Abstract
Necrotizing pancreatitis represents a severe variant of acute pancreatitis characterized by the death of pancreatic tissue (necrosis). This condition commonly stems from inflammation and damage to the pancreas, leading to the development of areas of dead tissue within the organ. Pleural effusion, on the other hand, involves the accumulation of fluid within the pleural cavity. Typically, these effusions are of mild to moderate severity and tend to occur on the left side. In the following case report, we present a 25-year-old male who was diagnosed with necrotizing pancreatitis and bilateral pleural effusion. It is important to emphasize that cardiopulmonary physiotherapy plays a crucial role in managing pleural effusion. Such interventions, which encompass breathing exercises and thoracic expansion exercises, are pivotal for optimizing lung ventilation, enhancing oxygen levels, and preventing complications such as atelectasis and pneumonia. By boosting oxygenation and improving lung compliance, physiotherapy helps reduce the risk of respiratory problems and expedites the recovery process. This approach enables young individuals to regain their lung function and overall quality of life. In this particular case, the patient received medical management and pulmonary rehabilitation, resulting in a decrease in the Modified Medical Research Council Scale score and an improvement in the six-minute walk test (6 MWT), which subsequently enhanced their quality of life.

Front Cell Infect Microbiol 2022; 12:893294. [PMID: 35755843 PMCID: PMC9226542 DOI: 10.3389/fcimb.2022.893294] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Accepted: 04/29/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND AND AIMS This study aimed to develop an interpretable random forest model for predicting severe acute pancreatitis (SAP). METHODS Clinical and laboratory data of 648 patients with acute pancreatitis were retrospectively reviewed and randomly assigned to the training set and test set in a 3:1 ratio. Univariate analysis was used to select candidate predictors for the SAP. Random forest (RF) and logistic regression (LR) models were developed on the training sample. The prediction models were then applied to the test sample. The performance of the risk models was measured by calculating the area under the receiver operating characteristic (ROC) curves (AUC) and area under precision recall curve. We provide visualized interpretation by using local interpretable model-agnostic explanations (LIME). RESULTS The LR model was developed to predict SAP as the following function: -1.10-0.13×albumin (g/L) + 0.016 × serum creatinine (μmol/L) + 0.14 × glucose (mmol/L) + 1.63 × pleural effusion (0/1)(No/Yes). The coefficients of this formula were utilized to build a nomogram. The RF model consists of 16 variables identified by univariate analysis. It was developed and validated by a tenfold cross-validation on the training sample. Variables importance analysis suggested that blood urea nitrogen, serum creatinine, albumin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, calcium, and glucose were the most important seven predictors of SAP. The AUCs of RF model in tenfold cross-validation of the training set and the test set was 0.89 and 0.96, respectively. Both the area under precision recall curve and the diagnostic accuracy of the RF model were higher than that of both the LR model and the BISAP score. LIME plots were used to explain individualized prediction of the RF model. CONCLUSIONS An interpretable RF model exhibited the highest discriminatory performance in predicting SAP. Interpretation with LIME plots could be useful for individualized prediction in a clinical setting. A nomogram consisting of albumin, serum creatinine, glucose, and pleural effusion was useful for prediction of SAP.

Abstract
Introduction: Acute pancreatitis is an inflammatory condition of the pancreas, which runs a severe course in 20% of patients, wherein it is associated with high mortality. It is associated with several pleuro-pulmonary complications with variable severity that may occur either in isolation but are frequently present in combination. Clinicians need to be aware of these complications for early and appropriate management.Areas covered: We performed a systematic search of the PUBMED database (1970-2019) to identify relevant articles focusing on pleuro-pulmonary complications that may occur in patients with acute pancreatitis. We also retrieved articles describing the pathophysiological mechanisms and treatment approach of the various complications.Expert opinion: Acute pancreatitis is usually a self-limiting disease, but the development of organ failure during the course worsens the clinical outcome. Pulmonary complications usually occur early in the course of acute pancreatitis. Clinicians need to recognize the various pulmonary complications of acute pancreatitis, early during the disease, and manage them appropriately and aggressively to improve outcomes.

