congenital neutropenia infantile genetic agranulocytosis.
cyclic neutropenia a chronic form marked by regular, periodic episodic recurrences, associated with malaise, fever, stomatitis, and various infections. Called also periodic neutropenia.
drug-induced neutropenia that caused by medications; the most common mechanisms are immunological (formation of antibodies destructive to neutrophils or of immune complexes that bind to neutrophils), followed by inhibition of granulopoiesis and direct damage to bone marrow or precursor cells of the granulocytic series.
idiopathic neutropenia agranulocytosis.
Kostmann's neutropenia infantile genetic agranulocytosis.
malignant neutropenia agranulocytosis.
neonatal neutropenia, alloimmune neutropenia in the newborn due to in utero incompatibility between its immunoglobulin G antigens and those of the mother's blood; the mother's blood produces antibodies that cross the placenta and sensitize fetal neutrophils. Affected infants may have fever, pneumonia, septicemia, and other infections that can be fatal. The condition eventually resolves as the infant's immunoglobulin replaces that from the mother.
periodic neutropenia cyclic neutropenia.
neutropenia recurring at regular intervals (14-45 days), in association with various types of infectious diseases, for example, stomatitis, cutaneous ulcers, furuncles, arthritis, and others.
Synonym(s): cyclic neutropenia
a chronic type of neutropenia that abates and recurs, accompanied by malaise, fever, stomatitis, and various types of infections.
cyclic neutropeniaA disorder characterized by episodic severe neutropenia occurring in 3-4 wk cycles, accompanied by maturational arrest of myeloid precursors in BM Clinical Fever, oral ulceration, cervical lymphadenopathy, multiple acute local infections which are rarely fatal Management If symptomatic, antibiotics–eg, aminoglycosides, penicillin

cyclic neutropenia (nōō´trəpē´nēə),
n a hereditary disease primarily afflicting young children and infants; characterized by flulike symptoms (weakness, tenderness in the pharynx, aching head, and fever) as well as stomatitis, periodontitis, and gingivitis; cycles every 3 to 4 weeks with painful lesions and damage to the alveolar bone; should be medicated with antibiotics prior to any oral surgery.

canine cyclic hematopoiesis
an abnormality of hematopoietic stem cells that results in detectable, cyclic fluctuations in numbers of circulating neutrophils. Affected dogs have an increased susceptibility to infections. The condition is inherited as an autosomal recessive in collies where it is occurs with a distinctive silver-gray coat color; called also gray collie syndrome.

cows demonstrating estrus regularly but not being submitted for mating; deferral of mating.
see cyclic nucleotide.
