Life-style and dietary factors early and late in Parkinson's disease.

The study investigated features of life-style and dietary habits early and late in life of patients with idiopathic Parkinson's disease (IPD). Seventy-one patients and 103 controls were interviewed personally with a structured questionnaire. Living in villages during primary school time was significantly more frequent among patients, and in the urban environment patients had lived less frequently in larger-sized towns. Mushroom harvesting during childhood was more frequent among patients. No difference between patients and controls was found in childhood water supply, habits of fishing in the countryside or at the seaside, and eating such fish. Actual food preference in patients was greater for almonds and plums, while no difference was found in the actual intake of mushrooms, peanuts, oil-dressed salad, fish and animal offals. The study did not indicate a higher consumption of foods known to harbour heavy metals and pesticides in IPD patients either long before or during the disease. Reduced consumption of foodstuffs rich in vitamin E, as reported previously for premorbid patients, is no longer observed in patients with overt disease.

[Initial therapy of acute unilateral epididymitis using ofloxacin. I. Clinical and microbiological findings].

In a prospective study, 70 men suffering from uncomplicated acute unilateral epididymitis were treated initially with 2 x 200 mg ofloxacin p.o. per day for 14 days. Patients were reexamined at the end of therapy and again after 6 and 12 weeks. Patients were retreated when the pathogens had not been eliminated. Aetiologically epididymitis was caused in one-third of cases each by C. trachomatis (n = 20) and common urinary tract pathogens (n = 20); in the remaining one-third we found N. gonorrhoeae (n = 1). U. urealyticum (n = 3), or no pathogens (n = 26). At the first check-up examination, in 64/70 patients no pathogens were found. Relevant bacteria were still detected in 6 patients: C. trachomatis in 5 and E. aerogenes in 1. After 12 weeks, infection still persisted in 3 patients (E. coli, P. aeruginosa, enterococci). In vitro the microorganisms were invariably sensitive to ofloxacin. Due to abscess formation, surgical intervention became necessary in 6 patients. In 3 of these cases the causative agent was C. trachomatis. Regardless of the aetiology, after 12 weeks, in 20% of our patients the epididymis was still infiltrated and 14% complained of persistent symptoms.

[Initial therapy of acute unilateral epididymitis using ofloxacin. II. Andrological findings].

A total of 70 men suffering from uncomplicated acute unilateral epididymitis were enrolled in a prospective study. They were treated initially with 2 x 200 mg ofloxacin p.o. per day for 14 days, after which the spermatological examination was repeated for each. Ejaculate quality, i.e. density, motility, and morphology of spermatozoa, was determined on the last day of therapy, i.e. after 14 days, and again after 6 and 12 weeks. In most patients, initially decreased sperm counts increased significantly and global motility improved, while the numbers of abnormal spermatozoa decreased. Only in a few cases were azoospermia, kryptozoospermia, consistently reduced motility, and constant or even increasing numbers of deformed spermatozoa observed.

Goitre epidemiology: thyroid volume, iodine excretion, thyroglobulin and thyrotropin in Germany and Sweden.

Thyroid volume of 1397 German and 303 Swedish adults were estimated by sonography. Thyroid size of 6-16 year old Germans (n = 619) was determined and compared with findings on palpation. Thyroid volume was more than twice as great in German (21.4 +/- 15.6 ml, mean +/- SD) than in Swedish adults (10.1 +/- 4.9 ml). The echopattern was abnormal in 16% of the Germans and in 3.6% of the Swedes. German children have a thyroid volume ranging from 1.8 +/- 0.4 ml at 6 years to 10.8 +/- 6.0 ml at 16 years of age. Palpation is by comparison an unreliable method for determining thyroid size. In Germany, the iodine excretion was less in children (n = 619, 39.5 +/- 30.5, 34.1 micrograms I/g creatinine, mean +/- SD, median) than in adults (n = 1193, 83.7 +/- 94.4, 62.6), (P less than 0.001) and much lower than that observed in Sweden (adults n = 98, 170.2 +/- 93.3, 141.4; 13 year olds n = 113, 172.9 +/- 224.1, 124), (P less than 0.0001). Serum thyrotropin concentration was significantly higher (P less than 0.001) in Sweden (n = 62, 1.49 +/- 0.82 mU/ml), than in Germany (n = 91, 0.97 +/- 0.52 mU/ml), while serum thyroglobulin was increased in Germany (n = 91, 72.6 +/- 50.6 micrograms/l) as compared to Sweden (n = 62, 23.5 +/- 17.4), (P less than 0.0001). These results indicate the goitrogenic effect of iodine deficiency and the continuing need for an effective iodine prophylaxis in the FRG.

Ureaplasmal infections of the male urogenital tract, in particular prostatitis, and semen quality.

