Hantavirus infections are now recognized to be a global problem. The hantaviruses include several genotypic variants of the virus with different distributions in varying geographical regions. The virus genotypes seem to segregate in association with certain manifestations specific for each syndrome. They primarily include HFRS, HCPS, febrile illness with or without mild involvement of renal diseases. In the course of our study on hantavirus etiology of febrile illnesses, we recovered a hantavirus strain identified by nPCR...

Hemorragic dengue fever is a prevalent infection in many countries around the world. Myocarditis is a severe manifestation of dengue virus infection. With prompt intervention and an early diagnosis, the outcome of this condition can be improve. We report a adult patient with complicated dengue, myocarditis, cardiac and respiratory insufficiency with acute renal injury.

Bioterrorists seek to use highly virulent pathogens to cause social and economic disruption. Historical agents such as anthrax, Yersinia pestis and botulinum toxin can easily be produced, whereas others such as hemorragic fever virus require much more sophisticated infrastructure and government-scale resources. In the near future, with the spread of new biotechnologies, bioterrorists may produce new transgenic pathogens. Epidemiological surveillance and diagnostic capacities should thus be more reactive. Real-time epidemiological surveillance together with a network of high-security laboratories would enable us to cope effectively with new infectious diseases that emerge naturally or through human manipulation...

Among eleven convalescent patients of Argentine hemorragic fever an electro-ballistocardiographic study was effected which led to the following conclusions: a) In 2 over 11 studied cases, electro-ballistocardiographic modifications of probable myocardial injury could be detected. b) The greatest percentage of the modifications was interpreted as normal variants of the electrocardiogram.

Programmed cell death (PCD) is a fundamental process regulating immune homeostasis. During acute viral infections PCD of lymphocytes by apoptosis is necessary for removing the excess of activated antigen-reactive T cells and down-regulation of the immune response. On the other hand, apoptosis is the key mechanism of elimination of viral-infected cells. At the present time there is virtually no data on mechanisms of immune regulation during human hantavirus infections. In this study we examined the dynamic of PBL Fas and FasL expression, the first-step dead caspase-8, -2, -9 and effector caspase-3, -7 and -10 activity in freshly isolated PBL lysates, and anti-CD3-induced PBL mitogenic response and apoptosis in patients with Puumala virus (PUUV) associated hemorrhagic fever with the renal syndrome (HFRS)...

The present study, conducted from March 1998 to July 2000, determined the etiology of acute diarrhea in 253 young children and infants from Cartagena and Sincelejo, Colombia. In 253 stool samples, the following enteric pathogens were recovered: rotavirus type A (36.6%) as the major agent, Salmonella spp (9.0%), Shigella spp (8.0%), enteric pathogenic Escherichia coli (6.0%), enteric hemorragic Esc. coli (2.8%), Providencia alcalifaciens (2.8%), Aeromonas hydrophila (2.0%), Yersinia enterocolitica (0.8%), Entamoeba hystolitica (10%), Giardia lamblia (4%), Endolimax nana (3...

BACKGROUND: Gemcitabine (G) and vinorelbine (V) have favorable safety profile and antitumor activity in metastatic breast cancer. To exploit their different mechanism of action and lack of overlapping toxicity, we performed a phase I and II study of G and V in combination. PATIENTS AND METHODS: Fifty-three patients with metastatic breast cancer were treated. In the dose-finding phase, seven cohorts of patients (22 women) received increasing doses to determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) of the combination...

In this monograph are analysed the principal infections transmitted by ticks and particularly those interesting Europe and North America. Besides the main species of these arthropods are described in consideration of their characteristics and geographic diffusion. In particular the infections caused by Borrelia genus and tick born encephalitis virus are treated more exhaustively in consideration of their potential severity and because the diagnosis of these infections is sometimes difficult. However also the main rickettsial infections transmitted by ticks are reported together the hemorragic fevers transmitted by such arthropods...

