Legionnaires' disease is an atypical pneumonia caused by species are found in freshwater sources and are transmitted through inhalation of contaminated aerosols. Patients commonly present with fever, chills, and cough. However, in immunosuppressed patients or severe cases, the disease can lead to multiorgan failure. In recent years, the incidence of Legionnaires' disease has drastically increased and unfortunately is commonly underdiagnosed. Gold-standard diagnosis is made through sputum cultures; however, urine antigen remains the most common test used for diagnosis. Goal-directed care includes antibiotics and supportive care. This case highlights a rare and unique presentation of Legionnaires' disease presenting with an elevated 2:1 aspartate aminotransferase to alanine transaminase pattern, typically seen with alcoholic hepatitis.

BACKGROUND
Obstructive Jaundice (OJ) is a common clinical condition with potential outcomes, including hepatocyte necrosis, bile duct hyperplasia, significant cholestatic liver fibrosis, and, in severe cases, liver failure. Resveratrol (RES), a polyphenol present in grapes and berries, has demonstrated efficacy in improving OJ. However, the precise mechanism of its action remains unclear.
METHODS
In this study, we employed network pharmacology to investigate the underlying molecular mechanism of RES in the treatment of OJ. The targets of RES were identified using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), SuperPred, and SwissTargetPrediction database. The targets related to OJ were gathered from the DisGeNET, GeneCards, DrugBank, and Online Mendelian Inheritance in Man (OMIM) databases, and the intersection of these targets was determined using Venny2.1.0. Subsequently, an active component-target network was constructed using Cytoscape software. The Protein-Protein Interaction (PPI) network was generated using the String database and Cytoscape software. Following this, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted using the Bioconductor platform. Finally, quantitative Real-Time PCR (qRT-PCR), Western Blotting (WB), and Enzyme-Linked Immunosorbent Assay (ELISA) were employed to assess RNA and protein expression levels in related pathways.
RESULTS
The findings revealed a selection of 56 potential targets for RES, and a search through the online database identified 2,742 OJ-related targets with overlapping in 27 targets. In the PPI network, mTOR, CYP2C9, CYP1A1, CYP3A4, AHR, ESR1, and HSD17B1 emerged as core targets. KEGG analyses demonstrated that the primary pathways of RES in treating OJ, particularly those related to lipid metabolism, include linoleic acid metabolism, arachidonic acid metabolism, metabolism of xenobiotics by cytochrome P450, lipid and atherosclerosis, tyrosine metabolism, steroid hormone biosynthesis, and pentose and glucuronate interconversions signaling pathways. Furthermore, in vivo experiments indicated that RES significantly ameliorated liver injury induced by Common Bile Duct Ligation (CBDL) in rats with OJ. It lowered serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, reduced liver tissue MDA levels, increased glutathione (GSH) content, and enhanced activity of superoxide dismutase (SOD), alleviating liver damage. Metabolomics analysis revealed that the therapeutic effect of RES in OJ involved alterations in lipid metabolic pathways, hinting at the potential mechanism of RES in treating OJ. ELISA, qRTPCR, and WB analyses confirmed lower expression levels of mTOR, CYP1A1, and CYP2C9 in the RES group compared to the model group, validating their involvement in the lipid metabolism pathway.
CONCLUSION
In conclusion, RES exhibited a protective effect on liver function in rats with OJ. The underlying mechanism appears to be linked to antioxidant activity and modulation of lipid metabolism pathways.

INTRODUCTION
Bronchobiliary fistulas are rare and difficult to treat. Peacock first reported this entity in 1850 while treating a patient with hepatic encopresis.
CASE PRESENTATION
A 67-year-old Chinese male patient presented to the outpatient clinic with a complaint of coughing up phlegm with chest tightness for 4 days with symptoms of intermittent bilirubin sputum with a sputum volume of about 500 ml per day but no symptoms of abdominal pain or jaundice and no yellow urine or steatorrhea. The examination revealed cyanosis of the lips and mouth, barrel chest, low breath sounds on the right side, and a large number of wet rales heard in both lungs. The imaging investigations were suggestive of bronchobiliary fistula. Therefore, the patient was operated on and discharged with no perioperative complications.
CONCLUSION
Bronchobiliary fistula should be considered diagnostically in patients with known liver disease who also experience trauma or medical treatment and cough up bile-colored sputum, regardless of the presence of concurrent infections, and in conjunction with radiological expertise to identify it. Here, we report a case of bronchobiliary fistula and a brief review of the literature on it.

