    Stability of the inverse resonance problem on the line

    Full text link
    In the absence of a half-bound state, a compactly supported potential of a Schr\"odinger operator on the line is determined up to a translation by the zeros and poles of the meropmorphically continued left (or right) reflection coefficient. The poles are the eigenvalues and resonances, while the zeros also are physically relevant. We prove that all compactly supported potentials (without half-bound states) that have reflection coefficients whose zeros and poles are \eps-close in some disk centered at the origin are also close (in a suitable sense). In addition, we prove stability of small perturbations of the zero potential (which has a half-bound state) from only the eigenvalues and resonances of the perturbation.Comment: 21 page

    A Spectroscopic Study of Field and Runaway OB Stars

    Full text link
    Identifying binaries among runaway O- and B-type stars offers valuable insight into the evolution of open clusters and close binary stars. Here we present a spectroscopic investigation of 12 known or suspected binaries among field and runaway OB stars. We find new orbital solutions for five single-lined spectroscopic binaries (HD 1976, HD 14633, HD 15137, HD 37737, and HD 52533), and we classify two stars thought to be binaries (HD 30614 and HD 188001) as single stars. In addition, we reinvestigate their runaway status using our new radial velocity data with the UCAC2 proper motion catalogs. Seven stars in our study appear to have been ejected from their birthplaces, and at least three of these runaways are spectroscopic binaries and are of great interest for future study.Comment: 21 pages, 1 figure, 7 tables; Accepted to Ap

    Testicular tumors occur in 1–1.5 % of cases in the structure of the general oncological morbidity among men and constitute 5 % among tumors of the urogenital tract. In Western Europe, 3–6 new cases are recorded a year per 100 thousand male population. Nevertheless, in relation to young men, this particular type of neoplasm is not only the most common oncological pathology (up to 60 % of all neoplasms), but also the main cause of cancer mortality. Risk factors for developing ovarian cancer include a family history, previous development of a tumor in the contralateral testicle, and components of testicular dysgenesis syndrome (cryptorchidism, hypospadias, spermatogenesis disorders leading to infertility). Tumors of paratesticular tissues are much less common and most of them are benign. Squamous cell carcinoma rarely develops as a primary tumor of the testis and / or paratesticular tissue, isolated cases have been described in the English literature. Secondary damage to the scrotum organs is more frequent, but such situations are usually found in patients of an older age group. This article presents the clinical case and the final results of treatment of a patient with squamous cell carcinoma of paratesticular tissue.ΠžΠΏΡƒΡ…ΠΎΠ»ΠΈ яичка Π²ΡΡ‚Ρ€Π΅Ρ‡Π°ΡŽΡ‚ΡΡ Π² 1–1,5 % случаСв Π² структурС ΠΎΠ±Ρ‰Π΅ΠΉ онкологичСской заболСваСмости Ρƒ ΠΌΡƒΠΆΡ‡ΠΈΠ½ ΠΈ ΡΠΎΡΡ‚Π°Π²Π»ΡΡŽΡ‚ 5 % срСди ΠΎΠΏΡƒΡ…ΠΎΠ»Π΅ΠΉ ΡƒΡ€ΠΎΠ³Π΅Π½ΠΈΡ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ Ρ‚Ρ€Π°ΠΊΡ‚Π°.

