Diabetic foot ulcers present across the spectrum of nonhealing wounds, be it acute or many months duration. There is developing literature highlighting that despite this group having high caloric intake, they often lack the micronutrients essential for wound healing. This study reports a retrospective cohort of patients’ micro- and macro-nutritional state and its relationship to amputation. A retrospective cohort was observed over a 2-month period at one of Australia’s largest tertiary referral centers for diabetic foot infection and vascular surgery. Patient information, duration of ulcer, various biochemical markers of nutrition and infection, and whether the patient required amputation were collected from scanned medical records. A cohort of 48 patients with a broad-spectrum of biochemical markers was established. Average hemoglobin A1c (HbA1c) was 8.6%. A total of 58.7% had vitamin C deficiency, including 30.4% with severe deficiency, average 22.6 Ł} 5.8 μmol/L; 61.5% had hypoalbuminemia, average albumin 28.7 Ł} 2.5 g/L. Average vitamin B12 was 294.6 Ł} 69.6 pmol/L; 57.9% had low vitamin D, average 46.3 Ł} 8.3 nmol/L. Basic screening scores for caloric intake failed to suggest this biochemical depletion. There was a 52.1% amputation rate; biochemical depletion was associated with risk of amputation with vitamin C ( P < .01), albumin ( P = .03), and hemoglobin ( P = .01), markedly lower in patients managed with amputation than those managed conservatively. There was no relation between duration of ulceration and nutrient depletion. Patients with diabetic foot ulceration rely on multidisciplinary care to optimize their wound healing. An important but often overlooked aspect of this is nutritional state, with micronutrients being very important for the healing of complex wounds. General nutritional screening often fails to identify patients at risk of micronutrient deficiency. There is a high prevalence of vitamin deficiency in patients with diabetic foot ulcers. This presents an excellent avenue for future research to assess if aggressive nutrient replacement can improve outcomes in this cohort of patients.

Malignant epithelioid glioneuronal tumor is a rare high-grade, aggressive brain tumor that shows both glial and neuronal differentiation on histopathology but is not included in the current World Health Organization classification. The neuroimaging appearance is variable but may be secondary to the size of the mass and/or location of the tumor. In our series, all epithelioid glioneuronal tumors were encountered in the supratentorial space and included pineal, temporal, and extratemporal lobar cerebral hemisphere locations. When large, the tumors demonstrate cystic degeneration and necrosis, hemorrhage, contrast enhancement, and regions of low apparent diffusion coefficient scalars consistent with patterns seen with other high-grade pediatric brain tumors. The tumors also have a propensity to spread into the meninges at presentation and for distant CSF spread on follow-up imaging.

Introduction: We aimed to describe the presentation, investigations, and management of patients with urethral diverticula and to review the importance of magnetic resonance imaging (MRI) in the diagnosis and surgical management of urethral diverticula. Methods: This was a retrospective review of female patients who underwent urethral diverticulectomies. This study was approved by the Research Ethics review board. Data was collected on patient demographics, presenting symptoms, investigations performed, operative technique, and minimum of two-year followup. Results: A total of 17 patients were included in this study, with a median age was 43 years. Most patients (70%) presented with a palpable vaginal lump; 64% presented with either lower urinary tract symptoms (LUTS) or recurrent urinary tract infections (UTIs). Patients underwent a preoperative MRI, which demonstrated that 59% of diverticula were distal and 53% were locally round. These imaging findings were consistent with the operative findings. MRI also demonstrated communication between the urethral diverticulum and the urethral lumen in 80% of cases, compared to only 47% endoscopically. Conclusions: The most common presentation of a woman with a urethral diverticulum is with either a palpable vaginal lump, LUTS, or recurrent UTIs. A high index of suspicion is required. Pelvic MRI appears to be an ideal imaging modality for the diagnosis of urethral diverticulum. A preoperative MRI is important to exclude alternative pathologies, appropriately counsel the patient, and assist with the surgical planning.

Background: Extracorporeal shockwave lithotripsy (SWL) is still an important option in the treatment of renal tract stones. SWL is not without its limitations and alternatives should be considered. This study investigates the referral data to a new SWL planning meeting to identify reasons why SWL was not offered.Methods: A review of 12 months of data prospectively collected at a weekly stone meeting was supplemented with a retrospective chart analysis to identify the source of all referrals for SWL. The principal reason for diverting a patient to other stone management was noted.Results: 142 patients (median age 52 years) were referred for SWL over the 12-month period. SWL was not recommended in 40 (28.2%) patients. SWL was most commonly contraindicated due to excessive stone size±position (32.5%), anatomical complexity (25.0%) and radiolucency on x-ray (10.0%). The majority of patients who were diverted away from SWL were referred from an emergency department (32.5%) and the general urology clinics (20.0%).Conclusions: A significant portion of patients referred for SWL prove unsuitable for this method of stone clearance. This highlights an educational gap amongst clinicians regarding the indications and more importantly contraindications for SWL. Only 6.3% of total referrals originated from general practice suggesting a lack of awareness of the process of direct referral for SWL. Improving this with guidelines will relieve demand in outpatient clinics and help streamline patient care.