We describe the case of a 57-year-old male with jaundice, abdominal distension and fatigue. He was diagnosed as chronic active Epstein-Barr virus infection (CAEBV) due to intermittent elevated liver enzymes, hepatosplenomegaly and pancytopenia, with persistent positive of EBV biomarkers in blood and also positive in liver tissue. The patient was reinfected by SARS-CoV-2 within 2 months companied with CAEBV. The patient's second infection with SARS-CoV-2 led to the aggravated liver dysfunction with pneumonia and re-admission. After receiving symptomatic treatment, the patient showed significantly improvement of symptoms with partially restoration of liver function. After discharge, the patient's health status continued to deteriorate and eventually died. The instances of SARS-CoV-2 co-infection with the original chronic virus are not uncommon, but the exact mechanism of EBV and SARS-CoV-2 coinfection and the relationship between them are still unclear. Since co-infection of SARS-CoV-2 with original chronic virus might affect each other and lead disease aggravated and complicated, it is necessary to differentiate in the diagnosis of disease and it is important to be aware of the re-infection signs of SARS-CoV-2 in people with chronic virus infection diseases, as well as the risk of co-infection of SARS-CoV-2 with other viruses.

INTRODUCTION AND IMPORTANCE
Biliary atresia (BA) is characterized by the presence of persistent cholestatic jaundice during the neonatal period. This group of patients is at higher risk for liver disease and/or portal hypertension compared with other chronic liver diseases.
CASE PRESENTATION
We present a newborn patient who had biliary stools early postnatally, but her gallbladder was not seen on radiological examination and was referred to our clinic. On examination, polysplenia was seen, and the inferior vena cava was not seen. The patient's stool color changed to a creamy stool without bile three weeks postnatally. The neonate was diagnosed with biliary atresia and splenic malformation (BASM) syndrome. The patient underwent a Kasai portoenterostomy in the 3rd week of age and was preoperatively diagnosed with malrotation and treated with a Ladd procedure at the same time. The patient had a postoperative stool with bile and decreased bilirubinemia with a normal defecation period.
CLINICAL DISCUSSION
BASM syndrome, clinically has different causes and a worse prognosis than isolated BA. The syndrome can lead to end-stage cirrhosis and liver failure if left untreated. Although timely Kasai surgery is the standard treatment for BA, the age of the patient at the time of the surgery is different depending on BA groups.
CONCLUSION
The most important prognostic factors for BASM syndrome are early diagnosis and treatment. Despite this, the patients need careful follow-up. Postoperative adjuvant steroid therapy may have a good impact on the outcomes.

