Headache and family history

In two headache questionnaire surveys we inquired about the occurrence of headache in the mothers, fathers, siblings and children of the respondents. In total, 633 people completed valid questionnaires, 260 in the first survey and 373 in the second. The hypothesis was that familial headache occurrence would be positively associated with headache frequency. In each survey, the regression of headache frequency on the number of parents having headache was highly significant. Neither sex nor the sibling and children variables were significant predictors. In the cross-tabulations of the parental occurrence of headache with headache frequency we saw a clear "break-point" between the "no headache" and the headache frequency categories studied. For the final analyses the dichotomy "headache/no headache" was related in fourfold tables to headache occurrence in the father and the mother separately, and to the number of headache parents. The positive associations were not simply due to the large number of migraine cases since they remained after removing the migraineurs.     

The influence of reported paternal attitudes on the decision to breast-feed

Objective: To identify factors that influence a woman's decision to breast-feed.
Methodology: Five hundred and fifty-six women were recruited from the maternity wards of two Perth hospitals. Data were collected from a self-administered questionnaire completed by participants prior to discharge. Logistic regression analysis was used to determine factors influencing the initiation of breast-feeding.
Results: At discharge from hospital 83.8% of women were breast-feeding, including 6% who were giving complementary formula feeds. After controlling for potentially confounding demographic and biomedical factors, the father's reported preference for breast-feeding was found to be the most important factor influencing a woman's decision to breast-feed (OR 10.18).
Conclusion: Fathers participate in and influence the choice of infant feeding method and should be included in breast-feeding discussions.     

Margin of safety for discharge after apnea in preterm infants

OBJECTIVE: Most neonatologists include an apnea-free period in the criteria for the discharge of preterm infants. However, the length of time one should wait after the cessation of apnea before sending an infant home without a monitor is debated. We undertook this study in an attempt to define a minimal and safe observation period between the time of the last apnea episode and discharge. METHODS: We reasoned that in infants with idiopathic apnea of prematurity, the intervals between days on which apnea occurs gradually increase until some point at which clinically significant apnea ceases. Therefore, knowledge about the intervals between days on which apnea occurred just before the last apnea would provide a reasonable estimate of the minimal safe observation interval between the last apnea and discharge. We reviewed the charts of 266 infants born in 1993 and 1994 at 相似文献   

Preservice early childhood students' perceptions of written feedback on their essays

Lecturer feedback on students' essays is important to the quality of the experience students have at university (Norton & Norton, 2001). The aim of the present study was to investigate whether early childhood students at one university actually read lecturer feedback on their essays and, if they did, what they found helpful and not helpful to their learning. Feedback was defined as 'giving students information on how well or how poorly they are doing in their academic work' (Hounsell, 1987, p. 109). Using the Vygotskian concept of learning as a socially shared activity, qualitative data were collected from second-year students from a four-year early childhood degree programme via an anonymous survey and four focus groups. Major findings were that, in contrast with studies of students in other programmes, early childhood students read lecturer feedback on their essays and used feedback that was detailed and explanatory as a learning tool. Types of feedback students found to be most and least useful were identified.     

Fibrin glue assisted amniotic membrane graft reconstruction of conjunctival fornix and canthus following excision of conjunctival tumours

Conjunctival tumors involving non-limbal locations, such as the fornix and canthus, are typically excised using a “non-touch” technique, often with a wide surgical margin. Reconstruction of these large defects can be difficult due to the contour of the ocular surface and are often complicated by shortening of the fornix, symblepharon formation, and restriction of eye movements. In our experience, the use of amniotic membrane grafts combined with the sealant properties of fibrin glue such as Tisseel® has improved our surgical outcomes during the reconstruction phase. We would like to highlight and describe our surgical technique using fibrin glue and squint hooks to aid amniotic membrane graft reconstruction for surgically challenging locations in the fornix and canthus following excision of conjunctival lesions, with excellent surgical outcomes.
