Sensitivity, specificity, and predictive values of three Salmonella rapid detection kits using fresh and frozen poultry environmental samples versus those of standard plating. (1/3340)

To reduce human exposure to Salmonella spp. in poultry products, broiler chicken flocks have been tested by culture methods. Since the standard techniques may take 3 to 5 days, rapid detection methods have been developed. In this study we tested the performance of three rapid tests originally developed for food samples by using environmental samples obtained from poultry houses. These rapid tests were Reveal, an enzyme-linked immunosorbent assay from Neogen Corp.; BIND, a bacterial ice nucleation detection method from Idetek Corp.; and a filter monitor method from Future Medical Technologies, Inc. For the standard culture, brilliant green with novabiocin and xylose-lysine-tergitol-4 agar were used for presumptive identification, and identities were confirmed by using poly-O antisera. Environmental samples were collected from farms belonging to an integrated poultry company prior to chick placement and 1 week before slaughter. Sensitivities, specificities, and predictive values with 95% confidence intervals were calculated. Statistical differences were determined by using McNemar's chi square test. The sensitivities of the different tests were not stable, varying widely between sample times, and were affected by freezing of the samples. All of the rapid tests had low sensitivities, which led to many false-negative results. All tests were able to detect Salmonella spp. at a concentration of 10 CFU/ml in at least one of four trials. The BIND and Reveal tests were simple to use with multiple samples and reduced laboratory time by up to 1 day. Based on our results, we do not recommend that any of these rapid tests, in their present state of development, be utilized with environmental samples collected with drag swabs.  (+info)

Bacteriophage inactivation at the air-water-solid interface in dynamic batch systems. (2/3340)

Bacteriophages have been widely used as surrogates for human enteric viruses in many studies on virus transport and fate. In this investigation, the fates of three bacteriophages, MS2, R17, and phiX174, were studied in a series of dynamic batch experiments. Both MS2 and R17 readily underwent inactivation in batch experiments where solutions of each phage were percolated through tubes packed with varying ratios of glass and Teflon beads. MS2 and R17 inactivation was the result of exposure to destructive forces at the dynamic air-water-solid interface. phiX174, however, did not undergo inactivation in similar studies, suggesting that this phage does not accumulate at air-water interfaces or is not affected by interfacial forces in the same manner. Other batch experiments showed that MS2 and R17 were increasingly inactivated during mixing in polypropylene tubes as the ionic strength of the solution was raised (phiX174 was not affected). By the addition of Tween 80 to suspensions of MS2 and R17, phage inactivation was prevented. Our data suggest that viral inactivation in simple dynamic batch experiments is dependent upon (i) the presence of a dynamic air-water-solid interface (where the solid is a hydrophobic surface), (ii) the ionic strength of the solution, (iii) the concentration of surface active compounds in the solution, and (iv) the type of virus used.  (+info)

Quantitative study of the variability of hepatic iron concentrations. (3/3340)

BACKGROUND: The hepatic iron concentration (HIC) is widely used in clinical practice and in research; however, data on the variability of HIC among biopsy sites are limited. One aim of the present study was to determine the variability of HIC within both healthy and cirrhotic livers. METHODS: Using colorimetric methods, we determined HIC in multiple large (microtome) and small (biopsy-sized) paraffin-embedded samples in 11 resected livers with end-stage cirrhosis. HIC was also measured in multiple fresh samples taken within 5 mm of each other ("local" samples) and taken at sites 3-5 cm apart ("remote" samples) from six livers with end-stage cirrhosis and two healthy autopsy livers. RESULTS: The within-organ SD of HIC was 13-1553 microg/g (CV, 3.6-55%) for microtome samples and 60-2851 microg/g (CV, 15-73%) for biopsy-sized samples. High variability of HIC was associated with mild to moderate iron overload, because the HIC SD increased with increasing mean HIC (P <0.002). Livers with mean HIC >1000 microg/g exhibited significant biological variability in HIC between sites separated by 3-5 cm (remote sites; P <0.05). The SD was larger for biopsy-sized samples than for microtome samples (P = 0.02). CONCLUSION: Ideally, multiple hepatic sites would be sampled to obtain a representative mean HIC.  (+info)

Mailed, home-obtained urine specimens: a reliable screening approach for detecting asymptomatic Chlamydia trachomatis infections. (4/3340)

