Filter by:Lesions classified as "High Grade Squamous Intra-epithelial Lesions" (HSIL) are pre-cervical lesions of the cervix, induced by infection with the Human Papilloma Virus (HPV). The detection and proper management of these lesions greatly reduces the incidence of invasive cervical cancer. Pap smear remains the most effective tool for early detection of low and high-grade cervical lesions. In Belgium, screening for cervical cancer is recommended every 3 years for women between 25 and 65 years old. HPV is a virus who possesses certain oncogenic genes who have the ability to inactivate tumor suppressor genes in the host cell. This promotes a tumorigenesis process within the tissues affected by the virus. The majority of human papillomavirus infections are transient and spontaneously cleared by host defense mechanisms, especially in the first two years after exposure. However, 10-20% of infections persist latently and may eventually lead to progression to invasive cervical cancer. Even high-grade lesions kan naturally be cleared, even more so if the patient is young and immuno-competent. Therefore, the management of HSIL lesions in young women has been modified and consists of adopting mainly a conservative attitude, with controls every 6 months for 2 years. This management makes it possible to avoid unnecessary conizations of the cervix which, in young nulliparous patients, are not devoid of heavy obstetric consequences during subsequent pregnancies (premature birth, perinatal mortality). Cervical conization will only be considered for lesions that progress during follow-up or that persist beyond 2 years. However, this type of follow-up requires that patients be compliant. Our study has two main objectives: - to determine the compliance of CHU Brugmann Hospital patients who have been proposed a conservative strategy for the management of HSIL lesions. - to identify the predictive factors for the persistence and / or progression of high-grade pre-cancerous dysplastic lesions.
Background and Aim: The overall incidence of difficult laryngoscopy in pediatric anesthesia is lower than in adults, but this risk is higher in patients younger than one year of age. In the last decade, different measurements have been used to obtain difficult laryngoscopy markers in children. In this study, we aimed to evaluate the relationship between the airway measurements (some performed by using ultrasonography (USG)) and the difficult laryngoscopic view in neonates and infants. Design: This is a prospective, single blinded, observational study. The number of patients was calculated as follows: A sample of 12 from the positive group (difficult laryngoscopy group) and 96 from the negative group (easy laryngoscopy group) achieve 80% power to detect a difference of 0.25 between the area under the ROC curve (AUC) under the null hypothesis of 0.50 and an AUC under the alternative hypothesis of 0,75 using a two-sided z-test at a significance level of 0.05. Methods: All patients which is newborn and infant age group undergoing elective surgery requiring intubation under general anesthesia are assessed. Patients' age, body mass index (BMI), thyromental distance, mandibula length, the distance between the lip corner and ipsilateral ear tragus, and the transverse length (measured by hand sign-middle-ring fingers adjacent side by side) measurements are recorded. In thyromental distance measurement, "thyroid notch" are determined by USG. The laryngoscopic view is graded by a different experienced anaesthetist who is blinded to the airway measurements. Statistical analysis: Receiver operating characteristic (ROC) curves are used to determine the best cut-off point for distance variables in the separation of difficult and easy laryngoscopy groups. Sensitivity, selectivity, positive predictive value and negative predictive values of lengths are calculated according to determined cut point.The difference between the two groups in terms of qualitative variables are evaluated by chi-square or Fisher's exact test. The normal distribution of the numerical variables are examined with the Shapiro-Wilk test. The difference between the two groups in terms of numerical variables are investigated by Mann Whitney U test. Values of p <0.05 are considered as statistically significant.
The study is designed to evaluate and validate impact factors to success and complication using ultrasound guided short-axis out-of-plane dynamic approach, and validate the impaction.
The objective of this safety long-term follow-up study was to evaluate the safety of OC-01 Nasal Spray at 6 months and 12 months post treatment in the OPP-002 study (NCT03636061).
The purpose of this study is to assess the left diastolic function at different levels of in patients affected by the acute respiratory distress syndrome (ARDS)
The purpose of this study is to determine whether plasma exchange as well as immunosuppressive therapy are effective in reducing death and end-stage renal disease (ESRD). The trial will also study whether a reduced cumulative dosing regimen of glucocorticoids is as effective as a standard disease regimen. The FDA-OOPD is one of the funding sources for this study.
Pancreatic Neuroendocrine Neoplasms (PanNEN) are a heterogeneous group of neoplasms that arise from the endocrine cells of the pancreatic gland. Non-functioning (NF-PanNEN) represents the most common forms and do not produce syndromes due to hormonal hypersecretion. Several prognostic factors have been demonstrated for NF-PanNEN. The presence of nodal metastasis and lymph node ratio are widely considered predictors of disease-free survival and even the number of positive nodes has been found to be associated with recurrence. In addition to traditional imaging exams, diagnostic work-up should include a Positron Emission Tomography/CT with 68Ga labeled somatostatin analogues, which have shown a high sensitivity and specificity while 18F-FDG PET can be associated for evaluating the possible presence of a high-grade component. Moreover, pancreatic endoscopic ultrasound (EUS) is usually part of the preoperative staging both for imaging details and cytological sampling. Therefore an accurate identification of nodal metastases preoperatively may have important implications for the extent of surgical resection and lymphadenectomy and even for a prognostic outcome. In this study the investigators will evaluate prospectively the accuracy of these diagnostic exams in detecting the lymph node status. Patients with sporadic NF-PanNEN who are candidates for surgical resection will undergo CE-CT scan, 68Ga DOTATOC (and eventually 18F-FDG) PET/MRI and EUS with FNA/B. Reference standard for defining the presence of nodal metastases is represented by pathological examination on the specimen.
This study will investigate a Clostridium difficile vaccine in adults 50 years of age and older. In half the adults, all 3 doses given are the Clostridium difficile vaccine, and in half the adults, 2 of the 3 doses are the Clostridium difficile vaccine with the other dose containing no active ingredients. The study will look at the subjects' immune response to the vaccine and assess the safety and tolerability of a 2-dose regimen of Clostridium difficile vaccine compared to a 3-dose regimen of Clostridium difficile vaccine.
This phase Ib/II trial studies the side effects of IRX-2, cyclophosphamide, and pembrolizumab work in treating participants with gastric or gastroesophageal junction cancer that has come back or that has spread to other places in the body. Interleukins, such as those found in IRX-2, are proteins made by white blood cells and other cells in the body and may help regulate immune response. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving RX-2, cyclophosphamide, and pembrolizumab may work better in treating participants with gastric or gastroesophageal junction cancer.
