necrotizing pneumonia

Necrotizing pneumonia (NP) is characterized by destruction of pulmonary tissue, resulting in multiple thin-walled cavities. There are limited reports on NP and parapneumonic effusion cases in children associated with Pseudomonas aeruginosa . Currently, there is no consensus regarding the optimal timing for video-assisted thoracoscopic surgery (VATS) following failure of chest tube placement and antibiotic treatment. A healthy 20-month-old child was hospitalized with symptoms of community-acquired pneumonia, progressing to severe NP and parapneumonic effusion...

OBJECTIVES: With the development of perinatal and neonatal intensive care medicine, the survival rate of very premature infants increases year by year. However, the incidence of bronchopulmonary dysplasia (BPD) increases year by year, which seriously affects the survival prognosis of very premature infants. How to prevent and treat BPD effectively has become the focus of neonatologists. This study aims to provide ideas for the prevention and treatment of BPD in very preterm infants via analyzing the clinical characteristics of BPD...

BACKGROUND: Necrotizing enterocolitis (NEC) is a multifactorial gastrointestinal disease with high morbidity and mortality among premature infants. However, studies with large samples on the factors of NEC in China have not been reported. This meta-analysis aims to systematically review the literature to explore the influencing factors of necrotizing enterocolitis in premature infants in China and provide a reference for the prevention of NEC. METHODS: PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), Wanfang and VIP databases were systematically searched from inception to February 2023...

Burkholderia cepacia ​​​​​​( B. cepacia ) complex is a highly resistant gram-negative pathogen known to cause lung infection in cystic fibrosis, chronic granulomatous disease, and immunocompromised patients. However, it may rarely infect immunocompetent patients as well. Here, we present the case of a 30-year-old male patient who was treated for B. cepacia pneumonia in the hospital, discharged with oral antibiotics, and returned two months later with recurring B. cepacia pneumonia and bacteremia...

BACKGROUND: CHPS dramatically affects infant growth and development and can even cause aspiration resulting from esophageal reflux. There is potential danger. CHPS is common, while CHPS with gas in the stomach wall and portal vein is rare. Gas in the stomach wall and portal vein are often the key features of more serious disease. It can be easily mistaken as a serious disease when patients with CHPS have gas in the stomach wall and portal vein. CASE PRESENTATION: A 56-day-old baby was hospitalized for aspiration pneumonia after vomiting without bile for 20 days...

A middle-aged man in his 50s, active smoker, presented to the pulmonary office for lung cancer evaluation. On a low-dose computed tomography for lung cancer screening, he was found to have an 8 mm endobronchial lesion in the right main stem bronchus. A PET-CT revealed no endobronchial lesion, but incidentally, fluorodeoxyglucose (FDG) avidity was present in the right hilar (SUV 13.2) and paratracheal lymph nodes (LNs). He underwent bronchoscopy and EBUS-TBNA of station 7 and 10 R LNs. The fine needle aspiration (FNA) revealed necrotizing epithelioid granuloma...

BACKGROUND: Fusobacterium necrophorum (F. necrophorum)-induced necrotizing pneumonia is a rare but severe pulmonary infection. Insufficient microbiological detection methods can lead to diagnostic difficulties. METHODS: We report a case of F. necrophorum lung abscess diagnosed by next-generation sequencing (NGS) of bronchoalveolar lavage fluid (BALF). RESULTS: BALF-NGS detected F. necrophorum, guiding subsequent targeted antibiotic therapy...

INTRODUCTION: Hydropneumothorax with a bronchopleural fistula is an infrequent but severe complication of necrotizing pneumonia associated with high morbidity and mortality. Few cases in the adult population have been reported. CASE REPORT: This is a case of a 76-year-old male patient who developed pneumonia caused by Pseudomonas aeruginosa and Klebsiella pneumoniae complicated by hydropneumothorax. He was managed conservatively with chest tube placement but denied surgical management and eventually died despite initial improvement...

Jehovah's Witnesses is a Christian denomination widely recognized for their steadfast refusal of blood transfusions, even when facing severe anemia. We describe a unique case of a 42-year-old Jehovah's Witness woman with severe iron deficiency anemia. She necessitated surgical correction of a malpositioned gastric band within the context of a complex necrotizing aspiration pneumonia secondary to esophageal obstruction. Medical management of this severe anemia has been a challenge as traditional approaches, like a blood transfusion, are not possible...