The use of mailed, home-obtained urine specimens could facilitate screening programs for the detection of asymptomatic Chlamydia trachomatis infections. Since transport time could have an adverse effect on the sensitivity of C. trachomatis detection by PCR, the influence of DNA degradation on amplification was monitored over the course of 1 week. Therefore, urine specimens were aliquoted on the day of collection or arrival. Two groups of urine specimens were investigated. Group I contains first-void C. trachomatis-positive and -negative urine samples. DNA degradation was monitored in group I samples for 7 days at room temperature (RT) and at 4 degrees C by amplifying different lengths of the human beta-globin gene and the C. trachomatis plasmid target. DNA degradation was observed only for the larger human beta-globin fragments at days 5 to 7 at RT. In contrast, at 4 degrees C all targets could be amplified. Urine specimens were also frozen and thawed before aliquoting to mimic freezing during transport. This resulted in a lower sensitivity for the detection of C. trachomatis after thawing and 3 to 4 days at RT. In addition, mailed, home-obtained C. trachomatis-positive urine specimens (group II) were analyzed for 7 days after arrival by two commercially available C. trachomatis detection systems (PCR and ligase chain reaction [LCR]). The C. trachomatis plasmid target in mailed, home-obtained urine specimens could be amplified by both PCR and LCR after 1 week of storage and/or transport at RT. In conclusion, our findings indicate that mailed, home-obtained urine specimens are suitable for the sensitive detection of asymptomatic C. trachomatis infections by amplification methods, even if the transport time is up to 1 week at RT. These findings support the feasibility and validity of screening programs based on mailed, home-obtained urine specimens. Larger studies should be initiated to confirm our results.  (+info)

European interlaboratory comparison of breath 13CO2 analysis. (5/3340)

The BIOMED I programme Stable Isotopes in Gastroenterology and Nutrition (SIGN) has focused upon evaluation and standardisation of stable isotope breath tests using 13C labelled substrates. The programme dealt with comparison of 13C substrates, test meals, test conditions, analysis techniques, and calculation procedures. Analytical techniques applied for 13CO2 analysis were evaluated by taking an inventory of instrumentation, calibration protocols, and analysis procedures. Two ring tests were initiated measuring 13C abundances of carbonate materials. Evaluating the data it was found that seven different models of isotope ratio mass spectrometers (IRMS) were used by the participants applying both the dual inlet system and the continuous flow configuration. Eight different brands of certified 13C reference materials were used with a 13C abundance varying from delta 13CPDB -37.2 to +2.0/1000. CO2 was liberated from certified material by three techniques and different working standards were used varying from -47.4 to +0.4/1000 in their delta 13CPDB value. The standard deviations (SDs) found for all measurements by all participants were 0.25/1000 and 0.50/1000 for two carbonates used in the ring tests. The individual variation for the single participants varied from 0.02 /1000 (dual inlet system) to 0.14/1000 (continuous flow system). The measurement of the difference between two carbonates showed a SD of 0.33/1000 calculated for all participants. Internal precision of IRMS as indicated by the specifications of the different instrument suppliers is < 0.3/1000 for continuous flow systems. In this respect it can be concluded that all participants are working well within the instrument specifications even including sample preparation. Increased overall interlaboratory variation is therefore likely to be due to non-instrumental conditions. It is possible that consistent differences in sample handling leading to isotope fractionation are the causes for interlaboratory variation. Breath analysis does not require sample preparation. As such, interlaboratory variation will be less than observed for the carbonate samples and within the range indicated as internal precision for continuous flow instruments. From this it is concluded that pure analytical interlaboratory variation is acceptable despite the many differences in instrumentation and analytical protocols. Coordinated metabolic studies appear possible, in which different European laboratories perform 13CO2 analysis. Evaluation of compatibility of the analytical systems remains advisable, however.  (+info)

Morbidity and cost-effectiveness analysis of outpatient analgesia versus general anaesthesia for testicular sperm extraction in men with azoospermia due to defects in spermatogenesis. (6/3340)

The outcome and costs of testicular sperm extraction under outpatient local analgesia or general anaesthesia were compared in men with non-obstructive azoospermia. Nineteen consecutive patients were allocated to receive general anaesthesia, while the subsequent 21 consecutive patients received outpatient analgesia in the form of i.v. midazolam sedation, lignocaine spray, scrotal infiltration with local anaesthetic and spermatic cord block. Blood pressure, pulse rate and respiratory rate were determined. Sedation and testicular pain were assessed by subjective scoring. Both groups showed haemodynamic stability with little alteration in blood pressure, pulse rate and oxygen saturation. Toxic symptoms of local anaesthetic were not encountered in the outpatient group. No relationship was found between testicular size and the duration of the operation. The median postoperative pain intensity, sedation scores and analgesic requirements were significantly less in the outpatient group (P < 0.05). These advantages led to a shorter recovery time (P < 0.0001), 3-fold cheaper care and greater patient satisfaction (P < 0.0001) in the outpatient group.  (+info)

Propofol concentrations in follicular fluid during general anaesthesia for transvaginal oocyte retrieval. (7/3340)

