Split cord malformation in two sisters

WOS: 000179287900006PubMed ID: 12411715Split cord malformations (SCMs) are uncommon congenital spinal anomalies and are seen mostly in females. SCMs in siblings are extremely rare. We report two sisters with SCM. These 10- and 8-year-old girls were the first and second children, respectively, of nonconsanguineous parents. Both sisters had a hypertrichosis and pes cavus deformity. The first child had a type I SCM and the second a type II SCM. They had additional spinal lesions, with tethering of the spinal cord. They were operated on and showed an uneventful postoperative course. All reported siblings with SCM have been female. The present data are not sufficient to account for the sex predilection. Therefore, further data and knowledge are needed. (C) 2002 S. Karger AG, Base

Conventional and diffusion-weighted MR imaging of intracranial tuberculomas

WOS: 000179908900003PubMed ID: 12485250Intracranial tuberculoma is a rare form of central nervous system tuberculosis. We here report on conventional and diffusion-weighted cranial MR images of a non-immunocompromised patient with multiple intracranial tuberculomas, tuberculous lymphadenitis and pulmonary tuberculosis. Conventional MR imaging revealed multiple ring-enhancing mass lesions. At follow-up MR, appearances of both edema and number and size of nodules were decreased. Diffusion-weighted MR was normal and normal ADC values were found in this case of tuberculomas

DWI findings of periventricular ischemic changes in patients with leukoaraiosis

WOS: 000184800600006PubMed ID: 12821031In this report the diffusion-weighted imaging (DWI) findings and ADC values of leukoaraiosis (LA) and associated periventricular ischemic lesions were assessed. Seventy-eight patients with LA were examined with magnetic resonance imaging (MRI) and DWI. Twenty one patients (28%) were found to have focal acute white matter infarction on DWI which could not be detected and discriminated on the basis of MRI findings alone. LA and acute white matter infarction both showed hyperintensity on standard T2W MRI, whereas acute infarction revealed focal hyperintensity on DWI. Thirteen patients (16%) had chronic lacunar infarctions in the white matter. ADC values of LA, acute and chronic white matter infarctions were calculated and found to be significantly different from each other (P < 0.05). It is concluded that DWI is necessary in the detection of acute periventricular white matter infarction from LA. (C) 2003 Published by Elsevier Science Ltd

Evaluation of common vetch (Vicia sativa L.) as living mulch for ecological weed control in citrus orchards

Weeds are one of the most important problems in newly established orchards. Especially in organic orcharding, the importance of weed management is much more than conventional orcharding. Therefore, importance of alternative methods to chemical control of weeds is increasing. This study was conducted to quantify the effects of common vetch (Vicia sativa L.) as living mulch on weeds and evaluate the availability of common vetch in organic citrus production. The study was carried out in Mandarin orchard which was established specially for this research in research and implementation area of the Plant Protection Department of Çukurova University in Turkey, in a three-year-period. Living mulch and control plots were placed between rows in newly established mandarin orchard and plots were maintained at the same locations until the end of the experiment. In this study, effects of the living mulch application on density, cover proportion, biomass, dry weight and similarity index of weed species were investigated. Overall three-years results of the study were evaluated, living mulch application reduced weed density and cover proportion average of 42.8% and 45.9% respectively compare to control. Biomass and dry weight of weeds were also reduced by living mulch in all years of the experiment. The results indicate that living mulch application by common vetch is an important alternative weed suppression method for ecological weed management. ©2011 Academic Journals
