Pregnant woman presenting with a gross retroperitoneal mass: surgical treatment with caval replacement.

A 40-year-old woman in the twenty-fifth week of pregnancy presented with a gross retroperitoneal mass. At the end of the pregnancy, the patient was submitted to surgery, and the gross infiltration of the inferior vena cava wall required the resection of the vena cava with its prosthetic substitution. The histopathological examination demonstrated the presence of a leiomyosarcoma of the inferior vena cava.

Evaluation of rectal sensory and motor function by means of the electronic barostat after stapled hemorrhoidopexy.

Purpose: Stapled hemorrhoidopexy is designed to replace the hemorrhoids into the anal canal by excising the redundant rectal mucosa above the anorectal ring, thus resulting in an intrarectal suture. Few studies have evaluated rectal function after this procedure. This prospective study was designed to use the electronic barostat to assess whether rectal motor and sensory functions change after stapled hemorrhoidopexy.

Radical nephrocapsulectomy and caval thrombectomy with extracorporeal circulation and deep hypothermic circulatory arrest in right anterior minithoracotomy: a minimally invasive approach.

Objectives: Radical nephrocapsulectomy and cavoatrial thrombectomy with median sternotomy and abdominal access, using extracorporeal circulation (ECC) and deep hypothermic circulatory arrest (DHCA), has become the gold standard treatment for renal cell carcinoma (RCC) with neoplastic thrombosis of the suprahepatic and intrapericardial inferior vena cava (IVC) and right atrium (RA). Any modification of surgical techniques should be compared with this therapeutic strategy.

Methods: In our quest to identify a minimally invasive approach and to apply available technology to ensure patient safety, even in cases of RCC with suprahepatic IVC and RA thrombosis, we identified a therapeutic approach that foresees en bloc radical nephrocapsulectomy, with ECC and DHCA in right anterior minithoracotomy.

Prognostic value of lymph node dissection in patients with muscle-invasive transitional cell carcinoma of the upper urinary tract.

Objectives: To analyze the prognostic role of lymphadenectomy (LND) in patients with muscle-invasive transitional cell carcinoma (TCC) of the upper urinary tract (UUT) managed with radical surgery.

Methods: From 1986 to 2003, 132 consecutive patients with muscle-invasive TCC of the UUT underwent radical surgery. LND was performed in 95 cases.

Effect of autologous blood transfusion on the rate of biochemical recurrence after radical prostatectomy.

Objective: To test the association between autologous blood transfusion (ABT) and biochemical recurrence (BCR) after radical prostatectomy (RP) in a large group of contemporary patients.

Patients And Methods: We analysed 1291 patients treated with RP; Kaplan-Meier analysis was used to graphically explore the association between ABT and BCR. Cox regression models addressed the association between ABT and BCR in univariate and multivariate analyses, after adjusting for preoperative prostate specific antigen level, pathological Gleason sum, extracapsular extension, seminal vesicle invasion and lymph node invasion.

Differences in the rate of lymph node invasion in men with clinically localized prostate cancer might be related to the continent of origin.

Objective: To test whether the rate of lymph node invasion (LNI) differs between patients treated with radical prostatectomy (RP) at a European or a North American centre.

Patients And Methods: In all, 1385 men had RP with bilateral lymphadenectomy for clinically localized prostate cancer (587 from Dallas, Texas and 798 from Milan, Italy). Univariate and multivariate analyses focused on the association between the continent of origin and the rate of LNI, after controlling for prostate-specific antigen (PSA) level, clinical stage, biopsy Gleason sum and the number of examined and removed lymph nodes.

Role of serotonergic gene polymorphisms on response to transcranial magnetic stimulation in depression.

Transcranial magnetic stimulation (TMS) has been extensively studied as a treatment for Major Depression. However, no data are available about the role of genetic variables on the response to this treatment. We analysed the role of two polymorphisms that influence the response to antidepressants: the polymorphisms of the serotonin transporter promoter region (SERTPR) and of the 5-HT(1A) serotonergic receptor promoter region (-1019C/G).

Systematic assessment of the ability of the number and percentage of positive biopsy cores to predict pathologic stage and biochemical recurrence after radical prostatectomy.

Objectives: We hypothesized that the number and/or percentage of positive cores, proxies of tumor volume, could improve the ability to predict pathologic stages and/or biochemical recurrence (BCR). To test this hypothesis, we examined radical retropubic prostatectomy (RRP) data from three centers on two continents.

