Epidemiology of Femoroacetabular Impingement in Korea.

Background: Femoroacetabular impingement (FAI) is increasingly recognized as a significant cause of hip and groin pain. Despite the rising awareness, epidemiological data on FAI remain limited in East Asia. This study aimed to investigate the prevalence, treatment patterns, and associated medical costs of FAI in South Korea.

Causes of Reoperations After Primary Total Hip Arthroplasty: A Retrospective Cohort Study Over 20 Years.

Background: Reoperations following total hip arthroplasty (THA) remain a major clinical challenge, with their incidence and socioeconomic burden rising despite advances in surgical techniques and prosthesis design. This study aimed to evaluate the predominant causes of reoperations following THA over two decades at a tertiary referral hospital, comparing trends between 2004 to 2013 and 2014 to 2023.

Methods: We analyzed all reoperations performed at a tertiary referral hospital between January 2004 and December 2023.

Predictive Value of Procalcitonin for Bacterial Infection after Transarterial Chemoembolization or Radiofrequency Ablation for Hepatocellular Carcinoma.

This prospective observational study aimed at investigating the role of procalcitonin (PCT) in diagnosing bacterial infection and guiding antibiotic therapy for hepatocellular carcinoma (HCC) patients with fever after transarterial chemoembolization (TACE) and/or radiofrequency ablation (RFA). Ninety-seven cases (84 patients) were enrolled. Serum PCT, C-reactive protein (CRP), and white blood cell (WBC) counts were measured on the day of fever onset (day 0) and days 1, 3, 5, and 7 of fever.

Active surveillance for carbapenem-resistant Acinetobacter baumannii in a medical intensive care unit: Can it predict and reduce subsequent infections and the use of colistin?

Background: Infection caused by carbapenem-resistant Acinetobacter baumannii (CRAB) has become a major problem in intensive care units (ICUs), with high incidence and mortality. This prospective study investigated the diagnostic value and influence of active surveillance, followed by isolation and enhanced contact precaution (IECP), on the subsequent CRAB infection and colistin use.

Methods: The study prospectively enrolled 1,115 patients who were admitted to the medical ICU of Chonnam National University Hwasun Hospital between April 2011 and November 2014.

Predictors of viral pneumonia in patients with community-acquired pneumonia.

Background: Viruses are increasingly recognized as major causes of community-acquired pneumonia (CAP). Few studies have investigated the clinical predictors of viral pneumonia, and the results have been inconsistent. In this study, the clinical predictors of viral pneumonia were investigated in terms of their utility as indicators for viral pneumonia in patients with CAP.

Update on the Epidemiology, Treatment, and Outcomes of Carbapenem-resistant Acinetobacter infections.

Carbapenem-resistant Acinetobacter species are increasingly recognized as major nosocomial pathogens, especially in patients with critical illnesses or in intensive care. The ability of these organisms to accumulate diverse mechanisms of resistance limits the available therapeutic agents, makes the infection difficult to treat, and is associated with a greater risk of death. In this review, we provide an update on the epidemiology, resistance mechanisms, infection control measures, treatment, and outcomes of carbapenem-resistant Acinetobacter infections.

Hypoparathyroidism and subclinical hypothyroidism with secondary hemochromatosis.

Hemochromatosis is an inherited genetic disorder of iron metabolism which can also occur as a secondary result of iron-overload. It leads to organ damage such as cardiomyopathy, liver cirrhosis, hypogonadism, and diabetes. This paper discusses a case of secondary hemochromatosis associated with repeated transfusions, presenting as asymptomatic hypoparathyroidism and subclinical hypothyroidism with multiple organ involvement.

Was 2009 Pandemic Influenza A (H1N1) Mild Among Pregnant Korean Women?

Clinical and laboratory data from Western countries suggest that pregnant women are at an increased risk for severe illness and complications associated with 2009 pandemic influenza A (H1N1). However, previous data among Korean women suggested a less severe outcome. In this study performed at a single referral center in Korea, rates of admission, pneumonia, intensive care unit admission, and death related to 2009 pandemic influenza A (H1N1) were significantly higher in 33 pregnant women than in 723 nonpregnant women of reproductive age (p<0.

Clinical experience of raltegravir with abacavir/lamivudine or zidovudine/lamivudine in HIV-infected Korean adults.

The efficacy and safety of raltegravir (RAL) with tenofovir (TDF)/emtricitabine (FTC) have been well studied in human immunodeficiency virus (HIV)-infected patients. However, limited clinical data are available on the use of RAL with abacavir (ABC)/lamivudine (3TC) or zidovudine (ZDV)/3TC. We investigated HIV-1-infected Korean adults, including 13 antiretroviral-naïve patients and 15 antiretroviral-experienced patients, treated with RAL plus ABC/3TC or ZDV/3TC.

Plain radiograph fails to reflect the alignment and advantages of navigation in total knee arthroplasty.

The study purposed to determine if a navigation in total knee arthroplasty (TKA) leads to accurate limb alignment and component position than the conventional technique as measured by full length standing radiographs and to evaluate the correlation between navigation and radiographic measurements. A total of 160 knees underwent navigation (n = 80) or conventional (n = 80) TKAs. The frontal femoral alignment was more accurate in navigation TKAs, whereas mechanical axis and frontal tibial alignment were similar in both techniques.
