Abstract
BACKGROUND Some studies have observed an increased incidence of necrotizing pneumonia (NP) in recent years. This might be related to the emergence of non-vaccine S. pneumoniae serotypes after PCV7 introduction although it is suggested that evolutionary factors may have modified the virulence and the interactions of pneumococci. The aim of this study was to clinically and microbiologically define NP in the population served by the three major paediatric hospitals in Barcelona (Catalonia, Spain). METHODS A prospective observational study was conducted in patients <18 years hospitalized due to invasive pneumococcal disease (January 2012-June 2016). Data of confirmed cases of pneumococcal NP (diagnosed by culture or DNA detection and serotyped) were collected. PCV13 was not systematically administered in Catalonia during the study period, but was available in the private market so the vaccination coverage in children increased from 48.2% to 74.5%. RESULTS 35 cases of NP were identified. 77.1% of cases were associated with empyema. In the first 4 years, a trend to a decrease in NP incidence was observed (p=0.021), especially in children <5 years (p=0.006). Serotype 3 was responsible for 48.6% of NP cases. Five patients with NP due to serotype 3 were fully vaccinated for their age with PCV13. CONCLUSIONS Serotype 3 has a preeminent role in pneumococcal NP and was associated with all PCV13 vaccination failures. Although in our series the incidence does not seem to be increasing, evolution of pneumococcal NP rates should be monitored after inclusion of PCV13 in the systematic calendar.

Abstract
INTRODUCTION Necrotizing pneumonia (NP) is a serious complication of community-acquired pneumonia characterised by the destruction of normal lung parenchyma. No study has evaluated the repercussions of the lung damage in the years following the episode. The aim of this study was to assess the long-term impact on lung function and respiratory symptoms in children hospitalised due to NP. METHODS We analysed outcomes in children given a diagnosis of NP between January 2003 and April 2016. We selected patients aged more than 4 years capable of undergoing a lung function test, that had been followed up for at least 2 years. The patients completed a respiratory questionnaire and underwent a lung function test. RESULTS We included a total of 24 patients (12 male). The median age at the time of diagnosis was 28 months, the median length of stay was 15 days, and 18 patients required pleural drainage. The mean duration of follow-up after NP was 8.75 years. During the evaluation, none of the patients exhibited asthma, cough, or exercise-induced symptoms. Three children had a second episode of pneumonia that did not require hospital admission. The spirometry results were the following (given as mean±standard deviation): FEV1 Z-score, -0.47±0.65; FVC Z-score, -0.56±0.73; and FEV1/FVC Z-score, 0.19±0.98. We found no evidence of obstructive pulmonary disease or restrictive patterns. CONCLUSIONS The long-term outcomes of paediatric NP are good. However, patients exhibited mildly impaired lung function several years after the episode. We recommend follow-up of these patients due to potential impairments in lung function in adulthood.

Abstract
BACKGROUND Necrotizing pneumonia (NP) is a severe complication of community-acquired pneumonia. The impact of 13-valent pneumococcal conjugate vaccine (PCV13) on the epidemiology of NP in children has not been assessed. PATIENTS AND METHODS Medical records of children less than 18 years admitted with NP to two pediatric hospitals in Italy between 2005 and 2019 were reviewed. The following four periods were defined: 2005-2010 (pre-PCV13), 2011-2013 (early post-PCV13), 2014-2016 (intermediate post-PCV13), and 2017-2019 (late post-PCV13). RESULTS Forty-three children (median age, 44 months) were included. Most of them (93%) were previously healthy. No differences in age, sex, season of admission, comorbidity, clinical presentation, or hospital course were identified between pre-PCV13 and post-PCV13 periods. A significant decrease in the rate of NP-associated hospitalizations was found between the early (1.5/1000 admissions/year) and the intermediate (0.35/1000 admissions/year) post-PCV13 period (p = .001). An increased trend in admissions was found thereafter. Streptococcus pneumoniae was the most common agent detected in both periods (pre-PCV13: 11/18, 61%; post-PCV13: 13/25, 52%). Serotype 3 was the most common strain in both periods (pre-PCV13: 3/11, 27%; post-PCV13; 4/13, 31%). There were no changes in the etiology over time, but most patients with Streptococcus pyogenes or Staphylococcus aureus infection were admitted during the post-PCV13 period. CONCLUSIONS The hospitalization rate for NP in children decreased a few years after the implementation of PCV13 immunization in Italy. However, an increased trend in admissions was found thereafter. S. pneumoniae was the most frequent causal agent in both pre- and post-PCV13 periods. Pneumococcal serotypes were mainly represented by Strain 3.

