Hemostasis in brain tumor surgery using the Aquamantys system
2014
Background: Adequate hemostasis in cranial and spinal tumor surgery is of paramount importance in neurosurgical practice. Generalized ooze bleeding from the surgical walls cavity, coming from neoplastic vessels or nervous tissue, may be problematic. Recent technical advances have dramatically reduced intraoperative complications related to blood loss. Several techniques are usually employed to control hemostasis in tumor surgery, including preoperative embolization, intraoperative hypotension, electrical coagulation, and local application of fibrin sealants or hemostatic matrix, which influence coagulation. Material/Methods: Our aim in this study was to evaluate the efficacy and the safety …
Intrinsic changes on automatism, conduction, and refractoriness by exercise in isolated rabbit heart.
2001
We have studied the intrinsic modifications on myocardial automatism, conduction, and refractoriness produced by chronic exercise. Experiments were performed on isolated rabbit hearts. Trained animals were submitted to exercise on a treadmill. The parameters investigated were 1) R-R interval, noncorrected and corrected sinus node recovery time (SNRT) as automatism index; 2) sinoatrial conduction time; 3) Wenckebach cycle length (WCL) and retrograde WCL, as atrioventricular (A-V) and ventriculoatrial conduction index; and 4) effective and functional refractory periods of left ventricle, A-V node, and ventriculoatrial retrograde conduction system. Measurements were also performed on coronary…
Psoriasis predisposition and occupational triggering factors in the appraisal of occupational medical expertises
2014
Summary Background Psoriasis is an immune-mediated disease with a genetic background. Local psoriatic changes can be triggered by exogenous mechanical or irritant factors. Causative occupational factors have to be distinguished from the spontaneous course of psoriasis in occupational medical evaluations. The objective of this work is to demonstrate the medico-legal grounds for a homogenous assessment. Patients and methods The presented recommendations were developed in a working group for Occupational and Environmental Dermatology (ABD) and the German contact dermatitis group (DKG) of the German Dermatologic Society (DDG) based on the German medico-legal framework. Results Causality between…
Adult Coats’ Disease Successfully Managed with the Dexamethasone Intravitreal Implant (Ozurdex®) Combined with Retinal Photocoagulation
2012
Purpose: To report a case of Coats’ disease managed with the dexamethasone intravitreal implant Ozurdex® (Allergan, Inc., Irvine, Calif., USA) combined with retinal photocoagulation. Methods: A 46-year-old female with 20/200 visual acuity was diagnosed with Coats’ disease with secondary retinal vasoproliferative tumor. An initial approach was performed with an intravitreal injection of the sustained-release dexamethasone implant Ozurdex. After reattachment of the retina, the telangiectatic vessels were treated with laser photocoagulation. Results: The patient’s visual acuity improved to 20/25 after the intravitreal Ozurdex. No further recurrences of exudation were evident through the 12-mon…
Stauffer’s Syndrome in Patient with Metastatic Prostate Cancer
2019
Cholestasis is a symptom that can be present in many conditions, such as bile duct obstruction by malignant mases, obstruction by gallstone, acute and chronic viral hepatitis, and autoimmune disorders, such as primary biliary and sclerosing cholangitis. Stauffer syndrome is a rare type of paraneoplastic syndrome that presents as cholestasis with absence of underlying disease. Classically Stauffer syndrome has been described in renal cell cancer patients. In literature cholestasis as manifestation of paraneoplastic syndrome has also been described in patients with prostate adenocarcinoma and pancreatic and bronchogenic carcinoma. Conclusions. Stauffer syndrome should be kept in mind in patie…
Role of S-adenosyl-L-methionine in the treatment of intrahepatic cholestasis.
1990
Recent studies have established the clinical efficacy of S-adenosyl-L-methionine (SAMe) in the treatment of cholestasis associated with hepatic diseases, pregnancy and the administration of estrogen-containing oral contraceptives. In 4 clinical trials involving a total of 639 patients with cholestasis due to acute or chronic liver disease, SAMe in an intravenous dose of 800 mg/day or an oral regimen of 1.6 g/day for 2 weeks was superior to placebo in relieving the symptom of pruritus and in restoring serum total bilirubin and serum alkaline phosphatase towards normal. The drug is also effective in intrahepatic cholestasis of pregnancy (ICP), with intravenous administration of 800 mg/day for…
Compromised Lung Volume and Hemostatic Abnormalities in COVID-19 Pneumonia: Results from an Observational Study on 510 Consecutive Patients
2021
Background: Hemostatic abnormalities have been described in COVID-19, and pulmonary microthrombosis was consistently found at autopsy with concomitant severe lung damage. Methods: This is a retrospective observational cross-sectional study including consecutive patients with COVID-19 pneumonia who underwent unenhanced chest CT upon admittance at the emergency room (ER) in one large academic hospital. QCT was used for the calculation of compromised lung volume (%CL). Clinical data were retrieved from patients’ files. Laboratory data were obtained upon presentation at the ER. Aim: The aim of this study was to evaluate the correlation between hemostatic abnormalities and lung involvement in pa…
Hyperhidrosis
2009
Sweating is a physiological and vital process. The basic distinction is made between two types of sweating: thermoregulatory and emotional sweating. Most of the sweat glands are of the eccrine type. They produce a thin secretion that is hypotonic to plasma (e1). Eccrine sweat glands are distributed all over the body; their highest density is in the axillary region, on the palms of the hands, and on the soles of the feet (1). Their main function is thermoregulation. Apocrine sweat glands are found primarily in the axillae and the urogenital region. These scent glands become active during puberty and secrete a viscous fluid. They are responsible for a person’s "personal," occasionally unpleas…
Procalcitonin for the diagnosis of invasive candidiasis: what is the evidence?
2017
Abstracts Procalcitonin is a widely used marker for the evaluation of infection and sepsis and to guide antibiotic therapy. During the last decade, several studies evaluated its role and diagnostic performance as a surrogate marker for the identification of Candida spp. in suspected invasive candidiasis. A low serum level and a favorable negative predictive value are the main findings for procalcitonin in this setting. The aim of this report is to provide an updated brief summary of the evidence supporting the use of PCT for the management of invasive candidiasis.
Expression pattern of receptor activator of NFκB (RANK) in a series of primary solid tumors and related bone metastases.
2011
Receptor activator of NFκB ligand (RANKL), RANK, and osteoprotegerin (OPG) represent the key regulators of bone metabolism both in normal and pathological conditions, including bone metastases. To our knowledge, no previous studies investigated and compared RANK expression in primary tumors and in bone metastases from the same patient. We retrospectively examined RANK expression by immunohistochemistry in 74 bone metastases tissues from solid tumors, mostly breast, colorectal, renal, lung, and prostate cancer. For 40 cases, tissue from the corresponding primary tumor was also analyzed. Sixty-six (89%) of the 74 bone metastases were RANK-positive and, among these, 40 (59.5%) showed more than…
