In this work Hank's balanced salt solution (HBSS) has been used, as resuspension medium, instead of leukocyte poor plasma (LPP) to label autologous white blood cells in 28 patients with suspicion af active inflammatory bowel disease.Labelled cells were reinjected and anterior and caudo-craneal views were obtained at 30 min, 2 h and 6 h p.i. Regions of interest were outlined on liver, spleen, lung, bone marrow (spine), background and lesions and the organ/background activity ratios were calculated in all scans. Patients were classified into 2 groups: Group 1: LPP, 30 patients and Groups 2: HBSS, 28 patients. Labelling efficiency was higher in HBBS group (89.0 ± 3.2 %) than in the LPP group (6.5 ± 6.3%). Organ/background activity ratios were similar in both groups. Concerning diagnostic accuracy was similar at 30 min and 2 h but the false positive rate increased at 6 h p.i. in the HBSS group. HBSS seems to be a valid alternative as resuspension medium in the labeling of autologous leukocytes but leukocyte poor plasma seem to induce less leukocyte damage. Based on these results, in our center HBSS is the currently used medium to label leukocytes.

The purpose of this report is to evaluate the association between lower genital tract inflammation and objectively diagnosed endometritis. We analyzed the first 157 patients enrolled in the PEACH study, a multicenter randomized clinical trial designed to compare the effectiveness of outpatient and inpatient therapy for PID. Women less than 38 years of age, who presented with a history of pelvic discomfort for 30 days or less and who were found to have pelvic organ tenderness (uterine or adnexal tenderness) on bimanual examination, were initially invited to participate. After recruitment of the first 58 patients (group 1) we added the presence of leukorrhea, mucopurulent cervicitis, or untreated positive test forN. gonorrhoeaeorC. trachomatisto the inclusion criteria (group 2, N = 99). We compared rates of endometritis in the two groups and calculated the sensitivity, specificity, and predicted values of the presence of white blood cells in the vaginal wet preparation. The rate of upper genital tract infection in group 1 was 46.5% (27/58) compared to 49.5% (49/99) in group 2. Microbiologic evidence of eitherN. gonorrhoeaeorC. trachomatisincreased from 22.4% in group 1 to 38.3% in group 2. The presence of Vaginal white blood cells or mueopus has a high sensitivity (88.9%), but a low specificity (19.4%) for the diagnosis of upper genital-tract infection. Assessment of the lower genital tract for evidence of infection or inflammation is a valuable component of the diagnostic evaluation of pelvic inflammatory disease. The presence of either mucopus or vaginal white blood cells is a highly sensitive test for endometritis in patients with pelvic pain and tenderness. Infect. Dis. Obstet. Gynecol. 8:83–87, 2000.

Background: The primary objective of this study was to test and compare the efficacy of currently available intraoperative blood salvage systems via a demonstration of the level of increase in percentage concentration of red blood cells (RBC), white blood cells 9WBC) and platelets (Plt) in the end product. Methods: In a prospective, randomized study, data of 80 patients undergoing elective cardiac surgery with cardiopulmonary bypass in a 6-month period was collected, of which the volume aspirated from the surgical field was processed by either the HemoSep Novel Collection Bag (Advancis Surgical, Kirkby-in-Ashfield, Notts, UK) (N=40) (Group 1) or a cell- saver (C.A.T.S Plus Autotransfusion System, Fresenius Kabi, Bad Homburg, Germany) (N=40) (Group 2). Results: Hematocrit levels increased from 23.05%±2.7 to 43.02%±12 in Group 1 and from 24.5±2 up to 55.2±9 in Group 2 (p=0.013). The mean number of platelets rose to 225200±47000 from 116400 ±40000 in the HemoSep and decreased from 125200±25000 to 96500±30000 in the cell-saver group (p=0.00001). The leukocyte count was concentrated significantly better in Group 1 (from 10100±4300 to 18120±7000; p=0.001). IL-6 levels (pg/dL) decreased from 223±47 to 83±21 in Group 1 and from 219±40 to 200±40 in Group 2 (p=0.001). Fibrinogen was protected significantly better in the HemoSep group (from 185±35 to 455±45; p=0.004). Conclusions: Intraoperative blood salvage systems functioned properly and the resultant blood product was superior in terms of red blood cell species. The HemoSep group had significantly better platelet and leukocyte concentrations and fibrinogen content.

