Coexisting Endogenous and Exogenous Llpold Pneumonia and Pulmonary Alveolar Proteinosis in a Patient with Neurodevelopmental Disease

We report a unique case of coexistingexogenous lipoid pneumonia, endogenous lipoid pneumonia (EU), and pulmonary alveolar proteinosis (PAP) in a 5-year-old patient with severe neurodevelop mental disease. The patient presented with gastroesophageal reflux and presumed chronic lung disease resulting from recurrent aspiration pneumonias and succumbed to respiratory failure. The autopsy showed lipid-laden macrophages and periodic acid-SchiJf9ositive granular matm'al i n alveolar spaces and multilamellated structures within both alveolar macrophages and extracellular debris.

These findings were similar to those in previous reports of coexisting E I P and PAP in the setting of gastroesophageal refux [I] . However, the present case diJfered by the presence of scattered large osmiophilic extracellular lipid vacuob. Besides strengthening the association between EIP and PAP and their relationship to gastroesophageal refux, this case suggests that t h q may arise together with exogenous lipoid pneumonia, through related mechanisms, in the setting of neurodevelopmental disease.     

肾移植术后并发卡氏肺孢子虫病活检的病理学研究

报告肾移植术后５例并发卡氏肺孢子虫肺炎。采用纤维支气管镜活检，分别对印片及组织进行银染和ＨＥ染色。病变为上皮细胞脱落，有时增生呈立方状；炎症反应；各种类型渗出物（包括泡沫状渗出物、泡沫细胞团及絮状蛋白渗出物）等３种改变。重点讨论了本病的组织病理学特征，并对不典型病变形成机理加以讨论。

Daily variation in circulating cytokines and acute-phase proteins correlates with clinical and laboratory indices in community-acquired pneumonia

Our objective was to investigate the initial levels of circulating proinflammatory cytokines, such as interleukin 1β (IL-1β), interleukin 6 (IL-6), and tumour necrosis factor alpha (TNF-α), of certain acute-phase proteins, such as C-reactive protein (CRP), fibrinogen (FBN) and albumin, and of the glycoprotein fibronectin at presentation and their daily variation during the clinical course of community-acquired pneumonia (CAP) in relation to clinical and laboratory indices of infection. Thirty otherwise healthy hospitalized patients aged 48 ± 3 years (mean ± SEM) and with bacteriologically confirmed CAP were studied prospectively. IL-1β and IL-6 were found to be 15-fold higher on admission (122 ± 9 pg mL^?1 and 60 ± 4 pg mL^?1 respectively), whereas TNF-α was three-fold higher (102 ± 5 pg mL^?1) than those of controls, all of them showing a decline towards normal. Initial CRP levels were increased 90-fold (416 ± 1 mg L^?1), whereas fibronectin levels were reduced (242 ± 9 mg dL^?1). The presence of parapneumonic effusion was associated with a higher TNF-α serum level (127 ± 7 vs. 86 ± 4 pg mL^?1, P = 0.0002), a more rapid daily decline in TNF-α (–7.2 ± 0.7 vs. ?3.8 ± 0.5 pg mL^?1 day^?1, P = 0.0005), a slower rate of decline in CRP (?42.8 ± 3.0 vs. ?54.6 ± 3.0 mg L^?1 day^?1, P = 0.02) and a slower rate of increase in FBN (5.9 ± 1.0 vs. 11.7 ± 1.0 mg dL^?1 day^?1), P = 0.001]. Furthermore, daily progression of serum levels of cytokines and acute-phase proteins correlated strongly with pyrexia, erythrocyte sedimentation rate (ESR), neutrophil count, alveolar–arterial oxygen difference and radiographic resolution, clinically manifested by improvement in the patients' condition.
