Cohort study of art glass workers in Tuscany, Italy: mortality from non-malignant diseases. (1/155)
This investigation studies cause-specific mortality of art glass workers employed in 17 industrial facilities in Tuscany, Italy. A cohort of 3,390 workers employed for at least 1 year was enumerated from company payrolls. Follow-up was between the start of employment in each factory and 31 December 1993. The cause-specific expected mortality was computed relative to Tuscany rates and specified for gender, 5-year age groups and calendar year. Separate analyses were carried out for the jobs of makers and formers and for batch mixers. Among males (3, 180 individuals) observed mortality for non-cancer causes was higher than expected for hypertensive disease [standardized mortality ratio (SMR) = 178, 90% confidence interval (90% CI) = 96-301], pneumoconiosis (SMR = 200, 90% CI = 94-376) and diseases of the genitourinary system (SMR = 169, 90% CI = 95-279). Increases for the above causes were shown also among makers and formers: hypertensive disease (SMR = 182, 90% CI = 85-341), pneumoconiosis (SMR = 250, 90% CI = 109-493) and diseases of the genitourinary system (SMR = 224, 90% CI = 121-380). For batch mixers an increase was present for cerebrovascular disease. The observed mortality for cancer causes was above the expected for cancers of the larynx, lung, stomach and brain. This study points to the existence for Tuscan glass workers of health effects in addition to cancer; previously observed carcinogenic effects were also confirmed. (+info)Induction of HLA class I-restricted CD8+ CTLs specific for the major outer membrane protein of Chlamydia trachomatis in human genital tract infections. (2/155)
HLA class I-restricted CD8+ CTLs specific for the major outer membrane protein (MOMP) of Chlamydia trachomatis are present in the peripheral blood of humans who acquired genital tract infections with the organism. Three HLA-A2-restricted epitopes and two HLA-B51-restricted epitopes were identified in serovar E-MOMP. One of the five epitopes spans a variable segment of MOMP and is likely a serovar E-specific epitope. The other four epitopes are localized in constant segments and are C. trachomatis species specific. CTL populations specific for one or more of the four constant segment epitopes were isolated from all 10 infected subjects tested, regardless of infecting serovars, but from only one of seven uninfected subjects tested. The CTLs failed to recognize corresponding peptides derived from Chlamydia pneumoniae MOMP, further suggesting that they indeed resulted from genital tract infections with C. trachomatis. Significantly, ME180 human cervical epithelial cells productively infected with C. trachomatis were killed by the MOMP peptide-specific CTLs. Further investigations of the ability of such CTLs to lyse normal infected epithelial cells and their presence at inflamed sites in the genital tract will help understand the protective or pathological role of CTLs in chlamydial infections. The MOMP CTL epitopes may be explored as potential components of a subunit vaccine against sexually transmitted diseases caused by C. trachomatis. Moreover, the knowledge provided here will facilitate studies of HLA class I pathways of chlamydial Ag processing and presentation in physiologically relevant human APCs. (+info)Mortality from nonmalignant diseases of the respiratory, genitourinary and nervous systems among workers exposed to styrene in the reinforced plastics and composites industry in the United States. (3/155)
OBJECTIVES: Mortality from diseases of the nervous system and nonmalignant diseases of the respiratory and genitourinary systems was examined for workers exposed to styrene. METHODS: Altogether 15,826 styrene-exposed workers in 30 plants in the reinforced plastics and composites industry were included. Vital status was ascertained through 31 December 1989. Individual exposure estimates were developed based on job functions, existing industrial hygiene data, process changes, engineering controls, work practices, and the use of personal protective equipment. Analyses were based on cause-specific standardized mortality ratios (SMR) and the Cox proportional hazards model. Mortality data were analyzed by latency, duration of exposure, average exposure, cumulative exposure, and process category. RESULTS: For diseases of the nervous system, the SMR was 0.56 [95% confidence interval (95% CI) 0.31-0.95]. Mortality from nonmalignant genitourinary diseases was not increased (SMR 0.87, 95% CI 0.46-1.50). Latency, duration of exposure, average exposure, cumulative exposure, and process category showed no association between styrene exposure and these 2 types of disease. A small increase