RESUMEN
Background/Objectives: The complexity of trauma-induced coagulopathy (TIC) is a result of the unique interactions between the patient, trauma, and resuscitation-related causes. The main objective of trauma resuscitation is to create the optimal milieu for both the development of immediate reparatory mechanisms and the prevention of further secondary injuries. Endotheliopathy represents one of the hallmarks of trauma-induced coagulopathy, and comprises endothelial dysfunction, abnormal coagulation, and inflammation, all of which arise after severe trauma and hemorrhagic shock. Methods: We retrospectively and descriptively evaluated 217 patients admitted to the Bucharest Clinical Emergency Hospital who met the Berlin criteria for the diagnosis of multiple trauma. Patients with high suspicion of auto-heparinization were identified according to the dynamic clinical and para-clinical evolution and subsequently tested using rotational thromboelastometry (ROTEM). The ratio between the clot formation time (CT) was used, obtained on the two channels of interest (INTEM/HEPTEM). Results: Among the 217 patients with a mean age of 43.43 ± 15.45 years and a mean injury severity score (ISS) of 36.98 ± 1.875, 42 patients had a reasonable clinical and para-clinical suspicion of auto-heparinization, which was later confirmed by the INTEM/HEPTEM clotting time ratio in 28 cases (12.9% from the entire study population). A multiple linear regression analysis highlighted that serum lactate (estimated 0.02, p = 0.0098) and noradrenaline requirement (estimated 0.03, p = 0.0053) influenced the CT (INTEM/HEPTEM) ratio. Conclusions: There is a subset of multiple trauma patients in which the CT (INTEM/HEPTEM) ratio was influenced only by serum lactate levels and patients' need for vasopressor use, reinforcing the relationship between shock, hypoperfusion, and clotting derangements. This emphasizes the unique response that each patient has to trauma.
RESUMEN
Background and Objectives: Obstructive sleep apnea (OSA) is a prevalent sleep-disordered breathing pathology with significant clinical consequences, including increased cardiovascular risk and cognitive decline. Continuous positive airway pressure (CPAP) is the gold-standard treatment, but alternative strategies are sometimes needed for patients intolerant to CPAP. Drug-induced sleep endoscopy (DISE) is a key diagnostic tool for assessing upper airway obstruction in OSA patients and subsequently tailoring a surgical approach, with sedation protocols playing a crucial role in its efficacy and results accuracy. This study aimed to investigate the effect of adding remifentanil to a propofol target-controlled infusion (TCI) regimen on the sedation parameters and procedural outcomes of DISE. Materials and Methods: The study was conducted at the Central University and Emergency Military Hospital "Dr. Carol Davila" and Ria Clinic in Bucharest between July 2021 and October 2023. Thirty-one patients were enrolled and randomised into two groups: a propofol group (P group, n= 11) and a remifentanil-propofol group (R-P group, n = 20). DISE was performed using standardised protocols, sedative drugs were administered in TCI mode, and data on sedation levels, respiratory and cardiovascular parameters, and procedural incidents were collected. Results: The addition of remifentanil at 1 ng/mL effect-site concentration significantly reduced the effect-site concentration of propofol required for adequate sedation (3.4 ± 0.7 µg/mL in the P group vs. 2.8 ± 0.6 µg/mL in the R-P group, p = 0.035). The time to achieve adequate sedation was also shorter in the R-P group (7.1 ± 2.5 min vs. 9.5 ± 2.7 min, p = 0.017). The incidence of cough, hypoxemia, and cardiovascular events did not significantly differ between the two groups. Conclusions: Adding remifentanil to a propofol TCI regimen for DISE effectively reduces the required propofol effect-site concentration and shortens sedation time without increasing the risk of adverse events. This combination may enhance the safety and efficiency of DISE, offering a promising alternative for patients undergoing this procedure.

