We report on a 13-year-old boy with temporal lobe epilepsy associated with left hippocampal sclerosis and a contralateral arachnoid cyst in the middle cranial fossa (ACMCF). Chronic intracranial ...recording from subdural grid electrodes showed the left medial temporal lobe to be the ictal onset zone. After left anterior temporal lobectomy with hippocampectomy, seizure control was improved. ACMCF was not considered the direct cause of epilepsy; instead the seizures were attributed to hippocampal sclerosis.
We demonstrate simultaneous WDM signal generation using time lens based optical Fourier transformation. Using a single AlGaAs on-insulator waveguide, 256 1-Gb/s WDM channels with 14-GHz spacing are ...generated from 1570-nm to 1600-nm, and transmitted over a 100-km unamplified link.
THe authors review recent progress in the use of time lens based optical Fourier transformation for advanced optical signal processing, with focus on all-optical generation, detection and format ...conversion of spectrally-efficient OFDM and N-WDM signals.
We demonstrate an SDM-WDM-PON system with symmetric aggregated capacity of 120 Gbps (3×scores, 4×wavelengths, 10 Gbps each). The light sources are distributed through the center core of the 7-core ...fiber, facilitating colorless ONU.
We presented the clinicopathological features of 8 cases of intraventricular neurocytoma, which was a rare, benign tumor of neuronal origin and affected young patients. In each case the ...intraventricular tumor existed near the foramen of Monro and/or body of the lateral ventricle, and was associated with ventricular dilatation. A CT scan demonstrated a well-circumscribed iso- or hyperdense mass with some calcification, intratumoral cysts of various sizes and a heterogeneous enhancement. MRI, which was performed in 4 cases, confirmed a mass of isointense or slightly hyperintense on T 1-weighted images, and with multiple sites of attachment (mainly to the septum pellucidum and the head of the caudate nucleus). While these neuroimaging features are helpful in eliminating alternative diagnosis such as ependymomas, choroid plexus papillomas, subependymal giant cell astrocytomas and meningiomas, age of the patient and the tumor location within the lateral ventricle are important features for differential diagnosis.
We have developed hybridoma cell lines, each of which secretes a monoclonal antibody (MoAb) to rat renal and hepatic tissue antigens, from Lewis rat with Heymann's nephritis. Three antibodies bind to ...the brush border of proximal tubular epithelium (BB), one in a fine net-like pattern (no. 3-11), another one in a coarse granular pattern (no. 1-8) and the third one in a typical pattern (no. 3-9). Three antibodies bind to glomerulus in characteristic patterns but not to BB. After repeated intravenous injections of MoAb (no. 3-11), granular mesangial deposits of rat IgG were observed and of MoAb (no. 1-8), fine granular deposition along capillary walls. These monoclonal autoantibodies should be of value in research on the mechanism of autoimmune membranous nephropathy.
The clinicopathologic features of seven paediatric patients with pituitary adenomas (2 male, 5 female; mean age 14.3 years) were reviewed. There were three non-functioning adenomas, three ...prolactinomas, and one growth hormone producing adenoma. Five pat ients presented with visual field deficits, and six patients had endocrine symptoms, which included menstrual irregularities in all female patients, pubertal delay in two females, and growth delay and gigantism in one case each. On neuroimaging studies, five adenomas showed parasellar extension, while the remaining two prolactinomas were intrasellar microadenomas. While two patients with prolactinomas received good results with bromocriptine treatment alone, the remaining five patients underwent either craniotomy or transsphenoidal surgery. Postoperatively, visual disturbances improved markedly in all patients. Two patients also received replacement hormonal therapy. While six patients have been stable for 3.6 years on average, one non-functioning tumo ur recurred 2 years after the initial transcranial subtotal resection of the tumour. Although there are still many unknowns concerning the biology and optimal treatments for paediatric pituitary adenomas, many of them are assumed to be relatively rapidly growing tumours, while others merely have an earlier tumour genesis than in adults.
The authors describe two male patients with prolactinomas which were incidentally found either during the course of a complete work up for headache or after minor head trauma. Since these tumours ...were located mainly in the sphenoid bone and did not show any upward growth to the suprasellar region, they were initially thought to be a primary skull base tumour; however, the serum prolactin levels of these patients were 1 179ng/ml and 3260ng/ml, respectively. The authors thus emphasise the need to reco gnise this peculiar infrasellar growth pattern of prolactinoma.
