Endometriosis: seeking optimal management in women approaching menopause.

The incidence of endometriosis in middle-aged women is not minimal compared to that in the reproductive age group. The treatment of affected women after childbearing age to the natural transition toward menopause has received considerably poor attention. Disease management is problematic for these women due to increased contraindications regarding hormonal treatment and the possibility for malignant transformation, considering the increased cancer risk in patients with a long-standing history of the disease. This state-of-the-art review aims for the first time to assess the benefits of the available therapies to help guide treatment decisions for the care of endometriosis in women approaching menopause. Progestins are proven effective in reducing pain and should be preferred in these women. According to the international guidelines that lack precise recommendations, hysterectomy with bilateral salpingo-oophorectomy should be the definitive therapy in women who have completed their reproductive arc, if medical therapy has failed. Strict surveillance or surgery with removal of affected gonads should be considered in cases of long-standing or recurrent endometriomas, especially in the presence of modifications of ultrasonographic cyst patterns. Although rare, malignant transformation of various tissues in endometriosis patients has been described, and management is herein discussed.

Pelvic myeloid sarcoma: a multidisciplinary approach.

Myeloid sarcoma (MS) is a rare tumor mass derived from the extramedullary proliferation of blasts of one or more of myeloid lineages. It usually occurs at an anatomical site other than the bone marrow (BM). Among the anatomical site which may be involved, female genital tract is a rare localization. When MS follows a previous history of myeloid pathology it is usually associated to a poor prognosis. To date this disease was managed with exploratory laparotomy or with surgical debulking. The authors report a case of laparosc6pic diagnosis of a pelvic myeloid sarcoma in a patient previously affected by acute mycloid leukemia, evidencing the importance of minimally invasive diagnosis and subsequent multidisciplinary management.

Predictors of nonfatal reinfarction in survivors of myocardial infarction after thrombolysis. Results of the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico (GISSI-2) Data Base.

OBJECTIVES: This study was designed to reassess the prediction of recurrent nonfatal myocardial infarction in patients recovering from acute myocardial infarction after thrombolysis. BACKGROUND: Recurrent nonfatal myocardial infarction is a strong and independent predictor of subsequent mortality. Current knowledge of risk factors for nonfatal reinfarction is still largely based on data gathered before the advent of thrombolysis. Thus, this prospective study was planned to identify harbinger of nonfatal reinfarction in the postinfarction patients of the multicenter Grouppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico (GISSI-2) trial. METHODS: Predictors of nonfatal reinfarction at 6 months were analyzed by multivariate technique (Cox model) in 8,907 GISSI-2 survivors of myocardial infarction with clinical follow-up, relying on a set of prespecified variables reflecting residual ischemia, left ventricular failure or dysfunction, complex ventricular arrhythmias, comorbidity as well as demographic and historical factors. RESULTS: The postdischarge to 6-month incidence rate of nonfatal reinfarction was 2.5%. Independent predictors of nonfatal reinfarction were cardiac ineligibility for exercise test (relative risk 2.97, 95% confidence interval [CI] 1.98 to 4.45), previous myocardial infarction (relative risk 1.70, 95% CI 1.22 to 2.36) and angina at follow-up (relative risk 1.50, 95% CI 1.10 to 2.04). On further multivariate analysis, performed in 6,580 patients with both echocardiographic and electrocardiographic monitoring data available, a history of angina emerged as an additional risk predictor (relative risk 1.58, 95% CI 1.10 to 2.25). CONCLUSIONS: The 6-month incidence of nonfatal reinfarction is rather low in survivors of myocardial infarction after thrombolysis. Cardiac ineligibility for exercise testing and a history of coronary artery disease are risk predictors. Recurrent nonfatal infarction is not predictable by qualitative variables reflecting residual ischemia, except by postdischarge angina. Prediction of nonfatal reinfarction appears less accurate than prediction of mortality, as almost 50% of reinfarctions occur in patients without any of the identified risk factors.