Abstract Backgrounds The occurrence of segmental/lobar pattern pneumonia (S/L-PP) in children increases with years. The pathogens of the disease may change for the abuse of antibiotics and the application of vaccines. Therefore, pathogens of S/L-PP in hospitalized children and their association with clinical characteristics may have changed. Objective: To analyze the pathogens of S/L-PP in hospitalized children and their association with clinical characteristics. Methods: The current study analyzed the epidemiological and clinical characteristics of pathogens in children with S/L-PP at a single hospital between 1st Jan 2014 and 31st Dec 2018 retrospectively. The pathogens and their associations with clinical characteristics were statistically analyzed. Results: A total of 593 children with S/L-PP received treatment at a single hospital during the study period by inclusion criteria. 451 patients were single positive for one pathogen and 83 patients had multiple infections. Mycoplasma pneumoniae (M.pneumoniae) (72.34%) was the most commonly detected pathogen, followed by streptococcus pneumoniae (S.pneumoniae) (8.77%). The infection of M.pneumoniae in children with S/L-PP increased with years (p<0.05). The positive rate of M.pneumoniae increased with ages of patients (p<0.05). M.pneumoniae was statistically associated to the extrapulmonary manifestations while S.pneumoniae was statistically associated with abnormal white blood cells (WBCs) and C reactive proteins (CRPs) (p<0.05). Conclusion: M.pneumoniae was the most positive pathogen in children with S/L-PP. The positive rate of M.pneumoniae in children with S/L-PP increased with years and the ages of children. M.pneumoniae was associated with extrapulmonary manifestations while S.pneumoniae was associated with abnormal WBCs and CRPs.

Abstract Backgrounds: The occurrence of segmental/lobar pattern pneumonia (S/L-PP) in children has recently increased. The pathogens of the disease may change due to the misuse of antibiotics and the application of vaccines. Therefore, pathogens of S/L-PP in hospitalized children and their association with clinical characteristics may have changed. Objective: To analyze the pathogens of S/L-PP in hospitalized children and their association with clinical characteristics. Methods: The current study analyzed the epidemiological and clinical characteristics of pathogens in children with S/L-PP under 14 years old at a single hospital between 1 st Jan 2014 and 31 st Dec 2018 retrospectively. The pathogens were detected by microbial cultivation, and/or indirect immunofluorescence of the kit (PNEUMOSLIDE IgM), and/or ELISA, and/or realtime PCR in the samples of the patients. Results: A total of 593 children with S/L-PP received treatment at a single hospital during the study period by inclusion criteria. 451 (76.05%) patients were single positive for one pathogen and 83 (14.00%) patients had multiple infections. Mycoplasma pneumoniae ( M.pneumoniae ) (72.34%) was the most frequently identified pathogen, followed by Streptococcus pneumoniae ( S.pneumoniae ) (8.77%). The infection of M.pneumoniae in children with S/L-PP increased with time (p<0.05). The positive rate of M.pneumoniae increased with ages of patients (p<0.05). M.pneumoniae was statistically associated with extrapulmonary manifestations while S.pneumoniae was statistically associated with abnormal white blood cells (WBCs) and C reactive proteins (CRPs) (p<0.05). Conclusion: M.pneumoniae was the most frequently identified pathogen in children with S/L-PP. The positive rate of M.pneumoniae in children with S/L-PP increased with time and the ages of children. M.pneumoniae was associated with extrapulmonary manifestations while S.pneumoniae was associated with abnormal WBCs and CRPs.
