[Diabetic angiopathy. Proteinuria as an initial symptom].

Follow up studies in 19 diabetic patients with manifestation in the youth. Proteinurie within few years; later on nephropathy: 7 cases with glomerulosclerosis, 8 with arteriolosclerosis, 3 with pyelonephritis and 1 with chronic glomerulonephritis. In all cases retinopathy, very often coronarsclerosis, seldom peripheral and cerebral sclerosis. 14 patients died, mostly in young age in consequence of nephropathy. Proteinurie is a malignant symptom of diabetic angiopathy; in contrast to the retinopathy.

[Proliferative retinopathy in growth-onset diabetes and in maturity-onset diabetes (author's transl)].

95 diabetics with proliferative retinopathy were divided into two groups according to the type of diabetes, Group I consisting of 25 cases of growth-onset diabetes and Group II of 70 cases with maturity-onset diabetes. A distinct tendency was observed in Group II cases towards a shorter duration of diabetes prior to the manifestation of retinopathy, i.e. less than ten years. The pre-proliferative phase of the retinopathy is similar in duration and manifestation in both groups. There is no difference in the ophthalmoscopic findings or development of proliferative retinopathy either, except that its course is more aggressive in Group I, in contrast to the slower course with longer remissions seen in Group II cases. Thus, the basic characteristics of proliferative retinopathy appear to be independent of the form of diabetes, in keeping with the concept of diabetes mellitus as a single disease entity.

[Changes of circulation, blood gases, acid-base-and metabolism during neurolept-analgesia with and without beta-receptor blockers in electro coagulation of Gasser's ganglion (author's transl)].

The cardiovascular, blood gas, acid-base and metabolic changes occurring during operative stress were studied in 10 elderly, metabolically healthy patients, suffering from idiopathic trigeminal neuralgia, who underwent electrocoagulation of the gasserian ganglion under neuroleptanalgesia. In a group of 12 patients undergoing the same operative procedure and anesthesthetic management, we investigated the effects of administration of a beta blocking agent on these parameters. Intraoperative rises of blood pressure and tachycardia were prevented by intravenous administration of 0.4 mg Pindolol (Visken), whereas increases in the blood glucose levels at the end of the operation were the same. The increase of glycerol, free fatty acids and ketone bodies was markedly reduced after pretreatment with the beta blocker compared with the controlgroup. In the patients without beta blocker treatment pH and standard bicarbonate at the end of the operation were lower as the result of the stimulation of ketogenesis.

[Hormonal changes during electrocoagulation of the Gasserian ganglion under neuroleptanalgesia and the effects of administration of a beta blocking agent (author's transl)].

Hormonal changes, occurring during electrocoagulation of the Gasserian ganglion under neuroleptanalgesia, and the effects of intravenous administration of pindolol 0.4 mg on these changes were investigated in two groups of 10 and 12 patients of advanced age. At the end of the operation there were marked increases of the concentrations of catecholamines, a rise of the plasma cortisol and a fall of the serum insulin. The administration of the beta-adrenergic blocking agent did not induce any statistically significant changes of the determined hormones compared to the control group.

[Diabetic retinopathy: onset in pregnancy (author's transl)].

Retinopathy appeared during pregnancy, mostly in the last trimester, in 20 female diabetics. In some cases the retinopathy reappeared during the subsequent pregnancy, whilst in other cases it skipped one or two pregnancies. The retinopathy was mostly of a mild form and, in about half the cases, disappeared spontaneously post partum. In the remaining cases it remained stationary or subsided to a great extent, but certainly did not become progressive. Forms of angiopathy other than retinopathy remained in the background. No toxicoses, and no other complications were seen during pregnancy. Hence, pregnancy promotes or accelerates the onset of diabetic retinopathy, its influence on the course of the disease being favourable rather than harmful.

[Retinopathy and angiopathy in diabetes of fifty to sixty years duration (author's transl)].

A report is given on ten (seven female, three male) diabetis with uncommonly long duration of the disease. Diabetes had become manifest at an early age (mostly childhood) and, then, had continued for a period of fifty to sixty-one years. Eight patients suffer from retinopathy, two are free from it. Only three cases show nephropathy of moderate development and inconspicuous progression. Coronary sclerosis, peripheral sclerosis, and neuropathy recede with time. There is a surprising discrepancy of findings concerning retinopathy - on the one hand: simple retinopathy tending to spontaneous regression; on the other hand: malignant proliferating retinopathy. Uncommon also is the tarrying behaviour of nephropathy.