Trace elements are essential for several physiological processes. To date, various data have suggested that inadequate levels of trace elements may be involved in the pathogenesis of different chronic diseases, including immune-mediated ones, or may develop during their course. Systemic sclerosis (SSc) is a complex autoimmune multisystemic disease, primarily characterized by microvascular dysregulation, the widespread activation of the immune system and tissue fibrosis. According to the latest reports regarding the pathogenesis of SSc, the main pathophysiological processes-inflammation, vasculopathy and fibrosis-may include various trace element derangements. The present literature review aims to update the available data regarding iron, zinc, copper and selenium status in SSc as well as to underline the possible implications of these trace elements in the complexity of the pathogenic process of the disease. We observe that the status of trace elements in SSc plays a crucial role in numerous pathogenic processes, emphasizing the necessity for proper monitoring and supplementation. The reported data are heterogenous and scarce, and future studies are needed in order to draw clearer conclusions about their complete spectrum.

Coagulopathy and traumatic brain injury (TBI) are complexly intertwined. In isolated TBI, coagulopathy may contribute to hemorrhagic lesion development, progression, or recurrence, as it may lead to a particular pattern of coagulopathy called TBI-induced coagulopathy (TBI-IC). We performed a retrospective and descriptive evaluation of 63 patients admitted to the Emergency Clinical Hospital Bucharest with the diagnosis of moderate/severe brain injury. In addition to demographic data, all included patients had a complete paraclinical evaluation that included rotational thromboelastometric (ROTEM) blood-clot analysis. The platelet component (PLTEM) and the endotheliopathy activation and stress index score (EASIX) were calculated. These parameters were presented comparatively according to survival at 30 days and helped define the two study groups: survivors and non-survivors at 30 days. The contribution of platelets to clot strength is derived from maximum clot elasticity (MCE) and maximum clot firmness (MCF). MCE is defined as (MCF × 100)/(100 - MCF), and PLTEM is defined as EXTEM MCE-FIBTEM MCE. EASIX is a novel biomarker recently studied in TBI patients, calculated according to the following formula: lactate dehydrogenase (U/L) × creatinine (mg/dL)/platelets (109 cells/L). Regarding the demographic data, there were no significant differences between the survivors and non-survivors. All ROTEM parameters related to clot amplitude (A5, A10, A20, MCF in EXTEM and FIBTEM channels) were higher in the group of patients who survived. Also, PLTEM was decreased in the group of deceased patients (89.71 ± 22.86 vs. 132.3 ± 16.56 p < 0.0001). The cut-off point determined with the ROC curve is 114.10, with a sensitivity of 94.74% and a specificity of 93.18%, for the detection of the negative prognosis (death at 30 days). The EASIX score was significantly higher in the patients who survived the traumatic event, with a median difference value of 1.15 (p < 0.0001). The ROC analysis of this biomarker highlights a cut-off point of 2.12, with a sensitivity of 88.64% and a specificity of 94.74% (AUC = 0.95, p < 0.0001), for the prediction of mortality. The comparative analysis of the two studied markers was performed using the Cox proportional hazard ratio and highlighted the greater influence that PLTEM has on survival time (b value = -0.05, p < 0.0001) compared to EASIX (b value = 0.49, p = 0.0026). The present retrospective study indicates the potential of the TBI-IC reflecting parameters PLTEM and EASIX as markers of mortality prognosis. Larger prospective studies are needed to confirm their combined prognostic value and use in decision-making and reduction in the burden of disease by adequate allocation of resources in a personalized and timely manner.

