Physician's awareness of lung cancer screening and its related medical radiation exposure in Korea.

Through a survey on perception of lung cancer screening and accompanying medical radiation exposure in Korea, the present study was to investigate its current situations and evaluate various perception of physicians regarding it in order to propose measures for improvements.

Bedside ultrasound diagnosis of a malpositioned central venous catheter: A case report.

Central venous catheter (CVC) placement is commonly performed in intensive care unit. And CVC placement is associated with risks including CVC malposition, pneumothorax. Many of the previously reported cases are about catheter misplacement detected by bedside ultrasound, chest x-ray (CXR) and computed tomography. In this case, malposition was detected by bedside ultrasound incidentally particularly with no clinical manifestation.

Management of pulmonary embolism after recent intracranial hemorrhage: A case report.

Venous thromboembolism may result from prolong immobilization following intracerebral hemorrhage. Massive pulmonary embolism with associated right heart failure is life-threatening, requiring treatment with anticoagulants or even thrombolytic agents. However, these drugs are contraindicated after a recent hemorrhagic episode, as they may induce further hemorrhage. There are no guidelines for treatment in these circumstances.

Successful treatment of plasma exchange for rapidly progressive interstitial lung disease with anti-MDA5 antibody-positive dermatomyositis: A case report.

As the initial treatment of rapidly progressive interstitial lung disease (RPILD) with antimelanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab)-positive dermatomyositis (DM) patients, a combination of corticosteroids, cyclophosphamide, and calcineurin inhibitor is recommended. However, some of these patients have poor prognoses despite such intensive treatment. Other more effective treatments are desired. We report the case of an anti-MDA5 Ab-positive DM patient who had developed RPILD despite intensive treatments; she was treated successfully by a short-term plasma exchange (PE).

Fiberoptic bronchoscopic treatment of blood aspiration and use of sugammadex in a patient with epistaxis: A case report.

In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications.

S-1-based concurrent chemoradiotherapy in the treatment of locally advanced non-small cell lung cancer: A systematic review and meta-analysis protocol.

Lung cancer is the leading cause of cancer-related deaths in the world, and non-small cell lung cancer accounts for > 75% of all lung cancer cases. Cisplatin-based concurrent chemoradiotherapy has become the standard treatment for locally advanced non-small cell lung cancer (NSCLC). Third-generation chemotherapy agents plus cisplatin have been most commonly used in concurrent chemoradiotherapy, which is also associated with more adverse effects and acute toxicities. S-1 as an oral chemotherapeutic agent exhibits higher antitumor activity, less adverse effects, and better biological availability. Recently, studies illustrated S-1-based concurrent chemoradiotherapy also had excellent effects in the treatment of locally advanced NSCLC.

Treatment of primary tracheal glomus tumors: Two case reports and a literature review.

Glomus tumors (GTs) are rare soft tissue neoplasms. Several treatment options have been reported for tracheal GTs including thoracotomy, bronchoscopic electrocautery, Nd: YAG laser, and cryotherapy. However, few studies have evaluated the ideal treatment for tracheal GTs.

Development of massive pulmonary embolism during echocardiographic imaging: A case report.

Pulmonary embolism (PE) is a common diagnostic consideration for patients who present to the emergency department (ED) with chest pain, dyspnea, or both. In addition, PE has a very high mortality in patients who are hemodynamically unstable. An electrocardiography, bedside transthoracic echocardiogram, and computed tomography pulmonary angiogram are usually performed to confirm the diagnosis.

Human immunodeficiency virus infection and mortality risk among lung cancer patients: A systematic review and meta-analysis.

Previous studies have suggested that patients with human immunodeficiency virus (HIV) infection are at higher risk of lung cancer, but the impact of HIV infection on the risk of mortality among lung cancer patients is still unclear. We conducted a systematic review and meta-analysis to clarify the association between HIV infection and mortality risk among lung cancer patients.

Icotinib and whole-brain radiotherapy for the treatment in patients with brain metastases from EGFR-mutant nonsmall cell lung cancer: A retrospective study.