[Diabetes mellitus: puberty and angiopathy (author's transl)].

It is inferred from a study of 140 cases of diabetes mellitus commencing between the ages of 10 and 17 that puberty causes the premative and accelorated appearance of angiopathy. The characteristic course of the angiopathy is not affected by puberty and does not necessarily persue an absolutely malignant form. It is genetically pre-determined and undergoes only insignificant enviornmental modifications subsequently.

[Spontaneous regression of diabetic retinopathy (author's transl)].

A report is given on seventeen cases of spontaneous regression of diabetic retinopathy. The diabetes became manifest, without exception, at an early age, particularly in childhood. Regression came on slowly and inconspicuously, retinopathy disappearing completely in two thirds of the cases. Of the other forms of diabetic angiopathy only arterial hypertension was found. No case of specific nephropathy, but frequently chronic infections of the urinary tract, and intermittent proteinuria were observed.

The results of "exercise therapy in coronary prone individuals and coronary patients".

The authors followed for at least two years 483 patients (430 coronary prone patients and 53 with proved coronary heart disease), to determine whether physical training could decrease coronary risk factors and improve exercise tolerance in the trained group as compared with the conventionally treated group (way of life, diet, drugs). There was no significant difference among the two groups for blood lipid profile, blood pressure (at rest and during exercise), functional capacity and mortality. In the authors' opinion this could be explained by the inadequate training program (45 minutes twice a week) and by a possible overlapping of the groups.

[Ulstrasonic monitoring for early diagnosis of air embolism during neurosurgical procedures (author's transl)].

The sitting position of the patient offers many advantages to the neurosurgeon for operations at the posterior fossa, the upper cervical region, the Gasserian ganglion and the retroganglionic trigeminal root. Air embolism is however one of the greatest dangers during operations in this position. Air emboli occur more frequently than it is generally recognized. Most monitoring systems indicate the entrance of air at a late stage only. But early diagnosis and immediate therapy are of utmost importance. The use of an ultrasonic monitoring device for early diagnosis and the preoperative insertion of a right artrial catheter for immediate aspiration of the air are recommended.

[The retinopathy of the childhood diabetic (author's transl)].

From investigations of 141 patients, diabetic since childhood, diabetic retinopathy (angiopathy), shows strikingly contrasting forms of progress: (a) thoroughly benign (retinopathia simplex; partly regressive); (b) malign (retinopathia proliferans and glomerulosclerosis). The tendency to progression of diabetic retino- and angiopathy appears to be hereditarily determined and is modified, later, only to a certain extent by environmental factors.

[Manifestation of diabetes in the first to third year of life. Later fates of 43 patients (author's transl)].

Life expectancy of diabetics since early childhood is differently judged. Out of 43 own patients with diabetes started between the first and third year of life, no less than 33 have passed their twentieth year of life; 16 patients are aged between 25 and 46 years; one woman patient lived to the age of 64! In all cases the duration of diabetes is more than 10 years, in 26 cases 20 years or more. In 24 cases angiopathy developed chiefly in the form of retinopathy, nephroapthy and arterial hypertension (none in 19 cases). 7 patients died of uraemia. While there is hardly any difference between the two groups (with or without angiopathy) as far as duration and quality of diabetes-control are concerned, in the angiopathy-group hereditary taint clearly prevails. The early beginning of diabetes does not at all represent an absolutely unfavourable symptom, rather the reverse (O. Imerslund).

[Manifestation of diabetes (author's transl)].

Material of research: 350 cases of diabetes mellitus. The time between the manifestation of diabetes mellitus and the onset of retinopathy is reduced in two cases: with diabetes manifesting itself (a) at the age of puberty, (b) after the age of fifty. The retinopathy appears as "retinopathia simplex" (in all its different subvarieties) and as "retinopathia proliferans". Out investigation showed a gradual decrease in the benign forms of the retinopathia simplex with advancing years--from twenty to sixty--of diabetic manifestation, with retinopathia proliferans simultaneously gaining ground. With diabetes manifesting from sixty on, retinopathia proliferans dwindles to insignificance; there remains an indefinite form of retinopathia simplex.
