Intensive care physicians are tasked with managing patients with complex organ disorders, necessitating a broad skill set and ongoing education. While simulation training often focuses on equipment handling, this case report highlights a critical instance of acute aortic dissection initially missed on imaging during intensive care unit (ICU) admission. An 86-year-old woman with multiple comorbidities presented with respiratory symptoms and electrolyte imbalances, ultimately requiring ICU admission. Despite initial inconclusive imaging and treatment for suspected conditions, further evaluation revealed a dissecting aneurysm of the descending aorta. This case underscores the importance of thorough diagnostic evaluation and ongoing vigilance, especially in older adults with multiple health conditions. It emphasizes the need for comprehensive education, including proactive training in image diagnosis, to recognize diverse medical presentations and potential complications. This case serves as a reminder of the evolving challenges in critical care and the necessity for continuous education and adaptability to ensure optimal patient outcomes.

Cardiac myxoma is the most common primary heart tumor in adults. Although biologically benign, they can be life-threatening by obstructing heart function. They typically develop in the left atrium and can be polypoid (causing more obstruction) or papillary (more likely to cause embolizations). Symptoms are nonspecific, and diagnosis is relatively rare. Echocardiography is essential for quick diagnosis, and surgical removal is the primary treatment with low mortality rates, excellent postoperative survival, and low recurrence rates. We report a 73-year-old woman presented to the emergency room with extreme fatigue and weight loss. Further investigations revealed a mass in the left atrium suggestive of an intracardiac tumor on a thoracic computer tomography scan. A subsequent transesophageal echocardiogram was performed, which showed a large, mobile, and friable hyperechogenic intra-auricular mass adhered to the atrial septum with moderate mitral regurgitation and moderate aortic stenosis. This case highlights the crucial role that the transesophageal echocardiogram plays in these patients by accelerating diagnosis, assisting with myxoma resolution, and confirming the complete removal of the myxoma.

Lung cancer is the second most common cancer worldwide and remains the first cause of cancer death. The diagnosis of lung cancer is mostly made following evaluation for respiratory signs and symptoms but sometimes the first presentation may be atypical. Some symptoms may be related to the invasion of adjacent structures and others caused by an autoimmune-mediated process when cross-reactivity between tumor antigens and normal nervous tissues is responsible for paraneoplastic syndromes. We present a case of a young woman with a smoking history who first manifested with two uncommon presentations of lung cancer: a paraneoplastic neurological syndrome and a hemorrhagic pericardial effusion with cardiac tamponade.

Pregabalin (PB) overdose causes mild symptoms and coma is rarely seen unless the patient has also ingested sedatives and/or has preexisting renal disease. We present a case report of a suicide attempt with PB where the patient presented in a comatose state that was successfully treated with continuous renal replacement therapy (CRRT). Treatment of PB overdose is usually supportive. However, previous reports of PB overdose have been treated with intermittent hemodialysis (IHD) in patients with preexisting renal disease. The problem with IHD is that it is only available in specialist centers and unsuitable for unstable patients. In the following case report, the patient presented to the emergency department (ED) unconscious and hypotensive. It was thought that the patient tried to commit suicide by taking an overdose of zopiclone tablets, as empty packets of zopiclone tablets were found beside the patient. There was no effect with flumazenil treatment, so the patient was intubated, mechanically ventilated, and admitted to the intensive care unit (ICU) where inotropic support was started. Despite supportive therapy, there was no improvement in the patient\'s condition. Further investigation into the patient\'s medical records uncovered prescriptions of PB. Based on this finding, plasma PB levels were measured and found to be 20 times the upper limit of the therapeutic reference range. CRRT was instituted and after 6 h of treatment the patient woke up. Hospitals with ICUs often have CRRT available in their units whereas IHD is less readily available. This case report demonstrates that CRRT is an effective method for treating PB overdose in an unconscious unstable patient that was unsuitable for transfer to another hospital.

Lung herniation is a rare complication following cardiopulmonary resuscitation (CPR) and is defined as a protrusion of lung parenchyma through the thoracic wall. This article presents a case in which a patient presented to the hospital with sepsis secondary to community-acquired pneumonia. A 74-year-old female with a background of chronic obstructive pulmonary disease (COPD) suffered a sudden pulseless electrical activity (PEA) cardiac arrest while being managed in the acute medical ward. The CT following the return of spontaneous circulation (ROSC) demonstrated multiple bilateral anterior rib fractures and herniation of the right lung through the right lateral thoracic wall. She was managed in the ICU with ventilatory and cardiovascular support for four days until she suffered a second cardiac arrest, where resuscitation was unsuccessful. In addition to this case report, a literature review was carried out, given the rarity of this pathology. The literature provides only 13 articles on lung herniation due to CPR. The most common injury pattern was anterior rib fractures leading to anterior lung herniation. In our case report, the herniation was away from the fracture site at the lateral chest wall. A common complication was surgical emphysema in several of the articles, as was in our case. The surgical intervention appears to be indicated in large hernias, incarceration, or those causing pain and respiratory compromise. In our case, conservative management was elected, given the patient\'s significant persistent cardiovascular instability unsuitable for interhospital transfer. A high index of suspicion should be adopted for patients who undergo a prolonged period of CPR, including frail patients with underlying health conditions such as chronic lung disease.

