[Late complications in patients having undergone a gastric resection]. / K voprosu o pozdnikh oslozhneniiakh u bol'nykh, perenesshikh rezektsiiu zheludka.

A total of 37 patients who had undergone partial gastrectomy for duodenal or gastric ulcers, were investigated. The postoperative periods ranged from 5 to 28 years. All the patients were subjected to comprehensive clinical and neurologic examinations. The content of vitamin B12 and folic acid in the blood serum was studied by radioimmunoassay in 29 gastrectomized patients, hematological parameters (hemoglobin, serum iron, red blood cell morphology, proteinogram) were estimated in 19 patients. The mean content of vitamin B12 in the blood serum of patients was lower than in normal subjects. The mean level of folic acid in the blood of patients was also lower than in the control, however, this difference was insignificant. Nine patients had subnormal content of vitamin B12, eight of them showed manifest neurologic complications, such as myelopathy and polyneuropathy. Only 3 patients had subnormal content of folic acid in the blood serum. Weakly pronounced anemic syndrome was detected only in 2 out of 19 patients. The role of vitamin B12 deficiency in the development of neurologic symptoms has been considered.

[Structural changes in the brain in transient cerebral circulatory disorders detected in vivo by using computerized axial tomography and radioisotope cerebral scintigraphy]. / Strukturnye izmeneniia v mozge pri prekhodiashchikh narusheniiakh mozgovogo krovoobrashcheniia, ustanovlennykh pri zhizni s pomoshch'iu komp'iuternoi aksial'noi tomografii i radioizotopnoi mozgovoi stsintigrafii.

Computer-aided axial tomography and radioisotopic (with 99mTc) scintigraphy of the brain were used for examining 54 patients with transient cerebral circulation disturbances, the clinical manifestations of which subsides within a period of less than 24 hours. In 28% of the patients, structural changes in the brain were revealed. The computer-aided tomography appeared to be more informative for their discovery, than the radioisotopic scintigraphy. On the basis of the data obtained the patients were divided into the following three groups: a) functional, i. e. having no lifetime structural changes in the brain detected at the moment of the examination (72% of all the patients), b) ischemic-infarctic one with a minor cerebral infarctions (13.5% of the patients), and c) hemorrhagic, with small-sized hemorrhagic foci in the brain (11.5% of the patients). The existence of the latter group should be regarded as a warning of dangers entailed by routine prevention and treatment of transient cerebral circulation disturbances with antiaggregants and anticoagulants. A new classification and terminology of the clinical symptoms caused by transient cerebral circulation disturbances are offered.
