Purpose: This descriptive study investigated the effects of nurses’ knowledge of withdrawalof life-sustaining treatment, death anxiety, and perceptions of hospice care on their attitudes toward withdrawal of life-sustaining treatment. Methods: Data were collected from 262 nurses at tertiary hospitals, general hospitals, or primary hospitals in Busan, Korea, and statistically analyzed using the t-test, analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical regression analysis. Results: The participants’ scores were 3.68±0.45 (out of 5) for attitudes toward withdrawal of life-sustaining treatment, 0.65± 0.15 (out of 1) for knowledge of withdrawal of life-sustaining treatment, 2.61±0.26 (out of 4) for death anxiety, and 4.06±0.43 (out of 5) for perceptions of hospice care. Furthermore, knowledge of withdrawal of life-sustaining treatment and perceptions of hospice care showed positive correlations with attitudes toward withdrawal of life-sustaining treatment, while death anxiety showed a negative correlation. The most significant factors influencing attitudes toward withdrawal of life-sustaining treatment were perceptions of hospice care, followed by having experienced caring for patients who withdrew life-sustaining treatment, death anxiety, having a spouse, and ethical values, and the overall explanatory power was 43.0%. Conclusion This study showed that perceptions of hospice were an important fac-tor influencing nurses’ attitudes toward withdrawal of life-sustaining treatment. Therefore,it is necessary to develop and validate educational intervention programs that can improve perceptions of hospice care.

Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-year-old woman suffering from buttock pain due to breast cancer metastases in the SI joint. We treated this patient with PRF neuromodulation of the L4-S3 primary dorsal rami and lateral branches using a rotating curved needle technique. The patient tolerated the procedures well, without any complications. She experienced about 70% reduction in pain, and pain relief was sustained for 10 months. This result suggests that PRF neuromodulation is a safe, effective treatment for pain from SI joint metastases.

OBJECTIVES: Catecholamine metabolism has been thought to be related to the pathophysiology of panic disorder. There are two human COMT alleles, coding for a low activity enzyme, COMT L(L), and a high activity enzyme, COMT H(H), respectively. We examined the distribution of COMT genotypes and the relationship between COMT genetic polymorphism and some clinical characteristics in patients with panic disorder. METHOD: We recruited 51 patients who met the DSM-IV criteria for panic disorder, and 45 normal control subjects who had neither medical nor psychiatric illnesses. Genetic polymorphism of COMT was identified in all subjects using PCR-based restriction fragment length polymorphism(RFLP) analysis. We assessed some clinical variables including treatment responses in panic patients and measured anxiety and depression levels in normal control subjects using Spielberger State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI). RESULT: The frequency of the homozygous LL genotype was higher in panic patients than that in control subjects (19.6% vs. 2.2%). We found that panic disorder was significantly associated with L allele (x2=8.66, p=0.003) and LL genotype(x2=8.45, p=0.015). Panic patients with LL genotype showed poorer treatment response than those with other genotypes (F=4.98, p=0.011). CONCLUSION: These results suggest that LL genotype of the COMT gene may be related to the pathophysiology and clinical courses in some patients with panic disorder.

Lymphangioma of the esophagus is a rare submucosal benign tumor. A 49-year-old man was referred because of a foreign body sensation in the esophagus. In endoscopy, a 10.0×1.0-cm longitudinal, translucent, whitish yellow mass covered with normal esophageal mucosa was found in the lower esophagus. Endoscopic ultrasonography revealed a heterogeneous, mainly hypoechoic, well-circumscribed lesion located in the third layer. Incisional biopsy was performed, and histologic findings showed multiple dilated lymphatic vessels, consistent with lymphangioma. After 3 months of proton pump inhibitor treatment, the symptom was relieved and the patient is currently asymptomatic and under surveillance.