PURPOSE OF REVIEW: Thiamine is a crucial component in cellular energy metabolism, serving as a cofactor for multiple enzymatic processes and also having a role in regulating neuronal and neuromuscular transmission. Also it exerts antioxidant proprieties. The objective of this review is to consolidate and assess the most recent research concerning the consequences of insufficient thiamine levels for critically ill patients and to examine thiamine-related interventions. RECENT FINDINGS: Recent studies have unveiled a noteworthy association between thiamine deficiency and unfavorable consequences, such as heightened morbidity and fatality rates. The aforementioned deficiency exhibits a significant presence in medical situations such as starvation and alcohol use disorder, but also in patients during critical illness. Thiamine deficiency can have significant metabolic implications resulting in compromised energy generation and organ dysfunction, warranting prompt recognition and management. SUMMARY: Thiamine deficiency may not be recognized in critical care. Timely identification and management are imperative to mitigate adverse outcomes and improve patient prognosis. Thiamine may offer benefits for specific patient groups at higher risk of deficiency. Future studies should focus to establish optimal dosing, timing, and monitoring strategies on understanding the pathophysiological changes associated with thiamine deficiency in ICU patients and clarify its role in improving clinical outcomes.

Background and Objectives: Impaired cognition and pain after surgery contribute to prolonged hospital stays and increased mortality rates. Thus, the development of preemptive algorithms for reducing their impact should be prioritized. The main objectives of the present study were to evaluate the efficiency of using virtual reality (VR) to treat postoperative cognitive decline and pain perception. Materials and Methods: The study was a prospective, monocentric, clinical study that included 51 patients who have undergone major abdominal surgery. The patients were divided into two groups: Control (n = 25) and VR (n = 26). The VR sessions consisted of 5-8 min exposure at 24-48 h after surgery. We considered the outcome variables, the mini-mental state examination, and visual analogue scale at 24-48 h after surgery. The dependent variables were age, social status, educational level, and duration of surgery. Results: We did not observe any differences in postoperative cognition deficit with regard to VR. The VR, however, successfully reduced postoperative pain intensity. Moreover, the patients' age, surgery duration, level of education, and social status influenced the MMSE score at 24-48 h after surgery. Conclusions: Even if using VR does not alleviate short-term postoperative cognitive impairments, it could affect pain perception. Further studies are needed to support the use of VR in perioperative contexts.

The administration of intravenous lipid emulsion (ILE) is a proven antidote used to reverse local anesthetic-related systemic toxicity. Although the capacity of ILE to generate blood tissue partitioning of lipophilic drugs has been previously demonstrated, a clear recommendation for its use as an antidote for other lipophilic drugs is still under debate. Venlafaxine (an antidepressant acting as a serotonin-norepinephrine reuptake inhibitor (SNRI)) and quetiapine (a second-generation atypical antipsychotic) are widely used in the treatment of psychotic disorders. Both are lipophilic drugs known to induce cardiotoxicity and central nervous depression. We report the case of a 33-year-old man with a medical history of schizoaffective disorder who was admitted to the emergency department (ED) after having been found unconscious due to a voluntary ingestion of 12 g of quetiapine and 4.5 g of venlafaxine. Initial assessment revealed a cardiorespiratory stable patient but unresponsive with a GCS of 4 (M2 E1 V1). In the ED, he was intubated, and gastric lavage was performed. Immediately after the admission to the intensive care unit (ICU), his condition quickly deteriorated, developing cardiovascular collapse refractory to crystalloids and vasopressor infusion. Junctional bradycardia occurred, followed by spontaneous conversion to sinus rhythm. Subsequently, frequent ventricular extrasystoles, as well as patterns of bigeminy, trigeminy, and even episodes of non-sustained ventricular tachycardia, occurred. Additionally, generalized tonic-clonic seizures were observed. Alongside supportive therapy, antiarrhythmic and anticonvulsant therapy, intravenous lipid emulsion bolus, and continuous infusion were administered. His condition progressively improved over the following hours, and 24 h later, he was tapered off the vasopressor. On day 2, the patient repeated the cardiovascular collapse and a second dose of ILE was administered. Over the next few days, the patient's clinical condition improved, and he was successfully weaned off ventilator and vasopressor support. ILE has the potential to become a form of rescue therapy in cases of severe lipophilic drug poisoning and should be considered a viable treatment for severe cardiovascular instability that is refractory to supportive therapy.
