Chronic pneumonitis of infancy (CPI) is a very rare interstitial lung disease. Its pathological features differ from other types of interstitial pneumonia that occur in adults and children. The mortality rate of CPI is high, even with treatment. We report a case of a 3 month old girl diagnosed with CPI after an open lung biopsy who improved after proper treatment.

PURPOSE: Healthcare-associated pneumonia (HCAP) has been proposed as a new category of pneumonia. However, epidemiological studies for HCAP in South Korea are limited. This study aimed to reveal the differences between HCAP and community-acquired pneumonia (CAP), especially in elderly patients, in university-affiliated hospital in South Korea. MATERIALS AND METHODS: We conducted a retrospective observational study of patients with HCAP and CAP (older than 60 years old) who were hospitalized between January 2007 and December 2008. We compared the baseline characteristics, comorbidities, severity, pathogen distribution, antibiotics, and clinical outcomes. RESULTS: A total of 210 patients were evaluated, including 35 patients with HCAP (17%) and 175 with CAP (83%). The most common causative organism was Streptococcus pneumoniae in CAP (33.3%), whereas, Staphylococcus aureus was most common pathogen in HCAP (40.0%). Initial inappropriate antibiotics (6.3% vs. 22.9%; p < 0.005) and initial treatment failure (15.4% vs. 31.4%; p = 0.018) were more frequent in HCAP than CAP. However, mortality (11.4% vs. 5.7%; p = 0.369) was not different between the two groups. CONCLUSION: The present study provides additional evidence that HCAP should be distinguished from CAP, even in elderly patients, in South Korea. Physicians should consider S. aureus and MDR pathogens in selecting initial empirical antibiotics of HCAP in South Korea.

Trichosporon beigelii belongs to the family of Cryptococcaceae. T. beigelii is a rare causative agent of invasive pneumonia in immunocompromised patients. T. beigelii pneumonia is characterized by persistent fever unresponsive to broad-spectrum antibiotic the- rapy, coughing with bloody sputum, and rapidly progressive dyspnea. Its diagnosis should be based on clinical suspicion and confirmed by culture and histologic examination of biopsy tissue. We describe an ALL patient with T. beigelii pneumonia developed during severe pancytopenic period after salvage chemotherapy.

Community-acquired pneumonia (CAP) is the third leading cause of death worldwide and one of the most commonly infectious diseases. Its epidemiological characteristics vary with host and immune status, and corresponding pathogen spectrums migrate over time and space distribution. Meanwhile, with the outbreak of COVID-19, some unconventional treatment strategies are on the rise. This article reviewed the epidemiological characteristics, pathogen spectrum and treatment direction of CAP in China over the years, and aimed to provide guidance for the diagnosis and treatment of CAP in clinical practice.
