Long-term response to sunitinib: everolimus treatment in metastatic clear cell renal cell carcinoma.

AIM: The study aim was to evaluate progression-free survival (PFS) and overall survival (OS) in patients with metastatic clear cell renal cell carcinoma on sunitinib (SU) and SU-everolimus treatment. PATIENTS & METHODS: After 7 years of enrollment and 9 years of follow-up, 193 consecutively presenting patients (151 men and 42 women) were treated. RESULTS: A total of 157 patients (81.3%) died and 36 patients (18.7%) survived. Median PFS in 193 SU-treated patients was 14.7 months and OS was 28.8 months. Median PFS was 13.98 months and median OS was 26.67 months in 175 patients treated with SU only or on SU-everolimus. CONCLUSION: The development of SU-induced hypothyroidism, hypertension, neutropenia and edema was a significant predictive and prognostic factor.

Intracameral concentrations of the fibrinolytic system components in patients with age-related macular degeneration.

PURPOSE: To detect the intracameral concentrations and activities of plasminogen and other components of the fibrinolytic system, and to investigate whether those concentrations and activities are higher in patients with age-related macular degeneration (AMD) in comparison to healthy controls. METHODS: Prospective case series of 93 patients scheduled for standard phacoemulsification. RESULTS: Mean plasminogen activity in patients with non-exsudative AMD (n = 24) revealed to be 0.06%N, in patients with exudative AMD (n = 7) 0.03%N and in healthy controls (n = 43) 0.02%N (p = 0.38, ANOVA). Plasminogen activator inhibitor I (PAI-1) was detected in neither group. Alpha2-antiplasmin activity was 1.61 U/ml in the non-exudative AMD group (n = 27), 0 U/ml in the exudative AMD group (n = 7) and 0.54 U/ml in the control group (n = 48) (p = 0.1, ANOVA). Concentrations of plasmin-a2-antiplasmin complex (PAP) were detected at levels of 17.91 ng/ml in the non-exudative AMD group (n = 11), of 16.6 ng/ml in the exudative AMD group (n = 5), and of 17.43 ng/ml in the control group (n = 14) (p = 0.92, ANOVA). CONCLUSIONS: Plasminogen is present with a very low activity in aqueous humor. There are no significant differences in aqueous humor concentrations or activities of plasminogen and other components of the fibrinolytic system between patients with non-exudative AMD, exudative AMD, and healthy controls. Further studies should investigate vitreous samples instead of aqueous humor samples. A careful and accurate workup of obtained intraocular fluids is needed to detect the low concentrations and activities of the parameters analyzed.

Hashimoto's thyroiditis and carbohydrate metabolism disorders in patients hospitalised in the Department of Endocrinology and Diabetology of Ludwik Rydygier Collegium Medicum in Bydgoszcz between 2001 and 2010.

INTRODUCTION: Chronic lymphocytic thyroiditis, also known as Hashimoto's thyroiditis, is the most frequent type of thyroiditis. An average of 2% of the population have the disease. It occurs in all age groups, also in children. The main cause of the disease are autoimmune disorders, which results in incresed risk of suffering from type 1 diabetes. Fourthermore, during the course of Hashimoto's thyroiditis, hypothyroidism may cause carbohydrate metabolism disorders. Aim of our study was estimate disturbances of glycaemia in patients with recognized Hashimoto's thyroiditis, hospitalized in Endokrinology and Diabetology Depatment of Collegium Medicum University of Nicolaus Copernicus in Bydgoszcz in years 2001-2010. MATERIAL AND METHODS: We examined 54 patients with the diagnosis of Hashimoto thyroiditis based on clinical picture and examination(autoantibodies anti-TPO and anti-Tg). RESULTS: In the tested group with Hashimoto's thyroiditis, diabetes has been confirmed in 27.8% of the patients; impaired fasting glycaemia (IFG) or impaired glucose tolerance (IGT) occurred in 16.6%, whereas a normoglycaemia has been confirmed in 55.6% of the pacients. An average age of the patients with Hashimoto's thyroiditis and diabetes at the same time, was 53 years. The patients in which we confirmed the impaired fasting glycaemia or impaired glucose tolerance were on average 49.9 years old. An average age of the patients without any carbohydrate methabolism disorders was on average 43.1 years. CONCLUSIONS: Carbohydrate metabolism disorders in the form of type 1 diabetes connected with an autoimmune process, as well as type 2 diabetes connected with the increase of the insulin resistance, occured in average of half of the patients with Hashimoto's thyroiditis.

Sampling aqueous humor: anterior segment anatomy, anesthetic and surgical technique, and rates of yield.

PURPOSE: To evaluate anterior segment anatomy and anesthetic and surgical techniques with respect to the amount of aqueous humor (AH) that can be sampled out of the anterior chamber (AC) at the beginning of standard cataract removal procedures (phacoemulsification). METHODS: In a prospective survey, volumes of sampled AH from 123 eyes (110 patients) were analyzed in regard to AC anatomy (anterior chamber depth, ACD) and different anesthetic techniques (local and general anesthesia). RESULTS: 107 eyes (87%) were included into our analysis, and 16 eyes (13%) had to be excluded due to failure of AH collection. We found a significant positive association between ACD and obtained AH volume (p=0.007). In general anesthesia, a strong trend to acquire more AH in comparison to local anesthesia was apparent, but statistical significance failed (p=0.167). Different anesthetic techniques seem to have no significant influence on ACD (p=0.169). No training curve for the individual surgeon was obtained. No complications were observed. CONCLUSION: When AH sampling is performed in eyes with a deep AC and when the procedure is performed under general anesthesia, more AH can be aspirated.
