Why adolescents delay with presentation to hospital with acute testicular pain: a qualitative study
Background / Purpose
Adolescents have poor outcomes following testicular torsion directly attributable to delay
from onset of symptoms to presentation to hospital. The aim of this study was to investigate
the barriers to urgent presentation in young men.
Methods
Semi-structured interviews were undertaken with young men (11-19 years), using a topic
guide exploring issues surrounding testicular pain and health. Thematic analysis was
undertaken using a framework approach.
Results
Twenty-seven adolescents were recruited, data saturation was reached at sixteen
participants, median age 13.5 years (range 11-18). The process by which an adolescent
gets to hospital with testicular pain is slow. They must recognise the problem and alert their
parents, who then use a ‘watch and wait’ policy to assess need for medical review, often
leaving it ‘a day’ or overnight. Adolescent males do not engage with healthcare services
independently of their parents. Additional factors preventing early presentation include:
absence of knowledge about testicular pathology from adolescents and their parents;
concern from the young people about raising a false alarm and family concerns about
burdening healthcare services.
Conclusions
Recommendations include designing a testicular health education campaign for young men
and educating parents regarding the medical conditions where a ‘watch and wait’ policy may
be harmful to their child
Medical management of overactive bladder
Overactive bladder (OAB), as defined by the International Continence Society, is characterized by a symptom complex including urinary urgency with or without urge incontinence, usually associated with frequency and nocturia. OAB syndrome has an incidence reported from six European countries ranging between 12-17%, while in the United States; a study conducted by the National Overactive Bladder Evaluation program found the incidence at 17%. In Asia, the prevalence of OAB is reported at 53.1%. In about 75%, OAB symptoms are due to idiopathic detrusor activity; neurological disease, bladder outflow obstruction (BOO) intrinsic bladder pathology and other chronic pelvic floor disorders are implicated in the others. OAB can be diagnosed easily and managed effectively with both non-pharmacological and pharmacological therapies. The first-line treatments are lifestyle interventions, bladder training, pelvic floor muscle exercises and anticholinergic drugs. Antimuscarinics are the drug class of choice for OAB symptoms; with proven efficacy, and adverse event profiles that differ somewhat
Bipolar technology for transurethral prostatectomy.
Bipolar electrosurgical technology has gained worldwide attention with various companies introducing devices, such as the Gyrus PlasmaKinetic™ Tissue Management System (Gyrus ACMI, MN, USA) and the Olympus(®) UES-40 Surgmaster generator (Olympus, Tokyo, Japan), which is aimed at minimizing the morbidity of standard monopolar transurethral resection of the prostate (TURP), whilst also maintaining efficacy and durability. The Gyrus PlasmaKinetic System effectively controls bleeding, resulting in a clear operative field; it greatly reduces risk of transurethral resection syndrome, thus providing a new option among minimally-invasive surgical treatments for benign prostatic hyperplasia. In a meta-analysis of head-to-head comparisons between the monopolar and bipolar TURP, the operation times, transfusion rates, retention rates after catheter removal and urethral complications did not differ significantly. Irrigation and catheterization duration was significantly longer with monopolar TURP
Emphysematous pyelonephritis.
Emphysematous pyelonephritis (EPN) is a severe necrotizing infection of the renal parenchyma. The clinical course of EPN can be severe and life-threatening if not recognized and treated promptly. Most of the information has been from case reports, a few large series have also been reported. Using an evidence-based approach, this review describes the pathogenesis, classification, complications, and management of EPN. Emphysematous pyelonephritis (EPN) is an acute severe necrotizing infection of the renal parenchyma and its surrounding tissues that results in the presence of gas in the renal parenchyma, collecting system, or perinephric tissue. The cause for mortality in EPN is primarily due to septic complications. Up to 95% of the cases with EPN have underlying uncontrolled diabetes mellitus. The risk of developing EPN secondary to a urinary tract obstruction is about 25-40%. There are three classifications of EPN based on radiological findings. Acute renal failure, microscopic or macroscopic haematuria, severe proteinuria are other positive findings in EPN. Escherichia coli is the most common causative pathogen with the organism isolated on urine or pus cultures in nearly 70% of the reported cases. A plain radiograph shows an abnormal gas shadow in the renal bed raising the suspicion whereas an ultrasound scan or computed tomography (CT) will confirm the presence of intra-renal gas thus supporting the diagnosis of EPN. Gas may extend beyond the site of inflammation to the sub capsular, perinephric and pararenal spaces. In some cases, gas was found to be extending into the scrotal sac and spermatic cord. Subsequent case studies have shown patients being successfully treated with PCD when used in addition to medical management, with significant reduction in the morality rates. PCD should be performed on patients who have localized areas of gas and functioning renal tissue is present. The treatment strategies include MM alone, PCD plus MM, MM plus emergency nephrectomy, and PCD plus MM plus emergency nephrectomy. In small proportion of patients managed with MM and PCD, subsequent nephrectomy will be required and in these patients the reported mortality is 6.6% Nephrectomy in patients with EPN can be simple, radical or laparoscopic
