Study on the Correlation Between the Expression of NF-Ƙb in the Alveolar Lavage Fluid of Children with Severe Mycoplasma Pneumoniae Pneumonia, Its Clinical Characteristics, and Cellular Immunity.
OBJECTIVE
This study explored the level of nuclear factor-ƙB (NF-ƙB) in the bronchoalveolar lavage fluid (BALF) of children with severe Mycoplasma Pneumoniae pneumonia (SMPP) and the correlation between NF-ƙB, cellular immunity, and clinical characteristics.
METHODS
A total of 41 hospitalized children diagnosed with SMPP were selected and included in the SMPP group, and 13 bronchial foreign bodies (FB) without infection during the same period were included in the FB group. The NF-ƙB in the BALF of participants was detected by enzyme-linked immunosorbent assay. The correlation between NF-ƙB and laboratory findings, cellular immunity, and the clinical features in children with SMPP was analyzed. The differences in chest imaging and bronchoscopy in children with SMPP were observed.
RESULTS
The levels of NF-ƙB were significantly increased in the SMPP group compared with the FB group (P < 0.001). There were correlations between different NF-ƙB pairs in the SMPP group (P < 0.01). Nuclear factor-ƙB (NF-ƙB) correlated with IL-6, the mycoplasma load in BALF, fever peak, length of hospital stay, and sputum suppository (P < 0.05). The higher the intracellular NF-ƙB level in BALF, the lower the CD3+ CD4+ value in peripheral blood (P < 0.05). Intracellular NF-ƙB and total NF-ƙB correlated with pleural effusion, pericardial effusion, and extrapulmonary complications (P < 0.05).
CONCLUSION
NF-ƙB is involved in airway inflammation changes in children with SMPP. The higher the level of NF-ƙB in the airway, the more severe the clinical manifestations, and the longer the length of hospital stay is likely to be.

Malakoplakia is a rare granulomatous, chronic inflammatory disease generally affecting the urogenital organs, though it can arise in other organs. The clinical manifestations of malakoplakia vary depending on the affected organ. The final diagnosis is confirmed by the presence of Michaelis-Gutmann bodies on pathology. This report describes a case of pelvic malakoplakia accompanied by an ovarian tumour-cutaneous fistula, initially misdiagnosed as advanced ovarian cancer invading the anterior abdominal wall with left pleural effusion based on imaging studies and increased serum carbohydrate antigen 19-9. The patient underwent left thoracentesis and fluid collection from the fistula tract for cytology, which showed no malignancy. She underwent primary debulking surgery, including removal of the fistula tract from anterior abdominal wall. Histopathological examination revealed malakoplakia coexisting with mucinous cystadenoma of the left ovary. For postoperative management, she received prolonged oral antibiotics for 6 months. There was no evidence of disease recurrence at the 24-month follow-up.

A 79-year-old man found to have a pulmonary nodule and pleural effusion on CT went on to have an 18F-FDG PET/CT scan. The lung abnormality did not show FDG uptake and appeared benign. However, PET/CT detected moderately increased FDG uptake associated with a left atrial appendage closure device inserted 11 months prior to the PET/CT. Infection of a left atrial closure device has previously been demonstrated with FDG PET/CT. This case, in the absence of infection, with normal serum inflammatory markers, highlights that left atrial closure devices, in common with other foreign bodies/devices, may demonstrate significant, incidental FDG uptake.

BACKGROUND
Percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) provides an effective alternative procedure for the management of complex hepatolithiasis and choledocholithiasis. Enhanced recovery after surgery (ERAS) program is an evidence-based approach that was developed to reduce surgical stress and accelerate postoperative recovery. However, little is known regarding PTCSL in the context of ERAS. The aim of this study was to evaluate the efficacy and safety of PTCSL within ERAS programs.
PATIENT AND METHODS
The clinical data of patients who underwent PTCSL within ERAS programs consulted at our hospital between November 2017 and November 2022 was retrospectively reviewed. Individualized perioperative ERAS items were evaluated for all patients. The demographics, intraoperative variables, and postoperative outcomes were analyzed.
RESULTS
A total of 43 patients who underwent PTCSL were included in the study. There were 13 men and 30 women aged between 39 and 89 years with an average age of 60 years (60.49 ± 12.37). The stone clearance rate was 77 % after the first operation, and the final clearance rate was 95 %. The incidence of complications in this study is 18.6 % (8/43), including 6 patients with Clavien-Dindo I-II, and 2 patients with Clavien-Dindo III. Pleural effusion, abdominal effusion, infection, bile leakage, and biliary bleeding are the most common complications, however, all patients recovered after aggressive treatment.
CONCLUSION
PTCSL is a relatively safe, feasible, and efficient method for treating complex hepatolithiasis and choledocholithiasis within ERAS programs. Individualized ERAS entries and precise disease management are required to minimize the occurrence of complications and to provide effective treatment.

