Immediate loading of mandibular implants in compromised patients: preliminary results.

To minimize the number of implant surgical procedures, a total of 72 single-stage, transgingival Frialoc implants (Friadent) were placed in the mandibles of 18 patients who required implant restoration. The patients' ability to undergo surgical implant treatment was restricted because of either poor general medical health or psychologic conditions. All implants were immediately loaded with a bar-retained overdenture.

Peritoneal dialysate fill-volumes and hernia development in a cohort of peritoneal dialysis patients.

A retrospective case control study was performed on a cohort of 244 peritoneal dialysis patients followed over 5 years to determine whether dialysate fill-volume was associated with hernia development. The laboratory and clinical parameters of patients who developed hernias during this time period were compared with those of patients who did not develop hernias. Information on 27 patients who developed hernias was compared with that on 217 patients who did not develop hernias.

[Importance of 24-hour blood pressure monitoring in secondary hypertension].

A typical diurnal variation in blood pressure is observed in patients with essential hypertension. Attenuation or lack of circadian periodicity might be expected in patients with secondary hypertension. Therefore, non invasive ambulatory blood-pressure monitoring was performed in 172 patients with secondary hypertension and in 201 patients with essential hypertension.

Comparison of the antihypertensive efficiency of nitrendipine, metoprolol, mepindolol and enalapril using ambulatory 24-hour blood pressure monitoring.

In a randomized 6-month study of 201 patients, the antihypertensive efficiency of the calcium antagonist nitrendipine, the beta 1-selective blocker metoprolol, mepindolol, the beta blocker with intrinsic activity and the angiotensin-converting enzyme inhibitor enalapril were compared as monitored by 24-hour ambulatory blood pressure (BP) measurements. The study was designed so that a comparable decrease in casual BP values was obtained with all 4 drugs. If normotension was not achieved with monotherapy, a diuretic also was administered.

[Plasma endothelin in normal probands and patients with nephrologic-rheumatologic and cardiovascular diseases].

Plasma concentrations of the recently isolated potent vasoconstrictory peptide endothelin were measured in 382 patients. The investigations were performed by means of a sensitive radioimmunoassay specific for Endothelin-1, 2. The results from 110 healthy volunteers displayed a normal range of 44.