Material And Methods: Clinical data from men undergoing RRP at three different institutions were used to predict pathologic stages and BCR.

Response to SSRIs and role of the hormonal therapy in post-menopausal depression.

The aim of this study is to prospectively evaluate the antidepressant response to SSRIs in depressed post-menopausal women with or without hormonal therapy (HT), and to analyze the possible influence of basal serum levels of gonadotropins and sexual hormones on the antidepressant response. 170 post-menopausal women with a depressive episode (DSM-IV criteria)--47 on HT and 123 not on HT--started the treatment with an SSRI. Depressive symptoms were assessed at baseline and 7 weeks thereafter by raters blind to treatment regimen.

Massive apoptosis erodes nasal mucosa of cocaine abusers.

Background: A threatening occurrence in some cocaine abusers is the progressive destruction of nasal structures (cocaine-induced midline destructive lesions [CIMDL]) that may end in a highly severe disease.

Methods: Thirty patients with CIMDL, 10 healthy patients, 10 patients affected by nasal polyposis, and 10 patients affected by Wegener granulomatosis were observed. Biopsy specimens of nasal mucosa were analyzed by immunohistochemistry for caspases-3, -9 and -8 and by the terminal deoxynucleotidyl transferase-mediated dUTP-digoxygenin nick end labeling (TUNEL) method.

A double-blind, randomised, controlled clinical trial of acetyl-L-carnitine vs. amisulpride in the treatment of dysthymia.

Aim: Evaluation of the effect of acetyl-L-carnitine (ALCAR) vs. amisulpride measured by total Hamilton Depression Rating Scale score (HAM-D(21)) in patients with pure dysthymia (DSM IV). Two hundred and four patients were randomised and treated with ALCAR 500 mg b.

Tissue factor and CCL2/monocyte chemoattractant protein-1 released by human islets affect islet engraftment in type 1 diabetic recipients.

Islet survival in the early posttransplantation period is likely to be influenced by inflammatory events in and around islets. Twenty-seven human islet preparations were transplanted by 24 infusions into 14 patients with brittle type 1 diabetes under the Edmonton protocol. Patients were monitored for their coagulation [cross-linked fibrin degradation products (XDPs)] and liver function test [aspartate and alanine aminotransferase (AST and ALT)] as markers of early posttransplant complications, and these were correlated with in vitro islet number, purification, volume, monocyte-chemoattractant protein-1 (CCL2/MCP-1) and tissue factor (TF) islet release.

The C(-1019)G polymorphism of the 5-HT1A gene promoter and antidepressant response in mood disorders: preliminary findings.

Several studies have demonstrated the involvement of 5-HT1A receptors in the pathogenesis of depression and in the antidepressant response to SSRIs. A functional new variant in the promoter region of the 5-HT1A gene was recently reported (-1019 C>G). The aim of this study is to investigate a possible association between this 5-HT1A receptor variant and antidepressant response to fluvoxamine in a sample of 262 mood-disorder subjects (151 major depressed and 111 bipolars) treated with fluvoxamine for 6 wk.

Genetic features of antidepressant induced mania and hypo-mania in bipolar disorder.

Rationale And Objectives: The present study investigated possible genetic association between some polymorphisms possibly involved in antidepressant response and the occurrence of manic or hypo-manic switches during antidepressant treatment.

Methods: We retrospectively examined 169 individuals with a diagnosis of bipolar disorder (BP) type I ( n=103) and II ( n=66), who presented at least one sudden manic or hypo-manic episode (according to DSM IV criteria) during antidepressant therapy, that occurred within a period of 3 weeks from the beginning of the treatment and without any interposed period of well being ("manic switch"). They were compared with a sex, age, and ethnicity-matched group of 247 subjects, randomly selected from our pool of bipolar subjects, who never showed switches.

Clinical features of antidepressant associated manic and hypomanic switches in bipolar disorder.

The present study investigated possible clinical differences between bipolar patients with and without manic or hypomanic switch during antidepressant (AD) treatment. The authors undertook a retrospective assessment of 169 individuals affected by bipolar disorder type I (BP I: n=96) and II (BP II: n=73) who experienced at least one manic or hypomanic episode following depression without any interposed normothymic period ("manic switch") during AD therapy. They were compared with a sex, age (+/-5 years), and ethnicity-matched group of 247 subjects, randomly selected from our pool of bipolar subjects who have never had manic switches.
