez Helmut H.Telle angel gonzalez Urena Departamento de Quimica Fisica Aplicada Facultad de CienciasUniversidad Autonoma de MadridMadridSpain

It is now widely suggested that people who are dependent on nicotine should switch from ordinary tobacco smoking to alternative products, which at least reduce the overall harm from smoking. A number of alternatives are now popular, including electronic cigarettes and heatsticks. In this work comparative analysis of the smoke/aerosol emission from 3R4F standard cigarettes and iQOS heatsticks was undertaken. For this, gas chromatography-mass spectrometry (GC-MS) analysis was applied, to measure the non-volatile compounds of smoke/aerosol emission from individual samples, with the specific aim to determine their content of nicotine and selected other main components. All measurement data were collected under the Health Canada Intense (HCI) puffing regime. The most relevant findings of the present investigation can be summarized as follows. First, the number of measured aerosol components in the iQOS samples, with respect to those of 3R4F samples, was significantly lower (notably 37 versus 12 components). Second, the analysis of the iQOS and 3R4F GC-MS chromatographic fingerprints indicated a non-nicotine global component reduction (number and areas excluding nicotine) of larger than 80% for the iQOS samples in comparison to 3R4F samples. Third, the nicotine content of the iQOS aerosol was less than half that contained in the 3R4F smoke. The results from the present investigation indicate that—except for nicotine—smokers are exposed to a largely reduced number and amount of non-volatile, non-nicotine components in the iQOS heatstick aerosol, in comparison to those in the 3R4F cigarette smoke.
