BACKGROUND: Limited data exist regarding the safety of ultrasound-guided femoral nerve blockade (US-FNB) in patients with hip fractures treated with anti-Xa direct oral anticoagulants (DOAC). OBJECTIVES: To compare the safety outcomes of US-FNB to conventional analgesia in patients with hip fractures treated with anti-Xa DOAC. METHODS: This observational exploratory prospective study included 69 patients who presented to our emergency department (ED) in 3 years with hip fracture and who were treated with apixaban or rivaroxaban. Patients received either a US-FNB (n=19) or conventional analgesics (n=50) based on their preference and, and the presence of a trained ED physician qualified in performing US-FNB. Patients were observed for major bleeding events during and 30 days after hospitalization. The degree of preoperative pain and opioid use were also observed. RESULTS: We found no significant difference in the number of major bleeding events between groups (47.4% vs. 54.0%, P = 0.84). Degree of pain measured 3 and 12 hours after presentation was found to be lower in the US-FNB group (median visual analog scale of pain improvement from baseline of -5 vs. -3 (P = 0.002) and -5 vs.-4 (P = 0.023), respectively. Opioid administration pre-surgery was found to be more than three times more common in the conventional analgesia group (26.3% vs.80%, P < 0.0001). CONCLUSIONS: Regarding patients treated with Anti-Xa DOAC, US-FNB was not associated with an increase in major bleeding events compared to conventional analgesia, although it was an effective means of pain alleviation. Larger scale randomized controlled trials are required to determine long-term safety and efficacy.

Acute liver injury (ALI) in children is a life-threatening event, and a definitive etiology can be identified in approximately 50% of cases. Neuroblastoma amplified sequence (NBAS) gene mutations have been associated with a broad phenotypic spectrum of this disease, ranging from recurrent episodes of fever-induced liver injuries to multiorgan involvement, including frequent infections as well as skeletal and immunological abnormalities. Here, we describe an adolescent female with a confirmed compound heterozygous NBAS gene mutation who presented with an episode of ALI complicated by severe acute kidney injury (AKI). The kidney injury was most probably driven by an intrinsic insult, as noted by elevated neutrophil gelatinase-associated lipocalin levels and a kidney biopsy demonstrating severe tubular damage consistent with acute tubular necrosis. While the patient's liver function and mental status showed significant improvement with supportive care, recovery of kidney function was delayed, and the patient required acute hemodialysis. We suggest a causative relation between the NBAS gene mutation and severe AKI.

Varicella- zoster virus infection is an intriguing medical entity that involves many medical specialties including infectious diseases, immunology, dermatology, and neurology. It can affect patients from early childhood to old age. Its treatment requires expertise in pain management and psychological support. While varicella is caused by acute viremia, herpes zoster occurs after the dormant viral infection, involving the cranial nerve or sensory root ganglia, is re-activated and spreads orthodromically from the ganglion, via the sensory nerve root, to the innervated target tissue (skin, cornea, auditory canal, etc.). Typically, a single dermatome is involved, although two or three adjacent dermatomes may be affected. The lesions usually do not cross the midline. Herpes zoster can also present with unique or atypical clinical manifestations, such as glioma, zoster sine herpete and bilateral herpes zoster, which can be a challenging diagnosis even for experienced physicians. We discuss the epidemiology, pathophysiology, diagnosis and management of Herpes Zoster, typical and atypical presentations.
