In Morocco, Alzheimer's disease (AD) affects almost 30,000 individuals, and this number could increase to 75,000 by 2020. To our knowledge, the genes predisposing individuals to AD and predicting disease incidence remain elusive. In this study, we aimed to evaluate the genetic contribution of mutations in the amyloid precursor protein (APP) gene exons 16 and 17 to familial and sporadic AD cases. Seventeen sporadic cases and eight family cases were seen at the memory clinic of the University of Casablanca Neurology Department. These patients underwent standard somatic neurological examination, cognitive function assessment, brain imaging, and laboratory tests. Direct sequencing of exons 16 and 17 of the APP gene was performed on genomic DNA of AD patients. In this original Moroccan study, we identified seven novel frameshift mutations in exons 16 and 17 of the APP gene. Interestingly, only one novel splice mutation was detected in a family case. There is a strong correlation between clinical symptoms and genetic factors in Moroccan patients with a family history of AD. Therefore, mutations in APP gene exons 16 and 17 may eventually become genetic markers for AD predisposition. 相似文献

Hepatic involvement in Wilson disease (WD) manifests as a diffuse chronic disease in the majority of patients. However, in a subset of patients focal liver lesions may develop, presenting with a wide range of imaging features. The majority of focal liver lesions in patients with WD are benign nodules, but there are reports that have described malignant liver tumors or dysplastic nodules in these patients. Because of the possibility of malignant transformation of liver nodules, major concerns have been raised with respect to the management and follow-up of patients with WD in whom focal liver lesions have been identified. The assessment of liver involvement in patients with WD is generally performed with ultrasonography. However, ultrasonography conveys limited specificity so that magnetic resonance (MR) imaging is often performed to improve lesion characterization. This review was performed to illustrate the spectrum of MR imaging features of focal liver lesions that develop in patients with WD. It is assumed that familiarity with the MR imaging presentation of focal liver lesions in WD may help clarify the actual nature of hepatic nodules in patients with this condition. 相似文献

Recombinant GH (rGH) treatment does not invariably correct height deficits in GH-deficient children once puberty has begun. The addition of GnRH analogs (GnRHa) to delay puberty has been advocated, but published results are few and sometimes conflicting. We retrospectively compared GH-deficient children treated with rGH and GnRHa for at least 1 yr after entering puberty and having attained their final height (n = 23) with a matched control group treated only with rGH. Overall, combined therapy did not significantly increase final height relative to rGH alone. However, the shortest girls at the onset of puberty (<25th percentile) benefited more than the tallest (>75th percentile) in both final height relative to predicted height and pubertal catch-up growth. In the control group, patients having experienced intrauterine growth retardation (IUGR) attained a lower mean final height than patients without IUGR (difference significant in boys, but not in girls). In the combined therapy group, IUGR did not affect the final height of either sex. Our results suggest that two populations might benefit most from combined GnRHa and rGH therapy: girls particularly short at the onset of puberty and patients who had experienced IUGR. Further prospective studies are required to confirm these preliminary hypothesis. 相似文献

Metastatic tumors in the gastrointestinal tract are rare with an overall prevalence of 1-4 per cent in the postmortem series. Lung cancer, renal cell carcinoma, breast carcinoma and malignant melanoma are considered the most common primary tumors metastatic to the small bowel. Local duodenal metastasis from colonic cancer and cecum have been reported, but metastasis to the duodenum from rectosigmoid adenocarcinoma has not been reported before. We report the first case of metastasis in the duodenum from an adenocarcinoma of the rectum presented as a recurrent acute prerenal azotemia caused by volume depletion which had resulted from duodenal obstruction. 相似文献

The mutation FV Leiden (G1691A) is the most common mutation worldwide with a variable allelic frequency between countries. More frequent in the European and Caucasian populations and rare or absent in African native population, the FVL was studied in the Moroccan population (They-They et al. Ann Hum Biol 37(6):767–777, 2010) and is totally absent as reported previously by (Mathonnet et al. Thromb Haemost 88(6):1073–1074, 2002). Here, another mutation in FV (Q773Term) was detected in a Moroccan patient, which took our interest for this study and establishes the first epidemiological database for future associated studies concerning neurovascular diseases. 相似文献

The muscular dystrophy is a group of inherited disorders characterized in the most of cases by progressive muscle weakness. The best known are X-linked disorder Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). BMD is a milder form of the disease with a later age of onset and a slower clinical progression. The DMD gene, located on Xp21, is the largest human gene in the human genome (2.3 Mb). DMD gene consists of 79 exons and codes for dystrophin protein. A 9-year-old boy, who experienced symptoms of the disease, was admitted to the Casablanca University Children’s Hospital. The patient, with no known family history of significant muscle disease, was first examined at 4 years of age because of walking difficulties and a limited hands force. Blood tests revealed elevated serum levels of creatine kinase (7.60 U/L). The electromyogram showed myopathic changes, consisting of polyphasic potentials, and the muscular biopsy revealed dystrophic aspect. Analysis of the dystrophin-encoding gene by PCR deletion analysis of the dystrophin gene was performed by multiplex PCR primer sets of Chamberlain and Beggs. The analysis showed a deletion of exons 45 to 49. Mother genetic testing showed the heterozygosis deletion. 相似文献
