Comparison of a parasite lactate dehydrogenase-based immunochromatographic antigen detection assay (OptiMAL) with microscopy for the detection of malaria parasites in human blood samples. (1/410)

Microscopic examination of blood smears remains the gold standard for malaria diagnosis, but is labor-intensive and requires skilled operators. Rapid dipstick technology provides a potential alternative. A study was conducted in The Gambia to compare the performance of OptiMAL, an immunochromatographic antigen detection assay for the diagnosis of malaria using parasite lactate dehydrogenase, against standard microscopy in patients with suspected malaria. For initial diagnosis of Plasmodium falciparum, irrespective of stage, this assay had a sensitivity of 91.3%, a specificity of 92%, a positive predictive value of 87.2%, and a negative predictive value of 94.7%. The sensitivity of the test decreased markedly at parasitemias < 0.01%. This assay can be used for the diagnosis of malaria in areas where microscopy is not available and for urgent malaria diagnosis at night and at weekends, when routine laboratories are closed and when relatively inexperienced microscopists may be on duty.  (+info)

Comparison of five methods of malaria detection in the outpatient setting. (2/410)

In eastern Africa where 90% of the malaria is due to Plasmodium falciparum, the accuracy of malaria diagnosis at the outpatient level is becoming increasingly important due to problems of drug resistance and use of alternative, costly antimalarial drugs. The quantitative buffy coat (QBC) technique, acridine orange staining with an interference filter system, and the ParaSight-F test have been introduced as alternative methods to conventional microscopy for the diagnosis of malaria. Two hundred thirteen outpatients were tested using these alternative methods and conventional microscopy by five experienced technologists; two were randomly allocated to read the results of each test. Paired results showed the highest level of agreement with the ParaSight-F test (99%), followed by Field stain (92%). The results of the QBC technique showed the least agreement (73%). Using conventional microscopy as the reference standard, the ParaSight-F test had a sensitivity range of 90-92% and a specificity of 99%, staining with acridine orange had a sensitivity range of 77-96% and a specificity range of 81-98% and the QBC technique had a sensitivity range of 88-98% and a specificity range of 58-90%. All microscopic tests showed lower sensitivities (as low as 20% using staining with acridine orange) in detecting low parasitemias (< or = 320/microl) than the ParaSight-F test (70%). Due to the high cost of the ParaSight-F test, Field-stained blood films remain the most appropriate method for diagnosis of P. falciparum in eastern Africa. The ParaSight-F test may be used in situations where no trained microscopists are available, or where malaria is strongly suspected and the results of microscopy are negative.  (+info)

Renal assessment practices and the effect of nurse case management of health maintenance organization patients with diabetes. (3/410)

OBJECTIVE: To examine baseline renal screening practices and the effect of nurse case management of patients with diabetes in a group model health maintenance organization (HMO). RESEARCH DESIGN AND METHODS: We performed both 1-year retrospective and 1-year prospective studies of renal assessment practices and ACE inhibitor usage in a cohort of 133 diabetic patients enrolled in a randomized controlled trial of a diabetes nurse case management program in a group model HMO. In accordance with American Diabetes Association recommendations, urine dipstick and quantitative protein and microalbuminuria testing rates were calculated. RESULTS: At baseline, 77% of patients were screened for proteinuria with dipsticks or had quantitative urine testing. Of patients with negative dipstick findings, 30% had appropriate quantitative protein or microalbumin follow-up at baseline. Baseline ACE inhibitor usage was associated with decreased follow-up testing (relative risk = 0.47). Nurse case management was associated with increased quantitative protein or or microalbumin testing and increased follow-up testing (relative risk = 1.65 and 1.60, respectively). CONCLUSIONS: We found a higher degree of adherence to recommendations for renal testing than has been reported previously. Nurse case management intervention further increased renal screening rates. The inverse association between ACE inhibitor usage and microalbumin testing highlights a potentially ambiguous area of current clinical pathways.  (+info)

A comparative evaluation of Etest and broth microdilution methods for fluconazole and itraconazole susceptibility testing of Candida spp. (4/410)

