The presen study was carried out to evaluate the use of some probiotics on the growth rate of tilapia fishes and to determine its effect on some hematological and histopathological parameters. Two different commercial probiotics which includes biogen and moreyeast were evaluated for 8weeks. In the experiment, fifty Oreochromis niloticus fishes were classified to 3 groups,Group (1): consisted of 20 fishes which fed diet supplemented by biogen at a dose of 2 kg/ton diet. Group (2): consisted of 20 fishes which fed diet supplemented by moreyeast at a dose of 5 kg/ton diet and Group (3): was control group which consisted of 10 fishes fed diet without probiotics. At the end of the experimental period both biogen and moreyeast administrated groups revealed a significant increase in the body weight gain (W.G.). The results showed significant increase in the values of RBCs, PCV and Hb throughout the experimental period except group 1 (received biogen) at the 6th week of experiment comparing to control group. Fish group received moreyeast (Group 2) had the pronounced effect than group 1. Assessment of leukogram revealed significant leukocytosis allover the experimental period in different groups except during the 2nd week in group 2 (received moreyeast) and at the 6th week in both probiotic administrated groups comparing to control group. Fish group received biogen had pronounced effect comparing to moreyeast administrated group. differential leukocytic picture was recorded. Histopathological examination revealed The biogen and moreyeast administerd groups showed marked activation of the melano-macrophage centers which is a component of reticuloendothelial system and hence part of the defensive system of fish indicating immunoenhancment. the study concluded that: The examined probiotic were safe for the Oreochromis niloticus fish.

Abstract

OBJECTIVE: Laparoscopic radical prostatectomy (LRP) has been refined by experienced surgeons into a competitive treatment alternative for localized prostate cancer. Less is known, however, about the outcomes of "learning curve" cases from newly trained surgeons. We prospectively studied 100 cases of LRP performed by 2 senior and 2 junior surgeons and addressed the rates of positive margins-an important early endpoint of oncologic efficacy.

METHODS: 100 consecutive cases of LRP were performed by two senior (n=62) and two junior surgeons (n=38) by a 5-port transperitoneal route. Whole-mount step-section prostate specimens were examined by Stanford protocol.

RESULTS: Positive margins occured in 25% of cases: 18% for pT2a (2/11), 18% for pT2b (11/61), 45% for pT3a (10/22), and 50% for pT3b (2/4) (p=0.002 pT2 vs. pT3). By surgeon experience, the rates were 19% (12/62) for senior and 34% (13/38) for junior (p=0.04). However, in a multiple logistic regression analysis, only pathologic stage (p=0.083) and Gleason sum (p=0.0133) reached statistical significance, while surgeon experience did not (p=0.0992).

CONCLUSION: Positive margin rates after laparoscopic radical prostatectomy are significantly influenced by pathologic stage and Gleason score, and are within the range reported from open series. The higher positive margin rate from junior surgeons, although not statistically significant, suggests the need for further study and continued mentoring during surgery and/or video review of cases to improve oncologic results.

OBJECTIVES: Although laparoscopic radical prostatectomy (LRP) is accomplished within 2 to 3 hours by experienced surgeons, less is known about the operating times (OTs) for recently trained surgeons or the influence of additional factors. As of November 2001 at our institution, two senior surgeons had each performed more than 100 cases of LRP and two junior surgeons had each performed fewer than 30. We prospectively studied the next 100 consecutive LRPs to assess the factors influencing the OT.

METHODS: Transperitoneal LRPs were performed by two senior (n = 62) and two junior surgeons (n = 38) with random case assignment. We assessed body mass index, prostate size, prior abdominal surgery, androgen deprivation, surgeon experience, procedures in addition to LRP, lymph node dissection, nerve sparing, and sural nerve grafting as potential predictors of the OT.

RESULTS: Prostate weight, androgen deprivation, and prior abdominal surgery did not significantly affect the OT, but grade 1 obesity increased the OT by an average of 38 minutes. The mean OT by surgeon experience was 214 minutes for seniors and 347 minutes for juniors (P <0.001). By procedure type, the OT ranged from 180 minutes for LRP only by seniors to 459 minutes for LRP plus lymph node dissection plus sural nerve grafting by juniors. Lymph node dissection and sural nerve grafting significantly increased the OT by 46 and 101 minutes, respectively, and nerve sparing did not. For each combination of procedures, seniors averaged significantly shorter times than did juniors. A multiple regression model with stepwise selection showed that prostate weight, sural nerve grafting, pelvic lymph node dissection, use of a surgical robot, and surgeon experience significantly affected the OT.

