Sectrofluorimetric micromethod for determining riboflavin in the blood of new-born babies and their mothers.

A microdetermination of riboflavin on the blood of new-born babies and their mothers was developed on the basis of hydrolysis of the blood in a trichloroacetic acid medium, separation of riboflavin and FMN on a Florisil column and measurement of the content spectrofluorimetrically by the standard addition method after elution with collidine buffer. The sensitivity of the method is 0.01 microgram/ml, the blood sample size 0.5--1.0 ml. The normal level in new-born babies in the first day of life was found to have an average value of 17.1+/-2.4 microgram/100 ml, in women 14.2+/-2.5 microgram/100 ml; the contents in cord blood and maternal vein blood were also determined.

Systemic angioendotheliomatosis (author's transl).

Two cases of systemic angioendotheliomatosis are reported. The first patient was a 20-year-old pregnant Negro woman from Ghana; the diagnosis was established in the biopsy of the skin lesions; the follow up of the patient is unknown. The second patient, a 70-year-old man, presented repeated but transitory loss of sight and speech, later on associated with unconsciousness and convulsions. He died of severe epileptic status two months after the onset of the symptoms. Systemic angioendotheliomatosis was found in the brain as well as in other organs and tissues.

[Vaginal reflux during miction-cystourethrography in girls (author's transl)].

The cases of 57 girls with reflux of radioopaque iodin solution into the vagina during mictioncystourethrography are reported. In 52.6% (30 cases) no signs of anomalies of the urinary tract or of pyelonephritis were found. For this group of 30 girls pyuria (leucocyturia) was typical (in 86.6%). In contrast, a urinarty-tract infection was found only in a few cases (16.6%). The authors discuss the clinical importance of vaginal reflux and its role in the pathogenesis of urinary-tract infections.

Angina pectoris and middle-aged man.

The incidence of some risk factors of ischaemic heart disease in men aged 40-55 years is compared with the presence and absence of angina pectoris (AP). Patients with positive AP had significantly higher values of the blood pressure, serum cholesterol level, and ponderal index. The frequency of probably pathological and possibly ischaemic changes was likewise significantly higher in the group with AP. Intermittent claudication was more frequent in this group as well. No significant difference in consumption of cigarettes was found between the two groups.

[Experience with a technic using basic fuchsin for the demonstration of early myocardial ischemia].

A series of 156 patients dying suddenly and unexpectedly was analysed with respect to the occurrence of fibres staining with basic fuchsin with the method of Lie et al. (6). The findings were correlated with the cause of death, coronary sclerosis and heart weight. Positive staining was revealed in the form of contraction bands or perinuclear segments. No statistically significant correlation was demonstrated between the occurrence of positive fibres on the one hand and regressive myocardial changes due to coronary and extracoronary insufficiency or other causes on the other hand.
