Imaging plays an important role in the detection of coronavirus (COVID-19) pneumonia in both managing the disease and evaluating the complications. Imaging with chest computed tomography (CT) can also have a potential predictive and prognostic role in COVID-19 patient outcomes. The aim of this pictorial review is to describe the role of imaging with chest X-ray (CXR), lung ultrasound (LUS), and CT in the diagnosis and management of COVID-19 pneumonia, the current indications, the scores proposed for each modality, the advantages/limitations of each modality and their role in detecting complications, and the histopathological correlations.

A floating thrombus in a nonaneurysmal, nonatherosclerotic aorta is a rare finding and may represent an unusual source of systemic embolism. Less than 130 cases have been reported in the literature. We describe a rare case of aortic floating thrombus in the descending aorta and the proximal portion of the suprarenal abdominal aorta detected by computed tomography angiography in a 50-year-old woman who was admitted to our emergency room with epigastric abdominal pain.

Background: Malignant hyperthermia (MH) is a rare pharmacogenetic disorder which is characterized by life-threatening metabolic crises during general anesthesia. Classical triggering substances are volatile anesthetics and succinylcholine (SCh). The molecular basis of MH is excessive release of Ca2+ in skeletal muscle principally by a mutated ryanodine receptor type 1 (RyR1).

Patients with muscle pathology are a challenge for anaesthesiologists because of possible life-threatening general anaesthesia complications. A review of the current medical literature on the issue clearly indicates that increasing awareness by anaesthesiologists in recent years has led to a reduction in the occurrence of adverse events in patients with diagnostically well-defined muscle disease. On the other hand, the current emerging aspect is that the great majority of complications concern subjects with clinically non-overt (silent to mildly symptomatic) and thus undiagnosed myopathy.

To identify the genetic locus responsible for malignant hyperthermia susceptibility (MHS) in an Italian family, we performed linkage analysis to recognized MHS loci. All MHS individuals showed cosegregation of informative markers close to the voltage-dependent Ca(2+) channel (Ca(V)) α(1S)-subunit gene (CACNA1S) with logarithm of odds (LOD)-score values that matched or approached the maximal possible value for this family. This is particularly interesting, because so far MHS was mapped to >178 different positions on the ryanodine receptor (RYR1) gene but only to two on CACNA1S.

The aim of these recommendations is the revision of data published in 2002 in the "SIAARTI Recommendations for acute postoperative pain treatment". In this version, the SIAARTI Study Group for acute and chronic pain decided to grade evidence based on the "modified Delphi" method with 5 levels of recommendation strength. Analgesia is a fundamental right of the patient.

Mutations in the RYR1 gene are linked to malignant hyperthermia (MH), central core disease and multi-minicore disease. We screened by DHPLC the RYR1 gene in 24 subjects for mutations, and characterized functional alterations caused by some RYR1 variants. Three novel sequence variants and twenty novel polymorphisms were identified.

Background And Purpose: Antithrombin (AT), a glycoprotein belonging to the serpin family, blocks thrombin formation and activity at several steps. Thrombin, beside its relevant role in the coagulation cascade, exerts neurodetrimental effects through the activation of a family of protease-activated receptors, which can be implicated in stroke pathophysiology. The aims of the present study were to evaluate whether AT could reduce brain damage, ameliorate neurologic deficits, and prolong animal survival.

A secondary malignant pleural effusion is a common event in the evolution of some tumours. It is frequent in advanced phase, above all the breast cancer in the woman and the cancer of the lung in the man, but such pathology can interest also extra-thoracic cancers (ovary, colon, prostate, etc.) and the malignant lymphoma.

The correct treatment of postoperative pain, in the early period immediately following surgery, is founded on the following four principles: 1-correct diagnosis of the source and magnitude of nociception; 2-understanding of the relationship of ongoing nociception and other components of pain including anxiety, ethnocultural components, meaning, prior experience; 3-treatment by establishment and maintenance of drug level at active sites to achieve and maintain analgesia and anxiolysis as appropriate; 4-continued re-evaluation of the therapy and refinement of the approach. The PACU standard of cure requires a strict accordance between intra and postoperative analgesia. It requires "proactive preoperative plan" that includes: preoperative patient evaluation; discussion with a single patient on different treatment options; patient and family education; pre-emptive measures as indicated; intra-operative multimodal analgesia; a correct triage of analgesia, just after initial evaluation of vital parameters in PACU; re-evaluation of analgesia plan, if analgesia is inadequate; a new titration, intravenous or epidural way, in order to achieve a stable VAS < 3; plan a new analgesia scheme or confirm a preoperative plan; control of adverse events, related to analgesia plan (gastric bleeding and/or bleeding of the surgical wound site, NSAIDs-induced renal damage, respiratory depression, delayed canalisation, nausea, vomiting, excessive sedation, difficulty in bladder emptying, itchiness); a transmission of analgesia plan to ward nurses; a control quality for verify at prefixed times patients satisfaction level, analgesia performed, adverse effects percent, analgesia related, plan variations percent.

Aim: Video-assisted thoracoscopy surgery (VATS) is classically performed using general anesthesia with a double-lumen endotracheal tube to allow collapse of the operated lung. However, according to our opinion, the risks of general anesthesia with one-lung ventilation could be accepted when major thoracic operation is planned, but it should be avoided or kept at minimum when performing less invasive procedures such as video-assisted talc pleurodesis. In this paper, 2 different protocols are described in order to demonstrate the effectiveness and safety of Monitored Anesthesia Care (MAC) for performing VATS talc pleurodesis.

Unlabelled: The knowledge of pharmacodynamics and pharmacokinetics of new opioid drugs is necessary so that anaesthesiologists can choose which one to use, considering the patient's pathophysiology, the surgical procedure, and the dose required to obtain the desired effect. Aim of this review was to evaluate relevant trials on perioperative sufentanil in order to design an optimal strategy for administration.

Methods: Randomised controlled trials on perioperative sufentanil analgesia were identified by Medline research, Embase, Biosis, Scisearch and references mentioned in relevant reviews were hand searched from 1988 to June 2001.

Increase in circulating levels of endothelin (ET), a potent vasoconstrictive and mitogenic endothelium-derived peptide, has been proposed as a marker of endothelium dysfunction in acute lung injury (ALI). In the present study, we have measured levels of immunoreactive ET (irET) by radioimmunoassay, in arterial (irETart), venous (irETven) and urine (irETur) samples obtained from 10 patients with ALI and 10 healthy volunteers. Arterovenous ratio, 24 h urine excretion and renal clearance of the peptide were calculated, to obtain indices of endogenous ET metabolism.

The paper underlines the importance of continuous SvO2 monitoring by means of the insertion of a modified Swan-Ganz optic fibre catheter into the pulmonary artery. Following an analysis of the factors which regulate O2 transport and ATP formation, together with metabolism self-regulating mechanisms which intervene in periods of stress to guarantee cellular metabolic activity, the Authors underline the importance of SvO2 as an indicator of the balance between O2 demand and supply. Real-time SvO2 monitoring is therefore considered a valuable and early marker of rapidly degenerating biological processes in critical patients.
