[Effect on skin and hormonal hyperandrogenic manifestations of an oral estroprogestin association containing ethynilestradiol 30 mg and drospirenone 3 mg]. / Effetto sulle manifestazioni iperandrogeniche a livello cutaneo ed ormonale dell'associazione orale estroprogestinica contenente Etinilestradiolo 30 mg e Drospirenone 3 mg.

AIM: This study evaluated hormonal and skin effects in hyperandrogenic women of an oral estroprogestin (EP) association containing ethynilestradiol 30 mcg plus drospirenone 3 mg. METHODS: Thirty two women with signs and symptoms of hyperandrogenism (seborrhea, acne, increased hair); hormonal assessment (follicle-stimulating hormone, [FSH]; luteinizing hormone, LH; 17-hydroxi-progesterone, 17OHP; androstenedione, A, testosterone, T; dehydroepiandrosterone sulfate, DHEAS; sex hormone binding globulin, [SHBG]; Free Androgen Index [FAI, Tx100/SHBG] was performed before the start of treatment, and after 3 and 6 months of administration of EP. The impact on seborrhea, acne, and hair pattern (Ferriman-Gallwey score) was assessed, and, by non-invasive technique, hydration, water transpiration, and homogeneity of the skin were evaluated. RESULTS: Treatment with this EP for 6 months decreased significantly circulating androgen levels (A, T, DHEAS) and FAI, and increased SHBG levels, also reducing seborrhea, acne and hirsutism. Moreover, EE/DRSP increased hydration and improved overall appearance of skin surface (homogeneity). CONCLUSION: Treatment with EE 30 mcg+DRSP 3 mg improves hormonal pattern and skin appearance in hyperandrogenic patients, potentially with subsequent, beneficial effects on quality of life of these women.

Immunity to extracellular matrix antigens is associated with ultrastructural alterations of the stroma and stratified epithelium basement membrane in the skin of Hashimotos thyroiditis patients.

Employing purified extracellular matrix (ECM) proteins, i.e. type I, III, IV and V collagens (CI, CIII, CIV, CV), laminin (LM) and fibronectin (FN), as antigen sources we detected autoantibodies to conformational and/or denatured ECM antigens among 34 of 50 sera obtained from Hashimotos thyroiditis (HT) patients and 6 of 51 control sera obtained from non-autoimmune thyroid disease patients and healthy donors (HT sera vs. control sera p=4 x 10-9). Reactivity to conformational antigens, mostly due to autoantibodies of the IgG isotype, was observed in 30/50 HT sera and in 6/51 control sera (p=3.5 x 10-7) and was not always concomitant with that to linear antigens, found in 23/50 HT and in 6/51 control sera (p=1.6 x 10-4). Ultrastructural analysis of skin biopsies obtained from 18 HT patients without symptomatic cutaneous diseases revealed defects of the stratified squamous epithelium basement membrane in 11/18, alterations of the stroma in 13/18 and both basement membrane and stromal defects in 9/18. Interestingly, 13/13 (p=0.012) and 9/11 (p=0.012) patients with stromal and basement membrane defects respectively, exhibited serum antibodies to at least one ECM antigen involved in the organization of the altered tissue compartment. Lastly, 10/18 skin biopsies presented immunoglobulin (Ig) and/or complement (C3) deposits along the cutaneous basement membrane zone (BMZ) or in the papillary dermis and 9/10 sera from the same patients simultaneously showed antibodies to at least one ECM antigen involved in the organization of these two skin compartments. Besides, 8/11 HT patients with basement membrane defects exhibited Ig or C3 deposits along the BMZ. Our findings suggest that autoantibodies to ECM molecules might contribute to the development of asymptomatic extra-thyroid skin diseases in HT patients.

[Irritable colon and psychosomatic disease]. / Colon irritabile e psicosomatosi.

The authors, after having considered the close likeness between the collateral clinical picture described by others in regard to the irritable colon syndrome and the outstanding one pointed out by them in many cases of psychosomatic disorders, have analyzed again a large number of personal cases diagnosed as "psychosomatic" in order to find possible relations between these two unwholesome conditions. At the end of their examination, after having ascertained that the "Irritable colon" has not to be considered an isolated disease but a syndrome caused by many factors, hinged on a predisposing condition likely of constitutional nature, the authors remark how it may nest in the folds of a psychosomatic disorder and sometimes be its outbreaking feature. The authors by this way, don't want to conclude identifying the I.C. with a psychosomatic disorder and suggest that in such cases one may take this syndrome as the main manifestation of a condition marked by an impairment of the digestive tract motility inside a psychosomatic disorder with a somatic expression of this apparatus.

[Study of somatosensory evoked potentials in full-term and premature neonates]. / Studio dei potenziali evocati somestesici in neonati a termine e pretermine.

The electrophysiological maturation of both peripheral and 'central' (spinal + superspinal) nervous fibers belonging to peroneal and medial nerves was evaluated within the 1st month of extrauterine life. Thirty-five newborns with different gestational ages (15 FT, 20 PT), have been examined through the SEP technique during percutaneous stimulation of median (wrist and index finger) and peroneal (popliteal fossa) nerves. Recording electrodes were placed at Erb's point, lumbar and cervical spine, scalp sites corresponding to the sensory areas for upper and lower limb. Peripheral conduction velocities were correlated with chronological ages but they did not correlate neither with gestational ages nor with birth weightes. Central conduction velocities correlated with gestational ages. The role of maturation was faster for the former than for the latter.
