An increase in the intracranial pressure (ICP) might aggravate patient outcomes by inducing neurologic injuries. In patients with increased ICP the optic nerve sheath diameter (ONSD) increases due to its close association with the flow of cerebrospinal fluid. The present study was an attempt to evaluate the efficacy of sonographic ONSD in estimating ICP of patients who are candidates for lumbar puncture (LP). ⋯ The sonographic diameter of the optic nerve sheath might be considered a strong and accurate predicting factor for increased intracranial pressure.

Hypothermia increases clotting time, which is known as hypothermic coagulopathy. However, prothrombin time and activated partial thromboplastin time prolongation associated with therapeutic hypothermia is usually mild and thus, hypothermic coagulopathy is not considered to cause clinically significant bleeding. ⋯ Serious bleeding complications of therapeutic hypothermia has not been reported previously. Herein, we introduce a case of spontaneous brain stem hemorrhage as a complication of therapeutic hypothermia-induced coagulopathy.

In contrast with other opioids, there are few cases of tramadol-related respiratory depression described in the literature, and renal impairment is a proposed risk factor. The aim of this study is to determine the prevalence of and predisposing factors for tramadol-related apnea in patients referred to our center. ⋯ We identified 525 patients with deliberate self-poisoning (359; 68.4%) or abuse (146; 27.8%), and in 114 (21.7%) of these, there was a history of tramadol abuse. Four hundred twenty-nine (81.7%) of patients had acute poisoning and were referred to hospital within 6 hours of ingestion. Nineteen patients (3.6%) experienced apnea and received respiratory support (16; 84.2%) or naloxone administration (3; 15.8%) within 24 hours of ingestion (mean, 7.7 ± 7 hours; range, 1-24 hours). The mean dose ingested by patients experiencing apnea was 2125 ± 1360 mg (range, 200-4600 mg), which was significantly higher than those who did not experience apnea, 1383 ± 1088 mg (range, 100-6000 mg), P < .001. One death occurred in each group, which was significant (P < .001). Renal impairment was not observed in any of the patients who experienced apnea.

Delirium can be associated with cardiac system disorders. Stress plays an important role in the pathogenesis of postoperative delirium. Cortisol is one of the most important stress hormones in humans. We aimed to investigate whether a relation exists between serum cortisol and the degree of delirium after acute coronary syndromes (ACS). ⋯ Delirium was common after ACS, and serum cortisol levels correlated with the degree of delirium and the risk of delirium.

Red cell distribution width (RDW) is associated with mortality in both the general population and in patients with certain diseases. However, the relationship between RDW and mortality in patients with community-acquired pneumonia (CAP) is unknown. The objective of this study was to evaluate the association of RDW with mortality in patients with CAP. ⋯ Red cell distribution width was associated with 30-day mortality, length of hospital stay, and use of vasopressors in hospitalized patients with CAP. The inclusion of RDW improved the prognostic performance of the PSI and CURB-65.
