Postdural puncture headache in paediatric oncology patientsPurpose: Previous studies have not determined the correlation between dural puncture and postural headache in paediatric patients. Furthermore, no studies have evaluated the correlation between atypical headache and dural puncture iri the paediatric population. Therefore, we prospectively analyzed the incidence of typical postdural puncture headache (PDPHA) and atypical headache in paediatric ontology patients following dural puncture. Methods: The study population consisted of 66 paediatric patients undergoing 128 consecutive procedures, including 99 lumbar punctures and 29 bone marrow aspirations without concomitant lumbar puncture. Patients were prospectively randomized into four groups: Group I, preteens (< 13 yr) undergoing lumbar puncture, Group II, adolescents (13-21 yr) undergoing lumbar puncture, Group III, preteens undergoing bone marrow aspiration, and Group IV, adolescents undergoing bone marrow aspiration. The presence and description of headache was documented immediately after dural puncture or bone marrow aspiration, and on post-procedure days # I, 3 and 5 by personnel blinded to the type of procedure. Results: There was an increase in the incidence of headache (9. 1%) after lumbar puncture in patients < 21 yr relative to patients undergoing bone marrow aspiration (P < 0.05). No difference was found between the incidence of typical PDPHA after dural puncture in preteens and adolescents. There was also no difference in the incidence of atypical headache after dural puncture or after bone marrow aspiration among preteens and adolescents. Conclusions: Paediatric patients experience an increased incidence of typical postdural puncture headache after dural puncture compared with age-matched patients undergoing bone marrow aspiration only. Atypical headache is relatively common in the paediatric population after dural puncture or bone marrow aspiration.Objecdf: Les &udes ant&ieures n'ont pas &abli de correlation entre la ponction durale et ta c~phal~e posturale chez les patients pEdiatriques. En outre, aucune Etude de cette population n'a EvaluE le lien entre la cEphalEe atypique et la ponction durale. Par consequent, ~ la suite d'une ponction durale, nous avons analys~ de fa~on prospective I'incidence d'une cEphalEe de ponction postdurale (CPPD) typique et atypique chez des patients d'oncologie pEdiatrique. M~thode : La population de I'Etude 6tait constituEe de 66 patients de p6diatrie subissant 128 examens cons&utifs, comprenant 99 ponctions Iombaires et 29 ponctions m6dullaires sans ponction Iombaire concomitante. Les patients ont ~t~ r~partis au hasard en quatre groupes de fa~on prospective: Groupe I de pr6-adolescents (< 13 ans) subissant une ponction Iombaire; Groupe II d'adolescents (13-21 ans) subissant une ponction lombaire; Groupe III de prE-adolescents inscrits pour une ponction mEdullaire et Groupe IV d'adolescents pour une ponction mEdullaire.