Surgery Jun 2024The optima preoperative biliary drainage before pancreaticoduodenectomy in patients with biliary tract and pancreatic cancer remains controversial.
Impact of biliary drainage method before pancreaticoduodenectomy on short- and long-term outcomes in patients with periampullary carcinoma and obstructive jaundice: A multicenter retrospective analysis.
BACKGROUND
The optima preoperative biliary drainage before pancreaticoduodenectomy in patients with biliary tract and pancreatic cancer remains controversial.
METHODS
A total of 898 patients who underwent preoperative biliary drainage via endoscopic retrograde biliary drainage, endoscopic transnasal biliary drainage, or percutaneous transhepatic biliary drainage before pancreaticoduodenectomy for biliary tract and pancreatic cancer were included. Perioperative and long-term outcomes were analyzed.
RESULTS
The Clavien-Dindo grade ≥3 morbidity rates after pancreaticoduodenectomy were higher in the endoscopic retrograde biliary drainage (21.9%; P = .001) or endoscopic transnasal biliary drainage (20.2%; P = .007) than in the percutaneous transhepatic biliary drainage (9.7%) groups. In biliary tract cancer, the frequency of dissemination after pancreaticoduodenectomy was higher in the percutaneous transhepatic biliary drainage (15.3%) than in the endoscopic retrograde biliary drainage (0.7%; P = .001) and endoscopic transnasal biliary drainage (4.1%; P = .037) groups; percutaneous transhepatic biliary drainage was an independent factor associated with worse disease-free survival (P = .04), whereas in pancreatic cancer the frequency of dissemination and survival was comparable among the 3 preoperative biliary drainage methods. Albumin <3.9 g/dL was independently associated with worse overall survival in patients with both pancreatic (P = .038) and biliary tract (P = .002) cancers, respectively. During biliary drainage, external drainage (P = .038) was independently associated with albumin <3.9 g/dL; albumin was higher in endoscopic retrograde biliary drainage group than in endoscopic transnasal biliary drainage or percutaneous transhepatic biliary drainage groups after 21 days from tube insertion.
CONCLUSION
In biliary tract cancer, percutaneous transhepatic biliary drainage may carry the risk of increasing the incidence of disseminative recurrence. In pancreatic cancer, percutaneous transhepatic biliary drainage is preferable owing to fewer complications without influencing recurrence. However, if patients cannot undergo surgery immediately, endoscopic retrograde biliary drainage will be applicable to help the preservation of nutritional status, which can have an impact on survival.

A case is presented of a 64-year-old male patient who was admitted because of delirium, jaundice, a pattern of cholestasis in the liver profile and a right lung mass in the context of a constitutional syndrome and weight loss in the last eight months. The lung mass was punctured and the culture of the obtained material developed white colonies, identified by mass spectrometry (MALDI-TOF) as Nocardia cyriacigeorgica. Regarding the clinical diagnosis, it was considered as systemic lupus erythematosus (SLE), on the basis of fulfilling 8 criteria according to SLICC 2012 group, and 24 points according to EULAR/ACR 2019. The liver biopsy showed a mixt cellular infiltrate in portal spaces, with absence of interphase hepatitis and presence of peripheral ductular reaction. These findings were interpreted as liver compromise relate to SLE. Delirium was also considered as a neurological manifestation related to SLE on the basis of ruling out other causes. After being treated with antibiotics and documenting a reduction in the size of the lung mass he received cyclophosphamide in intravenous pulses, achieving normalization of his liver profile and his state of consciousness, and a progressively weight recovering. A year after he was in good health. The report of this case is justified because of the rare presenting form of late onset SLE, as well as the concomitant pulmonary nocardiosis in the absence of previous immunosuppressant treatment.

BACKGROUND
Patients with pancreatic cancer and obstructive jaundice routinely undergo endoscopic stent placement (ES). It is well known that ES causes bacterial contamination and infectious complications after pancreatic resection.
OBJECTIVE
To compare short-term outcomes and survival in patients undergoing pancreatic head resection after preoperative ES vs preoperative surgical drainage (SD) via T-tube insertion.
METHODS
Patients with obstructive jaundice who underwent SD or ES from 2016 to 2022 were identified from a prospective database. Outcome analyses included microbiological bile contamination, overall morbidity and assessment of the overall complication burden using the Comprehensive Complication Index (CCI). Overall survival was investigated by Kaplan‒Meier analysis.
RESULTS
A total of 55 patients with SD were identified and matched with 110 ES patients. After the primary intervention, ES patients experienced more complications (ES: 17.3% vs. SD: 3.6%; P=0.013). The overall complication burden after pancreatic resection was higher in ES patients than in SD patients (CCI: 27.2 vs. 19.9; P=0.022). Additionally, bacterial contamination of the bile was more frequent in ES patients compared to SD individuals (94.3% vs. 7.1%; P<0.001) with similar bacteria in 83.3% of postoperative abdominal infections in ES patients. While overall survival did not differ between the two groups, patients with postinterventional complications after ES had an impaired survival compared to those without complications (11.3 mo vs. 20.4 mo; P=0.03).
CONCLUSION
SD for obstructive jaundice in resectable pancreatic cancer is associated with a lower overall complication burden. Additionally, patients with complications after ES experience worse overall survival. These findings indicate to rethink our standards of treatment of obstructive jaundice in patients with pancreatic cancer.

