Lemierre syndrome with pulmonary empyema caused by Prevotella intermedia.

Lemierre syndrome is a rare disease that is most often caused by Fusobacterium necrophorum We present a case caused by Prevotella intermedia in a young, healthy man, complicated by multiple cavitary lung lesions, loculated pleural effusions requiring chest tube placement and trapezius abscess. Our case highlights (a) P. intermedia as a rare cause of Lemierre syndrome and (b) clinical response to appropriate antimicrobial therapy may be protracted.

Analysis of risk factors leading to multiple breast abscesses during lactation.

We investigated 1805 cases of breast abscesses during lactation to estimate the risk factors for multiple breast abscesses during lactation. A total of 2000 cases of breast abscesses during lactation were investigated using an online questionnaire, and 1805 cases with complete data were analyzed. The survey response rate was 90%. According to the number of abscesses, the patients were divided into 2 groups: single breast abscess (number = 1298) and multiple breast abscess (number = 507). Pearson chi-square test was used to compare the 15 risk factors between the 2 groups. Risk factors with significant differences were substituted into a binary logistic regression model to analyze the independent risk factors associated with multiple breast abscesses during lactation. There were significant differences between the 2 groups in (1) weeks postpartum, (2) separated from the baby, (3) breastfeeding exclusivity, (4) nipple inversion, (5) fever, (6) breast redness/swelling, (7) nipple pain, (8) breast massage by nonmedical staff, with (1), (5), (6), and (8) being independent risk factors. Patients under 6 weeks postpartum, separated from the baby, not exclusively breastfeeding, having an inverted nipple on the affected side, fever, breast skin redness and swelling on the affected side, nipple pain, and having undergone a breast massage by nonmedical staff are more likely to develop multiple breast abscesses.

Empyema caused by Actinomyces odontolyticus: A case report.

RATIONALE: Actinomyces odontolyticus causes a rare, chronic granulomatous infection that is frequently associated with immunocompromised states. A odontolyticus can cause infection in multiple organs, but empyema is rare. PATIENT CONCERNS: We report a case of empyema caused by A odontolyticus. The patient was a 64-year-old man. He was admitted to the hospital with a 5-day history of fever and dyspnea. He had caries and sequelae of cerebral apoplexy. DIAGNOSES: Metagenome next generation sequencing of pleural effusion was positive for A odontolyticus. Pathogen was identified by biphasic culture of pleural effusion fluid. INTERVENTIONS: According to the drug sensitivity test, linezolid 0.6 g twice daily and clindamycin 0.6 g 3 times a day were administered intravenously. Thoracic drainage was initially performed, but the drainage was not sufficient. Medical thoracoscopy was performed to fully drain the pleural effusion. OUTCOMES: After anti-infection and medical thoracoscopic therapy, the symptoms of this patient improved. LESSONS: Microbial metagenome sequencing can find pathogens that are difficult to culture by traditional methods. Adequate drainage was the key to the treatment of empyema. Medical thoracoscopy was recommended to remove the pleural effusion and spoilage when thoracic drainage is difficult. The common clinical features of A odontolyticus include a mass or swelling, abdominal disease, dental disease, and subcutaneous abscesses. Microbial metagenome sequencing can find pathogens that are difficult to culture by traditional methods. Adequate drainage was the key to the treatment of empyema. Medical thoracoscopy was recommended to remove the pleural effusion and spoilage when thoracic drainage is difficult.

Thoracic empyema: aetiology, diagnosis, treatment, and prevention.

PURPOSE OF REVIEW: The aim of this study was to review current key points in the aetiology, diagnosis, treatment, and prevention of empyema thoracis. Early postpandemic trends have seen an increasing global incidence and evolution in the aetiology of empyema. Due to varied aetiology and typically lengthy treatment, empyema will be disproportionately affected by the rising tide of antimicrobial resistance (AMR), thus warranting attention and further research. RECENT FINDINGS: Multiple novel biomarkers (e.g. IL-36γ) are under investigation to aid diagnosis, while oral health assessment tools are now available for prognosticating and risk-stratifying patients with thoracic empyema. There exists an ongoing lack of evidence-based guidance surrounding antibiotic treatment duration, surgical intervention indication, and prognostic scoring utility. SUMMARY: Understanding aetiologies in different global regions and settings is pivotal for guiding empirical treatment. Antimicrobial resistance will make thoracic empyema increasingly challenging to treat and should prompt increased awareness of prescribing practices. Novel biomarkers are under investigation which may speed up differentiation of pleural effusion types, allowing faster cohorting of patients.Although newly identified predictors of morbidity and mortality have been suggested to be beneficial for incorporation into clinical practice, further work is required to prognosticate, risk-stratify, and standardize treatment.