Cardiothoracic surgical critical care medicine is practiced by a diverse group of physicians including surgeons, anesthesiologists, pulmonologists, and cardiologists. With a wide array of specialties involved, the training of cardiothoracic surgical intensivists lacks standardization, creating significant variation in practice. Additionally, it results in siloed physicians who are less likely to collaborate and advocate for the cardiothoracic surgical critical care subspeciality. Moreover, the current model creates credentialing dilemmas, as experienced by some cardiothoracic surgeons. Through the lens of critical care anesthesiologists, this article addresses the shortcomings of the contemporary cardiothoracic surgical intensivist training standards. First, we describe the present state of practice, summarize past initiatives concerning specific training, outline why standardized education is needed, provide goals of such training standardization, and offer a list of desirable competencies that a trainee should develop to become a successful cardiothoracic surgical intensivist.

BACKGROUND: Delirium occurs frequently following cardiothoracic surgery, and infectious disease is an important risk factor for delirium. Surgery and cardiopulmonary bypass induce suppression of the immune response known as immunoparalysis. We aimed to investigate whether delirious patients had more pronounced immunoparalysis following cardiothoracic surgery than patients without delirium, to explain this delirium-infection association.
METHODS: A prospective matched case-control study was performed in two university hospitals. Cytokine production (tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8 and IL-10) of ex vivo lipopolysaccharide (LPS)-stimulated whole blood was analyzed in on-pump cardiothoracic surgery patients preoperatively, and at 5 timepoints up to 3 days after cardiothoracic surgery. Delirium was assessed by trained staff using two validated delirium scales and chart review.
RESULTS: A total of 89 patients were screened of whom 14 delirious and 52 non-delirious patients were included. Ex vivo-stimulated production of TNF-α, IL-6, IL-8, and IL-10 was severely suppressed following cardiothoracic surgery compared to pre-surgery. Postoperative release of cytokines in non-delirious patients was attenuated by 84% [IQR: 13-93] for TNF-α, 95% [IQR: 78-98] for IL-6, and 69% [IQR: 55-81] for IL-10. The attenuation in ex vivo-stimulated production of these cytokines was not significantly different in patients with delirium compared to non-delirious patients (p > 0.10 for all cytokines).
CONCLUSIONS: The post-operative attenuation of ex vivo-stimulated production of pro- and anti-inflammatory cytokines was comparable between patients that developed delirium and those who remained delirium-free after on-pump cardiothoracic surgery. This finding suggests that immunoparalysis is not more common in cardiothoracic surgery patients with delirium compared to those without.

The World Health Organization recommends the utilization of partograph for all laboring mothers. Partograph is a cost-effective, single sheet of paper that is used to follow maternal and fetal condition and progress of labour. Obstructed and prolonged labours are major causes of maternal deaths. These causes can be minimized by routine utilization of partograph. However, several maternal and fetal deaths occur in health facilities due to poor quality of labour follow-up. Therefore, this study aims to assess the utilization of partograph and associated factors among obstetric care providers working in Wolaita zone health facilities, Southern Ethiopia. An institution-based cross-sectional survey was conducted from April to May 2016. A pretested and structured self-administered questionnaire was used to collect the data. Data entry and analysis was conducted using SPSS Version 21.0. Logistic regression was used to identify associations. A P value <0.2 in binary logistic regression were transferred to multiple logistic regressions. Odds ratio with 95% CI, P-value <0.05 were considered as statistically significant. Of a total of 442 participants, 73.6% utilize partograph routinely. From the total variables in the study, a midwifery profession showed a significant association with the dependent variable (AOR = 4.7,95% CI:1.8-12). The utilization of partograph in the study area was low as per the World Health Organization recommendation. This study recommends that assigning midwives in the obstetric ward other than other health professionals will increase the routine utilization of partograph.

We report the case of a 56-year-old Caucasian male affected by thymoma and myasthenia gravis that developed recurrent visceral leishmaniasis 11 years after thymectomy. After treatment of each relapse with liposomal amphotericin B the PCR-Leishmania was negative and the patient showed clinical improvement. An immunologic work-up was performed showing lymphopenia with an important decrease in CD4+ T cells (52 cells/μ) and CD4/CD8 ratio (0.2). HIV test was negative. On the basis of previous thymoma and myasthenia gravis and on the basis of the immunological profile a diagnosis of Good\'s syndrome was made. Since IFNγ plays a main role in the control of Leishmania infection the production of IFNγ was evaluated. After mitogen stimulation of peripheral blood mononuclear cells the production of IFNγ was lower than normal. This is the second reported case of Good\'s syndrome with recurrent leishmaniasis and indicates that a definitive cure for leishmaniasis in patients with Good\'s syndrome is not possible. Immunologic work-up in our patient strongly suggests that relapses could be correlated with the low CD4+ T cell number and with the low IFNγ production. Immunotherapy with IFNγ or with compounds able to block the Th2 interleukin production could be a therapeutic option in these patients.

We report about a case of a compassionate off-label use of the anti-interleukin-5-agent mepolizumab in a ventilated patient with life-threatening asthma attack in eosinophilic asthma. The patient suffered from severe eosinophilic asthma and was transmitted to our hospital with an asthma attack and a life-threatening respiratory state under ventilation. Since high dose steroids had not yielded a sufficient respiratory improvement mepolizumab was administered subcutaneously. After administration of mepolizumab respiratory state and ventilation parameter improved significantly. Two days after administration the patient was weaned could be extubated 8 days later and recovered completely from the asthma attack. The presented clinical case is suggestive of future clinical trials or registry studies to evaluate potential clinical benefits of anti-interleukin-5 treatment in patients with severe exacerbations of eosinophilic asthma.