Abstract
Acute pancreatitis in its severe form may lead to systemic inflammatory response syndrome and multisystem organ dysfunction. Acute lung injury is an important cause of mortality in the setting of severe acute pancreatitis. Besides lung involvement, acute and chronic pancreatitis may also lead to the involvement of other thoracic compartments, including mediastinum, pleura, and vascular structures. These manifestations are an important cause of morbidity and may pose diagnostic and therapeutic challenges. These manifestations have not been discussed in detail in the available literature. In this review, we discuss the thoracic complications of pancreatitis, including lung, pleural, mediastinal, and vascular manifestations.

Abstract
BACKGROUND The value of lung ultrasonography in the diagnosis of respiratory dysfunction and severity stratification in patients with acute pancreatitis (AP) was investigated. METHODS Over a 3-month period, 41 patients (median age: 59.1 years; 21 males) presenting with a diagnosis of potential AP were prospectively recruited. Each participant underwent lung ultrasonography and the number of comet tails was linked with contemporaneous clinical data. Group comparisons, areas under the curve (AUC) and respective measures of diagnostic accuracy were investigated. RESULTS A greater number of comet tails were evident in patients with respiratory dysfunction (P = 0.021), those with severe disease (P < 0.001) and when contemporaneous and maximum CRP exceeded 100 mg/L (P = 0.048 and P = 0.003 respectively). Receiver-operator characteristic plot area under the curve (AUC) was greater when examining upper lung quadrants, using respiratory dysfunction and AP severity as variables of interest (AUC = 0.783, 95% C.I.: 0.544-0.962, and AUC = 0.996, 95% C.I.: 0.982-1.000, respectively). Examining all lung quadrants except for the lower lateral resulted in greater AUCs for contemporaneous and maximum CRP (AUC = 0.708, 95% C.I.: 0.510-0.883, and AUC = 0.800, 95% C.I.: 0.640-0.929). DISCUSSION Ultrasonography of non-dependent lung parenchyma can reliably detect evolving respiratory dysfunction in AP. This simple bedside technique shows promise as an adjunct to severity stratification.

Abstract
This study examined the ultrastructural changes in the pulmonary mechanical barriers in a rat model of severe acute pancreatitis (SAP)-associated acute lung injury (ALI). Animals were randomized into the SAP group (n = 60) and the control group (n = 60). SAP was induced by retrograde injection of 5% taurocholic acid into the biliopancreatic duct. The morphological abnormalities assessed by histology and the lung wet/dry weight ratio and the ultrastructural abnormalities assessed by transmission electron microscope and scanning electron microscope examinations plus lanthanum nitrate tracing were compared between the two groups at 6, 12, and 24 h post-SAP induction (n = 10/group/time point). The SAP group had significantly greater extravascular effusion than the control group at each time point as assessed by the lung wet/dry weight ratio (p < .001). The severity of the tissue damage increased in the lung and pancreas over time in the SAP group (all p < .001). In the SAP group, ultrastructural damages to the endothelial, epithelial, and pleural barriers were apparent and the damages to the endothelial barrier were detected earlier than the other two barriers, suggesting its fundamental role in preventing the further development of SAP-associated ALI. Moreover, the ultrastructural abnormalities were detected earlier than symptoms and morphological changes. The ultrastructural damages in the endothelial, epithelial, and pleural barriers occurred in the early stage of SAP. The endothelial barrier is likely to be the first line to prevent the further development in this rat model of SAP-associated ALI.

