1/33. Mayaro virus disease: an emerging mosquito-borne zoonosis in tropical south america.This report describes the clinical, laboratory, and epidemiological findings on 27 cases of Mayaro virus (MV) disease, an emerging mosquito-borne viral illness that is endemic in rural areas of tropical south america. MV disease is a nonfatal, dengue-like illness characterized by fever, chills, headache, eye pain, generalized myalgia, arthralgia, diarrhea, vomiting, and rash of 3-5 days' duration. Severe joint pain is a prominent feature of this illness; the arthralgia sometimes persists for months and can be quite incapacitating. Cases of two visitors from the united states, who developed MV disease during visits to eastern peru, are reported. MV disease and dengue are difficult to differentiate clinically.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |

3/33. Visceral manifestation of cat scratch disease in children. A consequence of altered immunological state?A 12-year-old girl with a 2-month history of fever and abdominal pain was admitted to our hospital. Ultrasound and CT scans of the abdomen showed multiple hypoechoic lesions of liver and spleen. Screening for zoonosis revealed high positive titers to bartonella henselae. T-cell deficiency was demonstrated and remained almost unchanged during a follow-up of 11 months. A review of the literature shows that disseminated visceral affection is a rare presentation of cat scratch disease (CSD) in childhood and adolescence. Further immunological investigations are needed in more patients with CSD to confirm whether an altered immunological state may be responsible for the atypical visceral manifestation of CSD.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
4/33. Cutaneous manifestations in brucellosis: case report and review of the literature.brucellosis is a classical common zoonotic disease of worldwide distribution. skin complications are infrequent and affect less than 5% of patients with brucellosis, although they may occasionally occur during the clinical course of the disease. Here, we report a case of a shepherd presenting with fever and a diffuse maculopapular rash due to brucella melitensis infection, and we provide a review of the relevant literature.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
5/33. brucellosis in laboratory workers at a Saudi Arabian hospital.BACKGROUND: saudi arabia is hyperendemic for brucellosis, with more than 8000 cases reported each year to public health authorities. During 1998, brucellosis ranked as the No. 1 reportable communicable disease (22.5%) in Saudi Arabian National Guard communities. King Fahad Hospital is the major referral center for National Guard personnel in the nation's central region.methods And Results: From 1991 to 2000, brucellosis developed in 7 expatriate hospital employees. Six employees were bacteriology technologists, and one was a pathologist. Each had a clinical syndrome compatible with brucellosis (headache, fever, rigors, sweats, and myalgias) plus elevated Brucella sp serum agglutinin titers > or = 1:1280; one patient also had positive blood cultures. All patients responded to anti-Brucella therapy. Two patients had relapses, and complications occurred in four patients (septic endophlebitis of the leg, infected prosthesis, epididymoorchitis, and lumbar spondylitis). In all these employees except the pathologist, the infection was associated with processing Brucella sp cultures. CONCLUSION: Despite the enforcement of stringent infection control measures including the use of a class II biosafety hood in the laboratory, the problem of nosocomial brucellosis persists because of the large number of infected specimens handled by the laboratory (17,500 specimens per year). Ultimately, risk reduction depends on efforts to reduce disease endemicity in the country. In the meantime, conversion of the laboratory to biosafety level 3 is under way.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
6/33. Parinaud's oculoglandular syndrome attributable to an encounter with a wild rabbit.PURPOSE: To describe the clinical and histopathologic findings in a patient with Parinaud's oculoglandular syndrome attributable to francisella tularensis obtained from an encounter with a wild baby rabbit. methods: In an 18-year-old man, the clinical course, laboratory findings, and histopathologic findings are described. RESULTS: Parinaud's oculoglandular syndrome should be considered in the differential diagnosis of a patient presenting with unilateral granulomatous conjunctivitis, painful preauricular, and submandibular lymphadenopathy combined with systemic symptoms of general malaise and fever. CONCLUSION: tularemia is one etiology of Parinaud's oculoglandular syndrome. It is caused by francisella tularensis and is usually transmitted to humans via infected animal blood or through an insect bite, most often a tick. For treatment, intramuscular streptomycin is the drug of choice.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
