BACKGROUND/AIMS: Improvements in dialysis therapies and patient care are leading to more patients receiving dialysis for longer periods of time. Survival rates with peritoneal dialysis (PD) are superior to those with hemodialysis (HD) during the initial 2-3 years; however, data comparing the outcomes of these two methods are lacking. Thus, we performed a retrospective study of patients treated with dialysis for longer than 3 years to investigate patient condition according to mode of dialysis. METHODS: A total of 80 patients currently being treated by dialysis for at least 36 months at the Eulji Medical Center were included in this study. Patients' laboratory data and admissions histories over the prior 3 years were reviewed. Dialysis adequacy, body composition, and cytokine levels were quantified. RESULTS: A total of 39 PD and 41 HD patients, with no difference in mean age or gender, were compared. Regarding dialysis adequacy, 97.5% of HD patients met the criterion of 1.2 Kt/V or higher, whereas only 58% of PD patients satisfied the required weekly Kt/V of 1.7. Inflammatory cytokines were significantly elevated in PD patients; however, PD patients with adequate dialysis expressed the same inflammatory cytokines as HD patients. CONCLUSIONS: The delivery of adequate dialysis to PD patients over extended periods of time is difficult. Thus, more rigorous management of PD patients is required to avoid insufficient dialysis and inflammation.

Anemia is a common and significant complication of chronic kidney disease (CKD). However, its prevalence and current management status has not been studied thoroughly in Korea. We examined the prevalence of anemia, its association with clinical and laboratory factors, and utilization of iron agents and erythropoiesis stimulating agents using the baseline data from the large-scale CKD cohort in Korea. We defined anemia when hemoglobin level was lower than 13.0 g/dL in males and 12.0 g/dL in females, or received by erythropoiesis stimulating agents. Overall prevalence of anemia was 45.0% among 2,198 non-dialysis CKD patients from stage 1 to 5. Diabetic nephropathy (DN) as a cause, CKD stages, body mass index (BMI), smoking, leukocyte count, serum albumin, iron markers, calcium, and phosphorus concentration were identified as independent risk factors for anemia. Considering the current coverage of Korean National Health Insurance System, only 7.9% among applicable patients were managed by intravenous iron agents, and 42.7% were managed by erythropoiesis stimulating agents.

Ischemic colitis is generally considered a disease of the elderly. The causes of ischemic colitis include low-flow states due to cardiac dysfunction or hypovolemia and certain medications including estrogen. Here we report a case of ischemic colitis in a 26-year-old woman. She had no specific medical history except taking oral-contraceptives for a long time. The mechanism of estrogen-induced ischemic colitis is not clearly understood. But we recommend that oral-contraceptives should be considered as a cause of ischemic colitis in young women.

Foreign bodies in the upper esophagus should be removed as soon as possible to avoid serious complications. These foreign bodies can penetrate the bowel wall and cause severe complications. The peristalsis of the esophagus is not strong enough to prevent it from retaining swallowed objects. Hence, perforation from a foreign body is more likely to occur in the esophagus than in the rest of the gastrointestinal tract. A razor blade is a rare foreign body of the esophagus. Its sharpness and large size make it difficult to remove. A razor blade was very firmly impacted in the esophageal wall in our case, and the razor blade had not moved from the upper esophagus. A standard overtube has limitations to remove a razor blade inside the overtube's lumen. We report here on a case of using a wedge resected overtube made it possible to successfully extract a razor blade and no serious complications occurred after extraction of the razor blade.

Pneumatosis cystoides intestinalis is a rare condition characterized by gas-filled cysts within the bowel wall. It may be idiopathic or secondary to a variety of disorders. Associated conditions include chronic obstructive pulmonary disease, the use of non-steroidal anti-inflammatory drugs, collagen vascular disease, organ transplantation, and necrotizing enterocolitis. Approximately 15% of cases are idiopathic. We present a case of pneumatosis cystoides intestinalis complicated by pneumoperitoneum in chronic respiratory failure due to a post-tuberculosis destroyed lung. Successful palliation involved paracentesis of the peritoneal air and oxygen therapy.

