Thanks to Dr. Daniel J. Brotman of the Cleveland Clinic Foundation for pointing out an error in the confidence interval for sensitivity in “Platelet count/spleen diameter ratio predicted the presence of esophageal varices in liver cirrhosis” (1). The correct values appear in the Table. Operating characteristics of platelet count/spleen diameter ratio (cutpoint ≤ 909 for a positive diagnosis) fo...

A total of 56 Staphylococcus aureus isolates incubated for 2 h in the presence or absence of oxacillin were analyzed by flow cytometry after labeling with an S. aureus-specific peptide nucleic acid (PNA) probe. Two defined ratios, the paired signal count ratio (PSCR) and the gate signal count ratio (GSCR), differentiated methicillin-resistant S. aureus (MRSA) and methicillin-susceptible S. aure...

Objective: The value of head-up tilt test (HUTT) for differential diagnosis epilepsy and the autonomic nervous system functions in
 epileptic children using heart rate variability (HRV) are studied.
 Patients Methods: study group consisted 16 with idiopatic/criptogenic 12 controls. Heart rate, PR
 interval, corrected QT (QTc) QTc dispersion were calculated 12-lead electrocardiogr...
