RESUMO

The present study deals with the description of a new piscine trypanosome species found infecting the fresh water fish Schizothorax plagiostomus Heckel from river Jhelum, Srinagar, J&K, India and evaluating the haematological parameters of the infected fish. Haematological examination of S. plagiostomus revealed 61.1 % infection with an intensity of 1-9 trypanosomes/100 RBC's. Small (26.9 ± 1.39 µm) and large (47.17 ± 3.50 µm) forms of the trypanosome were observed in light microscopy investigations, revealing the dimorphic nature of the species. The trypanosome species was found to be distinct from the other related dimorphic species in morphometric dimensions including cell length, cell breadth, kinetoplast index, flagellar index, and cytological peculiarities, respectively. The detailed descriptions of the two morphological forms found in the blood of S. plagiostomus are provided. Based on the geographical location, morphometrics, cytological peculiarities, host status and comparative study, the new species is named Trypanosoma kashmirensis n. sp. The parasitic infestation caused a significant decrease (p < 0.05) in red blood cell counts, haematocrit and haemoglobin concentrations while, the leucocyte (WBC) count, mean cellular volume and mean cellular haemoglobin showed a significant increase (p < 0.05) in the infected fish as compared to the non-infected. The above alterations of the haematological parameters could be used as an important tool for the indication of Trypanosoma infection in the fish.

RESUMO

BACKGROUND: The aim of this epidemiological study was to establish the laterality of breast cancer (BC) and its association with size, receptor status of the primary tumor and bone metastasis (BM) in a local population. MATERIALS AND METHODS: This retrospective study included cases of BC from Jan-2009 to Dec-2011 who were referred for metastatic work up or follow up survey with Technetium-99m MDP bone scan (BS) to the Nuclear Medicine Department of Karachi Institute of Radiotherapy and Nuclear Medicine (KIRAN). A total of 384 patients out of 521 were included and all reviewed for age, primary tumor size (PTS), laterality, receptor status like estrogen receptor (ER) progesterone receptor (PR) and Her-2-Neu receptor, presence or absence of BM with sites of involvement and time interval between diagnosis of BC and appearance of BM. RESULTS: The left to right sided BC proportion was significantly higher than unity (59%:41%; p<0.001). The right sided BC was observed in younger age group (46:52 years; p<0.0001) and with a smaller PTS than the left sided (3.43:4.15 cm; p<0.0001). The patients with BM had relatively higher negative receptor status with a significant predominance of right sided BC. The overall incidence of BM on BS was 28% and relatively higher in right than left breast (33%:24% p=0.068). The average number of BM sites was also significantly greater for the right side (6:4, P<0.0001). The % cumulative risk of BM in right breast was noted at significantly smaller PTS than left side with log rank value of 5.579; p<0.05. The Kaplan Meier survival plot for event free survival of BM in left sided BC was significantly higher than for the right side (log rank value=4.155, p<0.05), with an earlier appearance of BM in right BC. CONCLUSIONS: 1) A left sided predominance of BC was seen in local population; 2) right sided BC had a more aggressive behavior with extensive and earlier appearance of BM at relatively younger age, smaller PTS and receptor (s) negativity.
