Focal epileptic seizures, electroencephalography and outcome of sepsis associated encephalopathy-A pilot study.

OBJECTIVES: Sepsis associated encephalopathy (SAE) represents a diffuse and/or multifactorial cerebral dysfunction during response to systemic infection. Study aim was to compare clinical and electroencephalogram (EEG) characteristics and intrahospital survival rate among SAE patients. PATIENTS AND METHODS: A prospective study, during 42 months' period, included 39 SAE patients assigned in two groups according the outcome (survival: 19, and death: 20 patients). All the patients' features were registered: demography, neurological status, infection type, seizure appearance, brain computerized tomography (CT), EEG, EEG reactivity, Glasgow Coma Score (GCS) and Acute Physiology and Chronic Health Evaluation II (APACHE II) Score. The analysis included EEGs obtained during patients' consciousness change (improvement or deterioration) and the level of consciousness during and at the end of hospitalization. RESULTS: SAE was detected in 29.5% of patients with encephalopathy (2.8% of all patients hospitalized). Patients with lethal outcome were more likely to be female (p=0.0011), to have focal seizures (p=0.034), lower values of GCS during hospitalization (p<0.05) and longer lasting nosocomial infections (p=0.029). At the time of clinical exacerbation, patients were more likely to have suppression on EEG and less likely theta activity. Delta waves, TW waves and suppression of EEG activity were the most common findings 24h prior to death (p=0.0004). The lack of EEG reactivity was associated with death (p=0.00043). CONCLUSION: Presence of focal seizures, EEG suppression at the time of exacerbation in SAE elderly patients, particularly women, with longer infection duration and lower values of GCS, is associated with intrahospital death.

Do women benefit more from systemic thrombolysis in acute ischemic stroke? A Serbian experience with thrombolysis in ischemic stroke (SETIS) study.

OBJECTIVE: The female sex is associated with increased stroke severity and relatively poor functional recovery. Several studies have demonstrated that women with stroke benefit more from intravenous thrombolysis compared with men, while others found the nullification of gender effect among women treated with recombinant tissue plasminogen activator (rtPA). The purpose of our study was to determine any gender differences in the efficacy and safety of systemic thrombolysis among patients with acute ischemic stroke in Serbia. METHODS: Data were from the Serbian experience with intravenous thrombolysis in ischemic stroke (SETIS) study, a prospective, ongoing, multicenter, open, and observational study in Serbia of all patients who have received rtPA for acute ischemic stroke. We analyzed sex differences in the baseline characteristics, functional outcome and treatment complications. RESULTS: Among 60 women and 96 men with stroke and treated with intravenous thrombolysis, we found that at day 90, no significant sex differences in excellent functional outcome (50.9% of women vs. 57.0% of men, p=0.5), favorable functional outcome (61.4% of women vs. 68.8% of men, p=0.38) or death (8.8% of women vs. 12.9% of men, p=0.60). These results were constant even after adjustments for age, severity of basal neurological deficit and onset to treatment time. CONCLUSION: There were no sex differences in functional outcome at 90 days after the stroke among patients treated with IV rtPA. This finding might confirm that thrombolytic therapy nullifies usual sex differences in stroke outcome and suggests that women with stroke may benefit more from rtPA treatment.

Cytogenetic analyses reveal "atypical cells" in the peritoneal dialysis effluent.

Cytogenetic analyses were performed on dividing cells from the peritoneal effluent of 26 patients undergoing chronic peritoneal dialysis (CPD). Numerical and structural abnormalities of karyotype served as the diagnostic criteria for "atypical cells." The following cytogenetic abnormalities were observed in 7 patients: hyperdiploidy (in 6 patients), hypodiploidy (in 2 patients), and marker chromosomes (in 2 patients). In 3 patients more than one chromosome abnormality was present. Dividing cells with normal mitoses were observed in 11 patients, while in the remaining 8 patients no dividing cells could be found. There were no differences in age, sex, duration of dialysis, and peritonitis incidence between patients with pathological mitoses and those without it. The question whether this unexpected finding is a consequence of immunosuppressed uremic status, dialysis procedure, or some other factor remains to be elucidated.

["One and a half syndrome" caused by lateral pontine haemorrhage]. / "Sindrom jedan i po" prouzrokovan lateralnom pontinom hemoragijom.

"One and a half syndrome" is an internuclear ophthalmoplegia combined with lateral gaze palsy on the same side. It is caused by ipsilateral lesion of the caudal part of pontine dorsal tegmentum - medial longitudinal fasciculus and paramedian pontine reticular formation or/and abducens nucleus. Usually it is of vascular origin and it can be a sign of lateral pontine haemorrhage. We described a patient with "one and a half syndrome" caused by spontaneous hypertensive hemorrhage in the lateral pontine legmentum which was visualised by brain CT scanning.
