Effects of acute CPAP application on baroreflex control of heart rate during sleep in severe obstructive sleep apnea.

2006

Baroreflex control of heart rate during sleep (baroreflex sensitivity; BRS) has been shown to be depressed in obstructive sleep apnoea (OSA), and improved after treatment with continuous positive airway pressure (CPAP). Whether CPAP also acutely affects BRS during sleep in uncomplicated severe OSA is still debatable. Blood pressure was monitored during nocturnal polysomnography in 18 patients at baseline and during first-time CPAP application. Spontaneous BRS was analysed by the sequence method, and estimated as the mean sequence slope. CPAP did not acutely affect mean blood pressure or heart rate but decreased cardiovascular variability during sleep. Mean BRS increased slightly during CPAP…

Pancoast tumour: current therapeutic options

2019

Pancoast's syndrome is caused by malignant neoplasm of superior sulcus of the lung which produces destructive lesions of thoracic inlet and comes along with the involvement of brachial plexus and stellate ganglion. Computed tomography (CT) or magnetic resonance imaging (MRI) scans can detect early lesions otherwise missed by routine radiographs and can also define the local extent or metastatic progression of the disease. Protocols involving combinations of irradiation, chemotherapy, and surgery are currently being under investigation to determine the best management.This work reviewed the current diagnostic and therapeutic approaches to Pancoast's tumors.Patients with lung superior sulcus …

Involvement of the aorta in brucellosis: the forgotten, life-threatening complication. A systematic review.

2012

Abstract Human brucellosis is a disease of protean manifestations, and has been implicated in complications and focal disease in many human organ systems. However, little is collectively known about the background, the course, the clinical characteristics, the diagnostic issues raised, and the short- and long-term therapeutic approaches in patients with aortic involvement as a complication of brucellosis. With the aim to glean from the literature useful information to better understand and manage this complication, a computerized search without language restriction was conducted using PubMed and SCOPUS. An article was considered eligible for inclusion in the systematic review if it reported…

Genetic contribution in sporadic thoracic aortic aneurysm? Emerging evidence of genetic variants related to TLR-4-mediated signaling pathway as risk …

2015

Abstract Sporadic thoracic aortic aneurysms (TAA) and dissections are one of the major causes of morbidity and mortality worldwide, especially in those older than 65 years. The presentation of TAA is varied and often silent. Thus, sporadic TAA detection is often fortuitous, with identification occurring during a routine physical examination or during an unrelated medical evaluation. Once suspected, confirmation by imaging clinical approaches is needed to allow the choose of the unique treatments for TAA, namely the surgery procedures, including elective surgery or endovascular repair before the onset of catastrophic and fatal complications, such as dissection or rupture. At present, there a…

Technical details of the hand-sewn and circular-stapled anastomosis in robot-assisted minimally invasive esophagectomy.

2020

SUMMARY The circular mechanical and hand-sewn intrathoracic anastomosis are most often used in robot-assisted minimally invasive esophagectomy (RAMIE). The aim of this study was to describe the technical details of both techniques that were pioneered in two high volume centers for RAMIE. A prospectively maintained database was used to identify patients with esophageal cancer who underwent RAMIE with intrathoracic anastomosis. The primary outcome was anastomotic leakage, which was analyzed using a moving average curve. For the hand-sewn anastomosis, video recordings were reviewed to evaluate number of sutures and distances between the anastomosis and the longitudinal staple line or gastric c…

α-Adrenoceptor Interaction of Tetrandrine and Isotetrandrine in the Rat: Functional and Binding Assays

1998

Abstract The action of 1S,1′S-tetrandrine, a bisbenzyltetrahydroisoquinoline alkaloid, on α1-adrenoceptors has been compared with that of its isomer 1R,1′S-isotetrandrine. The work includes binding assays to analyse the affinity of these products for the [3H]prazosin binding site of rat cerebral cortical membranes and functional studies on rat isolated aorta to examine the effects of both alkaloids on intracellular calcium processes related or not to α-adrenoceptor activation. A radioligand receptor-binding study showed that both compounds interacted with the α1-adrenoceptors displacing [3H]prazosin from the specific binding site. The Ki values (inhibition constants) were 0.69±0.12 and 1.6±…
