Abstract
Monocrystalline silicon is one of the most important semiconductor materials, widely used in chip manufacturing, solar panels. Slicing is the first step in making chips and the surface quality of silicon wafers directly affects the quality of later processing and accounts for a large proportion in the chip manufacturing cost. Ultrasonic vibration assisted wire saw (UAWS) is an effective sawing process for cutting hard and brittle materials such as monocrystalline Si, which can significantly improve the surface quality of silicon wafers. In order to further study the formation mechanism of the surface morphology of single crystal silicon sliced by UAWS, a new model for prediction of wafer surface morphology in UAWS slicing single crystal silicon based on mixed material removal mode is presented and verified in this paper. Firstly, the surface model of diamond wire saw tool is established by equal probability method. Then according to the equation of transverse vibration dynamics about the wire saw with ultrasonic excitation, the trajectory equation of arbitrary abrasive particles on the surface of wire saw is derived and analyzed. Thirdly, a new model for prediction of the wafer surface morphology based on mixed material removal mode is presented, which can be used to predict the wafer surface morphology of single crystal silicon sliced by UAWS. Finally, the prediction model is verified by UAWS slicing experiment, and the effects of slicing parameters such as wire saw speed, feed speed and workpiece rotate speed on the surface quality of silicon wafer were studied. It shows that the predicted wafer surface morphology and the experimental wafer surface morphology are similar in some characteristics, and the average error between the experimental and the theoretical values of the wafer surface roughness is 11.9%, which verifies the validity of the prediction model.

Introduction. The relevance of the study is due to the complexity of the differential diagnosis of Kosten's syndrome and meningioma in the area of the cerebellar bridge angle of the brain, as well as the severe suffering of patientsThe purpose of our study: development of an algorithm for the approach to the differential diagnosis of meningioma of the cerebellar angle and Kosten's syndrome.Materials and methods. To accomplish the set tasks, we examined 22 patients who complained of headache, hearing impairment, sensation of tinnitus, pain and crepitus in the temporomandibular joint during movements of the lower jaw, paresthesia of the oral and nasal mucosa. All patients were assigned studies: cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) of the TMJ according to indications.Results. Since complaints can lead patients to see doctors of various specialties, it is necessary to be able to differentiate between Costen's syndrome and a tumor of the cerebral pons-cerebral angle. In Costen's syndrome, the pain most often has an aching character, in contrast to the volumetric formations of the brain, in which the pain is burning, spreading along the branches of the facial or trigeminal nerve. One of the main methods of excluding a brain tumor is magnetic resonance imaging.Conclusions. The most significant modern method for diagnosing Costen's syndrome and meningioma of the cerebellopontine angle is magnetic resonance imaging (MRI) of the TMJ and the brain. Differential signs of Costen's syndrome are distal displacement of the head of the lower jaw, diagnosed by CBCT and MRI, as well as displacement of the articular disc (determined by MRI). A meningioma of the cerebellopontine angle is indicated by the burning nature of pain in half of the face, as well as confirmation of the diagnosis by magnetic resonance imaging of the brain.

