1/34. 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) |

3/34. 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) |
4/34. 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 = 434.35988342509keywords = brucellosis, fever (Clic here for more details about this article) |
5/34. 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 = 434.35988342509keywords = brucellosis, fever (Clic here for more details about this article) |
6/34. 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) |
7/34. Acute cholecystitis caused by brucella melitensis: case report and review.brucellosis is a common zoonosis in many parts of the world. Human brucellosis is a multisystemic disease with a wide range of clinical symptoms. Biliary involvement in the form of acute cholecystitis is a very rare manifestation of brucellosis. Here we report the case of a 34-year-old male with acute cholecystitis caused by brucella melitensis and review seven other cases. We conclude that brucella may have a focal effect on the gallbladder, in the form of acute cholecystitis.- - - - - - - - - - ranking = 173.34395337004keywords = brucellosis (Clic here for more details about this article) |
8/34. 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) |
9/34. Human brucellosis.BACKGROUND: Human brucellosis has a serious medical impact worldwide, and its eradication poses major difficulties. Although human brucellosis is relatively rare in the united states (approximately 100 cases per year), there is concern that this disease is largely underdiagnosed and underreported. Additionally, immigrants from endemic areas are arriving to this country, and Brucella species are considered to be biologic agents for terrorism. Human brucellosis affects all age-groups, and family physicians are not well versed in recognizing and treating this potentially life-threatening condition. methods: A literature review from 1975 to 2001 was performed using the key words "human brucellosis," "zoonosis," and "bioterrorism." RESULTS AND CONCLUSIONS: Appropriate antimicrobial therapy and duration of treatment of human brucellosis will reduce morbidity, prevent complications, and diminish relapses. Because of the nonspecific symptoms and rarity of human brucellosis in the united states, family physicians must acquire a detailed dietary and occupational history to diagnose the disease promptly. family physicians must assume a responsible role in reporting this disease, as well as be aware of persons at high-risk for this disease and the potential sources of infection.- - - - - - - - - - ranking = 866.71976685018keywords = brucellosis (Clic here for more details about this article) |
10/34. Laboratory outbreak of q fever.An outbreak of q fever in a university department where sheep placentas were being used for research is described.