Propofol (Diprivan) is an i.v. anaesthetic used for general anaesthesia. The purpose of this study was to measure the propofol concentration in arterial blood and follicular fluid in patients during transvaginal oocyte retrieval. After approval by the University Ethics Committee, 30 women participated in this prospective study. Following induction of anaesthesia with 0.5 mg alfentanil and 2 mg.kg-1 propofol i.v., a continuous infusion of propofol at 10 mg.kg-1.h-1 was used for maintenance of anaesthesia. Follicular fluid and arterial blood samples were aspirated simultaneously at fixed intervals during the surgical procedure and propofol assayed by high pressure liquid chromatography (HPLC). The mean follicular fluid concentration of propofol increased linearly with time from 0.10 +/- 0.02 microgram.ml-1 to 0.57 +/- 0.06 microgram.ml-1 and was strongly related to the cumulative dose of propofol administered. The absorption of propofol was time-dependent. There was no correlation between the concentration of propofol in the follicular fluid and the arterial blood concentration of the drug. In conclusion, a propofol-based anaesthetic technique resulted in significant concentrations of this agent in follicular fluid, related to the dose administered and to the duration of propofol administration.  (+info)

Induction of macrophage migration inhibitory factor in human ovary by human chorionic gonadotrophin. (8/3340)

The role of macrophage migration inhibitory factor (MIF) in human ovarian function remains obscure. The aim of this study was to investigate how MIF was related to ovulation by quantitative analysis of serum, follicular fluid and culture medium of granulosa cells obtained from in-vitro fertilization (IVF) and embryo transfer patients. Serum MIF concentrations in ovarian stimulation cycles for IVF-embryo transfer were higher at day 1 (median 92.6 ng/ml), which took place 35 h after human chorionic gonadotrophin (HCG) administration and just before the retrieval of oocytes, than those before day -6 (12.1 ng/ml), at day -5 to about day 0 (17.5 ng/ml) or at day 2 to about day 14 (8.2 ng/ml). MIF concentrations in the follicular fluid (113.4 ng/ml) obtained in ovarian stimulation cycles for IVF-embryo transfer were significantly higher than in serum (72.0 ng/ml) collected at the same time. MIF concentrations in the follicular fluid in natural cycles were higher in the ovulatory phase (51.6 ng/ml) than in the late follicular phase (13.8 ng/ml). MIF concentrations in the culture media of granulosa cells increased from 3.2 ng/ml to 7.2 ng/ml with HCG stimulation, and decreased from 2.4 ng/ml to 1.2 ng/ml when stimulation was withheld. These results indicate that HCG can induce the elevation of serum and follicular fluid MIF concentrations through the stimulation of ovarian cells, and that MIF is probably involved in the mechanism of ovulation.  (+info)

Specimen handling is a set of procedures and practices followed in the collection, storage, transportation, and processing of medical samples or specimens (e.g., blood, tissue, urine, etc.) for laboratory analysis. Proper specimen handling ensures accurate test results, patient safety, and data integrity. It includes:

1. Correct labeling of the specimen container with required patient information.
2. Using appropriate containers and materials to collect, store, and transport the specimen.
3. Following proper collection techniques to avoid contamination or damage to the specimen.
4. Adhering to specific storage conditions (temperature, time, etc.) before testing.
5. Ensuring secure and timely transportation of the specimen to the laboratory.
6. Properly documenting all steps in the handling process for traceability and quality assurance.

A Pathology Department in a hospital is a division that is responsible for the examination and diagnosis of diseases through the laboratory analysis of tissue, fluid, and other samples. It plays a crucial role in providing accurate diagnoses, treatment planning, and monitoring of patients' health statuses. The department is typically staffed by pathologists (physicians who specialize in interpreting medical tests and diagnosing diseases), as well as laboratory technologists, technicians, and assistants.

The Pathology Department provides various services, including:

1. Anatomical Pathology - Examination of tissue specimens to identify abnormalities, such as cancerous growths or other diseases. This includes surgical pathology, cytopathology (examining individual cells), and autopsy pathology.
2. Clinical Pathology - Analysis of bodily fluids, such as blood, urine, and cerebrospinal fluid, to assess chemical, hematological, immunological, and microbiological aspects. This includes hematology (study of blood cells), clinical chemistry (analysis of body chemicals), immunopathology (study of immune system disorders), and microbiology (identification and classification of bacteria, viruses, fungi, and parasites).
3. Molecular Pathology - Analysis of DNA, RNA, and proteins to identify genetic mutations or abnormalities that contribute to diseases, particularly cancer. This information can help guide targeted therapies and personalized treatment plans.
4. Forensic Pathology - Examination of bodies to determine the cause and manner of death in cases of suspected criminal activity, accidents, or other suspicious circumstances.

The Pathology Department's work is essential for providing accurate diagnoses, determining appropriate treatments, monitoring disease progression, and conducting medical research.