Electrocardiographic evolutionary changes and left ventricular remodeling after acute myocardial infarction: results of the GISSI-3 Echo substudy.

OBJECTIVES: The aim of this study was to describe the electrocardiographic (ECG) evolutionary changes after an acute myocardial infarction (AMI) and to evaluate their correlation with left ventricular function and remodeling. BACKGROUND: The QRS complex changes after AMI have been correlated with infarct size and left ventricular function. By contrast, the significance of T wave changes is controversial. METHODS: We studied 536 patients enrolled in the GISSI-3-Echo substudy who underwent ECG and echocardiographic studies at 24 to 48 h (S1), at hospital discharge (S2), at six weeks (S3) and six months (S4) after AMI. RESULTS: The number of Qwaves (nQ) and QRS quantitative score (QRSs) did not change over time. From S2 to S4, the number of negative T waves (nT NEG) decreased (p < 0.0001), wall motion abnormalities (%WMA) improved (p < 0.001), ventricular volumes increased (p < 0.0001) while ejection fraction remained stable. According to the T wave changes after hospital discharge, patients were divided into four groups: stable positive T waves (group 1, n = 35), patients who showed a decrease > or =1 in nT NEG (group 2, n = 361), patients with no change in nT NEG (group 3, n = 64) and those with an increase > or =1 in nT NEG (group 4, n = 76). The QRSs and nQ remained stable in all groups. Groups 3 and 4 showed less recovery in %WMA, more pronounced ventricular enlargement and progressive decline in ejection fraction than groups 1 and 2 (interaction time x groups p < 0.0001). CONCLUSIONS: The analysis of serial ECG can predict postinfarct left ventricular remodeling. Normalization of negative T waves during the follow-up appears more strictly related to recovery of regional dysfunction than QRS changes. Lack of resolution and late appearance of new negative T predict unfavorable remodeling with progressive deterioration of ventricular function.

A randomised clinical trial comparing idarubicin and cytarabine to daunorubicin and cytarabine in the treatment of acute non-lymphoid leukaemia. A multicentric study from the Italian Co-operative Group GIMEMA.

255 patients with acute non-lymphoid leukaemia (ANLL), observed between October 1984 and June 1987, entered a chemotherapy regimen consisting of induction therapy with cytarabine in combination with idarubicin (IDA/ARA) or daunorubicin (DNR/ARA), followed by consolidation with four courses of IDA + ARA plus 6-thioguanine (6-TG) or DNR + ARA + 6-TG and a 6 month maintenance therapy with 6-TG and ARA. The median age was 62 years (range 55-78 years) and 33 were aged more than 70 years. The treatment groups were comparable for median age, FAB type, performance status and initial blood counts. 249 patients were randomised, 124 to the IDA/ARA arm and 125 to the DNR/ARA arm. Complete remission was achieved in 50 patients (40%) on the IDA/ARA treatment program and 49 patients (39%) on DNR/ARA. No definite differences were found between patients receiving IDA/ARA and those treated with DNR/ARA as far as complete response (CR), overall survival, failure free and relapse free survival are concerned. 74% of the complete responders in the IDA/ARA arm and 51% in the DNR/ARA arm achieved CR after a single course of treatment. Resistant leukaemia was observed in 13.7% of the patients in the IDA/ARA arm and in 31.2% in the DNR/ARA one, whereas hypoplastic death occurred in 29% and 14.4%, respectively. In conclusion, our data failed to show any advantage of idarubicin over daunorubicin even though there is some evidence that IDA, despite the higher toxicity, is more rapid in eradicating leukaemia as proved by the higher CR rate obtained after one course of induction.

Systolic anterior motion of the mitral valve. An unusual echocardiographic feature of mitral valve endocarditis.

An unusual M-mode echocardiographic feature of mitral valve endocarditis is described: systolic anterior motion of the mitral valve, likely due to mitral valve vegetations, protruding during systole into the left ventricular outflow tract. The presence of mitral valve vegetation was confirmed at operation.

Very early administration of ACE-inhibitors in acute myocardial infarction.

