Randomized Controlled Trial Comparative Study Clinical Trial[Double-blind comparative study of the effectiveness and tolerance of 900 mg dexibuprofen and 150 mg diclofenac sodium in patients with painful gonarthrosis].
In this randomized double-blind, parallel-group study the efficacy of 300 mg oral dexibuprofen three times daily and 50 mg oral diclofenac sodium three times daily was tested for equivalence in 110 patients with painful osteoarthritis of the knee. During the 15-day treatment period the functional index for knee osteoarthritis according to Lequesne was improved under dexibuprofen by a mean of 7.4 and by a mean of 7.3 under treatment with diclofenac sodium. ⋯ The descriptive analysis of secondary criteria such as intensity of pain, rest pain, pain at beginning, nocturnal pain, tenderness, restriction of movement, handicap, subjective estimation of disease progression, as well as global judgement of efficacy and tolerance by investigator and patient confirm equivalence of both preparations. The pooled analysis of all parameters, tolerability included, by a Mann-Whitney-statistic of 0.520 with the lower boundary of the 95% confidence interval of 0.467 shows equivalence of both drugs with a trend to superiority of dexibuprofen due to its better tolerability. 7.3% of the patients on dexibuprofen and 14.5% of the patients on diclofenac sodium dropped out because of side-effects.

Randomized Controlled Trial Comparative Study Clinical TrialThe management of pneumothorax with the thoracic vent versus conventional intercostal tube drainage.
The thoracic vent is a new minimally invasive device for the treatment of spontaneous and iatrogenic pneumothorax. It consists of a polyurethane catheter connected to a plastic chamber containing a one-way valve. As there is no need to connect the thoracic vent to an underwater seal device, immobilization and hospitalization can be avoided. ⋯ Hence, we have performed a randomized study comparing the treatment of pneumothorax by means of the thoracic vent versus conventional intercostal tube drainage in 30 patients, including some with tension pneumothorax. 17 patients were treated with the thoracic vent, 13 with conventional intercostal tube drainage. We found no significant differences in the rate of reexpansion and rate of complications between the group treated with the thoracic vent and the group treated with intercostal tube drainage, but the patients treated with the thoracic vent needed significantly less analgesics. 70% of the patients treated with the thoracic vent were successfully managed on an outpatient basis. All patients treated with intercostal tube drainage were hospitalised; duration of inpatient-therapy was 8 +/- 6.2 days (mean +/- SD).

Randomized Controlled Trial Comparative Study Clinical TrialSafety and efficacy of increasing dosages of glycyl-glutamine for total parenteral nutrition in polytrauma patients.
Supplementation of parenteral nutrition with glutamine (GLN) has been suggested to improve the efficacy of nutritional support by stimulating protein synthesis and improving immunocompetence. In the present study we investigated the impact of infusing the dipeptide glycyl-glutamine (GLY-GLN) at increasing dosages on plasma amino acid concentrations in patients with polytrauma. Nine polytraumatized patients were randomly assigned according their age and their trauma score to three experimental groups. ⋯ We conclude from this first available dose finding study on glutamine-containing dipeptides that in polytraumatized patients infusion of 570 mg/kg/day of GLY-GLN (corresponding to 28 g glutamine or 40 g dipeptide/70 kg, respectively) is necessary to induce a sustained effect on plasma glutamine concentrations. No pathological accumulation of free glycine or of the dipeptide was seen with any of the three dosage steps of GLY-GLN. Thus, the administration of even high doses of GLY-GLN is feasible and safe in patients with polytrauma and is not associated with any relevant renal substrate loss.

Randomized Controlled Trial Clinical Trial[Comparison of an oxygen-conserving module "Oxytron" and the reservoir cannula "Oxymizer Pendant" with continuous oxygen administration via nasal prong in hypoxemic patients].
High costs involved in administering continuous long-term oxygen therapy to patients with chronic lung diseases and limited portability of oxygen sources stimulated research into and development of oxygen conserving devices. Oxytron (Weinmann, Hamburg) is a new electronic demand oxygen delivery system which limits oxygen flow to the early phase of inspiration. The reservoir cannula Oxymizer Pendant (Chad-Therapeutics Inc.) is a nasal prong system incorporating a pendant reservoir which stores oxygen during expiration and delivers it as a bolus at the onset of inspiration. ⋯ With the reservoir cannula oxygen saving was most evident at low oxygen flows: 29.3, 19.4 and 4.7% less oxygen was required than with continuous flow at 2, 3 and 41/min. Individual patient acceptance of various drug delivery systems and response to therapy should be considered when prescribing home oxygen therapy. The use of oxygen saving techniques could result in a substantial cost saving and greater mobility may help to improve compliance in patients requiring continuous oxygen therapy.
