RESUMO

In March 2004, a new law was introduced in Italy to regulate assisted reproduction; at present it is impossible to use more than a maximum of three oocytes per IVF cycle, nor can embryos or prezygotes (2PN cells) be selected or cryopreserved. The prohibitions introduced by the new law have, on the one hand, reduced the expectations of success of current techniques and, on the other hand, stimulated clinicians and embryologists to work on new therapeutic strategies so as to offer the highest chances of success with the lowest risks. In-vitro maturation (IVM) of oocytes fits very well with these new requirements: ovarian stimulation is avoided and the handling of spare oocytes is facilitated. The IVM protocol is an intriguing alternative to conventional IVF techniques, since it removes the side-effects of drug stimulation, especially ovarian hyperstimulation syndrome, and it also reduces the costs of the entire procedure, both in terms of 'time consumption' and 'patient/society costs for drugs'. In the authors' IVF centre the IVM technique has been used for more than a year, with significant success in terms of maturation and fertilization rates, percentage of embryo transfers, number of pregnancies and, finally, healthy babies born.

RESUMO

OBJECTIVES: To assess the potential of expectant management for simple ovarian cysts diagnosed by transabdominal or transvaginal ultrasonography. To compare the results of needle aspiration with those achieved with simple observation. DESIGN: Randomised trial. SETTING: Hospital department of obstetrics and gynaecology. SUBJECTS: 278 women with simple cysts randomly allocated to simple observation (143) or ultrasound guided fine needle aspiration (135) between 1990 and 1994. MAIN OUTCOME MEASURES: Resolution of cyst or development of malignancy. RESULTS: After six months 269 were available for follow up. The rate of resolution was 46% (59/128) with aspiration and 44.6% (63/141) with observation. Only the diameter of the cyst (P < 0.0001) was a significant independent prognostic factor for resolution in a multivariate analysis. Age and treatment had no significant effect. One woman was subsequently found to have borderline malignant changes on histopathological examination. Her cyst was detected by transabdominal ultrasonography. CONCLUSIONS: Expectant management for up to six months does not cause risks for the patients and allows spontaneous resolution in over a third of cases, avoiding the costs and risks of unnecessary surgery. Aspiration does not provide better results than simple observation.

RESUMO

OBJECTIVE: Our purpose was to evaluate the effects of two surgical techniques, closed vaginal vault with two layers of continous 3-0 polyglactin suture versus open vaginal vault with a locking 3-0 polyglactin suture, after abdominal hysterectomy. STUDY DESIGN: A prospective, randomized trial was performed. During the hospital stay and 4 to 8 weeks after the operation patients were observed for evidence of morbidity. RESULTS: Of the 273 evaluable subjects, 141 had the vaginal vault left open whereas 132 were closed. Ten (7.1%) and eight patients (6.1%) had infections at the operative site (pelvis or abdominal wound) (p = 0.92). A urinary tract infection was diagnosed in three (2.1%) and in four subjects (3.0%) (p = 0.46). A pelvic hematoma developed in two patients of each group (p = 0.66). Vault granulations were recorded in 11% and 12% of subjects (p = 0.97). CONCLUSIONS: This study failed to show some benefit in favor of either of the two surgical policies. A careful surgical technique and antibiotic prophylaxis seem to remain the most important factors in the prevention of postoperative morbidity.

RESUMO

OBJECTIVES: To evaluate the role of needle aspiration in the management of endometriomas. DESIGN: Retrospective evaluation of the activity of the section of interventional ultrasound in a single tertiary care institution. SETTING: Department of Obstetrics and Gynecology, Ospedale S. Gerardo, Monza, University of Milan, Italy. PATIENTS: Two hundred nine premenopausal patients underwent aspiration for diagnostic purpose (n = 166), for relief of symptoms (n = 25), or with therapeutic intent (n = 18). RESULTS: Adequate material was obtained by all punctures. Early complications (self-limiting vagal symptoms or pain) occurred in eight cases. Short-term complications consisted of acute abdominal pain in three cases and infection in one. Three women required surgical treatment of the complication. At first examination after aspiration, persistence of the cyst was observed in all but four cases, including all cases who had undergone therapeutic aspiration. Nine patients reported relief of symptoms but six other patients referred onset or worsening of pelvic discomfort after aspiration. CONCLUSIONS: Ultrasound-guided aspiration of endometriomas is feasible. The transvaginal route reduces early complication but implies a risk of infection of 1.3%. However, drainage alone is ineffective as a therapeutic procedure and the applications of aspiration of endometriomas appear limited to some cases with diagnostic intent.

