pulmonary gas exchange and exercise performance in pulmonary hypertension.patients with pulmonary hypertension have disordered pulmonary gas exchange and impaired exercise tolerance. the hypoxemia is due to mild ventilation-perfusion (va/q) inequality exaggerated by the presence of a low mixed venous po2 (pvo2) and is accentuated during exercise due to a further fall in pvo2. this in turn may be worsened by vasodilators which increase the degree of va/q inequality. decreased exercise tolerance is due predominantly to cardiac limitation, and thus an improvement in card ...20144042731

cerebrospinal fluid vasopressin in neurological and psychiatric disorders.vasopressin was determined in csf and plasma of 243 patients with different neurological and psychiatric disorders, including control patients. csf vasopressin was significantly higher in patients with high pressure hydrocephalus, intracranial tumour, benign intracranial hypertension, intracranial haemorrhage, ischaemic stroke, and craniocerebral trauma. in patients with primary degenerative dementia, csf vasopressin was lower than in control patients. among patients with psychiatric disorders, ...20143973621
intraoperative autologous transfusion.intraoperative autologous transfusion is a technique that was first used almost 2 centuries ago but that has realized its potential only in the past 5 years. a growing national awareness of transfusion-related morbidity, of the need for alternative blood sources, and of improved methods for red blood cell recovery has led to an increased frequency of use of autologous transfusion. most hospital programs use semicontinuous flow centrifugation or canister technology for the intraoperative salvage ...20143919219
neuroblastoma and nutritional support: influence on the host-tumor relationship.the nutritional sequelae of neuroblastoma are secondary to tumor burden, tumor-host influenced metabolism, and antitumor operative, pharmacologic, and radiation therapy. nutritional support and its influence on the outcome of clinical cancer is confusing; but in a defined murine system, we hypothesized that whether or not nutritional repletion favors the host-tumor relationship is dependent on a nutritional augmentation of host antitumor immunity. c1300 murine neuroblastoma (nb) elicits a host a ...20143958885

[septum deviation and concomitant sinusitis].it is generally assumed that there is a relation between nasal obstruction due to deformities of the nasal septum and disease of the paranasal sinuses. we investigated patients with septal deviation and rhinomanometrically determined nasal obstruction and checked the sinuses before septal surgery by radiography, ultrasonography, and endoscopy. the results of our investigation on 150 unselected patients during 1983 support the hypothesis. we found that non-invasive diagnostic methods, i.e. radiog ...20143910625
application of microvascular free osteocutaneous flaps in the management of post-radiation recurrent oral cancer.fifty-nine patients underwent free flap osteocutaneous reconstruction that consisted of flaps of the dorsum of the foot in 26 patients and iliac crest flaps in 33 with a success rate of 92 percent and a mortality rate of 1.6 percent. these flaps, which require the expertise of microvascular surgeons, are time-consuming and complicate operating room and time management, but they represent a remarkable advance in reconstruction that can facilitate cosmetic and functional recovery of the patient. i ...20143901789

technology in ambulatory medical care: cost increasing or cost saving?health insurers fear that increased use of medical technology in ambulatory care results in increased billings per physician. this view may overlook certain subtle links between available, appropriated technology in ambulatory practice and the propensity to hospitalize a marginal patient. in this paper, the impacts of technology on four components of total per physician treatment cost were analyzed statistically using 1976-1978 percentage changes for a sample of more than 700 swiss physicians: n ...20144081817
blood banking in the united states--1981.combined data from the american association of blood banks, american national red cross, and community council of blood centers for 1981 compared to similar data for 1980 show an increase in the collection and use of blood and components. in 1981, a greater percent of donor units was converted to multiple components. use of blood resources was more efficient in 1981 than in 1980.20144024226
polymorphic metabolism of metoprolol: clinical studies.after a single 200 mg oral dose of metoprolol tartrate the mean metoprolol auc was found to be six-fold higher in poor metabolizers (pms) of debrisoquine than in extensive metabolizers (ems). this was associated with impaired metabolic clearance via alpha-hydroxylation and o-dealkylation. a population study (n = 143) has shown a bimodal distribution in the ratio of metoprolol: alpha-hydroxymetoprolol recovered in urine which was correlated highly with the debrisoquine metabolic ratio. nine per c ...20144054194
quantitative analysis of veralipride in plasma and urine by gas chromatography-mass spectrometry and gas chromatography with flame-ionization detection.a highly sensitive and selective quantitative assay for unchanged veralipride has been developed. the compound is extracted from alkalized samples (plasma or urine) with dichloromethane and converted to its trimethylated derivative by reaction with trimethylanilinium hydroxide. the reaction mixture is then chromatographed on a 3% ov-1 column. trimethylated derivatives of plasma samples were assayed by selected-ion monitoring in the chemical-ionization mode and quantified by comparing the intensi ...20144019658
urinary retention secondary to ovarian dysgerminoma in a girl.a thirteen-year-old girl sought medical advice because of a markedly weakened urinary stream with severe hesitancy. she was referred to the pediatric clinic because of 3 episodes of acute urinary retention during a previous month. pelvic examination showed a retrovesical tumor. an excretory urogram revealed bilateral ureterectasis and pyelocalicectasis. two weeks after left nephrostomy, surgical exploration demonstrated a right ovarian mass causing compression of the left ureter and obstruction ...20144012986

