RESUMEN
Parental listening is believed to be an important quality of parent-child interactions, but its effects on adolescents are not well understood. The current study experimentally manipulated parental listening in video-recordings of an adolescent's self-disclosure to test effects on anticipated well-being (positive affect, self-esteem, and less negative affect) and self-disclosure intention. Good listening was manipulated in two situations relevant to vaping: hurt feelings of alienation from pressuring peers and having transgressed by vaping. Participants (N = 1001) aged 13-16 years viewed videos and reported on their anticipated reactions. Following a preregistered analytic plan, viewing good listening was found to predict greater well-being and self-disclosure intention. Consistent with self-determination theory, anticipated psychological need satisfaction for autonomy (freedom to be self-congruent) and relatedness (connectedness to parents) mediated the effects of listening on downstream outcomes. Parental listening effects on adolescent outcomes generalized across both situations of disclosure, in line with preregistered hypotheses.

OBJECTIVE: To present the template-guided transperineal prostate biopsy (TPB) outcomes for patients of two urologists from a single institution. PATIENTS AND METHODS: We conducted a prospective study of 409 consecutive men who underwent TPB between December 2006 and June 2008 in a tertiary referral centre using a standardized 14-region technique. The procedure was performed as day surgery under general anaesthesia with fluoroquinolone antibiotic cover. Follow-up took place within 2 weeks, during which time men were interviewed using a standardized template. Results were compared with those of the Australian national prostate biopsy audits performed by the Urological Society of Australia and New Zealand (USANZ). RESULTS: Indications for biopsy included elevated prostate-specific antigen (PSA) level (75%), with a median PSA level of 6.5 ng/mL, abnormal digital rectal examination (8%) and active surveillance (AS) re-staging (18%). The mean patient age was 63 years and two-thirds of patients were undergoing their first biopsy. A positive biopsy was found in 232 men, 74% of whom had a Gleason score of ≥7. The overall cancer detection rate was 56.7% (USANZ 2005 national audit = 56.5%). Stratified between those having their first TPB or a repeat procedure (after a previous negative biopsy), the detection rates were 64.4 and 35.6%, respectively. Significantly higher detection rates were found in prostates <50 mL in volume than in larger prostates (65.2 vs 38.3%, respectively, P < 0.001). Haematuria was the most common side effect (51.7%). Others included dysuria (16.4%), acute urinary retention (4.2%) and fever (3.2%). One patient (0.2%) had septicaemia requiring i.v. antibiotics. Repeat biopsy was not associated with increased complication rates. CONCLUSIONS: TPB is a safe and efficacious technique, with a cancer detection rate of 56.7% in the present series, and a low incidence of major side effects. Stratified by prostate volume, the detection rate of TPB was higher in smaller glands. Given the relatively low rate of serious complications, clinicians could consider increasing the number of TPB biopsy cores in larger prostates as a strategy to improve cancer detection within this group. Conversely, in patients on AS programmes, a staging TPB may be a superior approach for patients undergoing repeat biopsy so as to minimize their risk of serious infection.

PURPOSE: Anterior tumors are estimated to constitute 20% of prostate cancers. Current data indicate that transperineal biopsy is more reliable than transrectal biopsy in identifying these tumors. If correct, this superior reliability should result in an increased proportion of anterior tumors identified by transperineal biopsy. We investigated this hypothesis with reference to prostatectomy specimens. MATERIALS AND METHODS: Radical prostatectomy histopathology records were retrospectively examined. Patients were grouped based on primary transperineal or transrectal biopsy as the modality used to identify the initial cancer. After grouping, tumor location and size were recorded and, thus, the proportion of anterior tumors was determined. RESULTS: A total of 1,132 (414 transperineal and 718 transrectal) prostatectomy specimens were examined. Overall mean tumor size (1.8 and 2.0 cm(3)), stage (pT2 63.3% and 61%) and significance (5.1% and 5.1%) for the transperineal and transrectal methods were similar. However, the transperineal method was associated with proportionally more anterior tumors (16.2% vs 12%, p = 0.046), and identified them at a smaller size (1.4 vs 2.1 cm(3), p = 0.03) and lower stage (extracapsular extension 13% vs 28%, p = 0.03) compared to the transrectal method. The pT3 positive surgical margin rate for anterior vs other tumors was 69% vs 34.9%, respectively. CONCLUSIONS: Overall transrectal and transperineal biopsy identify cancers that are similar in size, stage and significance. However, transperineal biopsy detected proportionally more anterior tumors (16.2% vs 12%), and identified them at a smaller size (1.4 vs 2.1 cm(3)) and stage (extracapsular extension 13% vs 28%) compared to transrectal biopsy. Identifying anterior tumors early is important because the positive surgical margin rate for anterior pT3 lesions is significantly higher.

PURPOSE: We determined whether systematic template guided transperineal biopsies can accurately locate and sensitively detect prostate cancer. In addition, we reported discrepancies between diagnostic and pathological Gleason scores, and investigated whether prostate size had an effect on the cancer detection rate. MATERIALS AND METHODS: This retrospective diagnostic accuracy study compares the results of primary transperineal biopsies with the radical prostatectomy pathology of 414 consecutive patients treated at a single institution between November 2002 and August 2010. RESULTS: The average sensitivity and specificity for the detection of cancer in all prostates across all biopsy zones was 48% (95% CI 42.6-53.4) and 84.1% (95% CI 80-88.2), respectively. There was a statistically significant decrease in the sensitivity of transperineal biopsy in larger prostates (t11=4.687, p=0.001). The overall Kappa value was 0.255 (95% CI 0.212-0.298). Grading concordance between biopsy and pathology specimens was achieved in 65.7% of patients. Upgrading of Gleason scores occurred in 25.6% of patients and downgrading occurred in 8.8%. CONCLUSIONS: Our current transperineal biopsy method has only demonstrated fair agreement with the histopathology findings of the corresponding radical prostatectomy specimens. This finding is most likely due to the small, multifocal nature of prostate cancer in the patient series. The cancer detection rate was lower in larger prostates. Thus, clinicians may consider increasing the number of cores in larger prostates as a strategy to improve cancer detection.

BACKGROUND: Surgical resection of pulmonary metastases from renal cell carcinoma (RCC) has been demonstrated in recent studies to produce good long-term survival outcomes. Radiofrequency ablation (RFA) may offer an alternative treatment option for this group of patients, especially for those who are unable to have surgery. METHODS: Nine patients had a total of 23 pulmonary metastases treated with percutaneous RFA under fluoro-computed tomography (CT) guidance. Patients underwent routine overnight hospitalization and monitoring for other potential complications. CT scans were performed at 1 month after the procedure and at 3-monthly intervals. RESULTS: A total of 25 ablations were performed to 23 pulmonary metastases for our nine patients in 12 RFA sessions. No patient died within 30 days of the procedure. Five of the 12 procedures resulted in a pneumothorax (42%) and 3 required insertion of a Pleurocath. One patient had a bronchopulmonary fistula with an associated small pleural effusion and one patient had pneumonia. Of the 25 ablations, 14 lesions had decreased in size (56%), 1 was stable in size (4%), and 9 had increased in size (36%). One patient had deceased before adequate follow-up. Of the nine patients, two are alive and free of disease (mean survival time of 74 months), two are alive with disease (mean survival time of 16 months), and five have died of disease (mean survival time of 26.2 months). CONCLUSION: RFA offers a treatment alternative for local tumor control, particularly in selected patients with multiple, small lesions who are unsuitable for pulmonary resections.
