The Family

The aim of this research was to determine risk for family appearance of the recurrent headache (non-migraine and migraine). The recurrent headache can be understood as being a heterogeneous state, consisting of some more, still not found, hereditary disposition factors which altogether, interacting with surrounding factors give the recognizable clinical picture. The current heredity concept suggests multifactor heredity. The research was conducted in Vojvodina, the Northern Province of Serbia. The population of Vojvodina is around 2 million people belonging to more than 20 different ethnic groups. During the 20 years period (1988-2008), 30363 children aged 3 to 17 years were tested, independent of the place of birth. The presence of headaches similar to those tested was compared among all the members of the family within three generations. Positive family data of the recurrent headaches was detected among 98,6% children with migraine headaches, 64,7% children with non- migraine headaches, and 32,4% children without recurrent headaches. The relation among the members of the nuclear family (contingency quotient of 0,429) is significantly stronger than the relation to the members of wider family (contingency quotient of 0,338). The probability of a child having the migraine headache, and not the non-migraine one, is 0,664 for a mother, 0,644 for a father, 0,411 for a father`s mother, - 0,175 for a mother`s mother, 0,165 for a mother`s father, and - 0,102 for a father`s father having similar recurrent headaches.

Harmonious Family

This study aims to determine how the experience of being a good stepmother for children with cerebral palsy (CP children). With the stigma of a stepmother who tends to be negative, is it still possible to be a good stepmother for a CP child? In answering this question, the writer uses Talcot Parson's functionalism-structuralist theory to see the fulfillment of certain conditions for the creation of a stable/harmonious family. Data collection is done by interview and observation techniques. This research concludes that stepmothers are not always bad, not ideal, or evil-tempered. The determinants of how a stepmother is accepted are inseparable from the background of her life and acceptance and support from the family, both the nuclear family or extended family.[Penelitian ini bertujuan untuk mengetahui bagaimana pengalaman menjadi ibu tiri yang baik bagi anak dengan cerebral palsy (anak CP). Dengan stigma ibu tiri yang cenderung negatif, masih mungkinkah menjadi ibu tiri yang baik bagi seorang anak CP? Dalam menjawab pertanyaan tersebut, penulis menggunakan teori fungsionalisme-strukturalis dari Talcot Parson untuk melihat pemenuhan syarat tertentu demi terciptanya keluarga yang stabil/harmonis. Pengumpulan data dilakukan dengan teknik wawancara dan observasi. Penelitian ini menyimpulkan bahwa ibu tiri tidak selalu buruk, tidak ideal, atau berperangai jahat. Adapun faktor penentu bagaimana ibu tiri diterima tidak terlepas dari latar belakang kehidupannya dan penerimaan dan dukungan dari keluarga, baik keluarga inti atau keluarga besar.]

Background: In order to analyze the prevalence of Raynaud’s syndrome in diseases such as scleroderma and Sjögren’s syndrom – a meta-analysis of published data was performed. Methods: The PubMed data base of the National Library of Medicine was used for studies dealing with Raynaud’s syndrome and scleroderma or Raynaud’s syndroem and Sjögren’s syndrom respectively. The studies found provided data sufficient to estimate the prevalence of Raynaud’s syndrome. The statistical analysis was based on methods for a fixed effects meta-analysis and finite mixture model for proportions. Results: For scleroderma a pooled prevalence of 80.9% and 95% CI (0.78, 0.83) was obtained. A mixture model analysis found four latent classes. We identified a class with a very low prevalence of 11%, weighted with 0.15. On the other hand there is a class with a very high prevalence of 96%. Analysing the association with Sjögren’s syndrome, the pooled analysis leads to a prevalence of Raynaud’s syndrome of 32%, 95% CI(26.7%, 37.7%). A mixture model finds a solution with two latent classes. Here, 38% of the studies show a prevalence of 18.8% whereas 62% observe a prevalence of 38.3%. Conclusion: There is strong variability of studies reporting the prevalence of Raynaud’s syndrome in patients suffering from scleroderma or Sjögren’s syndrome. The available data are insufficient to perform a proper quantitative analysis of the association of Raynaud’s phenomenon with scleroderma or Sjögren’s syndrome. Properly planned and reported epidemiological studies are needed in order to perform a thorough quantitative analysis of risk factors for Raynaud’s syndrome.
