Correlation Between Long-Term Acetylsalicylic Acid Use and Prostate Cancer Screening with PSA. Should We Reduce the PSA Cut-off for Patients in Chronic Therapy? A Multicenter Study.

Purpose: To evaluate the prostate cancer (PCa) detection rate in men with chronic use of Aspirin and to compare it with the detection rate of non-users. Patients and Methods: Prospectively maintained database regarding patients undergoing prostate biopsy over the last 10 years in five institutions. Patients were divided into two groups according to their exposure to Aspirin. We relied on multivariable linear and logistic regression models to test whether Aspirin administration was associated with lower PSA values at prostate biopsy, higher PCa diagnosis, and higher Gleason Grade Grouping (GGG) at biopsy. Results: Were identified 1059 patients, of whom 803 (76%) did not take Aspirin vs 256 (24%) were taking it. In multivariable log-linear regression analysis, Aspirin administration was associated with lower PSA levels (OR 0.83, 95% CI 0.71-0.97, p = 0.01), after controlling for age, prostate volume, smoking history, associated inflammation at prostate biopsy, presence of PCa at biopsy, and GGG. In multivariable logistic regression analysis, Aspirin administration was not found to be a predictor of PCa at prostate biopsy (OR 1.40, 95% CI 0.82-2.40, p = 0.21) after controlling for age, PSA, smoking history, prostate volume, findings at digital rectal examination and the number of biopsy cores. In patients with PCa at prostate biopsy (n = 516), Aspirin administration was found to predict higher GGG (OR 2.24, 95% CI 1.01-4.87, p = 0.04). Conclusion: Aspirin administration was found to be a predictor of more aggressive GGG. These findings suggest that a lower PSA threshold should be considered in patients taking Aspirin, as, despite low PSA levels, they might harbour aggressive PCa.

Can We Clinically Distinguish Anejaculation From Retrograde Ejaculation in Patients on α1A-Blockers Therapy for Lower Urinary Tract Symptoms?

OBJECTIVE: To investigate the physiopathology of ejaculatory disorders (EjD) and discriminate between retrograde ejaculation (REj) and anejaculation (AEj) induced by α1A-blockers, through the association between the mean postorgasm seminal vesicle volume and the presence of sperm in midstream urine, in patients with moderate-to-severe lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement. MATERIALS AND METHODS: Therapy-naïve male patients with LUTS and without previous EjD were treated with α1A-blockers. Pre- and post-treatment EjD were investigated through question 4 of the 4-item Male Sexual Function questionnaire and the Male Sexual Health Questionnaire for Ejaculatory Dysfunction Short Form (MSHQ-EjD-SF). After 12 weeks, postorgasm urine was collected for sperm count and seminal vesicle volume was calculated through transrectal ultrasound. RESULTS: All 42 patients reported with EjD after treatment with α1A-blockers: 4-item Male Sexual Function questionnaire and MSHQ-EjD-SF Q4 scores were significantly higher (P <.001) and MSHQ-EjD-SF Q1-3 score was significantly lower (P <.001) than before. Postorgasm seminal vesicle volume was significantly higher in patients with postorgasm sperm-negative urine (AEj), and lower in patients with postorgasm sperm-positive urine (REj; P <.001). CONCLUSION: We clearly demonstrated an association between the presence of sperm in the midstream urine and seminal vesicle volume after orgasm, strongly confirming and differentiating the hypothesis of a dual etiology for EjD (REj vs AEj) secondary to α1A-blockers therapy for LUTS.

Mediastinal syndrome from plasmablastic lymphoma in human immunodeficiency virus and human herpes virus 8 negative patient with polycythemia vera: a case report.