Introduction. According to the literature, oxidative stress is described as one of the main factors in the pathogenesis of chronic suppurative otitis media, supporting the inflammatory process at the local level. The transition of inflammatory mediators to the systemic level is associated with the risk of developing ear purulent-destructive complications. The study of the products of lipid peroxidation in comparison with morphological changes in the structures of the temporal bone will justify the tactics of the operation.Aim. Comparison of the levels of lipid peroxidation products at the local and systemic levels in chronic suppurative otitis media, depending on the nature of pathomorphological changes in the structures of the temporal bone.Materials and methods. A prospective study of 130 patients with chronic suppurative otitis media at the age of 20-62 years with a verified diagnosis of chronic suppurative otitis media, admitted for surgical treatment, was carried out. To study the indicators of oxidative stress at the systemic level, the blood serum of patients was used; at the local level, the bone biomaterial obtained from patients during the surgical treatment of chronic suppurative otitis media was used. The quantitative determination of the primary, secondary and final products of peroxidation was carried out in the groups of patients with separate registration of lipoperoxides in the heptane and isopropanol phases of the lipid extract by spectrophotometry.Results and discussion. In the observation of patients with morphological signs of purulent destruction of the temporal bone, not only a local level of inflammation activity, but also a systemic level of an unfavorable outcome was revealed in two variants: osteoproliferation or osteonecrosis of the bone tissue of the temporal bone in chronic purulent otitis media with a constant threat to the patient's life due to intracranial purulent complications.Conclusion. The appearance in low concentrations of lipid peroxidation products in serum in patients with chronic purulent otitis media substantiates the need for a behind-the-ear approach in reconstructive-sanitizing otosurgery even with minimal clinical manifestations and CT scan data, since at the preclinical level it confirms the osteonecrotic type of bone remodeling with the risk of delayed death.

Introduction. Today the high prevalence of benign vocal fold lesions is shown (up to 55-70%). The possibilities of surgical management of this pathology are very extensive. Laser technologies are becoming more and more popular among high-tech treatment methods. However the comprehensive postoperative management of these patients is equally important.The aim of the study was to assess the features of the postoperative period in patients undergoing the endolaryngeal surgery using a semiconductor laser with a wavelength of 445 nm.Material and methods. On the basis of Saint-Petersburg Research Institute of Ear, Throat, Nose and Speech from February to June 2021 20 patients with benign vocal fold lesions 6 women and 14 men from 24 to 67 years old were examined and treated. All the patients underwent endolaryngeal surgery with direct microlaryngoscopy using a new semiconductor 445 nm laser in an inert gas atmosphere (intraoperative helium supply). After surgical treatment, the patients observed vocal rest, received antiinflammatory, antibacterial therapy, inhalations, as well as the drug Homeovox® according to the standard scheme.Conclusion. Endolaryngeal surgery with the removing of benign vocal fold lesions using a semiconductor laser with a wavelength of 445 nm has been proven to be safe and effective. According to the results of video laryngostroboscopy, acoustic analysis of the voice (the questionnaire “Voice handicap index-30”) it was noted that the laryngeal functions were restored in a short time. The inclusion of Homeovox® in the complex postoperative treatment had a favorable effect on the restoration of the phonatory function.

Introduction. Importance of the search effective methods of treating chronic adenoiditis in children is associated with a high incidence and risk of developing complications. Treatment of chronic adenoiditis are described in the literature, but the advantages of any of them are inconclusive, which leads to the search for additional more progressive methods.Objective. To increase the effectiveness of the treatment of chronic adenoiditis using complex therapy of non-drug methods in combination with the herbal preparation Tonsilgon N.Materials and methods. Biochemical changes in lymphoid tissue were studied on biopsy material in 111 children with chronic adenoiditis, grade 3 adenoid hypertrophy, directed to planned surgical treatment. In the preoperative period, patients were divided into 4 groups: Group 1-control group, patients who received conventional methods of treatment; 2-study group, patients who additionally used low-frequency ultrasound irrigation of the nasal cavity and nasopharynx with photochromotherapy; The third group, patients who received the herbal preparation tonsilgon N (drops) as preoperative therapy; The fourth group study underwent low-frequency ultrasound irrigation of the nasal cavity and nasopharynx in combination with photochromotherapy and took the drug Tonsilgon N in an age-related dosage.Results and discussion. When comparing the results of biochemical studies, an increase in the products of lipid peroxidation was noted in patients of the first group, which was regarded as a factor in the protracted course of the disease. The use of targeted phytoniring drugs in combination with low-frequency ultrasonic cavitation and photochromotherapy in complex therapy significantly modulates the processes of lipid peroxidation and can potentiate the antioxidant protection of cells.Conclusion. Objective data were obtained for the first time on biochemical changes in lymphoid tissue for various methods of therapy indicate the prospects of using non-drug methods in combination with a herbal preparation in the complex therapy of chronic adenoiditis.

