Granulomatous hypophysitis is a rare pituitary condition that commonly presents with enlargement of the pituitary gland. A 31-year-old woman was admitted to the hospital with a severe headache and bitemporal hemianopsia. Magnetic resonance imaging (MRI) showed an 18 x 10-mm sellar mass with suprasellar extension and compression of the optic chiasm. Interestingly, brain MRI had shown no abnormal finding 4 months previously. On hormonal examination, hypopituitarism with mild hyperprolactinemia was noted. The biopsy revealed granulomatous changes with multinucleated giant cells. We herein report this rare case and discuss the relevant literature.

Cardiotoxicity associated with 5-fluorouracil (FU) is an uncommon, but potentially lethal, condition. The case of an 83-year-old man with colon cancer who developed chest pain during 5-FU infusion is presented. The electrocardiogram (ECG) showed pronounced ST elevation in the lateral leads, and the chest pain was resolved after infusion of nitroglycerin. A coronary angiogram (CAG) revealed that the patient had significant atherosclerosis in the proximal left circumflex artery. Coronary artery spasm with fixed stenosis was considered, and a drug-eluting stent was implanted. After 8 hours, the patient complained of recurring chest pain, paralleled by ST elevation on the ECG. The chest pain subsided after administration of intravenous nitroglycerin followed by sublingual nifedipine. Repeated CAG showed patency of the previous stent. This case supports the vasospastic hypothesis of 5-FU cardiac toxicity, indicating that a calcium channel blocker may be effective in the prevention or treatment of 5-FU cardiotoxicity.

The Korean Journal of Internal Medicine.2012;27(3):338-341. doi:10.3904/kjim.2012.27.3.338

There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

Interleukin-6 -634 C/G and -174 G/C Polymorphisms in Korean Patients Undergoing Hemodialysis.

Jung Hwa RYU ; Seung Jung KIM

The Korean Journal of Internal Medicine.2012;27(3):327-337. doi:10.3904/kjim.2012.27.3.327

BACKGROUND/AIMS: Chronic inflammatory status is a possible risk factor for vascular access dysfunction in hemodialysis (HD) patients, but susceptibility differences appear among individuals. Interleukin (IL)-6 is a well-known inflammatory cytokine with various polymorphisms. We examined whether IL-6 polymorphisms are associated with vascular access dysfunction in HD patients. METHODS: A total of 80 HD patients (including 42 diabetic patients) were enrolled. Polymorphisms in the IL-6 gene promoter (-634 C/G and -174 G/C) were studied using restriction length polymorphism polymerase chain reaction analysis. Vascular access patency was compared between the patient groups with respect to IL-6 polymorphisms. An additional 89 healthy individuals were enrolled in the control group. Plasma IL-6 levels were de termined by enzyme-linked immunosorbent assay. RESULTS: The GG genotype and G allele at position -634 in the IL-6 promoter were more frequently observed in HD patients than in controls. Furthermore, the distribution of the -634 polymorphism differed according to vascular access patency in non-diabetic HD patients. However, the G allele was not a significant risk factor for early access failure. No significant association appeared between the IL-6 -634 C/G polymorphism and plasma IL-6 levels. The C allele of the IL-6 -174 G/C polymorphism was not detected in our study population. CONCLUSIONS: The IL-6 -634 G allele appears with greater frequently in patients with end-stage renal disease and may be associated with vascular access dysfunction in non-diabetic HD patients.

The Korean Journal of Internal Medicine.2012;27(3):317-326. doi:10.3904/kjim.2012.27.3.317

BACKGROUND/AIMS: The clinical implications of hypocholesterolemia have not been well studied, although some studies have revealed an association between hypocholesterolemia and intracerebral hemorrhage (ICH). We evaluated the clinical characteristics of subjects with very low-density lipoprotein cholesterol (LDL-C) and compared the risk for ICH using various clinical parameters. METHODS: Using hospital records, we evaluated the clinical characteristics of subjects with LDL-C levels < or = 40 mg/dL (very low LDL-C group). We also evaluated the risk for ICH in this very low LDL-C group and in subjects with low LDL-C < or = 70 mg/dL (low LDL-C group). RESULTS: Among 34,415 subjects who presented at the laboratory for serum LDL-C measurements, 250 subjects had a very low serum LDL-C level (< or = 40 mg/dL). About half of the subjects were statin users; the very low LDL levels in the other subjects were likely attributable to alcohol consumption or a various chronic illness such as liver disease or end-stage renal disease (ESRD). ICH occurred in three subjects with very low LDL-C, all of whom had no history of statin use. ESRD tended to be associated with ICH in subjects with serum LDL-C < or = 70 mg/dL. CONCLUSIONS: About 1% of the subjects whose LDL-C was measured in the hospital had a LDL-C level < or = 40 mg/dL, and about half of these subjects had no history of hypolipidemic therapy. ICH incidence was not related to LDL-C level or statin use.

