Pulmonary hemorrhage

RATIONALE: Marfan syndrome (MFS), which is a dominantly inherited connective tissue disease resulting from a mutation in the FBN1 gene, exhibits variable manifestations affecting the cardiovascular, musculoskeletal, ophthalmologic, and pulmonary systems. Notably, neurologic deficiency, which involves ischemic or hemorrhagic stroke, is a rare but severe manifestation. The safety of rt-PA treatment for ischemic stroke caused by MFS is still under discussion. PATIENT CONCERNS: In the current report, we discuss 3 atypical MFS cases presented as acute ischemic stroke, compared to those exhibiting cardiovascular and musculoskeletal abnormalities...

Hemoptysis is a rare presenting symptom in pediatric and young adult patients with a highly variable outcome ranging from an isolated mild occurrence to severe illness and death. Exercise-induced pulmonary hemorrhage (EIPH) has several reports in adult literature but has not previously been reported in pediatric patients. A 12-year-old female with a history of trisomy X (47, XXX), obesity, depression, anxiety, and obstructive sleep apnea presented to the pediatric pulmonology clinic after several episodes of hemoptysis...

UNLABELLED: Venous thromboembolism (VTE) (deep vein thrombosis and its complication, pulmonary embolism) is a major cause of morbidity and mortality in hospitalized patients and about 7% of these cases are due to immobility secondary to a neurological impairment. Acquired brain injury (ABI) has also been recognized as one of the main risk factors for VTE. Numerous epidemiological studies have been conducted to assess the risk factors for VTE in institutionalized polytrauma patients, although there is a lack of information about neurorehabilitation wards...

BACKGROUND: Prematurity and congenital heart disease (CHD) are the leading causes of neonatal mortality and morbidity. Limited data are available about the outcomes of premature infants with severe CHD. METHODS: We queried The National Inpatient Database using ICD-10 codes for premature patients (<37 weeks) with severe CHD from 2016 to 2020. Severe CHDs were grouped into three categories: A. left-sided lesions with impaired systemic output, B. Cyanotic CHD, and C...

Renal angiomyolipomas (AMLs) and pulmonary lymphangioleiomyomatosis (LAM) are two major presentations of tuberous sclerosis (TS), an autosomal dominant multisystem disorder. Renal AMLs can lead to life-threatening complications like hemorrhage and cause progressive renal failure requiring dialysis and kidney transplant. mTOR inhibitors showed promising results in TS patients with renal AMLs, LAM, and subependymal giant cell astrocytomas. This case report is a follow-up of a patient we reported in 2010 with giant AMLs and LAM who required an emergency nephrectomy for massive hemorrhage from giant left-sided AMLs...

BACKGROUND: Diffuse alveolar hemorrhage (DAH) is a potentially life-threatening condition that can occur due to a variety of disorders. Hence, rapid diagnosis and prompt initiation of appropriate treatment are imperative. CASES: A 55-year-old woman with a deep neck infection underwent emergent tonsillectomy. General anesthesia and surgery proceeded uneventfully. Upon transfer to the post-anesthesia care unit, ongoing respiratory distress and occasional expectoration of blood-tinged sputum were noted...

BACKGROUND: Bronchopulmonary dysplasia-associated pulmonary hypertension (BPD-PH) remains a devastating clinical complication seriously affecting the therapeutic outcome of preterm infants. Hence, early prevention and timely diagnosis prior to pathological change is the key to reducing morbidity and improving prognosis. Our primary objective is to utilize machine learning techniques to build predictive models that could accurately identify BPD infants at risk of developing PH. METHODS: The data utilized in this study were collected from neonatology departments of four tertiary-level hospitals in China...

Anti-glomerular basement membrane (GBM) disease is a rare and severe vasculitis that affects the glomerular and pulmonary capillaries and has an incidence of less than 2 cases per million individuals per year. Anti-GBM disease is mediated by autoantibodies against the α3 chain of type IV collagen. In the majority of cases, the autoantibodies are of the immunoglobulin G (IgG) class, with rare cases being mediated by immunoglobulin M (IgM) or immunoglobulin A (IgA); there are less than 15 IgA-mediated cases reported in the literature worldwide...

BACKGROUND: Ischemic and hemorrhagic stroke incidence tends to be higher among minority racial and ethnic groups. The effect of race and ethnicity following an aneurysmal subarachnoid hemorrhage (aSAH) remains poorly understood. Thus, we aimed to explore the association between race and ethnicity and aSAH outcomes. METHODS: Single-center retrospective review of patients with aSAH from January 2009 to March 2023. Primary outcome was in-hospital mortality. Secondary outcomes included delayed cerebral ischemia, cerebral infarction, radiographic and symptomatic vasospasm, pulmonary complications, epileptic seizures, external ventricular drain placement, and modified Rankin Scale score at discharge and 3-month follow-up...

OBJECTIVE: Despite the lack of prospective evidence for the perioperative use of dexamethasone in meningioma surgery, its use is well established in the daily routine of several centers. The present study evaluates the effect of dexamethasone on postoperative complications, peritumoral T2/FLAIR hyperintensity, and progression-free survival in patients with supratentorial meningiomas undergoing resection. METHODS: A total of 148 patients who underwent resection of a primary sporadic supratentorial meningioma at the authors' institution between 2018 and 2020 were included in this retrospective cohort...

