Effective management of marked lymphedema of the leg.

BACKGROUND: Several conservative and surgical treatment methods have been demonstrated to be useful in the management of lymphedema. METHODS: In a patient with an enormous lymphedema of the leg, we first used complex decongestive physiotherapy as proposed by Földi et al. in 1989, and then followed it with surgery. RESULTS: Satisfactory results were obtained in a short period of time and were maintained during the 2-year follow-up. CONCLUSIONS: We recommend a combined medical, surgical, and physiotherapeutic approach in patients with marked lymphedema.

[Malignant diphtheric myocarditis].

PURPOSE: In the current study we analyzed clinical evolution and therapeutic aspects of malignant diphtheric myocarditis. METHODS: Fourteen patients with primary diagnosis of diphtheria were prospectively evaluated. Cardiac involvement was detected after 11.5 (mean) days. The diagnosis of diphtheric myocarditis was done in clinical basis. RESULTS: Seven (50%) patients died. Cardiac failure was a common finding in all cases. Complete A-V block was identified in eight (57%) patients. Temporary pacemaker was implanted in 10 cases, six of them died due to myocardial failure. Definitive pacemaker was necessary in two patients with persistent complete A-V block after one-month follow-up. One patient with atrial fibrillation died with sepsis. Respiratory infection was the commonest extracardiac complication (six cases) and two patients developed Guillain-Barré syndrome. We also identified neurologic, renal and adrenal complications. CONCLUSION: Cardiac rhythm disturbances in diphtheric myocarditis are associated with high probability of necessity of temporary pacemaker and high mortality. Definitive pacemaker can be implanted in persistent complete A-V block.

[Diastolic dysfunction in patients with chronic kidney failure on a hemodialysis program].

OBJECTIVE: The aim of this study was to analyse different ultrasound parameters for the assessment of isolated left ventricular diastolic dysfunction (LVDD) in patients with chronic renal failure (CRF) on periodic hemodialysis (HD), comparing pulsed wave Doppler with pulsed tissue Doppler. MATERIALS AND METHODS: Forty-seven patients with CRF on HD (61% were male; mean age was 51.0 +/- 16.5 years, mean HD time--3.7 +/- 3.8 years, 38% had hypertension, 17% had diabetes) were studied by echocardiography (bidimensional, M-Mode, flow pulsed Doppler and tissue Doppler imaging). All patients had symptoms of left heart failure-class II NYHA, were in sinus rhythm and had no symptoms of ischemic heart disease. The presence of abnormal LV regional contractility was the exclusion criteria. According to their mitral inflow profile Doppler characteristics, patients were included in two groups: Group A (E/A > 1; n = 21) and B (E/A < 1; n = 26). We compared: LV dimensions and function, left atrial (LA) dimension. Gaasch index, LV mass index. E and A wave velocities (in flow pulsatile Doppler and tissue Doppler). E/N ratio in tissue Doppler, isovolumetric relaxation time (IVRT) and deceleration time (DT). RESULTS: There were no significant differences in the prevalence of age > or = 65 years male sex, hypertension or diabetes between group A and B patients, and almost all patients were on hemodialytic treatment for more than one year (81% vs 85%: NS). LV hypertrophy was present in almost all group A and B patients (A--95% vs B--85.5%; NS). Group A, compared with group B, had a difference in the Gaasch index (2.45 +/- 0.3 vs 2.08 +/- 0.4; p < 0.05), E wave velocity in flow pulsatile Doppler and tissue Doppler (cm/sec) (110 +/- 27 vs 62 +/- 20; p < 0.001 and 41 +/- 15 vs 28.5 +/- 16; p < 0.05), E/A ratio in tissue Doppler (1.3 +/- 0.4 vs 0.8 +/- 0.3; p < 0.001). IVRT (msec) (80.7 +/- 15.2 vs 113.5 +/- 28.3; p < 0.001) and DT (msec) (189.7 +/- 24 vs 278.2 +/- 17.9; p < 0.001). According to the E'/A' ratio in tissue Doppler, group A patients were divided in another two groups: E'/A' > 1 (13/21--62%) and < 1 (8/21--38%) and a significantly longer IVRT (75.8 +/- 9.3 vs 100.9 +/- 3.2; p < 0.001) and DT (178 +/- 15 vs 240 +/- 20; p < 0.001) and a greater LA dimension (37.6 +/- 6.9 vs 44.6 +/- 6.9; p < 0.05) were found. CONCLUSIONS: Pulsed wave Doppler is the most useful non invasive method for assessment of global diastolic dysfunction. In our study, 17% of the patients had E/A < 1 only in the tissue Doppler study. These patients probably had a pseudonormal mitral pattern.
