Sexual dysfunction after elective endovascular or hand-assisted laparoscopic abdominal aneurysm repair.

Objective: To evaluate the incidence of sexual dysfunction and retrograde ejaculation after elective endovascular aneurysm repair (EVAR) and hand-assisted laparoscopic surgery (HALS) for abdominal aortic aneurysm (AAA).

Methods: A total of 100 patients eligible for elective repair of infrarenal AAAs were randomised in two groups: EVAR and HALS. The quality of sexual function was evaluated using the International Index of Erectile Function (IIEF), a 15-item questionnaire.

HPLC analysis of HbA1c in dried blood spot samples (DBS): a reliable future for diabetes monitoring.

To simplify collection and transport of blood for HbA1c measuring, we have studied the use of a special paper that absorbs a defined volume of capillary blood and quickly dries it (dried blood-spot, DBS). The DBS can be sent to a central laboratory using regular postal service and without temperature control. This system differs greatly from other proposed DBS methods for HbA1c because it overcomes the haemoglobin alterations during the drying and storing processes, that otherwise make this analysis unreliable.

A new and safe device for minimally invasive saphenous vein harvesting: results after 100 cases.

Purpose: : The saphenous vein is the most commonly used bypass conduit for coronary surgery. Endoscopic harvesting techniques are associated with significant reduction of wound complications but are time-consuming and expensive. The authors developed a device to perform minimally invasive harvesting of the saphenous vein-rapidly, inexpensively, and safely.

Isolated local recurrence of renal neoplasm with caval involvement 16 years after radical nephrectomy.

Objective: To report a case of local recurrence 16 years after radical nephrectomy; to analyse literature data concerning, treatment and prognosis.

Methods/results: We report a case of local recurence associated with caval trombosis who was underwent an en-bloc resection of vena cava along with pericaval lesion and caval replacement with PTFE prosthesis. The Authors reviewed and analysed literature data.

"Method-specific" stability of serum C-peptide in a multicenter clinical study.

A Central laboratory that participates in multicenter clinical studies must consider and study the parameters that condition the in vitro stability of the analytes. We evaluated the effect of temperature on serum C-peptide storage during transport from clinical research centers to the Central laboratory. In particular, the stability for storage lengths from 0 to 24-48 hours at temperatures of between -20 degrees C and +37 degrees C were studied: the C-peptide assay was performed by means of a chemiluminescence and a RIA method.

Off-pump myocardial revascularization. The single-suture technique: how to avoid any complication.

Coronary artery bypass grafting without cardiopulmonary bypass (CPB) is now an accepted technique of complete myocardial revascularization. The technique was originally described by Kolesov [Kolesov 1967] and later abandoned when the CPB became the gold standard for cardiac operations on the arrested heart. In the late 1980s off-pump coronary grafting was reintroduced by Benetti and Buffolo with very encouraging results, especially for high-risk patients [Benetti 1985, Buffolo 1996].

The acid-labile subunit of human ternary insulin-like growth factor-binding protein complex in girls with central precocious puberty before and during gonadotropin-releasing hormone analog therapy.

The aim of the study was to evaluate serum acid-labile subunit (ALS) concentrations and their relationship with other parameters of the human ternary IGF-I-binding protein (IGFBP) complex in girls with central precocious puberty (CPP) before and after pharmacological arrest of puberty. We studied serum ALS, free IGF-I, total IGF-I, IGFBP-3 levels and IGFBP-3 protease activity in 13 girls, aged 1.6-7.

Optimised determination of clobazam in human plasma with extraction and high-performance liquid chromatography analysis.

The analysis of clobazam by high-performance liquid chromatography and UV detection is described herein. After adding an internal standard, 600 microl of plasma were extracted under basic conditions onto disposable cartridges packed with celite. The organic extract was then evaporated to dryness and the residue reconstituted in 200 microl of mobile phase.

[Clinical-therapeutic aspects and surgical treatment of aortic coarctation associated with hypoplasia of the aortic arch in less than 3-month-old patients].

The surgical treatment of the CoAo plus Hypoplastic Aortic Arch is debated. The point is whether to treat or not the associated tubular hypoplasia performing an extended Resection and "End to End" Anastomosis (ERETE) or a subclavian flap angioplasty (Waldhausen). According to some report in the literature we called an arch hypoplastic if its diameter in the first or second portion was less than the patient body weight plus 1.

[Primary malignant melanoma of the vagina].