IMPORTANCE: Diagnostic delays are common in the emergency department (ED) and may predispose to worse outcomes. OBJECTIVE: To evaluate the association of annual pediatric volume in the ED with delayed diagnosis. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study included all children younger than 18 years treated at 954 EDs in 8 states with a first-time diagnosis of any of 23 acute, serious conditions: bacterial meningitis, compartment syndrome, complicated pneumonia, craniospinal abscess, deep neck infection, ectopic pregnancy, encephalitis, intussusception, Kawasaki disease, mastoiditis, myocarditis, necrotizing fasciitis, nontraumatic intracranial hemorrhage, orbital cellulitis, osteomyelitis, ovarian torsion, pulmonary embolism, pyloric stenosis, septic arthritis, sinus venous thrombosis, slipped capital femoral epiphysis, stroke, or testicular torsion...

A 54-year-old man was admitted for fever and dyspnea. He presented with severe COVID-19 pneumonia and elevated amylase and lipase levels. He received treatment for COVID-19 and possible acute pancreatitis (AP). Although pneumonia and amylase levels improved, a high-grade fever persisted. On day 39, abdominal CT revealed heterogenous liquid and non-liquid components with a well-defined wall around the pancreas, and he was diagnosed with infected walled-off necrosis (WON) after AP. It was concluded to be associated with COVID-19 because there were no identifiable causes, such as alcohol consumption, gallstones, or other viral infections...

BACKGROUND: The present study aimed to explore the maternal and perinatal risks in cases of monozygotic twins (MZT) following frozen-thawed embryo transfer (FET). METHODS: All twin births that were conceived following FET from 2007 to 2021 at Shanghai Ninth People's Hospital in Shanghai, China were retrospectively reviewed. The exposure variable was twin type (monozygotic and dizygotic). The primary outcome was the incidence of neonatal death while secondary outcomes included hypertensive disorders of pregnancy, gestational diabetes, intrahepatic cholestasis of pregnancy, placenta previa, placental abruption, preterm premature rupture of the membranes, Cesarean delivery, gestational age, birth weight, weight discordance, stillbirth, birth defects, pneumonia, respiratory distress syndrome, necrotizing enterocolitis, and neonatal jaundice...

Between September and November 2021, 5 snow leopards ( Panthera uncia ) and 1 lion ( Panthera leo ) were naturally infected with severe acute respiratory coronavirus 2 (SARS-CoV-2) and developed progressive respiratory disease that resulted in death. Severe acute respiratory syndrome coronavirus 2 sequencing identified the delta variant in all cases sequenced, which was the predominant human variant at that time. The time between initial clinical signs and death ranged from 3 to 45 days. Gross lesions in all 6 cats included nasal turbinate hyperemia with purulent discharge and marked pulmonary edema...

BACKGROUND: Coronavirus disease 2019 (COVID-19) tends to have mild presentations in children. However, severe and critical cases do arise in the pediatric population with debilitating systemic impacts and can be fatal at times, meriting further attention from clinicians. Meanwhile, the intricate interactions between the pathogen virulence factors and host defense mechanisms are believed to play indispensable roles in severe COVID-19 pathophysiology but remain incompletely understood. DATA SOURCES: A comprehensive literature review was conducted for pertinent publications by reviewers independently using the PubMed, Embase, and Wanfang databases...

Various studies have shown that oropharyngeal colostrum application (OPCA) is beneficial to preterm neonates. We performed a systematic review and meta-analysis to assess whether OPCA reduces the incidence of culture-proven neonatal sepsis in preterm neonates. Randomized controlled trials comparing OPCA with placebo or standard care in preterm neonates were included. Medline, Embase, Web of Science, Cumulated Index to Nursing and Allied Health Literature, Scopus, and CENTRAL were searched for studies published up to June 15, 2023...

Necrotizing pneumonia is a rare complication of community-acquired pneumonia, characterized by lung parenchymal destruction in affected areas. It has been sporadically documented over the years, mostly with insidious progression and a higher incidence among individuals with risk factors. Its diagnosis relies on clinical, analytical, and imaging data, and the treatment encompasses medical and surgical measures. The persistently high morbidity and mortality result from delayed diagnosis and the intricate therapeutic approach...

BACKGROUND: Recent alerts have highlighted an increase in group A streptococcal (GAS) infections since 2022 in Europe and the United States. Streptococcus pyogenes can cause limited skin or mucosal disease, but can also present as severe invasive disease necessitating critical care. We performed a multicenter retrospective study of patients with GAS infections recently admitted to Belgian intensive care units (ICUs) since January 2022. We describe patient characteristics and investigate the molecular epidemiology of the S...