Gastroesophageal reflux disease (GERD) is a disease of the gastrointestinal tract caused by the discharge of stomach contents into the esophagus. In GERD, both esophageal and extraesophageal manifestations are widespread, but, unfortunately, the latter are less well known. About one third of GERD patients have extraesophageal symptoms, which can occur even in the absence of the usual esophageal symptoms of GERD, which makes diagnosis difficult. The most common of these is laryngitis. In addition to reflux laryngitis, laryngopharyngeal reflux (LFR) can cause the development of contact granulomas, laryngeal stenosis, functional dysphonia, vocal fold nodules, Reinecke's edema, and laryngeal neoplasms. These symptoms disappear after taking antireflux therapy, but there is still no consensus on its duration.Aim. To evaluate the results of treatment of laryngeal manifestations of LFR with omeprasole 20 mg 30 minutes before meals in the morning.Methods. The study involved 531 patients with complaints of hoarseness, of which women 337 - 63.5%, men 194 - 36.5%. We prescribed omeprasole 20 mg 30 minutes before meals in the morning for 6 weeks. Patients were questioned using the Reflux Symptom Index (RSI) questionnaire and indirect laryngoscopy with an assessment of laryngeal changes according to the Reflux Signs Scale (RSS).Results. There was a statistically significant decrease in hoarseness 1 week after treatment, which continues to decrease 6 weeks after the initiation of treatment when evaluating the data on the RSI questionnaire. There was no statistically significant difference in the laryngoscopic picture before the start of treatment and after 1 week of treatment according to RSS; a statistically significant decrease in the quantitative assessment of RSS was revealed 6 weeks after the initiation of treatment.Conclusions. Omeprasole at a dose of 20 mg in 30 minutes reduces the symptoms of LFR already after 1 week, the decrease in the severity of symptoms continues by 6 weeks of its use. Improvement of the laryngoscopic picture with the appointment of omeprazole 20 mg 30 minutes before meals occurs by the 6th week of its use. A positive correlation was found between the severity of LFR symptoms, including hoarseness, and the severity of changes in the laryngoscopic picture.

Introduction. Carpal tunnel syndrome (CTS) is a neurological disease associated with tunnel mononeuropathies. There are various proven treatment regimens for patients with the use of conservative and surgical methods of treatment. Studies devoted to a comparative analysis of the effectiveness of methods of conservative therapy in patients with CTS are not enough to choose a treatment strategy.Purpose of the study. To study the therapeutic efficacy of wearing a wrist orthosis with and without the use of NSAIDs in the treatment of patients with CTS.Materials and methods. The study involved 40 patients (the average age of the participants was 32.8 ± 4.3 years) with a primary diagnosis of CTS, who were admitted to the neurological department of of the St Petersburg State Budgetary Healthcare Institution “Elizavetinskaya Hospital”, the Department of Medical Rehabilitation of St. Petersburg State Budgetary Healthcare Institution “St. Luke’s Clinical Hospital” in the period from 2017 to 2021. Patients were randomized into two comparable groups for complex conservative treatment and observation for 2 months of the dynamics of neurological symptoms, pain scale, QuickDASH questionnaire and neurophysiological parameters. The first group of patients received NSAIDs (Nimesil), 1 sachet (100 mg of nimesulide) twice a day after meals for 4 weeks, and the second group – NSAIDs with the imposition of a wrist orthosis for 4 weeks.Results. The study involved 40 patients. The average age of the participants was 32.8 ± 4.3 years (range from 20 to 48 years). Neurophysiological indicators in the studied groups at the screening stage were comparable: distal latency of the M-response (DLMO), ms; the amplitude of the negative peak of the M-response, mV; sensory latency (SL), ms and sensory impulse conduction velocity (SSPI), m / s: 5.7, 5.3, 3.5 and 31.8 in the first group and 5.4, 5.5, 3.8 and 32.4 in the second group (p > 0.05 when comparing the corresponding parameters). After the course of treatment, significant changes in the analyzed parameters were revealed (p < 0.05).Conclusions. In patients who received nimesulide and wore a wrist brace, the effectiveness of treatment was higher.

