Filter by:This study will be conducted as a single blinded randomized control trial. The goal of this clinical trial is to learn about the role of low dose steroids in the resolution of tuberculous lymphadenitis. The prime questions, this clinical trial aims to answer are: - Is there any role of starting low dose steroids in resolution of lymph node size along side standard anti-tubercular drugs in patients of tuberculous lymphadenitis? - Do low dose steroid therapy in addition to standard anti-TB drugs prevents or reduces the incidence of complications? Patients presenting to the out patient department of Pak Emirates Military Hospital, Rawalpindi with tuberculous lymphadenitis will be recruited in the study after a written informed consent. Initial size of two largest lymph nodes will be measured. They will be randomized into two groups, only one of which will be receiving the low dose steroids. The patients will be followed up on a monthly basis and regression in the lymph node size, if any will be measured. The two groups will be compared at the end of the trial.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the minimally invasive diagnostic modality for the evaluation of mediastinal and hilar lymph nodes (LNs). Traditionally, EBUS-TBNA is performed using either 21 gauge (G) or 22 G needle with a major limitation of inadequate sample especially when histologic assessment of tissue architecture is necessary such as in lympho-proliferative disorders and granulomatous inflammation. Although the specimen obtained with larger bore 19 G needle has been shown to be superior in terms of more cellular material and ability to subclassify malignant disease, it has more bloody samples. Recently a novel 22 G fine needle biopsy device (EBUS-FNB) has been introduced for endobronchial use after an experience gained from gastroenterology endoscopic ultrasound reporting high yield for core biopsies. FNB device has a unique design with 3 symmetrical, fully formed, cutting heels with 3 angled points to provide acquisition of FNB specimen in the form of a core tissue which might improve the overall diagnostic yield. Herein, investigators will study the diagnostic yield and safety of the 22 G EBUS-FNB needle with 19 G EBUS needle in the evaluation of mediastinal and hilar lymphadenopathy.
The presence of calcifications, which is a relatively common feature in intrathoracic lymph nodes, typically contributes to confer them a heterogeneous aspect during endosonographic B-mode examination, but their prevalence and a possible association between calcifications and metastatic involvement has never been systematically evaluated. We hypothesize that, in patients undergoing mediastinal diagnosis or staging of suspected/known lung cancer/intrathoracic malignancies, the prevalence of lymph node metastases is similar in calcified and non-calcified lymph nodes.
The clinical study is aimed to prospectively evaluate the diagnostic accuracy and the safety of adding transbronchial mediastinal cryobiopsy to standard sampling in mediastinal diseases.
The observed indexes of the four cervical lymph node diseases were identified by informatics methods, and the differences in the diagnosis of the four diseases were evaluated, so as to improve the clinical diagnosis rate and provide a research basis for the ultrasonic evaluation of the surgical indications of cervical lymph node diseases in the future.
Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration is a procedure used to obtain tissue samples (biopsies) of lymph nodes near the airways or of lung tumours growing in close proximity to the airways. Briefly, an endoscope with an ultrasound probe which is inserted through the mouth and into the airways. Once in the airways, the ultrasound allows for identification of the optimal biopsy site; a hollow biopsy needle is then inserted into the tissue under real-time ultrasound visualization and a sample is extracted. In the investigator's centre, the extracted sample is then immediately subjected to rapid on-site evaluation (ROSE). During the ROSE procedure, a cytotechnologist uses part of the sample to make a limited number direct smears which are then rapidly stained and evaluated under a microscope by the cytotechnologist. The cytotechnologist provides an assessment of the adequacy of the sample for diagnosis. The respirologist performing the EBUS then uses this information to: i) determine whether additional sampling is required, and ii) triage any additional samples for ancillary studies as needed. A final cytopathological diagnosis is established several days later, when all of the material from the procedure (including the material not evaluated at ROSE) is examined by a cytopathologist. There are different techniques which are utilized to perform the needle aspiration biopsy. Suction aspiration (where pressure suction is applied to the needle to draw out material) which is the standard at many centres around the world and capilliary suction (where a tiny wire is drawn back slowly to create more gentle suction force) which is utilized often at LHSC. The purpose of this study is to evaluate for differences in ROSE adequacy between these two methods.
This is a study of routine neck ultrasound performed by respiratory physicians in patients with mediastinal lymphadenopathy and suspected lung cancer
The study is aimed at verifying if a pulmonologist can reliably assess the tumor burden for the extractive molecular analysis in ROSE samples obtained with endoscopic sampling procedures from intrathoracic lymphadenopathy and pulmonary nodules.
If the investigators can prove that the use of a mapleson circuit attached to a nasal trumpet employed during monitored anesthesia care leads to less sedation requirements, less procedure interruptions, shorter procedure duration, this would allow for to standardization of the type of anesthetic employed for EBUS at the investigators' institution and elsewhere. Less hypoxic episodes and less anesthetic requirements would benefit outcomes, lead to less recovery time and earlier discharges. Shorter procedural duration will create greater efficiency in the short procedure unit where the EBUS are performed.
This study compares the yield of 19-gauge needles vs 21-gauge needles during EBUS TBNA procedures.
