Occurrence of Contralateral Lymph Neck Node Metastasis in Patients with Squamous Cell Carcinoma of the Oral Cavity
2014
Introduction: Squamous cell carcinoma represents about 90% of malignancies of the mouth and about 38% of the head and neck tumors. The behavior of the cancer is very aggressive, presenting early cervical metastasis and, often contralateral ranging from 0.9 to 36%. Objectives: This study aims to analyze clinical and pathological factors that may influence metastasis of squamous cell carcinoma in cervical lymph nodes and relate this occurrence in the contralateral primary tumor, with disease prognosis and the interference of this type of metastasis in the survival rate of patients with this pathology. Material and Metohds: It was conducted a retrospective study from medical records of patient…
Cancer of the Penis
2021
Penile carcinoma is a rare and aggressive disease. Its incidence is related with age over 60 and presence of comorbidities such as HPV infection. The higher incidence rate is reached in developing countries. Penile carcinoma is generally a squamous cell carcinoma and it is frequently foregone by a premalignant lesion. Because of its short time to progression, an early detection is mandatory. Good physical examination is the first step toward a correct diagnosis and staging. CT scan and chest X-ray are useful for nodal stage while US and MRI can provide a preoperative assessment of local invasion. Surgical approach depends on invasion and nodal involvement, varying from a local laser ablatio…
Is kidney a new organ target in patients with obstructive sleep apnea? Research priorities in a rapidly evolving field.
2021
Abstract The bidirectional relationship between sleep disordered breathing and chronic kidney disease (CKD) has recently gained a lot of interest. Several lines of evidence suggest the high prevalence of coexistent obstructive sleep apnea (OSA) in patients with CKD and end-stage renal disease (ESRD). In addition, OSA seems to result in loss of kidney function in some patients, especially in those with cardio-metabolic comorbidities. Treatment of CKD/ESRD and OSA can alter the natural history of each other; still better phenotyping with selection of appropriate treatment approaches is urgently needed. The aim of this narrative review is to provide an update of recent studies on epidemiologic…
Renal cell carcinoma with inferior vena cava involvement: Prognostic effect of tumor thrombus consistency on cancer specific survival
2016
Background Renal cell carcinoma forming a venous tumor thrombus (VTT) in the inferior vena cava (IVC) has a poor prognosis. Recent investigations have been focused on prognostic markers of survival. Thrombus consistency (TC) has been proposed to be of significant value but yet there are conflicting data. The aim of this study is to test the effect of IVC VTT consistency on cancer specific survival (CSS) in a multi-institutional cohort. Methods The records of 413 patients collected by the International Renal Cell Carcinoma–Venous Thrombus Consortium were retrospectively analyzed. All patients underwent radical nephrectomy and tumor thrombectomy. Kaplan–Meier estimate and Cox regression analy…
Liver Resection for Intrahepatic Cholangiocarcinoma—Single-Center Experience with 286 Patients Undergoing Surgical Exploration over a Thirteen Year P…
2021
Background: Intrahepatic cholangiocarcinoma (iCCA) accounts for about 10% of primary liver cancer. Surgery is the only potentially curative treatment. We report on our current series of 229 consecutive hepatic resections for iCCA, which is one of the largest Western single-center series published so far. Methods: Between January 2008 to December 2020, a total of 286 patients underwent 307 surgical explorations for intended liver resection of iCCA at our department. Data were analyzed with regard to (1) preoperative treatment of tumor, (2) operative details, (3) perioperative morbidity and mortality, (4) histopathology, (5) outcome measured by tumor recurrence, treatment of recurrence and su…
SEXUALHORMONE-BINDING GLOBULINE (SHBG) AND FREE TESTOSTERONE (FTE) IN PATIENTS WITH ULLRICH TURNLR SYNDROME(UTS) RECEIVING OXANDROLONE
1993
Our investigation showed that the concentration of SHBG decreased in healthy girls and boys at increased FIE concentrations. It was therefore the aim of the present study to examine the effects of anabolic steroid oxandrolone in SHBG and FTE concentrations in patients with Turner's syndrome. The normal dose to promote growth in patients wilh UTS is 0,1 mg/kg/BW. Our patients received a very low dose of 1,25 mg oxandrolone/doy. We analysed 21 sera of UTS patients. The determination of SHBG concentrations was performed with the IRMA (Famos diagnostics, Oulunsala, Finnland), the concentration of FTE was determined with the RIA (Immunchem.Corporation, Carson, USA). In 7 untreated UIS patients w…
Assessment of myometrial infiltration and preoperative staging by transvaginal ultrasound in patients with endometrial carcinoma
1995
In recent years, the incidence of carcinoma of the endometrium has shown an upward trend, such that it is currently the most frequently encountered malignant tumor of the female genital tract. An accurate preoperative diagnosis of the extent and spread of such carcinomas is of crucial importance for the selection of a therapeutic approach appropriate to the stage and infiltration of each particular tumor. In a prospective study of 80 patients with a carcinoma of the endometrium, performed at the Department of Obstetrics and Gynecology of the University of Mainz, we compared the preoperative findings of transvaginal sonography with the postoperative histological results with respect to the f…
Oral Surgical Management of Bone and Soft Tissues in MRONJ Treatment: A Decisional Tree.
2020
Background: The aim of the present work was to analyze a 10-year retrospective series of surgically treated medication-related osteonecrosis of the jaws (MRONJ) cases, reporting the clinical outcome and success rate for each adopted procedure in order to draw a treatment algorithm that is able to standardize clinical decision making and maximize the success of oral surgical treatment of MRONJ. Methods: Different surgical approaches were categorized taking into consideration two variables a) hard tissue management (defined as debridement, saucerization or marginal resective surgery of maxillary necrotic bone) and b) soft tissue management (defined as type of flap design and related modality …
Analysis of cardiac and pulmonary complication probabilities after radiation therapy for patients with early-stage breast cancer
2009
Objective. The purpose of this study was to evaluate the radiobiological implications of clinical use of respiratory-gated techniques for postoperative radiation therapy of early-stage left-sided breast cancer after breast-conserving surgery. Material and methods. Radiation therapy treatment plans of 80 patients with early-stage breast cancer (stage I–II), receiving whole breast irradiation after breast-conserving therapy, were analyzed. The control group consisting of 47 patients received standard radiation therapy, and the respiratory-gated group consisting of 33 patients received deep inspiration-gated radiation therapy. Normal tissue complication probabilities (NTCP) for cardiac mortali…
Management of permanent teeth with necrotic pulps and open apices according to the stage of root development
2017
Background This paper analyzed the distribution of treatments for permanent teeth with necrotic pulps and open apices according to the stage of root development. Material and methods Dental records from all root canal procedures performed in permanent teeth with necrotic pulps and open apices over a period of 14 years by residents of the Speciality of Endodontics, University of Guadalajara, Mexico, were analized. Results Records from 206 treatments were mainly divided into the following 3 different stages according to criteria described by Cvek: stage IV (n = 79, 38.3%), stage V (n = 66, 32%) and stage III (n = 53, 25.7%). Few cases involved the initial stages of root development (stages I …
