Unusual presentation of tuberculosis as a splenic mass.
Tuberculosis is an important health problem in developing countries, with varying clinical presentations depending on the organs/systems involved. Tuberculosis is mostly seen in immuno-compromised individuals, such as those with acquired immune deficiency syndrome or malignancies. Here we report a case of a spleen tuberculoma in a 29-year-old male patient with no known immune deficiency. He first presented with abdominal pain, and subsequent ultrasonographic examination revealed a splenic lesion of 10 cm in diameter. A computerized tomography scan of the abdomen confirmed the presence of a solitary, hypodense, septated cystic lesion. Lack of evidence supporting the presence of a splenic infection or a primary/metastatic malignancy prompted explorative surgery where a septated abscess formation was discovered and splenectomy was performed. Histopathological examination revealed granulomatous inflammatory changes with Langerhans-type giant cells, which are consistent with tuberculosis. For a period of two months, antituberculosis therapy with four drugs, isoniazid, rifampicin, pyrazinamide, and ethambutol, was carried out. Pyrazinamide and ethambutol were quitted at the end of two months. Therapy with isoniazid and rifampicin was planned for an additional 10 months. We would like to call attention to yet another atypical presentation of extrapulmonary tuberculosis.

Focal segmental glomerulosclerosis associating Kimura disease.
Kimura disease presents as a benign subcutaneous mass. Although it principally affects the skin and soft tissues, there is a high prevalence of related renal disease. We report a case of Kimura disease from western Asia, presenting itself as nephrotic syndrome, and this case was seen at a nontransplant kidney presenting with focal segmental glomerulonephritis.

The effect of high-flux hemodialysis on renal anemia.
BACKGROUND: Anemia is an important predictor of mortality and morbidity in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). Erythropoietin (EPO) is an expensive drug, which increases the cost of therapy. In addition, anemia persists in 20-30% of cases despite EPO treatment. In this study, which depended on the idea that the clearance of moderate and high molecular weight erythropoiesis inhibitors leads to an improvement in terms of anemia, we aimed to investigate the effect of high-flux dialysis on anemia and EPO requirement in patients undergoing HD. METHODS: The study included 48 patients with ESRD on chronic HD treatment who could not reach the target hemoglobin (Hb) level, despite treatment with at least 200 IU/kg/week subcutaneous EPO. Patients were randomized into two groups and HD was performed with polysulphone low-flux dialyzer (Fresenius F6 HPS) or polysulphone high-flux dialyzer (Fresenius F60) for 6 months. RESULTS: Although the EPO doses were significantly lower (p<0.001) in the high-flux dialysis group, Hb levels showed a significant increase (p<0.001). In the low-flux dialysis group, Hb levels showed no significant increase, despite the steady increase in EPO doses. In the high-flux group, the reduction of beta2-microglobulin (b2-MG) and phosphorus levels during dialysis was significantly higher when compared to the low-flux group (p<0.001). During the follow-up period, while b2-MG levels decreased significantly in the high-flux group (p<0.05), there was an increase in the low-flux group (p<0.05). Kt/V(urea) values showed no significant difference throughout the study. CONCLUSIONS: Our results suggest that high-flux dialysis use is effective and this can be an alternative method in terms of controlling renal anemia and reducing the cost of therapy. These beneficial effects of high-flux dialysis are probably mediated by the improved clearance of moderate and high molecular weight toxins.
