10 Possible Causes for Leukocytes Decreased, Patient Appears Acutely Ill, Retroorbital Pain

  • Influenza

    leukocyte, platelet, and particularly, lymphocyte counts at the time of admission.[] Some patients appear acutely ill, with some weakness and respiratory findings, whereas others appear only mildly ill.[] Marked hyperglycemia, perhaps related to corticosteroid use, and elevated creatinine levels also occur. 16 In Thailand, 15 an increased risk of death was associated with decreased[]

  • Dengue Fever

    The commonest form has an incubation period of 5-8 days followed by the onset of a fever, violent headache, chills, retroorbital pain, with a rash developing after 3-4 days[] Panel D shows characteristic diffuse macular rash that appears after recovery from the acute illness in an adult patient with dengue.[] […] of leukocytes and platelets.[]

  • Meningitis

    Abnormalities include increased opening pressure ( 200 mm of H 2 O), increased leukocytes ( 4/mm 3 ), elevated protein ( 50 mg/dL), or decreased glucose ( 60 mg/dL), which[] […] concentration decreased by 6 percent.[] For the patients in the placebo group the lactate, leukocyte, and protein concentrations increased by 5 percent, 31 percent, and 13 percent, respectively, and the glucose[]

  • Rocky Mountain Spotted Fever

    BACKGROUND/OBJECTIVES: Rocky Mountain spotted fever (RMSF), a lethal tick-borne illness, is prevalent in the south central United States. Children younger than 10 years old have the greatest risk of fatal outcome from RMSF. The objective of the current study was to review pediatric cases of RMSF seen in the[…][]

  • Yellow Fever

    Key Points There is a large, ongoing outbreak of yellow fever in multiple states of Brazil . Since early 2018, a number of unvaccinated travelers to Brazil contracted yellow fever; many of these travelers were infected on the island of Ilha Grande (Rio de Janeiro State). Several have died. Travelers to Brazil should[…][]

  • Colorado Tick Fever

    J Virol . 1993 Apr; 67(4): 2389–2395. This article has been cited by other articles in PMC. Abstract Significant neutropenia, as well as thrombocytopenia and a mild anemia, occurs in patients infected with Colorado tick fever virus. In this study, human bone marrow CD34 cells and KG-1a cells, a human hematopoietic[…][]

  • Viral Meningitis

    ill, i.e. patients who would have been (and were) admitted and empirically treated irrespective of CSF findings.[] There is also increased anaerobic glycolysis by leukocytes and brain cells.[] In sum, in a non-toxic appearing, immunocompetent adult a completely normal CSF (including normal opening pressures) is highly reassuring in ruling-out bacterial meningitis[]

  • Doxycycline

    The acute phase (approximately 7 days) presents as an acute febrile illness with symptoms including headache (can be severe and include retroorbital pain and photophobia),[] Seroconversion typically occurs 7–15 days after symptoms appear, and 90% of patients seroconvert by the third week of illness.[] Undesirable blood effects (leukocyte decrease) were reduced when Dox was targeted to tumour tissue using the QA function.[]