BACKGROUND: Plasmoblastic lymphoma is a rare and aggressive subtype of diffuse large B cell lymphoma, which occurs usually in the jaw of immunocompromised subjects. CASE PRESENTATION: We describe the occurrence of plasmoblastic lymphoma in the mediastinum and chest wall skin of an human immunodeficiency virus-negative 63-year-old Caucasian man who had had polycytemia vera 7 years before. At admission, the patient showed a superior vena cava syndrome, with persistent dyspnoea, cough, and distension of the jugular veins. Imaging findings showed a 9.7 × 8 × 5.7 cm mediastinal mass. A chest wall neoformation biopsy and ultrasound-guided fine-needle aspiration biopsy of the mediastinal mass allowed diagnosis of plasmoblastic lymphoma and establishment of an immediate chemotherapeutic regimen, with rapid remission of compression symptoms. CONCLUSIONS: Plasmoblastic lymphoma is a very uncommon, difficult to diagnose, and aggressive disease. The presented case represents the first rare mediastinal plasmoblastic lymphoma in a human immunodeficiency virus-/human herpesvirus-8-negative patient. Pathologists should be aware that this tumor does appear in sites other than the oral cavity. Fine-needle aspiration biopsy is a low-cost, repeatable, easy-to-perform technique, with a high diagnostic accuracy and with very low complication and mortality rates. Fine-needle aspiration biopsy could represent the right alternative to surgery in those patients affected by plasmoblastic lymphoma, being rapid and minimally invasive. It allowed establishment of prompt medical treatment with subsequent considerable reduction of the neoplastic tissue and resolution of the mediastinal syndrome.

Thoracoscopy in pleural effusion--two techniques: awake single-access video-assisted thoracic surgery versus 2-ports video-assisted thoracic surgery under general anesthesia.

UNLABELLED: Awake single access video-assisted thoracic surgery with local anesthesia improves procedure tolerance, reduces postoperative stay and costs. MATERIALS & METHODS: Local anesthesia was made with lidocaine and ropivacaine. We realize one 20 mm incision for the 'single-access', and two incisions for the '2-trocars technique'. RESULTS: Mortality rate was 0% in both groups. Postoperative stay: 3 dd ± 4 versus 4 dd ± 5, mean operative time: 39 min versus 37 min (p < 0.05). Chest tube duration: 2dd ± 5 versus 3 dd ± 6. COMPLICATIONS: 11/95 versus 10/79. CONCLUSION: Awake technique reduce postoperative hospital stay and chest drainage duration, similar complications and recurrence rate. The authors can say that 'awake single-access VATS' is an optimal diagnostic and therapeutic tool for the management of pleural effusions, but above extends surgical indication to high-risk patients.

Nodular histiocytic/mesothelial hyperplasia as consequence of chronic mesothelium irritation by subphrenic abscess.

PURPOSE: Pleural nodular histiocytic/mesothelial hyperplasia is a nodular histiocytic/mesothelial proliferation, often delimiting cystic cavities, due to irritation by a pulmonary noxa. Case report results: The patient had right pleural parietal and diaphragmatic thickness, with pleural effusion, without lung alterations. He previously underwent left hemicolectomy and liver resection, due to a diverticulitis and a liver histiocytes-rich abscess. Video-assisted thoracoscopy biopsy showed a double population of reactive mesothelial cells and histiocytes. CONCLUSION: Nodular histiocytic/mesothelial hyperplasia represents a potential pitfall for pathologists. Immunohistochemistry is crucial for the differential diagnosis with some malignancies. We suggest that in our patient, a chronic mesothelium inflammation happened by transdiaphragmatic involvement as a consequence of the liver abscess. Some pathogenetic mechanisms are hypothesized.

Current role of computed tomography-guided transthoracic needle biopsy of metastatic lung lesions.

AIM: As part of the Catania symposium on lung metastasectomy we reviewed our practice of computed tomography (CT)-guided percutaneous transthoracic needle biopsy of pulmonary metastatic lesions with particular emphasis on diagnostic accuracy and nature of complications lesions. MATERIALS & METHODS: 25 patients with metastatic lesions of the lung have been evaluated between May 2010 and February 2014. Inclusion criteria consisted of patients with histologically confirmed, metastatic disease of the lung, those receiving a CT-guided needle biopsy, were at least 18 years of age; and with adequate hepatic, renal and hematological function. We recorded also the size of the sampled lesions, their distance from the pleura, the complications encountered (pneumothorax and thoracostomy tube placement), the cytological diagnosis and the outcome in all the cases. RESULTS: CT-guided percutaneous transthoracic needle biopsy were performed on 23 of 25 patients with suspected lung metastases. 17 males and six females with a mean age of 71.4 years. The mean size of lesions was 4.2 cm (range: 1 to 17 cm). For CT-guided needle biopsy, an 18 gauge semi-automatic needle biopsy device was used. Of 23 biopsies, 20 (87%) yielded a correct diagnosis with specific histological typing for metastasis. Pneumothorax was the most common complication occurring in four cases (5.7%). CONCLUSION: CT-guided percutaneous transthoracic needle biopsy is a firm, useful and safe technique for the diagnosis of suspected pulmonary metastases as it avoids open biopsy in most cases.