interpeak intervals of auditory brainstem response, interaural differences in normal-hearing subjects and patients with sensorineural hearing loss.abr recordings were made on 31 normal-hearing subjects and 253 patients with sensorineural hearing loss (86 patients with unilateral hearing loss, 61 patients with asymmetrical hearing loss, 34 patients with symmetrical hearing loss, 55 patients with noise-induced hearing loss and 17 patients in the late chronic stage of menière's disease). in the patient group with unilateral hearing loss, the mean interpeak interval (ipi) i-v was significantly shorter than in normal-hearing subjects. the inter ...20144023603
mitral valve prolapse in sickle cell disease: manifestation of a generalized connective tissue disorder.previous studies have shown an association of sickle cell disease with generalized connective tissue disorders such as pseudoxanthoma elasticum. we recently documented an unexpectedly high prevalence of mitral valve prolapse, a connective tissue disorder, in sickle cell disease. to investigate this association, skin biopsies were analyzed from 32 sickle cell disease patients, 11 of whom had mitral prolapse. total and type iii collagen, collagen solubility, and uronic acid were not different betw ...20143985003
detection of the c-myc oncogene product in testicular cancer.a set of monoclonal antibodies was constructed by immunising mice with peptide fragments of the c-myc oncogene product. one such antibody, myc 1-6e10 was shown to bind to a 62,000 dalton protein identifiable with the c-myc product (p62c-myc). the antigen recognised was not destroyed by paraffin wax embedding. myc 1-6e10 was used to characterise the distribution of p62c-myc in archival testicular tumour material. normal testes expressed only small amounts of p62c-myc. seminomas showed increased n ...20144027160

recent advances in cardiac surgery.virtually all forms of congenital heart disease can be repaired or significantly palliated. the risk of surgery in infancy continues to decline, and many lesions are being routinely repaired at an early age. this may permit an improved functional result later in life. other recent advances include the arterial switch procedure for transposition of the great arteries, the palliative repair of hypoplastic left heart syndrome, and the increased application of the fontan procedure in patients with o ...20143897982
cerebral blood flow and brain atrophy correlated by xenon contrast ct scanning.correlations between cerebral blood flow (cbf) measured during stable xenon contrast ct scanning and standard ct indices of brain atrophy were investigated in the patients with senile dementia of alzheimer type, multi-infarct dementia and idiopathic parkinson's disease. compared to age-matched normal volunteers, significant correlations were found in patients with idiopathic parkinson's disease between cortical and subcortical gray matter blood flow and brain atrophy estimated by the ventricular ...20143879209
defects in pulsatile lh release in normally menstruating runners.intense physical exercise has been associated with reproductive dysfunction and menstrual cycles may be abnormal in a majority of women with a heavy training load. to determine whether training influenced pulsatile lh release, we measured lh pulse frequency, lh pulse amplitude and area under the curve over six hours during the early follicular phase of the menstrual cycle in four sedentary women and six eumenorrheic women runners with a training volume of at least 32 km per week. all three lh va ...20143972973
ultrastructure in septa in blastobotrys and sporothrix.transmission electron micrographs of septa in blastobotrys species invariably showed central micropores. septa of species of sporothrix, however, exhibited three types of pores: micropores which were central if single, or scattered; central simple pores with woronin bodies; dolipores. the results confirm the heterogeneity of the genus sporothrix.20144039913