This study aimed to explore the effect and toxicity of icotinib and whole-brain radiotherapy (IWBRT) for the treatment of brain metastases from nonsmall cell lung cancer (BMNSCLC) with epidermal growth factor receptor (EGFR)-mutant among Chinese Han population.A total of 55 patients with EGFR-mutant BMNSCLC were included. They received orally icotinib (125 mg/tablet, 125 mg each time, 3 times daily) until disease progression. In addition, they also underwent whole-brain radiotherapy (3-Gy fractions once daily, 5 days weekly for a total dose of 30 Gy) in an attempt to extend their survival time. The outcomes consisted of complete response (CR), partial response (PR), stable disease (SD), progress disease (PD), overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). In addition, toxicity was also recorded in this study.The CR, PR, SD, PD, ORR, PFS, and OS were 38.2%, 52.8%, 5.4%, 3.6%, 90.1%, 12.5%, and 48.0% months, respectively. In addition, mild toxicity was observed in this study.This study demonstrated that IWBRT is efficacious with acceptable toxicity for patients with EGFR-mutant BMNSCLC among Chinese Han population.

Mandibular metastasis as the first clinical indication of occult lung adenocarcinoma with multiple metastases: A case report.

Although metastases to the oral and maxillofacial region (OMR) are rare, the lung is the most common primary site metastasizing to the OMR.

Pediatric Emergency Noninvasive Ventilation.

Noninvasive ventilation (NIV) has emerged as a powerful tool for the pediatric emergency management of acute respiratory failure (ARF). This therapy is safe and well tolerated and seems to frequently prevent both the need for invasive mechanical ventilation and the associated risks/complications. Although NIV can be the primary treatment of ARF resulting from multiple respiratory disease states, it must be meticulously monitored and, when unsuccessful, may aid in preoxygenation for prompt endotracheal intubation and invasive mechanical ventilation. The following article reviews the physiologic effects of NIV and its role in common respiratory diseases encountered in pediatric emergency medicine.

What to Do when Babies Turn Blue: Beyond the Basic Brief Resolved Unexplained Event.

The term "brief resolved unexplained event" was created to replace "apparent life-threatening event," narrowing the definition and providing evidence-based guidelines for management. The emphasis is placed on using clinical clues to classify patients as low risk or exclude them from the categorization altogether. Infants who meet low-risk classification can be briefly observed in the emergency department and be discharged home. Infants who demonstrate elements suggestive of a specific etiology should be evaluated and treated accordingly. Patients who demonstrate no specific findings yet who are high risk should be evaluated for the most common etiologies of apneic events and be admitted.

Bronchiolitis: From Practice Guideline to Clinical Practice.

The American Academy of Pediatrics' clinical practice guideline in bronchiolitis was last updated in 2014 with recommendations to improve care for pediatric patients with bronchiolitis. As most treatments of bronchiolitis are supportive, the guideline minimizes the breadth of treatments previously used and cautions the use of tests and therapies that have a limited evidence base. Emergency physicians must be familiar with the guidelines in order to apply best practices appropriately.

Targeted Therapy and Immunotherapy in the Treatment of Non-Small Cell Lung Cancer.

The treatment strategy in advanced non-small cell lung cancer (NSCLC) has evolved from empirical chemotherapy to a personalized approach based on histology and molecular markers of primary tumors. Targeted therapies are directed at the products of oncogenic driver mutations. Immunotherapy facilitates the recognition of cancer as foreign by the host immune system, stimulates the immune system, and alleviates the inhibition that allows the growth and spread of cancer cells. The authors describes the role of targeted therapy and immunotherapy in the treatment of NSCLC, patterns of disease present on imaging studies, and immune-related adverse events encountered with immunotherapy.

Lung Cancer: Posttreatment Imaging: Radiation Therapy and Imaging Findings.

In this review, we discuss the different radiation delivery techniques available to treat non-small cell lung cancer, typical radiologic manifestations of conventional radiotherapy, and different patterns of lung injury and temporal evolution of the newer radiotherapy techniques. More sophisticated techniques include intensity-modulated radiotherapy, stereotactic body radiotherapy, proton therapy, and respiration-correlated computed tomography or 4-dimensional computed tomography for radiotherapy planning. Knowledge of the radiation treatment plan and technique, the completion date of radiotherapy, and the temporal evolution of radiation-induced lung injury is important to identify expected manifestations of radiation-induced lung injury and differentiate them from tumor recurrence or infection.

