Hyperplastic polyps are often multiple and by far the most frequent lesions among gastric polyps, contributing for about 90% of the polypoid lesions observed in the stomach. However, hyperplastic gastric polyposis is rare and was not exactly evaluated for natural course. These lesions are considered reactive and not genetically determined conditions. So it has been claimed that the hyperplastic polyps and hyperplastic polyposis are non-neoplastic lesions that result from regenerative hyperplastic reaction to inflammation and erosion. Recently we experienced a hyperplastic gastric polyposis with morphological changes during short follow-up period and reported herein.

We used single photon emission computed tomography (SPECT) with technetium-99m hexamethylpropylene amine oxime (99mTc-HM-PAO) in 14 studies on 6 patients with delayed neurologic sequelae from carbon monoxide (CO) poisoning to determine whether any changes in cerebral blood flow could be correlated with clinical or computed tomographic evidence of delayed deficits. Among the six initial CT brain scans, two showed low density of both basal ganglia and two showed decreased density of the cerebral white matter. There was no correlation between the clinical outcome and the findings of the follow-up CT brain scans. Of the two SPECTS with 99mTc-HM-PAO performed during acute anoxic insult, one showed focal hypoperfusion which appeared 20 days prior to the onset of delayed neurologic sequelae after CO poisoning. Seven SPECTs in the six patients performing the delayed phase showed diffuse patched patterns of hypoperfusion which improved on follow-up images. There was good correlation between the clinical outcome and the findings of the 99mTc-HM-PAO SPECT. In preliminary conclusion, 9Tc-HM-PAO brain SPECT can be used for predicting or evaluating the outcome of delayed neurologic sequelae after CO poisoning. Cerebral vascular changes may be the possible cause of hypoperfusion in patients with CO poisoning.

Strokes in young adults are relatively uncommon. It usually occurs in the middle-aged and elderly. Only 3-8% of all strokes occurred in patients aged 15-45 years. But despite of the small percentage of occurance. It had more various and diverse possible causes than strokes in elderly. We evaluated l63 patients aged 15-45 years who were admitted to our hospital during 1985-1989 under diagnosis of cerebral infarction. Intracerebral hemorrhage. And subarachnoid hemorrhage. This group comprised 14.4% of all ages admitted for strokes. Cerebral infarction was diagnosed in 52 patients:the possible causes were hypertension and diabetes mellitus, cardiac embolisms, meningoencephalitis. Puerperium or oral pill, polycythemia, systemic lupus erythemtosus, and etc. Intracerebral hemorrhage was found in 71 patients ; the possible causes were hypertension 'and diabetes mellitus. Ruptured arteriovenous malformations, ruptured aneurysms, Moyamoya diseases, end stage renal disease, and etc. The remaining 40 patients had subarachnoid hemorrhage almost all from ruptured aneurysms. From the above results we found strokes in young adults had various possible causes, and extensive, tailored studies are needed for diagnosis.

Progressive supranuclear palsy (PSP) is a kind of chronic neurodegenerative diseases, the main clinical characteristics of which are loss of voluntary control of vertical gaze, particularly downgaze, dysarthria. Diffuse body rigidity with dystonic extension of the peck, and dementia In its earlier stages, PSP can be misdiagnosed as Parkinson's disease because of lack of awareness of the disease and symptoms and signs may not be diagnostic until the disease is advanced. About 4% of all patients with parkinson's disease turn out eventually to have progressive supranuclear palsy. We report the three cases of PSP with MRI brain scan.

A case of retrograde intussusception (acute type) of efferent limb into Braun side-to-side jejuno-jejunal anastomosis is presented. Intussusception, though infrequent, is well recognized complication after gastric surgery. Patient was 50 year old man who was admitted with epigastric pain and abdominal mass for 6 hours. Patient had a history of total gastrectomy 2 years before admission due to stage II gastric cancer. Seven hours after admission, hematemesis developed. Emergency fiberopticgastroscopy revealed type 4 jejunogastric intussusception. Segmental resection with end-to-end reanastomosis was performed.