Introduction. The present study analyzed the possibility of using neuropsychological tests to assess postoperative cognitive dysfunction. New data were obtained: in the postoperative period, hippocampal memory impairments predominate in patients, which makes it expedient to use methods for diagnosing primary modal-nonspecific memory disorders in patients who are to undergo neurosurgical intervention on the spinal cord.The aim of the study to evaluate the influence of surgery with anesthesia on the cognitive functions of middle-age patients.Materials and methods. The study included 20 middle-aged patients. All patients had to undergo spinal surgery. Patients received total intravenous anesthesia with propofol induction (4–12 mg/kg/hr). Cognitive functions before and after the operation were made with the use of the MoCA, TMT A and B, FCSRT, state-trait anxiety inventory test (STAI).Results. The development of POCD was noted in 15% of cases. The patients showed a decrease in the FCSRT prompt index (1st day = 87 ± 9.0; 2nd day = 83 ± 15; p = 0,0005), while the overall severity of cognitive impairments (total score of MoCA) did not change significantly (standard deviation according to MoCA: 24.25 ± 2.86 on day 1 and 24 ± 3.24 on the second day, p = 0.61). The RT level decreased by day 2: 44.65 ± 7.4 versus 41.1 ± 8.2 (p = 0.001). Correlation analysis did not show the relationship between the age of patients, education level, comorbidity and development of POCD; however, the duration of anesthesia was associated with a decrease in MoCA scores (Pearson’s correlation coefficient r = –0.44; p = 0.050).Conclusion. Thus, our study shows that the study of hippocampal memory impairments is important in patients with POCD. These data differ from the data of researchers presented earlier, where the most important clinical manifestations of POCD are considered to be a decrease in attention and speed of mental processes. Of course, the small sample size dictates the need for additional research.

Introduction. Kinesitherapy (KT) – one of the leading areas of patient care with chronic nonspecific (musculoskeletal pain) low back pain. For chronic lumbar pain, a standard KT is commonly used, that includes group sessions with a medical specialist. Often not taking into account the individual characteristics of patients, their attitude to KT, does not use a backpain education program in combination with KT (extended KT). Physical activity and hypodynamia are compared in patients with chronic nonspecificlow back pain in standard KT and extended KT.Aim of study is to assess the effectiveness of the standard and extended KT in the enhancement of physical activity.Materials and methods. 71 patients were observed (17 men and 54 women, average age 55.09 ± 13 years) with chronic nonspecific low back pain. Patients received non-steroidal anti-inflammatory drugs (NSAIDs) as painkillers. 34 patients received a standard KT, 37 patients – an extended KT. Patients were asked to complete the Numeric Pain Rating Scale (NPRS), the Oswestry Low Back Pain Disability Questionnaire, and the International Physical Activity Questionnaire (IPAQ) at baseline, after 7 days and 90 days.Results and discussion. In the extended KT group, physical activity increased from 11 (7–16) points to 16 (13–19) points after 7 days (p = 0.001) and up to 23 (15–26) points after 3 months (p = 0.0002). There has been a statistically significant decrease in the proportion of patients with hypodynamy (p = 0.0015). There is no statistically significant increase in physical activity in the standard therapy group. The use of NSAIDs in non-specific low back pain is discussed, the effectiveness of the use of dexketoprofen (Dexalgin) during lumbar pain is noted.Conclusion. In the case of nonspecific low back pain, the extended KTimprovesphysical activity and reduce hypodynamy.
