Rate of Spontaneous Resolution of Congenital Nasolacrimal Duct Obstruction Prior to Scheduled Probing in Children Older Than 1 Year.

The authors conducted a 10-year retrospective review of all patients within one physician's practice to determine the frequency of spontaneous resolution of congenital nasolacrimal duct obstruction in children older than 1 year during the interval between scheduling and date of probing. This review found 4.4% of eyes resolved within an average interval period of 39 days.

Degradation and sorption of imidacloprid in dissimilar surface and subsurface soils.

Degradation and sorption/desorption are important processes affecting the leaching of pesticides through soil. This research characterized the degradation and sorption of imidacloprid (1-[(6-chloro-3-pyridinyl)-methyl]-N-nitro-2-imidazolidinimine) in Drummer (silty clay loam) and Exeter (sandy loam) surface soils and their corresponding subsurface soils using sequential extraction methods over 400 days. By the end of the incubation, approximately 55% of imidacloprid applied at a rate of 1.

Biodegradation of imidacloprid by an isolated soil microorganism.

Imidacloprid (1-[(6-chloro-3-pyridinyl)-methyl]-N-nitro-2-imidazolidinimine), a chloronicotinyl insecticide used to control biting and sucking insects, is very persistent in the soil with a half-life often greater than 100 days. Although a few soil metabolites have been reported in the literature, there are no reports of imidacloprid-degrading soil microorganisms. Our objectives were to discover, isolate, and characterize microorganisms capable of degrading imidacloprid in soil.

Bias of Tedlar bags in the measurement of agricultural odorants.

Odor regulations typically specify the use of dynamic dilution olfactometery (DDO) as a method to quantify odor emissions, and Tedlar bags are the preferred holding container for grab samples. This study was conducted to determine if Tedlar bags affect the integrity of sampled air from animal operations. Air samples were collected simultaneously in both Tedlar bags and Tenax thermal desorption tubes.

Sorption-desorption of two "aged" sulfonylaminocarbonyltriazolinone herbicide metabolites in soil.

Aging (herbicide-soil contact time) has been shown to significantly affect the sorption-desorption characteristics of many herbicides, which in turn can affect the availability of the herbicide for transport, plant uptake, and microbial degradation. In contrast, very little work in this area has been done on herbicide metabolites in soil. The objective of this study was to characterize the sorption-desorption of sulfonylaminocarbonyltriazolinone herbicide metabolites incubated in soils at different soil moisture potentials.

Sorption-desorption of "aged" sulfonylaminocarbonyltriazolinone herbicides in soil.

Sorption-desorption interactions of pesticides with soil determine the availability of pesticides in soil for transport, plant uptake, and microbial degradation. These interactions are affected by the physical and chemical properties of the pesticide and soil, and for some pesticides, their residence time in the soil. The objective of this study was to characterize sorption-desorption of two sulfonylaminocarbonyltriazolinone herbicides incubated in soils at different soil moisture potentials.

Degradation of atrazine, metolachlor, and pendimethalin in pesticide-contaminated soils: effects of aged residues on soil respiration and plant survival.

This study was conducted to determine the effects of pesticide mixtures on degradation patterns of parent compounds as well as effects on soil microbial respiration. Bioavailability of residues to sensitive plant species was also determined. Soil for this study was obtained from a pesticide-contaminated area within an agrochemical dealer site.

Screening for Chlamydia trachomatis infection in college women with a polymerase chain reaction assay.

This study sought to determine factors associated with chlamydial infection in a low-prevalence college health setting and to determine the testing characteristics of a polymerase chain reaction (PCR) assay for chlamydial infection (AMPLICOR chlamydia test; Roche Diagnostic Systems, Indianapolis) in this population. Young women (n = 1,149) at a university student health clinic underwent testing for cervical chlamydial infection by PCR assay and culture; the characteristics of women with and without chlamydial infection were compared. Chlamydial infection was diagnosed for 26 students (2.

Enhanced degradation of deethylatrazine in an atrazine-history soil of Iowa.

The degradation of deethylatrazine (DEA), a major metabolite of atrazine, was studied by using radiotracers in soils with two different atrazine histories. DEA degradation was enhanced in soils which had received long-term exposure to atrazine (atrazine-history soil) compared with soils that had not received long-term atrazine exposure (no-history soil). After 60 days of incubation, mineralization of DEA to 14CO2 in the atrazine-history surface soil was twice that in the no-history surface soils, with 34% and 17% of the applied 14C-DEA as CO2, respectively.

