RESUMEN

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. Patients completed the IIEF preoperatively and at 12 months. The incidence of retrograde ejaculation was also evaluated. RESULTS: One- and 12-month mortality rates were zero. Three patients in the EVAR group (6%) and two patients in the HALS group (4%) reported an erectile dysfunction (p = NS). The quality of sexual function at 1 year was similar in both groups: total score of 66 in the EVAR group versus 68 in the HALS group (p = 0.66). Retrograde ejaculation was detected in three cases in the HALS group versus no case in the EVAR group. CONCLUSIONS: The HALS technique could be a minimally invasive alternative for sexually active males unsuitable for EVAR repair.

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. CONCLUSIONS: Local recurrence after radical nephrectomy is rare as it is reported only in 2-4% of patients. This condition is even rarer beyond 10 years especially if associated with caval trombosis. A case of isolated local recurrence of renal cell carcinoma with caval involvement 16 years after radical nephrectomy is described herein. To the best of our knowledge, this is the first case reported in literature. This case highlights the opportunity of a periodic check-up of patients submitted to radical nephrectomy, even many years after surgery

RESUMEN

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. A 20 microl aliquot was injected into chromatograph. The HPLC system was equipped with an Ultrasphere C8 analytical column coupled with an UV detector set at 235 nm. The mobile phase was an acetate buffer 20 mM, pH 5.5, containing acetonitrile and triethylamine 70:30:0.01 (v/v); the flow-rate was 1.8 ml/min. Using this method, clobazam can be detected with a sensitivity limit of 6 ng/ml and the RSD% intra- and inter-assay were lower than 5%. For its ruggedness and reliability, the proposed method is particularly suitable for therapeutic drug monitoring in epilepsy.

RESUMEN

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. Between January 1988 and December 1992 in our Institution 38 patients less than 3 months underwent aortic coarctation repair. In 14 cases we were able to consider the aortic arch as hypoplastic. These patients were aged between 3 days and 45 days (median 15 days), the body weight was between 2.6 and 3.9 kgs (median 3.2 kgs). 6 patients had CoAo as isolated lesion, in 3 cases there was Ventricular Septal Defect (VSD) associated. In 5 patients major intracardiac anomalies were associated (1 DORV, 1 TGA, 2 SV, 1 SV+Arterio-Ventricular discordance). In 7 cases in order to treat the arch an ERETE was performed. The other 7 patients had a Waldhausen procedure. In 5 cases a Pulmonary Artery Banding (PAB) was associated, in 1 case a palliative arterial switch operation. The hospital death was 43% (3 patients) in the ERETE group, and 28% (2 patients) in the Waldhausen group. The echocardiography and or angiography performed during the follow-up period showed a nice growth of the arch in both groups. Although from our present data it's impossible to get definitive conclusions, the ERETE doesn't give better result in terms of hospital death and long term aortic arch growth.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

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. The authors suspected the presence of a vascular leiomyoma. The tumor and its peduncle were removed by pulling through the right atrium during extracorporeal circulation. The site of origin was confirmed at pelvic surgery.

RESUMEN

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 0.01) between Groups A and B (84.8 +/- 3.5 versus 70.9 +/- 13.3, respectively). No significant correlations were observed in either Group A or B, between values for the 'Water-test' and values for the sperm count, the percentage of sperm with normal morphology and the percentage of motile sperm. There was a good correlation in both Group A (r = 0.86, P less than 0.01) and Group B (r = 0.92, P less than 0.01) between values for the 'Water-test' and those for the Eosin-Y test. These results indicate that the 'Water-test' is a simple and reliable test for evaluating sperm membrane integrity.

RESUMEN

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. Following abdominal hysterectomy infections occurred at the operative site in 1.2% of patients given a regimen including aztreonam and in 4.7% of those given a regimen including cefotaxime; the difference between the two groups was not significant. Neither were significant differences observed in the incidence of fever, the incidence of bacteriuria, the need for postoperative antibiotics, or the duration of postoperative hospitalization, although results were slightly better for patients receiving clindamycin plus aztreonam. Following vaginal hysterectomy, slightly but not significantly better results for the same parameters were obtained in the group given clindamycin plus cefotaxime. Diarrhea was the only adverse reaction attributable to antibiotic treatment and occurred more frequently in patients given cefotaxime. It was concluded that the two regimens were similarly effective and safe in preventing infections following hysterectomy.