Empyema Secondary to Pneumonia: Whom Should We Operate?

Introduction: Empyema secondary to pneumonia is a common condition. A significant number of patients will require surgical intervention for drainage and decortication. The aim of this study was to identify predictive factors for surgical intervention. Materials and Methods: The medical records of patients who were diagnosed with empyema secondary to pneumonia between the years 2010 and 2019 in a university hospital were included in the study. Patients who underwent surgical intervention were defined as group A and nonoperative treatment as group B. Clinical and laboratory data were collected from medical records and patients' chest computerized tomography (CT) scans were reviewed. Results: A total of 194 patients were included in the study-86 patients were included in group A and 108 patients in group B. Several parameters on admission were found to have a statistically significant correlation with surgical intervention: younger age, higher systolic blood pressure, and elevated white blood count. Multivariant analysis showed that younger age was found to have a statistically significant correlation with operative intervention (adjusted odds ratio = 0.971, P = .023). A statistically significant correlation between surgical intervention and survival (adjusted hazard ratio [HR] = 1.762, P = .046) and an inverse correlation between age and survival (adjusted HR = 0.050, P < .001) were found. Surgical intervention was associated with increased survival irrespective of age. A total of 42 CT scans were available for review. The mean density of the empyema fluid in group A was higher by 4.3 hounsfield units compared to group B (P < .067). Conclusions: Younger age was found to be associated with surgical intervention among patients suffering from empyema secondary to pneumonia. Surgical intervention was associated with increased long-term survival, irrespective of patients' age. Several radiologic characteristics were associated with the need for surgery in this study: empyema fluid density, pleural thickening, and fluid loculations. Additional prospective studies are required to ascertain these results.

Prognostic Factors for Discharge Directly Home in Patients With Thoracoscopic Surgery for Empyema: A Multicenter Retrospective Cohort Study.

Background: Video-assisted thoracoscopic surgery is a widely recommended treatment for empyema in advanced stages. However, only a few studies have evaluated prognostic factors among patients with empyema who underwent video-assisted thoracoscopic surgery. Furthermore, no studies have evaluated predictors of direct discharge home. Patients and Methods: This multicenter retrospective cohort study included 161 patients with empyema who underwent video-assisted thoracoscopic surgery in five acute-care hospitals. The primary outcome was the probability of direct discharge home. The secondary outcome was the length of hospital stay after surgery. We broadly assessed pre-operative factors and performed univariable logistic regression for the direct discharge home and univariable gamma regression for the length of hospital stay after surgery. Results: Of the 161 included patients, 74.5% were directly discharged home. Age (>70 years; -24.3%); altered mental status (-33.4%); blood urea nitrogen (>22.4 mg/dL; -19.4%); and pleural pH (<7.2; -17.6%) were associated with high probabilities of not being directly discharged home. Fever (15.2%) and albumin (> 2.7 g/dL; 20.2%) were associated with high probabilities of being directly discharged home. The median length of stay after surgery was 19 days. Age (>70 years; 6.2 days); altered mental status (5.6 days); purulence (2.7 days); pleural thickness (>2 cm; 5.1 days); bronchial fistula (14.6 days); albumin (>2.7 g/dL; 3.1 days); and C-reactive protein (>20 mg/dL; 3.6 days) were associated with a longer post-operation hospital stay. Conclusions: Physicians should consider using these prognostic factors to predict non-direct discharge to the home for patients with empyema.

Case 322: Pyothorax-associated Lymphoma.