CONCLUSIONS: The results of this prospective study of 100 cases of LRP showed that the OT for senior surgeons averaged 2 to 3 hours, but less experienced surgeons, and additional procedures, add significantly to the OT.

{Viral hepatitis is a common and important problem in immunocompromised cancer patients. The present study was conducted to investigate changes in some cellular and humoral immunological parameters as a consequence of HCV infection in non Hodgkin's lymphoma patients (NHL). The study included 40 NHL patients: 20 anti-HCV antibody positive (Gr. I ), and 20 anti-HCV antibody negative (Gr.II ). In addition, forty non-cancer controls (NCCs) were included: 20 of them were anti-HCV antibody positive (Gr. III) and 20 anti-HCV antibody negative (Gr. IV). The studied immunological parameters included serum levels of interleukin-1 (IL-1), interleukin-2 (IL-2), interleukin-6 (IL-6), and soluble tumor necrosis factor receptors (s-TNFr) measured by ELISA, as well as assessment of T and B lymphocyte subsets by PAP immunostaining method. Mean IL-1 level (pg/ml) was significantly higher in Gr. 1 (14 +/- 6) and Gr. III (20 +/- 12) as compared to those in Gr. II (7 +/- 5) and Gr. IV (9 +/- 6). Mean IL-2 level (pg/ml) was also significantly higher in Gr. I (132 +/- 101) and Gr. III (135 +/- 59) compared to those in Gr. II (36 +/- 29) and Gr. IV (31 +/- 48). On the other hand, level of IL-6 showed no significant difference between groups. The mean level of sTNF-r, (ng/ml) was only significantly higher in Gr. I (2.9 +/- 1.7) when compared to that in Gr. IV (1.9 +/- 2.2). In group IV, the average percentage of CD3 (70 +/- 4%) and CD4 (44 +/- 5%) were significantly higher than in those of Gr. I (CD3 = 51 +/- 11%

el-Mawla, N. G., M. N. el-Bolkainy, and H. M. Khaled, "Bladder cancer in Africa: update.", Seminars in oncology, vol. 28, issue 2, pp. 174-8, 2001 Apr. Abstract

Carcinoma of the bladder is the most prevalent cancer in Egypt and in most African countries. At the National Cancer Institute (NCI), Cairo, it constitutes 30.3% of all cancers. The median age at diagnosis is 46 years, with a male preponderance of 5:1. Whether in Egypt or other African countries such as Sudan, Kenya, Uganda, Gold Coast, and Senegal, it is mostly of the squamous cell type, and arises in a background of schistosomiasis or bilharziasis. Tumors are usually advanced at the time of presentation. Bladder carcinogenesis is probably related to bacterial and human papilloma virus (HPV) infections, usually associated with bilharzial infestation. Management is mainly surgery, with 5-year survival rates after radical cystectomy increasing from 35% in the 1970s to 48% in the 1990s. The addition of adjuvant and neoadjuvant radiotherapy and chemotherapy to surgery since 1976 significantly improved both disease-free and overall survival rates. Molecular genetic studies concerning potential prognostic markers, tumorigenesis, and tumor progression in bilharzial bladder cancer are limited. However, a comprehensive detailed analysis of these factors is underway. Bilharzial bladder cancer is a preventable malignant disease. Primary prevention could be possible if the parasite is eliminated nationwide. Chemoprevention using retinoids or cyclooxygenase 2 (COX-2) inhibitors is a possible alternative.

Objective.The objective of this study is to evaluatethe efficacy of image-guided
systems in nasal and skull base surgeries.Study design. This is a prospective case
control study. Material and methods. A total number of 24 patients were included in this
study. The relevant pre-operative, operative and post-operative records were collected
and analyzed. Results:The mean total operative time was greater for the imageguidance
surgery group (130 minutes; range 95-160 minutes) than for the control
group (119 minutes; range 85-150 minutes). However, the mean actual operative time
was less for the image-guidance surgery group (93 minutes; range 65-120 minutes)
than the control group (99 minutes; range 70-130 minutes).The image-guidance
surgery group had no major complications. However the control group had 3 major
complications (25%).The average estimated blood loss (EBL) was higher for the
image-guidance surgery group (395 mL; range 130-1100 mL) than the control group
(380 mL; range 100-950 mL).Conclusion: Image guided system may reduce the
complications associated with endoscopic sinus surgery and allow for a more thorough
