After a serial treatment with the fractional CO2 laser, we measured considerably varying wrinkle reduction depending on the area of the face, and the best results were found for the cheeks.
Our results show high patient satisfaction with ablative fractional skin resurfacing, also regarding improved self-esteem and self-satisfaction despite high pre-treatment expectations. Skin-specific quality of life had significantly improved. Thus, this treatment modality can be recommended for patients with photoaged skin wishing to improve skin appearance.
In patients undergoing retrobulbar block placement for eye surgery, 0.3 microg kg(-1) remifentanil over 30 s significantly reduced their reported pain. In addition, remifentanil did not increase the risk of untoward side-effects.
Intraoperative circulatory and pulmonary problems occuring during the repair of femoral neck fractures with cemented hip arthroplasty are a common problem, that cannot be ultimately explained. As a possible reason for this problem is air embolism during the polymerisation of the methylmethacrylat discussed. We started a prospective randomised clinical examination with 72 patients to prove the efficiency of palacos mixed in vacuum, with respect to the reduction of severe cardiovascular complication during endoprosthetic repair of femoral neck fractures. In the control group with 36 patients, surgical repair was performed with palacos mixed conventionally. In the second group (vacuum group), also consisting of 36 patients, surgical repair was performed with palacos mixed in vacuum. Invasive hemodynamic monitoring and transesophageal echocardiography was performed in all cases. In the control group pulmonary embolism occurred echocardiographically in 86% of the cases vs. 14% in the vacuum group. 53% of the control patients--vs. 11% of the vacuum patients--showed clinical complications in form of significant decrease of arterial oxygenation and circulatory insufficiency with the need of catecholamines. Clinical complications occurred in the control group in 80% of the patients--vs. 13.7% in the vacuum group--whose pulmonal arterial pressure was higher than 30 mmHg preoperatively and only in 18.8% of the cases--vs. 7.1% in the vacuum group--with a normal pulmonal arterial pressure. Mortality in the control group amounted to 13.8% in the vacuum group to 2.8%. Through the use of methylmethacrylate mixed in vacuum for surgical repair of femoral neck fractures with cemented hip arthroplasty, the incidence of severe cardiac complications could be reduced significantly. Patients with increased pulmonal arterial pressure have the highest risk for cardiac complications.
We report the results of our study concerning the organisation of operating room (OR) capacity planned 1 year in advance. The use of OR is controlled using 2 global controlling numbers: a) the actual time difference between the expected optimal and previously calculated OR running time and b) the punctuality of starting the first operation in each OR. The focal point of the presented OR management concept is a consensus-oriented decision-making and steering process led by a coordinator who achieves a high degree of acceptance by means of comprehensive transparency. Based on the accepted running time, the optimal productivity of OR's (OP_A(%) can be calculated. In this way an increase of the overall capacity (actual running time) of ORs was from 40% to over 55% was achieved. Nevertheless, enthusiasm and teamwork from all persons involved in the system are vital for success as well as a completely independent operating theatre manager. Using this concept over 90% of the requirements for the new certification catalogue for hospitals in Germany was achieved.
Hepatic rupture after blunt abdominal trauma may lead to severe bleeding, depletion and consumption of clotting factors, with the risk of packing to defer the definitive operation. We report two cases of hepatic rupture after blunt trauma with intrahepatic hematoma and severe intraabdominal bleeding. In both cases the bleeding could be stopped by early intervention with recombinant activated factor VIIa (rFVIIa). In neither case was surgical intervention necessary and after 3 weeks both patients were released without complications. These cases demonstrate that the early therapy with a single dose of rFVIIa before the development of a hemostatic crisis is a therapeutic option in selected cases where surgical therapy of the bleeding is difficult and risky.
An 31-year-old women with a long history of back pain without neurological symptoms underwent a caesarean section during the 36th week of pregnancy with combined spinal-epidural anaesthesia. Indication was the increasingly severe back pain. She delivered a normal healthy boy. On the 3rd day after surgery she developed a discrete sensory cauda equina syndrome on the left side. The interpretation of the magnetic resonance imaging (MRI) was a tumor in the thecal sac extending from the middle of the vertebral body of L-1 to the the superior vertebral plate of L-3. A few days later she underwent a laminectomy under general anaesthesia with resection of an intradural mass adherent to the cauda equina. Pathological review of the surgical specimen revealed a myxopapillary ependymoma WHO grade I. The postoperative course was uncomplicated with preservation of bladder dysfunction but after 4 weeks the bladder function was normalised.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