RESUMEN
Considering the prioritization of life-threatening injuries in trauma care, secondary dysfunctions such as ventilator-induced diaphragmatic dysfunction (VIDD) are often overlooked. VIDD is an entity induced by muscle inactivity during invasive mechanical ventilation, associated with a profound loss of diaphragm muscle mass. In order to assess the incidence of VIDD in polytrauma patients, we performed an observational, retrospective, longitudinal study that included 24 polytraumatized patients. All included patients were mechanically ventilated for at least 48 h and underwent two chest CT scans during their ICU stay. Diaphragmatic thickness was measured by two independent radiologists on coronal and axial images at the level of celiac plexus. The thickness of the diaphragm was significantly decreased on both the left and right sides (left side: -0.82 mm axial p = 0.034; -0.79 mm coronal p = 0.05; right side: -0.94 mm axial p = 0.016; -0.91 coronal p = 0.013). In addition, we obtained a positive correlation between the number of days of mechanical ventilation and the difference between the two measurements of the diaphragm thickness on both sides (r =0.5; p = 0.02). There was no statistically significant correlation between the body mass indexes on admission, the use of vitamin C or N-acetyl cysteine, and the differences in diaphragmatic thickness.
RESUMEN
Background and objectives: Postoperative cognitive dysfunction (POCD) represents a decreased cognitive performance in patients undergoing general anesthesia for major surgery. Since liver cirrhosis is associated with high mortality and morbidity rates, cirrhotic patients also assemble many risk factors for POCD. Therefore, preserving cognition after major surgery is a priority, especially in this group of patients. The purpose of this review is to summarize the current knowledge regarding the effectiveness of perioperative therapeutic strategies in terms of cognitive dysfunction reduction. Data Collection: Using medical search engines such as PubMed, Google Scholar, and Cochrane library, we analyzed articles on topics such as: POCD, perioperative management in patients with cirrhosis, hepatic encephalopathy, general anesthesia in patients with liver cirrhosis, depth of anesthesia, virtual reality in perioperative settings. We included 115 relevant original articles, reviews and meta-analyses, and other article types such as case reports, guidelines, editorials, and medical books. Results: According to the reviewed literature, the predictive capacity of the common clinical tools used to quantify cognitive dysfunction in cirrhotic settings is reduced in perioperative settings; however, novel neuropsychological tools could manage to better identify the subclinical forms of perioperative cognitive impairments in cirrhotic patients. Moreover, patients with preoperative hepatic encephalopathy could benefit from specific preventive strategies aimed to reduce the risk of further neurocognitive deterioration. Intraoperatively, the adequate monitoring of the anesthesia depth, appropriate anesthetics use, and an opioid-sparing technique have shown favorable results in terms of POCD. Early recovery after surgery (ERAS) protocols should be implemented in the postoperative setting. Other pharmacological strategies provided conflicting results in reducing POCD in cirrhotic patients. Conclusions: The perioperative management of the cognitive function of cirrhotic patients is challenging for anesthesia providers, with specific and targeted therapies for POCD still sparse. Therefore, the implementation of preventive strategies appears to remain the optimal attitude. Further research is needed for a better understanding of POCD, especially in cirrhotic patients.

BACKGROUND: As the COVID-19 pandemic reached its peak, it became unavoidable that patients with other risk factors for severe pulmonary impairment (such as neuromuscular illnesses) would become afflicted. While the subject of myasthenic crisis secondary to COVID-19 pneumonia represents an interesting topic in the literature, we could not find consistent data that include, as a novel therapeutic approach, both intravenous immunoglobulin and plasma exchange therapy for the treatment of these two concurrent diseases. CASE SUMMARY: A 69-year-old man with known seropositive generalized myasthenia gravis, hypertension, ischaemic heart disease, NYHA class II-III heart failure, cerebrovascular disease, and recurrent urinary tract infections, was admitted to the ICU for mixed acute respiratory failure, elevated serum lactate and liver function enzymes, and severe thrombocytopenia. A SARS-CoV-2 PCR test was positive, despite a previous COVID-19 pneumonia episode, 10 months prior to the current one. The patient had a recent ICU admission for a myasthenic crisis, which required non-invasive mechanical ventilation and intravenous immunoglobulin therapy. He received supportive therapy, as well as etiological (intravenous remdesivir, plasmapheresis and intravenous dexamethasone). Fifteen days after admission, the patient was transferred to the neurological ward, whence he left 20 days later, with no apparent sequelae. CONCLUSIONS: Subsequent intravenous immunoglobulins and plasma exchange therapy appear to be effective and safe in patients with simultaneous acute myasthenic episode and COVID-19 pneumonia.