Break of a stent delivery catheter and subsequent stent loss (SL) has been a rare event in the drug-eluting stent (DES) era. We here report a case of successful retrieval of a stent after a break if the delivery catheter and SL from a balloon catheter at a culprit lesion. We finally resolved this situation using a simple balloon technique for both the broken stent catheter inside of the guide catheter and the unexpanded stent in the culprit lesion. Thus balloons are an important weapon in our armamentarium in the cardiac catheterization laboratory for urgent retrieval of a lost stent. Their apt use definitely allowed our patient to avoid undergoing emergency cardiovascular thoracic surgery.

Lipomas are common soft tissue tumors that are located in the body tissues containing adipose tissues. However, lipomas arising from the walls of a vein are very rare. Intravascular lipomas have been described most commonly in association with the inferior vena cava. Intravascualar lipomas involving the subclavian vein are rare. We are reporting a case of an asymptomatic lipoma of the right subclavian vein, growing into the right brachiocephalic vein.

Streptococcus constellatus (S. constellatus) is a commensal microorganism belonging to the "Streptococcus milleri" group, but may cause infections in different locations in immunocompromised patients. The infection of S. constellatus has high mortality and morbidity due to its tendency to cause abscesses in infected patients, which require immediate surgical drainage for effective treatment. We report on a 72-year-old woman with end stage renal disease, who suffered from dyspnea and general weakness that had developed over 7 days. Chest CT showed loculated pleural effusion. S. constellatus was cultured from exudative pleural effusions and confirmed by an analysis of 16S rRNA sequence. The patient was treated with drainage of pleural effusion and piperacillin/tazobactam for 5 weeks.

A pseudochylothorax, a chyliform pleural effusion, is a rare disease of pleural effusion that contains cholesterol crystals or high lipid content that is not the result of a disrupted thoracic duct. Most of the cases were found in patients with long-standing pleural effusion due to chronic inflammatory disease, such as old tuberculous pleurisy or chronic rheumatoid pleurisy. We experienced a case of pseudochylothorax in a 74-year-old man, who was being treated for pulmonary tuberculosis and pleurisy 10 years ago. The diagnosis was confirmed on pathological study of the pleural effusion, which contained cholesterol crystals having a diagnostic rhomboid appearance.

STUDY DESIGN: Retrospective controlled study. OBJECTIVES: The aim of this study was to determine if unilateral TLIF is comparable to conventional PLIF with regard to radiologic and clinical outcomes, and to examine the viability of local bone for bone grafting in lumbar interbody fusion. SUMMARY OF LITERATURE REVIEW: TLIF, a modified form of PLIF, is a new spinal fusion technique that avoids the typical complications of PLIF. MATERIALS AND METHODS: We analyzed 32 cases of single-level TLIF or PLIF in patients with degenerative or isthmic spondylolisthesis, who were followed for more than 1 year. The patients in group 1 underwent TLIF, and the patients in group 2 underwent PLIF. The fusion rate, changes in disc height, and degree of anterolisthesis in the fused segment were analyzed radiologically. The clinical results were evaluated using the Oswestry Disability Index and visual analog scale. We also analyzed operative time, blood loss, and complications in both groups. RESULTS: Radiologically and clinically, there were no significant differences between the two groups in terms of fusion rate, changes in disc height, or degree of anterolisthesis in the fused segment. The mean operative time was 200 minutes in group 1 and 240 minutes in group 2. The mean blood loss was 854 ml in group 1 and 1102 ml in group 2(p>0.05). CONCLUSIONS: TLIF is a potentially useful alternative to conventional PLIF in patients with degenerative or isthmic spondylolisthesis. Additionally, local bone may be a viable source of bone grafts for single-level TLIF and PLIF.
