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.

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.

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.

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.

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.

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.

Both interictal Tc-99m hexamethyl-propyleneamine oxime single photon emission computed tomography (HM-PAO SPECT) brain scintigraphy was done in a patient with the syndrome of chronic encephalitis and epilepsy. The low density area in the temporo-occipital lobe on brain CT scan revealed decreased radioactivity during interictal state and it was reversed to increased radioactivity during ictal state on HM-PAO SPECT brain imaging. In authors' opinion, ictal and interictal Tc-99m HM-PAO SPECT brain scintigraphy could be a safe and convincing study for Searching epileptogenic foci.

Pathophysiology of acute carbon monoxide poisoning is not clear. It is generally accepted that hypoxic and/or anoxic insult is very significant role in the pathophysiology of acute acrbon monoxide poisoning, but many arguments are documented especially focal hypoxia or metabalic acidosis within brain parenchyme. In sofar such a focal change seems to be largely depend upon focal change of neuroendocrine substances including B-endorphin. Also B-endorphin is known to be responsble to the pathogenesis of cerebral ischemia. Though the possible relationship between the alteration of level of B-endorphin and hypoxia, it is seldom to pay attention to the role of B-endorphin in carbon monoxide intoxication. We measured plasma B-endorphin in acute carbon monoxide intoxication and compared with the value of control group. There was no difference between control group and acute carbon monoxide poisoning group, the possible role of B-endorphin in acute carbon monoxide poisoning should not be excluded. We suggest the more comprehensive and newly programmed study seems to need for clarifying the possible role of B-endorphin in acute carbon monoxide poisoning.
