Hypoactive sexual desire disorder in postmenopausal women.

Decreases in sex hormone levels with menopause may bring about a number of consequences in women's general health and sexual well-being, especially when levels decline suddenly and prematurely, as in surgical menopause. In addition to the well-established role of estrogens in preserving the biological basis of sexual response, there is emerging evidence that androgens are significant independent determinants affecting sexual desire, activity and satisfaction, as well as mood, energy and other components of women's health. Hypoactive sexual desire disorder (HSDD), a persistent absence of sexual fantasies or thoughts and/or desire for and receptivity to sexual activity that causes personal distress, is experienced by some postmenopausal women. Even though conventional hormone therapy with estrogens or estrogens and progestogens may be effective for vaginal atrophy, increasing vaginal lubrication and reducing dyspareunia, it has not been shown to consistently increase sexual desire or activity and many women with sexual dysfunction remain unresponsive. Several recent, large, phase III studies have shown that the addition of transdermal testosterone to conventional hormone therapy can be helpful in surgically menopausal women presenting with HSDD. After 24 weeks of treatment in these studies, testosterone-treated women experienced significantly greater increases in satisfying sexual activity and sexual desire, and greater decreases in distress, than placebo-treated women. Accurate clinical assessment and individualized management of sexual symptoms are fundamentally important for all menopausal women with HSDD or other sexual problems.     

Monolateral hypoplasia of the motor vagal nuclei in a case of sudden infant death syndrome

During the development of motor vagal nuclei (MVN), the neuroblasts of the myeloencephalic basal plate migrate in the dorsolateral direction to form the dorsal motor vagal nucleus (DMVN) and ventrolaterally to form the ventral motor vagal nucleus (VMVN). Those neuroblasts that remain close to the median sulcus will form the hypoglossal nucleus. In support of the congenital origin of the alteration of the MVN in sudden infant death syndrome (SIDS), we report the case of an 8‐month‐old female child who was found dead in her cot. The neuropathological assessment revealed that the medullary triangle of the 4th ventricle floor was asymmetric, owing to the presence of three prominences to the left side of the median sulcus. The medial prominence corresponded to the hypoglossal nucleus, which showed a marked increase in the number of large neurons; the intermediate prominence corresponded to the DMVN whose large neurons were reduced and were recognizable mainly at the level of the medial fringe; the lateral prominence corresponded to the solitary nucleus. The left solitary tract showed a reduction of the transverse diameter. Also, the left VMVN showed marked reduction in the number of neurons. Inflammatory and astrocytic reactions were absent. We suggest that in SIDS cases the hypocellularity of the MVN and the increased number of neurons of the hypoglossal nucleus are intimately related, indicating a congenital alteration due to incomplete migration of the vagal neuroblasts with abnormality of the autonomic cardio‐respiratory control.     

Benign neonatal sleep myoclonus: case report and follow-up of four members of an affected family.

Benign neonatal sleep myoclonus (BNSM), characterized by myoclonic jerks of the extremities only in non-REM sleep, occurs in the first months of life with spontaneous disappearance within 3-4 months. We examined five siblings with typical BNSM, at the 3-10 years follow-up neurological examination. Psychomotor development, cognitive functions and EEG were completely normal. These cases confirm that BNSM is a self limited and nonepileptic disorder.     

Special problems in the surgical treatment of megaesophageal cardial achalasia. A clinical case]

The paper report the case of a patient brought to the Authors' attention suffering from megaesophageal cardial achalasia who had already undergone gastroduodenal resection according to BII. It was considered worthwhile to report this case due to the problems which arose concerning the choice of a thoracic rather than abdominal route owing to the impossibility of associating cardiomyotomy with anti-reflux plastica surgery because of the reduced dimensions of the stomach.     

The use of bipolar PlasmaKinetic resectoscope in endoscopic resection of the prostate: our experience

Prostatic endoscopic resection (TURP) is a reference method in the treatment of prostatic obstruction. In the past decades, the method used a monopolar resectoscope. In the last years, various technologies have been studied to improve the efficacy of endoscopic resection. As per our experience, we have thence ascertained the variations of the hematic crasis and of the mictional asset in TURP patients treated with bipolar knives. 20 patients underwent bipolar plasmakinetic resection of the prostate. Their age ranged between 58 yrs and 82 yrs (av.: 70.2 yrs), the adenoma volume, checked with TR ultrasound scanning, was between 33 and 44 cc (av.: 37.6), the Qmax was between 6.4 and 9.0 mL/min (av.: 7.42 mL/min). A 24Ch resectoscope and spinal anesthesia were used. Bleeding during resection was never relevant; therefore resection never had to be stopped. After about 36 hours from surgery, the patients' sanguification was checked again: a 6.53% reduction of the number of erythrocytes, compared to pre-surgery data, was observed, together with a 6.73% decrease of hemoglobin concentration, and a 6.3% decrease of hematocrit. Continuous irrigation was suspended during the first day, catheter was removed on the 48th hour in 15 cases, and on the 72nd in 5 cases: the patients were discharged on day 3 in 16 cases, and on day 4 in 4 cases. A flux evaluation was performed after 3 months, which showed a Qmax between 16.6 and 24 mL/min (av.: 19.11), with a significant increase in the maximum flow rate. The use of the new technologies in prostatic endoscopic resection has allowed us to improve the efficacy of such a method. Above all, the use of a bipolar electrosurgical knife enables us to associate a basal hemostasis with the resection of the prostatic tissue. Thus, the hematic loss is low, as we have been able to ascertain also in our own experience. This gave us the possibility to quickly stop continuous irrigation and to early remove the catheter. This way, hospitalization was sensibly reduced (av. 76.8 hours). The maximum flow rate, in the short term, has been good. We have been able, in our experience, to assess that this technology represents a useful guarantee to improve the results of prostatic endoscopic resection.     

Current clinico-therapeutic trends in essential varicocele

Serum Interferon (IFN)-Neutralizing Antibodies and Bioactivities of IFNs in Patients with Severe Type II Essential Mixed Cryoglobulinemia

The efficacy of alpha interferon (IFN-α) in the treatment of severe type II essential mixed cryoglobulinemia (EMC) has been reported previously. In some patients, the development of neutralizing antibodies to recombinant IFN-α (rIFN-α) can affect the clinical response achieved with rIFN-α; a second treatment with natural IFN-α preparations may reinduce the clinical response. In the present study the ability of leukocyte IFN (LeIFN) to restore the response was investigated from a pharmacodynamic viewpoint. Specifically, the pharmacodynamic profiles of different IFN-α preparations were studied by measuring the serum neopterin levels and the levels of expression of protein MxA mRNA in in vivo peripheral blood mononuclear cells in two patients with EMC whose resistance to rIFN-α2a treatment increased concomitantly with the development of neutralizing antibodies. These markers were measured before injection and at 24 and 48 h after a single injection of rIFN-α2a, consensus IFN [(C)IFN], or LeIFN. No increase or only a slight increase in MxA mRNA levels was detectable after administration of rIFN-α2a or (C)IFN, whereas a significant increase (≥10-fold) in MxA mRNA expression was recorded following administration of LeIFN. The neutralizing antibodies to rIFN-α2a cross-react with (C)IFN. Sera from these patients neutralized most but not all of the subtypes present in the natural IFN-α (LeIFN) mixture, and no significant increase in neopterin levels was observed after these patients were switched to LeIFN treatment. In summary, the data demonstrate that the problem of neutralizing antibodies still exists and that LeIFN may induce an increase in the level of MxA mRNA expression but not an increase in neopterin levels in patients who are resistant to treatment with rIFN-α2a or (C)IFN.