Recent trials have shown that ACE-inhibitors are safe and can reduce mortality and the occurrence of severe left-ventricular dysfunction (LVD) (when started within the first day after acute myocardial infarction (MI) and continued for 4 to 6 weeks thereafter). GISSI-3, ISIS-4 and CCS-1 studies show that more than half of the lives are saved by ACE-inhibitor treatment within the first week of therapy. Although the benefit from ACE-inhibitor is larger in patients presenting with congestive heart failure (Killip class >1), the number of lives saved in patients at low risk, who represent the majority of the population, is relevant. This supports the approach of treating all hemodynamically stable MI patients. Treatment could be stopped after about 1 month in patients without evidences of LVD while those with LVD should be continued on ACE-inhibitors for a long period of time.

[Hydatid cyst of the kidney. Case report]. / Cisti idatidea del rene. Descrizione di un caso.

The authors present a case of echinococcosis of the kidney that is interesting because of the uncommon site of localization; they illustrate their diagnostic and therapeutic approach to surgical and pharmacological management of the infection. Epidemiologically, hydatid cysts localized in the kidney occur far less often in northern Italy compared with the central-southern areas and the islands. However, echinococcosis should be suspected whenever symptoms include lumbar pain or swelling. Echography will reveal characteristic capsule and daughter cysts, while radiographic studies will often show a rim of calcification on the outline of the kidney. This information should be considered in conjunction with serologic tests (IgG-specific titers). If results to these tests are negative, abdominal computed tomography scans with contrast medium may be useful in demonstrating more details to establish diagnosis. Conservative (pericystectomy) or radical (nephrectomy) surgery is usually effective in curing the patient. Pharmacological therapy with albendazole can be a useful support in association with surgery or as an alternative single therapy in patients with other medical problems or spontaneous fistula formation that preclude surgery.

Intravenous versus oral initial load of propafenone for conversion of recent-onset atrial fibrillation in the emergency room: a randomized trial.

BACKGROUND: Non-valvular paroxysmal atrial fibrillation is a common clinical condition associated with a high risk of thromboembolism and hemodynamic problems which increase with the duration of arrhythmia. Therefore, even if arrhythmia ceases spontaneously within 24 hours in about half of the patients, a higher early conversion rate is desirable. Propafenone either by intravenous or oral load has been shown effective in conversion to sinus rhythm. METHODS: We consecutively randomized all emergency patients with non-valvular atrial fibrillation lasting no more than 48 hours to either intravenous or oral initial load of propafenone. They all received further oral doses if still on atrial fibrillation after the initial load. Exclusion criteria were: mean ventricular rate < 65 b/min, age > 75 years, recent acute myocardial infarction, overt heart failure, conduction defects, ventricular preexcitation, thyroid dysfunction, renal or hepatic insufficiency, pregnancy, current treatment with propafenone or other antiarrhythmic drugs, and intolerance to propafenone. Primary and secondary end-points were the conversion to sinus rhythm within 12 and 48 hours of randomization respectively. RESULTS: Ninety-seven patients were randomized to intravenous (n = 49) or oral (n = 48) treatment. Overall, sinus rhythm restoration occurred in 83.3% of patients within 12 hours and in 98.9% at 24 hours. Recovery rate resulted significantly greater for intravenous treatment at 1 and 3 hours (p < 0.001 and p = 0.001, respectively). At 6, 12 and 24 hours no significant difference between the two groups was observed (p = 0.77, p = 0.81 and p = 0.99, respectively). No patient needed treatment suspension. CONCLUSIONS: In patients with recent-onset non-valvular atrial fibrillation treated with propafenone within 48 hours, conversion to sinus rhythm occurred in more than 80% within 12 hours. Even if intravenous initial load appears to be slightly more rapid, the oral way is easier to administer and cheaper. The choice may depend on the specific organization of the single emergency room.

A look at recent hyperventilation studies: outcomes and recommendations for early use in the head-injured patient.