RESUMEN

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. Greater attention on behalf of both patient and doctor to a difficult and often neglected symptomatology, the identification of effective risk factors and a greater knowledge of the natural history of this disease may allow early diagnosis in the future and possibly help reduce the incidence of the disease.

RESUMEN

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. Prosthetic vegetations were seen in the only patient who had a biological prosthesis and excessive prosthetic rocking was observed in cases with severe aortic regurgitation. In two patients, the first echocardiographic examination showed an echo-free space without evident clinical signs of endocarditis or significant valve regurgitation. Severe aortic insufficiency and congestive heart failure followed the enlargement of the echo-free space. Valve replacement was required in all but one patient. The echocardiographic findings were confirmed at surgery. In one patient, the extension of the abscess to the interventricular septum was not detected by the echocardiography.

RESUMEN

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. With regard to the causes of the syndrome, the authors are inclined to attribute its onset to an auto-immune mechanism. 5-FU-induced cardiotoxicity, though rare, should be borne in mind and the use of the drug should be discontinued at the first signs of cardiotoxicity.

RESUMEN

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. In the AN group, luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyrotropin (TSH) and cortisol serum levels were evaluated during GHRH administration; somatomedin-C (Sm-C) basal levels were also determined. In both groups, GHRH induced a prompt GH increase, which was significantly higher in AN patients (55.3 +/- 2.9 ng/ml, mean +/- SE) than in normal subjects (9.8 +/- 2.6 ng/ml: p less than 0.01). A significant positive correlation between mean GH basal values and GH peak after GHRH was observed only in the control group (R = 0.82, p less than 0.01). No significant relationship between GH mean peak and body mass index (BMI) or Sm-C, estradiol (E2) and glucose serum levels was found in AN patients. However, a positive significant correlation with triiodothyronine (T3) basal values was observed in this group (R = 0.80, p less than 0.01). Both groups showed no variation in PRL serum levels after GHRH infusion. Our data suggest the presence of a central derangement in hypothalamic control of pituitary function in patients with AN, which is not necessarily due to weight loss alone.

RESUMEN

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. They underline the importance of conduction abnormalities as early markers of severe complication in patients with AIE. In fact, their detection is a useful tool in revealing severe complications since clinical, laboratory and other noninvasive examinations do not always allow early diagnosis of the extension of infection to the surrounding myocardium.

RESUMEN

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 (0.8-1.2 mg/p.o.; 8 weeks). Simultaneous administration of TRH (200 micrograms i.v.) and GHRH 1-44 (50 micrograms i.v.) were carried out before and after 4, 8 and 10 week intervals from the beginning of CAB treatment. Basal PRL levels (2453.5 +/- S.E. 444.5 mU/l) were significantly reduced during CAB administration (week 4: 164.5 +/- 66.5 mU/l; week 8: 168.0 +/- 66.5 mU/l; P less than 0.01) and no variations were observed 2 weeks after drug discontinuation (week 10: 210.0 +/- 98.0 mU/l). PRL percentage change after TRH was increased by CAB (P less than 0.05). No variation in basal and TRH-stimulated TSH levels was found during CAB administration. A slight increase in GH basal levels (3.0 +/- 0.6 mU/l) was found after weeks 4 (6.4 +/- 2.0 mU/l) and 10 (5.8 +/- 1.6 mU/l) (P less than 0.05). GH response to GHRH was significantly enhanced (ANOVA: P less than 0.01) during sub-acute CAB treatment. A positive correlation was found between GH secretory area and weeks of CAB therapy (P less than 0.01). Our data show that CAB is very effective in lowering PRL secretion in hyperprolactinaemia, and is able to modify PRL and GH responses after TRH and GHRH. The increasing trend in GH basal and GHRH-stimulated GH levels seems to indicate that CAB can override the central dopaminergic tone which is operative in hyperprolactinaemia.
