OBJECTIVES
The pharmacokinetics of antibiotics in pleural fluid during pleural infections has been poorly described. This study aimed to explore amoxicillin and metronidazole diffusion into the pleural space.
METHODS
This was an ambispective, single-centre study that included patients with complicated parapneumonic effusion or pleural empyema managed with repeated therapeutic thoracentesis as first-line treatment between 2014 and 2022. Pleural steady-state or trough concentrations of amoxicillin and metronidazole were measured, with a lower limit of quantification of 5 mg/L.
RESULTS
Seventy paired blood and pleural samples were analysed from 40 patients. The median (interquartile range) patient age was 55 years (45-67 years) and 88% were male. The median patient weight was 65.8 kg (57.3-82 kg) and median plasma albumin concentration was 29.7 g/L (23.7-33.9 g/L). Median creatinine clearance was 106 mL/min (95-117 mL/min). Median amoxicillin pleural concentrations in patients treated with oral, bolus and continuous intravenous administrations (6 g/day) were, respectively, 5.2 (<5-6.4), 9.4 (8-13.1) and 10.8 (7.1-13.1) mg/L. Pleural concentrations were <5 mg/L in 5/11 samples (45%) with oral treatment and 6/59 (10%) with intravenous treatment. Median metronidazole pleural concentrations were 18.4 (15.7-22.8) mg/L, with all patients being treated orally (1.5 g/day).
CONCLUSIONS
Oral metronidazole (1.5 g/day) and intravenous amoxicillin (6 g/day) achieved therapeutic targets in pleural fluid in most cases, but oral amoxicillin did not.

A 91-year-old woman was brought to our hospital with altered consciousness. Blood tests showed an increased ammonia level of 468 μg/dL and a normal liver function. Chest computed tomography showed massive right pleural effusion with loculation. We immediately performed chest drainage using two drainage tubes. The pleural effusate pH was 8.5. We diagnosed her with right empyema leading to hyperammonemia and initiated ampicillin/sulbactam therapy. However, she developed progressive renal failure and died on the third day. Empyema caused by urease-producing bacteria can lead to hyperammonemia. This is the first report of hyperammonemia due to empyema in the English literature.

Review
Infective pleural effusions are mainly represented by parapneumonic effusions and empyema. These conditions are a spectrum of pleural diseases that are commonly encountered and carry significant mortality and morbidity rates reaching upwards of 50%. The causative etiology is usually an underlying bacterial pneumonia with the subsequent seeding of the infectious culprit and inflammatory agents to the pleural space leading to an inflammatory response and fibrin deposition. Radiographical evaluation through a CT scan or ultrasound yields high specificity and sensitivity, with features such as septations or pleural thickening indicating worse outcomes. Although microbiological yields from pleural studies are around 56% only, fluid analysis assists in both diagnosis and prognosis by evaluating pH, glucose, and other biomarkers such as lactate dehydrogenase. Management centers around antibiotic therapy for 2-6 weeks and the drainage of the infected pleural space when the effusion is complicated through tube thoracostomies or surgical intervention. Intrapleural enzymatic therapy, used to increase drainage, significantly decreases treatment failure rates, length of hospital stay, and surgical referrals but carries a risk of pleural hemorrhage. This comprehensive review article aims to define and delineate the progression of parapneumonic effusions and empyema as well as discuss pathophysiology, diagnostic, and treatment modalities with aims of broadening the generalist's understanding of such complex disease by reviewing the most recent and relevant high-quality evidence.

Empyema necessitans is a rare entity that consists on the development of an abscess that begins in the pleural space and then extends to the adjacent tissues. This case shows a rare and very late complication of a total pneumonectomy, emphasizing the importance of the multidisciplinary approach and the potential of endoscopic therapy with over-the-scope clips.

