RESUMEN
BACKGROUND: Procedural anxiety was anticipated in children 5-11 years during the COVID-19 vaccine rollout in Victoria, Australia, as children in this age group receive few routine vaccines. Therefore, the Victorian state government designed a tailored, child-friendly vaccine program. This study aimed to assess parental satisfaction with elements of the bespoke vaccination pathway. METHODS: The Victorian government and state-run vaccination hubs in Victoria facilitated an online immunisation plan to help parents identify their child's support needs, and utilised experienced paediatric staff and additional supports for children with severe needle distress and/or disability. All parents/guardians of children 5-11 years who received a COVID-19 vaccine in a vaccination hub were sent a 16-item feedback survey via text message. RESULTS: Between 9 February and 31 May 2022 there were 9203 responses; 865 children (9.4%) had a first language other than English, 499 (5.4%) had a disability or special needs, and 142 (1.5%) were Aboriginal or Torres Strait Islander. Most parents (94.4%; 8687/9203) rated their satisfaction with the program as very good or excellent. The immunisation plan was used by 13.5% (1244/9203) of respondents, with usage more common for Aboriginal or Torres Strait Islander children (26.1%; 23/88) or families with a first language other than English (23.5%; 42/179). The child-friendly staff (88.5%, 255/288) and themed environment (66.3%, 191/288) were the most valued measures for vaccination. Additional support measures were required by 1.6% (150/9203) of children in the general population and 7.9%, (17/261) of children with a disability and/or special needs. CONCLUSION: A tailored COVID-19 vaccination program for children 5-11 years, with additional support for children with severe needle distress and/or disability, had high parental satisfaction. This model could be utilised for COVID-19 vaccination in pre-school children and for routine childhood vaccination programs to provide optimal support to children and their families.

BACKGROUND: The mounting pressure on the Australian healthcare system is driving a continual exploration of areas to improve patient care and access and to maximize utilization of our workforce. We hypothesized that there would be support by anesthetists employed at our hospital for the design, development, and potential implementation of an anesthesia-led nurse practitioner (NP) model for low-risk colonoscopy patients. METHODS: We conducted a cross-sectional, mixed methods study to ascertain the attitudes and acceptability of anesthetists towards a proposed anesthesia-led NP model for low-risk colonoscopy patients. An online survey using commercial software and theoretical questions pertaining to participants' attitudes towards an anesthesia-led NP model was e-mailed to consultant anesthetists. Participants were also invited to participate in a voluntary 20-min face-to-face interview. RESULTS: A total of 60 survey responses were received from a pool of 100 anesthetists (response rate = 60%, accounting for 8.04% margin of error). Despite the theoretical benefits of improved patient access to colonoscopy services, most anesthetists were not willing to participate in the supervision and training of NPs. The predominant themes underlying their lack of support for the program were a perception that patient safety would be compromised compared to the current model of anesthesia-led care, the model does not meet the Australian and New Zealand College of Anesthetists guidelines for procedural sedation and analgesia, and the program may be a public liability prone to litigation in the event of an adverse outcome. Concerns about consumer acceptance and cost-effectiveness were also raised. Finally, participants thought the model should be pilot tested to better understand consumer attitudes, logistical feasibility, patient and proceduralist attitudes, clinical governance, and, importantly, patient safety. CONCLUSIONS: Most anesthetists working in a single-center university hospital did not support an anesthesia-led NP model for low-risk colonoscopy patients. Patient safety, violations of the current Australian and New Zealand College of Anesthetists guidelines on procedural sedation, and logistical feasibility were significant barriers to the acceptance of the model.

