[The pathogen spectrum and its resistance behavior in children with urinary tract infections in Angola].

In 225 children (135 boys, 90 girls) suffering from clinical relevant urinary tract infection the bacterial spectrum and resistance behaviour to routinely used antibiotics were evaluated. In 65.4% of the patients a significant bacteriuria was found: E. coli (34.6%), proteus (22.3%), klebsiella (14.6%), citrobacter (9.2%), enterobacter (5.4%) and pseudomonas (5.4%). In testing a high resistance of bacterias to trimethoprim/sulfamethoxazol, ampicillin, and gentamycin was found, whereas good susceptibility was found to nitrofurantoin and nalidixin acid.

[The status of hemoglobin concentration and hematocrit in Angola children].

Hemoglobin-concentration (Hb) and hematocrit (Ht) were determined in 622 Angolean children between ages of 3 months and 13 years. The children were divided into two groups: group I (n = 530) of low social and economic state, group II (n = 92) children enjoyed good living conditions. 38.9% of all children had a Hb below 6.8mmol/l. 218 of which were part of group I, only 18 were out of group II. An extensive anemia (less than Hb 4.3mmol/l) existed in only 3% of all children. 51.7% of children were below 3 years. Between age groups of 3 months to over 10 years there was a continual rise in Hb of 17.6 +/- 6.6% (boys) and 9.5 +/- 3% (girls). Using the Ht values the percentage of anemic children was only 16.4%. It existed a relationship, especially, clearly observed in group I, between physical development and aemia frequency. Children of group I were more anemic than children of group II.

[The perceptibility of a microwave field under experimental conditions].

The development of effects caused physical environmental factors on subjective images and on behaviour of exposed persons generally presupposes the perceptibility of the factors concerned via receptors. Though there are no indications regarding the existence of specific receptors for electromagnetic fields as yet, one or the other person is certain of being able to notice the presence of electromagnetic fields. The perceptibility of microwave fields and related effects on short-term subjective effects have been tested in an experimental series. We found a) significant differences in the studied effects between experimental and control situations, b) stability of effects in retests, c) increasing correct indications concerning the presence of fields after several training sessions. Subjects could be discriminated regarding the individual level of effects. Moreover female versus male subjects showed different levels of correct indications of fields. The most important symptoms related to field detection are listed.

[The effect of a high-frequency electromagnetic field (2.45 GHz) on perceptual processes, psychological performance and well-being].

In a sample of 8 male subjects the effect of an ultra-highfrequency electromagnetic field (f = 2.45 GHz) with power densities of 1,000, 500 and 100 microW/cm2 was investigated. As parameters were used the perceptional threshold in a tachistoscopic perceptional test, the total time from the numbersearch-test and the sum of acute symptoms and complaints measured by a special questionnaire. At the highest field intensity on the one side increases of the total times and of the sum of complaints occurred. The differential threshold increased distinctly under 500 microW/cm2 exposure, whereas the total times and the sum of symptoms were not affected. At the lowest power density no differences between exposure and nonexposure conditions have been found. The intraindividual variability was considerable.

[Chronic neuropathy of the suprascapular nerve in high performance athletes].

The clinical and electrophysiological examination of 36 top-level volleyball players showed a suprascapular neuropathy in 28% of the subjects. The most commonly observed clinical symptom was a focal severe atrophy of the m. infraspinatus, combined with loss of strength of the arm in abduction and external rotation. In contrast to previous reports on suprascapular neuropathies in volleyball players, the present investigation demonstrates an additional milder affection also of the nerve fibres supplying the m. supraspinatus.

[Glomerulonephritis (GN) in childhood. II. Epidemiology and clinical aspects of various histological forms of glomerulonephritis].

From 101 children with histological verified glomerulonephritis the following data were analyzed according to the morphological alterations: age distribution, symptoms and onset of the disease, previous diseases, and observation time. Differences of these parameters were found firstly between minimal glomerular changes and proliferative lesions. Within the various proliferative forms the differences were minimal. In children with a diffuse mesangio-proliferative glomerulonephritis and MPGN the characteristics of blood pressure, proteinuria and hematuria were observed during a follow-up time of 5 years. In conclusion, a distinction between single types of glomerulonephritis could be made exceptionally without examination of kidney function and morphology.