BACKGROUND/NEED
Pleural empyemas carry a high morbidity and mortality. Some can be managed with medical treatment but most require some form of surgery with the goals to remove the infected material from the pleural space and to help re-expand the collapsed lung. Keyhole surgery by Video Assisted Thoracoscopy Surgery (VATS) is rapidly becoming a common approach to deal with early stage empyemas to avoid larger, more painful thoracotomies that hinder recovery. However, the ability to achieve those aforementioned goals is often hindered by VATS surgery due to the instruments available.
METHODOLOGY AND DEVICE DESCRIPTION
We have developed a simple instrument called the "VATS Pleural Debrider" to achieve those goals in empyema surgery that can be used in keyhole surgery.
PRELIMINARY RESULTS
We have used this device in over 90 patients with no peri-operative mortality and a low re-operation rate.
CURRENT STATUS
Used in routine urgent/emergency pleural empyema surgery across 2 cardiothoracic surgery centres.

Chest Nov 2023The optimal treatment for community-acquired childhood pneumonia complicated by empyema remains unclear.
BACKGROUND
The optimal treatment for community-acquired childhood pneumonia complicated by empyema remains unclear.
RESEARCH QUESTION
In children with parapneumonic effusion or empyema, do hospital length of stay and other key clinical outcomes differ according to the treatment modality used?
STUDY DESIGN AND METHODS
A living systematic review of randomized controlled trials (RCTs) was conducted by searching the Cochrane Central Register of Controlled Trials, Embase, Latin American and Caribbean Health Sciences Literature, Ovid MEDLINE, and Web of Science Core Collection databases. Eligible RCTs included patients aged < 18 years and compared two of the following treatment modalities: antibiotics alone, chest tube insertion with or without fibrinolytics, video-assisted thoracoscopic surgery (VATS), and decortication via thoracotomy. A network meta-analysis was performed to evaluate treatment effects on hospital length of stay (LOS), the primary outcome.
RESULTS
Eleven trials including a total of 590 patients were selected for the network meta-analysis. Compared with a chest tube alone, a chest tube with fibrinolytics, thoracotomy, and VATS were all associated with shorter LOS, with a mean difference of 5.05 days (95% CI, 2.46-7.64), 6.33 days (95% CI, 3.17-9.50), and 5.86 days (95% CI, 3.38-8.35), respectively. No substantial differences in LOS were observed between the latter three interventions. None of the 11 RCTs compared antibiotics alone vs other types of treatment. Most trials reported peri-procedural complications and the need for reintervention, but the descriptions differed significantly between trials, preventing meta-analysis. In trials reporting health care-associated costs, fibrinolytics had cost advantages compared with VATS. Short- and long-term morbidity and mortality were very low, regardless of the treatment modality.
INTERPRETATION
The results of this network meta-analysis showed that a chest tube alone was associated with a longer LOS compared with other treatment modalities. The lower cost associated with a chest tube plus fibrinolytics warrants consideration when choosing between treatment options, given similar LOS and clinical outcomes compared with the other modalities.

A lung abscess is characterized as a clinical ailment arising from the localized suppurative necrosis of lung parenchyma. This condition primarily results from the complications of aspiration pneumonia due to anaerobic microorganisms originating from the oral cavity. Clinically, patients typically manifest symptoms such as fever, malaise, and a productive cough persisting over several weeks. The majority of lung abscess cases acquired within the community stem from anaerobic bacterial infections, often exhibiting a polymicrobial nature. We present a 51-year-old female with intrapulmonary abscess and empyema, with isolation of species. She has a 25-pack-year smoking history. Two weeks prior to arrival at our facility, she experienced intermittent shortness of breath, fever, and subjective fever. Her primary care physician ordered an outpatient computed tomography (CT) which showed evidence of a large right-sided fluid collection. Initial chest X-ray at our facility revealed extensive opacification of the middle and right lower hemithorax, believed to be a large-sized pleural effusion with adjacent pneumonia or atelectasis. She was given a working diagnosis of right-sided empyema. Cardiothoracic surgery was consulted and video-assisted thoracoscopic surgery (VATS) was performed. A very large collection of grossly purulent material was evacuated and revealed a large intrapulmonary abscess. Over 400 cc of frank pus was collected and sent for microbiological analysis. Anaerobic culture demonstrated 3+ species and 3+ species. The genus consists of a small, strictly anaerobic, gram-negative cocci that lacks flagella, spores, and capsules. This genus obtains energy from the utilization of short-chain organic acids that are present in the oral cavity and intestinal tract. Oral is strongly associated with biofilms, causing human oral infectious diseases such as periodontitis and dental caries. Literature states that this organism has been isolated in a limited number of chronic pneumonitis cases. To date, the most common organism isolated from lung abscesses is in adult patients and in pediatric patients. We strive to elucidate the distinctive clinical presentation evident in this case, alongside a comprehensive understanding of the unusual pathogens identified in the disease's pathogenesis.