The Etest strip is a promising tool of broad application in clinical microbiology. The method provides MIC readings and is easier to perform than broth microdilution. We carried out a study to compare the MICs of fluconazole and itraconazole obtained by the Etest with those obtained by broth microdilution, performed according to the guidelines of the NCCLS document M27-A, with 402 clinical isolates (360 Candida albicans, 17 Candida tropicalis, nine Candida krusei, nine Candida glabrata and seven Candida parapsilosis) and seven control isolates. The agreement between MICs by the two methods (at +/- 2 dilutions) was 74.5% for fluconazole and 61.4% for itraconazole. These results suggest that further development is necessary to standardize the medium and incubation conditions before introduction of the Etest as a routine method in the clinical microbiology laboratory for fluconazole and itraconazole susceptibility testing.  (+info)

Validity of interpretation criteria for standardized Western blots (immunoblots) for serodiagnosis of Lyme borreliosis based on sera collected throughout Europe. (5/410)

Western blotting (WB; immunoblotting) is a widely used tool for the serodiagnosis of Lyme borreliosis (LB), but so far, no generally accepted criteria for performance and interpretation have been established in Europe. The current study was preceeded by a detailed analysis of WB with whole-cell lysates of three species of Borrelia burgdorferi sensu lato (U. Hauser, G. Lehnert, R. Lobentanzer, and B. Wilske, J. Clin. Microbiol. 35:1433-1444, 1997). In that study, interpretation criteria for a positive WB result were developed with the data for 330 serum samples (from patients with LB in different stages [n = 189] and from a control group [n = 141]) originating mostly from southern Germany. In the present work, the interpretation criteria for strains PKo (Borrelia afzelii) and PBi (Borrelia garinii) developed in the previous study were reevaluated with 224 serum samples (from patients with LB in different stages [n = 97] and from a control group [n = 127]) originating from throughout Europe that were provided by the European Union Concerted Action on Lyme Borreliosis (EUCALB). De novo criteria were developed on the basis of the reactivities of the EUCALB sera and were evaluated with the data for the samples from southern Germany. Comparison of all results led to the following recommendations: For WB for immunoglobulin G (IgG), at least two bands among p83/100, p58, p43, p39, p30, OspC, p21, p17, and p14 for PKo and at least one band among p83/100, p39, p30, OspC, p21, and p17b for PBi; for WB for IgM, at least one band among p39, OspC, and p17 or a strong p41 band for PKo and at least one band among p39 and OspC or a strong p41 band for PBi. WB with PKo was the most sensitive, and this strain is recommended for use in WB for the serodiagnosis of LB throughout Europe.  (+info)

Evaluation of the pathotec Rapid I-D system for identification of Enterobacteriaceae. (6/410)

The PathoTec Rapid I-D System for identifying Enterobacteriaceae was evaluated with 471 cultures. In 4,910 individual test comparisons, 95.5% of the results agreed, with results of only two test strips, those for esculin hydrolysis and urease production, agreeing with conventional tests in less than 94% of the trials. The PathoTec system exhibited 94.3% accuracy in identifying these cultures in a double-blind study with conventional media and procedures as the alternate system. Two newly developed test strips, for 0-nitrophenyl-beta-D-galactopyranoside and ornithine decarboxylase, were found to be highly reliable.  (+info)

Evaluation of a rapid and inexpensive dipstick assay for the diagnosis of Plasmodium falciparum malaria. (7/410)

Rapid, accurate and affordable methods are needed for the diagnosis of malaria. Reported here is an evaluation of a new immunochromatographic strip, the PATH Falciparum Malaria IC Strip, which is impregnated with an immobilized IgM monoclonal antibody that binds to the HRP-II antigen of Plasmodium falciparum. In contrast to other commercially available kits marketed for the rapid diagnosis of falciparum malaria, this kit should be affordable in the malaria-endemic world. Using microscopy and polymerase chain reaction (PCR)-based methods as reference standards, we compared two versions of the PATH test for the detection of P. falciparum infection in 200 febrile travellers. As determined by PCR and microscopy, 148 travellers had malaria, 50 of whom (33.8%) were infected with P. falciparum. Compared with PCR, the two versions of the PATH test had initial sensitivities of 90% and 88% and specificities of 97% and 96%, respectively, for the detection of falciparum malaria. When discrepant samples were retested blindly with a modified procedure (increased sample volume and longer washing step) the sensitivity and specificity of both kits improved to 96% and 99%, respectively. The two remaining false negatives occurred in samples with < 100 parasites per microliter of blood. The accuracy, simplicity and predicted low cost may make this test a useful diagnostic tool in malaria-endemic areas.  (+info)