Abstract
Pancreaticopleural fistula is a very uncommon complication of pancreatitis resulting from pancreatic duct disruption with leakage of pancreatic secretions into the pleural cavity. Initial conservative treatment fails in a significant number of cases. Ascending infection through the fistulous tract results in pleural empyema. The aim of this study is to investigate the relation between lengths of nonoperative management and risk of pleural empyema. The retrospective study includes our own experience as well as all case reports identified by a systematic review of the English literature from 1954 to 2012. Inclusion criteria were acute or chronic pancreatitis, whereas tumorous fistulization or complications of pancreatic surgery were kept out. A total of 113 patients were identified. There were 86 men and 27 women. The mean age was 46.5 years and 78 patients had a history of alcoholism. The mortality rate was 1.8 per cent (two of 113). Non-operative management including interventional therapy and endoscopic stenting was successful in only 40 cases (36%), whereas 73 patients (64%) finally underwent surgery. The most common procedure was distal pancreatectomy (32 of 73). Pleural empyema occurred in 17 cases. Successful nonoperative management had a mean length of 5.5 weeks, whereas surgery was performed after an average of 10.9 weeks of failed conservative efforts. Initial nonoperative therapy was significantly longer in patients eventually sustaining empyema (17 weeks, P < 0.001) and all needed surgical intervention. Prolonged nonoperative treatment is associated with a noteworthy risk of septic complications such as pleural empyema. Further improvement seems achievable by reducing the time gap between fruitless conservative efforts and surgical intervention.

Abstract
OBJECTIVE Adult respiratory distress syndrome (ARDS) secondary to acute pancreatitis is associated with a poor prognosis. We hypothesized that extracorporeal life support (ECLS) may be an effective treatment option for the most severe cases of pancreatitis-induced ARDS. METHODS We reviewed 8 cases of pancreatitis-induced ARDS that were treated with ECLS at our institution. We collected data on demographics, comorbidities, hemodynamic parameters, and ventilatory support used before ECLS. Our outcome measures for this study included survival to discharge, length of ECLS run, days undergoing mechanical ventilation, days in an intensive care unit, total length of hospital stay, adjunct therapies and procedures, and complications. RESULTS Overall, 5 of the 8 patients (63%) survived to discharge. Seven of the 8 patients underwent venovenous ECLS, and 1 underwent venoarterial ECLS. The overall mean length of ECLS was 9.7 ± 10.7 days. However, the mean ECLS run length in survivors was 4.3 ± 1.8 days and the longest ECLS run in a survivor was 7.25 days. Two of the 3 patients who died had very long run lengths (28.8 and 24.7 days, respectively), whereas 1 patient had a short run (2.4 days). Five of the 8 patients (63%), including all of the 3 who died, experienced a bleeding complication of some kind. Two patients required continuous venovenous hemofiltration, 1 of whom died and 1 of whom survived. Six patients underwent tracheostomy on ECLS, 1 patient already had undergone tracheostomy, and 1 patient did not undergo tracheostomy. CONCLUSIONS ECLS is useful in treating severe pancreatitis-induced ARDS. Pancreatic debridement can be performed during ECLS, using a comprehensive protocol to minimize bleeding complications.

Abstract
Acute pancreatitis represents a spectrum of disease, ranging from a mild, transitory illness to a severe, rapidly progressive hemorrhagic form, with massive necrosis and mortality rates of up to 24%. The reported incidence of acute pancreatitis diagnosed first at clinicopathologic autopsy ranges between 30% and 42%. To better describe outpatient fatalities due to acute pancreatitis that present as sudden, unexpected death, we retrospectively reviewed the autopsy files at the Institute of Legal Medicine, University of Hamburg, Germany, from 2000-2004. Individual cases were analyzed for sex, age, race, circumstances of death, social background of the deceased and previous medical history, seasonal occurrence of the disease, blood alcohol concentration at the time of death, body mass index, autopsy findings, histopathology, and etiology of acute pancreatitis. Among the 6178 autopsies carried out during the 5-year period evaluated, there were 27 cases of acute pancreatitis that presented as sudden, unexpected death. In all cases, the diagnosis was first made at autopsy. The male:female ratio was 1.7:1 and the mean age was 52 years (range, 30-91 years). Etiologies of acute pancreatitis included alcohol (n=19), gall stones (n=2), other identified etiologic factors (n=3), and idiopathic (n=3). Complications of acute pancreatitis included lung edema and/or acute respiratory distress syndrome, peritonitis, disseminated intravascular coagulation, and sepsis. At least 20 subjects (74%) had lived isolated, with no social contacts. Contrary to the clinical observations of a clear seasonal variation in the onset of acute pancreatitis, we found no correlation between death due to acute pancreatitis and a specific month or season. Many prior studies have suggested that the majority of deaths in severe acute pancreatitis occur in the late phase of the disease as a result of pancreatic sepsis. Conversely, in the present study, the majority of affected individuals died during the very early phase of the disease. While gallstones represent the main etiologic factor in most larger clinical series, biliary etiology seems to play only a minor role in outpatient deaths undergoing medicolegal autopsies. Data derived from medicolegal autopsy studies should be included in future population-based studies of acute pancreatitis.

