[Obstetric complications associated with DIC. Importance of D-dimer in the diagnosis and treatment. A clinical case].

The case of a 32-year old woman with 36-week pregnancy presented at hospital because of spontaneous vaginal bleeding, anemia and mild hypotension is reported. Fetal mors in utero, abruptio placentae and diffuse intravascular coagulation were diagnosed. The patient subsequently underwent cesarean section and large retroplacental hematoma was removed and obviously fetum. The DIC was easily controlled by means of recently introduced method of determination of fibrin D-dimer.

[Comparison of 2 techniques of anesthesia induction in modern closed-circuit anesthesia].

The application of low flow anesthesia goes back already for more than 65 years when Ralph Waters introduced and applied cyclopropane with a very simple canister technique. The guide-lines for the clinical use of the closed circuit anesthesia were published in Chicago and Los Angeles by Professor Lin and Professor Lowe 15 years ago. We examined and followed these procedures on a modern anesthesia machine and easily achieved a good clinical performance. Our results were consistent with the modern anesthesia standard in closed circuit t.i.: economical benefits, environment savage of waste gases, heat production and humidification and last but not least in both techniques a quick anesthesia plane on 10-12 minutes that was consistent with theoretical considerations.

[The use of intravenous nifedipine for the treatment of severe hypertensive crisis. A clinical case].

Nifedipine is a calcium channel antagonist. Hypertensive crisis during anaesthesia may be elicited during the induction period or by the surgical manipulating of intrapelvic viscera. We report a case in which nifedipine given intravenously (currently an investigational dosage form) was effective in controlling a severe hypertensive crisis at dose averaging 3.4 mcg/kg/min initially and half as much for maintenance. Arterial pressure was controlled as quickly as with nitroprusside, but with no change in heart rate or cardiac output and without other untoward effects during anaesthesia.

[Hydrothorax as a complication of subclavian vein catheterization. Pathogenetic mechanism and description of a clinical case].

We report a case of possible detouring and malfunctioning of the left subclavian catheter in the homolateral internal mammary vein or of perforation form its tip of the wall of the left innominate vein. The tip of the catheter was rigid and sharp, may be the contractions of the heart or turbulent flow impinged it against the vein wall and have enhanced the perforation. The result was a hydrothorax that allowed a severe cardiac simile tamponed syndrome. The pathophysiology was also discussed.

[Poisoning with shoe dye. A clinical case].

The paper reports the case of a young male which was severely poisoned by anilyne shoe black. After a few hours, he was in a semicomatose state, accompanied by "very dark" arterial blood gases with oxygen tension in excess of 100 mmHg. Following the administration of intravenous methylene blue (2 mg/kg), methemoglobin was reduced to hemoglobin and the level of consciousness immediately improved.

[Hemofiltration and dialysis in a case of rhabdomyolysis].

The effect of CAVDH was evaluated in a patient with rhabdomyolysis due to extreme low temperature and also to carbon monoxide poisoning. Since renal failure im myoglobinuria has a relatively good prognosis, we recommend in this case the use of a soft technique such as continuous arteriovenous hemofiltration with dialysis.

[Screening of early color vision loss in diabetic patients].

Colour vision defects have been claimed to appear in diabetes before any retinopathy is visible. In the present study diabetic patients and non diabetic control subjects were screened with two different colour vision tests which include both red-green and blue-yellow parts, and are suitable for quantitative analysis of scores. The Lanthony 40 Hue test and the Tokyo Medical College--T.M.C. tables were used to assess colour vision in 106 diabetic (50 insulin dependent and 56 non insulin dependent) patients and in 99 non diabetic control subjects. Diabetic patients without visible retinopathy, familiar colour vision defects and/or lens changes, had significantly higher scores than control subjects in both eyes. The differences were more evident in non insulin dependent patients. Statistical analysis showed that early loss of colour vision was correlated with age and duration of diabetes for older patients, while correlation with glycosylated hemoglobin was moderately positive only for younger patients. Both tests (especially the Lanthony 40 Hue) resulted to be highly specific and could be used for the clinical study of colour vision losses in diabetic patients.

Further observations on the extramacular chromatic mechanisms.

Monochromatic targets presented at 30 degrees excentricity on orange, magenta and blue backgrouds are used. A small monochromatic light, 476 nm on orange, 551 nm on magenta and 621 nm on blue, is flashed at 3 cps-1 on the centre of the targets. The size of the targets is varied and their luminance adjusted using neutral filters until the flashing light is just not visible. This method allows the study of chromatic mechanism sensitivity and of retinal interactions (summation and inhibition). Some observations in normal as well as in pathological conditions are presented.

Acquired 'tritan' deficiencies in macular pathology.

14 patients with maculopathy (18 eyes affected, 10 eyes clinically normal) were examined using the HRR plates, the Farnsworth F2 (tritan) plate, the Farnsworth panel D15 test, the Nagel anomaloscope (model I) and on a 'blue-green' equation for 2 degrees and 11 degrees fields on the Moreland anomaloscope. The correlation of tritan-like responses to each test and the differences between the 2 degrees and 11 degrees equations are discussed.
