Relationship between P-wave dispersion and effective hemodialysis in chronic hemodialysis patients

To investigate whether or not P-wave dispersion [PWD] can be used as a good indicator of effective hemodialysis. The study included 35 patients [20 males, 15 females, mean age 61 +/- 10 years] who regularly received hemodialysis treatment for chronic renal failure. Following hemodialysis, the patients whose hemodynamic parameters were preserved and who reached dry body weight were included. Twelve-lead resting electrocardiogram [ECG] at a speed of 25-50 mm/s, the value of total body fluid [TBF] and bioelectric impedance using bipedal bioelectric impedance equipment were obtained before and immediately after hemodialysis. Blood samples were also taken for the assessment of blood electrolytes, urea and creatinine. PWD was defined as the difference between the maximum and minimum P-wave duration calculated on a standard 12-lead ECG before and after dialysis. The following parameters were obtained before and after hemodialysis: blood pressure 132 +/- 21 vs. 130 +/- 10 mm Hg [p > 0.05], TBF 33.9 +/- 6 vs. 32 +/- 5.6 liters [p = 0.001], impedance 499 +/- 110 vs. 596 +/- 136 omega [p = 0.001], P-max 103.1 +/- 8.9 vs. 106.3 +/- 12.7 ms [p > 0.05], P-min 70.2 +/- 11 vs. 72.5 +/- 7.9 ms [p > 0.05], PWD 32.2 +/- 11.9 vs. 33.8 +/- 13.4 ms [p > 0.05]. Although statistically significant decreases were observed in urea and creatinine levels after hemodialysis, no such changes were observed in blood electrolytes. The P-max and PWD did not change significantly after hemodialysis, hence these two parameters can be used as an indicator of effective hemodialysis

Comorbidity of constrictive pericarditis and hemophilia A

To report a case of comorbidity of constrictive pericarditis and hemophilia A. Clinical Presentation and Intervention: A 21-year-old male with hemophilia A was referred to our clinic and was examined with the subsequent evaluation of shortness of breath, leg edema and ascites. Clinical and laboratory examinations were performed. The results were consistent with constrictive pericarditis [CP], and the symptoms were completely relieved following institution of medical therapy. Because hemophilia A and pericarditis may be coincidentally present clinical conditions, avoidance of surgical procedures in hemophilic patients is preferable unless the resolution of the symptoms of pericarditis cannot be effected by medical therapy
