1.Strengthening epidemiologic investigation of infectious diseases in Korea: lessons from the Middle East respiratory syndrome outbreak.
Journal of the Korean Medical Association 2015;58(8):706-713
The recent outbreak of Middle East respiratory syndrome (MERS) coronavirus infection in Korea resulted in large socioeconomic losses. This provoked the Korean government and the general public to recognize the importance of having a well-established system against infectious diseases. Although epidemiologic investigation is one of the most important aspects of prevention, it has been pointed out that much needs to be improved in Korea. We review here the current status of the Korean epidemiologic service and suggest possible supplementation measures. We examine the current national preventive infrastructure, including human resources such as Epidemic Intelligence Service officers, its governmental management, and related policies. In addition, we describe the practical application of these resources to the recent MERS outbreak and the progress in preventive measures. The spread of MERS demonstrated that the general readiness for emerging infectious diseases in Korea is considerably low. We believe that it is essential to increase society's investment in disease prevention. Fostering public health personnel, legislating management policies, and establishing research centers for emerging infectious diseases are potential solutions. Evaluating international preventive systems, developing cooperative measures, and initiating improvements are necessary. We evaluated the Korean epidemiologic investigation system and the public preventive measures against infectious diseases in light of the recent MERS outbreak. We suggest that governmental authorities in Korea enforce preventive policies, foster the development of highly qualified personnel, and increase investment in the public health domain of infectious disease prevention.

This case study explores the effectiveness of autologous cytokine-induced killer (CIK) cell-based immunotherapy in a 49-year-old male patient with inoperable stage IIIb cholangiocarcinoma, characterized by high levels of the sodium-dependent vitamin C transporter-2 (SVCT2) in immune cells. Despite an initial lack of tumor reduction following chemotherapy, the patient showed a significant decrease in tumor markers and stabilization of the tumor after undergoing radiation and proton therapy. Subsequently, CIK cell therapy, combined with high-dose vitamin C, was administered 52 times over 6 years. The patient’s tumor size reduced, and no cancer activity was detected for 7 years and 10 months post-diagnosis, indicating a successful long-term outcome without recurrence. This study suggests that CIK cell therapy, particularly in patients with elevated SVCT2 levels, may offer a promising adjuvant treatment for cholangiocarcinoma and potentially other cancers. Further research is needed to validate SVCT2 as a biomarker for the effectiveness of CIK cell therapy.

PURPOSE: We report a case of asymptomatic unexplained visual field loss diagnosed as early retinitis pigmentosa (RP) without pigmentation. CASE SUMMARY: A 33-year-old woman was referred to us with a constricted visual field (C24-2) before laser-assisted in-situ keratomileusis surgery. The visual field test (C30-2) revealed significantly decreased sensitivity between 15 to 25 degrees in both eyes. Close fundus examination revealed a subtle greyish retinal atrophic lesion along the vascular arcade and fluorescein angiography revealed a window defect in accordance with a retinal atrophic lesion in both eyes. Optical coherence tomography showed decreased retinal thickness around the macula. Electroretinogram revealed decreased b waves in rod response. Based on these findings, we diagnosed the patient with early RP without pigmentation. CONCLUSIONS: The possibility of early RP without pigmentation presenting as slight atrophy around the macula without significant pigmental degeneration should also be considered if a patient presents with peripheral visual field constriction without other symptoms. The ophthalmologist should ensure that the location of the visual field defect matches the location of the lesion. In addition, a detailed fundus examination with macular optical coherence tomography can be helpful to diagnose such a lesion.

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.