    Patients who practice Islam often refuse the proposed type of treatment for malignant neoplasms, citing religious reasons. Most fear that complete or partial non-retention of urine, the presence of a urostoma (ileal conduit) will violate their ritual purity and, as a result, their religious duties. The consequence of such refusal of treatment may be a lower quality of life, compared with patients of other faiths. Unfortunately, a low awareness of religious responsibilities among surgeons performing pelvic exentesis, cystectomy, prostatectomy, may prevent a full-fledged discussion of these issues before surgery. The presented review of the literature examined studies, legal aspects, and religious arguments that assist doctors in choosing treatment tactics for patients.ΠŸΠ°Ρ†ΠΈΠ΅Π½Ρ‚Ρ‹, ΠΈΡΠΏΠΎΠ²Π΅Π΄ΡƒΡŽΡ‰ΠΈΠ΅ ислам, Π·Π°Ρ‡Π°ΡΡ‚ΡƒΡŽ ΠΎΡ‚ΠΊΠ°Π·Ρ‹Π²Π°ΡŽΡ‚ΡΡ ΠΎΡ‚ ΠΏΡ€Π΅Π΄Π»ΠΎΠΆΠ΅Π½Π½ΠΎΠ³ΠΎ Π²ΠΈΠ΄Π° лСчСния ΠΏΠΎ ΠΏΠΎΠ²ΠΎΠ΄Ρƒ злокачСствСнного новообразования, ΡΡΡ‹Π»Π°ΡΡΡŒ Π½Π° Ρ€Π΅Π»ΠΈΠ³ΠΈΠΎΠ·Π½Ρ‹Π΅ ΠΏΡ€ΠΈΡ‡ΠΈΠ½Ρ‹.

    Objective. Radical nephrectomy with thrombectomy of the inferior vena cava is the preferred treatment for renal cell carcinoma with an tumor thrombosis. We describe our experience and presentreview of the literature evaluating the feasibility and safety of laparoscopic nephrectomy with inferior vena cava thrombectomy.Materials and methods. The study included 37 patients who underwent laparoscopic radical nephrectomy with level I–III thrombectomy for renal cell carcinoma in our institution from 2018 to 2021. We analyzed the clinical, radiographic, intraoperative, pathological and postoperative parameters of the patients. The literature was reviewed by the Medline search engine, PubMed, with a review of publications on laparoscopic radical nephrectomy with inferior vena cava levelI–IIIthrombectomy.Results. The mean operation time was 275 Β± 60.1 min, the median blood loss was 450 Β± 81.6 ml (β‰₯50 % of the circulating blood volume – 32.4 %). Intraoperative complications were observed during 10 (27.0 %) operations. Postoperative complications developed in 29.7 % of patients and reached gradesIII–IV according to the Clavien–Dindo scale on 13.0 % ill. All patients are activated according to the fast track rehabilitation program. The average hospital stay was 5 days. A literature review identified clinical cases and small series demonstrating the technical feasibility and safety of laparoscopic radical nephrectomy with thrombectomy in selected patients.Conclusion. Laparoscopic radical nephrectomy with thrombectomy is a technically feasible approach in carefully selected patients with level I–III tumor thrombosis. Optimal patient selection, extensive experience in laparoscopy and specialized centers are essential for the safe use of thistechnique.ЦСль исслСдования – ΠΏΡ€Π΅Π΄ΡΡ‚Π°Π²ΠΈΡ‚ΡŒ нСпосрСдствСнныС Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ выполнСния лапароскопичСской Ρ€Π°Π΄ΠΈΠΊΠ°Π»ΡŒΠ½ΠΎΠΉ нСфрэктомии с тромбэктомиСй ΠΈΠ· Π½ΠΈΠΆΠ½Π΅ΠΉ ΠΏΠΎΠ»ΠΎΠΉ Π²Π΅Π½Ρ‹ I–III ΡƒΡ€ΠΎΠ²Π½Π΅ΠΉ Π² условиях ΠΎΠ΄Π½ΠΎΠ³ΠΎ онкоурологичСского стационара.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    Introduction. Cryptorchidism is a common disease in pediatric urological and andrological practice since the issues of tactical approaches and its optimal treatment remain extremely relevant. Cryptorchidism makes a significant contribution to the structure of male infertility.Objective. To conduct a retrospective analysis of treatment results in children and adolescents with cryptorchidism.Materials & methods. This study summarises the treatment results of 8308 patients with cryptorchidism aged from 6 months to 17 years who underwent inpatient treatment in the Russian Federation and the Republic of Uzbekistan.Results. It was revealed that from 2015 to 2019, patients were admitted for surgical treatment evenly over the years. The ratio of right-sided / left-sided / bilateral cryptorchidism was 4.6 : 4.4 : 1 The inguinal form prevailed more than 6 times over the abdominal location. At the same time, 26.1% of the patients underwent surgery at the optimal time, and 9.8% were older than 10 years. More often, children are operated from an open inguinal access (95.0%), much less often β€” laparoscopically and percutaneously. Stage-by-stage treatment was carried out in 6.0% of patients.Conclusion. Thus, the approach presented in the study in the surgical treatment of cryptorchidism provided good treatment results. The number of disease relapses was 1.9% (mainly among children over 7 years old). Most surgeons are very reserved about primary orchidectomies (only 3.8% were performed)