Comparison of direct specimen testing utilizing TestPack strep A with testing of specimens following a two-hour broth enrichment.

In a previous study, we demonstrated that a 2-h enrichment of throat swabs in broth followed by a direct fluorescent antibody test was significantly more sensitive than the Abbott TestPack Strep A for the detection of group-A streptococci. In this study, in an effort to simplify the technique, we utilized broth enrichment with an enzyme immunoassay detection method. A total of 1017 pharyngeal specimens were tested with TestPack Strep A (DTP), culture on a selective streptococcal agar, and a 2-h broth enrichment in Todd-Hewitt broth (THB) followed by TestPack Strep A (ETP).

Prevention of infection in critically ill patients by selective decontamination of the digestive tract.

Objective: To determine whether selective decontamination of the digestive tract using oral and nonabsorbable antimicrobial agents and parenteral cefotaxime prevents infection in critically ill patients.

Design: Randomized, controlled trial without blinding.

Setting: Surgical trauma and medical intensive care units in a tertiary referral hospital.

Comparison of three methods for detection of group A streptococci in throat swabs.

Group A streptococci are generally detected in throat swabs by (i) rapid antigen tests, (ii) conventional culture, or (iii) combinations of both. Direct fluorescent-antibody testing of a 2-h enrichment broth (FA/EN) was an accepted method for same-day results before the advent of rapid antigen tests. We compared FA/EN in Todd-Hewitt Broth (THB) with conventional culture and a rapid antigen test, TestPack Strep A (TPS).

Thirty cases of nontyphoidal Salmonella bacteriuria were identified by review of cultures performed at the Mayo Clinic (Minn.) from 1985 to 1989 and at the Federal Public Health Laboratory Innsbruck (Austria) from 1979 to 1989. All patients had symptoms of an acute urinary tract infection (UTI).

Campylobacter fetus subspecies fetus infection.

During a six-year period five patients with Campylobacter fetus subspecies fetus infections were seen at the Mayo Clinic in Rochester, Minnesota. Bacteremia was observed in two patients, one presenting with aortic valve endocarditis and the other with abdominal atherosclerotic aortic aneurysm. C.

Prospective evaluation of the risk of bacteremia associated with transesophageal echocardiography.

Background: Transient bacteremia may lead to endocarditis in patients with significant valvular lesions.

Methods And Results: Because transesophageal echocardiography selects a patient population with a high prevalence of valvular lesions, we prospectively evaluated the risk of transient bacteremia associated with transesophageal echocardiography in 49 patients. Blood cultures were obtained immediately before transesophageal echocardiography and at 5, 10, and 20 minutes after the start of the procedure.

Cutaneous botryomycosis.

We report four cases of cutaneous botryomycosis. The predisposing factors included alcoholism, diabetes, and trauma. Clinically, the patients had nodules, suppurative plaques, or ulcers.

Campylobacter bacteremia: clinical experience with three different blood culture systems at Mayo Clinic 1984-1990.

Application of quadFERM+ for the identification of fastidious gram-positive and gram-negative bacilli.

The 2-hr quadFERM+ kit (qF) (Analytab Products, Plainview, NY) was compared with conventional tube tests for the identification of the HACEK bacteria (Haemophilus aphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, Kingella kingae), other Haemophilus and Kingella spp., Capnocytophaga, Corynbacterium, and Moraxella spp. Test results were identical for 296 comparisons with 74 isolates (74%).

Evaluation of calcofluor white stain for detection of Pneumocystis carinii.

A rapid calcofluor white (CFW) stain for detecting Pneumocystis carinii was evaluated prospectively. Eighty-nine bronchoalveolar lavage (BAL) specimens, 21 open-lung biopsy (OLB) tissues, 2 induced sputums, 1 expectorated sputum, 2 tracheal secretions, and 1 bronchial secretion from 102 patients were examined for P. carinii cysts by both the CFW stain and a modified methenamine silver (MS) stain.

Results of a 6-month survey of stool cultures for Escherichia coli O157:H7.

Escherichia coli O157:H7 is a recently recognized enteric pathogen that causes acute hemorrhagic colitis. Although the infection is usually self-limited, it may be complicated by hemolytic uremic syndrome and thrombotic thrombocytopenic purpura. At our institution, stool specimens are now routinely cultured for this organism.
