Strong Suspicion (strong + suspicion)
Selected AbstractsIncidence, spectrum and antibiotic sensitivity pattern of bacterial infections among patients with acute pancreatitisJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 9 2001Pramod Kumar Garg Abstract Background and Aim: Secondary infection of pancreatic necrotic tissue and peripancreatic fluid is a serious complication of acute pancreatitis resulting in significant morbidity and mortality. The aim of this study was to find out the spectrum of bacterial infections, and their antibiotic sensitivity pattern in patients with acute pancreatitis. Methods: All consecutive patients with acute pancreatitis were studied prospectively. Detailed investigations were carried out to identify bacterial infections and their antibiotic sensitivities in patients with suspected infection. These investigations included cultures of various body fluids, throat swabs, indwelling cannula and catheter tips. Pancreatic tissue was obtained by using needle aspiration or at surgery for Gram's stain, culture and sensitivity. All cultures were repeated until the presence of infection was confirmed or excluded. Results: A total of 169 patients with acute pancreatitis were studied during the period between January 1997 and June 2000 (mean age 41.3 years; 116 males and 53 females). Of the 169 patients, 63 had infections at various sites. A total of 80 cultures were positive, and 12 different bacterial isolates were cultured from samples taken from these 63 patients. Polymicrobial infection was seen in 32% of patients. Twenty-four patients had a confirmed pancreatic infection. Blood cultures had a growth of organisms in 19 patients, with evidence of ongoing or worsening pancreatitis, thus raising a strong suspicion of infected necrosis in them. The commonest organisms were Escherichia coli from 20 cultures and Pseudomonas aeruginosa from 18 cultures. The antibiotic sensitivity pattern showed that most bacteria were sensitive to third generation cephalosporins and quinolones; notably among them were cefotaxime, ceftazidime, and ciprofloxacin. Conclusion: Bacterial infections were seen in 37% of patients with acute pancreatitis. The commonest organisms were Pseudomonas aeruginosa and Escherichia coli. Most bacterial isolates were sensitive to third generation cephalosporins and quinolones. [source] Lyme borreliosis in Sweden , diagnostic performance of five commercial Borrelia serology kits using sera from well-defined patient groupsAPMIS, Issue 1 2004Brief report Five commercial Borrelia serology kits available in Sweden were evaluated and compared for their diagnostic performance in sera from clinically well-characterized patient groups. With the clinically defined groups as the gold standard, i.e. without knowledge of antibody status in serum and cerebrospinal fluid, the diagnostic performance of the kits was compared and important differences in diagnostic usefulness were found. The kits from Abbot and DAKO, that often predict clinically relevant Borrelia infection and do not detect antibodies in sera from patients without strong suspicion of Borrelia infection, were considered the most useful in the population studied. This kind of validation study is an important part of good laboratory practice and should be performed by laboratories serving patient populations with varying endemicity of Borrelia. [source] Investigation for immunodeficiency in patients with recurrent ENT infectionsCLINICAL OTOLARYNGOLOGY, Issue 3 2001T.R. Cooney Patients suffering with primary immunodeficiency frequently present to ear, nose, and throat (ENT) clinics, but the diagnosis is rarely made at this time. Early diagnosis of these patients would help to prevent morbidity and even mortality. Normal results from a simple panel of blood tests will exclude the commonest immune deficiencies. An abnormal result from these tests, or a strong suspicion despite normal initial testing, should prompt discussion with an immunologist. [source] Survey of the vectorial competence of ticks in an endemic area of spotted fever group rickettsioses in Fukui Prefecture, JapanMICROBIOLOGY AND IMMUNOLOGY, Issue 6 2008Fubito Ishiguro ABSTRACT The prevalence of SFGR in ixodid ticks in the Mt. Arashima-dake area in the northern part of Fukui Prefecture was surveyed, because of strong suspicions that the first case identified in this Prefecture had become infected with R. helvetica in this region. The ticks identified consisted of three genera and six species; I.ovatus, I. persulcatus, I. monospinosus, H. flava, H. japonica and D. taiwanensis. Of all 222 ticks collected, only I. monospinosus ticks (8 of 32 examined) were positive for SFGR isolates, which were genetically identified as R. helvetica. Ticks (157 of all 222) positive for SFGR-DNA fragments consisted of I. monospinosus (14 of 32), I. persulcatus (11 of 55), I. ovatus (3 of 38), H. flava (5 of 21) and H. japonica (2 of 9). Of these, thirteen I. monospinosus, eight I. persulcatus, three I. ovatus, two H. flava and one H. japonica were identified by nucleotide sequences as positive for R. helvetica. DNA fragments from three H. flava and one H. japonica showed greater homology to R. japonica than to R. helvetica or R. asiatica. The present results indicate that it is most likely that the vector tick of R. helvetica infection in Fukui Prefecture is I. monospinosus. [source] |