Abstract
Acute pancreatitis in its severe form is complicated by multiple organ system dysfunction, most importantly by pulmonary complications which include hypoxia, acute respiratory distress syndrome, atelectasis, and pleural effusion. The pathogenesis of some of the above complications is attributed to the production of noxious cytokines. Clinically significant is the early onset of pleural effusion, which heralds a poor outcome of acute pancreatitis. The role of circulating trypsin, phospholipase A2, platelet activating factor, release of free fatty acids, chemoattractants such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, IL-6, IL-8, fMet-leu-phe (a bacterial wall product), nitric oxide, substance P, and macrophage inhibitor factor is currently studied. The hope is that future management of acute pancreatitis with a better understanding of the pathogenesis of lung injury will be directed against the production of noxious cytokines.

Abstract
OBJECTIVE We developed a new method to quantitate leukocyte accumulation in tissues and used it to examine the time course and severity of acute experimental pancreatitis. BACKGROUND Leukocyte activation and infiltration are believed to be critical steps in the progression from mild to severe pancreatitis and responsible for many of its systemic complications. METHODS Pancreatitis of graded severity was induced in Sprague-Dawley rats with a combination of caerulein and controlled intraductal infusion. Technetium-99m (99mTc)-labeled leukocytes were quantified in pancreas, lung, liver, spleen, and kidney and compared with myeloperoxidase activity. The severity of pancreatitis was ascertained by wet/dry weight ratio, plasma amylase, and trypsinogen activation peptide in the pancreas. The time course of leukocyte accumulation was determined over 24 hours. RESULTS Pancreatic leukocyte infiltration correlated well with tissue myeloperoxidase concentrations. In mild pancreatitis, leukocytes accumulated only in the pancreas. Moderate and severe pancreatitis were characterized by much greater leukocyte infiltration in the pancreas than in mild disease (p < 0.01), and increased 99mTc radioactivity was detectable in the lung as early as 3 hours. 99mTc radioactivity correlated directly with the three levels of pancreatitis. CONCLUSIONS Mild pancreatitis is characterized by low-level leukocyte activation and accumulation in the pancreas without recruitment of other organs; marked leukocyte accumulation was found in the pancreas and in the lung in more severe grades of pancreatitis. These findings provide a basis for the pathophysiologic production of cytokines and oxygen free radicals, which potentiate organ injury in severe pancreatitis. This study validates a new tool to study local and systemic effects of leukocytes in pancreatitis as well as new therapeutic hypotheses.

Abstract
Ascites and pleural and pericardial effusions can be observed during acute pancreatitis. The aims of this study were to evaluate their incidence, natural history, and prognostic role in patients with acute pancreatitis. One hundred patients consecutively admitted with a diagnosis of acute pancreatitis were prospectively submitted to abdominal, pleural, and cardiac ultrasonography at admission and during follow-up. Ascites was found in 18 patients, pleural effusion in 20, and pericardial effusion in 17. Twenty-four patients of this series had severe pancreatitis; three of them died. All effusions disappeared spontaneously in patients who survived pancreatitis up to two months after dismissal. At multivariate analysis ascites and pleural effusion were demonstrated to be accurate independent predictors of severity. The respective odds ratios were 5.9 [95% confidence interval (CI), 1.5-23.0%) and 8.6 (95% CI, 2.3-32.5%). Furthermore the presence of pleural effusion, ascites, and pericardial effusion were associated with an increased incidence of pseudocyst during follow-up. Ascites and pleural and pericardial effusions are frequent during acute pancreatitis. Pleural effusion and ascites are accurate predictors of severity in these patients.