Primary sternal osteomyelitis (PSO) is a rare condition that may develop without any contiguous focus of infection. Due to the rarity of the disease, early diagnosis and appropriate treatment are often delayed. Herein, we describe a patient with PSO caused by Staphylococcus aureus that presented with chest pain and fever. The patient had no predisposing factors for sternal osteomyelitis. The chest pain was thought to be non-cardiogenic, as electrocardiography and cardiac enzyme did not reveal ischemic changes when he visited the emergency room. After blood culture revealed the presence of S. aureus, every effort was made to identify the primary focus of infection. Bone scan and magnetic resonance imaging revealed osteomyelitis with soft tissue inflammation around the sternum. After 8 weeks of antibiotics treatment, the patient recovered without any complications.

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by progressive fibrosis and destruction of intra- and extrahepatic bile ducts resulting in hepatic failure and death. Only the liver transplantation is the possible treatment for patients to survive. There has been a few reports that steroid is an effective treatment in autoimmune variant sclerosing cholangitis, which is thought to be a familial diseases with different etiology, and steroid responsive biliary strictures be named as immunoglobulin G4 (IgG4)-associated cholangitis (IAC). There is no reliable data regarding effective steroid treatment in autoimmue variant sclerosing cholangitis in Korea. We report a case of 32-year-old male with sclerosing cholangitis, who was diagnosed by endoscopic retrograde cholangiopancreatography (ERCP) and liver biopsy, showing favorable response to prednisolone therapy.

Inflammatory pseudotumor is an uncommon mass which develops most frequently in the lung of young adults. It is characterized by localized fibrous proliferations with chronic inflammatory cell infiltration. Due to its rarity and similarity in radiologic appearance with malignant hepatic tumors, hepatic inflammatory pseudotumor (HIPT) is often misdiagnosed and resected accidentally. We report a case of HIPT which was unnecessarily resected due to synchronous small peripheral cholangiocarcinoma located on the other segment of liver.

Orphan nuclear receptor estrogen-related receptor γ (ERRγ) regulates cell growth and tumorigenesis in various cancers. However, the clinical relevance of ERRγ to hepatocellular carcinoma (HCC) remains unclear. Here we examined the clinical significance of ERRγ in HCC and its potential as a therapeutic target. ERRγ levels in tissues from completely resected specimens from 190 HCC patients were examined immunohistochemically and their association with clinical stage and pathological grade was analyzed. Small interfering RNA (siRNA)-mediated knockdown of ERRγ (siRNA-ERRγ) or an ERRγ inverse agonist, GSK5182, were also used to examine the effects of ERRγ inhibition on the proliferation and growth of a human hepatoma cell line, PLC/PRF/5. Immunohistochemical analysis revealed that tumor tissues showed higher levels of ERRγ-positivity than adjacent non-tumor lesions. Tumors showing high levels of ERRγ immunoreactivity also had advanced tumor node metastasis (TNM) and Barcelona Clinic Liver Cancer stages and a higher Edmondson–Steiner grade. In addition, high-level expression of ERRγ in tumors of advanced TNM stage correlated with poorer overall survival. Treatment of PLC/PRF/5 cells with siRNA-ERRγ or GSK5182 inhibited proliferation through G1 arrest, increased expression of p21 and p27 and decreased expression of phosphorylated retinoblastoma protein. GSK5182-induced reactive oxygen species also suppressed the proliferation of PLC/PRF/5 cells. The present study showed that ERRγ expression is clinically significant in HCC; therefore, it can be considered a biomarker for HCC diagnosis. Moreover, the results provide a rationale for the use of ERRγ inhibitors such as GSK5182 as potential therapeutic agents.

Hepatic tuberculosis (TB) is usually associated with pulmonary or miliary TB, but primary hepatic TB is rare less than 1% of all cases of TB. Because hepatic TB lacks typical clinical manifestations as well as typical imaging findings, it is difficult to differentiate TB from the malignancies such as hepatic metastasis, intrahepatic cholangiocarcinoma and hepatocellular carcinoma. A 76-year-old woman was presented with single liver mass detected on routine examination. She was clinically diagnosed with hepatocellular carcinoma and underwent surgical excision of the lesion. However, histologic examination revealed caseous necrotizing granuloma and the PCR test for Myco-bacterium tuberculosis was positive. The final diagnosis was primary hepatic TB. Here we report the case with primary hepatic TB who was initially misdiagnosed with hepatocellular carcinoma and underwent surgical excision.
