AbstractIntroduction: Our study investigated the importance of inflammation markers – ratio of platelets and lymphocytes (PLR), ratio of neutrophils and lymphocytes (NLR) and ratio of lymphocytes and monocytes (LMR) – as predictive markers in the occurrence of fistula or stenosis in patients diagnosed with gastric adenocarcinoma who underwent gastric resections.Materials and Methods: We conducted a retrospective study of 178 patients diagnosed with gastric adenocarcinoma. The included patients were divided into 3 groups: group 1 (77 patients, who underwent lower gastrectomy), group 2 (27 patients, who had upper polar gastrectomy otherwise known as proximal gastrectomy), group 3 (74 patients, who underwent total gastrectomy). Ratios of PLR, NLR, respectively LMR were calculated for all patients.Results: Out of 178 patients 52 (29.2%) developed postoperative stenosis and 16 patients (9.0%) had postoperative fistulae. The occurrence of anastomotic stenosis was associated with significantly higher preoperative platelet counts (p=0.043) and PLR values (p=0.023). ROC curve analysis indicated that the optimal PLR value for the prediction of gastric stenosis was 198.4 (AUC= 0.609, sensitivity: 59.6%, specificity: 61.9%). For the prediction of fistulization PRL also displayed the highest performance among the analyzed hematological parameters (AUC=0.561, sensitivity: 43.7%, specificity: 81.5%, cut-off value 116.6.Conclusion: Our study indicates the importance of PLR as e predictive factor in the occurrence of anastomotic complications (fistulae or stenosis) immediately following surgery in patients with gastric adenocarcinoma that undergo gastric resections. Further prospective studies on larger groups of patients are required, considering that PLR, NLR and LMR will be key markers in the clinical management of patients with gastric cancer.

Background: The primary health care physician is usually perplexed withregards to selection of initial therapy for patients presenting with fever. Some degrees ofhematological changes do exist in most patients with malaria. How often these changes doexist with malaria in our set up? And whether these changes are due to associated fever oractually resulting because of malaria. Objective: 1-To measure the frequency of abnormalhematological changes in malaria patients in our set up. 2-To compare the hematologicalparameters among subjects with laboratory proven malaria, fever but no malaria diagnosisand healthy controls. Design: Cross-sectional analysis. Place and duration of study: Thisstudy was carried out from May 2010 to Dec- 2010 at department of medicine PNS SHIFA, anddepartments of pathology PNS SHIFA and RAHAT, Karachi. Subjects and methods: Subjectswith history of fever and a clinical suspicion of malaria were recruited from primary physician’sOPD along with healthy age and sex-matched control. First, the frequencies of various abnormalfindings in hematological parameters were measured in subjects diagnosed to have malaria.Later, group-1: [Malaria (Laboratory positive) (n=74)], Group-2: [Fever (Laboratory negative)(n=104)] and group-3: [Age and sex matched controls (n=54)] were evaluated by one wayANOVA followed by post-hoc comparisons for significant differences among groups. Bloodcomplete picture were measured by automated hematology analyzer (Specifications: CELTAC- alpha, MEK-6410 K). Malaria parasite presence was confirmed by both slide examinationtechnique and immune-chromatographic (ICT) testing. Main outcome measures-Hemoglobin,white blood cells (WBC), platelets, PDW, % neutrophil. Results- 21.62 % cases from malariahad anemia, while the occurrence of leucopenia was 62.16%. This leukpenia was associatedwith relative neutrophil excess (63.51%). Thrombocytopenia was the most consistent findingamong our studied subjects (97.30%). The difference between the three groups were significantfor platelets [Group-1, Malaria (Laboratory positive) group= 86.42 (95%CI: 78.43-94.41)][Group 2, Fever (Laboratory negative) group = 192.47 (95%CI: 177.69-207.25)] and (Group-3,Age and sex matched control group=278.89 (95%CI: 254.16-303.62)] {p<0.001}, and WBC[Group-1, Malaria (Laboratory positive) group= 5.55 (95%CI: 5.08-6.01)] [Group 2, Fever(Laboratory negative) group = 6.68 (95%CI: 6.14-7.20)] and (Group-3, Age and sex matchedcontrol group=8.78 (95%CI: 8.01-9.55)] {p<0.001}. The results for % neutrophil and PDW werealso significant, but post-hoc comparison did not show significant differences between groupsthus differentiating a case of malaria from non-malaria fever or control. Conclusion: Malariadue to Plasmodium vivax is associated with thrombocytopenia and leucopenia in our set up.Moreover, the associated hematological parameters including % neutrophil and PDW may helpin augmenting a clinical diagnosis of malaria.