    Purpose: to conduct a comparative analysis and to identify the epidemiological and clinical features of tick-borne encephalitis (TBE) and Lyme borreliosis as a mono- and coinfections in St. Petersburg. Materials and methods. 718 cases of TBE, 4353 cases of Lyme borreliosis and 127 combined diseases registered by the St. Petersburg epidemiological bureau in 2006-2017 were studied. Identification of combined diseases was carried out by a special software that allows to identify co-morbid diseases from the array of monoinfections. To identify clinical and epidemiological features, 144 cases of TBE, 286 Lyme borreliosis, and 43 cases of co-infection were studied. Age and sex characteristics, places of human contagion, infection rates of ticks, clinical forms of mono- and associated diseases, morbidity dynamics changes and patients’ IgM seropositivity were studied. Results. The long-term dynamics of TBE and Lyme borreliosis incidence had did not have significant upward or downward trends, it was characterized by synchronous fluctuations. The priority of the incidence of men over women is revealed. 61–69% cases of TBE and Lyme borreliosis occurred in Leningrad region, 19–30% – in the adjacent territories of Russia, 5,7–6,7% of cases were imported from other countries. High tick infection rates of TBE virus and Borrelia was revealed. Borrelia Π°nd virus of TBE and were detected in 81,6–87,5% of the examined ticks removed from patients with a later established diagnosis. Seasonal distribution of Lyme borreliosis was shifted by a month to the right in comparison with TBE. The clinical forms of both diseases did not differ in their structure from the country data, however after 2012 subclinical forms were more common in women. The proportion of non-erythematous forms of Lyme borreliosis in 2011–2015 compared with the 2006–2010 observation period increased almost 1,5-fold mainly forms, including those with co-infection. The IgM seropositivity rate in the dynamics of the disease testifies to the incomplete rehabilitation of patients. Conclusion. The clinical and epidemiological characteristics of TBE, Lyme borreliosis and combined infection in the North-West region of Russia, with the example of St. Petersburg, have certain distinctive features. The reasons for the revealed features need further study.ЦСль: провСсти ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΉ эпидСмиологичСский Π°Π½Π°Π»ΠΈΠ· ΠΈ Π²Ρ‹ΡΠ²ΠΈΡ‚ΡŒ эпидСмиологичСскиС ΠΈ клиничСскиС особСнности ΠΊΠ»Π΅Ρ‰Π΅Π²ΠΎΠ³ΠΎ энцСфалита ΠΈ Π±ΠΎΡ€Ρ€Π΅Π»ΠΈΠΎΠ·Π° ΠΊΠ°ΠΊ ΠΌΠΎΠ½ΠΎ- , Ρ‚Π°ΠΊ ΠΈ ΠΎΠ΄Π½ΠΎΠ²Ρ€Π΅ΠΌΠ΅Π½Π½ΠΎΠ³ΠΎ сочСтания этих ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΉ Ρƒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Π² Π‘Π°Π½ΠΊΡ‚-ΠŸΠ΅Ρ‚Π΅Ρ€Π±ΡƒΡ€Π³Π΅.