OBJECTIVE: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a heterogeneous inherited disease characterized by renal and extrarenal manifestations with progressive fluid-filled cyst development leading to end-stage renal disease. Our aim was to evaluate the prevalence of obstructive urological disease in ADPKD patients and possible associations with endothelial dysfunction, nutritional, metabolic and inflammatory markers. PATIENTS AND METHODS: The study included ADPKD patients and control group, who carried out uroflowmetry, an assessment of renal function, metabolic and nutritional parameters and an evaluation of endothelial dysfunction and atherosclerotic markers, such as Renal Resistive Index (RRI), Intima-Media Thickness (IMT) and Flow-Mediated Dilation (FMD). RESULTS: We enrolled 37 ADPKD patients (20 males with 51.0 ± 14.3 years) and 34 control group (18 males with 60.7 ± 14.4 years). We showed a significant reduction in Max Flow Rate (Qmax) (p ≤ 0.001), age (p = 0.006), FMD (p = 0.023) and Voiding Volume (p = 0.053), in addition to a significant increase in Voiding Time and Diastolic Blood Pressure (p ≤ 0.001, p = 0.049; respectively) in ADPKD patients with respect to control group. Moreover, we found a negative correlation between Qmax and creatinine (r= -0.44, p = 0.007), RRI (r= -0.49, p ≤0.001) and intact Parathyroid Hormone (r = -0.329, p = 0.046), while we found a positive correlation between Qmax and MDRD (r = 0.327, p = 0.048) and between Voiding Time and serum uric acid (r= 0.34, p = 0.039) in ADPKD patients with respect to control group. CONCLUSIONS: In our study, we showed an elevated prevalence of urological functional diseases in ADPKD patients; therefore, we suggest to include uroflowmetry in the assessment of these patients, considering the non-invasiveness, repeatability and low cost of the exam. An early intervention could slow down the progression of renal damage and an early screening of the main cardiovascular risk factors could reduce the high morbidity and mortality in ADPKD patients.

Co-management and critical care outreach for high risk surgical patients have been proposed to decrease postoperative complications and mortality. We proposed that a clinical project with postoperative comanagement and critical care outreach, the Post Operative Surveillance Team: (POST), would be associated with decreased hospital length of stay. We conducted a retrospective before (control group) and after (POST group) audit of this hospital program. POST was staffed for four months in 2010 by two intensive care nurses and two senior registrars who conducted daily ward rounds for the first five postoperative days on high risk patients undergoing inpatient general or urological surgery. The primary endpoint was length of hospital stay and secondary endpoints were Medical Emergency Team (MET) calls, cardiac arrests and in-hospital mortality. There were 194 patients in the POST group and 1,185 in the control group. The length of stay in the POST group, median nine days (Inter-quartile range [IQR]: 5 to 17 days), was longer than the control group, median seven days (IQR: 4 to 13 days): difference two days longer (95.0% confidence interval [95.0% CI]: 1 to 3 days longer, P <0.001). There were no important differences in the proportion of patients having MET calls (16.0% POST versus. 13% control (P=0.25)) or mortality (2.1% POST versus 2.8% Control (P=0.82)). Our audit found that the POST service was not associated with reduced length of stay. Models of co-management, different to POST, or with different performance metrics, could be tested.

BACKGROUND: Vancomycin-resistant enterococcus (VRE) colonization and infection have increased at our hospital, despite adherence to standard VRE control guidelines. AIM: We implemented a multi-modal, hospital-wide improvement programme including a bleach-based cleaning-disinfection programme ('Bleach-Clean'). VRE colonization, infection and environmental contamination were compared pre and post implementation. METHODS: The programme included a new product (sodium hypochlorite 1000 ppm + detergent), standardized cleaning-disinfection practices, employment of cleaning supervisors, and modified protocols to rely on alcohol-based hand hygiene and sleeveless aprons instead of long-sleeved gowns and gloves. VRE was isolated using chromogenic agar and/or routine laboratory methods. Outcomes were assessed during the 6 months pre and 12 months post implementation, including proportions (per 100 patients screened) of VRE colonization in high-risk wards (HRWs: intensive care, liver transplant, renal, haematology/oncology); proportions of environmental contamination; and episodes of VRE bacteraemia throughout the entire hospital. FINDINGS: Significant reductions in newly recognized VRE colonizations (208/1948 patients screened vs 324/4035, a 24.8% reduction, P = 0.001) and environmental contamination (66.4% reduction, P = 0.012) were observed, but the proportion of patients colonized on admission was stable. The total burden of inpatients with VRE in the HRWs also declined (median percentage of colonized inpatients per week, 19.4% vs 17.3%, P = 0.016). Hospital-wide VRE bacteraemia declined from 14/2935 patients investigated to 5/6194 (83.1% reduction; P < 0.001), but there was no change in vancomycin-susceptible enterococcal bacteraemia (P = 0.54). CONCLUSION: The Bleach-Clean programme was associated with marked reductions in new VRE colonizations in high-risk patients, and VRE bacteraemia across the entire hospital. These findings have important implications for VRE control in endemic healthcare settings.

