In the past years we have been applying semantic ATN-grammars as introduced by Brown & Burton (1974) to natural language question-answering tasks (e.g. a LISP-Tutor [Barth, 1977], s question-answering system about the micro-world of soccer [Rathke & Sonntag, 1979]). We found that semantic grammars execute efficiently, but become large very quickly even with moderate domains of discourse. We the...
It is characteristic of the early development of the vertebrate animals that the embryo should be formed largely as a result of successive displacements of the cell population created during and after cleavage. Of these the first bring the endoderm and the mesoderm into what are effectively their definitive positions by paths that vary somewhat from one vertebrate to another. They are followed ...
PURPOSE This study evaluated the clinical manifestations of and risk factors for pituitary insufficiency in children and adolescents with Rathke's cleft cysts. METHODS Forty-four patients with Rathke's cleft cysts younger than 19 years who visited Seoul National University Children's Hospital between January 1995 and September 2009 were enrolled. Rathke's cleft cysts were confirmed histologic...
Arachnoid cysts (ACs), particularly suprasellar cysts, cause a wide spectrum of endocrine disorders. Herein, we report two patients diagnosed with an extensive AC in the middle cranial fossa while being investigated for etiologies of precocious puberty and short stature. One of them required surgery due to his pubertal disorders associated with compression effects of cyst. After surgery, his pu...
OBJECTIVE To determine the pathogenesis and characteristics and to assess the long-term effectiveness of polymethylmethacry late (PMMA) vertebroplasty treatment in patients with intravertebral cleft (IVC) in osteoporotic compression fractures. METHODS A retrospective analysis of radiological and clinical parameters was performed on 388 patients who underwent percutaneous vertebroplasty or kyp...
BACKGROUND Patients with brain tumours have a high risk of water and electrolyte disorders (WED). Postsurgery diabetes insipidus (DI) may be transient or permanent, the syndrome of inappropriate antidiuretic hormone secretion (SIADH) and cerebral salt-wasting syndrome (CSWS) are usually transient. METHODS Retrospective study, including patients with suprasellar tumours, treated at Hôpital Nec...
Approximately 9 to 15% arachnoid cysts occur in the sellar or suprasellar region. The optimal management of symptomatic suprasellar cysts continues to pose a challenge to neurosurgeons. This case report describes a patient with a suprasellar arachnoid cyst who presented at the age of 3 and was followed for 20 years after cystoventriculostomy. A girl was referred to neurosurgery department by a ...
A 41-year-old man was admitted to our hospital because of general fatigue, sexual debility and finger stiffness. Endocrinological examinations revealed that he had panhypopituitarism, resulting in secondary adrenal insufficiency, hypothyroidism and gonadal failure. Computed tomography (CT) of the head demonstrated a low density intrasellar mass, while brain magnetic resonance imaging (MRI) show...
A 68-year-old woman was admitted to determine the pathogenesis of weight loss and polyuria. Physical findings on admission showed BMI of 20.9, blood pressure of 147/69 mmHg, and that she had ciliac, axillar and pubic hair loss. Laboratory findings showed that plasma adrenocorticotropic hormone (ACTH) was 4.6 pg/mL with serum cortisol of 1.2 µg/dL. Serum luteinizing hormone (LH) and follicle-sti...