RESUMEN
INTRODUCTION: Chronic mesenteric ischemia is a rare entity with non-specific symptomatology; combined with rare etiologies, it could lead to unwarranted surgical indication. CASE REPORT: We report the case of an 85-year-old woman, with a history of hypertension, persistent thrombocytosis, atherosclerosis, and recent minor COVID-19 infection, presenting to the hospital with postprandial abdominal pain and nonspecific clinical examination findings; upon abdominal CT, superior mesenteric artery circumferential thrombosis was revealed. A bone marrow biopsy was performed due to suspected essential thrombocythemia, confirming the diagnosis. An endovascular approach was chosen as therapy option and a stent was placed in the occluded area. Dual antiplatelet and cytoreductive therapies were initiated after the intervention. Clinical course was excellent, with no residual stenosis 1 month after stenting. CONCLUSIONS: The therapeutic strategy in elderly patients with exacerbated chronic mesenteric ischemia requires an interdisciplinary approach in solving both the exacerbation and the underlying conditions in order to prevent further thrombotic events. Although the patient presented a thrombotic state, other specific risk factors such as COVID-19 related-coagulopathy and essential thrombocythemia should be considered.

BACKGROUND AND OBJECTIVES: Conditions such as trauma, burns, sepsis, or acute intoxications have considerable consequences on the endocrine status, causing "sick euthyroid syndrome". Organophosphate exposure may induce an increase in acetylcholine levels, thus altering the thyroid's hormonal status. The present study aims to identify the effects of acetylcholinesterase inhibition on thyroid hormones. MATERIAL AND METHODS: A prospective experimental study was conducted on twenty Wistar rats. Blood samples were drawn to set baseline values for thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4). Chlorpyrifos 0.1 mg/kg was administered by oral gavage to induce acetyl-cholinesterase inhibition. After exhibiting cholinergic symptoms, blood samples were collected to assess levels of cholinesterase and thyroid hormones using ELISA. RESULTS: Butyrylcholinesterase levels confirmed major inhibition immediately after intoxication compared to the baseline, certifying the intoxication. A significant increase in T4 levels was noted (p = 0.01) both at 2 h and 48 h after administration of organophosphate in sample rats. Similarly, T3 almost doubled its value 2 h after poisoning (4.2 ng/mL versus 2.5 ng/mL at baseline). Surprisingly, TSH displayed acute elevation with an afterward slow descending trend at 48 h (p = 0.1), reaching baseline value. CONCLUSIONS: This study demonstrated that cholinesterase inhibition caused major alterations in thyroid hormone levels, which may be characterized by a transient hypothyroidism status with an impact on survival prognosis.
