  • Besides respiratory infection, COVID-19 has many neurological symptoms not only loss of smell and taste but also fatigue and brain fog. But it is a challenge to treat the neurological symptoms especially of anosmia and ageusia. In order to search for the therapeutic methods, the geographical diversity and pathological mechanisms of the COVID-19 and two symptoms were investigated from the latest clinical studies. Because the environmental conditions of the monsoon climate zone of East Asia and the Mediterranean and Oceanic climate zone of Italy, Britain, United States and tropical Brazil are different, each of diverse etiology and internal milieu should be considered differently in the treatment. SARS-CoV-2 exhibits the dampness-like characteristics and the olfactory and gustatory disorders are particularly more common than other flu or cold. and it tends to show features of damaging the lung qi of olfaction and heart-spleen qi of gustation. The mechanisms of olfactory and gustatory loss are various according to precursory, inflammatory, non-inflammatory and sequelar forms, so the therapeutic method should be designed for each period and pathology. If the process of inflammation arises from nasal and respiratory, olfactory epithelium to the central nervous structure by way of blood brain barrier, the treatment should be corresponded with the stage and depth of pathogen place. And if the olfactory loss is asymptomatic or in the initial stage, it can be applied intranasal topical scent therapy to relieve temporary locking of qi movement, but maybe also used in parallel together with herbs of relieving dampness toxin latent in the lung parenchyma.

  • Background: Spread through air spaces (STAS) has recently emerged as a prognostic factor in lung adenocarcinoma, but little is known about the association of STAS and its grade with recurrence in neuroendocrine tumors (NETs). This study investigated the prognostic effect of STAS grade in NETs after curative resection. Methods: Seventy-seven patients were retrospectively reviewed, including 9 with typical carcinoid (TC), 6 with atypical carcinoid (AC), 26 with large cell neuroendocrine carcinoma (LCNEC), and 36 with small cell carcinoma (SCC). STAS was defined as the presence of floating tumor cells within air spaces in the lung parenchyma beyond the edge of the main tumor. STAS was classified as grade 1 or 2 depending on whether it was found within or beyond one ×10 objective lens field away from the main tumor margin, respectively. Results: Fifty-four patients (70%) had STAS, including 22% with TC, 50% with AC, 69% with LCNEC, and 86% with SCC. Patients with STAS had more nodal metastasis, lymphatic and vascular invasion, tumor necrosis, and tumor subtypes other than TC. Among STAS cases, grade 2 STAS was present in 33% of AC, 78% of LCNEC, and 87% of SCC. The 5-year recurrence-free survival (RFS) rate was 81%, 63%, and 35% in patients with no STAS, grade 1, and grade 2 STAS, respectively. Multivariate analysis found that grade 2 STAS was an independent negative prognostic factor for RFS. Conclusion: Although STAS itself was not associated with a poor prognosis, grade 2 STAS was an independent negative prognostic factor for RFS.

  • Idiopathic pulmonary fibrosis (IPF) can be defined as a progressive chronic pulmonary disease showing scarring in the lung parenchyma, thereby resulting in increase in mortality and decrease in the quality of life. The pathophysiologic mechanism of fibrosis in IPF is still unclear. Repetitive microinjuries to alveolar epithelium with genetical predisposition and an abnormal restorative reaction accompanied by excessive deposition of collagens are involved in the pathogenesis. Although the two FDA-approved drugs, pirfenidone and nintedanib, are under use for retarding the decline in lung function of patients suffered from IPF, they are not able to improve the survival rate or quality of life. Therefore, a novel therapeutic agent acting on the major steps of the pathogenesis of disease and/or, at least, managing the clinical symptoms of IPF should be developed for the effective regulation of this incurable disease. In the present review, we tried to find a potential of managing the clinical symptoms of IPF by natural products derived from medicinal plants used for controlling the pulmonary inflammatory diseases in traditional Asian medicine. A multitude of natural products have been reported to exert an antifibrotic effect in vitro and in vivo through acting on the epithelial-mesenchymal transition pathway, transforming growth factor (TGF)- β-induced intracellular signaling, and the deposition of extracellular matrix. However, clinical antifibrotic efficacy of these natural products on IPF have not been elucidated yet. Thus, those effects should be proven by further examinations including the randomized clinical trials, in order to develop the ideal and optimal candidate for the therapeutics of IPF.

