BACKGROUND The purpose of this study was to evaluate the potential association of five (p.P47S, p.R72P, PIN3 Ins16bp, p.R213R and r.13494g>a) polymorphisms of TP53 with the risk of developing breast cancer in North Indian Punjabi population. METHODS We screened DNA samples of 200 sporadic breast cancer patients (197 females and 3 males) and 200 unrelated healthy, gender and age matched indivi...
We compared the clinical, psychological and pharmacological characteristics of patients with familial migraine and patients with sporadic migraine. Five hundred and thirty consecutive new patients attending our Headache Center over a two-year period were involved in the study. The patients were divided into two groups: A. Familial migraine (famM)--at least one first-degree relative affected; B....
BACKGROUND The incidence of sporadic inclusion body myositis (sIBM) has been much lower in Japanese than in Western populations. Because of a few reports on Asian populations, it is unclear whether the clinical characteristics of sIBM are identical in Caucasian and Japanese patients. METHODS We compared 18 patients with sIBM, divided into 3 groups by age-of-onset, with previous cohort studies...
DNA amplification at chromosomal region 20q12-q13, which is common in breast cancer, has recently been described also in ovarian tumors. We studied the amplification of the recently identified candidate oncogenes in this region in 24 sporadic, 3 familial and 4 hereditary ovarian carcinomas, and in 8 ovarian cancer cell lines. High-level amplification of at least one of the five nonsyntenic regi...
BACKGROUND Prospective national screening and surveillance programmes serve a range of public health functions. Objectively determining their adequacy and impact on disease may be problematic for rare disorders. We undertook to assess whether objective measures of disease surveillance intensity could be developed for the rare disorder sporadic Creutzfeldt-Jakob disease (CJD) and whether such me...
Porphyria cutanea tarda (PCT) results from a metabolic block in heme synthesis at the level of uroporphyrinogen decarboxylase. We measured the activity of one of the enzymes preceding it in the heme biosynthetic pathway, porphobilinogen deaminase (PBGD; EC 4.3.1.8), in erythrocytes of 47 patients with symptomatic or asymptomatic familial or sporadic PCT. PBGD activity was significantly increase...
OBJECTIVE To assess the outcome of conservative management of vestibular schwannoma. STUDY DESIGN Observational study. SETTING Tertiary referral centre. PATIENTS Four hundred and thirty-six patients with vestibular schwannoma (490 tumours), including 327 sporadic tumours and 163 tumours in 109 patients with neurofibromatosis type two. MAIN OUTCOME MEASURES The relationship of tumour gro...
Amyotrophic lateral sclerosis is a degenerative disorder of motor neurons that typically develops in the 6th decade and is uniformly fatal, usually within 5 years. To identify genetic variants associated with susceptibility and phenotypes in sporadic ALS, we performed a genome-wide SNP analysis in sporadic ALS cases and controls. A total of 288,357 SNPs were screened in a set of 1,821 sporadic ...
Restorative proctocolectomy is recognized as the standard procedure for colitic cancer in patients with ulcerative colitis (UC). However, whether this represents the optimal procedure for UC patients with sporadic cancer remains questionable, as functional quality of life differs substantially between patients with proctocolectomy and partial resection. This study considered possible problems a...
BACKGROUND The occurrence of familial forms of sarcoidosis (OMIM 181100) suggests a genetic predisposition. The involvement of butyrophilin-like 2 (BTNL2) gene (rs2076530 variant) has to be investigated. RESULTS The study performed independent analyses of BTNL2 polymorphism, clinical phenotypes, and outcomes in familial vs. sporadic presentations in 256 sporadic and 207 familial cases from 14...
