1/5. Pituitary adenoma associated with gigantism and hyperprolactinemia.An 11-year-old girl presented with excessive growth, headache, left visual loss and seizures. Her growth hormone (GH) and prolactin (PRL) levels were high and magnetic resonance imaging findings showed an invasive macroadenoma. Gross total tumor removal was performed and then radiotherapy and medical therapy were given. During the follow-up, she developed ACTH deficiency, secondary hypothyroidism and hypogonadism requiring replacement therapy. It is still unclear whether the biological characteristics of GH- and PRL-secreting tumors are different in children from those in adults. More data are needed before a definitive conclusion can be established.- - - - - - - - - - ranking = 1keywords = headache (Clic here for more details about this article) |
2/5. CT diagnosis of macrodystrophia lipomatosa. A case report.Radiographs and CT scans of a 45-year-old male with progressive enlargement of his right upper limb and shoulder are presented. Extensive soft-tissue hypertrophy with linear radiolucent bands (fat) limited to the lateral aspect of the limb were seen. exostoses-like bony overgrowth were also seen along interphalangeal joints. At CT, hypertrophic adipose tissue intermingling with muscle fibers was demonstrated, a diagnostic finding distinguishing the lesion from plexiform neurofibrolipomatosis, Klippel-Trenaunay syndrome and other angiomatous lesions.- - - - - - - - - - ranking = 0.05355430389909keywords = upper (Clic here for more details about this article) |
3/5. Long-term effects of octreotide on pituitary gigantism: its analgesic action on cluster headache.We report the case of 19-year-old man with pituitary gigantism due to growth hormone-producing pituitary macroadenoma. The patient complained of recurrent headache and excessive growth spurt since age 15. octreotide administration was initiated following transsphenoidal pituitary adenomectomy. octreotide injection for 4 years efficaciously reduced the size of remnant adenoma as well as serum growth hormone levels. Notably, octreotide exhibited a potent analgesic effect on his intractable cluster headache that has continued even after reduction of the adenoma volume. The analgesic effect lasted 2 to 6 hours after each injection and no tachyphylaxis to octreotide appeared during 4-year treatment. To characterize the headache and the pain intensity, analgesic drugs including octreotide, lidocaine, morphine and thiopental were tested using a visual analogue scale (VAS) evaluation, with the result that octreotide exhibited a prompt and complete disappearance of the headache. Headache relief was in part reproduced by morphine injection (56% reduction) but not by lidocaine or thiopental. The present case suggests that the intractable headache associated with pituitary gigantism is possibly related to the endogenous opioid system. Thus, the headache control by octreotide is clinically helpful for continuation of the self-injection regimen.- - - - - - - - - - ranking = 10keywords = headache (Clic here for more details about this article) |
4/5. Anaesthesia for transsphenoidal surgery in a patient with extreme gigantism.The management of anaesthesia for transsphenoidal removal of a pituitary adenoma in a true pituitary giant with acromegaly is described. Problems which may be anticipated in such a patient and an approach to their management are discussed, with particular emphasis upon the need for thorough preoperative assessment of the upper airway and the provision of adequate pulmonary ventilation during anaesthesia.- - - - - - - - - - ranking = 0.05355430389909keywords = upper (Clic here for more details about this article) |
5/5. tuberous sclerosis associated with partial gigantism in a child.The authors report a case of a six-year-old boy with seizures, mental retardation and some classic features of tuberous sclerosis, i.e., cutaneous hypomelanotic macules, poliosis, cyst-like lesions of the right upper limb and cerebral calcifications. From birth he showed partial gigantism of the first two fingers of the right hand associated with an arteriovenous malformation of the ulnar artery and agenesis of the radial artery. The EEG and CT scan studies are also reported. The occurrence of two dysgenetic disorders in one patient as a manifestation of disturbed embryogenesis at a very early stage of development is discussed.- - - - - - - - - - ranking = 0.05355430389909keywords = upper (Clic here for more details about this article) |