  • This case report presents the case of a 49-year-old man who presented to our level I trauma center after sustaining injuries in an altercation with local law enforcement in which he was shot with a less lethal bean bag and tased. In a primary survey, a penetrating left supraclavicular wound was noted in addition to a taser dart lodged in his flank. No other traumatic findings were noted in a secondary survey. Given hemodynamic stability, completion imaging was obtained, revealing a foreign body in the left lung, a left open clavicle fracture, a C5 tubercle fracture, a possible grade I left vertebral injury, and a left first rib fracture. Soft tissue gas was seen around the left subclavian and axillary arteries, although no definitive arterial injury was identified. The bean bag projectile was embedded in the parenchyma of the left lung on cross-sectional imaging. The patient underwent thoracotomy for removal of the projectile and hemostasis. A thoracotomy was chosen as the operative approach due to concerns about significant bleeding upon foreign body removal. A chest tube was placed and subsequently removed on postoperative day 5. The patient was discharged on postoperative day 7. At a 2-week outpatient follow-up visit, the patient was doing well. This case report is the first to describe this outcome for a drag-stabilized bean bag. Although law enforcement officers utilize bean bag projectiles as a "less lethal" means of crowd control and protection, these ballistics pose significant risk and can result in serious injury.

  • 과민성폐렴(hypersensitivity pneumonitis)은 기도를 통해 흡입된 항원물질이 세기관지와 폐포에 면역매개 염증병변을 일으켜 발생하는 간질성폐질환(interstitial lung disease)이다. 다양한 유기물질이 발생원인으로 작용할 수 있기에 환자의 흉부영상검사와 임상증상을 통해 과민성폐렴을 의심하고 직업 또는 주변 환경을 통해 노출되는 항원을 파악하는 것이 과민성폐렴 진단의 핵심이다. 하지만 다양한 임상증상과 진행 형태로 인해 간질성폐질환 환자의 진단에서 과민성폐렴을 정확히 감별할 수 있느냐는 풀기 쉽지 않은 주제이다. 이에 2020년 미국흉부학회, 일본호흡기학회 그리고 라틴아메리카흉부학회는 과민성폐렴 진단에 대한 새로운 임상진료지침을 발표하였다. 이번 임상진료지침은 과민성폐렴 진단에 있어서 흉부 고해상도 전산화단층촬영(high-resolution CT; 이하 HRCT)의 역할을 강조하며 과민성폐렴에 대한 새로운 분류 기준도 제시하고 있다. 본 종설은 흉부 HRCT 내용을 포함해 새롭게 소개된 과민성폐렴 진단에 대한 전반을 살펴보고자 한다.

  • We report the case of a 32-year-old woman presenting with intermittent chest pain resulted from a migratory acupuncture needle. The patient received acupuncture treatment approximately 3 years prior to this presentation, for the treatment of chronic left shoulder and lumbar pain after delivery. Chest radiography revealed a retained needle in the lingular segmental area. Video-assisted thoracoscopy was then used to remove the migratory acupuncture needle attached between the lingular segmental lobe and the pericardial fat. The patient recovered without complications and was discharged home.

  • The lymphangioleiomyomatosis(LAM) is a rare disorder, which afflicts mainly young woman of childbearing age, characterized by proliferation of immature smooth muscle cell in the lymphatics. We experienced a case of LAM in 26-years-old pregnant woman, confirmed pathologically by inguinal lymph node biopsy. She has suffered from exertonal dyspnea and dry coughing. The symptoms and chest X-ray were aggravated with pregnancy, but improved after delivery with two times of pregnancy. The chest X-ray showed diffuse reticulonodular infiltration and chest HRCT showed diffuse scattered tiny thin-walled cyst of lung parenchyma. We noted chylous ascites of which triglyceride level is 396 mg/dl. After delivery, the symptoms were getting better. We treated with medroxyprogesterone and planned close observation and follow-up.