Update of MR Imaging for Evaluation of Lung Cancer.

Since MR imaging was introduced for the assessment of thoracic and lung diseases, various limitations have hindered its widespread adoption in clinical practice. Since 2000, various techniques have been developed that have demonstrated the usefulness of MR imaging for lung cancer evaluation, and it is now reimbursed by health insurance companies in many countries. This article reviews recent advances in lung MR imaging, focusing on its use for lung cancer evaluation, especially with regard to pulmonary nodule detection, pulmonary nodule and mass assessment, lung cancer staging and detection of recurrence, postoperative lung function prediction, and therapeutic response evaluation and prediction.

Dilemmas in Lung Cancer Staging.

The advent of the 8th edition of the lung cancer staging system reflects a further meticulous evidence-based advance in the stratification of the survival of patients with lung cancer. Although addressing many limitations of earlier staging systems, several limitations in staging remain. This article reviews from a radiological perspective the limitations of the current staging system, highlighting the process of TNM restructuring, the residual issues with regards to the assignment of T, N, M descriptors, and their associated stage groupings and how these dilemmas impact guidance of multidisciplinary teams taking care of patients with lung cancer.

Staging Lung Cancer: Metastasis.

The updated eighth edition of the tumor, node, metastasis (TNM) classification for lung cancer includes revisions to T and M descriptors. In terms of the M descriptor, the classification of intrathoracic metastatic disease as M1a is unchanged from TNM-7. Extrathoracic metastatic disease, which was classified as M1b in TNM-7, is now subdivided into M1b (single metastasis, single organ) and M1c (multiple metastases in one or multiple organs) descriptors. In this article, the rationale for changes in the M descriptors, the utility of preoperative staging with PET/computed tomography, and the treatment options available for patients with oligometastatic disease are discussed.

Staging Lung Cancer: Regional Lymph Node Classification.

This article reviews regional lymph node assessment in lung cancer. In the absence of a distant metastasis, the absence or location of lung cancer spread to a regional mediastinal lymph node affects treatment options and prognosis. Regional lymph node maps have been created to standardize assessment of the N descriptor. The International Association for the Study of Lung Cancer lymph node map is used for the standardization of N descriptor assessment. CT, PET/CT with fluorodeoxyglucose, endobronchial ultrasound-guided and/or esophageal ultrasound-guided biopsy, and mediastinoscopy are common modalities used to determine the N descriptor.

Tumor Staging of Lung Cancer: Essential Concepts for the Radiologist.

Several important modifications have been proposed for the tumor (T) descriptor for lung cancers. New size cutoffs have been determined and there are new T descriptors for adenocarcinoma in situ, minimally invasive adenocarcinoma, and part-solid adenocarcinomas with a solid component > 0.5 cm to 3 cm (T1a, T1b, T1c). There are also recommendations for multifocal adenocarcinoma, which are classified by the lesion with the highest level T descriptor, and the number of lesions is indicated. Knowledge of these changes is important in the appropriate clinical staging of patients with lung cancer.

Lung Cancer Biopsies.

Image-guided percutaneous transthoracic needle biopsy (PTNB) is a well-established and minimally invasive technique for evaluating pulmonary nodules. Implementation of a national lung screening program and increased use of chest computed tomography have contributed to the frequent identification of indeterminate pulmonary nodules that may require tissue sampling. The advent of biomarker-driven lung cancer therapy has led to increased use of repeat PTNB after diagnosis. Percutaneous insertion of markers for preoperative localization of small nodules can aid in minimally invasive surgery and radiation treatment planning. This article discusses PTNB, patient selection, and biopsy technique, including minimizing and managing complications.

Missed Lung Cancer.

The chest radiograph is one of the most commonly used imaging studies and is the modality of choice for initial evaluation of many common clinical scenarios. Over the last two decades, chest computed tomography has been increasingly used for a wide variety of indications, including respiratory illnesses, trauma, oncologic staging, and more recently lung cancer screening. Diagnostic radiologists should be familiar with the common causes of missed lung cancers on imaging studies in order to avoid detection and interpretation errors. Failure to detect these lesions can potentially have serious implications for both patients as well as the interpreting radiologist.
