patients with MSSA infections. There were no significant differences between the two groups in use of mechanical ventilation or haemofiltration/haemodialysis. Cancer and chronic renal failure were more prevalent in MRSA than in MSSA patients. ICU mortality rates were 29.1% and 20.5%, respectively (P < 0.01) and corresponding hospital mortality rates were 36.4% and 27.0% (P < 0.01). Multivariate analysis of hospital mortality for MRSA infection showed an adjusted OR of 1.46 (95% CI 1.03-2.06) (P = 0.03). In ICU patients, MRSA infection is therefore independently associated with an almost 50% higher likelihood of hospital death compared with MSSA infection.
Infection is more common in cirrhotic than in non-cirrhotic ICU patients and more commonly caused by Gram-positive organisms, including MRSA. Infection in patients with cirrhosis was associated with higher mortality rates than in non-cirrhotic patients.
Dysnatraemia is more frequent during the ICU stay than on the day of admission. Dysnatraemia in the ICU - even mild - is an independent predictor of increased hospital mortality.
Study Design: Case series. Objectives: To evaluate the risk of pump-and catheter-related complications of intrathecal drug delivery systems. Setting: Tertiary care center in Switzerland.
Methods:The medical records of all in-and out-patient adults treated at our institution during a 12-year period were reviewed. All patients that had received intrathecal drug therapy via an implanted pump were invited to a structured interview. Results: One hundred patients, representing therapy with 175 implanted pumps and 132 intrathecal catheters over 552 years, participated in the study. During the observation period, 217 surgical procedures (including 100 primary pump implants) and 5863 pump refills were performed. The annual rate for complications requiring surgical measures was 10.5%, with 35% being pump related and 65% being catheter related. The incidence of infections in our patients was 0.7% per year; all infections appeared during the first 3 months after implantation of the first pump. Conclusions: Complication rates of the patients treated in our center, where we have long-term experience with the indication, implantation and continuous care of patients with intrathecal infusion systems, are in the lowest ranges when compared with other published studies. We consider intrathecal testing before implantation, standardized perioperative procedures and consequent long-term care of the patients in a specialized outpatient clinic to be essential factors for the avoidance of complications.
In recent years, new minimally invasive therapies for the treatment of radicular pain associated with contained disc herniation have been introduced. These techniques have changed the field of interventional pain management. In a prospective, nonrandomized case study, we treated patients using the Dekompressor system guided by computed tomography instead of fluoroscopy. Pain scores, analgesic usage, and activities of daily living were assessed via structured telephone interviews 6 and 12 months after the procedure. Sixty-four patients were treated at 76 lumbar levels. Follow-up data after 12 months were obtained for all patients. The average reported pain level as measured by visual analog scale was 7.3 before the procedure and 2.1 after 12 months. Before the procedure, 61 patients (95%) used opioid or nonopioid analgesics regularly; after 1 year, a reduction in analgesic use was seen in 51 patients (80%). None of the patients reported procedure-related complications. When standardized patient selection criteria are used, treatment of patients with radicular pain associated with contained disc herniation using the Dekompressor can be a safe and efficient procedure.
After an initial decrease in resting energy expenditure, body weight and percentage of body fat, these values levelled off during the rehabilitation period. After the end of the rehabilitation period, body weight and body fat mass increased again to the baseline levels, whereas resting energy expenditure decreased further. These results suggest that rehabilitation programmes should focus on adapting to these foreseeable changes.
Although in vitro contracture testing for malignant hyperthermia diagnosis is well standardized, with a relatively high sensitivity and specificity, false test results cannot be excluded and may be associated with serious disabilities for the concerned individuals. In this multicenter study, 4-chloro-m-cresol was evaluated as a new test substance for the in vitro contracture testing. Its use improves the accuracy of in vitro diagnosis of malignant hyperthermia susceptibility.
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.