BACKGROUND Neurogenic pulmonary edema (NPE) is a rare complication of neurological insults, such as traumatic brain injury and intracranial hemorrhage, in children. NPE frequently accompanies left ventricular (LV) dysfunction mediated via central catecholamine surge and inflammation. A high serum natriuretic (BNP) level was prolonged even after the LV contraction was improved in this case with severe myocardial injury. The overloading stress to the LV wall can last several days over the acute phase of NPE. CASE REPORT A 6-year-old boy developed NPE after the removal of a brain tumor in the cerebellar vermis, which was complicated by hydrocephalus...

Breath-hold divers, also known as freedivers, are at risk of specific injuries that are unique from those of surface swimmers and compressed air divers. Using peer-reviewed scientific research and expert opinion, we created a guide for medical providers managing breath-hold diving injuries in the field. Hypoxia induced by prolonged apnea and increased oxygen uptake can result in an impaired mental state that can manifest as involuntary movements or full loss of consciousness. Negative pressure barotrauma secondary to airspace collapse can lead to edema and/or hemorrhage...

AUDIENCE: The target audiences for this team-based learning (TBL) activity are resident physicians and medical students. INTRODUCTION: According to the Centers for Disease Control and Prevention (CDC), nearly half of the adults in the United States have hypertension,1 which is a leading cause of cardiovascular disease and premature death.2 In extreme cases, patients may present in hypertensive emergencies, defined as an acute, marked elevation of systolic blood pressure >180mmHg or diastolic blood pressure >120mmHg with evidence of organ dysfunction...

Drug-induced lung injury (DILI) occurs when exposure to a drug leads to inflammation and, eventually, fibrosis of the lung interstitium. While DILI is a rare side effect of antipsychotic medication, once it manifests, it requires detailed investigation and prompt treatment. Diagnosing DILI can be challenging at times due to its similarity to conditions such as infectious diseases or interstitial pneumonia induced by other causes. We hereby report a fatal case of suspected DILI associated with olanzapine. A 61-year-old female with a history of delusional disorder was admitted to our hospital due to worsened psychiatric symptoms...

Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a rare and potentially life-threatening autoimmune disease characterized by antineutrophil cytoplasmic antibody (ANCA)-associated vasculature inflammation. It presents as a systemic autoimmune disease with necrotizing granulomatous inflammation and pauci-immune small vessel vasculitis. This case initially posed a diagnostic challenge due to its atypical presentation and was misdiagnosed as hypersensitivity pneumonitis. The avian precipitin screening assay was positive in our patient, which may be consistent with bird breeder's lung disease or a non-specific reactivity of the chicken antigen test...

BACKGROUND: Anticoagulation therapy is the mainstay of therapy for patients with venous thromboembolism (VTE). However, continuing or stopping anticoagulants after the first 3 to 6 months is a difficult decision that requires ascertainment of the risk of bleeding and recurrent VTE. Despite the development of several statistical models to predict bleeding, the benefit of machine learning (ML) models has not been investigated in depth. OBJECTIVES: To assess the benefits of ML algorithms in bleeding risk evaluation in VTE patients and gain insight into their baseline information...

Reperfusion is considered as the cornerstone of the treatment of high-risk pulmonary embolism (PE). However, when thrombolysis is contraindicated and surgery or interventional therapy is not available, the treatment of high-risk PE becomes very difficult. To our knowledge, there are no reports of successful treatment of high-risk PE with low-dose anticoagulation. On November 30, 2021, a 56-year-old male patient with subarachnoid hemorrhage was admitted to the emergency department of the First Affiliated Hospital of Chongqing Medical University...

This issue of Chinese Journal of Tuberculosis and Respiratory Diseases published an interesting case illustrating the identification, treatment, and post-treatment management of a high-risk pulmonary thromboembolism (PTE) that occurred during surgery. It was a high-risk case of PTE, but during treatment, the risk stratification changed to medium-high risk. We should dynamically assess risk stratification and develop diagnosis and treatment plans based on changes in the patient's condition. At the same time, there was a high risk of bleeding in this patient...

BACKGROUND: Current literature lacks guidance on the safety of administering anticoagulation in acute ischemic stroke with emergent indications that require anticoagulation other than atrial fibrillation. Therefore, we tend to rely on studies investigating acute ischemic stroke in atrial fibrillation for anticoagulation recommendations. METHODS: We retrospectively reviewed data for patients with acute ischemic stroke who had a non-atrial fibrillation emergent indication for anticoagulation (e...

The first-choice imaging test for visualization of thromboemboli in the pulmonary vasculature in patients with suspected acute pulmonary embolism (PE) is multidetector computed tomography pulmonary angiography (CTPA) - a readily available and widely used imaging technique. Through technological advancements over the past years, alternative imaging techniques for the diagnosis of PE have become available, whilst others are still under investigation. In particular, the evolution of artificial intelligence (AI) is expected to enable further innovation in diagnostic management of PE...
