Background. A population-based prevalent cohort of 150 clinical definite multiple sclerosis (MS) cases (102 women; 48 men) ascertained on January 1, 1977, Saskatoon, Saskatchewan, was found to have a familial rate of MS as 17.3%. Objectives. To determine the occurrence of familial MS cases and the frequency of MS among the biological relatives of the study cohort. Methods. The search for new fa...

Employing a quasi-experimental design, this study explored the long-term effects of different childrearing ecological contexts. Participants were 131 adolescents (aged 16-18) from four groups: some who lived in a city, some from a kibbutz familial setting, some from a kibbutz communal setting, and a transitional group that included adolescents raised in a communal setting as young children who ...

Familial hyperekplexia, also called startle disease, is a rare neurological disorder characterized by excessive startle responses to noise or touch. It can be associated with serious injury from frequent falls, apnea spells, and aspiration pneumonia. Familial hyperekplexia has a heterogeneous genetic background with several identified causative genes; it demonstrates both dominant and recessive...

Background. A discoid meniscus is a thickened variant of the normal C-shaped meniscus prone to injury. Discoid medial meniscal tears have rarely been reported within families and may suggest familial or developmental origins. Methods. We report the cases of two Caucasian brothers with symptomatic discoid medial meniscus tears. A literature review was conducted addressing discoid medial meniscus...

BACKGROUND Since the use of computed tomography and magnetic resonance imaging, colloid cysts (CCs) are discovered more frequently and subsequently their true incidence exceeds the numbers previously estimated. In 1986, the first familial case was reported in two identical twin brothers. To date, a total of 17 of these cases have been reported, all differing in the pattern of affected family me...

aplasia cutis conginita (acc) is a condition characterized by congenital absence of skin, usually on the scalp. acc can occur as an isolated condition or in the presence of other congenital anomalies. here we describe a case of a 16 days old baby girl with an isolated acc of the scalp. her elder two siblings have been diagnosed with acc with concomitant cardiac or limb anomalies. the patient wa...

background: it is presumed that gastric cancer has several etiologies. first-degree relatives of patients with gastric cancer are suggested to be at higher risk compared to others. this is the first study aimed at estimating this risk, using meta-analysis of case-control studies. materials and methods: all records prior to february 2008 in pubmed and embase were searched for case-control studie...

objective(s):familial mediterranean fever (fmf), an inherited autosomal recessive disorder, is frequently present among individuals of mediterranean origin. differences in the clinical manifestations of fmf between different ethnic groups have been documented. the aim of the present study was to determine the most common characteristics of fmf and the relationship between clinical findings and ...

in general, both common illnesses and rare diseases can develop in people and their relatives in families. therefore, taking family history is an effective screening tool to detect such diseases and patients should be aware of its importance in families’ health with updating information in regular visiting. for more information on identifying the genetic pattern of diseases, in this article, we...

background: familial mediterranean fever (fmf) is an autosomal recessive genetic disorder characterized by recurrent episodes of self-limited fever and serosal tissues inflammation. methods: to evaluate clinical symptoms and common genetic mutations in southwestern iranian patients with fmf, 20 unrelated patients were enrolled in this study based on clinical criteria. a panel of 12 common mefv ...
