Impact of chronic diuretic treatment on glucose homeostasis
2013
Background The use of diuretics for hypertension has been associated with unfavorable changes in cardiovascular risk factors, such as uric acid and glucose tolerance, though the findings in the literature are contradictory. Methods This study investigated whether diuretic use is associated with markers of metabolic and cardiovascular risk, such as insulin-resistance and uric acid, in a cohort of adults without known diabetes and/or atherosclerotic cardiovascular disease. Nine hundred sixty-nine randomly selected participants answered a questionnaire on clinical history and dietary habits. Laboratory blood measurements were obtained in 507 participants. Results Previously undiagnosed type 2 …
SIUMB guidelines and recommendations for the correct use of ultrasound in the management of patients with focal liver disease
2019
The present document describes the SIUMB (Italian Society of Ultrasound in Medicine and Biology) guidelines for the use of ultrasound in the management of focal liver disease. The aim of the paper is to provide a clinical practice guideline for Italian physicians who are approaching the ultrasound study of a focal liver lesion. In particular, these guidelines provide simple indications, recommendations and general practice advices for the correct use of contrast-enhanced ultrasound (CEUS) in this scenario. They represent the SIUMB position of the ultrasound role in the diagnostic flow charts of the principal focal liver lesions, and are in agreement with other, previously published national…
S2k guidelines for Merkel cell carcinoma (MCC, neuroendocrine carcinoma of the skin) – update 2018
2019
Merkel cell carcinoma (MCC, ICD-O M8247 / 3) is a rare malignant primary skin tumor with epithelial and neuroendocrine differentiation. The neoplastic cells share many morphological, immunohistochemical and ultrastructural characteristics with Merkel cells of the skin. The diagnosis of MCC is rarely made on clinical grounds. Histological and immunohistochemical studies are usually required to confirm the clinical suspicion. Given the frequent occurrence of occult lymph node metastasis, sentinel lymph node biopsy should be performed once distant metastasis has been ruled out by cross-sectional imaging. Primary tumors without evidence of organ metastases are treated with complete surgical exc…
Analysis of radiolucent gallstones by computed tomography for in vivo estimation of stone components.
1990
. Successful oral litholytic and other non-operative therapies of gallstones require exact determination of the stone components. Since computed tomography (CT) provides highly sensitive measurement of density, we performed a study to evaluate whether CT measurement of stone density allows a prediction of the composition of radiolucent gallstones. Twenty-eight patients presenting with 29 radiolucent gallbladder (n= 17) or common bile duct stones (n=12) were included. Prior to operative or endo-scopic therapy the attenuation values (Hounsfield Units, HU) were assessed in vivo by CT under standardized conditions (Somatom II, 125 KV, 130 mAs). After surgical or endoscopic stone removal the con…
Rational for statin use in psoriatic patients
2013
Psoriasis represents a common skin disease which is clinically manifested by chronic cutaneous lesions. It has been observed that psoriasis is associated with an increased risk of cardiovascular diseases, which is contributed to the inappropriate lipid metabolism. Statins are commonly used in clinical practice to lower cholesterol concentration and, accordingly, decrease the individual risk of developing a cardiovascular episode. There have been reports that statin administration could also result in better management of psoriasis. The observed beneficial effects are contributed to the effects on lipid metabolism, including that in skin, as well as anti-inflammatory and immunomodulatory pro…
From suspicion of angioedema to the diagnosis of lung cancer
2020
Angioedema is a localized and self-limiting oedema of the subcutaneous and submucosal tissue. Case presentation: 73-year-old man was admitted to the Division of Allergology with the diagnosis of angioedema. Detailed physical examination led to the suspicion of superior vena cava syndrome with secondary face swelling. Biopsy revealed metastasis of small cell carcinoma in superclavicular lymph nodes. Conclusions: Facial swelling, especially recurrent and non-inflammatory, is often, but not always caused by angioedema. Insightful differential diagnosis is crucial before making the final one.
Diagnostik von Pleuraergüssen und Atelektasen: Sonographie und Radiologie im Vergleich
1991
In a prospective study it was shown that chest ultrasonography is superior to conventional x-ray diagnosis of recumbent patients in diagnosing pleural effusion and lung atelectasis. In 110 supine radiographs we found a sensitivity of 47% and a specificity of 71% for right pleural effusions and a sensitivity of 55% and a specificity of 93% for left pleural effusions in comparison to 110 sonographic examinations. The results of supine radiographs in detection of atelectasis were less efficient: sensitivity for the right side: 7%; sensitivity for the left side: 13.5%. Hence, the knowledge of chest ultrasonographic diagnosis can improve the interpretation of supine radiographs.
Slow 0.1 Hz Breathing and Body Posture Induced Perturbations of RRI and Respiratory Signal Complexity and Cardiorespiratory Coupling
2020
Objective: We explored the physiological background of the non-linear operating mode of cardiorespiratory oscillators as the fundamental question of cardiorespiratory homeodynamics and as a prerequisite for the understanding of neurocardiovascular diseases. We investigated 20 healthy human subjects for changes using electrocardiac RR interval (RRI) and respiratory signal (Resp) Detrended Fluctuation Analysis (DFA, α1RRI, α2RRI, α1Resp, α2Resp), Multiple Scaling Entropy (MSERRI1−4, MSERRI5−10, MSEResp1−4, MSEResp5−10), spectral coherence (CohRRI−Resp), cross DFA (ρ1 and ρ2) and cross MSE (XMSE1−4 and XMSE5−10) indices in four physiological conditions: supine with spontaneous breathing, stand…
Can chemotherapy concomitantly delivered with radiotherapy improve survival of patients with resectable rectal cancer? A meta-analysis of literature …
2010
Summary Background There is clear evidence from two systematic reviews that radiotherapy (RT) reduces the risk of local recurrence in patients with resectable rectal cancer, though the data on survival are still equivocal. Objective To assess the effects of chemotherapy combined concomitantly with radiotherapy (CRT) on the increase of overall survival, and on the prevention of local recurrence and distant metastases. Data sources Computerized bibliographic searches of MEDLINE and CANCERLIT (1970–2008) were supplemented with hand searches of reference lists. Study selection Studies were included if they were randomized controlled trials (RCTs) comparing preoperative or postoperative CRT to p…
