Ganglioglioma with lytic skull lesions: a case report

WOS: 000247859000007PubMed: 17497058Gangliogliomas represent only 0.4% of central nervous system neoplasms and 1.3% of brain tumors. They are benign neoplasms with low morbidity and mortality and the patients usually present with seizures, but there has been no adult ganglioglioma with lytic skull lesion. A 49-year-old right handed woman suffering from generalized epileptic seizures was admitted to our hospital. She had also left hemiparesis with 4/5 motor strength. Magnetic resonance imaging and immunohistochemical studies revealed WHO Grade 11 ganglioglioma. Skull X-ray showed the lytic skull lesions. We have to consider gangliogliomas in the differential diagnosis of lytic skull lesions

A preliminary geoengineering assessment of Bazda antique underground quarries in, Sanliurfa, Turkey

ISRM International Symposium (EUROCK) -- SEP 23-26, 2013 -- Wroclaw, POLANDWOS: 000337166500008Geoengineering evaluation of man-made antique underground structures improves and provides important information on such structures. Harran City in, Sanliurfa Province of Turkey was constructed probably during Sumerian period BC 3000 (5000 years BP). The building stones consisting of limestones of Harran City were extracted from open-pit and underground quarries known as Bazda quarries. Bazda antique underground quarry pillars suffer some structural stability problems in terms of splitting of high pillars, roof falls, plane or wedge sliding and large sinkholes. The authors have initiated a collaborative integrated research program to map the antique underground quarries having working levels up to four floor, in-situ rock characterization, identification of stability problems, some geomechanical properties of surrounding rock. This paper describes the first preliminary studies on Bazda antique underground quarries and discusses its implications in modern geomechanics and geoengineering.Int Soc Rock Mech, Polish Soc Rock Mech, Wroclaw Univ Technol, Inst Geotechn & Hydrotech

Turkey's globally important biodiversity in crisis

Turkey (Turkiye) lies at the nexus of Europe, the Middle East, Central Asia and Africa. Turkey's location, mountains, and its encirclement by three seas have resulted in high terrestrial, fresh water, and marine biodiversity. Most of Turkey's land area is covered by one of three biodiversity hotspots (Caucasus, Irano-Anatolian, and Mediterranean). Of over 9000 known native vascular plant species, one third are endemic. Turkey faces a significant challenge with regard to biodiversity and associated conservation challenges due to limited research and lack of translation into other languages of existing material. Addressing this gap is increasingly relevant as Turkey's biodiversity faces severe and growing threats, especially from government and business interests. Turkey ranks 140th out of 163 countries in biodiversity and habitat conservation. Millennia of human activities have dramatically changed the original land and sea ecosystems of Anatolia, one of the earliest loci of human civilization. Nevertheless, the greatest threats to biodiversity have occurred since 1950, particularly in the past decade. Although Turkey's total forest area increased by 5.9% since 1973, endemic-rich Mediterranean maquis, grasslands, coastal areas, wetlands, and rivers are disappearing, while overgrazing and rampant erosion degrade steppes and rangelands. The current "developmentalist obsession", particularly regarding water use, threatens to eliminate much of what remains, while forcing large-scale migration from rural areas to the cities. According to current plans, Turkey's rivers and streams will be dammed with almost 4000 dams, diversions, and hydroelectric power plants for power, irrigation, and drinking water by 2023. Unchecked urbanization, dam construction, draining of wetlands, poaching, and excessive irrigation are the most widespread threats to biodiversity. This paper aims to survey what is known about Turkey's biodiversity, to identify the areas where research is needed, and to identify and address the conservation challenges that Turkey faces today. Preserving Turkey's remaining biodiversity will necessitate immediate action, international attention, greater support for Turkey's developing conservation capacity, and the expansion of a nascent Turkish conservation ethic.

Preliminary results of auditory brainstem implantation in prelingually deaf children with inner ear malformations including severe stenosis of the cochlear aperture and aplasia of the cochlear nerve.

OBJECTIVE: The aim of our study is to present the results of 11 children where auditory brainstem implantation (ABI) was successfully performed to restore hearing. STUDY DESIGN: Case presentation. This study was conducted at the departments of Otolaryngology and Neurosurgery at Hacettepe University Ankara, Turkey. PATIENTS: Between July 2006 and April 2008, 11 prelingual (30-56 mo) deaf children with several cochlear malformations had ABI. INTERVENTION: All patients were programmed and were enrolled in auditory verbal therapy sessions and family counseling programs at Hacettepe Auditory Verbal Center. The evaluation was performed at preimplant and again 1, 3, 6, 9, and 12 months post-switch on. MAIN OUTCOME MEASURES: The main test components composing this test battery were Ling 6 Sound Detection-Identification Test, Word Identification Test in Turkish, Meaningful Auditory Integration Scale, and Meaningful Use of Speech Scale. RESULTS: Successful brainstem implantations were performed in all patients with retrosigmoid approach. Six children gained basic audiologic functions and were able to recognize and discriminate sounds, and many could identify environmental sounds such as a doorbell and telephone ring by the third month of ABI. Improvement in mean performance on Meaningful Auditory Integration Scale is apparent for all ABI children. Improvement in Meaningful Use of Speech Scale scores in 2 patients, demonstrating that the child using its own voice for speech performance, was observed between the baseline and 12th month. First, 5 children were able to identify Ling's 6 sound by the end of 2 to 6 months, and 2 of them also started to identify words due to their pattern differences and multisyllabic word identification by 6 to 9 months. Two children with Attention Deficit Hyperactivity Disorder have made slower progress than the other children with ABIs. CONCLUSION: Our preliminary results show that there is adequate contribution of brainstem implants in the development of auditory-verbal skills. Additional handicaps slow the progress of the prelingually deaf children
