1.Bronchiectasis.
Tuberculosis and Respiratory Diseases 2012;73(5):249-257
The frequency of diagnosing bronchiectasis is increasing around the world. Cystic fibrosis is the most common inherited cause of bronchiectasis, but there is increasing recognition of significant numbers of patients with bronchiectasis from various causes. With increasing awareness of bronchiectasis, a significant number of research, concerning the causes and treatments, were published over the past few years. Investigation of the underlying cause of bronchiectasis is the most important key to effective management. The purpose of this report is to review the immunological abnormalities that cause bronchiectasis in those that the cystic fibrosis has been excluded, identify the available evidences of current management, and discuss several controversies in the treatment of this disorder.

Hepatocellular carcinoma (HCC) is a highly lethal cancer with limited treatment options and poor prognosis. Carbon ion radiotherapy (CIRT) has emerged as a promising treatment modality for HCC due to its unique physical and biological properties. CIRT uses carbon ions to target and destroy cancer cells with a high precision and efficacy. The Bragg Peak phenomenon allows precise dose delivery to the tumor while minimizing damage to healthy tissues. In addition, the high relative biological effectiveness of carbon ions can be shown against radioresistant and hypoxic tumor areas. CIRT also offers a shorter treatment schedule than conventional radiotherapy, which increases patient convenience and compliance. The clinical outcomes of CIRT for HCC have shown excellent local control rates with minimal side effects. Considering its physical and biological properties, CIRT may be a viable option for complex clinical scenarios such as patients with poor liver function, large tumors, re-irradiation cases, and tumors close to critical organs. Further research and larger studies are needed to establish definitive indications for CIRT and to compare its efficacy with that of other treatment modalities. Nevertheless, CIRT offers a potential breakthrough in HCC management, providing hope for improved therapeutic outcomes and reduced treatment-related toxicities.

Hepatopulmonary syndrome (HPS) is characterized by a defect in arterial oxygenation that's induced by pulmonary vascular dilatation in the setting of liver disease. Some studies have shown the relationship between the presence of the HPS and the severity of liver disease, but there are only rare cases of HPS inpatient with Child-Pugh class A liver cirrhosis. We report here on a case of a 58 years-old male who suffered from progressive dyspnea for the previous few years. He was diagnosed with alcoholic liver cirrhosis 5 years previously. There was no significant abnormality on the chest radiograph and transthoracic echocardiography, but the arterial blood gas analysis revealed severe hypoxemia. Contrast-enhanced transesophageal echocardiograpy with agitated saline demonstrated a delayed appearance of microbubbles in the left cardiac chambers. Thus, he was finally diagnosed with HPS. This case suggests that we should consider HPS when a patient with compensated liver cirrhosis has unexplained dyspnea.

OBJECTIVES: Purpose of this study is investigation the influence of intravenous and oral bisphosphonate to bone union and clinical results in patient treated with plate fixation in an osteoporotic distal radius fracture. MATERIALS AND METHODS: The medical records of 160 patients with an osteoporotic distal radius fracture treated with plate fixation in our hospital between January 2008 and April 2012 were reviewed retrospectively. The patients were classified by 3 groups; who did not administrate bisphosphonate after surgery as Group I (n=69), administrated oral bisphosphonate after surgery as Group II (n=44), and administrated intravenous bisphosphonate as Group III (n=47). After surgery, bone union, radiologic parameters, disabilities of the DASH score and range of motion of wrist were assessed. RESULTS: Mean time of bone union was 6.7 weeks in Group I, 6.8 weeks in Group II, and 7.1 weeks in Group III. There was no significant difference between three groups (P=0.571). Bone union rate on 6weeks shows no significant differences between three groups (P=0.16). Three groups also have no significant differences in all radiologic and clinical parameters. CONCLUSION: This study shows that early initiation of oral and Intravenous bisphosphonate did not affect bone union and clinical results compared to group who did not administrate bisphosphonate result in patient treated with plate fixation in an osteoporotic distal radius fracture.