RESUMEN
Introduction: Year 2020 has been a cornerstone in medical research due to the COVID-19 pandemic outbreak. The process of understanding the condition brought to light certain organ involvement like pulmonary or kidney damage or endocrine disbalances, while connection to other types of organ impairment remain unclear. SARS-CoV-2 has previously been incriminated in cardiac involvement, ranging from mild symptoms to more severe occurrences such as myocarditis, arrythmias or heart failure, thus complicating the acute-phase management and worsening patients' prognosis. Despite being reported as an acute manifestation in critical COVID-19, cardiac tamponade seems to also occur as a "long- COVID19" complication. The latter is a distinct yet unclear entity associated with remanent fatigue or cough, but more severe sequelae like vasculitis or polyneuropathy can occsur. Case report: We report the case of a 42-year-old patient admitted in the intensive care unit for severe respiratory and renal dysfunction one month after an initial mild episode of COVID-19. RT-PCR for SARS-CoV-2 on admission was negative. Initial imaging through CT and heart ultrasound revealed the presence of pericardial effusion but no signs of tamponade were initially obvious. Twelve hours later, the patient's state deteriorated with cardiocirculatory failure and signs of obstructive shock. Agents responsible for severe acute respiratory infection (SARI) such as influenza A and B, adenovirus, Bordetella pertussis, Mycoplasma pneumoniae, coxsackie virus, Chlamydia pneumoniae or parainfluenza viruses were ruled out. Surprisingly, RT-PCR testing for SARS-CoV-2 came back positive, although the initial test was negative. Repeated imaging confirmed massive circumferential pericardial effusion for which emergency pericardiocentesis was performed. Fluid was an exudate and histopathology reported chronic inflammation. RT-PCR testing for Mycoplasma tuberculosis in the pericardial tissue came back negative. Conclusions: The case is to our knowledge among the first to report cardiac tamponade one month after mild COVID-19 infection. The aim of this case report is to raise awareness in the medical community on the possibility of severe complications targeting major organs in the long-COVID-19 phase.
RESUMEN
Background and Objectives: The management of acute postoperative pain (APP) following major abdominal surgery implies various analgetic strategies. Opioids lie at the core of every analgesia protocol, despite their side effect profile. To limit patients' exposure to opioids, considerable effort has been made to define new opioid-sparing anesthesia techniques relying on multimodal analgesia. Our study aims to investigate the role of adjuvant multimodal analgesic agents, such as ketamine, lidocaine, and epidural analgesia in perioperative pain control, the incidence of postoperative cognitive dysfunction (POCD), and the incidence of postoperative nausea and vomiting (PONV) after major abdominal surgery. Materials and Methods: This is a clinical, observational, randomized, monocentric study, in which 80 patients were enrolled and divided into three groups: Standard group, C (n = 32), where patients received perioperative opioids combined with a fixed regimen of metamizole/acetaminophen for pain control; co-analgetic group, Co-A (n = 26), where, in addition to standard therapy, patients received perioperative systemic ketamine and lidocaine; and the epidural group, EA (n = 22), which included patients that received standard perioperative analgetic therapy combined with epidural analgesia. We considered the primary outcome, the postoperative pain intensity, assessed by the visual analogue scale (VAS) at 1 h, 6 h, and 12 h postoperatively. The secondary outcomes were the total intraoperative fentanyl dose, total postoperative morphine dose, maximal intraoperative sevoflurane concentration, confusion assessment method for intensive care units score (CAM-ICU) at 1 h, 6 h, and 12 h postoperatively, and the postoperative dose of ondansetron as a marker for postoperative nausea and vomiting (PONV) severity. Results: We observed a significant decrease in VAS score, as the primary outcome, for both multimodal analgesic regimens, as compared to the control. Moreover, the intraoperative fentanyl and postoperative morphine doses were, consequently, reduced. The maximal sevoflurane concentration and POCD were reduced by EA. No differences were observed between groups concerning PONV severity. Conclusions: Multimodal analgesia concepts should be individualized based on the patient's needs and consent. Efforts should be made to develop strategies that can aid in the reduction of opioid use in a perioperative setting and improve the standard of care.

The first case of coronavirus disease 2019 (COVID-19) was diagnosed in December 2019 in Wuhan, China. Since then, this novel infectious disease, caused by the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), has grown into a pandemic with over 330 million infected individuals worldwide, many of them with innate or acquired immunosuppression. Liver transplantation (LT) is offered as a curative therapy for end-stage liver disease as well as for acute liver failure cases. Advances in immunosuppressive therapy decreased the rates of acute and chronic graft rejection, significantly improving the quality of life. Liver transplant recipients are considered at particularly high risk for developing critical COVID-19 infection because of their chronic immunosuppressed state. Available data are heterogeneous, and the mortality rate is variably reported in the literature. There is controversy regarding whether their immunosuppressive status is a risk or a protective factor for developing severe respiratory disease. Moreover, the mechanism of action is still unclear. We report the clinical outcome of three liver transplant recipients who had COVID-19 pneumonia at different moments following liver transplantation. All patients received a standard immunosuppression regimen and specific antiviral therapy, requiring no invasive mechanical ventilation. They were discharged from the hospital with no long-term COVID-19 complications.
