    Diabetic muscle infraction: An unusual cause of muscle pain in a diabetic patient on hemodialysis
    (Springer, 2005) Sahin, Ibrahim; Taskapan, Cagatay; Taskapan, Hulya; Baysal, Tamer; Bentli, Recep; Tekes, Selda; Kosar, Feridun
    Diabetic muscle infarction (DMI) is a rare, painful and potentially serious complication in patients with poorly controlled diabetes mellitus and frequently misdiagnosed clinically as abscess, neoplasm, or myositis. A 36-year-old diabetic woman referred to our clinic with severe pain in the left anteromedial thigh. She had a 15-year history of Type 2 diabetes mellitus (DM). She was complicated by diabetic nephropathy and requiring hemodialysis. She had first noticed pain and swelling in her left thigh after a minimal trauma for 2 days prior to presentation. Clinical and laboratory evaluation, and muscle biopsy revealed the diagnosis of muscle infarctions. She did no respond to the conservative therapy. Pain and swelling in her thigh worsened progressively. She underwent surgical debridment and then, her clinical status improved. We describe the characteristic clinical and pathologic findings and the course of the illness with emphasis on the importance of recognition of the syndrome so that unnecessary investigation and overzealous therapy can be avoided.

    P-wave duration and dispersion in obese subjects
    (Blackwell Publishing, 2008) Kosar, Feridun; Aksoy, Yueksel; Ari, Fahri; Keskin, Lezzan; Sahin, Ibrahim
    Background: Although previous studies have documented a variety of electrocardiogram (ECG) abnormalities in obesity, P-wave alterations, which represent an increased risk for atrial arrhythmia, have not been studied very well in these patients. The aim of the present study was to evaluate P-wave duration and P dispersion (Pd) in obese subjects, and to investigate the relationship between P-wave measurements, and the clinical and echocardiographic variables. Methods: The study population consisted of 52 obese and 30 normal weight control subjects. P-wave duration and P-wave dispersion were calculated on the 12-lead ECG. As echocardiographic variables, left atrial diameter (LAD), left ventricular end-diastolic, and end-systolic diameters (LVDD and LVSD), left ventricular ejection fraction (LVEF), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), and left ventricular mass (LVM) of the obese and the control subjects were measured by means of transthoracic echocardiography. Results: There were statistically significant differences between obese and controls as regards to Pmax (maximum P-wave duration) and Pd (P dispersion) (P < 0.001 and P < 0.001, respectively). Pmin (minimum P wave duration) was similar in both groups. Correlation analysis showed that Pd in the obese patients was related to any the clinical and echocardiographic parameters including BMI, LAD, LVDD, IVST, LVPWT, and LVM. Conclusion: Our data suggest that obesity affects P-wave dispersion and duration, and changes in P dispersion may be closely related to the clinical and the echocardiographic parameters such as BMI, LAD, IVST, LVPWT, and LVM.
