Isolated left bronchial isomerism that was incidentally detected as a severe obstructive ventilatory disturbance in an asymptomatic adult patient: A case report.

Rationale: Left bronchial isomerism is generally associated with abnormal arrangement of the atrium and abdominal viscera; therefore, its diagnosis is confirmed in early childhood.

Patient Concerns: Here we report a rare case involving a 36-year-old man with isolated left bronchial isomerism that presented as an asymptomatic severe obstructive ventilatory disturbance during pulmonary function tests performed as part of routine assessments for an orbital wall fracture. The patient was a current smoker and did not show any respiratory symptoms.

Lung abscess by Actinomyces odontolyticus and Parvimonas micra co-infection presenting as acute respiratory failure: A case report.

Rationale: Actinomyces odontolyticus and Parvimonas micra are very rare causative organisms of lung abscess and acute respiratory failure.

Patient Concerns: A 49-year-old male patient visited the emergency room with a complaint of sudden onset of shortness of breath, and he developed acute respiratory failure rapidly.

Diagnosis: An abscess in the left lower lung field was diagnosed on the computed tomography scan of chest.

Validity of the GOLD 2017 classification in the prediction of mortality and respiratory hospitalization in patients with chronic obstructive pulmonary disease.

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) released an updated document in 2017 that excluded the spirometric parameter in the classification of patients. The validity of this new classification system in predicting mortality and respiratory hospitalization is still uncertain. Outpatients (n=149) with chronic obstructive pulmonary disease (COPD) who underwent spirometry and six-minutes walking test from October 2011 to September 2013 were enrolled.

Impact of coexistent chronic obstructive pulmonary disease on the survival of patients with small cell lung cancer receiving chemotherapy.

Background: While there is growing interest in the correlation between chronic obstructive pulmonary disease (COPD) and non-small cell lung cancer, very few studies have examined the interaction between COPD and small cell lung cancer (SCLC). Therefore, the aim of this study was to examine the impact of COPD on the survival of patients with SCLC.

Methods: The medical records of 110 patients with SCLC who received chemotherapy from July 2006 until April 2014 were retrospectively examined.

Usefulness of neutrophil to lymphocyte ratio in patients with chronic obstructive pulmonary disease: a prospective observational study.

Background/aims: Neutrophil to lymphocyte ratio (NLR) in peripheral blood is a useful systemic inflammatory response biomarker. However, NLR has not been studied in patients with chronic obstructive pulmonary disease (COPD). This study was aimed to evaluate the usefulness of NLR in patients with COPD.

Association between weight change and clinical outcomes in critically ill patients.

Purpose: Body weight fluctuates daily throughout a patient's stay in the intensive care unit (ICU) due to a variety of factors, including fluid balance, nutritional status, type of acute illness, and presence of comorbidities. This study investigated the association between change in body weight and clinical outcomes in critically ill patients during short-term hospitalization in the ICU.

Methods: All patients admitted to the Gyeongsang National University hospital between January 2010 and December 2011 who met the inclusion criteria of age 18 or above and ICU hospitalization for at least 2 days were prospectively enrolled in this study.
