We report the case of a 77-year-old woman presenting with an asymptomatic internal carotid artery (ICA) aneurysm arising at the skull base. The distal right extracranial ICA aneurysm presented as a challenging case due to difficulty in obtaining adequate surgical exposure and preserving the facial nerves present near the ICA aneurysm. Transcervical open repair with a team of vascular and otolaryngology surgeons was completed successfully. In this report, we detail the operative steps needed to complete this exposure and our perioperative management...

Although chronic osteomyelitis (COM) affecting the extremities is a frequently occurring disease, the incidence of squamous cell carcinoma (SCC) arising from COM is rare. Consequently, understanding the diagnosis, treatment and prognosis of such a disorder remains limited. In the present study, a case of COM-associated SCC was demonstrated. A 65-year-old woman arrived to the Southern Medical University Nanfang Hospital (Guangzhou, China) with multiple sinus tracts and skin ulcers in the distal part of her left thigh, persisting for over 50 years following an open pierce injury by an ox horn...

Achondroplasia (ACH) is a skeletal dysplasia characterized by short-limbed short stature caused by the gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. Activated FGFR3, which is a negative regulator of bone elongation, impairs the growth of long bones and the spinal arch by inhibiting chondrocyte proliferation and differentiation. Most patients with ACH have spinal canal stenosis in addition to short stature. Meclozine has been found to inhibit FGFR3 via drug repurposing. A 10-d treatment with meclozine promoted long-bone growth in a mouse model of ACH ( Fgfr3 ach mice)...

A bony mallet thumb is an extremely rare injury. An 82-year-old man fell from a standing height and injured his right thumb. Imaging examinations revealed a rare intra-articular fracture at the dorsal side of the base of the distal phalanx of the thumb called the bony mallet thumb. Conservative treatment was adopted initially; however, surgery was deemed necessary because of the redislocation of the bone fragment. Thus, the Ishiguro extension block technique was used, and three months later, satisfactory thumb function was achieved...

A direct sliding inguinal hernia descends through the superficial inguinal ring and encroaches on nearby organ structures, such as the bladder. This type of hernia is rare with a 2-5% incidence and occurs due to a weakness within the lower abdominal wall, usually associated with advancing age, that permits the distal colon to descend into the inguinal canal. Direct sliding inguinal hernias are a rare subset of inguinal hernias that require meticulous dissection due to their incorporation of nearby organs such as the bladder or colon...

We report a rare case of radial arteriovenous fistula in a middle-aged person after a successful transradial percutaneous coronary intervention. Early release of manual radial compression was the culprit behind the development of radial arteriovenous fistula. Early surgical repair of the radial arteriovenous fistula resulted in the complete resolution of distal forearm symptoms in the abovementioned patient. It is advised for young interventional cardiologists to apply a compressive bandage over the radial artery for a minimum period of one hour to get rid of this extremely rare complication...

The nectar spur is an important feature of pollination and ecological adaptation in flowering plants, and it is a key innovation to promote species diversity in certain plant lineages. The development mechanism of spurs varies among different plant taxa. As one of the largest angiosperm genera, we have little understanding of the mechanism of spur development in Impatiens . Here, we investigated the initiation and growth process of spurs of Impatiens uliginosa based on histology and hormone levels, and the roles of AUXIN BINDING PROTEIN ( ABP ) and extensin ( EXT ) in spur development were explored...

BACKGROUND Coracoid process fractures are uncommon and are often complicated by many types of shoulder girdle injuries. Previous reports have shown that osteosynthesis for isolated coracoid process fractures results in favorable outcomes and high bone union rates. However, owing to the rarity of coracoid process fractures combined with distal clavicle fractures, there are limited data to guide treatment strategies. We report a case of symptomatic nonunion despite performing osteosynthesis for fractures of the coracoid process and distal clavicle...

Spiral nematodes ( Helicotylenchus spp.) are polyphagous parasitic species exhibiting a broad host range and geographical distribution. However, their diversity in the cultivated regions of southern Alberta remains understudied. Hence, we conducted a comprehensive survey of the region's arable lands for the presence of spiral nematodes and revealed two Helicotylenchus species, H. crassatus and H. oscephalus . H. crassatus consisted of two distinct morphotypes: one morphotype had a conoid tail with slight ventral projection on the distal end, whereas the other had a broadly rounded tail...

Background: Endovascular techniques have gained preference over peripheral arterial bypass surgery due to their minimally invasive nature; however, endovascular treatments often show limited efficacy in arterial segments with a high atherosclerotic load. The use of atherectomy devices enables the removal of calcified plaque material and may promote arterial wall remodeling. This study assessed the technical success, safety, and feasibility of the BYCROSS® atherectomy device in femoropopliteal lesions. Methods: This single-center, retrospective cohort study analyzed elective patients undergoing BYCROSS® atherectomy for chronic peripheral arterial disease from March 2022 to May 2023...

Background: Hallux valgus (HV) morphological alterations impact forefoot kinetics. Surgery aims to restore both the morphology and function. Plantar pressure (PP) distribution systems represent an innovative additional tool to evaluate the hallux functional outcome after surgery in order to assess the hallux dorsiflexion, coupled with plantar flexion of the first ray. However, the literature reports limited evidence regarding the rebalancing of the plantar pressure distribution following surgery. The purpose of the present study was to examine the PP distribution in HV patients before and after a distal metatarsal osteotomy using a novel anatomically based protocol for in-shoe plantar load analysis during gait...
