Nutritional assessment: indications and applications.

The application of objective measures of protein and caloric compartments as well as immunocompetence reveal that approximately 50 percent of hospitalized patients are malnourished. The performance of a nutritional assessment, by a joint effort of hospital personnel, in patients with subclinical or early clinical malnutrition obviates potential complications through early institution of nutritional support. Prudent, logical decisions based on objective data can then be made regarding future patient care resulting in decreased hospitalization, and lower septic and mortality rates.

Occlusion of the cerebral arteries in Recklinghausen's disease.

Two children, aged 18 months and 6 years, who had Recklinghausen's disease, had occlusion of cerebral arteries. One child had no motor deficit but the other had right hemiparesis and partial occlusion of the left posterior cerebral artery, a fact not found in the literature.

Kinetic complexity of nuclear poly(A)-containing RNA in normal and regenerating rat liver.

Poly(A)-containing RNA isolated from liver nuclei of untreated rats and 3 h or 12 h after partial hepatectomy or sham operation was hybridized to the complementary DNAs (cDNAs). In the homologous reactions two major components could be seen. When compared to normal liver, the complexity of the least abundant class was lower in nuclei from livers 3 h after partial hepatectomy and was higher in those isolated 12 h after operation. The heterologous reactions revealed an increase of some abundant poly(A)-containing sequences and a loss or dilution of rare sequences 3 h after operation. The latter effect was not specific to the regeneration process but occurred after laparotomy as well. 12 h after partial hepatectomy, however, about 10% new poly(A)-containing sequences were detected, corresponding to about 5000 molecules of 4500 nucleotides length, which are unique to regenerating nuclei.

The wide spectrum of the asphyxiating thoracic dysplasia.

Seven cases of A. T. D. are presented. Radiological findings were extraordinarily diverse. The prognosis of the disease is difficult for each individual case, because of the frequent pulmonary complications and cystic renal lesions are not always directly related to the severity of the bone changes. The authors believe that the term "thoracic-pelvic-phalangeal dysplasia" proposed by Langer, is the most adequate, since it points to the key factors in the diagnosis of the disease.

Congenital atresia of the foramen of Monro.

Two cases of congenital atresia of the foramen of Monro are described, one 8 days old and the other 2 months old. Both are associated with a parieto-occipital paraventricular diverticulum and spontaneous ventriculostomy with the passing of the cerebrospinal fluid to the posterior fossa and the formation of a cyst in the supracerebella region which compressed and displaced the structures of the posterior fossa.

Traumatic neuroma: a complication of transcanal labyrinthectomy.

Transcanal labyrinthectomy is frequently unsuccessful in controlling vertigo due to intractable Meniere's disease. It may in fact make the condition worse due to the formation of a traumatic neuroma. The translabyrinthine vestibular nerve section is more reliable, but the morbidity is greater. Therefore, the transcanal procedure is usually recommended as the initial procedure, but the patient is warned that a second more extensive procedure may be necessary to control dizziness.

Purification and reverse transcription of the messenger RNA coding for the insect protein, calliphorin, isolated from larvae of the blowfly, Calliphora vicina R.-D.

Starting from poly(A)-containing RNA prepared from the fat body of larvae of the blowfly Calliphora vicina, we have purified an mRNA coding for the protein calliphorin, which is a major blowfly protein accounting for approximately 9% of the total poly(A)-containing mRNA activity in the fat body of 5-days-old larvae, as demonstrated by translation in vitro. The mRNA for this protein was purified by sucrose gradient centrifugation under denaturing conditions and identified by cell-free translation. The peak fraction of the gradient shows three bands of about 20 S after formamide/acrylamide gel electrophoresis. Using reverse transcriptase and Calliphora mRNA isolated directly from the acrylamide gel electrophoresis or from sucrose gradients, we synthesized a cDNA probe. This cDNA hybridizes with the template, showing a major kinetic component with a molecular weight of 2.8 x 10(6), fitting well with the three bands observed in the electrophoresis. Hybridization of the cDNA with total sonicated Calliphora DNA shows annealing only at very high c0t values, indicating that Calliphora mRNA is transcribed from the unique portion of the fly genome.

Spontaneous ventriculostomy and ventricular diverticulum.

Four cases of ventricular diverticulum are presented, 2 with spontaneous ventriculostomy. In 2 patients, the cause was monoventricular hydrocephalus through congenital stenosis of the foramen of Monro, with paraventricular diverticula and spontaneous ventriculostomy. Both patients had a cystic space in the quadrigeminal and supracerebellar cistern. In one patient during pneumoencephalography, the ventricular diverticulum filled via the ventriculostomy. The other 2 patients had congenital stenosis of the Sylvian aqueduct with the formation of a large supratentoria cyst connecting with the posterior part of the third ventricule.

Effect of bleeding on irradiation-induced erythropoiesis in the spleen of AKR mice.

The effect of erythropoietin, increased by bleeding, on the erythropoiesis induced by irradiation in the spleen of AKR mice, has been studied. The following parameters were measured to quantify the erythropoietic activity: the number and size of hematopoietic nodules (colonies) and proerythroblasts in the spleen, the spleen, blood and red-cell 59Fe uptake and the hematocrit and reticulocytes in the blood. Under erythropoietic stimulus an increase in the number and size of colonies was observed and these colonies were observed sooner because of their more rapid growth. The proerythroblasts in the spleen appeared earlier, and there were increases in the spleen, blood and red-cell 59Fe uptake and in the hematocrit and reticulocytes in the blood.