AIM: Meckel s diverticulum is the most common congenital abnormality of the small bowel. It may be silent or symptomatic when complicated by hemorrage, intestinal occlusion, diverticulitis and umbilical fistulas. Radiologic diagnosis is often difficult because abdominal plain radiography and ultrasound are not sufficiently specific; CT is most accurate in differential diagnosis. MATERIAL AND METHODS. 11 patients (age 5-69 ys) were studied. Clinical symptoms included acute abdomen (4 pts), intestinal occlusion (3 pts), abdominal pain (4 pts), fever (5 pts)...

We report the case of a 40-year-old-man who developed febrile cytolysis as the presenting sign of hemorragic fever with renal syndrome (HFRS). On admission, he had fever (40 degrees C) and epigastric pain. The AST level was at 2N, the ALT at 3N. There was a thrombocytopenia (61 000/mm(3)) without anemia or hyperleukocytosis. Three days after admission, the platelet count decreased to 40 000/mm(3), serum urea and creatinine increased from normal rate to 10.8mmol/l, 204.0 micromol/l, respectively. The HIV, HBV, HCV, leptospirosis antibodies were negative...

Dengue is a human disease of viral etiology which may be fatal in its hemorragic form. It is widely spread in the tropical areas of the different continents and has been dramatically expanding over the past 30 years. Although an immunological disorder is thought to be involved in dengue physiological symptoms, the pathogenesis of dengue hemorragic fever has not yet been elucidated. Whether the immune response is deleterious or beneficial to the host remains a matter of debate. Other factors, related to virus replication in specific host cells, could also contribute to the severity of the disease...

Brucella endocarditis was diagnosed in a 21-year-old itinerant farm worker hospitalized for acute pulmonary edema. History taking revealed cough, fever and sweating one month earlier which had been treated with antibiotics. At admission, echography showed lesions on the aortic valve and hemocultures identified Brucella meltensis. On day 7 of specific treatment with doxycycline (200 mg/day) and rifamycine (1200 mg/day), and despite digitalics and diuretics, left ventricular failure rapidly worsened, leading to cardiac arrest and death before emergency surgery could be performed...

In Azerbaidjan, a rural province in the North-West of Iran, an hemorragic fever has been described, with a seasonal occurrence, mainly in July. it is characterized with the penia and thrombocytopenia. Its identification with the hemorragic fever of Crimea-Congo has been ruled out on clinical and biological arguments. In a new survey, fever appeared to be generally moderate or absent and the clinical aspect is that of a thrombocytopenic purpura. The role of a virus transmitted by tick, and a toxic etiology have been both suspected but not proved...

Ticks have been collected on cattle skins for seven consecutive years in Bangui, Berberati, Bangassou and Bouar. 150 strains of arboviruses have been isolated from the four following species: Amblyomma variegatum: Dugbe, Jos, Thogoto, Crimean-Congo Hemorragic Fever (CCHF), Yellow Fever, Bhanja and Pétévo; Boophilus annulatus: Dugbe, Jos and Thogoto; B. decoloratus: Dugbe, Jos, Thogoto and CCHF; Hyalomma nitidum: CCHF. Dugbe (112 isolated strains), Jos (19 isolates) and Thogoto (11 isolates) viruses represent more than 95% of all the strains...

Reviewing 67 cases of human adult shigellosis observed in Madagascar, the authors emphasize some epidemiologic and clinic features : high frequency during rainy season, usual dysenteriform aspect or diarrhoeas with fever, hemorragic forms, severity according to anterior state of colon and rectum, severity if cases associated with amoebiasis or schistosomiasis (Schistosoma mansoni).

Eighty four cases of meningococcal infections are reviewed. Fifty seven cases presented themselfs as meningococcal meningitis, twelve cases as sepsis with moderate hypotension and 15 cases were sepsis with septic shock. A brief course of the disease, shock, echymosis, absence of meningeal signs, leucopenia and intravascular coagulation were findings more frequent in the group of patients with hiperacute sepsis, whereas other signs as fever, headaches, vomiting and petechiae were present with equal frequency in the three groups...
