Kaposi's sarcoma concurrent with granulomatosis polyangiitis.

Kaposi's sarcoma (KS), a malignant vascular tumor, can develop in patients who receive corticosteroids or immunosuppressive therapy. We report a patient with KS and granulomatosis polyangiitis (GPA). To the best of our knowledge, this is the first report regarding the co-occurrence of these two diseases. The physician must be aware of the risk of cancer in patients with rheumatism.

Effects of acute kidney injury on clinical outcomes in patients with upper gastrointestinal bleeding.

AIM: Upper gastrointestinal bleeding (UGIB) is a very frequently encountered condition that has a high morbidity and which increases treatment costs. Duration of hospital stay and mortality increases in patients with UGIB complicated by acute kidney injury (AKI). The aim of this study was to reveal risk factors in patients with UGIB developing AKI and to compare clinical outcomes and hospital costs between patients with UGIB developing AKI and those with UGIB not developing AKI. MATERIAL AND METHODS: This retrospective study included 245 patients admitted to the emergency unit and the intensive care unit for internal diseases at Ankara Numune Education and Research Hospital, Turkey. RESULTS: The difference in mortality rates between the patients with AKI and those without AKI was significant (p < 0.001). The mean duration of intensive care unit stay was 0.2 ± 1.1 days in the patients without AKI (n = 143) and 2.5 ± 5.6 days in the patients with AKI. It was significantly higher in the patients with AKI (p < 0.001). Hospital stay was significantly longer in the patients with AKI than those without AKI, and as severity of AKI increased, hospital stay became considerably longer (p < 0.001). Hospital costs were significantly higher in the patients with AKI than those without AKI, and as severity of AKI increased, hospital costs considerably rose (p < 0.001). CONCLUSION: AKI is a condition that lengthens hospital stay, increases hospital costs and creates a burden on health care systems. Detect kidney injury earlier and administering an appropriate treatment can improve clinical outcomes in patients with UGIB developing AKI.

Urine iodine excretion in patients with euthyroid noduler disease.

BACKGROUND AND OBJECTIVES: Different nutritional and environmental factors are responsible for the pathogenesis of goiter, but iodine deficiency is the most important factor. However, little is known about the natural course of benign thyroid nodules in euthyroid patients over time. Few studies have used ultrasonographic evaluation to address this issue, especially in iodine-deficient areas. In this study, we present the long-term follow-up of benign thyroid nodules in a iodine-deficient area. DESIGN AND SETTING: Cross-sectional study at a tertiary referral center. PATIENTS AND METHODS: This study included 62 randomly selected patients with benign euthyroid nodule. Thyroid volume and nodules were measured with sonography. Iodine intake was estimated by patient diet history and by measuring iodine excretion in spot urine samples. Patients were followed one year. RESULTS: Patients were divided into three groups according to level of urine iodine excretion: Group 1: <50 µg/L (severe iodine deficiency group), Group 2: 50-100 µg/L (mild iodine deficiency group), Group 3: >100 g/L (iodine sufficient group). The presence of additional disease (hypertension, diabetes mellitus, coronary heart disease, chronic renal failure and a history of any medication for chronic disorder) and smoking rates were significantly higher in first group compared to the second and third group. Among groups, no significant difference was observed in either right or left thyroid lobe volume after one year. A clinically significant increase in nodule volume was observed in the first group, while there was a significant decrease in the second and third group. CONCLUSION: In this study, iodine deficiency was associated with an increase in thyroid nodule volumes. Smoking rates were higher in iodine deficient groups. It is thought that smoking impairs iodine intake or absorption consistent with a previous report.
