Brown Tumors: A Case Report and Review of the Literature

Brown tumors are focal bone lesions, encountered in patients with uncontrolled hyperparathyroidism. They can be located in any part of the skeleton. Clinically significant lesions in the craniofacial bones are rare. Craniofacial involvement may cause facial disfiguration and compromise social ease of the patient and normal functions, such as chewing, talking, and breathing. In this case report, we present a patient with a brown tumor of the craniofacial bones provoked by secondary hyperparathyroidism and review the last 10 years of craniofacial brown tumors associated with secondary hyperparathyroidism in the English literature.

Robotic Kidney Transplantation: Comparison of the First 40 Cases of Open vs Robotic Transplantations by a Single Surgeon

To compare the outcomes of the first 40 patients to undergo robot‐assisted kidney transplantation (RAKT) with those of the first 40 patients who underwent open KT (OKT) by a single surgeon at the Dr Sadi Konuk Training Hospital.

Rapidly Progressive Glomerulonephritis: A Single-Center Experience

OBJECTIVE: Rapidly progressive glomerulonephritis is associated with rapid deterioration of kidney function. We aimed to evaluate patients followed-up with the diagnosis of rapidly progressive glomerulonephritis. MATERIAL and METHODS: This retrospective study included 28 patients who were compared for remission status and baseline serum creatinine levels. RESULTS: We evaluated 20 male and 8 female patients with a mean age of 46.68 ±15.94 years. Patients with higher baseline serum creatinine had significantly lower hemoglobin (p=0.01), platelet counts (p=0.01) and calculated eGFR at last hospital visit (p=0.03) compared to patients with lower baseline serum creatinine. At discharge, the number of dialysis-dependent patients was significantly higher in the patients with higher baseline serum creatinine than the patients with lower baseline serum creatinine (p=0.01). Patients who had achieved remission had significantly lower percentage of cellular crescents (p= 0.009) and sclerotic glomeruli (p= 0.04) than patients who did not achieve remission. Dead patients were more likely to have a lymphocyte count of < 1000 cells/mm3 (p=0.009). CONCLUSION: Patients with high baseline serum creatinine levels were more likely to have lower hemoglobin levels and platelet counts. High baseline serum creatinine level and high percentage of cellular crescents and sclerotic glomeruli were related to worse renal prognosis. Patients with lower lymphocyte counts had higher mortality rates.

The Factors Affecting Survival in Geriatric Hemodialysis Patients

Introduction The number of geriatric patients is increasing in hemodialysis population over the years and mortality is higher in this group of patients. This study evaluated the factors affecting geriatric hemodialysis patient survival. Materials and Methods This retrospective cohort study enrolled patients discharged from our nephrology clinic from 2009 to 2014. Data collected included demographics, Eastern Cooperative Oncology Group-Performance Status, vascular access type, and metabolic parameters. Comorbidity was quantified using the modified Liu comorbidity index. The outcome measure was mortality. Results The study enrolled 99 elderly dialysis patients (42.4% women (n = 42); mean age 75 ± 7 years). The mean follow-up duration was 19.7 ± 11 months. The mortality rate over the four years was 47.5% (n = 46). The modified Liu comorbidity index score, patient age, and Eastern Cooperative Oncology Group-Performance Status were significantly related to mortality in univariate and multivariate analyses. Conclusion The present study revealed that comorbidities and low performance status at the onset of dialysis had shortened the survival time in the geriatric hemodialysis patient group.