Abstract
Complicated community-acquired pneumonia in a previously well child is a severe illness characterised by combinations of local complications (eg, parapneumonic effusion, empyema, necrotising pneumonia, and lung abscess) and systemic complications (eg, bacteraemia, metastatic infection, multiorgan failure, acute respiratory distress syndrome, disseminated intravascular coagulation, and, rarely, death). Complicated community-acquired pneumonia should be suspected in any child with pneumonia not responding to appropriate antibiotic treatment within 48-72 h. Common causative organisms are Streptococcus pneumoniae and Staphylococcus aureus. Patients have initial imaging with chest radiography and ultrasound, which can also be used to assess the lung parenchyma, to identify pleural fluid; CT scanning is not usually indicated. Complicated pneumonia is treated with a prolonged course of intravenous antibiotics, and then oral antibiotics. The initial choice of antibiotic is guided by local microbiological knowledge and by subsequent positive cultures and molecular testing, including on pleural fluid if a drainage procedure is done. Information from pleural space imaging and drainage should guide the decision on whether to administer intrapleural fibrinolytics. Most patients are treated by drainage and more extensive surgery is rarely needed; in any event, in low-income and middle-income countries, resources for extensive surgeries are scarce. The clinical course of complicated community-acquired pneumonia can be prolonged, especially when patients have necrotising pneumonia, but complete recovery is the usual outcome.

Abstract
BACKGROUND In children, necrotizing pneumonia (NP) is an uncommon, severe complication of pneumonia. It is characterized by destruction of the underlying lung parenchyma resulting in multiple small, thin-walled cavities and is often accompanied by empyema and bronchopleural fistulae. REVIEW NP in children was first reported in children in 1994, and since then there has been a gradual increase in cases, which is partially explained by greater physician awareness and use of contrast computed tomography (CT) scans, and by temporal changes in circulating respiratory pathogens and antibiotic prescribing. The most common pathogens detected in children with NP are pneumococci and Staphylococcus aureus. The underlying disease mechanisms are poorly understood, but likely relate to multiple host susceptibility and bacterial virulence factors, with viral-bacterial interactions also possibly having a role. Most cases are in previously healthy young children who, despite adequate antibiotic therapy for bacterial pneumonia, remain febrile and unwell. Many also have evidence of pleural effusion, empyema, or pyopneumothorax, which has undergone drainage or surgical intervention without clinical improvement. The diagnosis is generally made by chest imaging, with CT scans being the most sensitive, showing loss of normal pulmonary architecture, decreased parenchymal enhancement and multiple thin-walled cavities. Blood culture and culture and molecular testing of pleural fluid provide a microbiologic diagnosis in as many as 50% of cases. Prolonged antibiotics, draining pleural fluid and gas that causes mass effects, and maintaining ventilation, circulation, nutrition, fluid, and electrolyte balance are critical components of therapy. Despite its serious nature, death is uncommon, with good clinical, radiographic and functional recovery achieved in the 5-6 months following diagnosis. Increased knowledge of NP's pathogenesis will assist more rapid diagnosis and improve treatment and, ultimately, prevention. CONCLUSION It is important to consider that our understanding of NP is limited to individual case reports or small case series, and treatment data from randomized-controlled trials are lacking. Furthermore, case series are retrospective and usually confined to single centers. Consequently, these studies may not be representative of patients in other locations, especially when allowing for temporal changes in pathogen behaviour and differences in immunization schedules and antibiotic prescribing practices.

Abstract
Surgical treatment of lung diseases is based on removal of the affected lung tissue, achieved by atypical or anatomic lung resection. Infectious lung diseases are generally treated by medical therapy, including medications, chest physiotherapy, bronchoscopic toilet, and respiratory rehabilitation. Surgical management of infectious disease of the lung is integrated in the multispecialty care. This article focuses exclusively on nonresectional surgery and other alternatives to lung resection and addresses bacterial infection and fungal disease of the lung.

Abstract
Community-acquired pneumonia (CAP) occurs more often in early childhood than at almost any other age. Many microorganisms are associated with pneumonia, but individual pathogens are difficult to identify, which poses problems in antibiotic management. This article reviews the common as well as new, emerging pathogens, as well as the guidelines for management of pediatric CAP. Current guidelines for pediatric CAP continue to recommend the use of high-dose amoxicillin for bacterial CAP and azithromycin for suspected atypical CAP (usually caused by Mycoplasma pneumoniae) in children.