We report a patient with fever and cough for 2 months who was finally given a diagnosis of alveolar-pleural fistula due to aspergillus empyema. We successfully closed the alveolar-pleural fistula with a ventricular septal defect occluder through bronchoscopy. Endoscopic closure of an alveolar-pleural fistula with ventricular septal defect occluder is worth being explored.

A multicenter retrospective analysis of conventionally collected data. To identify the potential causes of hypoproteinemia after traumatic spinal cord injury (TSCI) and provide a diagnostic model for predicting an individual likelihood of developing hypoproteinemia. Hypoproteinemia is a complication of spinal cord injury (SCI), an independent risk factor for respiratory failure in elderly patients with SCI, and a predictor of outcomes in patients with cervical SCI. Few nomogram-based studies have used clinical indicators to predict the likelihood of hypoproteinemia following TSCI. This multicenter retrospective clinical analysis included patients with TSCI admitted to the First Affiliated Hospital of Guangxi Medical University, Wuzhou GongRen Hospital, and Dahua Yao Autonomous County People Hospital between 2016 and 2020. The data of patients from the First Affiliated Hospital of Guangxi Medical University were used as the training set, and those from the other 2 hospitals were used as the validation set. All patient histories, diagnostic procedures, and imaging findings were recorded. To predict whether patients with TSCI may develop hypoproteinemia, a least absolute shrinkage and selection operator regression analysis was conducted to create a nomogram. The model was validated by analyzing the consequences using decision curve analysis, calibration curves, the C-index, and receiver operating characteristic curves. After excluding patients with missing data, 534 patients were included in this study. Male/female sex, age ≥ 60 years, cervical SCI, pneumonia, pleural effusion, urinary tract infection (UTI), hyponatremia, fever, hypotension, and tracheostomy were identified as independent risk factors of hypoalbuminemia. A simple and easy-to-replicate clinical prediction nomogram was constructed using these factors. The area under the curve was 0.728 in the training set and 0.881 in the validation set. The predictive power of the nomogram was satisfactory. Hypoalbuminemia after TSCI may be predicted using the risk factors of male/female sex, age ≥ 60 years, cervical SCI, pneumonia, pleural effusion, UTI, hyponatremia, fever, hypotension, and tracheostomy.

To analyze the characteristics of as well as macrolide antibiotic resistance through whole-genome sequencing and comparative genomics. Thirteen clinical strains isolated from 2003 to 2019 were selected, 10 of which were resistant to erythromycin (MIC >64 µg/mL), including 8 P1-type I and 2 P1-type II. Three were sensitive (<1 µg/mL) and P1-type II. One resistant strain had an A→G point mutation at position 2064 in region V of the 23S rRNA, the others had it at position 2063, while the three sensitive strains had no mutation here. Genome assembly and comparative genome analysis revealed a high level of genome consistency within the P1 type, and the primary differences in genome sequences concentrated in the region encoding the P1 protein. In P1-type II strains, three specific gene mutations were identified: C162A and A430G in L4 gene and T1112G mutation in the CARDS gene. Clinical information showed seven cases were diagnosed with severe pneumonia, all of which were infected with drug-resistant strains. Notably, BS610A4 and CYM219A1 exhibited a gene multi-copy phenomenon and shared a conserved functional domain with the DUF31 protein family. Clinically, the patients had severe refractory pneumonia, with pleural effusion, necessitating treatment with glucocorticoids and bronchoalveolar lavage. The primary variations between strains occur among different P1-types, while there is a high level of genomic consistency within P1-types. Three mutation loci associated with specific types were identified, and no specific genetic alterations directly related to clinical presentation were observed.IMPORTANCE is an important pathogen of community-acquired pneumonia, and macrolide resistance brings difficulties to clinical treatment.

Congenital chylothorax is the most common form of pleural effusion during the neonatal period; however, no treatment strategy exists. The pathogenesis and etiology of this disease are not fully understood; hence, several cases are difficult to treat. Some patients with chylothorax may not survive due to severe respiratory distress. Prednisolone (PSL) is sometimes used to treat congenital chylothorax but is rarely used in the early postnatal period. In this report, we describe a neonate with prenatal pleural effusion who was successfully treated with PSL from day one after requiring endotracheal intubation and ventilator management due to a postnatal diagnosis of chylothorax. The patient was extubated at four days of age, weaned from the ventilator at 10 days of age, and discharged home at 40 days of age after a total of 10 days of administration. Although the mechanism of action of PSL in chylothorax is unknown, and because it is a steroid, side effects such as gastrointestinal perforation and susceptibility to infection should be noted. The present case suggests the utility of early PSL administration for the treatment strategy of congenital chylothorax.