in mortality from nonmalignant respiratory diseases was found (SMR 1.21, 95% CI 0.98-1.47), mainly due to "other nonmalignant respiratory diseases" (SMR 1.40, 95% CI 1.04-1.84). The highest increase occurred for short exposure duration (SMR 1.79 for <1 year's exposure) or low exposure (SMR 2.15 for <10 ppm-years); there were no increased risks in the high exposure categories. The Cox proportional hazard model revealed no association between styrene exposure and the diseases. CONCLUSIONS: No relationship was found between mortality from any of the diseases examined and any of the styrene exposure indices. The findings were compared with those reported in a European study of styrene-exposed workers. (+info)Creatinine at the evaluation of urinary 1-methyladenosine and pseudouridine excretion. (4/155)
The elevation of urinary modified nucleosides levels in urine is found in patients with cancers. In the present study, we have tested 616 urine samples randomly collected from non-malignant cases. Thirty-two percent (194/616) and 11% (68/616) had elevated levels of 1-methyladenosine and pseudouridine, respectively (They are designated as false-positive cases). To elucidate the cause on non-specific elevation of the nucleosides, the correlation between creatinine excretion level and urinary nucleosides levels were determined. The result revealed that false-positive cases were frequently detected in patients with lower creatinine excretion levels. The mean creatinine levels of false-positive cases were significantly lower than those of negative cases. From these results, the false-positive of urinary 1-methyladenosine and pseudouridine might be due to the low creatinine excretion mainly caused by the renal dysfunction. Creatinine excretion in each individual should be taken into consideration in case of determining urinary modified nucleosides. (+info)Etiology of genital ulcer disease in Dakar, Senegal, and comparison of PCR and serologic assays for detection of Haemophilus ducreyi. (5/155)
We used PCR assays to determine the etiology of genital ulcers in patients presenting to a sexually transmitted disease clinic in Dakar, Senegal, and evaluated the ability of two PCR tests (groEL and recD) and two serological tests (adsorption enzyme immunoassay [EIA] and lipooligosaccharide [LOS] EIA) to detect current Haemophilus ducreyi infection. We found that in this population, H. ducreyi, T. pallidum, and herpes simplex virus HSV DNA were detected in 56, 15, and 13% of 39 genital ulcer specimens, respectively, and H. ducreyi DNA was detected in 60% (3 of 5) of samples from ulcerated bubos. Among 40 consecutive patients with genital ulcer disease and with sufficient sample for both PCR assays, the recD and groEL H. ducreyi PCR assays were 83% concordant, with the recD PCR assay detecting six (15%) additional positive specimens and the groEL assay detecting one (3%) additional positive specimen. Compared to PCR, the adsorption EIA and LOS EIA tests had sensitivities of 71 and 59% and specificities of 57 and 90%, respectively, for the diagnosis of current H. ducreyi infection. While these differences in specificity could be due either to previous infection with H. ducreyi or to the detection of cross-reacting antibodies, only 6% of patients from a nearby family planning clinic gave a positive reaction in both the adsorption EIA and LOS EIA assays, indicating that cross-reacting antibodies are not prevalent among clinic attendees in this city. Our studies indicate that the adsorption EIA detects both current and past infection, while the LOS EIA assay is more specific for current infection with H. ducreyi in this population. (+info)Results of a phase II study using estramustine phosphate and vinblastine in combination with high-dose three-dimensional conformal radiotherapy for patients with locally advanced prostate cancer. (6/155)
PURPOSE: To assess the feasibility and tolerance of neoadjuvant and concomitant estramustine phosphate and vinblastine (EV) with high-dose three-dimensional conformal radiotherapy (3D-CRT) for patients with unfavorable-risk prostate cancer. PATIENTS AND METHODS: Twenty-seven patients with unfavorable-risk prostate cancer were enrolled onto a prospective study to determine the feasibility of combining EV with 3D-CRT. Patients were eligible if any of the following requirements were satisfied: (1) Gleason score > or =8 and prostate-specific antigen (PSA) > 10 ng/mL; (2) Gleason score of 7 and PSA > 20 ng/mL; (3) clinical stage T3N0M0 disease with PSA > 20 ng/mL; (4) any patient with T4N0M0 disease; or (5) patients with TXN1MO disease. Therapy consisted of three 8-week cycles of EV and 8 weeks of 3D-CRT. Estramustine phosphate was given orally beginning on