The Korean Journal of Internal Medicine.2012;27(3):311-316. doi:10.3904/kjim.2012.27.3.311

BACKGROUND/AIMS: Home oxygen therapy (HOT) costs a great deal every year and demand for the service is growing. In Korea, health insurance has covered HOT since November 1, 2006. The objective of this study was to evaluate clinical features of patients who used long-term HOT due to chronic respiratory failure and to determine the appropriateness of oxygen prescriptions. METHODS: Between November 2006 and April 2010, patients prescribed long-term HOT were enrolled in the study at a tertiary university referral hospital and their medical records and telephone survey information were evaluated. In total, 340 patients were evaluated retrospectively. RESULTS: Regarding the initial indications for HOT, their mean PaO2 was 49.8 mmHg and mean SpO2 was 82.2%. Underlying diseases included chronic obstructive pulmonary disease (COPD, 19.8%), lung cancer (12.6%), and interstitial lung disease (11.2%). The admission rate within 1 year was 53.4% and the average number of admissions was 1.64/patient. Other underlying diseases for which oxygen was prescribed, despite not meeting the insurance coverage criteria, were lung cancer (36.6%) and interstitial pneumonia (16.6%). CONCLUSIONS: Home oxygen prescriptions have increased since health insurance coverage was extended. However, cases of oxygen prescriptions frequently do not meet the coverage criteria. It is important to discuss extending the coverage criteria to other disease groups, such as interstitial lung disease and lung cancer, in terms of cost-effectiveness. Further, physicians prescribing oxygen therapy should be educated regarding the criteria.

Plasma N-Terminal Pro-B-Type Natriuretic Peptide Is Predictive of Perioperative Cardiac Events in Patients Undergoing Vascular Surgery.

Ji Hyun YANG ; Jin Ho CHOI ; Young Wook KI ; Dong Ik KIM ; Duk Kyung KIM ; Jeong Rang PARK ; Jae K OH ; Seung Hyuk CHOI

The Korean Journal of Internal Medicine.2012;27(3):301-310. doi:10.3904/kjim.2012.27.3.301

BACKGROUND/AIMS: Identification of patients at high risk for perioperative cardiac events (POCE) is clinically important. This study aimed to determine whether preoperative measurement of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) could predict POCE, and compared its predictive value with that of conventional cardiac risk factors and stress thallium scans in patients undergoing vascular surgery. METHODS: Patients scheduled for non-cardiac vascular surgery were prospectively enrolled. Clinical risk factors were identified, and NT-proBNP levels and stress thallium scans were obtained. POCE was the composite of acute myocardial infarction, congestive heart failure including acute pulmonary edema, and primary cardiac death within 5 days after surgery. A modified Revised Cardiac Risk Index (RCRI) was proposed and compared with NT-proBNP; a positive result for ischemia and a significant perfusion defect (> or = 3 walls, moderate to severely decreased, reversible perfusion defect) on the thallium scan were added to the RCRI. RESULTS: A total of 365 patients (91% males) with a mean age of 67 years had a median NT-proBNP level of 105.1 pg/mL (range of quartile, 50.9 to 301.9). POCE occurred in 49 (13.4%) patients. After adjustment for confounders, an NT-proBNP level of > 302 pg/mL (odds ratio [OR], 5.7; 95% confidence interval [CI], 3.1 to 10.3; p < 0.001) and a high risk by the modified RCRI (OR, 3.9; 95% CI, 1.6 to 9.3; p = 0.002) were independent predictors for POCE. Comparison of the area under the curves for predicting POCE showed no statistical differences between NT-proBNP and RCRI. CONCLUSIONS: Preoperative measurement of NT-proBNP provides information useful for prediction of POCE as a single parameter in high-risk patients undergoing noncardiac vascular surgery.

