Various side effects associated with dimethyl sulfoxide (DMSO) which is used for cryopreservation of bone marrow or peripheral blood progenitor cells (PBPCs) have been reported. Among the central nervous system side effects the epileptic seizures, stroke, transient and temporary leucoencephalopathy, and global amnesia are well known. Herein we report a 52-year-old man who experienced tonic-clonic seizure within minutes after the initiation of DMSO cryopreserved autologous PBPC infusion. Unfortunately, he also developed cardiac arrest and required intubation for ventilation after the seizure. Pathophysiology of acute neurological and cardiac toxicity is unclear, but may also be idiosyncratic. Clinicians should be aware of the toxicity of cryoprotectant agents during PBSC infusion. Determining the risk factors associated with increased DMSO toxicity and taking preventive actions is utmost important.
Between 1990 and 1993, 166 cases underwent cordocentesis and were followed for at least the following 4 weeks in the Prenatal Diagnosis and Therapy Centre of Vienna University. The indications for the procedure were structural malformations in 46.4 per cent of the cases, other high-risk diagnosis in 48.8 per cent, and maternal age over 35 years in only 4.8 per cent. We investigated retrospectively all cases of complications resulting in fetal loss or preterm labour. Abortion, intrauterine fetal death, chorioamnionitis, and preterm delivery occurred in 0.6, 5.4, 0.6 and 9.0 per cent of these cases, respectively, adding up to a total of 26 cases (15.7 per cent). Although this rate looks relatively high, 20 of the 26 cases had already displayed signs implying a complicated prognosis. Neither maternal age, gestational age, number of attempts, nor placental location correlated with fetal loss or preterm delivery. Significantly higher rates of fetal loss or preterm delivery were observed when cordocentesis was performed in cases diagnosed as duodenal/intestinal stenosis or hydrops-ascites-hydrothorax/hygroma colli (P = 0.0488 and P = 0.0005). The frequency of complications did not decrease as the experience of the operators increased.
Objectives: Comorbidities represent a risk factor for adverse events in several critical illnesses. The aim of this study was to identify the relationship between the Charlson Comorbidity Index (CCI) with mortality and length of stay (LOS) in critically ill elderly patients. Methods: A retrospective analysis was made of patients admitted to our tertiary adult intensive care unit (ICU) between January 2015 and January 2016. The impact of comorbidity was evaluated with the CCI. Other required data were retrieved from the patients' follow-up records. Results: The study included a total of 251 patients. The mean age was 78.79 ± 6.70 years. The total mortality rate was 41.0%. The most common cause for admission was sepsis and acute respiratory failure (18.3% vs 18.3%). The median APACHE II score was significantly higher in non-survivors than survivors (31.
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.