OBJECTIVE: No published studies focus on determining the frequency of dysrhythmias during pulmonary artery catheter removal by use of a standard technique. The objective was to assess the incidence and hemodynamic effect of dysrhythmias in patients who had recently undergone cardiac surgery (within 24 hours of when dysrhythmia was noted). METHODS: The study used an electrocardiogram recording by continuous rhythm strip during removal of the pulmonary artery catheter. Pulmonary artery catheters were removed by use of a standard procedure. Data were collected with respect to patients' serum potassium levels, acid-base status, and if they were receiving intravenous antiarrhythmic or inotropic drugs during the PAC removal procedure. RESULTS: One hundred pulmonary artery catheters were removed, with the following types of dysrhythmia recorded: 2 patients had self-terminating ventricular tachycardia with transient hypotension; 1 patient had supraventricular tachycardia without hypotension; 13 patients had isolated ventricular ectopic dysrhythmia without hypotension; 2 patients had isolated atrial ectopic dysrhythmia without hypotension; and 1 patient had isolated atrial ectopic dysrhythmia and 3-beat supraventricular tachycardia without hypotension. CONCLUSION: The use of a standard technique for pulmonary artery catheter removal demonstrated a 2% incidence of nonsustained ventricular tachycardia associated with transient hypotension. Fewer incidences of dysrhythmias were noted in the patients (4 of 29) who had abnormal serum potassium levels, abnormal pH, or pharmacologic association during catheter removal in comparison with those patients without this association (15 patients of 71). No statistically significant difference was noted in the incidence of dysrhythmia during pulmonary artery catheter removal between these 2 groups (chi(2) = 0.72, P =.39).

OBJECTIVES: To analyze the frequency and risk factors for urinary incontinence (UI) in Italy. METHODS: Eligible for this cross-sectional study were men aged >/=50 years and women aged >/=40, randomly identified among registered subjects of a network of general practitioners during the period March-October 1997. All subjects were invited by telephonic interview to determine the presence of UI, reported by the subjects as loss of urine in the last year. The subjects with UI were further questioned at home for evaluation of the type, degree and frequency of UI episodes. RESULTS: Of the 5,488 subjects interviewed (2,767 women and 2,721 men), 92 (3%) men and 316 (11%) women reported at least one episode of UI during the year before the interview. The frequence of UI increased with age both in men and women, being 2 and 11% in men and women, respectively, aged 50-60 years and 7 and 16% in those aged >/=70. Of the subjects with UI identified, 229 women and 64 men and a group of 289 subjects without UI were questionned at home using a detailed questionnaire. Six and 55% of men and women, respectively, reported stress incontinence, 20 and 12% urge incontinence and 20 and 24% mixed incontinence. The risk of UI increased with body mass index in women. A history of recurrent urinary infection was associated with UI in men and less markedly in women. No association emerged between education, smoking and alcohol or coffee consumption and risk of UI. Parity was directly associated with the risk of UI in women. CONCLUSIONS: The study offers a quantitative estimate of the prevalence of UI and its main risk factors in this Italian population.

At the Austin & Repatriation Medical Centre (A&RMC) an innovative approach was taken to improve the reliability of ICU bed availability for elective cardiac surgery patients. A cardiac surgery recovery unit (CSRU), a dedicated three bed area, was established within the Post Anaesthesia Care Unit (PACU) so as to deliver care to a group of patients that had previously been provided in the Intensive Care Unit (ICU). Derived benefits arising from this initiative include a reduction in the number of cardiac surgery cancellations for want of ICU beds, reduced length of stay of patients in the CSRU and in the Medical Centre, and an improvement in the level of knowledge and skills of PACU nurses in relation to caring for the specific needs of acutely ill patients.