HISTORY: An 81-year-old man living in South Korea was referred to the pulmonology clinic because of abnormal findings at routine surveillance CT. His past medical history included right radical nephroureterectomy for ureteral cancer in 2016, transurethral resection of a bladder tumor in 2015, and tuberculous pleurisy in his third decade of life that was complicated by a chronic calcified empyema. He had been doing well clinically until 6 months prior, when he presented to an outside hospital with progressive right-sided chest pain and dyspnea and was found to have active tuberculosis. During that hospitalization, he underwent chest CT and CT-guided biopsy of an incidentally found thoracic lesion, which revealed chronic active inflammation. His symptoms improved after initiation of antituberculous medication, and he was discharged home to complete treatment. Because of interval growth of this lesion noted on a subsequent surveillance CT scan, he was referred to pulmonology for further evaluation. Laboratory tests obtained during his visit revealed mild leukocytosis (1258 cells × 109/L; normal range, 4000-10 000 cells × 109/L) with neutrophilic predominance (82% neutrophils; normal range, 50%-75% neutrophils), and a mildly elevated C-reactive protein level (3.17 mg/dL; normal range, 0-0.5 mg/dL). A sputum culture was negative for tuberculosis. The patient reported mild chest discomfort and dyspnea. Liver MRI was performed to further evaluate an abnormal lesion seen at CT. Given the patient's recent nonspecific biopsy results and tuberculosis treatment, no further work-up was pursued. Contrast-enhanced chest CT was performed 6 months later because the patient developed worsening chest pain and dyspnea. He remained afebrile, with persistent leukocytosis (1485 cells × 109/L) and an elevated C-reactive protein level (3.56 mg/dL). On the basis of the imaging findings, repeat CT-guided biopsy and PET/CT were performed, thereby enabling confirmation of the diagnosis, and appropriate treatment was initiated.

Intrathoracic Transposition of a Pedicled Latissimus Dorsi Muscle Flap for Complicated Chronic Empyema Thoracis: A Plea for its Popularity in our Subregion.

INTRODUCTION: Empyema thoracis is a debilitating disease that still constitutes a significant burden among thoracic surgical diseases in our environment. It sometimes occurs secondary to ruptured lung abscess with varying degrees of lung destruction and bronchopleural fistula. CASE REPORT: A 65-year-old woman presented to our unit with a two-month history of cough which subsequently became productive of purulent sputum and posture-dependent, and fever, with progressive dyspnea on exertion. She was subsequently managed for chronic right empyema thoracis secondary to a ruptured lung abscess. We briefly describe the evaluation, indication, and technique for intrathoracic transposition of a pedicled latissimus dorsi muscle flap for operative management of this index disease, and the very good medium and long-term outcomes observed for this patient. CONCLUSION: Where indicated and with meticulous preoperative planning, transposition of a pedicled latissimus dorsi muscle flap for complicated chronic empyema thoracis can prevent a surgical albatross with a reduced hospital stay, cost of treatment and excellent patient satisfaction at the meagre expense of about 30 minutes or less extra intra-operative time.

INTRODUCTION: L'empyème thoracique est une maladie invalidante qui constitue toujours un fardeau significatif parmi les maladies chirurgicales thoraciques dans notre environnement. Il survient parfois secondairement à un abcès pulmonaire rompu avec des degrés variables de destruction pulmonaire et de fistule bronchopleurale. RAPPORT DE CAS: Une femme de 65 ans s'est présentée à notre unité avec une toux persistante depuis deux mois, qui est ensuite devenue productive de crachats purulents dépendant de la posture, ainsi que de la fièvre, avec une dyspnée progressive à l'effort. Elle a ensuite été traitée pour un empyème thoracique chronique droit secondaire à un abcès pulmonaire rompu. Nous décrivons brièvement l'évaluation, les indications et la technique de transposition intrathoracique d'un lambeau musculaire grand dorsal pédiéculé pour la prise en charge opératoire de cette maladie, ainsi que les très bons résultats à moyen et long terme observés pour cette patiente. CONCLUSION: Lorsque cela est indiqué et avec une planification préopératoire méticuleuse, la transposition d'un lambeau musculaire grand dorsal pédiéculé pour un empyème thoracique chronique compliqué peut éviter un fardeau chirurgical avec une réduction du séjour hospitalier, du coût du traitement et une excellente satisfaction du patient, avec un faible coût supplémentaire en temps opératoire de seulement environ 30 minutes ou moins. MOTS-CLÉS: Abcès pulmonaire, lambeau musculaire grand dorsal pédiéculé, empyème thoracique, résultats.

A Case of Thoracic Empyema Caused by Actinomyces naeslundii.

BACKGROUND Actinomycosis is a clinically significant but uncommon infectious disease caused by anaerobic commensals of Actinomyces species, and the incidence of thoracic empyema is rare. We report an extremely rare case of empyema caused by Actinomyces naeslundii (A. naeslundii). CASE REPORT A 39-year-old man presented to our hospital with fever and dyspnea. He had massive pleural effusion and was diagnosed with a left lower-lobe abscess and left thoracic empyema. Thoracic drainage was performed and Ampicillin/Sulbactam was administered for 3 weeks. Four years later, the patient presented with back pain, and chest X-ray showed increased left pleural effusion. After close examination, malignant pleural mesothelioma was suspected, and computed tomography-guided needle biopsy was performed, which yielded a viscous purulent pleural effusion with numerous greenish-yellow sulfur granules. A. naeslundii was identified through anaerobic culture. Thoracoscopic surgery of the empyema cavity was conducted, and Ampicillin/Sulbactam followed by Amoxicillin/Clavulanate was administered for approximately 6 months. No recurrence has been observed for 1 year since the surgical procedure. CONCLUSIONS Actinomyces empyema is a rare condition, and this case is the second reported occurrence of empyema caused by A. naeslundii. The visual identification of sulfur granules contributed to the diagnosis. Long-term antibiotic therapy plays a crucial role in treatment.