Evaluation of the one-minute ultra-rapid urease test for diagnosing Helicobacter pylori. (8/410)

To determine the diagnostic accuracy of the one-minute ultra-rapid urease test for diagnosing Helicobacter pylori infection, two biopsies were taken from both the gastric corpus and antrum from 1000 patients undergoing upper gastrointestinal endoscopy. All the biopsies were subjected to the one-minute ultra-rapid urease test before imprint smears were prepared from them. Thereafter, the biopsies were fixed in 10% formalin and histological sections were examined for the presence of H pylori by a pathologist who was not aware of the clinical details or the results of the urease test. The prevalence of H pylori in the gastric antrum and corpus was 86.7% and 53.3%, respectively. The sensitivity, specificity, positive and negative predictive value and the overall diagnostic accuracy of the ultra-rapid urease test to diagnose H pylori infection in the gastric antrum were 92%, 100%, 100%, 66%, and 93%, respectively. The corresponding figures for the gastric corpus were 83%, 100%, 100%, 85%, and 91%, respectively. It is concluded that the one-minute ultra-rapid urease test has a high sensitivity and specificity and may be used as a rapid and cheap method to diagnose H pylori infection.  (+info)

Reagent strips, also known as diagnostic or test strips, are narrow pieces of plastic material that have been impregnated with chemical reagents. They are used in the qualitative or semi-quantitative detection of various substances, such as glucose, proteins, ketones, blood, and white blood cells, in body fluids like urine or blood.

Reagent strips typically contain multiple pad areas, each with a different reagent that reacts to a specific substance. To perform the test, a small amount of the fluid is applied to the strip, and the reaction between the reagents and the target substance produces a visible color change. The resulting color can then be compared to a standardized color chart to determine the concentration or presence of the substance.

Reagent strips are widely used in point-of-care testing, providing quick and convenient results for healthcare professionals and patients alike. They are commonly used for monitoring conditions such as diabetes (urine or blood glucose levels), urinary tract infections (leukocytes and nitrites), and kidney function (protein and blood).

Indicators and reagents are terms commonly used in the field of clinical chemistry and laboratory medicine. Here are their definitions:

1. Indicator: An indicator is a substance that changes its color or other physical properties in response to a chemical change, such as a change in pH, oxidation-reduction potential, or the presence of a particular ion or molecule. Indicators are often used in laboratory tests to monitor or signal the progress of a reaction or to indicate the end point of a titration. A familiar example is the use of phenolphthalein as a pH indicator in acid-base titrations, which turns pink in basic solutions and colorless in acidic solutions.

2. Reagent: A reagent is a substance that is added to a system (such as a sample or a reaction mixture) to bring about a chemical reaction, test for the presence or absence of a particular component, or measure the concentration of a specific analyte. Reagents are typically chemicals with well-defined and consistent properties, allowing them to be used reliably in analytical procedures. Examples of reagents include enzymes, antibodies, dyes, metal ions, and organic compounds. In laboratory settings, reagents are often prepared and standardized according to strict protocols to ensure their quality and performance in diagnostic tests and research applications.

I'm sorry for any confusion, but "Schistosomiasis haematobia" is not a recognized medical term. Schistosomiasis is a parasitic disease caused by several species of blood flukes (schistosomes). The two main forms that affect humans are Schistosoma mansoni and Schistosoma haematobium, but the term "haematobia" itself refers to the presence of blood in urine.

So, when we talk about Schistosoma haematobium, it's a specific species of schistosome that causes an infection known as urogenital schistosomiasis, which is characterized by the presence of blood in the urine (haematuria) and other symptoms.