Abstract
A 42-year-old man was admitted complaining of dyspnea. Chest X-ray showed an increase in cardiac size, and echocardiography revealed a large volume of pericardial effusion. Pancreatic enzyme levels were elevated in both serum and pericardial effusion. Computed tomography and endoscopic retrograde pancreatography demonstrated a fistula connecting a pancreatic pseudocyst with the pericardium and the right pleural cavity. Massive pericardial and right pleural effusion is an extremely rare complication of chronic pancreatitis. In this case, computed tomography and endoscopic retrograde pancreatography were useful for diagnosing the fistula.

Abstract
Severe necrotizing pancreatitis is accompanied by release of hemorrhagic ascites fluid (HAF), which is thought to be related to the occurrence and frequency of cardiocirculatory and pulmonary failure as a consequence of acute pancreatitis. The purpose of this study was to evaluate the role of HAF due to these systemic complications. Experiments were performed in 25 pigs (mean b.wt. 22 +/- 1 kg) under general anesthesia and mechanical ventilation. The animals received 50 ml/kg b.wt. i.p. of either physiologic saline solution (control CO, n = 9) or hemorrhagic ascites fluid (HAF, n = 16). HAF was obtained from 16 pigs with pancreatitis induced by intraductal infusion of bile salt. Eight animals in the HAF group were pretreated with indomethacin (10 mg/kg i.v. INDO/HAF). All animals were followed up for 6 h. Mean arterial pressure, cardiac output, and stroke volume fell significantly in the HAF (-25%, -27%, -27%) and in the INDO/HAF groups (-24%, -20%, -17%) as compared with controls (-6%, -6%, -6%). Also, left ventricular end-diastolic pressure (LVEDP) decreased by 52% and 48% in both HAF recipient groups, whereas LVEDP was unchanged in the control group. Myocardial contractility (Vmax) remained unaltered in all experimental groups. No significant differences in gas exchange and lung dry/wet weight ratio were observed. Lipase and PGI2 of the unpretreated HAF group rised to 203% and 198% in arterial blood at 6 h compared with unaltered levels in the control group. No increase of prostanoid concentrations was detected in the indomethacin-pretreated group, whereas lipase increase by a comparable extent as in the HAF group. We conclude that the early consequences of HAF are mainly characterized by systemic hypotension due to hypovolemia.

Abstract
Because of improved management of animals in intensive care facilities, veterinarians are often confronted with patients at risk of developing adult respiratory distress syndrome (ARDS). The four objectives of this review are: 1) to describe the clinical conditions which place animals at risk for development of ARDS, 2) to give the reader a comprehensive understanding of the pathophysiology of endotoxin-induced lung injury, 3) to address the interspecies variability in susceptibility to endotoxin-induced lung injury, and 4) to outline areas where veterinarians should be concentrating their diagnostic and therapeutic efforts with regards to this syndrome. Because there is little written in the veterinary literature on ARDS, this review will rely heavily on the human ARDS literature as well as on research in animal models of acute lung injury.

Abstract
Of 128 patients who underwent upper abdominal surgery, examined by standard preoperative and postoperative chest roentgenograms for the formation of postoperative pleural effusions, 89 had postoperative pleural effusions. Their presence was not related to the type of operation, infection, serum amylases, sex, smoking habits, or weight. There was no correlation between the localization of the pleural effusions and that of the abdominal incisions. There was a positive correlation between atelectasis and pleural effusion, but no evidence of a causal relationship. Pleural effusions might be related to postoperative sodium and water retention, and aggravated by an age-related relative cardiac decompensation. Early postoperative pleural effusions are common and do not require specific treatment.