Causes, management and treatment of empyema.

Infections in the pleural space have been a significant problem since ancient times and continue to be so today, with an incidence of 52% in patients with post-pneumonia syndrome. Typically, these effusions require a combination of medical treatment and surgical drainage, including debridement and decortication. Researchers have been studying the use of intrapleural fibrinolytics in managing complicated pleural effusions and empyema, but there is still ongoing debate and controversy among clinicians. Empyema has traditionally been considered a surgical disease, with antibiotics and chest tube drainage being the initial treatment modality. However, with advances in minimally invasive procedures such as video-assisted thoracoscopic surgery (VATS) and the use of intrapleural fibrinolytics, medical management is now preferred over surgery for many cases of empyema. Surgical options, such as open thoracotomy, are reserved for patients who fail conservative management and have complicated or chronic empyema. This comprehensive review aims to explore the evolution of various management strategies for pleural space infections from ancient times to the present day and how the shift from treating empyema as a surgical condition to a medical disease continues.

Salvage treatment of acute respiratory failure after autogenous tissue flap transplantation for chronic empyema with chest wall sinus: a case report and literature review.

BACKGROUND: Chronic empyema with chest wall sinus is a difficult and complex disease caused by multiple causative factors. It is difficult to control local infection due to its possible combination of bronchopleural fistula (BPF) and residual bone.The relevant literature emphasizes some risk factors for empyema progression after pneumonectomy, while the correlation between empyema and BPF after pneumonectomy increases mortality by infecting the remaining lungs. After pneumonectomy, the lung function of the contralateral side is particularly important. CASE PRESENTATION: This paper reports a 62-year-old male patient who underwent right pneumonectomy for squamous cell carcinoma of the lung 12 years ago and began to develop empyema with anterior chest wall sinus 3 years ago. After admission, chest computed tomography (CT) showed right pleural effusion and formation of chest wall sinus. According to his clinical symptoms and imaging examination, he was diagnosed as chronic empyema with chest wall sinus.Due to the huge residual cavity of the patient,the clinical effect of using free vastus lateralis myocutaneous flap combined with pedicled pectoralis major muscle flap to fill the abscess cavity was satisfactory,but acute respiratory failure occurred due to left lung aspiration pneumonia after operation. CONCLUSIONS: After a series of treatment measures such as tracheal cannula, tracheotomy, anti-infection, maintenance of circulatory stability, and rehabilitation training, the patient was ultimately rescued and cured. Postoperative follow-up showed that the muscle flaps survived and empyema was eliminated.

Empyema caused by Streptococcus constellatus in a patient infected with HIV: a case report and literature review.

BACKGROUND: Empyema caused by Streptococcus constellatus (S. constellatus) is rare in patients with HIV. To analyze the clinical data of a patient living with HIV (PLHIV), who got empyema caused by S. constellatus, investigating the diagnosis and treatment of this disease through literature review to improve the clinical understanding of this disease. CASE PRESENTATION: We have reported here a 58-year-old male PLHIV with cough, wheezing, and fever for 20 days. He has a history type 2 diabetes, alcohol abuse, and a teeth extracted. Chest computed tomography revealed multiple encapsulated pleural effusions, pneumatosis, and partial compressive atelectasis in the right lung. Submission of pleural efusions timely, and then cultures revealed S. constellatus. After comprehensive treatment, including antibiotics, closed pleural drainage, and intrapleural injection of urokinase, the pleural efusion was absorbed, and chest computed tomography also confirmed the improvement. CONCLUSIONS: S. constellatus should not be neglected as a pus pathogen in patients with HIV. comprehensive treatment is important for empyema of S. constellatus.

Rapid detection of S. pyogenes and S. pneumoniae in pleural fluid for diagnosis of parapneumonic empyema.