5.Pharmacotherapy for pulmonary arterial hypertension.
Journal of the Korean Medical Association 2011;54(12):1299-1305
Although pulmonary arterial hypertension (PAH) is an orphan disease with high mortality and for which there is no cure, current treatment have led to considerable gains in the outcomes of these patients. Oral anticoagulation is proposed for most patients; diuretic treatment and supplemental oxygen are indicated in cases of fluid retention and hypoxemia. High doses of calcium-channel blockers are indicated only in the minority of patients who respond to acute vasoreactivity testing. Nonresponders to acute vaoreactivity testing or who remain in World Health Organization (WHO) functional class III, should be considered candidates for treatment with either an oral phophodiesterase-5 inhibitor or an oral endothelin-receptor antagonist. Continuous intravenous administration of epoprostenol remains the treatment of choice in WHO functional class IV patients. Combination therapy is recommended for patients treated with PAH monotherapy who remain in WHO functional class III. The pharmacologic management of PAH is rapidly evolving as newer therapeutic targets that stabilize or reverse pulmonary vascular disease and as clinical practice pattern shift in favor of earlier diagnosis and aggressive treatment. Questions about preferred first-line therapy and when to institute combination therapies remain. Future drug development targeting other molecular pathways of PAH is essential for definitively improving patient survival. The search for novel treatment continues, with promising new concepts arising from a better understanding of the pathobiology of PAH.

The ongoing coronavirus disease 2019 (COVID-19) pandemic is causing tremendous damage globally. The Republic of Korea (ROK), a highly export-dependent nation, is a leader in the fight against the COVID-19 pandemic and coping well with the disaster. Like the drivethrough COVID-19 testing, which reflects the brilliant flexibility of the Korean medical system, onsite mass workplace testing for COVID-19, which our hospital has been performing over the past few months, is a unique and valuable countermeasure. We believe it is time that the current health examination system for workers in the ROK considered the risk of transmissible diseases.

Propionibacterium acnes is one of the commensals living on the human skin and glands, implicated mainly in acnes, but seldom in deep infection. Pleural empyema is rarely complicated with closed thoracostomy. We experienced 1 case of empyema caused by P. acnes after pleural biopsy and closed thoracostomy through a percutaneous pigtail catheter. A 79-year-old man was admitted for cough, purulent sputum and shortness of breath. Three weeks ago, closed thoracostomy and pleural biopsy were performed to confirm a diagnosis for his recurrent pleural effusion. He had increased amount of right pleural effusion. Through the pigtail catheter, pleural effusion was removed. Gram-positive rods were observed in Gram stain, but not cultured. By 16S rRNA analysis, P. acnes was confirmed as the pathogen. His empyema was repeatedly treated with antibiotics, fibrolysis and irrigation. Pleural decortication was recommended. We report the first case of empyema with P. acnes in Korea, possibly complicated with closed thoracostomy procedures.

Objective:
The vulnerable and frail elderly individuals are at a compounded risk of worsening, rather than recovering, from external stress such as sepsis. Ambulation is majorly considered as a phenotype and determining factor of frailty. This study was undertaken to determine whether inability of ambulation is predictive for the prognosis of elderly patients afflicted with sepsis.
Methods:
Data were collected retrospectively from the medical records of an emergency medical center, from 1 November 2016 to 28 February 2017. Patients older than 65 years, who underwent blood culture or with a diagnosis of sepsis or septic shock and with Sequential Organ Failure Assessment (SOFA) score above 2 points, were included in the study. The predictive ability of the clinical factors was analyzed by comparing with the primary outcome of in-hospital mortality.
Results:
A total of 105 patients were included in the study; 58 (55.2%) male and 47 (44.8%) female patients, with median age 78 years (range, 65-96 years). Of these, 89 (84.8%) patients were independently ambulatory before presentation. The median SOFA score was 3 (2-12), and 20 (19%) patients had expired in the hospital. Logistic regression revealed that inability of ambulation is not predictive of mortality (odds ratio, 0.872; 95% confidence Interval, 0.176-4.309; P=0.866). However, correlation analysis with the SOFA score revealed an association with inability of ambulation (r=0.277, P=0.004), and multiple regression analysis also showed that ambulation affects the SOFA score (t=2.435, P=0.017; t=-2.521, P=0.013).
Conclusion
Inability of ambulation does not predict in-hospital mortality, but affects the SOFA score of elderly patients afflicted with sepsis or in septic shock.