Two hundred and four patients with Parkinson's disease initially treated wth a combination of levodopa and carbidopa ( Sinement 25-250 ) and / or anticholinergic drugs. All patients responded initially to drug. Sixteen patients(7.8%) had 20 acute central nervous system side effects: 8, dyskinesia: 6, visual hallucination:5, psychosis: and 1, akathisia. The response to treatment usually was stable for the first one and a half to four years of drug therapy. Subsequently, over 50 percent of patients had therapeutic failure among 82 patients with long term drug therapy, fourteen(l7.0%) had 18 side effects: 8, on-off phenomenon: 4. Morning dystonia: 3, dyskinesia:and 3, simultaneous dyskinesia with parkinsonism. None had diphasic dyskinesia or myoclonus. The prognosis of the demented parkinsonian was relatively poor. Two patients died due to pneumonia and ovarian carcinoma.

Infection with cytomegalovirus(CMV) during adult life was first recognized in debilitated patients with compromised immune mechanisms, renal transplant recipients, and patients undergoing extracorporeal perfusion or transfusions. CMV infection is very rare in inmunologically normal adult. Recently CMV infection has been reported previously healthy adult, usually wth a predilection for involvement of lung, liver, spleen, hematopoietic system, or heart but central nervous system involvement is apparently rare. This report describes a previously healthy woman who had encephalitis and documented CMV infection by serologic test for CMV. So we report a case with brief review of literature.

Idiopathic orbital myositis, a subgroup of previously so called inflammatory orbital pseudotumor, occurred with acute onset periorbital pain, eyelid swelling, proptosis, and ophthalmoplegia. Currently many pathologist and ophthalmologist agreed the term pseudotumor or Tolosa-Hunt syndrome and They classified some cases as characterized histologic and computerized tomographic evidence of inflammation of extraocular muscles, good responsiveness to prednisone, remission and exacerbation, with recurrence, but generally benign condition. The possibility of idiopathic orbital myositis being an immune-mediated process has been discussed. Some believe many of such cases have been grouped under the term Tolosa-Hunt syndrome. It is onloy in the last decade that computerized tomographic scanning has allowed precise localization of the alterations to orbital and retro-orbital strcutures. The term idopathic orbital myositis is precise insofar as it indicates the structures primarily involved ocular muscles. We report a case of idiopathic orbital myositis withr review of literatures.

This is a case report of 32 year-old man with adynamia episodica hereditaria. Adynamia episodica hereditaria is a rare disorder characterized by episodic atacks of muscle weakness occuring in association with an increased serum concentration of potassium. The disorder is usually inherited as autosomal dominant trait and myotonia can be seen in much of the cases. And it is uncertain whether adynamia episodica hereditaria and paramyotonia congenita are variable manifestations of the same disease or not. We now reporta case of adynamia episodica hereditaria with myotonia with the special reference to pathophysiology of paralysis and myotonic symptom.

Between 1985and 1987, 31 patients with sporadic olivopontocerebellar atrophy (SOPCA) and 3 patients with familial olivopontocerebellar atrophy (FOPCA) were examined in the Neurologic Clinic of Yongdong Severance Hospital. The incidence of the disease among our neurology clinic patients was 0.9% and 3.4% of those patients were admitted. Seventeen of them were men and seventeen women, and their ages of onset ranged from 16 to 75 years (mean, 48.2 years). In comparison with SOPCA, the disease began earlier in FOPCA (mean age, 51.0 VS 19.3 years), but there were no other differences in clinical feature of the disease. Four patients had parkinsonism, one dementia, and one ophthalmoplegia. None presented spinal involvement or abnormal movements. Eight had a coexisting disease; 3, ch(03)nic alcoholism; 2, hypertension; 2, diabetes mellitus; and 1, malignant neoplasm.
