rocky mountain spotted fever/edema

A 19-year-old man had multisystem organ failure secondary to Rocky Mountain spotted fever. In addition to renal, cerebral, liver, and gastrointestinal tract involvement he manifested noncardiogenic pulmonary edema and, later, myocardial dysfunction. Aggressive surgical, medical, and monitoring

Despite infrequent respiratory symptoms, histopathologic changes were identified in the lungs of 15 of 16 children dying of Rocky Mountain spotted fever (RMSF). Gross examination demonstrated increased lung weight, edema, congestion, focal hemorrhage, and bronchopneumonia in a few cases. Paraffin

OBJECTIVE To report on the presentation and treatment of a patient with infectious posterior segment uveitis because of infection with Rickettsia rickettsii. METHODS Interventional case report. We conducted a retrospective chart review of a 39-year-old man who presented with a history of acute

A two-year-old female presented with acutely altered mental status following eight days of fever and rash. She had been camping at an Indiana campground 11 days prior to the onset of illness and was evaluated twice for her fever and rash prior to admission. Laboratory evaluation on admission

BACKGROUND Rocky Mountain spotted fever is a life threatening disease caused by Rickettsia rickettsia, characterized by multisystem involvement. METHODS We studied 19 dead children with Rocky Mountain spotted fever. All children who were suspected of having rickettsial infections were defined as

Hepatic tissues from nine patients who had fatal Rocky Mountain spotted fever were examined in sequential sections by brightfield and immunofluorescence microscopy for histologic lesions and for coincidence of these lesions with the distribution of Rickettsia rickettsii. The basic hepatic lesion in

A retrospective study of 35 patients with Rocky Mountain spotted fever was undertaken to determine the frequency of respiratory symptoms, as well as to analyze the types of pulmonary problems encountered to hospital patients. Cough, present in only 33% of patients, led to an incorrect initial

Pulmonary tissue from 10 patients with fatal Rocky Mountain spotted fever was examined by brightfield microscopy for histopathologic lesions and by immunofluorescence for Rickettsia rickettsii. The distribution of rickettsiae and the vasculitis of the pulmonary microcirculation coincided. The lungs

Because myocarditis has been noted frequently as present at necropsy in fatal Rocky Mountain spotted fever (RMSF) and ECG alterations may also accompany the disease, we studied the pathogenesis of myocarditis in RMSF. Increased heart weight in eight of nine cases and increased interstitial volume in

An 86-year-old woman with a history of tick bites in the previous months developed subnormal visual acuity in both eyes, keratic precipitates, anterior chamber and vitreous cells, optic disc edema, retinal hemorrhages, and retinal arteriolar sheathing. She had no fever or skin rash. Three weeks

Dogs were examined ophthalmoscopically to determine the prevalence and type of ocular lesions associated with naturally acquired Rocky Mountain spotted fever (RMSF). In a consecutive series of 11 dogs with serologically confirmed RMSF, 9 had ocular involvement reflecting various degrees of vascular

Rocky Mountain spotted fever occurs during seasonal tick activity. A history of exposure to tick-containing habitats within the 3- to 12-day incubation period is a key epidemiological factor. The signs of fever, headache, myalgia, nausea, vomiting, and anorexia at onset of infection are difficult to

Rickettsiae are arthropod-borne intracellular bacterial pathogens that primarily infect the microvascular endothelium leading to systemic spread of the organisms and the major pathophysiological effect, increased microvascular permeability, and edema in vital organs such as the lung and brain. Much

Mucocutaneous lymph node syndrome is a recently described entity whose principal signs and symptoms include fever, unresponsiveness to antibiotics, congested conjunctivae, reddening of the oral cavity, lips, palms, and soles, exanthem, edema, nonsuppurative cervical adenitis, and desquamation of the

OBJECTIVE To compare neuroimaging findings and clinical features in patients with Rocky Mountain spotted fever and to determine the impact of imaging studies in the treatment of these patients. METHODS We reviewed the brain CT scans (n = 44), MR images (n = 6), or both (n = 4), and one MR spinal
