Effects of 24-hour ambulatory blood pressure monitoring on daily activities.

Compared the self-monitored activities, locations, and postural positions of 28 hypertensives while they wore an alarm watch and then while they wore a 24-hr ambulatory blood pressure monitor (ABPM) to see if wearing the ABPM led to alterations in behavior. Within the limitations of the study (no counterbalancing of order and twice as many ABPM measures as watch measures), we found significant differences in frequency of being at home or in miscellaneous settings, in standing and reclining positions, and in mental, physical and miscellaneous activities between the two occasions.

[Iatrogenic ligation of the common bile duct. Diagnostic value of percutaneous insertion of an angioplasty balloon catheter].

The authors report a case of surgical ligation of the common bile duct and discuss the retrograde and transhepatic cholangiographic features. The stenosis was more extensive than suggested by the cause of the obstruction. The transhepatic insertion of a balloon catheter demonstrated the ligature by showing a zone of concentric constriction. The ligature was unable to be ruptured by means of an angioplasty catheter, which would nevertheless appear to be a dangerous technique.

Knowledge of hemodialysis and CAPD patients about their prescribed medicines.

A questionnaire was designed to determine and compare the extent of knowledge of 40 continuous ambulatory peritoneal dialysis (CAPD) and 40 hemodialysis (HD) patients about their medicines. It was administered orally to outpatients attending a clinic by an investigator unknown to the patients. Data were collected pertaining to the following target drugs: calcium supplements, phosphate binders, vitamins B and C and folic acid. HD and CAPD groups were closely matched for age and sex. Sixty percent of CAPD and 49% of HD patients were taking four or more medications. The dose of folic acid was accurately recalled by 91% and 71% of CAPD and HD patients. Indications for calcium supplements and phosphate binders were known by only 8% and 30% of CAPD patients compared to 72% and 73% of HD patients. More HD patients knew the indications for all target drugs (p less than 0.01). More CAPD than HD patients knew the expected duration of therapy (p less than 0.01). There was a trend between decreased knowledge of whether the medication was working with increasing age of CAPD patients. Most drug information was supplied by physicians, but many CAPD patients (21%) obtained information from lay sources. When given the opportunity to ask questions about their medicines, only 56% CAPD and 46% HD patients did so. The knowledge of CAPD and HD patients studied was grossly deficient in terms of indications, effectiveness, duration and action to be taken if doses were missed.

Incidence of CAPD peritonitis in patients using UVXD or O-set systems.

Eighty-one patients were placed either on the O-set (39) or the UVXD germicidal system (42). Total experience was 13.7 +/- 8.0 and 17.8 +/- 14.8 months, respectively. There were 48 and 85 new episodes of peritonitis in 24 and 28 patients, respectively, and an additional 11 and 28 episodes of relapse or probable relapse. The peritonitis rate was 1 episode each 11.14 and 8.83 patient months, which was not significantly different. There was no significant difference between the 2 groups in terms of the mean numbers of peritonitis-free days (393.7 versus 503.8) or in the mean time to the first episode of peritonitis (6.60 versus 6.54 months). The odds ratio of relative risk of peritonitis with the two systems was 1:1.17 (O-set:UVXD). There appears to be no difference in ability of the two systems to prevent peritonitis.

Atheroembolic renal disease: association with renal arterial stenosis.

In elderly patients with generalized atherosclerosis and longstanding hypertension, progressive renal insufficiency should suggest renal artery occlusive disease and/or renal cholesterol embolization. Renal cholesterol embolization is not an absolute contraindication to successful surgical revascularization. Renal cholesterol emboli were identified in biopsy specimens obtained in 24 cases at the Cleveland Clinic from 1978 to 1986, and renal artery stenosis was an associated finding in 19. Clinical manifestations of generalized atherosclerosis were common, including ileofemoral atherosclerosis (18), coronary artery disease (16), carotid occlusive disease (15), and carotid occlusive disease with a history of stroke (8). Evidence of embolic events in other organs was common. Hypertension worsened before biopsy in 21 patients with and without renal artery stenosis. Surgery or angiography definitely or probably contributed to renal failure in 16. Of 12 who underwent surgical revascularization of a renal artery, renal function improved in five, remained stable in five, and worsened in one. Renal function improved in the three patients undergoing dialysis before revascularization, and two were able to discontinue dialysis.

[Endomyocardiopathy and eosinophilia (author's transl)].

Clinical, laboratory, and necropsy findings in a male patient with marked eosinophilia and fatal cardiac failure are reported. Necropsy revealed an obliteration of the left ventricle caused by endomyocardial fibrosis, left ventricle hypertrophy, and white thrombus. There was also found endomyocardial fibrosis and hypertrophy of the right ventricle. Pathogenesis and treatment of endomyocardiopathies are discussed.

[General anaesthesia in microlaryngeal surgery by injection-technique with a modified Carden tube (author's transl)].

A method of general anaesthesia and pulmonary ventilation with automatic intermittent positive pressure for endoscopic laryngeal surgery is described. We have used a technique with a modified Carden tube which gives more freedom to the otolaryngologist. Arterial blood gas studies performed on 10 patients indicated adequacy of ventilation throughout and following the procedure. The special features of this technique are mentioned.

[Changes in intraocular pressure with various concentrations of enflurane during constant conditions of ventilation (author's transl)].

A variety of factors influence intraocular pressure. An increase for example, can be found under conditions of hypoventilation, prohibited ventilation and too light anaesthesia. Some pressure decreasing factors are barbiturates, various inhalation anaesthetics, neuroleptics, and also hyperventilation. In 10 gynaecological patients with normal ophthalmological status, IOP was measured under enflurane anaesthesia by means of a Draeger hand-held applanation tonometer. The neuroleptanaesthesia served as a basis. After anaesthetic conditions were stabilized, concentrations of enflurane ranging from 0.5 to 2.0 vol.% were administered. Under constant ventilation (PECO2) the following parameters were measured: pH, PCO2cap,PO2cap,base excess, minute ventilation, respiratory rate, blood pressure and pulse rate. The concentration of enflurane was measured by gas-chromatography. The IOP was decreased by using enflurane in various concentrations. This decrease is caused by enflurane/itself and is independent of blood pressure changes.

Complex of aspartate carbamoyltransferase from Escherichia coli with its allosteric inhibitor, cytidine triphosphate: electron density at 5.9-angstroms resolution.

Following our earlier determination of the three-dimensional structure of aspartate carbamoyltransferase (EC 2.1.3.2; carbamoylphosphate: L-aspartate carbamoyltransferase) to 5.5-A resolution [S. G. Warren, B. F. P. Edwards, D. R. Evans, D. C. Wiley & W. N. Lipscomb (1973) Proc. Nat. Acad. Sci. USA 70, 1117-1121], we report here, from a different crystal form, the three-dimensional structure at 5.9 A of this enzyme complexed with its allosteric inhibitor, cytidine triphosphate. Location of the major binding site of this inhibitor within each of the six regulatory chains is made secure by comparison of these results with those obtained upon binding of 5-iodocytidine triphosphate to the enzyme. Conformational changes in the aspartate carbamoyltransferase molecule when this inhibitor binds are described briefly at 5.9-A resolution.
