Robot assisted laparoscopic excision of a paraganglioma: new therapeutic approach

The Paraganglioma is the most common extra-adrenal pheochromocytoma arising from neural crest (1) (It will better to write: The paraganglioma is an extra-adrenal pheocromocytoma arising from the neural crest. 10% of pheocromocytomas are extra-adrenal and can arise form chromaffin tissue derived from primitive neuroectoderm). Minimally invasive techniques allow surgeons to perform the procedure without wide exposure and mobilization of intra abdominal organs. To our knowledge we present the third case of robotic excision of a retroperitoneal paraganglioma (2,3).

Evaluation of the body composition and fat distribution in long-term users of hormone replacement therapy.

The aim of the study was to evaluate the body composition and fat distribution in long-term users of hormonal replacement therapy (HRT). 18 healthy menopausal women, long-term users of HRT (transdermal estradiol 50 microg continuously administered and 10 mg/day of medroxyprogesterone acetate for 12 days/month) and 18 healthy menopausal women, who had never used HRT were included in the study. Age, menopausal age, parity, weight and height (body mass index, weight/height2), and lifestyle habits were similar. Waist and hip circumference, body composition and waist/hip ratio were measured and the results were analyzed. No significant difference was demonstrated in fat and water percentage, and waist/hip ratio. Nevertheless, the waist circumference of long-term HRT users was significantly lower than that of non-users. In conclusion, abdominal fat in long-term HRT users is lower than that of non-users of similar age, menopausal age and body mass index.

[Hormone substitution therapy. Side-effects and compliance of various therapeutic regimens]. / Terapia ormonale sostitutiva. Effetti collaterali e compliance di differenti regimi terapeutici.

BACKGROUND: The aim of this study is to evaluate the tolerability and long-term compliance of four Estrogen Progestin treatments (HRT) for menopause. METHODS: One hundred and ten symptomatic menopausal women were divided into four groups according to therapeutic regimens: A) Estradiol (E2) transdermal treatment 50 micrograms (TTS 50) continuously administered (cont.) plus Medroxyprogesterone Acetate (MPA) 10 mg/die for twelve days a month: 35 women. B) Conjugated Equine Estrogens (CEE) 0.625 mg/die cont. plus MPA for twelve days a month: 25 women. C) Estradiol transdermal 50 micrograms (cont.) plus MPA 2.5 mg/die cont.: 26 women. D) CEE 0.625 mg/die cont. plus MPA 2.5 mg/die cont.: 24 women. RESULTS: Menopausal symptoms were significantly reduced with all treatments. During the first year group C and D patients showed irregular bleeding (group C: 46%, group D: 61%). After 24 months the bleeding frequency was reduced (group C: 11%, group D: 13%). Mastodynia was the more frequent side-effect in particular among women who were utilizing cont.comb. regimens. The total percentage of drop out (D.O.) after 2 years was more than 30% (Group A: 31%, Group B: 33%, Group C: 39%, Group D: 35%). The most frequent reasons for abandoning HRT (79% of all DO) were not linked to therapy side-effects. 19% of DO switched to other hormonal regimens.

[Effect of GnRH analogues on bone density in the vertebral column and the femur]. / Effetto degli analoghi del GnRH sulla densità ossea della colonna e del femore.

The objective of this study was to evaluate the effect on vertebral and femural bone density of the gonadotropin-releasing hormone (GnRH) analog administration. The changes in mineral bone density after 6 months discontinuation of the GnRH analog treatment were also measured. Forty-three premenopausal women with regular cycles and suffering from uterine myomatosis have been selected for the study. Twenty-eight women (group A) were treated with Goserelin 3.2 mg given as a depot every 28 days for 6 months. Fifteen women were treated with 10 mg of medroxyprogesterone acetate (MPA) from day 16 to day 25 of each month for 6 months. Vertebral and femural bone density was measured (by Hologic QDR-X 1000) just before the start of the study, at 6 months of treatment and at 12 months (after 6 months of discontinuation treatment). Significant loss of vertebral bone density was demonstrated in women treated with GnRH analog. After six months of treatment discontinuation bone mineral density did not recover the pretreatment values. Bone femural density showed a not significant decrease in the GnRH analog group. In our experience, the treatment with GnRH analog in premenopausal women induces a reduction in lumbar bone density that is not reversible after the treatment withdrawal; for this reason it would be safe to add at the GnRH analog a therapy which can prevent the bone loss.
