Rhizomelic bone dysplasia with club-like femora (case report and confirmation of a syndrome).

A newborn with rhizomelic bone dysplasia with club-like femora is reported. This is the fourth case of this easily recognizable, recently reported, congenital bone disease. Maroteaux et al recently reported two patients with rhizomelic bone dysplasia and club-like femora as a distinctive new bone dysplasia. Their observation was confirmed by Gugliantini et al (2) who reported another case. This paper reports a fourth patient with this easily recognisable disorder.

Estimation of the optimal tissue oxygenation parameters in adult respiratory distress syndrome (ARDS).

We hypothesised earlier that the simultaneous examination of the basic tissue oxygenation parameters (O2 delivery-DO2, O2 extraction ratio-O2ER, O2 consumption-VO2) results in a more adequate relationship to characterize the oxidative metabolism of tissues than a separate evaluation. The aim of present study was to prove this hypothesis. That is for while the results of these oxygenation measurements were examined simultaneously in a 3-dimensional analysis in 30 patients with ARDS. It was found that all measured values distributed on a 3-dimensional space net. An optimal range on the tissue oxygenation surface could be separated where 64% of the data of survivors were inside this range, while 77% of the data of "late stage" nonsurvivors--patients, where the measurement were done on the last 5 days of their life--were outside this range. The therapeutic goal in the treatment of ARDS patients is to change the oxygenation parameters to be inside this optimal range.

Dynorphin A-containing neural elements in the nucleus of the solitary tract of the rat. Light and electron microscopic immunohistochemistry.

Distribution of dynorphin A (DyA) immunoreactivity in the nucleus of the solitary tract (NTS) was examined in rats after various surgical transections by light and electron microscopic immunohistochemistry. In colchicine-treated animals DyA immunostained perikarya were seen in each subdivision of the NTS. In intact rats, dense network of immunopositive nerve fibers was localized light microscopically, and synaptic contacts were found between DyA immunopositive structures (axo-axonic, axo-dendritic synapses), electron microscopically. Surgical transections medial, caudal or rostral to the nucleus did not alter the distribution pattern of DyA in the NTS. Lesion immediately lateral to the nucleus resulted in an ipsilateral appearance of immunostained cell bodies. Vagal and glossopharyngeal afferents (including baroreceptor fibers) terminate in the medial and commissural subnucleus of the NTS. Two days after extracranial vagotomy, synaptic contacts between degenerated presynaptic boutons and DyA immunopositive postsynaptic elements were observed in both medial and commissural part of the NTS. These observations provide morphological evidence suggesting that (1) axons of dynorphin A-containing cell bodies form an intrinsic network inside the nucleus; (2) these DyA cells receive direct peripheral inputs through the vagus nerve, and (3) projecting DyA neurons may exist in the NTS, they may innervate medullary, rather than forebrain, higher brainstem or spinal cord neurons.

Structural studies on the immunogenic form of the enterobacterial common antigen.

It has been shown that enterobacterial common antigen is chemically linked to the hexose region of the R1-type lipopolysaccharide fo the Escherichia coli strain F470 which is immunogenic for this antigen. The number of R core stubs substituted is very small but it is a-parently sufficient to induce antibody formation to the enterobacterial common antigen in the rabbit.

A hitherto undescribed case of "collision" tumour: liposarcoma of the seminal vesicle and prostatic carcinoma.

A hitherto undescribed type of the rare "collision" tumours is reported: necropsy in a 77-year-old male patient revealed liposarcoma of the right seminal vesicle in association with anaplastic carcinoma of the prostate. The carcinoma was fused with the liposarcoma as a result of its invasive local growth and had formed deposits in the lymph nodes, bones and lungs. The left seminal vesicle showed localized amyloidosis. A review of the published cases of mesenchymal tumours of the seminal vesicles is presented.

[Acrodermatitis enteropathica (author's transl)].

In connection with the clinical observation of their five patients suffering from AE the authors summarize current questions related to this disease. They examined the function of the cellular immunity in this disease. They call attention to dangers of oxychinoline treatment, and to benefits of zinc administration. They established that the introduction of zinc therapy indicates a progress in the treatment of AE.

Mild variant of maple syrup urine disease.

The case of a three-year-old boy with mental retardation, moderate muscular hypotony and speech delay is presented. The mild form of maple syrup urine disease was suspected at the first blood screening test by means of ion-exchange thin-layer chromatography. The diagnosis was confirmed by quantitative serum amino acid analysis and protein loading. On a low protein (2 g/kg body weight) diet completed with leucine-isoleucine-valine free formula prompt and lasting normalization of the serum amino acid level ensued with steady improvement of the clinical and neurological status.

Ambiguous genitals and the choice of gender.

In 8 children with ambiguous external genitals, sex chromosome, hormonal and histological examinations were performed. On this basis the registered sex and the surname of the child were changed from the registered male to female in 3 cases and from female to male in one case. Diagnosis and the decision about the gender are urgent tasks, since prolonged waiting may have serious consequences in psychosexual development.

Nationwide investigation of multiple malformations.

A nationwide programme for the evaluation of 1,339 newborns with multiple malformations (about 8% of all malformed babies) notified to the Hungarian Congenital Malformation Registry in the period 1973 to 1975, was launched on January 1st, 1973. As specific syndromes and anomalads, 696 cases (51.9%) were notified. On the basis of individual malformations, 87 cases were identified from 439 patients with notified associations, and 27 multiple malformations among 172 stillborns and infant deaths were recognized from autopsy records collected from pathologists. 341 surviving infants were officially referred to 'multiple malformation centres' for special examination. 57 infants of 129 cooperating families were identified. Benefits of this programme are (i) the proportion of specific syndromes and anomalads increased by 12.8%; (ii) the rate of unspecified multiple malformations decreased by 56.6%; (iii) examination of multiple malformations may be the most sensitive means to detect teratogens; (iv) 50.5% of the expected number of chromosome abnormalities in newborns was found; (v) the nationwide material of multiple malformed babies offers a possibility to clarify gene abnormalities and new syndromes.
