2,555 Possible Causes for Patients Are Often Asymptomatic

  • Viral Lower Respiratory Infection

    Virus may be shed for up to three weeks post infection and also by patients with asymptomatic infections.[] Immunity following infection is poor and re-infections are common, although often subclinical.[]

  • Vitamin D Deficiency

    It is often seen in older people with osteoporosis.[] Supplementary requirements are therefore greater in patients with hyperparathyroidism.[] Diagnosing vitamin D deficiency Vitamin D deficiency is usually asymptomatic, but signs and symptoms can include muscle aches and particularly weakness (proximal limb girdle[]

  • Urinary Tract Infection

    Health care providers frequently struggle to differentiate UTI from asymptomatic bacteriuria, particularly in patients presenting with nonspecific symptoms.[] Most patients remain asymptomatic.[] However, antibiotic prescriptions for clinically suspected UTIs are often inappropriate.[]

  • Vaginitis

    Patients may present with vaginal discharge, but this condition is often asymptomatic.[] When symptoms occur, female patients often report malodorous discharge which can be associated with vulvo-vaginal irritation and vaginal spotting.[] Most men and a significant percentage of women are asymptomatic of TV infection.[]

  • Cystitis

    Moreover, catheterized patients often have pyuria and bacteriuria, thus, it is difficult to determine whether cystitis versus asymptomatic bacteriuria is present.[] It is often difficult to distinguish cystitis from asymptomatic bacteriuria in patients who are catheterized, have altered sensorium, or have neurogenic bladder, and it is[] Perhaps most important, it is often difficult to determine whether symptoms in a patient with bacteriuria are due to cystitis or to some other cause.[]

  • Acute Cystitis

    […] catheters) often have persistent asymptomatic bacteriuria and sometimes pyuria.[] Most patients remain asymptomatic.[] In patients with indwelling catheters, treatment of asymptomatic bacteriuria often fails to clear the bacteriuria and only leads to development of antibiotic-resistant organisms[]

  • Constipation

    A gluten-free diet often leads to improvement in the quality of life, even in patients who considered themselves asymptomatic at the time of diagnosis [ 58 ].[] […] celiac disease Many patients, especially those diagnosed during screening, report no symptoms even on detailed questioning, and despite the presence of characteristic intestinal[] […] small for gestational age infant Dental enamel defects Dyspepsia, early satiety, anorexia Depression and anxiety, moodiness and irritability Vitamin B 12 deficiency 4.3 Asymptomatic[]

  • Iron Deficiency

    Patients with iron deficiency anemia are often asymptomatic and have limited findings on examination.[] A more practical approach is to recheck the patient periodically; no further follow-up is necessary if the patient is asymptomatic and the hematocrit level remains normal.[] 7 BLOOD TRANSFUSION There is no universally accepted threshold for transfusing packed red blood cells in patients with iron deficiency anemia.[]

  • Musculoskeletal Lower Back Pain

    This elderly male patient, who was previously asymptomatic, developed low back pain and difficulty with urination.[] Due to its insidious nature, it is a difficult diagnosis and one that is often delayed.[]

  • Adenovirus Infection

    Detection of virus in stool may be useful for epidemiological investigation but is often positive for months after acute infection because of asymptomatic shedding.[] In immunocompromised patients, biopsy specimens may be very useful in documenting the cause of hepatitis or colitis, allowing identification of the virus or diagnostic histopathologic[]