The aim of this study was to assess the reliability of rapid antigen detection tests (RADT) for Streptococcus pyogenes (GAS) and Streptococcus pneumoniae on pleural fluid samples for diagnosis of parapneumonic effusion/empyema (PPE) and their potential for improving pathogen identification rates. Sixty-three pleural samples were included from 54 patients on which GAS and S. pneumoniae RADT (BinaxNOW), culture, 16S rRNA PCR, and S. pneumoniae-specific PCR were performed. GAS RADT showed a sensitivity of 95.2% and a specificity of 100%. Pneumococcal RADT showed a sensitivity of 100% and specificity of 88.6%. Both RADT increased the pathogen identification rate in PPE compared to culture.

Treatment of lactational mastitis with Gualou Xiaoyong soup and painless lactation promoting technique: A case series.

BACKGROUND: Lactational mastitis is a common and frequently disease in clinical practice, characterized by acute inflammation of the mammary ducts and surrounding connective tissues. The main manifestations are damage to the mammary gland acini, edema, and invasion of inflammatory cells. If not treated properly, it may lead to the formation of breast abscesses, or even sepsis, septic shock, and chronic inflammation of the breast, which may cause the disease to persist or recur multiple times, so that the patients suffer extreme pain, and the health of both the mother and child are directly affected. This disease not only causes suffering for women but also may result in the cessation of breastfeeding. Therefore, rapid and effective treatment is particularly important. CASE SUMMARY: We report 3 cases of lactation mastitis patients showing good clinical efficacy after being treated with the Chinese medicine Gualou Xiaoyong soup and painless lactation promoting techniques. Gualou Xiaoyong soup combined with painless lactation promotion techniques can significantly reduce and eliminate the clinical symptoms of patients in the short term, and rapidly restore inflammatory indicators such as total white blood cells, neutrophils, C-reactive protein, and procalcitonin to normal levels. The patchy low echo area of the breast under B-ultrasound also disappears quickly. Therefore, we believe that this method is a good way to treat lactational mastitis and is worthy of clinical reference and research. However, this study has certain limitations: this study lacks a large sample of prospective controlled studies. Next, we will continue to collect relevant cases and conduct prospective case randomized controlled clinical studies. CONCLUSION: The treatment of lactation mastitis with Gualou Xiaoyong soup and painless lactation promoting techniques can achieve good clinical results.

[Management of Postoperative Surgical Site Infection and Empyema After Thoracic Surgery].

Surgical site infections (SSI)[wound infection, empyema] after thoracic surgery can lead to severe complications. Targeted antibiotic treatment and drainage are the keys. For the treatment of postoperative empyema without bronchopleural fistula, chest tube thoracostomy and irrigation with normal saline is effective. For postoperative empyema with bronchopleural fistula, open window thoracotomy is a good treatment option. Since the condition of empyema is different in each patient, treatment should be individualized depending on the patient's condition.

[Postoperative Complications of Open Window Thoracostomy:Report of a Case].

While open window thoracostomy is used to treat empyema with a high rate of infection control, it is an invasive procedure that leads to a decline in the quality of life. An 80-year-old man who had undergone wedge resection for pulmonary nodules subsequently developed postoperative empyema and underwent open window thoracostomy. After thoracostomy, the patient developed several complications, including bleeding from the lung surface and air leakage. Window closure was planned at this time;however, the plan was scuttled due to his low nutritional status and pulmonary air leakage. After the patient's condition improved with persistent conservative treatment, window closure was performed, and he overcame his complications. Patients with postoperative empyema requiring thoracostomy are at a high risk of developing postoperative complications. Therefore, it is important to manage the patients' condition persistently so that they can receive window closure at an appropriate time.

Aspiration Pneumonia Caused by Prevotella Causing Prothorax after Pulmonary Puncture: a Case Report.

BACKGROUND: Aspiration pneumonia in patients in immunocompetent populations is rare, and secondary pyothorax due to puncture operations during treatment has been reported rarely. METHODS: We report a confirmed case of aspiration pneumonia caused by Prevotella. The pathogen was detected and confirmed using percutaneous lung puncture and high-throughput next-generation sequencing (NGS). RESULTS: The patient developed secondary pyothorax, severe rash, and exacerbation of symptoms following the lung puncture. Finally, after adjusting the antibiotic regimen and performing chest drainage and washout, the patient's lesions were absorbed, symptoms improved, and the rash disappeared. CONCLUSIONS: Prevotella aspiration pneumonia can occur in immunocompetent individuals, and invasive bronchoscopic alveolar lavage may be considered as an option to reduce the risk of infectious organism translocation.