7/33. west nile fever in israel 1999-2000: from geese to humans.west nile virus (WNV) caused disease outbreaks in israel in the 1950s and the late 1970s. In 1998 an outbreak of WNV in goose farms and evidence of infection in dead migratory birds were reported. Consequently, human diagnostic services for WNV were resumed, including virus isolation, serology, and RT-PCR. risk factors for infection were assessed by a serological survey in 1999, which revealed a seroprevalence of (a) 86% in people who had close contact with sick geese, (b) 28% in people in areas along bird migration routes, and (c) 27% in the general population. Following two fatal cases in Tel Aviv in September 1999 and one encephalitis case in the southern Eilot region, a regional serological survey was initiated there. The survey revealed two more WNV-associated acute encephalitis cases, an IgG seroprevalence of 51%, and an IgM seroprevalence of 22%. In the summer of 2000, acute cases of WN disease were identified in the central and northern parts of israel, involving 439 people. The outbreak started in mid-August, peaked in September, and declined in October, with 29 fatal cases, primarily in the elderly. During the outbreak, diagnosis was based on IgM detection. Four virus isolates were subsequently obtained from preseroconverted frozen sera. Sequence and phylogenetic analysis of 1662 bases covering the PreM, M, and part of the E genes revealed two lineages. One lineage was closely related to a 1999 Israeli bird (gull) isolate and to a 1999 new york bird (flamingo) isolate, and the other lineage was closely related to a 1997 Romanian mosquito isolate and to a 1999 Russian human brain isolate.- - - - - - - - - - ranking = 4keywords = fever (Clic here for more details about this article) |
8/33. Laboratory outbreak of q fever.An outbreak of q fever in a university department where sheep placentas were being used for research is described. Of six persons exposed to the sheep, four had positive titers with only one person developing an acute febrile illness and liver disease. This report illustrates the value of the family physician obtaining an occupational history and conducting an outbreak investigation.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
9/33. Report of three children with leptospirosis in rural area of the east of turkey.leptospirosis is a systemic infection usually producing fever with hepatorenal involvement, meningoencephalitis, and hemorrhage. In this article, we present three children between 10 and 13 years of age with leptospirosis. The purpose of this paper is to emphasize that leptospirosis is a problem in our country with farmers/cattle and that leptospirosis should be considered in certain ill children. The main symptoms were headache, fever, fatigue, abdominal pain and unconsciousness. Two patients had hepatic and renal involvement. The other had hepatic, pulmonary and probably pericardial involvement. In all children spirochetes were demonstrated in blood and urine smears by dark-field microscopy and they were also isolated from urine and blood cultures by using Flecher medium. All patients were treated with penicillin; however, one subsequently required additional antibiotics due to klebsiella pneumoniae septicemia. While one patient was discharged in a good health, the others were taken to their home by parents without completing treatment. In conclusion, we would like to emphasize that leptospirosis is still a public health problem in our region (Eastern turkey) in where the majority of population are farmers and raise domestic animals such as cattle in rural areas. Additionally, leptospirosis should be considered in children admitted with headache, unconsciousness, fever and abdominal pain.- - - - - - - - - - ranking = 3keywords = fever (Clic here for more details about this article) |
10/33. Implications of presumptive fatal rocky mountain spotted fever in two dogs and their owner.A dog was examined because of petechiation, an inability to stand, pale mucous membranes, a possible seizure, and thrombocytopenia. Tick-borne illness was suspected, but despite treatment, the dog died. Eight days later, a second dog owned by the same individual also died. The dog was not examined by a veterinarian, but rocky mountain spotted fever (RMSF) was suspected on the basis of clinical signs. Two weeks after the second dog died, the owner was examined because of severe headache, fever, nausea, vomiting, decreased appetite, lethargy, and a fine rash on the body, face, and trunk. Despite intensive treatment for possible RMSF, the owner died. Although results of an assay for antibodies to rickettsia rickettsii were negative, results of polymerase chain reaction assays of liver, spleen, and kidney samples collected at autopsy were positive for spotted fever group Rickettsia spp. These cases illustrate how dogs may serve as sentinels for RMSF in humans and point out the need for better communication between physicians and veterinarians when cases of potentially zoonotic diseases are seen.- - - - - - - - - - ranking = 7keywords = fever (Clic here for more details about this article) |
