Relationship between Radiological Stages and Prognoses of Pneumocystis Pneumonia in Non-AIDS Immunocompromised Patients.

Background: Although radiological features of pneumocystis pneumonia (PCP) in non-Acquired Immune Deficiency Syndrome (AIDS) immunocompromised patients have been reported by other authors, there were no studies on the radiological stages of PCP previously. This study aimed to elucidate the radiological stages and prognoses of PCP in non-AIDS immunocompromised patients.

Methods: Retrospective analysis of radiological manifestations and prognoses of 105 non-AIDS PCP immunocompromised patients from August 2009 to April 2016 was conducted.

[Pulmonary capillary hemangiomatosis: a case report and literature review].

We reported a case of pulmonary capillary hemangiomatosis (PCH) and introduced its diagnosis, differential diagnosis, pathogenesis and development of treatment based on the review of Dana Point 2008 Classification of Pulmonary Hypertensiona and current literatures. A 43-year-old female presented progressive dyspnea, elevated pulmonary arterial pressures and CT pulmonary angiography (CTPA) imaging of main pulmonary arterial enlargement and wide spread ill-defined centrilobular nodules of ground-glass opacity. Her histologic features were proliferation of capillary channels within alveolar walls as well as muscularization of arterioles and medial hypertrophy of muscular pulmonary arteries.

[Retrospective analysis of 11 cases of respiratory amyloidosis].

Objective: To investigate the clinical manifestation, diagnosis and treatment of respiratory amyloidosis.

Methods: Data of 11 patients with respiratory amyloidosis diagnosed by biopsy in Peking University First Hospital from January 2002 to January 2012 were analyzed, and the related literatures were reviewed.

Results: In the last decade, 250 of 389 402 hospitalized patients were pathologically diagnosed as having amyloidosis, and 11 cases were pathologically confirmed to be respiratory amyloidosis.

[Retrospective analysis of relationship between radiological features and prognoses of pneumocystis pneumonia in non-AIDS immunocompromised patients].

Objective: To elucidate the relationship between the radiological features and prognoses of pneumocystis pneumonia (PCP) in non-acquired immunodeficiency syndrome (non-AIDS) immunocompromised patients.

Methods: Retrospective analyses were performed for the radiological features and prognoses of 36 non-AIDS immunocompromised PCP patients hospitalized at Peking University First Hospital from April 2006 to April 2010. There were 24 males and 12 females with an average age of (51.

A clinical comparative study of polymerase chain reaction assay for diagnosis of pneumocystis pneumonia in non-AIDS patients.

Background: Pneumocystis jirovecii pneumonia (PCP) is one of the most common and fatal infections in non-AIDS immunocompromised patients, which is difficult to diagnose by traditional morphologic methods. This study evaluated polymerase chain reaction (PCR) assays of Pneumocystis jirovecii mitochondrial large subunits ribosomal RNA in sputum and bronchioalveolar lavage fluid (BALF) for diagnosing PCP.

Methods: Sputum and BALF specimens from two groups were collected: one group (PCP group) included 20 patients definitely diagnosed of PCP by Gomori methenamine silver (GMS) stains of BALF; the other group (non-PCP group) included 40 patients.

[Medical thoracoscopic talc pleurodesis for malignant pleural effusion: an analysis of 27 cases].

Objective: To evaluate the efficacy and safety of talc poudrage pleurodesis via semi-rigid medical thoracoscopy in the treatment of malignant pleural effusions, as well as the factors that may influence the outcomes.

Methods: A series of 27 patients with malignant pleural effusion underwent medical thoracoscopic talc poudrage pleurodesis between July 2005 and September 2007 in Peking University First Hospital.

Results: There were 16 male and 11 female patients in the series, the average age being 65.

[Idiopathic pulmonary hemosiderosis in adults: report of two cases and literature review].

Objective: To describe the clinical, radiological and pathological characteristics of idiopathic pulmonary haemosiderosis (IPH) in adults and to evaluate the methods of diagnosis and treatment.

Methods: Two patients were successfully diagnosed and treated in our hospital and the literature on the subject was reviewed.

Results: Two adult patients (19 and 34 years old) diagnosed in our hospital had 5 and 10 years of history of hemoptysis respectively, and chest CT showed bilateral diffuse alveolar opacities over mid and lower zones.

[The diagnostic value of serum latex agglutination test for pulmonary cryptococcosis].

Objective: To evaluate the diagnostic value of serum cryptococcal capsular polysaccharide antigen latex agglutination test (LA) for pulmonary cryptococcosis.

Methods: Serum and lung biopsy specimens of 27 patients, who were suspected of having pulmonary cryptococcosis based on clinical presentations and imaging features, were collected from July 2000 to July 2007 in the First Hospital of Peking University. LA test and histopathological examination were performed in all the patients.

[Idiopathic pulmonary alveolar proteinosis: report of three cases and literature review].

To describe the clinical, radiological and pathological characteristics of idiopathic pulmonary alveolar proteinosis (I-PAP) and to evaluate the methods of diagnosis and treatment. Three patients were successfully diagnosed and treated in our hospital and the literature on the subject was reviewed. Three patients, two males and one female (mean age 46 years), were diagnosed averagely in 4 months.

[Retrospective analysis of three cases of pulmonary mucormycosis].

Objective: To describe the clinical characteristics of pulmonary mucormycosis and to evaluate the approaches to its diagnosis and treatment.

Methods: Three cases of pulmonary mucormycosis were successfully diagnosed by histopathologic examination of infected tissues obtained by fiberoptic bronchoscopy in this hospital. The clinical features of the cases were analyzed and the literature reviewed.

[H3N2 subtype of human influenza pneumonia with staphylococcal sepsis and staphylococcal pneumonia: report of one case].

To investigate the clinical characteristics, diagnosis and therapy of influenza pneumonia with staphylococcal infection. One patient in our hospital was diagnosed and the literatures on the subject were reviewed. The patient presented with high fever and dyspnea.

[A case of marginal zone B-cell lymphoma of the pulmonary mucosa-associated lymphoid tissue type].

Marginal zone B-cell lymphoma of the pulmonary mucosa-associated lymphoid tissue type (pulmonary MALT-MZL), a common kind of primary pulmonary lymphoma, is rare in pulmonary malignant tumors. One patient in our hospital was diagnosed by bronchoscope and the literatures on the subject were reviewed. The patient presented with periodical fever, cough and chest pain, and antibiotic therapy had no use.