week 1 and continued until the completion of 3D-CRT. Each 8-week cycle of vinblastine consisted of 6 weekly intravenous injections followed by a 2-week rest period. Radiation therapy was administered using a three-dimensional conformal approach to a prescription dose of 75.6 Gy. The median follow-up was 26 months (range, 6 to 40 months). RESULTS: Twenty-three (85%) of 27 patients completed the entire course of therapy and were assessable for toxicities and biochemical outcome. Two patients (7%) developed grade 3 hematologic toxicity that resolved, and two patients (7%) developed grade 3 hepatoxicity, manifesting as persistent elevation of serum transaminase levels, necessitating discontinuation of the chemotherapy and withdrawal from the treatment program. The most prominent adverse effects from this regimen were mild to moderate (grade 1 to 2) nausea and fatigue related to estramustine. Mild peripheral edema was seen in 15% of patients and was treated with diuresis. 3D-CRT was tolerated well in these patients. Medications were required for relief of acute grade 2 rectal (gastrointestinal [GI]) and urinary (genitourinary [GU]) symptoms in 35% and 48% of patients, respectively. Three patients developed acute grade 3 GU toxicities. The 2-year actuarial likelihood of late grade 2 GI toxicity was 20%. No late grade 3 or 4 GI toxicities were observed. The 2-year actuarial likelihoods of late grade 2 and 3 GU toxicities were 25% and 12%, respectively. No grade 4 GU toxicity was observed. CONCLUSION: Neoadjuvant and concomitant EV with high-dose 3D-CRT is well tolerated in patients with unfavorable-risk prostate cancer. Although the incidence of modest (grade 2) late GI and GU toxicities seem to be increased compared with 3D-CRT alone or in combination with androgen ablation therapy, no severe toxicities were encountered with this regimen. (+info)Detection of Chlamydia trachomatis-specific antibodies in human sera by recombinant major outer-membrane protein polyantigens. (7/155)
This study was performed to generate and evaluate recombinant antigens for use in a species-specific Chlamydia trachomatis immunoassay. In a molecular genetic approach, fragments of the C. trachomatis major outer-membrane protein (MOMP) were produced as fusion proteins to create three different constructs encompassing the variable domains I, II and IV of selected C. trachomatis serovars. The recombinant MOMP polyantigens were affinity-purified and used in an enzyme-linked immunosorbent assay. Antibody detection was evaluated with 103 patient sera and the results were compared with titres obtained in the micro-immunofluorescence test. The results showed that the generated MOMP polyantigens detected the presence of C. trachomatis-specific human antibodies with little cross-reaction to C. pneumoniae-specific antibodies. When compared to the micro-immunofluorescence assay the MOMP polyantigen detected the presence of anti-C. trachomatis IgG antibodies with a sensitivity of 80% and a specificity of 91%. (+info)Urogenital Chlamydia trachomatis serovars in men and women with a symptomatic or asymptomatic infection: an association with clinical manifestations? (8/155)
To determine whether certain Chlamydia trachomatis serovars are preferentially associated with a symptomatic or an asymptomatic course of infection, C. trachomatis serovar distributions were analyzed in symptomatically and asymptomatically infected persons. Furthermore, a possible association between C. trachomatis serovars and specific clinical symptoms was investigated. C. trachomatis-positive urine specimens from 219 asymptomatically infected men and women were obtained from population-based screening programs in Amsterdam. Two hundred twenty-one C. trachomatis-positive cervical and urethral swabs from symptomatically and asymptomatically infected men and women were obtained from several hospital-based departments. Serovars were determined using PCR-based genotyping, i.e., restriction fragment length polymorphism analysis of the nested-PCR-amplified omp1 gene. The most prevalent C. trachomatis serovars, D, E, and F, showed no association with either a symptomatic or asymptomatic course of infection. The most prominent differences found were (i) the association of serovar Ga with symptoms in men (P = 0.0027), specifically, dysuria (P < 0.0001), and (ii) detection of serovar Ia more often in asymptomatically infected people (men and women) (P = 0.035). Furthermore, in women, serovar K was associated with vaginal discharge (P = 0.002) and serovar variants were found only in women (P = 0.045). (+info)"Male urogenital diseases" refer to a range of medical conditions that affect the urinary and reproductive systems in males. This can include:
1. Benign Prostatic Hyperplasia (BPH): An enlarged prostate gland that can cause difficulties with urination.
2. Prostatitis: Inflammation of the prostate gland, which can cause pain, urinary frequency and difficulty, and sexual dysfunction.
3. Erectile Dysfunction (ED): The inability to achieve or maintain an erection sufficient for sexual activity.
4. Peyronie's Disease: A condition where scar tissue causes the penis to bend or curve during an erection.
5. Testicular Cancer: A malignant tumor that develops in the testicle.
6. Epididymitis: Inflammation of the epididymis, a coiled tube at the back of the testicle where sperm matures.
7. Orchitis: Inflammation of the testicle, often caused by an infection.
8. Urinary Tract Infections (UTIs): Bacterial infections that can occur anywhere along the urinary tract.
9. Kidney Stones: Small, hard mineral deposits that form in the kidneys and can cause severe pain when passed.
10. Bladder Cancer: A malignant tumor that develops in the bladder.
These conditions can vary greatly in severity and treatment, so it's important for individuals to seek medical advice if they suspect they may have a urogenital disease.
Female urogenital diseases refer to a range of medical conditions that affect the female urinary and genital systems. These systems include the kidneys, ureters, bladder, urethra, vulva, vagina, and reproductive organs such as the ovaries and uterus.
Some common female urogenital diseases include:
1. Urinary tract infections (UTIs): These are infections that occur in any part of the urinary system, including the kidneys, ureters, bladder, or urethra.
2. Pelvic inflammatory disease (PID): This is an infection of the reproductive organs, including the uterus, fallopian tubes, and ovaries.
3. Endometriosis: This is a condition in which tissue similar to the lining of the uterus grows outside of the uterus, often on the ovaries, fallopian tubes, or other pelvic structures.
4. Ovarian cysts: These are fluid-filled sacs that form on the ovaries.
5. Uterine fibroids: These are noncancerous growths that develop in the muscular wall of the uterus.
6. Interstitial cystitis/bladder pain syndrome (IC/BPS): This is a chronic bladder condition characterized by pain, pressure, and discomfort in the bladder and pelvic area.
7. Sexually transmitted infections (STIs): These are infections that are passed from person to person during sexual contact. Common STIs include chlamydia, gonorrhea, syphilis, and HIV.
8. Vulvodynia: This is chronic pain or discomfort of the vulva, the external female genital area.
9. Cancers of the reproductive system, such as ovarian cancer, cervical cancer, and uterine cancer.
These are just a few examples of female urogenital diseases. It's important for women to receive regular medical care and screenings to detect and treat these conditions early, when they are often easier to manage and have better outcomes.
'Female urogenital diseases' refer to a range of medical conditions that affect the urinary and reproductive systems in women. These may include:
1. Urinary Tract Infections (UTIs): These are infections that occur in any part of the urinary system, including the kidneys, bladder, ureters, and urethra.
2. Kidney Stones: These are small, hard deposits that form inside the kidneys when there is a concentration of minerals and salts in the urine.
3. Pelvic Inflammatory Disease (PID): This is an infection of the reproductive organs in women, including the uterus, fallopian tubes, and ovaries.
4. Endometriosis: This is a condition where the tissue that lines the inside of the uterus grows outside of it, leading to pain, irregular bleeding, and infertility.
5. Ovarian Cysts: These are fluid-filled sacs that form on the ovaries and can cause pain and discomfort.
6. Uterine Fibroids: These are noncancerous growths that develop in or on the uterus, leading to heavy menstrual bleeding, pelvic pressure, and pain during sex.