[The incidence of kidney diseases in a pediatric kidney dispensary].

400 children (141 boys and 259 girls) in a renal disease care system were analyzed regarding their most frequent diagnoses of renal diseases and their age and sex distribution. Furthermore, the familiary situation, the time of observation, the number of consultations and the frequency of morphological changes of the kidney and the urinary tract were examined. 72% of the children suffered from urinary tract infection and in 10% a glomerulopathy and in 5.5% an urolithiasis were found. The symptoms of enuresis occurred in 22.2% of the patients. Infants were the most frequent age group (18%), 70% of which were boys. We found no differences in the incidence of renal diseases in comparison with other reports.

[Sickle cell disease in the People's Republic of Angola. 1. Epidemiology and clinical aspects].

In a period of 6 years 819 children affected with drepanocytosis (S. E.) were treated at the children's clinic in Luanda. At the time of diagnosis the age of the 457 boys amounted to 3.4 +/- 2.7 years and that of girls to 4.3 +/- 3.4 years. The age distribution shows that 40.2% of the patients were in their first 2 years of life. Conditions of crisis which affected 70% of the diseased children are typical of this disease. The family anemnesis demonstrated that 13.6% of all brothers and sisters covered were HbSS positive. 34.1% of them died at an age of 3.5 +/- 3.5 years (boys) or 2.4 +/- 2.3 years (girls) respectively. The physical development measured in the body mass shows that it is significantly diminished in comparison with healthy children of the same age. The characteristic symptom of this disease, splenomegaly, existed in 27.8% of the children with a mean age of 2.8 +/- 2.3 years. In one age group of 4.4 +/- 2.6 years it could even be identified in 11.3% of the cases.

[Sickle cell disease in the People's Republic of Angola. 2. Behavior of laboratory parameters].

In 819 children the Hb concentration, its dependence on the course of disease, the impact of various crises on Hb values and the behaviour of MCHC were evaluated. In the mean there was an anemia of 4.65 +/- 0.5 Hb mmol/l. In the course of 6 years a significant decline anemia of 4.65 +/- 0.5 Hb mmol/l. In the course of 6 years a significant decline of the Hb concentration could be observed. Only those crises connected with severe clinical symptoms (third degree) coincide with a significant Hb decrease. Every second child with a mean Hb value of 2.3 mml/l was transfused. In nearly half the cases there is a normochromic anemia, in 45.7% a hypochromic one. The mean serum bilirubin concentration lay at 31.6 mumol/l and increased with growing age of disease. The anemia has negative effects on the cardio-circulating system. The thorax-heart quotient shows a positive correlation to the degree of anemia.

[Oral galactose loading in characterizing the elimination and metabolizing performance of the liver in chronic renal failure].

For characterising the elimination and metabolisation performance of the liver in chronic renal insufficiency the galactose load test was carried out. 9 children with healthy liver and kidneys, 35 children with chronic renal insufficiency (15 were conservatively treated = group 1, 20 were in the chronic haemodialysis programme = group 2) as well as 5 children after kidney transplantation were examined. In group 1 a normal blood galactose concentration was present. Patients of the 2nd group showed increased concentrations of galactose in the blood which might refer to a decreased redox potential in the liver caused by the uraemic intoxication. In the group of patients who underwent a kidney transplantation in the patients with azathioprine therapy a disturbed use of galactose was present. Children with cyclosporin-A had a normal galactose concentration.

[Differential diagnosis of shoulder pain: chronic neuropathy of the suprascapular nerve].

Suprascapular neuropathy may present with chronic shoulder pain and weakness of abduction and external rotation of the arm. Therefore, it should always be included in the differential diagnosis of shoulder pain. Usually, the nerve is compressed at the suprascapular notch or the spinoglenoid notch. Here, the nerve is relatively fixed. In the etiology, repeated and forceful movements around the shoulder joint, especially in athletes such as volleyball players, are considered to be frequent causes of suprascapular nerve damage, whereas ligament hypertrophy and ganglia are uncommon. If conservative therapy fails, surgical decompression of the nerve is required for relief of pain and resolution of weakness.