If you have any questions about tropical diseases or parasitic infections, feel free to ask!

Hematuria is a medical term that refers to the presence of blood in urine. It can be visible to the naked eye, which is called gross hematuria, or detected only under a microscope, known as microscopic hematuria. The blood in urine may come from any site along the urinary tract, including the kidneys, ureters, bladder, or urethra. Hematuria can be a symptom of various medical conditions, such as urinary tract infections, kidney stones, kidney disease, or cancer of the urinary tract. It is essential to consult a healthcare professional if you notice blood in your urine to determine the underlying cause and receive appropriate treatment.

Hemoglobinuria is a medical condition characterized by the presence of hemoglobin in the urine. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. Normally, when red blood cells die, they are broken down and their hemoglobin is recycled. However, in certain conditions such as intravascular hemolysis (the destruction of red blood cells inside blood vessels), hemoglobin can be released into the bloodstream and then filtered by the kidneys into the urine.

Hemoglobinuria can be a symptom of various underlying medical conditions, including hemolytic anemias, disseminated intravascular coagulation (DIC), severe infections, snake bites, and exposure to certain toxins or medications. It is important to identify the underlying cause of hemoglobinuria, as treatment will depend on the specific condition.

In some cases, hemoglobinuria can lead to kidney damage due to the toxic effects of free hemoglobin on the renal tubules. This can result in acute or chronic kidney injury, and in severe cases, it may require dialysis or transplantation.

Empyema is a medical condition characterized by the accumulation of pus in a body cavity, most commonly in the pleural space surrounding the lungs. It is usually caused by a bacterial infection that spreads from the lung tissue to the pleural space. The buildup of pus can cause chest pain, cough, fever, and difficulty breathing. Empyema can be a complication of pneumonia or other respiratory infections, and it may require treatment with antibiotics, drainage of the pus, and sometimes surgery.

I believe there may be some confusion in your question. Maleic anhydride is not a medical term, but rather a chemical compound with the formula C2H2O3. It is a white crystalline solid that is used in industrial applications such as the production of polymers and resins.

If you are asking about a medical condition related to exposure or sensitivity to maleic anhydride, I would recommend consulting a medical professional for accurate information. However, in general, inhalation or skin contact with maleic anhydride can cause irritation and respiratory symptoms, and prolonged exposure may lead to more serious health effects. People with sensitivities or allergies to the compound may experience more severe reactions.

Urobilinogen is a colorless or slightly yellowish compound that is formed in the intestines as a byproduct of the breakdown of bilirubin, which is a waste product produced from the breakdown of old red blood cells. Some urobilinogen gets reabsorbed into the bloodstream and is carried to the liver, where it is converted back into bilirubin. The rest is excreted in the stool, giving it its normal brown color.

Abnormally high levels of urobilinogen in the urine can be a sign of certain medical conditions, such as liver disease or hemolytic anemia, which can cause increased breakdown of red blood cells and therefore increased production of bilirubin and urobilinogen. Low levels of urobilinogen in the urine can also be significant, as they may indicate a problem with the liver's ability to reabsorb or metabolize urobilinogen.

It is important to note that urobilinogen testing is not typically used as a standalone diagnostic tool, but rather as one piece of information to be considered in conjunction with other test results and clinical findings.

Schistosoma is a genus of flatworms that cause the disease schistosomiasis, also known as snail fever. These parasitic worms infect freshwater snails and then release a form of the parasite that can penetrate the skin of humans when they come into contact with contaminated water. The larvae mature into adult worms in the human body, living in the blood vessels of the bladder, intestines or other organs, where they lay eggs. These eggs can cause serious damage to internal organs and lead to a range of symptoms including fever, chills, diarrhea, and anemia. Schistosomiasis is a significant public health problem in many tropical and subtropical regions around the world.

"Schistosoma haematobium" is a species of parasitic flatworm, also known as a blood fluke, that causes the disease schistosomiasis (also known as bilharzia). This specific species is the most common cause of urogenital schistosomiasis.

