A 72-year-old patient was admitted to the medical intensive care unit due to a right-sided, hospital-acquired pneumonia and septic shock with respiratory failure and deterioration of chronic renal failure. During hospitalization the patient required hemodynamic support with norepinephrine and dobutamine, mechanical ventilation and hemodialysis. The patient suffered a non-ST segment elevation myocardial infarction (NSTEMI) and received dual antiplatelet therapy. After 14 days an acute intrapulmonary infiltrate of unknown origin developed, accompanied by fever and a significant increase of the C‑reactive protein (CRP) level...

BACKGROUND: Bronchoscopy with transbronchial and endobronchial biopsy and transbronchial needle aspiration is an important diagnostic tool in the pulmonologist's armamentarium. Safety in patients with pulmonary hypertension is controversial and many bronchoscopists consider this as a contraindication for the procedure. OBJECTIVES: To evaluate safety of bronchoscopy in patients with echocardiographic pulmonary hypertension and to compare with patients without it...

Broncholithiasis is an often overlooked condition and has been associated with symptoms such as cough, hemoptysis, and recurrent respiratory infections. The most common mechanism of a broncholith formation is the enlargement and subsequent erosion of a lymph node into an adjacent airway. Here, we describe this entity in a patient with advanced allergic bronchopulmonary aspergillosis, with chronic hypercapnic respiratory failure, and with frequent infective exacerbations. These frequent exacerbations were initially attributed to the poor lung function of the patient and the inability to cough out the secretions...

Pulmonary alveolar proteinosis (PAP) is a rare condition characterized by dysfunctional alveolar macrophages, which ineffectively clear surfactant and typically cause mild hypoxemia. Characteristic Computed Tomography findings are septal reticulations superimposed on ground-glass opacities in a crazy paving pattern, with a clear juxtaposition between affected and unaffected parenchyma. While traditionally PAP was diagnosed via biopsy, bronchoalveolar lavage (BAL) is usually sufficient; the fluid appears milky, and on microscopic examination there are foamy macrophages with eosinophilic granules and extracellular hyaline material that is Periodic Acid-Schiff positive...

PURPOSE OF REVIEW: Loss of skeletal muscle mass and cachexia are important manifestations of chronic obstructive pulmonary disease and have been associated with breathlessness, functional limitation and poor prognosis. A number of other life-limiting illnesses, including cancer and chronic heart failure as well as acute conditions seen in ICU such as sepsis, are characteristically associated with cachexia and sarcopenia. These conditions may have respiratory muscle atrophy of sufficient magnitude to contribute to the development of breathlessness and associated functional limitation...

A 54-year-old man was referred to our hospital because of progressive dyspnea. Chest computed tomography showed multiple nodular shadows with a peripheral ground-glass halo. His clinical condition continued to deteriorate with the development of progressive respiratory failure requiring mechanical ventilation. A histological examination of a transbronchial lung biopsy revealed choriocarcinoma. The patient died within nine days of admission. A histological examination of the right testis during an autopsy revealed a burned-out testicular tumor consisting of a teratoma and a fibrous scar...

Persistent pulmonary hypertension of the newborn (PPHN) is the most common neonatal form and mostly reversible after a few days with improvement of the underlying pulmonary condition. When pulmonary hypertension (PH) persists despite adequate treatment, the severity of parenchymal lung disease should be assessed by chest CT. Pulmonary vein stenosis may need to be ruled out by cardiac catheterisation and lung biopsy, and genetic workup is necessary when alveolar capillary dysplasia is suspected. In PPHN, optimisation of the cardiopulmonary situation including surfactant therapy should aim for preductal SpO2between 91% and 95% and severe cases without post-tricuspid-unrestrictive shunt may receive prostaglandin E1 to maintain ductal patency in right heart failure...

Complement-mediated hemolytic uremic syndrome (otherwise known as atypical HUS) is a rare disorder of uncontrolled complement activation that may be associated with heart failure. We report the case of a 49-year-old female with no history of heart disease who presented with microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Given her normal ADAMSTS13 activity, evidence of increased complement activation, and renal biopsy showing evidence of thrombotic microangiopathy, she was diagnosed with complement-mediated HUS...

BACKGROUND: Interstitial lung diseases (ILDs) are disorders of the lung parenchyma. The pathogenesis, clinical manifestations, and prognosis of ILDs vary depending on the underlying disease. The onset of most ILDs is insidious, but they may also present subacutely or require hospitalization for management. ILDs that may present subacutely include acute interstitial pneumonia, connective tissue disease-associated ILDs, cryptogenic organizing pneumonia, acute eosinophilic pneumonia, drug-induced ILDs, and acute exacerbation of idiopathic pulmonary fibrosis...

Over the last decades, post-infectious glomerulonephritis underwent major changes in its epidemiology, pathophysiology, and outcomes. We are reporting a case of IgA-dominant post-infectious glomerulonephritis (IgA-PIGN) presenting as a fatal pulmonary-renal syndrome. An 86-year-old Filipino man presented with worsening dyspnea, hemoptysis, and decreased urine output over 2 weeks. Past medical history is significant for hypertension, chronic kidney disease stage III, and pneumonia 3 weeks prior treated with intravenous cefazolin for methicillin-sensitive Staphylococcus aureus bacteremia...

RATIONALE: Children's Interstitial and Diffuse Lung Disease (chILD) is a heterogeneous group of disorders that is challenging to categorize. In previous study, a classification scheme was successfully applied to children 0 to 2 years of age who underwent lung biopsies for chILD. This classification scheme has not been evaluated in children 2 to 18 years of age. OBJECTIVES: This multicenter interdisciplinary study sought to describe the spectrum of biopsy-proven chILD in North America and to apply a previously reported classification scheme in children 2 to 18 years of age...

Diffuse alveolar hemorrhage (DAH) is characterized by the presence of hemoptysis, anemia, and the presence of diffuse parenchymal infiltrates on imaging studies. Idiopathic pulmonary hemosiderosis (IPH) is an uncommon cause of diffuse alveolar hemorrhage (DAH) and is classically known to present in childhood. Adult-onset IPH is extremely rare. We report the case of a 48-year-old female patient who presented with hemoptysis and acute hypoxic respiratory failure, requiring intubation and mechanical ventilation...

OBJECTIVES: Surgical lung biopsy plays an important role in providing pathologic results, thus complementing the diagnostic rationale for suspected interstitial lung diseases. We performed a systematic review and meta-analysis regarding the diagnostic yield and postoperative mortality rate of surgical lung biopsy in patients with suspected interstitial lung diseases because of the wide variation in previously reported effectiveness and safety concerns. METHODS: We systematically searched for published studies between 2000 and 2014 evaluating surgical lung biopsy in the diagnosis of interstitial lung diseases...

BACKGROUND AIMS: Bone marrow mononuclear cells (BM-MNCs) and bone marrow-derived mesenchymal stem stromal cells (BM-MSCs) could have therapeutic potential for numerous conditions, including ischemia-related injury. Cells transplanted intravascularly may become entrapped in the lungs, which potentially decreases their therapeutic effect and increases the risk for embolism. METHODS: Twelve pigs were divided into groups of 3 and received (99m)Tc- hydroxymethyl-propylene-amine-oxime-labeled autologous BM-MNCs or allogeneic BM-MSCs by either intravenous (IV) or intra-arterial (IA) transplantation...
