After Cologne: male circumcision and the law. Parental right, religious liberty or criminal assault?

Non-therapeutic circumcision violates boys' right to bodily integrity as well as to self-determination. There is neither any verifiable medical advantage connected with the intervention nor is it painless nor without significant risks. Possible negative consequences for the psychosexual development of circumcised boys (due to substantial loss of highly erogenous tissue) have not yet been sufficiently explored, but appear to ensue in a significant number of cases.

[Malignant epithelioid schwannoma of the inferior alveolar nerve.Case report with review of the literature].

Malignant epithelioid schwannoma is a very rare disease originating from the Schwann cells. It is a subtype of malignant schwannoma. The limbs are the main location of this entity.

[Focal oncocytosis of the salivary glands and etiopathogenetic relations].

Focal oncocytosis in minor and major salivary glands is a relatively rare condition. We found it in 92 (8.7%) of 1056 biopsy and operation specimens of the salivary glands.

[primary and secondary malignant liver tumors at autopsy, biopsy and cytology: frequency and problems of differential diagnosis].

The frequency and ratio of primary and secondary malignant liver tumours were evaluated in the autopsy, biopsy and cytology files from 1980 to 1994. In 1008 necropsies with hepatic malignancies, 91 primary liver carcinomas and 917 metastatic liver tumours were observed. In a total of 2537 malignant neoplasias at autopsy, the overall-rate of liver metastases amounted to 36%.

Light and electron microscopic studies of lectin binding to the glycocalyx of rat pancreatic cells. II. Light microscopic changes after induction of an olive-oil pancreatitis.

Using a battery of 7 horseradish peroxidase marked lectins (WGA, RCA I, PHA, LCA, PNA, UEA I, LPA) or 2 unmarked lectins (Con A, VAA I) and HRP-marked antibodies, the binding to acinar cells with a postembedding technique on semithin sections of rat pancreatic tissue after olive-oil pancreatitis was studied light microscopically. The lectin binding of the normal healthy rat pancreatic tissue (Jonas et al. 1991) changed remarkably.

[The ameloblastic fibro-odontoma--an odontogenic mixed tumor progressing into an odontogenic sarcoma].

A case report is given on the rare course of an ameloblastic odontoma which originated from the right mandible in a girl at the age of 14. During the follow-up of 12 years there where 4 recurrences with a change in the histological findings. While ameloblastic epithelial complexes were found to be ever decreasing, there was, on the other hand, an increase in the mesenchymal component with foci of a marked proliferation of spindle cellular fibroblastic elements.

[Lymph drainage disorder as a pathogenetic co-factor in acute pancreatitis?].

Experiments performed on 71 Wistar rats confirm that preexisting interruption of lymph drainage by ligation of the ductus thoracicus can have a major influence on the development of pancreatitis. The effect of a ductus hepatopancreaticus blockade in experimental group A (32 animals) was greatly exacerbated by previous ligation of the ductus thoracicus (experimental group B; 34 animals). Edema of the interstitial pancreatic tissue led to lipolytic necrotizing pancreatitis with a slight hemorrhagic component, increasing ascites after the 12 th hour of the experiment, and numerous abdominal fat necroses after about 19 hours, but only relatively minor necroses of acinar parenchyma cells in the pancreas.

[Meteoropathologic effects on the development of fatal lung embolism].

The metoropathological analysis of 958 fatal lung embolisms in the territory of Rostock does not make notice of special relation of the summer, preparing the material acc. to the both main seasons. In winter the fine weather phases 1-4 and normal radiation conditions result in a significant increase of the rate of mortality.

[The incidence of fatal lung emboli with special reference to the underlying disease and the effect of weather].

The frequency of the fatal pulmonary embolism in the autopsy material of Rostock University undergoes greater variations. After an increase of the incidence in connection with hyperalimentation and increase of age to the twofold to threefold between 1922 and 1974 as possible sequel of a prophylaxis of thrombosis a decrease of maximally 12.4 to 8.

[The morphogenesis of the structural changes of the exocrine pancreas after ligation of the excretory duct].