RESUMEN
Background: Endotracheal tube (ETT) is an important risk factor for the development of Ventilator-associated pneumonia (VAP), as it acts as a reservoir for infectious microorganisms and bypasses the host's defenses. One of the preventive measures for VAP is endotracheal tube composition. It has been reported that biofilm formation is reduced by using ETTs coated with pure silver or silver compounds. However, noble metal-alloy ETTs have not been adequately studied. Aims: To evaluate the efficacy of noble metal alloy ETT (coated Bactiguard Infection Protection ETTs) in preventing VAP compared to standard non-coated ETTs in patients requiring ≥ 48 hours of mechanical ventilation and presenting for coma due to drug intoxication. Study Design: Randomized controlled study. Methods: Participants were randomized using sealed envelopes with a concealed 1:1 allocation to either the intervention group or the control group. The intervention group used a noble metalalloy ETT, while the control group received standard ETT. The primary outcomes were the incidence of VAP (per ventilated patients) and the duration of mechanical ventilation. Results: Initially, a total of 188 patients were assessed for eligibility, and the final allocation group consisted of 180 patients, who were subsequently randomized into the intervention group (n = 97) and control group (n = 83). The incidence of VAP in the intervention and control groups was 27.83% and 43.16% (P = 0.03), and the VAP ratio per 1000 ventilation days was 51.26/1000 and 83.38/1000 (P = 0.01), respectively. The mean durations of mechanical ventilation were 3.2 ± 0.78 in the intervention group and 5.03 ± 1.88 in the control group (P = 0.22). There was no statistically significant difference between groups in terms of mortality and duration of hospital stay. Conclusion: Noble metal-alloy ETT reduces the incidence of VAP, ventilation days, and ICU stay for patients in mechanical ventilation.

Objective: Current literature indicates a connection between sarcoidosis and malignancy, prompting advanced screening in uncertain cases. Solid pseudopapillary tumors (SPT) of the pancreas are rare entities that can be confirmed by adding imaging results to immunohistochemistry staining. The aim of this article is to describe a rare association of sarcoidosis and SPT.Materials and methods: Case report.Results: A young female patient with no prior medical history presents with shortness of breath and fatigue. The diagnosis of pulmonary and hepatic sarcoidosis is placed upon laboratory and radiographic changes. Intermittent abdominal pain prompts an MRI that shows the presence of a tumoral mass in the tail of the pancreas. Surgical resection of the mass is performed and histological examination indicates a SPT, subsequently confirmed by immunohistochemistry.Conclusion: This is the third reported case of concomitant sarcoidosis and solid pseudopapillary tumor of the pancreas.

Cardiac tamponade is a rare presentation in patients with COVID-19, which may be induced by the associated exacerbated inflammatory response. The onset of cardiac tamponade may be concomitant with the acute phase of the disease or may develop subsequently as a new health condition secondary to the disease. We report four cases of cardiac tamponade that occurred late after the acute phase of the disease. One of them may be considered a post-acute complication of the disease, and three of them may be classified as a new health condition induced by COVID-19. Only two cases had a history of severe respiratory distress due to COVID-19. In all four cases, pericardiocentesis was imposed, and surprisingly, in every case, hemorrhagic fluid was evacuated. In this case, series, immune-mediated etiology is supported by histopathological results, where the main identified feature was fibrous pericarditis with inflammatory infiltrate. Only one patient included in this report died, and three of them were discharged after anti-inflammatory treatment was initiated.