BACKGROUND: In mini-invasive surgery for the treatment of urinary incontinence injectable substances such as politef, autologous fat or bovine collagen, which can increase urethral resistance or support the sphincteric one are particularly used. It's a simple procedure in which patients may undergo local anesthesia, in short time and in "day hospital" regimen. Collagen, used as an injectable bulking agent, is the gold standard for this surgical technique because of complete biocompatibility, no evidences of adverse immunogenic effects, foreign-body reaction, migration of injected material, and because of higher fluidity which allows the use of thin needles compared to Politef (polytetrafluoroethylene) where an injection device is requested. Bovine collagen is partially reabsorbed within 24-36 months and a reinjection is often necessary. Although autologous fat is cheaper than bovine collagen, its injection shows more difficulties due to the need of higher needle diameter and time to store and prepare the material to inject. METHODS: The results obtained by two different approaches: transurethral injection of collagen and periurethral injection of collagen have been studied. A total of 48 patients underwent collagen injection for treatment of urinary incontinence: 24 treated by transurethral approach and 24 by periurethral approach. Follow-up at 6, 12, 24 months after treatment includes: objective exam, PAD test, functional evaluation, complete urodynamic evaluation (uroflow, cystomanometry, LPP, pressure/flow study, UPP). RESULTS: No clinical differences between peri/trans-urethral approach were found although collagen injection via transurethral technique need fewer material, reducing cost of treatment: an efficacy of treatment in 80% of patients and restoration of a complete urinary continence in 50% of patients was obtained. Although no clinical differences were demonstrated between the two different sites of injection, transurethral approach can be used similarly in both sexes even if without a modified resector as "injection device" it's more difficult to inject collagen in the right position, at the level of bladder neck submucosa. Perineal approach, exclusive of female sex, realizes the procedure without bleeding of urethral mucosa and no waste of collagen, though a longer period of training by surgeon is requested. After four years of experience the authors agreed that with an adequate injection device (modified resector), transurethral approach should be preferred, thus depending on the possibility to inject collagen in a correct position, just under bladder neck mucosa, which is possible to manage with this technique, in order to reduce reabsorption process of collagen and to obtain a longer efficacy of treatment reducing the number of reinjection and of course the cost of treatment. Collagen injection should be considered within an integrated therapeutical picture together with topic and systemic pharmacotherapy, physiotherapy, not excluding surgery techniques such as implantation of an artificial sphincter device in man or a sling procedure in woman. CONCLUSIONS: The urethral collagen injection for the treatment of urinary incontinence is a safe, durable and valid technique to improve urinary continence through a non obstructive effect increasing urethral resistance. Performed under local anesthesia this procedure allows the treatment of patients who may not be candidates suitable for general anesthesia and conventional surgery.

OBJECTIVE: Different etiopathological mechanisms of enuresis are today under study, and different therapies and drugs have been proposed. The Italian Multicentric Trial was undertaken in twelve pediatric and urological centers in order to assess the efficacy of two of the most popular drugs, desmopressin (DDAVP) and oxybutynin. METHODS: 114 enuretic patients were enrolled in the study. After a 2-week observation period, 66 patients with primary monosymptomatic enuresis were treated with DDAVP, 30 micrograms/day intranasally, for 6 weeks, 48 patients with enuresis and voiding dysfunction were randomly assigned to a protocol with oxybutynin alone or oxybutynin plus DDAVP. The efficacy of the two drugs was measured in terms of reduction of wet nights per week during the 6-week treatment period and a 2-week follow-up period. Children with 0-3 dry nights/week were considered as nonresponders. RESULTS: Patients with monosymptomatic enuresis treated with DDAVP reported a significantly lower number of wet night during treatment than during the baseline period, with 79% showing a 'good' (6-7 dry nights/week) or 'intermediate' response (4-5 dry nights/week). Of the patients with diurnal voiding disturbances and enuresis, those treated with oxybutynin alone had a 54% success rate. The patients treated with both oxybutynin and DDAVP showed a better response, with a 71% rate of success. CONCLUSIONS: The efficacy of the two drugs is confirmed in patients carefully selected on the clinical basis of voiding disturbances. In patients with enuresis and voiding dysfunction, the reduced urinary output and the lower bladder filling rate due to DDAVP can reduce uninhibited bladder contractions, thus enhancing the oxybutynin action.

OBJECTIVE: The objective of this double-blind, placebo-controlled urodynamic pressure/flow study was to assess the efficacy of short-term treatment with the alpha 1-blocker alfuzosin in outflow obstruction of patients with symptomatic benign prostatic hyperplasia (BPH). MATERIAL AND METHODS: Urodynamic pressure/flow parameters were assessed after 2 weeks of placebo run-in, 4 weeks of placebo (47 patients) or 2.5 mg t.i.d. alfuzosin treatment (47 patients), followed by an 8-week extension period with alfuzosin (single-blind). RESULTS AND CONCLUSION: Four weeks of alfuzosin treatment significantly increased maximum flow (+29.0%) and decreased detrusor pressure at maximum flow (-30.2%), detrusor opening pressure (-39.4%) and maximum detrusor pressure (-28.7%). Short-term alfuzosin treatment improved outflow conditions in BPH by reducing prostatic urethral obstruction.

