Results of cerebrospinal fluid (CSF) examinations from 77 high-risk neonates were reviewed. The mean CSF white cells (WBC) count was 4.5 cell/mm3, being two standard deviations above the mean 11.7 cells/mm3 in the full-term gestation neonate group; in the premature neonate one, the mean CSF WBC count was 5.1 cells/mm3, being two standard deviations above the mean 16.7 cell/mm3. PMNs (polymorphonuclear leukocytes) were present in less than 40% of those children, being the mean PMN percentage 4.2% and 0.6%, the mean ANC (absolute neutrophil count) was 0.3/mm3 and 0.06/mm3, in full-term gestation neonate group and premature neonate one, respectively. The mean CSF protein concentration is significantly greater in those premature neonates (101.2 mg/dl) compared with that in term neonates (77.6 mg/dl). The average glucose was just the same in both groups (67 mg/dl). All of these values were from patients who underwent nontraumatic cisternal puncture, with no red blood cells (RBC/mm3 = 0). Traumatic puncture, even up to 500 RBC/mm3, interfered on CSF parameters.

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