RESUMO

HCV-RNA was examined in serum and liver tissue obtained from 8 hepatitis B surface antigen (HBsAg) negative patients with liver nodules ranging in size from 2 to 11 cm. Histological examination of ultrasound-guided fine needle biopsies revealed the presence of hepatocellular carcinoma (HCC) in six patients (5 of whom were anti-HCV positive), cholangiocarcinoma in 1 patient (anti-HCV positive) and dysplastic regenerative nodule in 1 patient (anti-HCV negative). The HCCs were surrounded by cirrhosis (3 cases), chronic active hepatitis (CAH) (n = 2) and post hepatitic fibrosis (n = 1), the cholangiocarcinoma by CAH and the regenerative nodule by cirrhotic liver. Total and replicative intermediate HCV-RNA was analyzed by reverse-transcription-nested PCR of the 5'-untranslated region. The five patients with HCC had HCV-RNA in serum, in tumorous and surrounding liver tissues. The viral nucleic acid was also detected in the cirrhotic tissue surrounding the cholangiocarcinoma but not in the tumor. Two out of 5 HCC patients had replicative intermediate RNA (negative strand) in tumorous tissue, 4 in nontumorous tissue and 3 in serum. These results demonstrate that fine needle biopsy can provide sufficient material for both histological examination and HCV-RNA determination and suggest the existence of continuous viral replication during the carcinogenic process.

RESUMO

PURPOSE: To ascertain the complication rate associated with ultrasound (US)-guided puncture of gynecologic lesions. MATERIALS AND METHODS: Between 1986 and 1992, 878 transabdominal and 122 transvaginal US-guided punctures of gynecologic lesions were performed in 893 patients. Most of the procedures were performed in adnexal cysts (n = 838); the rest, in solid tumors (n = 66), mixed tumors (n = 56), or lymphoceles, abscesses, or fluid collections (n = 40). No anesthesia or antibiotic prophylaxis was routinely used. RESULTS: No life-threatening complication was recorded. Early complications (defined as complications that occurred within 24 hours after puncture) were recorded in 31 patients and consisted mainly of transient vagal symptoms or pain. Short-term complications (within 5 days after puncture) were recorded in 10 patients, six of whom required surgery. CONCLUSION: US-guided puncture of gynecologic lesions is safe in selected patients. Complication rates depend on the type of lesion and are very high in dermoid cysts, which should not be punctured, and extremely low in serous cysts, solid tumors, and mixed tumors.

RESUMO

Diagnosis of hepatocellular carcinoma smaller than 3 cm in diameter was possible in 64 (27.7%) of 231 consecutive cases. Ultrasonography provided the highest diagnostic sensitivity which was further increased by combining this methodology with laparoscopy. Evolution of nodules was more often multicentric but sometimes unicentric with slow growth. Surgical treatment in selected patients (small resections) was associated with high operative mortality (37.5%). Survival of patients (Child C excluded) after percutaneous ethanol injection under ultrasound guidance was 100% at three years.

RESUMO

The extension of the clinical use of Calcium entry Blockers (CEBs) indicates the need for a careful evaluation of possible adverse effects. Recently, contrasting data have been reported in some studies on the effect of CEBs on oral and i.v. glucose tolerance tests. The aim of the present study was to evaluate the potential diabetogenic properties of CEBs in normal subjects and their activities in diabetic patients. The data present in literature and also personal observations outline the safety of CEBs. In fact, there is a low possibility to derange the balance between insulin and glucagon secretion after acute and chronic administration of CEBs at conventional dosages.

RESUMO

A two-site solid phase immunoradiometric assay was developed for measurement of human alpha-fetoprotein, utilizing two high-affinity monoclonal antibodies directed against distinct and separate epitopes on the proteic structure. The analytical sensitivity of the assay is 0.5 ng/ml. The clinical sensitivity was evaluated by comparison of patients with cirrhosis and patients with hepatocellular carcinoma with cirrhosis. This assay gave good diagnostic discrimination. In a preliminary clinical trial, the specificity of the assay was 92.3%, the clinical sensitivity 88.2%, and predictive values were 78.9% in the clinically positive stage and 96.0% in the negative stage. The diagnostic efficacy of the assay was 91.3%.

RESUMO

A rare case of intrahepatic presinusoidal portal hypertension, due to massive infiltration of portal zones by chronic lymphatic leukaemia, revealed by sonographic patent umbilical vein, is reported. Sonographic patent umbilical vein which is considered specific for portal hypertension in liver cirrhosis may be present in myeloproliferative syndromes with liver involvement too.
