[Diagnosis of vascular impotence: comparison of Doppler sonography and arteriography]. / Diagnostik der vaskulären Impotenz: Vergleich von Doppler-Sonographie und Arteriographie.

The use of Doppler ultrasonography to examine penile arteries represents an important step in the multidisciplinary evaluation of erectile dysfunction. This noninvasive method for demonstrating the presence of arterial lesions was found to have a sensitivity of 92.6% and an accuracy of 90% when compared with selective arteriography. The necessity of performing selective arteriography can be markedly reduced in cases of erectile dysfunction by investigations using Doppler ultrasonography.

[Corpus cavernosum autoinjection therapy: initial experiences in erectile dysfunction]. / Schwellkörper-Autoinjektionstherapie (SKAT): erste Erfahrungen bei erektiler Dysfunktion.

The cause of erectile dysfunction was evaluated by a multidisciplinary approach in 120 impotent patients. Out of these, the CCAT was proposed to 20 patients with vasculogenic erectile dysfunction, 19 of them accepted this therapy. The dosage of phentolamine mesylate-papaverin hydrochloride injection required was determined in each patient individually. Usually we injected initially 1 cc in one corpus cavernosum. Eighteen patients followed the regimen successfully at home. In 2 patients prolonged erections were observed, which were successfully relieved by simple corpus puncture, however, discontinuation of therapy was not necessary. CCAT failed in 1/19 patients with a severe venous leak. Follow up was carried out weekly.

[Selective arteriography of the internal pudendal artery in posttraumatic erectile dysfunction]. / Selektive Arteriographie der A. pudenda interna bei posttraumatischer erektiler Dysfunktion.

102 patients with erectile dysfunction were evaluated by a multidisciplinary approach including measurement of the bulbocavernous reflex (BCR)-latency, cystometry, dynamic cavernosography and bilateral selective arteriography of the pudendal arteries. Seven patients had a posttraumatic source of their erectile failure. Three patients showed a mixed neurogenic-arteriogenic aetiology of erectile dysfunction, two patients had evidence of isolated arterial damage, one patient had a venous and one an isolated neurogenic cause of erectile dysfunction. The passage of pudendal-penile vessels and nerves through the urogenital diaphragm is the most vulnerable portion of its way through the pelvis. Ruptures of the prostatomembranous urethra are frequently accompanied by injury to the pudendal-penile vessels and nerves, thus causing erectile dysfunction.

Neuropsychological and neuroendocrinological disturbances associated with extracerebral cysts of the anterior and middle cranial fossa.

In ten adult patients various clinical signs and symptoms led to the diagnosis of an arachnoid cyst in the anterior and middle cranial fossa. In this study a functional relationship between these cysts and disturbances of higher cognitive processes is described. In addition, neuroendocrinological impairment were caused by arachnoid cysts reaching into the suprasellar cistern. Considering the short medical history of our patients we presumed the disturbances not to be primary, but rather secondary, caused by an expansion of the cysts' volume.

[Investigation of the suitability of efficiency tests in evaluating endogenous depression (author's transl)]. / Untersuchungen zur Eignung von Leistungsverfahren für die Messung von Schweregraden endogener Depressionen.

Self-evaluation procedures are usually used to assess the severity of endogenous depression. In this respect, efficiency tests have hitherto been scarcely considered. A literary survey and our own empirical investigations suggest that self-evaluation procedures should mainly be used in mild and moderate endogenous depressions, and that these procedures give false results in severe and very severe depressions. Efficiency procedures seem not to differentiate well between 'normality' and 'mild depression,' but they become more reliable and valid for depressions of increasing severity. Self-evaluation and efficiency procedures should therefore not be substituted for each other; they should complement each other.

[Performance of medical students on the short syndrome-test. On the recognition of functional psychoses in young highly intelligent adults]. / Leistungen von Medizin-Studenten im Syndrom-Kurztest. Zur Erkennung von Funktionspsychosen bei jungen, sehr intelligenten Erwachsenen.

Erzigkeit's accelerated syndrome test is used to determine the severity of functional psychoses. This test, by which the proficiency level of a subject may be ascertained, should be evaluated in dependence upon the subject's age and general level of intelligence. To correct for these quantities, the accelerated syndrome test includes combined standards for four age and three IQ levels (12 tables of standards). The quality of correction should be empirically verified here. A sample of sixty-three medical students (this sample was characterized by a very high degree of homogeneity in that the students were of the same age and also had the same IQ's) were used to show that the standardization of age and IQ in the accelerated syndrome test allows functional psychoses to be far more readily recognized than when no consideration is given to these variables. Classification by degrees of disorder should also be much more convincing than without the use of differential standardization.
