Chronic Paroxysmal Hemicrania: Dissociation of the Pain and Autonomic Features

The case of a woman suffering from chronic paroxysmal hemicrania is presented. Most attacks were unilateral and recurred on the same side. On a few occasions, attacks were observed on the contralateral side. In addition, the patient reported some incomplete attacks on the usually symptomatic side with autonomic phenomena, but without pain. That "partial" attacks would exist has been suspected on theoretical ground. This is, however, the first time such attacks have been reported by a patient. Therefore, a double dissociation of the symptomatology seemed to exist: (1) a side shift of attacks, and (2) incomplete("partial") attacks. These unexpected findings occurred after two indomethacin treatment withdrawals. A possible central and "midline" origin of attacks or an indomethacin after-effect or both are discussed as a likely explanation for such a dissociation of symptoms and signs.

Relations between vasoactive hormones and diastolic function in hypertensive uraemic patients

Background. Arterial hypertension is a significant risk factor for the high rate of cardiovascular disease in chronic uraemic (CU) patients. Any role that hypertension may play in CU patient outcomes assumes added significance. The elevation of some hormonal factors in early clinical stage could represent a valuable marker of cardiac disease in CU. Aim. This study first investigated the role of several hormones on cardiac diastolic properties in CU patients. Moreover, the study investigated the association of hypertension with both diastolic function and release of vasoactive hormones in CU patients. Results. We have reported that the early impairment of diastolic function is correlated with the elevation of both circulating plasma atrial natriuretic factor and endothelin-1 (ET-1) in hypertensive CU patients. Since the effect of ET-1 on diastolic function is still poorly understood, we have investigated also this issue. In eight additional patients with reduced E/A ratio, but without uraemia, hypertension or chronic heart failure, we have showed a high inverse correlation between the values of E/A ratio and ET-1 plasma concentrations. Conclusions. These results strongly suggest that the elevation in ET-1 levels was correlated with diastolic dysfunction in man. This phenomenon may have important pathophysiological implications suggesting the possibility of an early therapeutic approach in these patients.     

Long-term follow-up study of 268 diabetic patients undergoing haemodialysis, with special attention to visual acuity and heterogeneity

We studied the long-term outcome of 268 patients suffering fromdiabetic end-stage renal disease (DM-ESRD) treated with long-termhaemodialysis between 1978 and 1991, with special emphasis onvisual acuity as well as the heterogeneity of DM-ESRD The 50%patient survival on haemodialysis was 60 months. Visual disturbanceswere found in 73.1% (392/536) of eyes at the start of haemodialysis.Chronological assess ment of visual acuity demonstrated thestabilization of visual acuity and 87.1% (364/418) of eyes werestable, 4.8% (20/418) were improved, and 8.1% (34/418) wereaggravated in the long term respectively. The change of visualacuity was frequently seen in the short term, and rapid shiftsof body fluid to correct overhydration induced abrupt changesof glycaemic control as well as retraction of macular oedema.Hence it might be one of the factors affecting rapid changeof visual acuity in the short term. Meanwhile, long-term deterioration of visual acuity resulted from either hyperten sionunresponsive to medical treatment or poor glycaemic control.Some DM-ESRD patients had only background retinopathy at thestart of haemodialysis and these were likely to have the nephroscleroticglomerular lesion. They were old, not nephrotic and had a milddegree of diabetes during the predialysis stage. Thus, DM-ESRDpatients seem to have some heterogeneity in their clinical characteristics,and old DM-ESRD patients with only background retinopathy havethe appearance of diabetic macroangiopathy rather than microangiopathy.

Treatment of chronic lymphocytic leukemia in early and stable phase of the disease: Long-term results of a randomized trial

Abstract: In 1982 the IGCI CLL cooperative group decided to investigate the usefulness of treating, at diagnosis B-cell chronic lymphocytic leukemia (CLL) in early and stable phase of the disease. From January 1982 to December 1986, 148 patients were randomized either to receive immediate treatment with chlorambucil (CLB) or to defer therapy to the time of progression. The early and stable phase of the disease was defined by a total tumor mass (TTM) score < 9, the absence of anemia or thrombocytopenia and a doubling time > 12 months. The main end-point of the study was survival. At the last evaluation in April 1993, after a median follow-up of 75 months, no significant difference was found in overall survival between early vs. deferred treatment patients from every cause of death as well as from death due to CLL-related causes only. The same results were obtained when the patients in more favorable stages, such as Binet stage A and TTM < 4.5, were considered. Interestingly, the incidence of epithelial cancer was similar in the two groups. Early treatment was associated with a significantly better response and a lower progression rate. From this long-term experience, it can be concluded that immediate chemotherapy with CLB is not beneficial for CLL patients in early and stable phase of the disease in terms of survival.
