OBJECTIVETo understand the incidence and relevant affecting factors of infant vitamin K deficiency bleeding (VKDB) in Shandong Province.

METHODSWith stratified cluster sampling, 28 156 live newborns from five districts and six counties were surveyed for the condition of bleeding from their birth to 6 months based on standard diagnostic criteria. A 1:2 matched case-control study of VKDB was performed.

RESULTSAn overall incidence of VKDB was 3.27 per thousand in Shandong; higher in the rural areas (4.96 per thousand ) than in the urban areas (1.19 per thousand ). Most of the bleeding cases were breast-fed babies (about 95.57%) and incidence of VKDB in pre-term babies (22.52 per thousand ) was higher than that in term ones (2.96 per thousand ). Mothers' drug taking during pregnancy, asphyxia at birth, breast-feeding and illness within two weeks after birth were risk factors for it. Use of vitamin K after birth and bottle-feeding were protective factors for it.

CONCLUSIONSIncidence of VKDB is higher in Shandong Province, as compared to other areas all over the country at the same time period. It is very important to prevent VKDB, focusing on high-risk babies in the rural areas, including those of preterm, breast-fed and suffering illness after birth.

Hemorrhagic disease of newborn by combined blood clotting factor deficiencies is very rare. Combined deficiency of factor V and factor VIII is the most common form among these cases, and inherited by autosomal recessive trait. Clinical findings are easy bruising, post-traumatic bleeding and bleeding after tooth extractions, and the main laboratory findings are prolonged partial thromboplastin time (PTT) and prothrombin time (PT) that are different from hemophilia A only with prolonged PTT. We experienced a case of combined congenital deficiency of factor V and factor VIII in a 1-day-old boy. We report the case with brief review of literature.

PURPOSE: This study is to evaluate the Brain CT manifestations of late hemorrhagic disease of the newborn. METHODS: We evaluated 13 cases with late hemorrhagic disease of the newborn, for whom brain CT scans were performed. Clinical indications for brain CT scan were mental changes(n=5), vomiting(n=2), irritability(n=2), seizure(n=3), and lethargy(n=1). We analyzed the result of the brain CT findings with attention to anatomic locations of hemorrhage and characteristics of hemorrhagic manifestations. RESULTS: Only one patient in 13 patients was normal on brain CT scan, and 12 patients showed hemorrhagic lesions. Among 12 patients, 5 cases had single hemorrhagic lesion(3 subdural hemorrhages and 2 intracerebral hemorrhages, and 7 cases had multiple lesions, in which subdural hemorrhage and subarachnoid hemorrhage were common respectively. The other common brain CT findings except hemorrhagic lesion were the mass effects with ventricle compression(n=11), midline shifting(n=6), ventricular dilatation(n=7), and fluid-fluid levels in hemorrhagic lesion(n=9). CONCLUSION: The common intracranial hemorrhages of late hemorrhagic disease of the newborn were subdural and subarachnoid hemorrhages. The associated CT findings were mass effect and fluid-fluid levels. Intracranial hemorrhage in late hemorrhagic disease of newborn could massively occurr. Thus brain CT scan should be done if any symptom for neurologic abnormality was present.

Background: Intracranial hemorrhage (lCH) is a common disease with high rate of mortality and neurological sequel. Objectives:to estimate preventive effectiveness of intracranial hemorrhage by vitamin K1 and K3 for newborns just after birth". Subjects and methods: An epidemiological, randomized control study with intervention was conducted. The study included all children under 3 months with and without ICH during period 1/1/2000 -30/6/2004 living in Hatay province. Among them all the newborns during period 1/6/2002 - 30/6/2004 were injected either 1 mg vitamin K1 or K3. Results: Children injected with vitamin K in the intervention period were followed up in three months and evaluated by a united process. Effects of intervention were calculated by preventive value. 62.057/82069 newborns were injected vitamin K1 or Vitamin K3 (25.725 newborns were injected Vitamin K1; 36.332 newborns were injected vitamin K3). Single dose 1M reduced the rate of ICH in infants: The morbidity changed from 3.3\ufffd?to 0.82\ufffd? the prevention value was 96%. There were no complications and side effects of vitamin K injections reported. Conclusions: Injection of vitamin K1 and K3 have similar preventive effectiveness. Vitamin K injection 1M with recommended dose was safe for newborns.\r\n', u' \r\n', u'\r\n', u'

BACKGROUND/AIMS: Recently, many cases of vitamin K-dependent coagulopathy of unknown origin have been reported. Such patients lack any relevant family history and have no systemic disease, raising suspicion of superwarfarin intoxication. We evaluated individual risk factors causing coagulopathy and hemorrhagic symptoms in patients with suspected superwarfarin intoxication. In addition, we determined how to effectively treat vitamin K-dependent coagulopathy caused by suspected superwarfarin intoxication. METHODS: Seven patients with suspected superwarfarin intoxication who lacked any definitive history of rodenticide ingestion were included. Thirty-one patients initially diagnosed with rodenticide poisoning were also included. We performed a retrospective chart review of all subjects and examined clinical data including patient demographics and medical histories. RESULTS: Patients initially diagnosed with rodenticide poisoning were divided into two groups, one of which had a laboratory abnormality (prothrombin time [PT] > 13 seconds) and another group with PTs in the normal range. There was no significant difference between the two groups in any of age, gender, the extent of chronic alcohol consumption, the causative rodenticide, psychiatric problems, ingestion of drugs interacting with warfarin, the extent of intoxication, or the type of ingestion attempt. The albumin level of the former group was significantly lower than that of the latter group (p = 0.014). Furthermore, a significant difference between the two groups was evident in terms of simultaneous ingestion of rodenticide and alcohol (p = 0.023). CONCLUSIONS: Most patients with superwarfarin poisoning did not exhibit any complication. When such complications were evident, they were associated with serum albumin level and coingestion of rodenticide and alcohol.