The life cycle of Schistosoma haematobium involves freshwater snails as intermediate hosts. The parasite's eggs are released in the urine of an infected person and hatch in fresh water, releasing miracidia that infect the snail. After several developmental stages, the parasites emerge from the snail as free-swimming cercariae, which then infect the human host by penetrating the skin during contact with infested water.

Once inside the human body, the cercariae transform into schistosomula and migrate to the venous plexus around the bladder, where they mature into adult worms. The female worms lay eggs that can cause inflammation and damage to the urinary tract and, in some cases, other organs. Symptoms of infection can include blood in the urine, frequent urination, and pain during urination. Chronic infection can lead to more serious complications, such as bladder cancer and kidney damage.

Clinical enzyme tests are laboratory tests that measure the amount or activity of certain enzymes in biological samples, such as blood or bodily fluids. These tests are used to help diagnose and monitor various medical conditions, including organ damage, infection, inflammation, and genetic disorders.

Enzymes are proteins that catalyze chemical reactions in the body. Some enzymes are found primarily within specific organs or tissues, so elevated levels of these enzymes in the blood can indicate damage to those organs or tissues. For example, high levels of creatine kinase (CK) may suggest muscle damage, while increased levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) can indicate liver damage.

There are several types of clinical enzyme tests, including:

1. Serum enzyme tests: These measure the level of enzymes in the blood serum, which is the liquid portion of the blood after clotting. Examples include CK, AST, ALT, alkaline phosphatase (ALP), and lactate dehydrogenase (LDH).
2. Urine enzyme tests: These measure the level of enzymes in the urine. An example is N-acetyl-β-D-glucosaminidase (NAG), which can indicate kidney damage.
3. Enzyme immunoassays (EIAs): These use antibodies to detect and quantify specific enzymes or proteins in a sample. They are often used for the diagnosis of infectious diseases, such as HIV or hepatitis.
4. Genetic enzyme tests: These can identify genetic mutations that cause deficiencies in specific enzymes, leading to inherited metabolic disorders like phenylketonuria (PKU) or Gaucher's disease.

It is important to note that the interpretation of clinical enzyme test results should be done by a healthcare professional, taking into account the patient's medical history, symptoms, and other diagnostic tests.

Carboxylic ester hydrolases are a class of enzymes that catalyze the hydrolysis of ester bonds in carboxylic acid esters, producing alcohols and carboxylates. This group includes several subclasses of enzymes such as esterases, lipases, and thioesterases. These enzymes play important roles in various biological processes, including metabolism, detoxification, and signal transduction. They are widely used in industrial applications, such as the production of biodiesel, pharmaceuticals, and food ingredients.

Schistosomiasis, also known as bilharzia or snail fever, is a parasitic infection caused by several species of the trematode flatworm Schistosoma. The infection occurs when people come into contact with freshwater contaminated with the parasite's larvae, which are released by infected freshwater snails.

The larvae penetrate the skin, enter the bloodstream, and mature into adult worms in the blood vessels of the urinary tract or intestines. The female worms lay eggs, which can cause inflammation and scarring in various organs, including the liver, lungs, and brain.

Symptoms of schistosomiasis may include fever, chills, cough, muscle aches, and diarrhea. In chronic cases, the infection can lead to serious complications such as kidney damage, bladder cancer, and seizures. Schistosomiasis is prevalent in tropical and subtropical regions with poor sanitation and lack of access to safe drinking water. It is preventable through improved water supply, sanitation, and snail control measures. Treatment typically involves the use of a medication called praziquantel, which kills the adult worms.

Urine is a physiological excretory product that is primarily composed of water, urea, and various ions (such as sodium, potassium, chloride, and others) that are the byproducts of protein metabolism. It also contains small amounts of other substances like uric acid, creatinine, ammonia, and various organic compounds. Urine is produced by the kidneys through a process called urination or micturition, where it is filtered from the blood and then stored in the bladder until it is excreted from the body through the urethra. The color, volume, and composition of urine can provide important diagnostic information about various medical conditions.

Peritonitis is a medical condition characterized by inflammation of the peritoneum, which is the serous membrane that lines the inner wall of the abdominal cavity and covers the abdominal organs. The peritoneum has an important role in protecting the abdominal organs and providing a smooth surface for them to move against each other.

