Alveolar hemorrhage (AH) is a heterogeneous clinical syndrome with a high mortality rate that is characterized by extensive bleeding into the alveolar spaces. AH usually develops secondary to immunological disease and, less frequently, to drug use. Presently described is the case of an 86-year-old woman with AH who had been using rivaroxaban for 6 months.

BACKGROUND: Osteomas are infrequent benign bone tumors of uncertain etiology. They are usually situated at extremities and their occurrence in the jaws is relatively rare. There are 3 types of osteoma: central, peripheral, and extraskeletal. Preoperative presumptive diagnosis is performed by means of radiography using orthopantomographs, computerized tomographs, or cone beam scans. Treatment is surgical and consists of careful exeresis and curettage of the adjacent tissue. In recent years, piezoelectric surgery has been used to treat bone pathologies in the maxillofacial area, orthopedic surgery, and neurosurgery...

Acute lung injury (ALI) is a heterogeneous disease with the hallmarks of alveolar capillary membrane injury, increased pulmonary edema and pulmonary inflammation. The commonest direct etiological factor for ALI is usually parenchymal lung infection or hemorrhage. Reactive oxygen species (ROS) generated by NADPH oxidase (NOX2) are thought to play an important role in the pathophysiology of ALI. Glucose-6-phosphate dehydrogenase (G6PD) plays an important role both in production of ROS as well as their removal through supply of NADPH...

BACKGROUND: The outcome of extracorporeal membrane oxygenation (ECMO) might be influenced by its complications. Only limited information is available regarding the pathologic consequences of ECMO especially in the era of modern ECMO technology. METHODS: We studied the histopathologic findings in autopsy lungs of patients treated with ECMO as compared to those without ECMO. Autopsy files were queried for cases with ECMO. An age and gender-matched control group, comprised of patients who died in the Intensive Care Unit without acute respiratory distress syndrome, pneumonia, or ECMO, was compared with patients with ECMO for cardiac reason...

BACKGROUND: Pulmonary tumor thrombotic microangiopathy is a special type of tumor thromboembolism. We report the case of a patient who developed pulmonary tumor thrombotic microangiopathy with alveolar hemorrhage. Almost all patients with pulmonary tumor thrombotic microangiopathy die within 1 week of the onset of dyspnea; however, the prognosis in this case was better, with 10 weeks of survival from presentation. CASE PRESENTATION: A 62-year-old Japanese man was referred to our hospital with a 4-week history of dyspnea on exertion and severe pulmonary hypertension...

Diffuse alveolar hemorrhage (DAH) is a life-threatening complication of systemic lupus erythematosus (SLE). Although infrequent, its mortality is very high. While there are no established therapeutic guidelines, DAH has been traditionally managed with high-dose intravenous (IV) corticosteroids, cyclophosphamide, and plasma exchange. The efficacy of alternative therapies such as rituximab has been described only in a few cases. Herein, we report a 25-year-old Hispanic man who presented with acute-onset SLE manifested by polyarthralgia, nephritis, seizures, pancytopenia, severe hypocomplementemia, and elevated anti-dsDNA antibodies...

Ex vivo liver resection combined with autotransplantation is a recently introduced approach to cure end-stage hepatic alveolar echinococcosis (HAE), which is considered unresectable by conventional radical resection due to echinococcal dissemination into the crucial intrahepatic conduits and adjacent structures. This manuscript aims discuss the manipulation details and propose reasonable indications for this promising technique. All patients successfully underwent liver autotransplantation with no intraoperative mortality...

Classical polyarteritis nodosa (PAN) is a necrotizing arteritis affecting medium-sized vessels. A 73-year-old gentleman who presented with progressive anemia and scant hemoptysis developed acute kidney injury over the course of hospital admission. Kidney biopsy was initially interpreted as consistent with cephalosporin-associated acute interstitial nephritis (AIN) and acute tubular injury (ATI). After oral prednisone (5 days), the patient was discharged with improving serum creatinine. Two days later, he presented with diffuse alveolar hemorrhage...

We describe the case of a 73-year-old man who experienced dry cough and exertional dyspnea after dabigatran administration. Chest radiographs revealed the development of bilateral consolidative and ground glass opacity, and transbronchial lung biopsy showed organized materials in the alveolar spaces with moderate inflammatory infiltrate and focal fibrosis. Lung opacity gradually disappeared after discontinuing dabigatran. To date, there has been only one report regarding dabigatran-induced lung injury, except for alveolar hemorrhage and eosinophilic pneumonia...

It is well known that some disorders can cause concomitant kidney dysfunction with lung involvement. These syndromes, characterized by the simultaneous presence of intra-alveolar hemorrhage and acute glomerulonephritis, are caused by numerous and variable disorders. The most frequent are the antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis and Goodpasture syndrome. A quick discerning of the underlying causes and initiation of adequate treatment is crucial to prevent acute respiratory failure and irreversible loss of renal function...

A 65-year-old man was diagnosed with granulomatosis with polyangiitis (GPA) based on the detection of high MPO-ANCA, vasculitis and granulomas in a lung biopsy specimen and crescentic glomerulonephritis in a kidney biopsy specimen. Soon after the initiation of intravenous methylprednisolone pulse therapy (mPSL pulse) and intravenous cyclophosphamide pulse therapy (IVCY), the patient experienced cough and hemoptysis. Based on emerging anemia and bilateral diffuse lung consolidation on computed tomography, we judged that diffuse alveolar hemorrhage (DAH) was complicated by GPA...
