Oral bleeding: Child abuse alert

T Stricker
Abstract: Physicians must be aware of histories, behaviours and physical findings of maltreated children. We report two cases of physical child abuse in which the initial symptom was oral bleeding. In both cases, the diagnosis was delayed and was made only after severe injuries were inflicted. Injuries to the oral cavity and oral bleeding of uncertain origin in infants should be considered seriously and should be carefully assessed in relation to adequacy of history to explain the mechanism of injury. When an infant has been injured and no adequate explanation is available to account for the mechanism, inflicted injury must be suspected and evaluated, so that in cases of child maltreatment, diagnosis and protection of the child from further injury can take place as early as possible.

Major differences in bleeding symptoms between factor VII deficiency and hemophilia B

Summary.,Background:,The autosomally-inherited factor VII (FVII) deficiency and X-linked hemophilia B offer an attractive model to investigate whether reduced levels of FVII and FIX, acting in the initiation and amplification of coagulation respectively, influence hemostasis to a different extent in relation to age and bleeding site. Methods:,Hemophilia B patients (n = 296) and FVII-deficient males (n = 109) were compared for FVII/FIX clotting activity, F7/F9 genotypes and clinical phenotypes in a retrospective, multi-centre, cohort study. Results:,Major clinical differences between diseases were observed. Bleeding occurred earlier in hemophilia B (median age 2.0 years, IR 0.9,5.0) than in FVII deficiency (5.2 years, IR 1.9,15.5) and the bleeding-free survival in FVII deficiency was similar to that observed in ,mild' hemophilia B (P = 0.96). The most frequent disease-presenting symptoms in hemophilia B (hematomas and oral bleeding) differed from those in FVII deficiency (epistaxis and central nervous system bleeding). Differences were confirmed by analysis of FVII-deficient women. Conclusions:,Our data support the notion that low FVII levels sustain hemostasis better than similarly reduced FIX levels. On the other hand, minute amounts of FVII, differently to FIX, are needed to prevent fatal bleeding, as indicated by the rarity of null mutations and the associated life-threatening symptoms in FVII deficiency, which contributes towards shaping clinical differences between diseases in the lowest factor level range. Differences between diseases are only partially explained by mutational patterns and could pertain to the specific roles of FVII and FIX in coagulation phases and to vascular bed-specific components.

Management of oral bleedings with recombinant factor VIIa in children with haemophilia A and inhibitor

HAEMOPHILIA, Issue 1 2005
P. Laguna
Summary., Dental extraction in patients with haemophilia A and high-titre inhibitor is always a high-risk procedure, which often presents a lot of problems associated with bleeding. Prothrombin complex concentrates or recombinant activated factor VII (rFVIIa) has been used to control bleeding. rFVIIa was administered to five boys with severe haemophilia A complicated with inhibitor, who underwent seven dental extractions. The age of the patients ranged between 8 and 13 years (median 10 years). The concentrate was administered in doses of 90,100 ,g kg,1 body weight. Duration in the therapy and intervals between rFVIIa doses depended on the severity of bleeding. rFVIIa was proven to be highly effective and no side-effects of the product were observed. [source]