During the past decade, mounting controversy surrounding the use of hyperventilation for the treatment of head injury has raised concerns about its safety and therapeutic benefits. A recent investigation of the medical literature was conducted to determine if outcomes for the head-injured patient continued to support the use of indiscriminate, and often unmonitored, hyperventilation in the pre-hospital and early hospital phases of care, and to determine if current investigators are recommending the use of hyperventilation for the initial treatment of all unconscious head-injured patients. Findings suggest that head-injured patients in the pre-hospital and early phases of care are at increased risk for suffering hyperventilation-induced secondary brain injury. Current researchers are now recommending a highly monitored, cautions and selective approach to care; this approach calls our current practice into question.

Hyperventilation and head injury: controversies and concerns.

The use of hyperventilation for the treatment of severe head injuries has been the standard of care for more than two decades in the prehospital, emergency department and critical care settings. Controversy has surrounded its use, even when advocates recommended use for all unconscious, head-injured patients. Autoregulation, cerebral acidosis control, reduction of elevated intracranial pressure and the "steal phenomenon" were thought to be beneficial effects of hyperventilation therapy. Current researchers and developments in technology, however, have provided controversial information which suggests that hyperventilation therapy can be harmful, warranting the need for careful monitoring and selective treatment. This information calls into question the use of unmonitored hyperventilation therapy in the prehospital and early hospital settings.

One-Step Laparoscopic Management of a Female Adnexal Tumor of Wolffian Origin.

We report a case of female adnexal tumor of Wolffian origin (FATWO), a rare neoplasm arising from the mesonephric ducts. A 48-year-old woman came first to our center for a recent discovery of a pelvic mass. Transvaginal ultrasonographic findings suggested a solid right para-ovarian mass suspected to be malignant. After thorough counseling, the patient underwent operative laparoscopy for excision of the para-ovarian mass with frozen section (FS) examination resulting in the diagnosis of a poorly differentiated adenocarcinoma. In this case, FS results allowed performing a comprehensive oncological staging, through a totally laparoscopic extrafascial hysterectomy, bilateral adnexectomy, total omentectomy, pelvic wall peritonectomy, and pelvic, parasacral and para-aortic lymphadenectomy. Final pathological and immunohistochemical results confirmed the diagnosis of FATWO. To our knowledge, this is the first case of FATWO managed entirely by a minimally invasive laparoscopic approach in a single surgical session.

Isospin dependence of incomplete fusion reactions at 25 MeV/nucleon.

40Ca+;{40,48}Ca,46Ti reactions at 25 MeV/nucleon have been studied using the 4pi CHIMERA detector. An isospin effect on the competition between fusionlike and binarylike reaction mechanisms has been observed. The probability of producing a heavy residue is lower in the case of N approximately Z colliding systems as compared to the case of reactions induced on the neutron rich 48Ca target. Predictions based on constrained molecular dynamics II calculations show that the competition between fusionlike and binary reactions in the selected centrality bins can constrain the parametrization of the symmetry energy and its density dependence in the nuclear equation of state.

Fast ternary and quaternary breakup of the 197Au + 197Au system in collisions at 15 MeV/nucleon.

A new reaction mechanism of violent reseparation of a heavy nucleus-nucleus system, 197Au + 197Au, into three or four massive fragments in collisions at 15 MeV/nucleon has been observed. After reseparation, the fragments are almost exactly aligned, thus showing a very short time scale of the reseparation process, of about 70-80 fm/c.

Giant dipole resonance in the hot and thermalized 132Ce nucleus: damping of collective modes at finite temperature.

The gamma decay of the giant dipole resonance (GDR) in the 132Ce compound nucleus with temperature up to approximately 4 MeV has been measured, using the reaction 64Ni + 68Zn at E(beam) = 300, 400, and 500 MeV. The gamma and charged particles measured in coincidence with recoils are consistent with a fully equilibrated compound nucleus emission. The GDR width, obtained with the statistical model analysis, is found to increase almost linearly with temperature. This increase is rather well reproduced within a model including thermal shape fluctuations and the lifetime of the compound nucleus.