We report two cases of primary malignant melanoma of the vagina explaining the essential clinical pathological and therapeutic features. They themselves, added those represented in literature, might constitute a further contribution to best definition of the unusual genital pathology, especially as regards prognostic and therapeutic aspects.

Intracardiac extension of a calcified ovarian hemangioma--a case report.

The authors report a case of a fifty-five-year-old woman with clinical and echocardiographic diagnosis of right atrial myxoma. At fluoroscopy and phlebography a mobile calcified peduncle was appreciable originating from the left ovarian vein. This passed through the inferior cava to the right atrium where it wound round itself and extended into the right ventricle during diastole.

[Vulvar papillary hidrocystadenoma. Description of a case].

Papillary hidradenoma of the vulva is a benign neoplasm arising from apocrine sweat glands of the skin. The treatment of choice is local excision. The prognosis for the patient is excellent.

'Water-test': a simple method to assess sperm-membrane integrity.

The functional integrity of the membrane of sperm from semen samples collected from 10 fertile men (Group A) and from 50 infertile men (Group B) was assessed by studying the swelling reaction of sperm when suspended in a medium of distilled water ('Water-test'). The results were correlated with routine semen-analysis and with the results of Eosin-Y staining. The mean values for the 'Water-test' were significantly different (P less than 0.

Multicenter trial of prophylaxis with clindamycin plus aztreonam or cefotaxime in gynecologic surgery.

A prospective, randomized, multicenter study was conducted on the efficacy and safety of two prophylactic antibiotic regimens in both abdominal and vaginal hysterectomy. Patients received three intravenous doses of clindamycin (900 mg) plus either aztreonam (1 g) or cefotaxime (1 g); the doses were given at the induction of anesthesia and 8 and 16 hours later. A total of 170 patients undergoing abdominal hysterectomy and 142 patients undergoing vaginal hysterectomy completed the trial and were evaluated.

[Malignant tumors of the vulva. Incidence and epidemiologic characteristics].

Over recent years cancer of the vulva has occupied an important position among gynecological neoplasia. It is possible that in the future, due to increased life expectation and the consequent aging of the population, there will be a considerable increase in this pathology. Today the survival rate after five years in patients affected by this invasive tumour is just over 50%, notwithstanding the mutilating and complex surgical treatment.

Echocardiographic detection of aortic valve ring abscesses.

Valve ring abscess complication of infective endocarditis increases the expected morbidity and mortality rates of patients, but is seldom recognized by available noninvasive techniques. In our study, two-dimensional echocardiography successfully detected valve ring abscesses in eight patients with infective endocarditis affecting aortic valve prosthesis. Echocardiography showed the perivalvular abscess as an echo-free space in all patients.

5-Fluorouracil cardiotoxicity.

The authors report a case of cardiotoxicity secondary to 5-FU, the 67th in literature in a 46-year-old woman subjected to adjuvant therapy with a CMF protocol after surgical treatment for carcinoma of the breast, and presenting onset of clinical symptoms 16 hours after administration of the first dose. Analysis of previous cases reported in literature revealed no evidence of age or sex as risk factors. Doubts exist as to whether or not pre-existing heart disease and thoraco-mediastinic radiotherapy increase the risk.

Growth hormone and prolactin response to growth hormone-releasing in anorexia nervosa.

Anorexia nervosa (AN) is associated with several endocrine disorders. In order to investigate the role of these alterations, growth hormone-releasing hormone (GHRH) was administered in a group of 9 AN patients and in 9 healthy normal-weight women as control. Growth hormone (GH) and prolactin (PRL) levels were evaluated in both groups after GHRH and saline solution administration.

[Conduction disorders in aortic periprosthetic abscesses].

Active infective endocarditis (AIE) involving native and especially prosthetic aortic valve is often complicated by conduction abnormalities. These conduction disturbances are considered to represent extension of infection from the valve to the annulus and surrounding myocardium. The authors report their experience of conduction disorders in 6/8 patients in whom the aortic prosthetic valve infection was complicated by periprosthetic abscess.

Effect of subacute cabergoline treatment on prolactin, thyroid stimulating hormone and growth hormone response to simultaneous administration of thyrotrophin-releasing hormone and growth hormone-releasing hormone in hyperprolactinaemic women.

It is known that dopaminergic neurotransmission is involved in the control of PRL, TSH and GH secretion. Cabergoline (CAB) is a new ergolinic derivative with a long-acting dopaminergic activity. We evaluated 11 women with pathological hyperprolactinaemia before and during sub-acute CAB treatment (0.
