Arteriovenous malformations are frequently found in the head and neck, and are occasionally associated with congenital syndromes. They are rarely reported in the foot and ankle; however, when encountered in these particular locations, they may become painful and interfere with ambulation. Because of the lack of literature on pedal arteriovenous malformations, they remain enigmatic when encountered clinically. They form as a result of atypical development of the vascular system during embryogenesis. The identification, diagnosis, and treatment of an arteriovenous malformation can be challenging, because it may present similarly to more frequent soft-tissue pathologies in podiatric practice. These include fibroma, lipoma, ganglion cyst, or proteinaceous cyst. They have unpredictable behavior and a high recurrence rate. Failure to recognize and treat an arteriovenous malformation appropriately could result in ulceration, hemorrhage, and amputation. The identification and diagnosis must be accompanied with a full vascular work-up to determine the magnitude, flow, and extent of the lesion. After vascular work up, conservative, and surgical treatment options can be explored. This is an unusual case report of an arteriovenous malformation of the plantar foot that was previously misdiagnosed, and later presented to our facility for a second opinion. The steps taken for identification, diagnosis, and treatment are discussed along with surgical technique for excision of an arteriovenous malformation with successful outcome at 1 year follow-up. This case report will provide clinicians with armamentarium for diagnosis, workup, and treatment, when considering arteriovenous malformation in the differential diagnosis.The COVID-19 pandemic-related constraints on healthcare access have raised concerns about adverse outcomes from delayed treatment, including the risk of cancer progression and other complications. Further, concerns were raised about a potentially significant backlog of patients in need of cancer care due to the pandemic-related delays in healthcare, further exacerbating any potential adverse outcomes. Delayed access to surgery is particularly relevant to urologic oncology since one-third of new cancers in men (20% overall) arise from the genitourinary (GU) tract and surgery is often the primary treatment. Herein, we summarize the prepandemic literature on deferred surgery for GU cancers and risk of disease progression. The aforementioned data on delayed surgery were gathered in the context of systemic delays present in certain healthcare systems, or occasionally, due to planned deferral in suboptimal surgical candidates. These data provide indirect, but sufficient insight to develop triage schemas for prioritization of uro-oncological cases. Herein, we outline the extent to which the pandemic-related triage guidelines had influenced urologic practice in various regions. To study the adverse outcomes in the pandemic-era, a survey of urologic oncologists was conducted regarding modifications in their initial management of urologic cancers and any delay-related adverse outcomes. While the adverse effects directly from COVID-19 related delays will become apparent in the coming years, the results showing short-term outcomes are quite instructive. AF-353 Since cancer care was assigned a higher priority at most centers, this strategy may have avoided significant delays in care and limited the anticipated negative impact of pandemic-related constraints.Neonatal immunisation includes vaccination in the first 4 weeks of life (Neonatal period) as well as in high-risk preterm infants in the first few months (until 44 weeks corrected gestational age). Neonates have an immature immune system, which renders them highly susceptible to life-threatening infections. This highlights the importance of vaccination in this vulnerable population; however, at the same time also making it challenging because of their inability to generate a protective immune response. Other challenges include interference from maternal antibodies and excessive skewing towards T Helper Cell Type 2 (Th2) immunity. Despite these challenges, several vaccines have been developed and proven safe and effective at birth. Presently, there are 3 vaccines - Hepatitis B vaccine, Bacillus Calmette-Guerine (BCG) and Oral Polio vaccine (OPV) widely used in neonates, which provides evidence that certain antigen-adjuvant combinations can elicit protective neonatal responses. This review focusses on current vaccinations in neonates, including preterm infants and highlights some novel approaches to enhance neonatal vaccination.

Pediatric sacral neuromodulation (SNM) device duration before revision or removal is not well known. Furthermore, secondary surgeries serve as surrogates for key outcomes including complications and symptom improvement.

We sought to study the rate and causes of secondary surgeries in pediatric SNM patients.

We assessed our cohort of pediatric SNM patients for secondary surgeries (revision or removal). Baseline patient characteristics associated with secondary surgery were analyzed with Fisher's exact test. Kaplan-Meier analysis was used to describe secondary-surgery-free device survival.

187 pediatric patients underwent sacral neuromodulation at our institution between 2002 and 2019. 7 (4%) patients did not have a permanent device placed due to poor response during an externalized lead trial period, leaving 180 patients with permanent implanted devices. Over a median follow-up of 3.9 years (IQR 2.0 to 6.3), there were 154 total secondary surgeries. There were 83 device revisions, with 89% of revisionsear) follow-up.

Pediatric Leydig cell tumors (LCTs) represent approximately 4% of pre-pubertal testicular tumors and are known to cause precocious puberty secondary to testosterone production. While gonadotropins and testosterone are known to initiate spermatogenesis beginning in puberty, it is yet to be determined if a similar phenomenon is triggered by isolated testosterone production in prepubescent boys.

To determine if testicular pathology in pre-pubertal pediatric patients with LCTs exhibit spermatogenesis secondary to paracrine testosterone stimulation.

We reviewed patients who underwent orchiectomy for a testicular tumor from 2003-17. We included patients with LCTs and compared them to children with non-LCT pathology (teratomas and epidermoid cysts). We excluded other pathologies and tumors in pubertal patients. Data were collected on the presence of spermatogenesis on pathology, tumor markers and serum hormone results.

Orchiectomy for testicular tumors were completed in 66 patients, of which 20 were included in the non-LCT group and 9 in the LCT group.