Abstract
Les pneumopathies infectieuses peuvent se compliquer, du fait de facteurs liés aux germes, à l’hôte ou à l’interaction entre les deux, par la survenue d’une nécrose et/ou d’une destruction du parenchyme pulmonaire. La nécrose et la destruction du parenchyme pulmonaire sont à l’origine de deux entités cliniques principales, les abcès pulmonaires et les pneumonies nécrosantes (PN). Les PN sont des entités rares mais dont le pronostic est redoutable. Elles sont caractérisées par une hépatisation diffuse, possiblement bilatérale du parenchyme pulmonaire avec cavitations et nécrose. Les PN sont généralement associées à un sepsis sévère et à une insuffisance respiratoire aiguë. Nous envisagerons la physiopathologie et le traitement médical qui comprend des mesures symptomatiques, le support des différentes défaillances d’organe, en particulier respiratoires, et le traitement antibiotique. Les indications chirurgicales et leurs modalités seront aussi détaillées. Une prise en charge multidisciplinaire associant réanimateurs, pneumologues, infectiologues, radiologues, chirurgiens et kinésithérapeutes doit permettre d’améliorer les taux de survie et surtout la qualité de vie des patients à distance d’une PN.

Abstract
BACKGROUND Necrotizing pneumonia is generally considered a rare complication of pneumococcal infection in adults. We systematically studied the incidence of necrotizing changes in adult patients with pneumococcal pneumonia and examined the severity of infection, role of causative serotypes, and association with bacteremia. METHODS We used a database of all pneumococcal infections identified at our medical center between 2000 and 2010. Original readings of chest X-rays (CXR) and computerized tomography (CT) were noted. Images were then independently reevaluated by 2 radiologists. The severity of disease at admission was assessed using SMART-COP and Pneumonia Outcomes Research Team (PORT) scoring systems. RESULTS In 351 cases of pneumococcal pneumonia, necrosis was reported in no (0%) original CXR readings and in 6 of 136 (4.4%) CTs. With rereading, 8 of 351 (2.3%) CXR and 15 of 136 (11.0%) CT had necrotizing changes. Overall, these changes were identified in 23 of 351 (6.6%) patients. The incidence of bacteremia and the admitting SMART-COP and PORT scores were similar in patients with and without necrosis (P = 1.00, P = .32, and P = .54, respectively). Type 3 pneumococcus was more commonly isolated from patients with necrosis than from patients without necrosis (P = .05), but 10 other serotypes were also implicated in 16 cases for which the organism was available for typing. CONCLUSIONS Necrotizing changes in the lungs were seen in 6.6% of a large series of adults with pneumococcal pneumonia but were often overlooked on initial readings. Patients with necrosis were not more likely to have bacteremia or more severe disease. Type 3 pneumococcus was the most commonly identified serotype.

Abstract
BACKGROUND Severe necrotizing pneumococcal pneumonia may progress to the development of bronchopleural fistula (BPF). The purpose of this study was to describe the clinical courses and identify risk factors for the development of bronchopleural fistula in children with pneumococcal pneumonia. Histopathologic features of children receiving surgical resections of the lung because of BPF were analyzed to explore the pathogenesis of destructive lung disease caused by Streptococcus pneumoniae. METHODS A total of 112 cases of culture-proven pneumococcal pneumonia were identified between January 2001 and March 2010 at Chang Gung Children's Hospital. The medical charts of all cases of culture-proven pneumococcal pneumonia were reviewed. RESULTS Pneumococcal pneumonia in 18 children (18/112, 16.1%) was complicated by BPF. As compared with children without BPF, children with BPF had significantly lower white blood cell counts at admission (P = 0.03) and significantly longer durations of fever and hospitalization (P < 0.001). Multivariate analysis revealed that acute respiratory failure (odds ratio = 8.9; 95% confidence interval = 2.6-30.9; P = 0.001) and serotype 19A infection (odds ratio = 5.0; 95% confidence interval = 1.2-22.1; P = 0.03) were risk factors for the development of BPF. Histopathologic analyses were available for 12 children who underwent surgical resections of the lung. Coagulative necrosis with pulmonary infarction was found in 11 of the 12 cases. CONCLUSIONS Serotype 19A was strongly associated with BPF. Vaccines containing this serotype will be important for prevention.