Breast cancer (BC) is the most commonly diagnosed cancer in women. The metabolism of iron is closely regulated by hepcidin which exerts its action by interacting with a ferroportin.  The aim of the present study was to assess the alterations in the levels of some serum biomarkers that have a role in iron homeostasis (hepcidin and ferroportin) in addition to hematological parameters (hemoglobin, leukocyte and platelets count) in different stages of BC. This study included 66 women with BC. The patients were categorized as follows : group 1 includes :22 patients with stage I disease ,group 2 includes: 22 patients with stage II disease ,and group 3 include: 22 patients with stage III disease .Group 4 includes :22 apparently healthy women as control. Data analysis revealed a significant elevation of serum hepcidin levels of patients groups 1, 2, and 3 (437.2±26.4, 501.4±31.8 and 558.5±21.3 pg/ml respectively) ,vs  (179.4±19.8 pg/ml) of control, with  steady elevations from stage I to III . Furthermore, serum ferroportin levels were significantly lowered in groups 1 and 3 compared to control  (0.589±0.107  and 0.733±0.1 vs 1.37±0.28 ng/ml respectively).While  blood hemoglobin level of group 3 were lower (11.96±0.18 vs  12.7±0.13g/dl ) compared with controls . Blood leukocyte count of patients (all groups) (7.39±0.28 ,8.93±0.48,9.86±0.52 (^103/µl) respectively) were markedly increased compared to controls (6.06±0.23), while mean platelet count for patients in group 2&3 were significantly increased compared to controls  (313.9±19.3,309.2±25.3 vs 233.3±9.1 respectively). In conclusion, hepcidin, ferroportin and hematological markers including hemoglobin, WBC count and platelets count are altered in women with BC compared to healthy control. The changes occur mostly in accordance with disease stages.

Abstract Translocations of 14q32/IgH have a low incidence in CLL. Partner chromosomes and the prognostic significance are poorly defined. Four hundred thirty cases of CLL seen at the Hospitals of Ferrara, Salamanca and Siena between 1992 and 2006 were studied. Inclusion criteria were: diagnosis of CD5/CD19+ CLL with k/λ restriction, cytogenetic/FISH data, immunophenotypic data, complete hematological and clinical data. Lymphomas in leukemic phase were excluded. FISH was performed for 17p13/TP53, 11q22.3/ATM, 6q21, chr 12 centromere, 13q14 and 14q32/IGH. Patients with no detectable aberration or isolated 13q− were included into a favourable cytogenetic group (group 1), those with +12, 6q− or 1–2 aberrations into an intermediate risk group (group 2) and those with 17p−, 11q−, ≥ 3 aberrations into an unfavourable group (group 3). Cases with 14q32/IGH translocation as primary chromosome change represented a specific category (group 4) and were studied with FISH probes for the detection of partners (BCL1, BCL2, BCL3, BCL6, c-MYC, BCL11A, PAX5, CCND3, CDK6). One hundred eighty-six cases were allocated into group 1; 158 into group 2; 64 into group 3, and 22 into group 4. Additional aberrations were found in a minority of cells in 8 patients in group 4. Being the aim of the study to assess whether the 14q32/IGH translocation represented an unfavourable parameter as compared with cases in the favourable or intermediate cytogenetic risk groups, cases within group 3 were excluded from the analysis and the data presented here will refer to 366 patients belonging to groups 1,2 and 4. Translocation partners of 14q32/IGH were identified in 9/22 cases: 2p13/BCL11A, (n 1); 6p21/CCND3 (n 1); 7q21/CDK6 (n 1); 18q21/BCL2 (n 6). Thirteen cases did not show involvement of the loci studied. Cases with 14q32/IGH translocations were characterized by typical morphology and classical immunophenotype (score 4–5 in 92% of the cases). Unmutated IGVH genes were found in 11/18 cases tested (61%); ZAP-70 was positive in 3/5 cases tested. Median age was 63.5 years (range 18–97), male:female ratio 240/126; 345 patients were in Rai stage 0-II, 21 were in stage 3–4; CD38 was positive in 137/366 cases. There was no difference between groups 1,2 and 4 for age, stage, male:female ratio, hematological parameters at diagnosis, IGVH mutations and ZAP70. CD38 was more positive in group 4 than in group 1 (p=0.028). There was no difference in survival and treatment free interval (TFI) when comparing cases in group 4 with and without additional aberrations. Cases in group 4 had a shorter TFI and a shorter survival when compared with group 1 (p=0.02) and group 2 (p=0.02). The difference maintained its statistical significance at multivariate analysis for TFI (p=0.02) along with stage (p<0.0001) and CD38 positivity (p<0.0001) and for survival (p=0.02) along with sex (p=0.006) and stage (p=0.0001). In conclusion, the 14q32/IGH translocation in CLL shows heterogeneity of partner chromosomes and it represents a cytogenetic marker predicting for an evolutive form of CLL.

During follicular development in the mammalian ovary, several functional changes occur in the granulosa cells in response to steroid hormones and gonadotropins (1,2). In particular, marked changes in the content of membrane-associated receptors for the gonadotropins have been observed (1).We report here scanning electron microscope observations of morphological changes that occur on the granulosa cell surface in response to the administration of estradiol, human follicle stimulating hormone (hFSH), and human chorionic gonadotropin (hCG).Immature female rats that were hypophysectcmized on day 24 of age were treated in the following manner. Group 1: control groups were injected once a day with 0.1 ml phosphate buffered saline (PBS) for 3 days; group 2: estradiol (1.5 mg/0.2 ml propylene glycol) once a day for 3 days; group 3: estradiol for 3 days followed by 2 days of hFSH (1 μg/0.1 ml) twice daily, group 4: same as in group 3; group 5: same as in group 3 with a final injection of hCG (5 IU/0.1 ml) on the fifth day.

