Overhydration as a modifiable cardiovascular risk factor in patients undergoing hemodialysis.

Introduction: Cardiovascular mortality in patients with end-stage renal disease (ESRD) remains high despite advances in dialysis techniques. This can be attributed to several traditional and nontraditional risk factors. Overhydration seems to be one of the promising cardiovascular risk factors that could be targeted to improve survival.

Frequency of Complete Atrioventricular Block Complicating ST-Elevation Myocardial Infarction in Patients Undergoing Primary Percutaneous Coronary Intervention.

Objectives: ST-segment elevation myocardial infarction (STEMI) can be associated with many conduction disturbances including complete atrioventricular block (CAVB). CAVB complicating STEMI resulted in an increased mortality before the modern era of primary percutaneous coronary intervention (PCI). The aim of this study was to ascertain the rate and risk factors for CAVB in STEMI patients undergoing rapid reperfusion with PCI.

N‑terminal pro‑B-type natriuretic peptide as a marker of hypervolemia and predictor of increased mortality in patients on hemodialysis.

Introduction: N‑terminal pro‑B‑type natriuretic peptide (NT‑proBNP) is an established biomarker of heart failure in the general population. However, its diagnostic value is unclear in hemodialysis (HD) patients owing to renal insufficiency.

Objectives: The aim of the study was to establish the usefulness of NT‑proBNP for hydration assessment and the relation of NT‑proBNP to the nutritional state and prognosis of survival.

Stenoses of the salivary ducts-sialendoscopy based diagnosis and treatment.

Our aim was to analyse the nature of a sialendoscopy-based classification and present its use in the treatment of stenoses of Wharton's and Stensen's ducts. The classification of stenoses of Wharton's duct has not been published before. We did 133 sialendoscopies in 114 patients who presented with possible obstruction of the ducts to the tertiary centre for ENT at the University Department in Poznań.

Clinical utility of ambulatory EEG monitoring.

Our initial clinical experiences with the "Oxford" ambulatory nontelemetry EEG monitoring shows that it is a useful and economical device for monitoring EEG and EKG activity in patients in a normal environment. Careful selection of the patient with possible seizure disorder and emphasis on temporal lobe recordings may give a higher degree of diagnostic yield in questionable cases of seizure. Further investigations utilizing this modality (ambulatory EEG monitoring) appears to be fully warranted.

Brain stem auditory evoked responses in clinical practice.

A relatively new noninvasive technique for the diagnosis of abnormalities affecting the central nervous system is presented. It is especially useful in patients with acoustic neuroma, brain stem disorder such as tumors of the posterior fossa with neuraxis impingement, as well as demyelinating disorders such as multiple sclerosis. It is certainly useful in the verification of neurologic normalcy in patients complaining of dizziness and vertigo.

Paroxysmal beta activity in the pediatric electroencephalogram.

A total of 5,401 electroencephalograms performed in the Seizure Unit at Children's Hospital Medical Center over a 12-month period were analyzed for the presence of paroxysmal beta activity. Nine examples were found in patients under the age of 10 years, each of whom had a clinical seizure disorder. Seven patients showed abnormalities such as tumor, cerebral dysgenesis, or hydrocephalus on CAT scans or skull roentgenograms.

Neurologic sequelae of experimental febrile convulsions.

A study was designed to investigate the effects of experimentally produced hyperthermic seizures on the brain of the developing rat. Severty-nine newborn Sprague-Dawley white rats were divided into five groups and exposed to one of the following: Nonseizure-producing hyperthermia at 5 or 15 days (febrile controls), seizure-producing hyperthermia at 5 or 15 days, or no hyperthermia (afebrile controls). As the animals matured, seven developmental reflexes were tested and there were no differences found among the five groups in the ages at which these reflexes were acquired.
