Exercise Doppler echocardiography as an aid to clinical decision making in mitral valve disease.

The timing of valve replacement in patients with mitral valve disease, severe resting pulmonary hypertension, and severe symptoms is usually straightforward. However, this may not be true for patients with mild to moderate resting pulmonary pressures and symptoms that are difficult to evaluate. The measurement of hemodynamic parameters with exercise has been useful during cardiac catheterization. The purpose of this study was to evaluate the hemodynamic significance of dyspnea provoked by exercise in patients with mitral valve disease using exercise Doppler echocardiography. Nineteen tests were done in 17 patients (two patients had repeat studies 1 year after the first test). Dyspnea developed in patients during exercise in 11 tests, and the others were limited by fatigue (and angina in one patient). There was a significantly greater increment in pulmonary artery systolic pressure during exercise in the patients who developed dyspnea (24 mm Hg) than in those who did not (15 mm Hg, p = 0.04). The two groups exercised to approximately the same heart rate and blood pressure, but the dyspneic patients had a significantly shorter exercise capacity (p = 0.04). Furthermore, clinical decision making was affected by the test results in 84% (only three tests did not affect patient management) and included a decision to proceed to invasive testing and surgery in seven patients, and a decision to treat the patient medically in nine. In conclusion, exercise Doppler echocardiography is a useful adjunct in the diagnosis and treatment of patients with mitral valve disease and an aid to clinical decision making.

[Syndrome of inappropriate ADH secretion: a late complication of hemopoietic stem cell allograft].

An 11-year old boy with acute lymphoid leukemia underwent umbilical cord stem cell infusion. This was followed at day 15 by the onset of asymptomatic hypotonic isovolemic hyponatremia. The disorder could be attributed to a syndrome of inappropriate ADH secretion (SIADH), most probably related to the massive i.v. induction treatment with cyclophosphamide. The major causes and clinical variants of SIADH are reviewed, with particular emphasis on the complications of chemotherapy in hematological diseases. Worsening of hyponatremia during routine parenteral feeding, as opposed to normalization of plasma Na+ by infusion of hypertonic saline, emphasize the importance of early accurate diagnosis and careful follow-up of these iatrogenic sequelae of stem cell allograft.

Post conception failures in reproduction: infectious diseases and immunitary problems.

The mechanism by which early abortions may be caused by infections disease or immunological problems are discussed by the Authors. Among the first group of causes, syphilitic infections, rubela, viral diseases and others are examined. Immunological problems which may lead to early abortions are then discussed in the more complex context of mother/embryo interactions, examined also on the basis of experimental models. All the hypotheses which may explain refusal of embryo are examined, but the Authors stress the fact that also in proven cases of immunological refusal of pregnancy, the question of the usefulness of immunological therapy remains unanswered.

[Thyroid cancer and Hashimoto's thyroiditis].

In a 45 years old women affected by Hashimoto's thyroiditis appeared a thyroid nodule that at the cytologic and than at the histologic examination proved to be a papillar carcinoma. Concerning this problem the authors make a thorough analysis of the literature. Regarding the possible associations between these two diseases, they observe how there is an extreme discordance of opinions on considering statistically significant the relationship between thyroid cancer and Hashimoto's thyroiditis. They make the hypothesis that the association of these two diseases is not casual: several etiological factors could be considered, but the chronic stimulus of TSH on the thyroid tissue affected by the autoimmune disease and progressively hypofunctioning, could be the main factor responsible for the development of the neoplasia. Then they give some advice to recognise patients at high risk for thyroid carcinoma. The patients at higher risk for thyroid cancer are those that present a single or prevalent nodule; the growth of a nodule on suppressive treatment with levothyroxine is also a negative prognostic index. Patients with an enlarged gland without nodules or with nodular goiter without a prevalent nodule are at low risk for cancer.