Peritonitis can occur as a result of bacterial or fungal infection, chemical irritation, or trauma to the abdomen. The most common cause of peritonitis is a rupture or perforation of an organ in the abdominal cavity, such as the appendix, stomach, or intestines, which allows bacteria from the gut to enter the peritoneal cavity.

Symptoms of peritonitis may include abdominal pain and tenderness, fever, nausea and vomiting, loss of appetite, and decreased bowel movements. In severe cases, peritonitis can lead to sepsis, a life-threatening condition characterized by widespread inflammation throughout the body.

Treatment for peritonitis typically involves antibiotics to treat the infection, as well as surgical intervention to repair any damage to the abdominal organs and remove any infected fluid or tissue from the peritoneal cavity. In some cases, a temporary or permanent drain may be placed in the abdomen to help remove excess fluid and promote healing.

Sensitivity and specificity are statistical measures used to describe the performance of a diagnostic test or screening tool in identifying true positive and true negative results.

* Sensitivity refers to the proportion of people who have a particular condition (true positives) who are correctly identified by the test. It is also known as the "true positive rate" or "recall." A highly sensitive test will identify most or all of the people with the condition, but may also produce more false positives.
* Specificity refers to the proportion of people who do not have a particular condition (true negatives) who are correctly identified by the test. It is also known as the "true negative rate." A highly specific test will identify most or all of the people without the condition, but may also produce more false negatives.

In medical testing, both sensitivity and specificity are important considerations when evaluating a diagnostic test. High sensitivity is desirable for screening tests that aim to identify as many cases of a condition as possible, while high specificity is desirable for confirmatory tests that aim to rule out the condition in people who do not have it.

It's worth noting that sensitivity and specificity are often influenced by factors such as the prevalence of the condition in the population being tested, the threshold used to define a positive result, and the reliability and validity of the test itself. Therefore, it's important to consider these factors when interpreting the results of a diagnostic test.

Bacterial infections are caused by the invasion and multiplication of bacteria in or on tissues of the body. These infections can range from mild, like a common cold, to severe, such as pneumonia, meningitis, or sepsis. The symptoms of a bacterial infection depend on the type of bacteria invading the body and the area of the body that is affected.

Bacteria are single-celled microorganisms that can live in many different environments, including in the human body. While some bacteria are beneficial to humans and help with digestion or protect against harmful pathogens, others can cause illness and disease. When bacteria invade the body, they can release toxins and other harmful substances that damage tissues and trigger an immune response.

Bacterial infections can be treated with antibiotics, which work by killing or inhibiting the growth of bacteria. However, it is important to note that misuse or overuse of antibiotics can lead to antibiotic resistance, making treatment more difficult. It is also essential to complete the full course of antibiotics as prescribed, even if symptoms improve, to ensure that all bacteria are eliminated and reduce the risk of recurrence or development of antibiotic resistance.

In a medical context, nitrites are typically referred to as organic compounds that contain a functional group with the formula R-N=O, where R represents an alkyl or aryl group. They are commonly used in medicine as vasodilators, which means they widen and relax blood vessels, improving blood flow and lowering blood pressure.

One example of a nitrite used medically is amyl nitrite, which was previously used to treat angina pectoris, a type of chest pain caused by reduced blood flow to the heart muscle. However, its use has largely been replaced by other medications due to safety concerns and the availability of more effective treatments.

It's worth noting that inorganic nitrites, such as sodium nitrite, are also used in medicine for various purposes, including as a preservative in food and as a medication to treat cyanide poisoning. However, these compounds have different chemical properties and uses than organic nitrites.

Sulfhydryl reagents are chemical compounds that react with sulfhydryl groups (-SH), which are found in certain amino acids such as cysteine. These reagents can be used to modify or inhibit the function of proteins by forming disulfide bonds or adding functional groups to the sulfur atom. Examples of sulfhydryl reagents include N-ethylmaleimide (NEM), p-chloromercuribenzoate (PCMB), and iodoacetamide. These reagents are widely used in biochemistry and molecular biology research to study protein structure and function, as well as in the development of drugs and therapeutic agents.
