Comparing oncologic outcomes in patients undergoing surgery for oncocytic neoplasms, conventional oncocytoma, and chromophobe renal cell carcinoma

Introduction Oncocytic neoplasms are renal tumors similar to oncocytoma, but their morphologic variations preclude definitive diagnosis. This somewhat confusing diagnosis can create treatment and surveillance challenges for the treating urologist. We hypothesize that these subtle morphologic variations do not drastically affect the malignant potential of these tumors, and we sought to demonstrate this by comparing clinical outcomes of oncocytic neoplasms to those of classic oncocytoma and chromophobe. Methods We gathered demographic and outcomes data for patients with variant oncocytic tumors. Oncologic surveillance was conducted per institutional protocol in accordance with NCCN guidelines. Descriptive statistics were used to compare incidence of metastasis and death against those for patients with oncocytoma and chromophobe. Three hundred and fifty-one patients were analyzed: 164 patients with oncocytoma, 28 with oncocytic neoplasms, and 159 with chromophobe tumors. Results Median follow-up time for the entire cohort was 32.4 months, (interquartile range 9.2–70.0). Seventeen total patients (17/351, 4.9%) died during the course of the study. In patients with oncocytoma or oncocytic neoplasm, none were known to metastasize or die of their disease. Only chromophobe tumors >6 cm in size in our series demonstrated metastatic progression and approximately half of these metastasized tumors demonstrated sarcomatoid changes. Conclusion Variant oncocytic neoplasms appear to have a natural course similar to classic oncocytoma. These tumors appear to have no metastatic potential, and oncologic surveillance may not be indicated after surgery

Detection of coffee ringspot virus (CoRSV) in the mite vector by RT-qPCR.

The mite Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) is responsible for the transmission of coffee ringspot. There is a great interest in the study of Brevipalpus transmitted viruses (BrTVs), and the interaction between them, their vectors and hosts. Electron microscopy analyses suggest that CoRSV replicates in the mite tissue, what would characterize a persistent propagative virus-vector relationship. This study aimed to establish a transcriptase quantitative polymerase chain reaction (RT-qPCR) method to evaluate and compare the replication capacity of the virus in the vector. Total RNA was extracted from a sample of 100 mites reared in symptomatic plants for CoRSV using two different methods: CTAB and Nucleo Spin RNA XS Kit (Macherey-Nagel) and quantified in a NanoDrop 8000 (Thermo Scientific).Abstract 10

Chickens (Gallus domesticus) are natural intermediate hosts of Neospora caninum.

Neospora caninum naturally infects many mammal species, but has not previously been demonstrated in birds. We examined sera for N. caninum antibodies from 200 outdoor chickens and from 200 chickens confined indoors in the state of Bahia, Brazil. Seroprevalence was greater in outdoor chickens (23.5% versus 1.5%, P < 0.001). PCR testing for N. caninum was positive in six of 10 seropositive chickens. Amplicons from two of these were sequenced and had 97?98% nucleotide identity with N. caninum. This finding extends the list of intermediate hosts of N. caninum to include birds and may have important epidemiological consequences.Short communication