Review
Hydatid disease is caused by the tapeworm and is a zoonosis that endemically affects certain geographic areas with a high prevalence in animal husbandry. Due to globalization, the pathology can also be encountered beyond these preferred geographic areas. It predominantly affects the liver and lungs, with pancreatic localizations of hydatid cysts being rare and posing a challenge for differential diagnosis and surgical tactics. The present study aimed to provide a recent scoping of the literature on this type of localization, analyzing demographic data, therapeutic management, and postoperative outcomes. It was observed that females are more frequently affected in pancreatic hydatid localizations (p < 0.001), with the most common symptomatology represented by abdominal pain. The preferred localization was at the level of the pancreatic tail (32.5%), followed by cephalic localizations (25%). The preferred surgical approach was open surgery, with an observed preference for open surgery in specific localizations, such as the head, isthmus, and body of the pancreas (p < 0.001). Radical procedures are more commonly used than conservative ones (52.5% vs. 47.5%), and paradoxically, although less invasive, procedures such as inactivation and drainage are associated with more frequent complications (p = 0.03). This type of localization, due to the elements of local anatomical topography, requires adequate preparation in biliopancreatic surgery, considering that sometimes preoperative diagnosis is not oriented, and intraoperative records may require extensive interventions. Our research encompassed a thorough review of literature spanning the last decade using PubMed and Google Scholar databases, focusing specifically on cases involving primary hydatid cysts found within the pancreas. Thirty-three relevant articles were published between 2014 and 2024. In addition, we presented a unique case study that illustrates this uncommon occurrence.

OBJECTIVES
To evaluate the usefulness of porta hepatis lymph nodes (PHLNs) on ultrasonography (US) scans in diagnosing biliary atresia (BA) and predicting the outcomes after Kasai portoenterostomy (KPE) surgery.
METHODS
A total of 668 patients from one hospital were enrolled in the study (542 non-BA and 126 BA). The independent and combined diagnostic efficacy of PHLNs, triangular cord (TC) thickness, and gallbladder morphology were assessed by drawing the receiver operating characteristic (ROC) curves and counting the area under the ROC curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The US features, histopathological findings of PHLNs, and serum total bilirubin (TBIL) levels 3 months post-KPE were correlated.
RESULTS
The AUC, sensitivity, specificity, PPV, and NPV of PHLNs with hyperechogenicity and a maximum length larger than 8.4 mm were 0.898, 81.8%, 97.8%, 89.6%, and 95.8%, respectively. The combination of PHLNs, TC thickness, and gallbladder morphology achieved the best overall diagnostic efficacy among all indicators with an AUC of 0.927 and a sensitivity of 99.2%. The germinal center number and bile particle number of PHLNs were positively correlated with pathological size and US echogenicity intensity of PHLNs, respectively (r = 0.591, 0.377, p = 0.001, 0.004). The pathological size of PHLNs in BA patients was negatively correlated with jaundice clearance status 3 months after KPE surgery (r = -0.385, p = 0.047).
CONCLUSION
PHLNs with hyperechogenicity and a maximum length > 8.4 mm are useful US indicators for BA diagnosis. Additionally, the enlargement of PHLNs might play a role in predicting outcomes of KPE surgery.
CRITICAL RELEVANCE STATEMENT
The article proposed for the first time that PHLNs with hyperechogenicity and a maximum length > 8.4 mm are a useful US indicator for diagnosing BA.
KEY POINTS
PHLNs may be helpful in diagnosing BA and predicting outcomes after surgery. Enlarged hyperechoic PHLNs are a useful diagnostic indicator for BA, and play a role in predicting surgical outcomes. These findings can assist clinicians in more accurately diagnosing BA, enabling more timely treatments.
