PCA3 as a second-line biomarker in a prospective controlled randomized opportunistic prostate cancer screening programme

2017

Objectives: PCA3 performance as a single second line biomarker is compared to the European Randomised Study of Screening for Prostate Cancer risk calculator model 3 (ERSPC RC-3) in an opportunistic screening in prostate cancer (PCa). Material and methods: 5,199 men, aged 40-75y, underwent prostate-specific antigen (PSA) screening and digital rectal examination (DRE). Men with a normal DRE and PSA >= 3 ng/ml had a PCA3 test done. All men with PCA3 >= 35 underwent an initial biopsy (IBx) 12 cores. Men with PCA3 = 3 ng/ml and DRE is normal, IBx could be avoided in 12.5% less than if ERSPC RC-3 is used and would reduce the false negative cases by 36.2%. At a FU of 21.7 months, this dual protoco…

Detection of Mycoplasma sp. in bronchoalveolar lavage of AIDS patients with pulmonary infiltrates.

1996

We examined 486 bronchoalveolar lavages (BAL) including 32 from AIDS patients with pulmonary infiltrates and 20 from patients with leukemia or after transplantation. Mycoplasmas were found in 4/32 (12.5%) HIV-positive patients compared to 4/454 (0.9%) HIV-negative patients (p0.001). All of these four HIV-positive patients suffered from advanced infection (CD4 counts100/microL) and developed complications (Pcp, n = 2, recurrent bacterial pneumonia, n = 1, pulmonary Kaposi sarcoma, n = 1). No mycoplasmas were detected in 20 immunosuppressed patients with leukemia or after transplantation. Our data indicate that AIDS patients may be more often colonised or infected by mycoplasmas than HIV-nega…

A macrophage-suppressing 40-kD protein in a case of pulmonary alveolar proteinosis.

1987

Pulmonary alveolar proteinosis (PAP) is a rare disease of unknown etiology. Macrophage dysfunctions are claimed to be involved in the pathogenesis. We investigated phagocytosis and oxidative metabolism of alveolar macrophages in a case of pulmonary alveolar proteinosis. These cells phagocytize normally and phagocytizable stimulants cause a normal oxidative burst. In response to the membrane signals phorbolmyristate acetate and aggregated immunoglobulin, however, no stimulated turnover of the oxidative metabolism can be observed. A 40-kD protein found in the lavage fluid mediates this macrophage-inhibiting effect. This phenomenon may contribute to the frequent opportunistic infections seen i…

Posaconazole or Fluconazole for Prophylaxis in Severe Graft-versus-Host Disease

2007

Invasive fungal infections are an important cause of morbidity and mortality after allogeneic hematopoietic stem-cell transplantation.In an international, randomized, double-blind trial, we compared oral posaconazole with oral fluconazole for prophylaxis against invasive fungal infections in patients with graft-versus-host disease (GVHD) who were receiving immunosuppressive therapy. The primary end point was the incidence of proven or probable invasive fungal infections from randomization to day 112 of the fixed treatment period of the study.Of a total of 600 patients, 301 were assigned to posaconazole and 299 to fluconazole. At the end of the fixed 112-day treatment period, posaconazole wa…

The Penile Plication Procedure: An Alternative Method for Straightening Penile Deviation

1991

AbstractThe number of reported cases of congenital and acquired penile deviation is evidently increasing. We describe our experience with the penile plication procedure, which we used to treat 40 patients with penile deviation. Postoperatively, all patients regained the ability for sexual intercourse, with potency remaining unimpaired. Of the patients 96% were completely satisfied with the result of the operation. Sustained complications have not been observed. To avoid major trauma the surgical intervention should not include removal of ellipsoids from the penile tunica albuginea as proposed by Nesbit. Since the penile plication method produces equally good results in terms of performance …

BYOTYPES AND RANDOMLY AMPLIFIED POLYMORPHIC DNA (RAPD) PROFILES OF SUBGINGIVAL CANDIDA ALBICANS ISOLATES IN HIV INFECTION

2005

ABSTRACT: A group of subgingival isolates of C. albicans recovered from Italian HIV-positive (HIV+) subjects were characterized both phenotypically and genotypically. Phenotyping of the isolates was carried out by a biotyping method based on the enzyme profiles, carbohydrate assimilation patterns and boric acid resistance of the yeasts. Genotyping was performed through randomly amplified polymorphic DNA (RAPD) analysis. Five biotypes were found among the 29 subgingival C. albicans strains examined. The predominant biotypes were A1R (55.17%), A1S (24.14%), and A2R (13.79%), while the biotypes A11R and A13R were represented by a single isolate each. RAPD profiles identified 15 genotypes among…

Immunohistochemical analysis of vascular endothelial growth factor (VEGF) and p53 expression in pterygium from Tunisian patients.

2009

A pterygium is characterized by abnormal fibrovascular corneoconjunctival tissue. A number of investigations have attempted to elucidate this incompletely understood pathology. Since vascular endothelial growth factor (VEGF) and p53 are known to participate in tumor vascularization, our purpose was to study VEGF and p53 expression in active primary and recurrent pterygium from Tunisian patients. To this end, 15 cases of active primary pterygium and five cases of recurrent pterygium from Tunisia were studied by immunohistochemistry. Antibodies raised against VEGF and p53 were used to analyze the distribution and expression of these markers in pterygium and normal human conjunctiva were used …

Clinical features and epidemiology of cutaneous leishmaniasis and Leishmania major/HIV co-infection in Cameroon: results of a large cross-sectional s…

2011

Cutaneous leishmaniasis (CL) is endemic in Central Africa, including Cameroon. However, data on its prevalence and co-infection with HIV are scarce. Here we present the results of a large cross-sectional study reporting the prevalence, clinical features and species identification of CL and HIV co-infection in northern Cameroon. A total of 32 466 subjects were clinically screened for CL during a door-to-door survey, followed by parasitological diagnosis in the field laboratory. Amongst the subjects surveyed, 146 (0.4%) were diagnosed with active CL. Seven (4.8%) of these 146 CL patients tested positive for HIV-1 and/or HIV-2. The number of lesions per CL patient ranged from 1 to 20. Three of…

Long-term effects of a multidisciplinary treatment of uncomplicated obesity on carotid intima-media thickness

2011

Obesity is associated with well-known cardiovascular risk factors and a lower life expectancy. This study investigated whether nonoperative nutritional treatment of obesity without comorbidities influenced the carotid intima-media thickness (c-IMT) in the long run. Fifty-four subjects of an original cohort of 251 subjects were re-evaluated 10 years after a medical nutritional treatment (MNT) with cognitive-behavioral approach for uncomplicated obesity. Forty subjects were classified as failure (10-year body weight change >0.5 kg) and 14 (body weight change ≤0.5 kg) as a success of the MNT. Ten years after MNT, c-IMT significantly increased (0.06 ± 0.02 mm; P = 0.004) in the failure group an…