Introduction Dengue fever, caused by the dengue virus transmitted by Aedes aegypti mosquitoes, is a significant public health concern globally. Its resurgence in recent years, particularly in low- and middle-income countries, has led to increased morbidity and mortality rates. Atypical manifestations, involving the cardiac, liver, gut, renal, blood, bone, nervous, and respiratory systems, in dengue, can complicate both diagnosis and management. This study aimed to investigate the incidence of lung manifestations in dengue-infected individuals and their correlation with patient outcomes. Background The prevalence of dengue fever has risen dramatically over the past two decades, with Asia bearing the brunt of the burden, particularly India. The pathophysiology of lung complications in dengue remains unclear but is thought to be related to capillary leak syndrome and thrombocytopenia. Studies suggest that respiratory symptoms may be associated with severe cases and increased mortality rates. Despite limited research in India, understanding lung manifestations in dengue is crucial for improving diagnostic accuracy and patient care. Methods A retrospective study was conducted at K.S. Hegde Hospital, a tertiary care facility located in Mangalore, India, involving patients aged 18 years and above diagnosed with dengue fever between January and December 2019. Data gathered comprised patient demographics, clinical symptoms, laboratory findings, imaging results including radiographs, computed tomography (CT) scans of the chest (if accessible), ultrasound examinations of the chest and abdomen, and 2D echocardiograms, as well as patient outcomes. Diagnosis of lung manifestation was established through clinical assessment, chest X-ray interpretation, and ultrasound of the chest. Statistical analysis was conducted using SPSS Statistics (version 20), with a significance set at p<0.05. Results Out of 255 dengue cases, 10.19% (n=26) exhibited pulmonary manifestations, with pleural effusion being the most common. Older age (>50 years) and comorbidities were associated with a higher incidence of lung involvement. Respiratory symptoms, such as breathlessness, were more prevalent in patients with pulmonary complications. Laboratory parameters indicated distinct profiles in patients with lung manifestations, including elevated total count, urea, bilirubin, and liver enzymes, and reduced platelet counts. Mortality rates were higher in patients with lung involvement, older age, and comorbidities. Discussion The study findings highlight the importance of recognizing respiratory symptoms in dengue fever, particularly in older patients and those with underlying health conditions. The association between pulmonary involvement and adverse outcomes underscores the need for early detection and appropriate management strategies. Future research should focus on elucidating the pathophysiology of lung complications in dengue and developing targeted interventions to improve patient outcomes. Conclusion Lung manifestations in dengue fever represent a significant clinical challenge and are associated with increased morbidity and mortality. Early recognition of respiratory symptoms, along with prompt diagnostic evaluation and appropriate management, is essential for improving patient prognosis. Further studies are warranted to deepen our understanding of lung involvement in dengue and optimize therapeutic approaches to mitigate its impact on patient outcomes.

BACKGROUND
Thymic mucosa-associated lymphoid tissue (MALT) lymphoma is rare and is known to be associated with Sjögren's syndrome (SjS). SjS is rarely accompanied by serositis. Here, we describe the first case of postoperative cardiac tamponade and acute pleuritis in a patient with thymic MALT lymphoma associated with SjS.
CASE PRESENTATION
A 33-year-old woman with SjS presented with an anterior mediastinal mass on chest computed tomography, which was performed for further examination of the condition. Suspecting a thymic MALT lymphoma or thymic epithelial tumor, total thymectomy was performed. The mediastinal mass was histopathologically diagnosed as a thymic MALT lymphoma. The patient was discharged with a good postoperative course but visited the hospital 30 days after surgery for dyspnea. Cardiac tamponade was observed and drainage was performed. Four days after pericardial drainage, chest radiography revealed massive left pleural effusion, and thoracic drainage was performed. The patient was diagnosed with serositis associated with SjS and treated with methylprednisolone, which relieved cardiac tamponade and pleuritis.
CONCLUSIONS
Surgical invasion of thymic MALT lymphomas associated with SjS may cause serositis. Postoperative follow-up should be conducted, considering the possibility of cardiac tamponade or acute pleuritis due to serositis as postoperative complications.