Ureaplasma urealyticum is considered an etiologic agent in urogenital tract infections, especially prostatitis. Using the 'four-specimen technique', diagnosis can be based upon significant numbers of these microorganisms. In ejaculate, the critical number seems to be 10(3) cfu/ml of semen to discriminate between real infection and contamination during urethral passage. In our study, 46 of 412 samples (11.2%) exceeded this critical number. Most but not all patients suffering from ureaplasma-associated prostatitis established by the 'four-specimen technique' revealed significantly high ejaculate numbers, whereas all samples from patients with prostatodynia and healthy controls had lower numbers. In these cases, numbers of round cells in semen, i.e. all leukocytes and spermatides, were significantly increased as compared to prostatodynia. A significantly negative correlation was detected between the numbers of ureaplasmas and zinc concentration in semen, and an almost identically negative correlation to the content of fructose, thus indicating secretory dysfunction of the accessory glands in ureaplasmal infections of the prostate.

[Bolus geometry in various central and peripheral contrast medium applications: study with serial CT using non-ionic contrast media].

Measurements of concentration in 27 patients with a calibrated Serio-CT yielded for the intravasal contrast medium bolus maximum a value of approx. 23 mg I/ml for the a. carotis with central injection and approx. 14 mg I/ml for the a. iliaca with peripheral injection. 7 invasive measurements were performed at the bifurcation of the aorta, yielding a value of 12.5 mg I/ml with peripheral injection. In all these cases, 40 ml nonionic contrast medium (Iohexol) with an iodine content of 350 mg I/ml were applied. The average bolus half-life was 9.5 sec. measured at the carotid artery, 11.5 sec. at the a. iliaca, and 7 sec. at the bifurcation of the aorta. Differences in bolus geometry were not seen on comparing arterial injection with cava superior injection; likewise, there were no differences between peripheral injections at various speeds. Animal experiments reported in literature show that these observations can be mainly ascribed to vascular dilatation in the minor circulation produced by the contrast medium.

[Platin-containing cytostatic combinations in the therapy of advanced gynecologic carcinomas].

95 patients with advanced and recurred gynecological carcinomas (57 ovarian carcinoma, 22 cervical carcinoma) were treated by a platinum (CDDP) based polychemotherapy platinum, adriamycine, cyclophosphamide (PAC); platinum, adriamycine, bleomycine (PAB), 22 out of 48 patients with low differentiated epithelial carcinoma of the ovary stage III and IV achieved a remission (13 CR; 9 PR). Today 6 of the CR-patients survive 23 months without recurrence; 7 had a medium survival of 17 months. Medium survival of PR-patients was 15 months. 6 NED-patients survive 22 months without recurrence and 2 NED-patients died after 19,5 months. The overall response rate (CR, PR, NED) was 63%. A retrospective comparison with 78 patients (low differentiated ovarian carcinoma stage III and IV) treated by a cyclophosphamide monotherapy shows an elevated 2-year survival rate of the PAC treated patients. The other patients suffered from carcinoma of the mamma, the tubes, the corpus uteri, the vagina, and the vulva. The therapeutic effect of CDDP based polychemotherapy cannot be judged because of the small number of cases; but the side effects at these patients were registered thoroughly. Side effects of totally 514 therapeutic cycles (460 mg CDDP per patient, 78 mg CDDP per cycle) are presented.

Ultrastructural and ultrahistochemical investigations of lead-induced intranuclear inclusion bodies in rat kidney.

The morphogenesis of intranuclear inclusion bodies in the proximal convoluted tubules of rat kidney is studied in chronic lead poisoning. In early stages electron dense particles and fibrillar structures in connection with interchromatin granules were observed. The fully developed inclusion bodies showed an electron dense core from which fibrils project outwards forming an irregular coronal framework. By the sulphide silver method for the demonstration of heavy metals an intense reaction was observed in the outer areas of the fibrillar corona after digestion using DNase.

[Strategies used by patients with lateral telangiectatic naevi to handle their problems].

Considering the suitableness of operative therapies for remarkable skin defects without progrediency or malignity, we studied patients' feelings, cognitions and ways of acting with a special questionnaire. The forms were filled in by 28 patients with lateral telangiectatic naevi and a control group of 60 persons with normally constituted skin. The results did not show significant differences between the two groups. Therefore, the indications for surgery or radiotherapy have to be set up very cautiously.

[Attempt at applying statistical methods to delimit melanoma types].

By means of the "multivariate variance analysis" ("MANOVA"; Friedrich and Olfert, 1977), we tried to differentiate the histologic types of malignant melanomas also by quantifiable criteria. The investigation depended upon data from 411 patients. Difficulties arose from incomplete data material. But in principle, the indication of this method is given in such problems. If the number of cases could be augmented, the method would be helpful as a support for diagnostic quality control.

[Accuracy of the clinical diagnosis in malignant melanomas].

Histologic findings and clinical data of 411 patients with malignant melanomas treated in 1952 up to june 1977 reveal an improvement of diagnostic accuracy. Within the last years, fewer patients were referred to the clinic with extensive tumor growth or with metastases. A change from the levels of invasion V and IV to III is evident. Further improvement to level II and I with a corresponding smaller tumor thickness is appearing in outlines.

[Attempt of a definite statement on dental care for the handicapped].

A survey made in cooperation with various institutions for the handicapped ascertained the dental coverage and care of the handicapped. Participating in the survey were 634 institutions for the handicapped. The study included 98,737 handicapped individuals treated on both an in-patient and an out-patient basis in these institutions. The results of the survey tend to indicate that dental care for the handicapped is in need of improvement.
