From a clinical standpoint, the search for iron deficiency is based upon serum ferritin. However, serumferritin values may be pathologic in other numerous pathological conditions such as inflammation, liver diseases, malignant hematologic disorders, hemolysis, etc. Proteic profile combines the analyze of proteins variations: protein results are converted in percent of normal values referenced for the technique used. ⋯ There was a negative correlation between serum ferritin level and DAT level (r = 0.55; P < 0.0001). In conclusion, an increase of serum transferrin of more than 28% compared to serum albumin on a proteic profile gives a significant benefit for the diagnosis of iron deficiency. This benefit increases when data of both DAT and serum ferritin are associated.

The collagen vascular diseases and vasculitis, in particular, are occasionally associated with chronic, relapsing lower extremity ulcerations. Different mechanisms can induce such ulcerations, and an understanding of the type of ulcerations is important in the differential diagnosis of patients with leg ulcerations in general, and management of these patients in particular. In this review, the authors analyze the various mechanisms of the leg ulcerations in these patients and their treatments: vasculitis, thrombosis, traumatisms, calcinosis, panniculitis, pyoderma gangrenosum, infections, and induced by treatments.

Review Case Reports
[Sweet syndrome and Yersinia enterocolitica infection. 2 cases].
Sweet's syndrome is an acute febrile neutrophilic dermatosis. Although it frequently appears as an idiopathic disorder, it may occur in association, often as presenting sign, with malignancy or more rarely with infections. We report two cases of Sweet's syndrome preceded by digestive infection due to Yersinia enterocolitica, affirmed by significant rises in serum antibody titers. ⋯ Sweet's syndrome is a rare complication of these infections. Treatment with systemic steroids, usually effective, can be replaced by antibiotics with apparently favorable results. The search of an infectious origin should be systematic in cases of Sweet's syndrome that appear to be idiopathic.

Autologous bone marrow transplantation for the treatment of solid tumors in adults remains an uncommon therapeutic approach. The feasibility of such high-dose therapies is clearly proved, especially with the advent of hematopoietic growth factors and the rescue by the peripheral stem cells to reduce the duration of the chemotherapy-induced myeloid aplasia. The question is to exactly define the place of high-dose therapy in the land of solid tumors. ⋯ The results of previous studies are disappointing. Moreover, occult medullary micrometastases involvement is frequent, once again even in limited diseases. However new therapeutic associations, as the ICE regimen (IFM, Carboplatin, VP-16) delivered as single or tandem therapy, have to be studied, especially as early consolidation therapy for the treatment of limited small-cell lung carcinomas.

Fifty-eight consecutive elderly patients (seven men and 51 women, mean age 84 +/- 6) admitted for congestive heart failure were prospectively investigated by doppler echocardiography in order to 1) define the prevalence of cardiac failure with normal left ventricular systolic function, 2) estimate the role of abnormalities of left ventricular filling (diastolic dysfunction), 3) evaluate echodoppler parameters for assessment of diastolic function: ratio of early peak on atrial peak of filling velocities (E/A), mitral deceleration time (MDT) and isovolumic relaxation time (IRT). Of the 58 patients, 32 (55%) had normal left ventricular systolic function and 26 (45%) had systolic dysfunction. ⋯ Sensitivity of clinical data being too low, doppler echocardiography is the easiest noninvasive technique for defining abnormalities of both left ventricular systolic and diastolic function. In the elderly, MDT and IRT are more sensitive parameters than E/A for the diagnosis of diastolic dysfunction.
