Endonazal endoscopic dacryocystorhinostomy (DCR) with radiofrequency (RF) surgical technique is a procedure selected for nasolacrimal duct obstruction and chronic dacryostenosis in the setting of patent canaliculi and a functional lacrimal pump. Two major approaches are utilized: external, via a transcutaneous incision and endonasal endoscopically guided. The surgery has the high success rate via both approaches. We review the history, evolution, current techniques, complications and future directions of DCR radiofrequency RF operative technique. The modified endonasal RF-coagulation technique was performed in patients aged 18 - 85 (women-80, men-35) from 2017 to 2023. All patients suffered from chronic dacryocystitis. They had been administered the course of traditional conservative treatment and were provided with the ophthalmologist’s and otorhinolaryngology’s consultations prior to the surgery. In order to verify the diagnosis, the patients were conducted the CT-scan examination of nasal cavity and paranasal sinuses as well as the endoscopy of nasal cavity. Endonasal dacryocystorhinostomy with RF coagulator proved to be effective in 80% of patients;Over 3 - 4 years following the surgery, the recurrence was manifested in 8 patients after 6 months and in 12 patients, after a year. The above mentioned surgical treatment is administered by minimally invasive surgical method. At the same time, the long-term, for about 1 year, implantation of silicone drainage in the nasolacrimal ducts significantly reduces the risk of recurrence. At the present stage, the endoscopic Endo-DCR surgery is being improved, and the diverse treatment methods, including radiofrequency (RF) in endonasal endoscopic microsurgical techniques, are being studied and introduced into practice.

Brillouin microscopy, which maps the elastic modulus from the frequency shift of scattered light, has evolved to a faster speed for the investigation of rapid biomechanical changes. Impulsive stimulated Brillouin scattering (ISBS)spectroscopy has the potential to speed up measurement through the resonant amplification interaction from pulsed excitation and time-domain continuous detection. However, significant progress has not been achieved due to the limitation in signal-to-noise ratio (SNR) and the corresponding need for excessive averaging to maintain high spectral precision. Moreover, the limited spatial resolution also hinders its application in mechanical imaging. Here, by scrutinizing the SNR model, we design a high-speed ISBS microscope through multi-parameter optimization including phase, reference power, and acquisition time. Leveraging this, with the further assistance of the Matrix Pencil method for data processing, three-dimensional mechanical images are mapped under multiple contrast mechanisms for a millimeter-scale polydimethylsiloxane pattern immersed in methanol, enabling the identification of these two transparent materials without any contact or labeling. Our experimental results demonstrate the capability to maintain high spectral precision and resolution at a sub-millisecond integration time for one pixel. With a two-order improvement in the speed and a tenfold improvement in the spatial resolution over the state-of-the-art systems, this method makes it possible for ISBS microscopes to sensitively investigate rapid mechanical changes in time and space.

Absolute erythrocytosis,due to an increased production of red blood cells,becomes manifest with hemoglobin(Hb)levels above 165 or 160 g/L or with a hematocrit(HCT)above 51%and 48%in males and females,respectively.1 A minority of patients have polycythemia vera(PV);acquired secondary erythrocytosis frequently occurs due to appropriate or inappropriate erythropoietin(EPO)excess,while congenital secondary erythrocytosis may derive from genetic defects causing tissue *** erythrocytosis occurs in patients with genetic mutations of the oxygen-sensing pathway(VHL,PHD2,_HIF-1-alpha)or the erythropoietin receptor(EPOR)genes.2 Recently,HFE gene variants have been described in sporadic erythrocytoses.3 In a high proportion(about 70%)of patients with erythrocytosis,a specific etiology remains elusive despite extensive testing,and the diagnosis of idiopathic erythrocytosis(IE)is ruled out.
