The supraventricular tachycardias: Proposal of a diagnostic algorithm for the narrow complex tachycardias
2013
AbstractThe narrow complex tachycardias (NCTs) are defined by the presence in a 12-lead electrocardiogram (ECG) of a QRS complex duration less than 120ms and a heart rate greater than 100 beats per minute; those are typically of supraventricular origin, although rarely narrow complex ventricular tachycardias have been reported in the literature.As some studies document, to diagnose correctly the NCTs is an arduous exercise because sometimes those have similar presentation on the ECG. In this paper, we have reviewed the physiopathological, clinical, and ECG findings of all known supraventricular tachycardias and, in order to reduce the possible diagnostic errors on the ECG, we have proposed …
Therapy response evaluation of malignant lymphoma in a multicenter study: comparison of manual and semiautomatic measurements in CT.
2014
Purpose: Comparison of manual one-/bi-dimensional measurements versus semi-automatically derived one-/bi-dimensional and volumetric measurements for therapy response evaluation of malignant lymphoma during CT follow-up examinations in a multicenter setting. Materials and Methods: MSCT data sets of patients with malignant lymphoma were evaluated before (baseline) and after two cycles of chemotherapy (follow-up) at radiological centers of five university hospitals. The long axis diameter (LAD), the short axis diameter (SAD) and the bi-dimensional WHO of 307 target lymph nodes were measured manually and semi-automatically using dedicated software. Lymph node volumetry was performed semi-automa…
Positronen-Emissions-Tomographie zum präoperativen Staging des Ösophaguskarzinoms
2002
BACKGROUND AND OBJECTIVE Exact preoperative staging is a prerequisite for the indication as well as the choice of the appropriate operative technique for patients with esophageal carcinoma. In this prospective study we assessed whether positron emission tomography (PET) with (18)F-fluorodeoxyglucose (FDG) increases the accuracy of staging compared to standard computer tomography (CT) and leads to a different therapeutic approach. PATIENTS AND METHODS 30 patients (25 men, 5 women, median age 63 years) with histologically identified carcinoma of the esophagus (n =29) and the cardia (n = 1), respectively, were studied. All patients underwent FDG-PET imaging of the neck, chest, and abdomen as w…
The role of ceus in the evaluation of thyroid cancer: from diagnosis to local staging
2021
Ultrasound often represents the first diagnostic step for thyroid nodule evaluation in clinical practice, but baseline US alone is not always effective enough to achieve thyroid nodule characterization. In the last decades new ultrasound techniques, such as CEUS, have been introduced to evaluate thyroid parenchyma as recommended by EFSUMB guidelines, for use in clinical research field, although its role is not yet clear. Several papers show the potential utility of CEUS in the differential diagnosis of benign and malignant thyroid nodules and in the analysis of lymph node involvement in neoplastic pathology. Therefore, we carried out an evaluation of the literature concerning the role of CE…
Azartspēļu nodevu un to likuma ietekme uz kazino un pokera tiešsaites vietnēm Latvijā
2018
Azartspēles ir jebkuras spēles uz naudu, kur to spēlētājiem ir iespēja iegūt laimestu. Bieži azartspēļu laimests vairāk ir atkarīgs no veiksmes, nekā no prasmēm. Populārākās azartspēles mūsdienās ir spēļu automāti, rulete, dažādas kāršu spēles, piemēram, pokers, acīte un citas. Pēdējo gadu laikā ir aktuāla arī cīņa pret nelegālajām interneta azartspēļu vietnēm, taču joprojām atrodas personas, kas spēj atrast apvedceļus noteiktajiem ierobežojumiem un piekļūt bloķētajām nelicencētajām vietnēm, bet, tam ir nepieciešamas noteiktas zināšanas tehnoloģijās. Ne vienmēr pasaules interneta azartspēļu tirgus dalībnieki izņem licenci darbībai Latvijā. Jānorāda, ka tiešsaistes azartspēles vietnes nav ti…
Extranodal extension in N1-adenocarcinoma of the pancreas and papilla of Vater: A systematic review and meta-analysis of its prognostic significance
2016
The aim of the study was to investigate the prognostic role of extranodal extension (ENE) of lymph node metastasis in adenocarcinoma of the pancreas (PDAC) and papilla [cancer of the papilla of Vater (CPV)]. A PubMed and SCOPUS search from database inception until 5 January 2015 without language restrictions was conducted. Eligible were prospective studies reporting data on prognostic parameters in individuals with PDAC and/or CPV, comparing participants with the presence of ENE (ENE +) with those with intranodal extension (ENE). Data were summarized using risk ratios for number of deaths/recurrences and hazard ratios for time-dependent risk related to ENE+, adjusted for potential confounde…
Nuclear Medicine Methods in Scrotal Imaging
2011
In patients with acute scrotal pain scrotal scintigraphy can be used to exclude torsion of the testicle, which presents with unilateral decrease in activity on the affected side.The role of nuclear medicine methods, however, faded in the last years after the introduction of high performance color Doppler ultrasound equipment. Lymphoscintigraphy can be used in patients with testicular cancer to demonstrate the lymphatic drainage pathway of the neoplasm. Several studies suggest that 18FDG-PET/CT might have a role in the staging germ cell tumors, in identification of recurrent/residual disease, to monitor the treatment response and during the follow-up. Other investigations, however, did not c…
Einfluß der Proliferationsrate auf den Krankheitsverlauf von nodalnegativen Mammakarzinomen
1995
In 250 patients with node-negative breast cancer and no systemic adjuvant therapy the impact on the prognosis of the variables age, histological tumour type, tumour size, histological grade, receptor status and localisation of the tumour within the breast, was studied. Patients were followed over a mean period of 60 (range 7-164) months. In a subset of 124 cases additional examination of the growth fraction rate, detected by immunohistochemical determination of antibody Ki-67 and semiquantitative measurement of the stained tumour cell nuclei was performed. In 43 cases, measurement of S-phase fraction by flow cytometry was also performed. By univariate analysis, the histological tumour type …
Laparoscopic lymph node dissection should be performed before fertility preserving treatment of patients with cervical cancer
2012
Objective: The aim of this study is to assess our results of treatment of women with stage I cervical cancer > 2 cm in diameter seeking fertility preservation. Treatment consisted of Laparoscopic Pelvic and Paraaortic Lymphadenectomy (LPPLND), and when no nodal metastasis was detected, neoadjuvant chemotherapy (NACT) followed by radical vaginal trachelectomy (RVT). Patients with positive lymph nodes underwent primary chemoradiation. Methods: A cohort of women younger than 40 years of age with stage I disease > 2 cm who underwent LPPLND and either NACT and RVT or chemoradiation. Oncological outcome was evaluated prospectively. Results: Eighteen women were eligible for this study. Twelve (67%…
Clinical Recommendation Radical Trachelectomy for Fertility Preservation in Patients With Early-Stage Cervical Cancer
2012
Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of pat…
