Evaluation of Eye Movement Desensitization and Reprocessing in the management of tinnitus. An observational study.

OBJECTIVES: Tinnitus can induce disabling psychological suffering, requiring an integrative multimodal approach, combining neuromodulation and psychotherapeutic methods. We sought to evaluate the therapeutic efficacy and acceptability of Eye Movement Desensitization and Reprocessing (EMDR) in tinnitus. MATERIALS AND METHODS: This was a single-center prospective non-comparative study. Inclusion criteria comprised: adult patient, with chronic tinnitus, Tinnitus Handicap Inventory (THI) score>17, causing psychological distress motivating active treatment after ineffective "classic" treatment (combining advice, sound therapy and first-line drug treatment), and agreement to EMDR therapy. Therapeutic efficacy was defined by a decrease in THI or Visual Analog Scale (VAS) scores. Treatment acceptability was defined by the rate of included patients who completed therapy. RESULTS: Thirty-eight patients were included. There was a significant reduction of 53.5% in THI score in 78.9% of patients (P<0.0001; 64.8±20.8 before versus 31.8±24.7 after treatment), and of 51% in VAS score in 76.3% of patients (P<0.0001; 7.24±2.12 before versus 3.58±2.03 after treatment). The treatment acceptability was 86.8%. CONCLUSION: EMDR appeared to be an effective alternative that was acceptable to the majority of patients, after failure of "classic" first-line treatment, improving quality of life in tinnitus patients and thus relieving disability.

Sutton's nevus and growth hormone therapy.

Growth hormone (GH) has been suggested to increase the growth of melanocytic nevi and the risk for melanoma in short children treated with substitutive therapy. On the contrary, in GH deficient patients the influence of GH treatment on the appearance and the long-term evolution of Sutton's nevus, a pigmented melanocytic lesion surrounded by a ring (halo) of depigmentation, that usually and progressively involves the nevus, is debated. The aim of this study was to investigate whether GH therapy causes an accelerated growth of Sutton's nevus. In our study, we evaluated 3 children with GH deficiency sharing Sutton's nevus to investigate the relationship between these melanocytic lesions and growth hormone. In case 1 the appearance of the nevus could be induced by hGH therapy. However, the lesion did not change in shape, colour and size even if he entered puberty during substitutive treatment. Moreover, Sutton's nevus is present in case 2, who is prepuberal and not yet treated with hGH. In case 3 Sutton's nevi occurred during GH treatment and after the onset of puberty, but didn't show any long-term change in both the number and size. No clear influence of both GH therapy and sexual steroids on Sutton's nevi was observed.

Serum glucagon concentration and hyperinsulinaemia influence renal haemodynamics and urinary protein loss in normotensive patients with central obesity.

OBJECTIVES: Insulin-resistance syndrome and hyperinsulinaemia are linked with cardiovascular disease (CVD) in the obese population. In particular, cardiovascular risk is more frequent in central obesity and is associated with microalbuminuria (MA). MA and changes of glomerular permeability to proteins in obesity might be related with renal haemodynamic modifications (that is glomerular hyperfiltration). Since glucagon is physiologically involved in renal haemodynamic regulation, the purpose of this study was to examine whether changes of circulating glucagon levels might haemodynamically induce MA and proteinuria in patients with central obesity. SUBJECTS: Forty normotensive obese out-patients, 22 with central (CO group) and 18 with peripheral (PO group) body fat distribution and 11 healthy subjects. MEASUREMENTS: Serum insulin and glucagon concentrations (fasting and after oral glucose tolerance test (OGTT)) by radio immuno assay (RIA); glomerular filtration rate (GFR, isotopic); total clearances and urinary excretion rates of albumin (AER), IgG (IgGER) and alpha1 microglobulin (computerized immunonephelometry). RESULTS: GFR and insulin concentrations (fasting and during OGTT) were higher in the CO than the PO group. Fasting glucagon concentrations were increased, and not physiologically suppressed during OGTT in patients with CO (fasting, P<0.05; OGTT 60 and 120 min, P<0.001 vs PO group). Moreover, glucagon concentrations were significantly correlated with GFR in the CO group (fasting, r=0.49, P<0.05; 60 min after OGTT, r=0.58, P<0.01); whereas no correlations were found in the PO group. Higher AER (P<0.001), IgGER (P<0.001) and alpha1 microglobulin (P<0.05) urinary concentrations were found in patients with CO than in the PO group. CONCLUSIONS: The increase of serum glucagon concentrations may be associated with the enhancement of GFR in patients with central obesity. Glomerular hyperfiltration might influence the development of MA and of proteinuria by means of a haemodynamic mechanism so contributing to increase the risk of renal microvascular complications and of CVD in central obesity.

A 3-19-year follow-up study on diabetic retinopathy in patients diagnosed in childhood and treated with conventional therapy.

Few data are available from follow-up studies on diabetic retinopathy in patients diagnosed with insulin-dependent (Type 1) diabetes mellitus in childhood and treated with conventional therapy. We report the results of conventional insulin therapy on development of diabetic retinopathy in 100 children and adolescents (47 females and 53 males), aged 8.3 +/- 3.5 (1.2-16.4) years at diagnosis of disease. Oral or intravenous fluorescein angiography was performed during a 3-19 year follow-up in all patients. Retinopathy was staged according to the criteria of the Italian Society of Diabetology (SID). During follow-up, retinopathy was observed in 28 patients (28%). At the end of follow-up, retinopathy was present in 23 patients and had disappeared in 5. Life-table analysis showed a median disease-free interval of 10.8 years. At 10 years from diagnosis the percentage of patients free of retinopathy was 66%. Poor metabolic control, age, and degree of pubertal development at diagnosis were the most important risk factors.