Endothelial cell (EC) seeding is postulated as a mechanism of improving patency in small caliber vascular grafts. However the majority of seeded EC are lost within 24 hours of restoration of blood flow in previous canine studies . We postulate that the cells have insufficient time to fully develop their attachment to the graft surface prior to exposure to hemodynamic stress. We allowed EC to incubate on fibronectin-coated ePTFE grafts for four different time periods after seeding and measured EC retention after perfusion in a canine ex vivo shunt circuit.Autologous canine EC, were enzymatically harvested, grown to confluence, and labeled with 30 μCi 111 Indium-oxine/80 cm 2 flask. Four groups of 5 cm x 4 mm ID ePTFE vascular prostheses were coated with 1.5 μg/cm.2 human fibronectin, and seeded with 1.5 x 105 EC/ cm.2. After seeding grafts in Group 1 were incubated in complete growth medium for 90 minutes, Group 2 were incubated for 24 hours, Group 3 for 72 hours and Group 4 for 6 days. Grafts were then placed in the canine ex vivo circuit, constructed between femoral artery and vein, and subjected to blood flow of 75 ml per minute for 6 hours. Continuous counting of γ-activity was made possible by placing the seeded graft inside the γ-counter detection crystal for the duration of perfusion. EC retention data after 30 minutes, 2 hours and 6 hours of flow are shown in the table.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.

This study was conducted to find out hepatoprotective activity of hesperidin (HES) 100mg/kg body weight (b.w.) against ciprofloxacin (CPX) 100 mg/kg induced hepatotoxicity in local breed rabbits .CPX is a broad spectrum antibiotic used for treatment of many bacterial infections. Twenty four male rabbits were divided into four groups ,group1: control, (1 ml/kg Saline orally) group 2: CPX (100 mg/kg orally) for (14) consecutive days , group 3: HES (100 mg//kg) orally for (14) consecutive days group 4: CPX (100 mg/kg orally) plus HES (100 mg//kg orally ) for (14) consecutive days. All the rabbits were killed on the (15) day of the experiment, and then the blood, and livers samples were taken. CPX induced hepatotoxicity was proved by a significant (p less than 0.01) reduction in the body weight ,and a significant (p less than 0.01) increased serum aspartate transaminase (AST), alanine transaminase (ALT) , Malonaldehyde enzyme (MAD) and histopathological changes. Protective hepatic toxicity effect and oxidative damage caused by CPX significantly (p less than 0.01) increasing in body weight and significantly (p less than 0.01) decreasing AST , ALT, MAD and improving tissue morphology in HES (100 mg//kg) . These results assure that HES (100 mg//kg) antioxidant effects can protect CPX-induced hepatotoxicity in rabbits.

The purpose of the study was to conduct a comparative assessment of the course of the postoperative period after phlebectomy and thermal ablation in patients with varicose veins of the lower extremities in the system of the great saphenous vein (GSV) with class C2 of chronic venous insufficiency (CVI) — CEAP class C2. Materials and methods: 455 patients (455 limbs) with CEAP class C2. Group 1 (n = 154) received stripping + minimally invasive phlebectomy; Group 2 — endovenous laser ablation (EVLA) of GSV trunk + sclerotherapy of varicose veins; 3 group (n = 150) — radiofrequency ablation (RFA) of the GSV + sclerotherapy. All patients were united by a single tactical solution — the elimination of pathological vertical reflux in GSV. In each group, patients were with similar hemodynamic profile were selected (Group 1 = 63; Group 2 = 61; Group 3 = 61). The course of the postoperative period (from 2 days to 2 months) was compared for pain (visual analog scale — VAS), clinical symptoms of chronic venous insufficiency, degree of satisfaction (Darvall questionnaire), and duration of disability. Statistical processing was carried out using Excel programs for Windows XP, MedCalc® (version 11.4.2.0., Mariakerke, Belgium). Results: Postoperative pain is more pronounced (during day 1 for Group 1–4.0, Group 2–3.0, Group 3–2.0) and more prolonged (up to 4 days) after open surgeries (p < 0.05). The dynamics of the clinical symptoms of CVI (including varicose syndrome and use of compression therapy) could not be fully evaluated in connection with the ongoing sclerotherapy procedures for patients of Groups 2 and 3. Satisfaction of patients with aesthetic aspects was higher than expected in all groups. Reliable statistical differences proved decrease in days of disability (Group 1–14; Group 2–4; Group 3–3) and earlier return to physical activities and work in patients after thermal ablation in comparison with phlebectomy. Conclusion: The study shows that all three methods for eliminating vertical reflux in the GSV can be proposed for a large category of patients with CEAP of class C3 and C2. Medical and social rehabilitation of patients using endovascular thermal ablation technologies proceeds faster, which is beneficial both for the patients and for society.
