Clinical pathogenesis of typhoid fever.

Human infections with Salmonella enterica results in two major groups of diseases: gastroenteritis and typhoid fever. Clinical observations suggest that gastroenteritis, caused by non-typhoidal Salmonella serovars, is characterized by a massive neutrophil influx, which keeps the infection localized to the intestinal mucosa. In contrast, the absence of neutrophilic intestinal infiltrates in the acute phase of typhoid fever suggests a propensity for typhoidal Salmonella serovars (S. Typhi, S. Paratyphi A, S. Paratyphi B and S. Paratyphi C) to evade aspects of the innate immune response and cause…

Sandfly fever Sicilian virus, Algeria.

To determine whether sandfly fever Sicilian virus (SFSV) is present in Algeria, we tested sandflies for phlebovirus RNA. A sequence closely related to that of SFSV was detected in a Phlebotomus ariasi sandfly. Of 60 human serum samples, 3 contained immunoglobulin G against SFSV. These data suggest SFSV is present in Algeria.

Pediatric myth: fever and petechiae.

A child presenting with petechiae and fever is assumed to have meningococcemia or another form of bacterial sepsis and therefore to require antibiotics, blood cultures, cerebrospinal fluid analysis and hospital admission. A review of the literature challenges this statement and suggests that a child presenting with purpura (or petechiae), an ill appearance and delayed capillary refill time or hypotension should be admitted and treated for meningococcal disease without delay. Conversely, a child with a petechial rash, which is confined to the distribution of the superior vena cava, is unlikely …

[Myalgia in familial Mediterranean fever].

INTRODUCTION: Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent attacks of fever and painful episodes of sterile peritonitis, pleuritis and arthritis. Among rare symptoms of the disease, muscular manifestations, first described in 1945, sometimes as one of the main clinical manifestations or as its sole feature should be recognized. We present a patient with FMF in whom severe myalgia were predominant. CASE REPORT: An 18 year-old Tunisian boy treated with corticosteroids for an "inflammatory myopathy" in another institution was admitted for abdomi…

Vaccines for preventing typhoid fever.

BACKGROUND: Two typhoid vaccines are commercially available, Ty21a (oral) and Vi polysaccharide (parenteral), but neither is used routinely. Other vaccines, such as a new modified, conjugated Vi vaccine called Vi-rEPA, are in development. OBJECTIVES: To evaluate vaccines for preventing typhoid fever. SEARCH STRATEGY: In December 2006, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (The Cochrane Library 2006, Issue 3), MEDLINE, EMBASE, LILACS, and mRCT. We also searched relevant conference proceedings up to 2004 and scanned the reference lists of all included…

Enteric fever: an Israeli perspective.

Typhoid fever is no longer endemic to most developed countries, including Israel. When encountered, it usually occurs in travelers returning from endemic countries. Worldwide, the disease is far from being eradicated. It is still highly prevalent in some popular travel destinations such as India. With the continued increase in Israelis traveling to (and in migrant workers arriving from) endemic regions, physicians in Israel should be well acquainted with the disease. Unfortunately, with the limited efficacy of the current typhoid vaccinations and the increase in multidrug-resistant strains, ca…

Neurological complications in Chikungunya fever.

OBJECTIVE: The present prospective study was undertaken to study the clinical manifestations and mainly neurological complication of an acut … vement and any permanent damage or death. RESULTS: Apart from typical clinical triad of high grade fever, arthralgia and rash of chikungunya infection we have observed a spectrum of neurological abnormalities in terms of altered mental functions, seizures, focal neurological deficit with abnormal CT scan of head and altered CSF biochemistry. Permanent …

Лечение аргентинской геморрагической лихорадки.

Аргентинская геморрагическая лихорадка (AHF) — болезнь, вызванная грызуном, вызванная аренавирусом Юнином, эндемичным у влажных пампасов Аргентины. С момента своего появления в 1950-х годах АХФ страдала значительной заболеваемостью, причем коэффициент заболеваемости без лечения составлял от 15 до 30 процентов. Использование живой вакцины с ослабленными характеристиками заметно сократило распространенность АХФ. Нынешняя специфическая терапия предполагает переливание иммунной плазмы в определенных дозах нейтрализации антител во время продромальной фазы болезни. Однако в связи с нынешними труднос

Argentine hemorrhagic fever (AHF) is a rodent-borne illness caused by the arenavirus Junin that is endemic to the humid pampas of Argentina. AHF has had significant morbidity since its emergence in the 1950s, with a case-fatality rate of the illness without treatment between 15% and 30%. The use of a live attenuated vaccine has markedly reduced the incidence…

Rocky Mountain spotted fever, Colombia.

We investigated 2 fatal cases of Rocky Mountain spotted fever that occurred in 2003 and 2004 near the same locality in Colombia where the disease was first reported in the 1930s. A retrospective serosurvey of febrile patients showed that > 21% of the serum samples had antibodies aaainst spotted fever group rickettsiae.

Rocky Mountain spotted fever, Panama.

We describe a fatal pediatric case of Rocky Mountain spotted fever in Panama, the first, to our knowledge, since the 1950s. Diagnosis was established by immunohistochemistry, PCR, and isolation of Rickettsia rickettsii from postmortem tissues. Molecular typing demonstrated strong relatedness of the isolate to strains of R. rickettsii from Central and South America.

Boutonneuse fever and climate variability.

Researchers have long appreciated the role of climate in vector-borne diseases, including the resurgence of boutonneuse fever (BF). Portugal usually is classified as having temperate Mediterranean climate. In this new century, in analyzing the data from the Meteorology Institute, this pattern has changed and an accentuated variability in climate is being observed. BF (febre escaro nodular) is endemic and high season is from late spring and summer. The brown dog tick Rhipicephalus sanguineus. is the vector and reservoir of Rickettsia conorii complex strains: R. conorii Malish and Israeli spotte…
