RESUMO

Purpose: Low-dose-rate (LDR) brachytherapy in young men remains controversial amongst urologists due to their concerns regarding long-term biochemical control and treatment-related toxicities. The purpose of this study was to evaluate the treatment outcomes of men under 60 years of age who underwent LDR brachytherapy with iodine-125 (125I) for clinically localized low- to intermediate-risk prostate cancer. Material and methods: All consecutive patients with clinically localized prostate cancer treated at our institution from 2003 to 2016 with 125I monotherapy were included in the study. Prescription dose was 145.0 Gy modified peripheral loading (MPD). All patients were assessed for biochemical progression-free survival using Phoenix definition (nadir +2 ng/ml), clinical progression-free survival, overall survival (OS), and any associated treatment toxicity. Results: A total of 161 patients were included, with a median follow-up of 6.8 years (range, 3-14.54 years). Median age at implant was 57 years (range, 53-59 years). Mean prostate specific antigen (PSA) level at diagnosis was 4.43 ng/ml (SD = 2.29). Majority of men had low-risk prostate cancer (70.2%). Biochemical progression-free survival at 8 years was 94% for the entire cohort. Median PSA at 4 years was 0.169 (IQR, 0.096-0.360), with 45% of patients having a PSA greater than 0.2. OS was 96.9%, with 5 deaths reported but only one was secondary to prostate cancer. Late grade > 2 genitourinary toxicities were reported in 18 patients (11.2%). Three patients (1.9%) developed secondary cancers, all considered unrelated to their LDR brachytherapy. Conclusions: With excellent long-term treatment outcomes and minimal associated toxicities, our results showed that LDR brachytherapy can be an effective treatment of choice in younger men.

RESUMO

OBJECTIVE: The ultra-high risk clinical phenotype is associated with substantial distress and functional impairment and confers a greatly enhanced risk for transition to full-threshold psychosis. A range of interventions aimed at relieving current symptoms and functional impairment and reducing the risk of transition to psychosis has shown promising results, but the optimal type and sequence of intervention remain to be established. The aim of this study was to determine which intervention was most effective at preventing transition to psychosis: cognitive therapy plus low-dose risperidone, cognitive therapy plus placebo, or supportive therapy plus placebo. METHOD: A double-blind, randomized, placebo-controlled 12-month trial of low-dose risperidone, cognitive therapy, or supportive therapy was conducted in a cohort of 115 clients of the Personal Assessment and Crisis Evaluation Clinic, a specialized service for young people at ultra-high risk of psychosis located in Melbourne, Australia. Recruitment commenced in August 2000 and ended in May 2006. The primary outcome measure was transition to full-threshold psychosis, defined a priori as frank psychotic symptoms occurring at least daily for 1 week or more and assessed using the Comprehensive Assessment of At-Risk Mental States. Secondary outcome measures were psychiatric symptoms, psychosocial functioning, and quality of life. RESULTS: The estimated 12-month transition rates were as follows: cognitive therapy + risperidone, 10.7%; cognitive therapy + placebo, 9.6%; and supportive therapy + placebo, 21.8%. While there were no statistically significant differences between the 3 groups in transition rates (log-rank test P = .60), all 3 groups improved substantially during the trial, particularly in terms of negative symptoms and overall functioning. CONCLUSIONS: The lower than expected, essentially equivalent transition rates in all 3 groups fail to provide support for the first-line use of antipsychotic medications in patients at ultra-high risk of psychosis, and an initial approach with supportive therapy is likely to be effective and carries fewer risks.

RESUMO

Secondary tumoral calcinosis is a rare disorder that is most prevalent in patients with chronic renal failure. It is characterized by lobular densely calcified masses confined to the soft tissue, generally at the extensor surface of a joint in the anatomic distribution of a bursa. We describe a case of a 38-y-old man undergoing dialysis who presented with pyrexia of unknown origin and raised inflammatory markers but was otherwise asymptomatic. A (67)Ga scan was performed, on which an incidental diagnosis of secondary tumoral calcinosis was made.

RESUMO

BACKGROUND: Hospital readmissions are common and costly. A recent previous hospitalization preceding the index admission is a marker of increased risk of future readmission. OBJECTIVES: To identify factors associated with an increased risk of recurrent readmission in medical patients with 2 or more hospitalizations in the past 6 months. DESIGN: Prospective cohort study. SETTING: Australian teaching hospital acute medical wards, February 2006-February 2007. PARTICIPANTS: 142 inpatients aged ≥ 50 years with a previous hospitalization ≤ 6 months preceding the index admission. Patients from residential care, with terminal illness, or with serious cognitive or language difficulties were excluded. VARIABLES OF INTEREST: Demographics, previous hospitalizations, diagnosis, comorbidities and nutritional status were recorded in hospital. Participants were assessed at home within 2 weeks of hospital discharge using validated questionnaires for cognition, literacy, activities of daily living (ADL)/instrumental activities of daily living (IADL) function, depression, anxiety, alcohol use, medication adherence, social support, and financial status. MAIN OUTCOME MEASURE: Unplanned readmission to the study hospital within 6 months. RESULTS: A total of 55 participants (38.7%) had a further unplanned hospital admission within 6 months. In multivariate analysis, chronic disease (adjusted odds ratio [OR] 3.4; 95% confidence interval [CI], 1.3-9.3, P = 0.002), depressive symptoms (adjusted OR, 3.0; 95% CI, 1.3-6.8, P = 0.01), and underweight (adjusted OR, 12.7; 95% CI, 2.3-70.7, P = 0.004) were significant predictors of readmission after adjusting for age, length of stay and functional status. CONCLUSIONS: In this high-risk patient group, multiple chronic conditions are common and predict increased risk of readmission. Post-hospital interventions should consider targeting nutritional and mood status in this population.

RESUMO

We present a case of smothering of a 2-year-old male infant by his schizophrenic mother who was having a psychotic episode. In addition to the initial autopsy findings of conjunctival petechial hemorrhages, facial linear abrasions and bruises, and mucosal abrasions and bruises, expert odontologic examination revealed indentations of the cusps of central incisors and molars, providing additional evidence of smothering. The postmortem and toxicological examination revealed features of forced quetiapine administration. The case presented is the first case of forced administration of quetiapine described. Our case also highlights the value of expert forensic odontological examination.