Between 1989 and 1993 96 patients (89 males and 7 females) affected with invasive neoplasms of the bladder underwent surgery consisting of the creation of an orthotopic ileal neobladder according to Studer et al., after radical cystectomy. Patient selection and details of the surgical procedure are described. An accurate follow-up of 3-60 months (mean: 28 months) is presented. There have been 6 perioperative deaths (6.2%) and 11 early complications, all directly related to the neobladder and requiring reoperation in 6 cases (6.2%). Late complications required rehospitalization in 23 cases (23.9%) and a second reoperation was necessary in 10 (10.4%). The urodynamic tests show that the neobladder assumes an average capacity at about 330 cm3 after 1 year. Pressure at maximum capacity decreases in time and ranges from 10 to 20 cm H2O at 2 years. After 1 year, the complete urinary continence rate by day is 97% and the stress incontinence rate is 22%. Night-time continence, instead, increases to 74% after 1 year and to 83% after 2 years. In female patients, the functional results were satisfactory thanks to careful patient selection and to the surgical procedure adopted. Twenty-four patients had disease progression; 17 of these patients with locally advanced neoplasms died. The authors believe that the orthotopic ileal continent reservoir can be a satisfactory solution after cystectomy for bladder cancer, offering the patients a better quality of life compared to other urinary diversions both in male and female patients.

We describe a surgical technique to conserve urinary continence in 7 women who underwent radical cystectomy with construction of an orthotopic ileal neobladder for infiltrating bladder carcinoma. The selection of the patients and the surgical procedure to preserve the anatomical and functional integrity of the female urethra are described. Followup ranged from 7 to 28 months. There were no postoperative deaths or serious clinical complications. The urinary continence rate was 100% during the day and 71% at night with micturition at regular 3-hour intervals. The vesical capacity varied from 250 to 400 cc and pressure at maximum capacity from 10 to 25 cm. water. Urinary flow was satisfactory and the urethral pressure profile showed a normal sphincteric mechanism at rest. Two patients died of metastases at 14 and 8 months postoperatively, and 5 are alive and disease-free. We believe that these results confirm the possibility of obtaining micturition in women via the urethra following radical cystectomy.

Benign prostatic hyperplasia (BPH) is a benign disease characterized in a high percentage by cervico-urethral disorders. With regard to the obstructive aspect, this is the result of two components: mechanic and dynamic. The mechanic component is a direct consequence of the obstruction caused by enlargement of the prostate gland and the urethral deformation. The dynamic, on the other hand, is derived from the increase in tone of the smooth muscle following stimulation by adrenoreceptor alpha, localized at the level of the bladder neck, prostatic urethra and prostatic capsule. The use of alpha blockers in the treatment of BPH has the goal of intervening in the effects of the obstruction acting on the dynamic components. The use of alpha-blockers drugs, as explained in published literature, shows more or less satisfactorily, a significant symptomatic improvement and consequently an improvement in the quality of life. But the use of alpha blocker presently available may be considered as an unspecific or primitive, strictly symptomatic treatment for irritative symptoms for those who desire to postpone surgery, or in the cases in which surgery is not recommended or refused by the patient, and finally, to prevent acute urinary retention while the patient is waiting for surgery.

We examined the relationship between cerebral magnetic resonance imaging (MRI) findings and urinary dysfunction in 70 consecutive patients with definite multiple sclerosis. MRI-weighted lesion scores for seven different brain regions were recorded according to the number and size of cerebral lesions. Thirty-two subjects (46%) had urinary symptoms and 38 (54%) were asymptomatic. Subjects with urinary symptoms exhibited greater overall functional disability and a higher midbrain MRI-weighted lesion score than asymptomatic patients. No statistically significant group differences were found for the other brain regions.

Prognostic factors in superficial transitional cell carcinoma of the bladder were assessed with histopathological and flow cytometry analysis in a series of 61 patients operated transurethrally between 1988 and 1990. In particular, we evaluated the usefulness of flow cytometry in order to identify patients who require a more accurate clinical follow-up or a more aggressive therapy. A multivariate analysis was done in 61 cases, considering patient age and sex, stage, grade and number of lesions (unifocal or multifocal), post-TUR therapy (therapy or not), and DNA ploidy (diploid/aneuploid). DNA pattern and number of recurrences were determinant for selecting risk cases for progression.