Pediatric Surgery International Nov 2023Both thoracic drainage and video-assisted thoracic surgery (VATS) are available treatment for pleural empyema in pediatric patients.
BACKGROUND
Both thoracic drainage and video-assisted thoracic surgery (VATS) are available treatment for pleural empyema in pediatric patients.
MATERIALS AND METHODS
This retrospective multicenter study includes pediatric patients affected by pleural empyema treated from 2004 to 2021 at two Italian centers. Patients were divided in G1 (traditional approach) and G2 (VATS). Demographic and recovery data, laboratory tests, imaging, surgical findings, post-operative management and follow-up were analyzed.
RESULTS
70 patients with a mean age of 4.8 years were included; 12 (17.1%) in G1 and 58 (82.9%) in G2. Median surgical time was 45 min in G1, 90 in G2 (p < 0.05). Mean duration of thoracic drainage was 7.3 days in G1, 6.2 in G2 (p > 0.05). Patients became afebrile after a mean of 6.4 days G1, 3.9 in G2 (p < 0.05). Mean duration of antibiotic therapy was 27.8 days in G1, 25 in G2 (p < 0.05). Mean duration of postoperative hospital stay was 16 days in G1, 12.1 in G2 (p < 0.05). There were 4 cases (33.3%) of postoperative complications in G1, 17 (29.3%) in G2 (p > 0.05). 2 (16.7%) patients of G1 needed a redosurgery with VATS, 1 (1.7%) in G2.
CONCLUSIONS
VATS is an effective and safe procedure in treatment of Pleural Empyema in children: it is associated to reduction of chest tube drainage, duration of fever, hospital stay, time of antibiotic therapy and recurrence rate.

Boerhaave's syndrome (BS) is a non-iatrogenic spontaneous esophageal perforation that, if not appropriately recognized and managed, can cause localized infections such as mediastinitis, pneumonia, and empyema, as well as systemic infections with significant morbidity and mortality rates. An autonomous 83-year-old male presented to the emergency department with a three-day history of behavioral changes. Three days earlier, the patient had a self-limited episode of cough, nonspecific thoracalgia, palpitations, prostration, and pallor. On physical examination, he was alert but had temporal disorientation, hypoxemia, and pulmonary auscultation with abolished breath sounds in the middle third of the left chest. Laboratory tests showed hypoxemia, elevated C-reactive protein (28.2 mg/dL), and D-dimer (3.28 µg/mL). A chest X-ray revealed periaortic small bubbles, left atelectasis, and left pleural effusion. Computed tomographic angiography of the chest showed infra-carinal esophageal rupture, small bubbles of the anterior pneumomediastinum, and a loculated left pleural empyema. Mediastinitis and empyema due to BS were assumed. He underwent left thoracic drainage, broad-spectrum antibiotics, and the placement of a surgical esophageal prosthesis. He was discharged after 48 days. The condition known as BS is frequently misdiagnosed, mostly as a result of the lack of a preexisting pathological background and the wide array of potential symptoms that may manifest. The diagnosis in this particular case was rendered particularly complex due to the combination of an unusual presentation and a delayed seeking of medical attention. Against all expectations, our patient was successfully treated.