Unlabelled: The changes in the exocrine pancreas were investigated after ligature of the excretory duct in 51 Wistar rats. A qualitative microdetermination of the epithelial cells was carried out in the originated ductulus-like structures.

Conclusions: The acinic epithelial cells grow atrophically first of all and become necrotic in the end.

[Detection of fibria-like surface structures in Staphylococcus saprophyticus as a pathogen in chronic pyelonephritis].

It is reported on a 25-year-old female patient suffering from chronic pyelonephritis. Six times coagulase-negative staphylococci were bacteriological proved in a significant number. Four strains were identified as Staphylococcus saprophyticus.

Detection of different fimbriae-like structures on the surface of Staphylococcus saprophyticus.

In relation to the ability of adhesiveness to HEp-2-cells the sizes of capsules on three strains of Staphylococcus saprophyticus were examined using an electron microscopic India ink technique. There was a good correlation between small amounts of capsular material and good adherence to the tissue culture cells. In contrast to this a very large capsule could be demonstrated on a strain which adhered only in a poor manner.

[Hemorheological/hemodynamic study on miniaturized capillary filters in the concept of an implantable artificial kidney].

The conception of an implantable kidney provides the substitute of the non-functioning kidney by a technical-biological system. The filtration function is to be performed by a capillary hemofilter. The results obtained in an open test circulation on 3 filters produced by optimum aspects were represented and compared with the physiological performance parameters of the kidney.

[Hemocompatibility testing in the rat model by noninvasive blood flow measurement using an arteriovenous shunt].

The flowing periods of blood through biomaterial shunts were measured by means of a noninvasive sensor with sufficient reliability. Falsifications of the measuring results by foreign influences as roller pumps, punctures, changes of the cross section, or the coupling of different materials were avoided extensively. The accomplishment of the test is possible routinely without a great display of apparatus.

Significance of disturbed lymph flow for the pathogenesis of pancreatitis. I. Ligature of the ductus thoracicus in the rat.

To examine the significance of a disturbed lymph drainage for the pathogenesis of acute necrotizing pancreatitis, thoracic duct ligation was performed in 53 Wistar rats. Histological examination of the pancreas and analysis of serum lipase and serum amylase were carried out at various time intervals from 1 h to 42 days after initiating the experiment. Sudden stop of the lymph flow induced a long lasting pancreatic edema, initially in the perilobular interstitium and eventually also within some lobules, with scattered necroses of whole acini or single acinar cells mainly in the peripheral zones of the lobuli.

Electron microscopic results on the ventral prostate of the rat after CdCl2 administration. A contribution towards etiology of the cancer of the prostate.

The prostate epithelium of rats which received repeated cadmium chloride (CdCl2) injections showed a gradual disruption of structural differentiation. Electron microscopy studies revealed severe changes in the ultrastructure affecting all epithelial cell organelles, particularly the nuclei, rough endoplasmatic reticulum, the golgi apparatus, and mitochondria. The cells infiltrating the stroma contained secretory vacuoles and their nuclear evaginations on the invasion front showed similarities to ultrastructural pathological changes in man.

[Relations between atypical hyperplasia, dysplasia and prostatic cancer and the significance of its appearance for the clinician].

In 89 preparations of patients with a carcinoma of the prostate and 100 preparations of patients with a hyperplasia of the prostate (adenoma of the neck of the bladder) the appearance of primarily atypical hyperplasias was investigated. In these cases in the carcinoma group in the uniform as well as in the pluriform carcinomas a coincidence of carcinoma and atypical hyperplasia of 55% was found. The coincidence is particularly high in adenocarcinomas and in carcinomas with dominating adenoid part, respectively, i.

[Ideal experimental microsurgical methods in vasovasostomy and vasoepididymostomy].

The vasovasostomy with the double-layered end-to-end anastomosis by Silber is a microsurgical ideal method. We think we found experimentally an ideal method for the vasoepididymostomy with the open end-to-side anastomosis and direct spermato-tight microsurgical suture. Specialties of the species rat and dog have to be observed.
