Feasibility and neurologic complications accompanying spinal anesthesia with variable specific gravities were examined in 56 lumbar disc operation from March 1977 to October 1978. Patients' age ranged from 21 to 36 years with 54 cases of males and 2 females. On myelography, lateral and partial blocks were observed in 50 cases and total blocks in 6 cases. These cases were classified depending on the specific gravity and local anesthetics as follows: .Isobaric group: a) 1% tetracain solution, ampule, mixed with C.S.F., 20 cases. b) tetracaine powder with C.S.F., 11 cases. c) 10% procaine solution with C.S.F., 9 cases. .Hyperbaric group: 1% tetracaine solution with 10% dextrose in water, 10 cases. . Hypobaric group: tetracaine powder with water, 6 cases. Under isobaric, hyperbaric and hypobaric spinal anesthesia, good to excellent results were obtained in 90, 90 and 16.6% respectively. More than 10% of systolic blood pressure fall after block was seen in 15, 90 and 16.6% respectively. No neurologic sequalae were observed. Isobaric spinal anesthesia with tetracaine solution is indicated as safer for recently herniated lumbar disc operations.

A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.

The authors studied the diagnostic usefulness of the Topographic analysis of EEG, using Topography ststem 700 (San-ei), in evaluation of supratentorial focal cerebral lesions of 27 patients with various etiology, comparing with visual anslysis of EEG. Focal cerebral lesions, which were proven with brain C-T, were 11 cases of cerebral infarction, 6 of intracranial hematoma, 6 of cerebral gliolysis and 4 of others. The topography system displays the spatial distribution of activity in the classic delta, theta, alpha and beta frequency and computed mapping of EEG displays equipotential maps of square of roots of power spectra over each frequency band. For visual analysis of slow waves and background activity changes, Mayo classification system of EEG abnormality was used and for visual evaluation of topographic display, above system was also applied with some modification in order to compare with the data of visual analysis of conventional EEG. The results of the study were as follows; 1. While visual analysis of conventional anlysis of EEGs showed abnormality only in 13 cases (48.1%) of 27, topographic analysis showed abnormality in 22 cases (81.5%). Topographic analysis was more sensitive than than visual analysis of the EEG and topographic analysis was thought to be more sensitive in assessment of local slow waves as well as minor changes, especially slight asymmetry, of background EEG activity. 2. Topographic analysis showed higher concor dance rate (55.6%) to the brain C-T finding in lateralization of supratentorial focal cerbral lesion than that (44.4%) of visual analysis of the conventional EEG.

Pigmented Paravenous Retinochoroidal Atrophy(PPRCA) is a type of pigmentary retinopathy that affects mostly both eyes symmetrically without inheritance. The PPRCA occurs in both progressive and non-progressive forms, but most cases are non-progressive forms. The fundus appearance of PPRCA is characteristic, with peripapillary pigmentary change as well as areas of retinochoroidal atrophy adjacent to the perivenular pigmentary change. The authors have studied a case of PPRCA which was diagnosed through the characteristic fundus appearance and other ophthalmological examinations.

Pseudothrombocytopenia is an in vitro phenomenon usually associated with anticoagulant (ethylene diaminetetraacetic acid, EDTA)-dependent IgG platelet agglutinins. Two cases of pseudothrombocytopenia due to EDTA-independent agglutinins are reported. The fingerstick blood smear showed platelet clumping as well as EDTA, citrate and heparin samples. In a case with malaria, serum IgM was 985 mg/dL and serum protein immunofixation demonstrated an additional IgM band which disappeared together with platelet clumping a month later. The increased immunoglobulin (especially, IgM) appeared to be associated with platelet agglutinin. Another case had cold reactive agglutinin because the electronic platelet counts were dependent on temperature. These cases illustrate that pseudothrombocytopenia may be caused by more than one type of agglutinin and can be confirmed by using a direct fingerstick, keeping the sample warm, or drawing the blood into another anticoagulant.

We studied 249 patients with risk factors of retinopathy of prematurity and the results were as follows: 1. Among 249 patients, retinopathy of prematurity(ROP) developed in 36 patients(14.5%). 19 patients(528%) were stage 1, 4(11.1%) patients were stage 2, 11 patients(30.6%) were stage 3, 2 patients(56%) were stage 4 and there was no stage 5 ROP patient. 2. In gestational age, there was not statistically significant difference between normal lnfants and under-prethreshold stage group, but there were statistically significant differences between normal or under-pretheshold stage group and pretheshold or theshold stage group and was not stastically significant difference between prethreshold stage and threshold stage. 3. In birth weight, there was statistically significant difference between normal group and under-prethreshold stage group and also be statistically significant differences between normal or under-prethreshold stage and pretheshold or threshold stage group but there was not statistically significant difference between prethreshold stage and threshold stge. 4. In duration of oxygen therapy, there were no statistically Significant differences among each group.