Hoyoung LEE ; Sul Hee YI ; Mi Seon SEO ; Jin Nam HYUN ; Jin Seok JEON ; Hyunjin NOH ; Dong Cheol HAN ; Seung Duk HWANG ; So Young JIN ; Soon Hyo KWON

The Korean Journal of Internal Medicine.2012;27(3):293-300. doi:10.3904/kjim.2012.27.3.293

BACKGROUND/AIMS: The recently published Oxford classification of IgA nephropathy (IgAN) proposed a split system for histological grading, based on prognostic pathological features. This new classification system must be validated in a variety of cohorts. We investigated whether these pathological features were applicable to an adult Korean population. METHODS: In total, 69 adult Korean patients with IgAN were analyzed using the Oxford classification system at Soonchunhyang University Hospital, Seoul, Korea. All cases were categorized according to Lee's classification. Renal biopsies from all patients were scored by a pathologist who was blinded to the clinical data for pathological variables. Inclusion criteria were age greater than 18 years and at least 36 months of follow-up. We excluded cases with secondary IgAN, diabetic nephropathy combined other glomerulopathies, less than 36 months of follow-up, and those that progressed rapidly. RESULTS: The median age of the patients was 34 years (range, 27 to 45). Mean arterial blood pressure was 97 +/- 10 mmHg at the time of biopsy. The median follow-up period was 85 months (range, 60 to 114). Kaplan-Meier analysis showed significant prognostic predictions for M, E, and T lesions. A Cox proportional hazard regression analysis also revealed prognostic predictions for E and T lesions. CONCLUSIONS: Using the Oxford classification in IgAN, E, and T lesions predicted renal outcome in Korean adults after taking clinical variables into account.

Jin Ook CHUNG ; Dong Hyeok CHO ; Dong Jin CHUNG ; Min Young CHUNG

The Korean Journal of Internal Medicine.2012;27(3):285-292. doi:10.3904/kjim.2012.27.3.285

BACKGROUND/AIMS: Many studies have demonstrated an association between hemoglobin levels and cardiovascular disease in diabetic patients. The aim of this study was to determine whether there is an association between hemoglobin concentrations and various clinical parameters, including metabolic factors, plasma C-peptide response after a meal tolerance test, and microvascular complications, in Korean patients with type 2 diabetes. METHODS: In total, 337 male patients with type 2 diabetes were recruited. All subjects were subjected to a meal tolerance test and underwent assessment of hemoglobin levels, fasting and postprandial beta-cell responsiveness, and microvascular complications. RESULTS: Patients with lower hemoglobin concentrations had a longer duration of diabetes, a lower body mass index, and lower concentrations of total cholesterol, triglycerides, and low-density lipoprotein cholesterol. They also had lower levels of postprandial C-peptide, Delta C-peptide, and postprandial beta-cell responsiveness. They had a higher prevalence of retinopathy and nephropathy. In multivariate analyses, there was a significant association between nephropathy and hemoglobin concentration. Also, hemoglobin concentrations were independently associated with Delta C-peptide levels and postprandial beta-cell responsiveness. CONCLUSIONS: Hemoglobin concentrations are associated with postprandial C-peptide responses and diabetic nephropathy in patients with type 2 diabetes.

Hyeon Young YOON ; Young Koog CHEON ; Hye Jin CHOI ; Chan Sup SHIM

The Korean Journal of Internal Medicine.2012;27(3):278-284. doi:10.3904/kjim.2012.27.3.278

BACKGROUND/AIMS: The aim of this non-randomized study was to determine the role of photodynamic therapy (PDT) in a multimodal approach for the palliation of advanced esophageal carcinoma. METHODS: Twenty consecutive patients with obstructing esophageal cancer were enrolled in this study. Each subject had dysphagia, and nine could not swallow fluid. External beam radiotherapy or a self-expandable metal stent was used following PDT for dysphagia due to recurrence of the malignancy. RESULTS: At 4 weeks post-PDT, a significant improvement in the dysphagia score was observed in 90% of patients, from 2.75 +/- 0.91 to 1.05 +/- 0.83 (p < 0.05). Patients with recurrent dysphagia underwent stent insertion at an average of 63 days (range, 37 to 90). The rate of major complications was 10%. Two esophageal strictures occurred, which were treated by placement of a modified expandable stent across the stricture. The median survival in these cases was 7.0 +/- 0.6 months. One patient that was treated with PDT and radiotherapy is alive and showed a complete tumor response. CONCLUSIONS: PDT as a multimodality treatment is safe and effective for relieving malignant esophageal obstruction with minimal complications.
