INTRODUCTION: Few practice improvement registries exist that describe opportunities to improve intraosseous (IO) use. The goal of this project was to assess the success rate of the procedure by emergency nurses and identify opportunities to improvement. Secondary goals were to assess success rates based on clinician type, age of patient, and procedural factors. METHODS: Emergency nurses assigned to the resuscitation area of a tertiary care emergency department completed an education module and skill lab on IO placement...

The intrapetrous facial nerve has the second longest intraosseous course of all cranial nerves, after the mandibular nerve. But it is by far the most complex considering the anatomical structures closely related to it. The auditory and vestibular portions of the inner ear, the dura of the middle fossa and posterior fossa, the sigmoid sinus and jugular bulb, and the internal carotid artery are close enough to merit attention. This article includes an anatomical study on 100 temporal bones with anatomical references as seen from the middle fossa and from the transmastoid approaches that may help identifying the facial nerve and protecting surrounding structures...

OBJECTIVES: Antibody p40, which recognizes exclusively ΔNp63 but not TAp63, has shown diagnostic utility in salivary gland and sinonasal tract malignancies. Although p63 immunophenotypic characterization of odontogenic lesions has been reported, p40 expression has not been previously studied. We aimed to study p40 immunoreactivity in odontogenic tumors (OTs) and odontogenic cysts (OCs) and to investigate possible discriminatory properties of the combined p63/p40 immunoprofile in OTs and OCs...

Background: Treatment of teeth affected with molar incisor hypomineralization (MIH) in young patients is challenging due to chronic subclinical pulpal inflammation caused by porous enamel and exposed dentin. Hypersensitivity of the teeth and difficulty in achieving local anesthesia due to altered nerve potential affects the successful completion of the treatment. Aim: The aim of the study was to compare the anesthetic efficacy of the intraosseous (IO) anesthetic technique with conventional local infiltration technique in anesthetizing first permanent molars (FPMs) affected by MIH for restorative procedures in children...

This report presents a case of cervical pneumatocysts as an incidental finding on cone-beam computed tomography. Pneumatocysts are gas-containing lesions of unknown etiology. They usually present in the ilium or sacrum, adjacent to the sacroiliac joint. In the literature, 21 case reports have described cervical pneumatocysts. Cervical pneumatocysts should be differentiated from other lesions, such as osteomyelitis, osteonecrosis, and neoplasms, as well as post-traumatic and post-surgical cases. Computed tomography, cone-beam computed tomography, and magnetic resonance imaging are appropriate tools to diagnose cervical pneumatocysts...

Emphysematous osteomyelitis, characterized by intraosseous gas, is a rare but potentially fatal condition that requires prompt diagnosis and aggressive therapy. Causative organisms are members of the bacterial family Enterobacteriaceae or anaerobes in most cases and significant comorbidities such as diabetes mellitus and malignancy, may predispose an individual to the development of emphysematous osteomyelitis. We report a case of extensive emphysematous osteomyelitis via hematogenous spread from Klebsiella pneumoniae liver abscess, complicated by gas-containing abscesses in adjacent soft tissues and epidural space, and multiple systemic septic emboli in a diabetic patient...

BACKGROUND: Intraosseous lipomas occurring within the skull is rare. Currently, the known locations include frontal bone, parietal bone, temporal bone and ethmoid bone. Thus far, we have found only 12 cases of lipoma at the top of the forehead on the skull, and only 2 cases of recurrent intraosseous lipoma have been reported. The intraosseous lipoma patient described in this article is a 3-year-old male child, the youngest of the 12 known cases of intraosseous lipoma of the skull, and the patient had repeated relapses...

Sacral tumors are one of the most challenging lesions of the spine to study and manage. Surgical resection techniques are often difficult due to the regional anatomy, in addition to tumor involvement of neural and structural elements. The surgical goals are influenced by tumor pathology but this can be made more complicated by a difficult diagnostic process. The authors present the rare entity of a sacral lipoma and the radiological and histological features which highlight this condition.

BACKGROUND: Primary pulmonary meningiomas are very rare, and primary intraosseous meningiomas outside the head and neck region have not yet been reported. We report an extremely unusual case of concurrent meningiomas arising in the pulmonary parenchyma and vertebral bone. CASE PRESENTATION: A 40-year-old Asian woman presented with a destructive lesion of the lumbar vertebral bone and a small nodule in the right lung. Five years later, both lesions slightly increased in size...

We report an atypical case of an epidermoid cyst associated with a skull defect to emphasize the diagnostic utility of bedside ultrasonography for the evaluation of subcutaneous scalp nodules. A 24-year-old woman presented with what appeared to be a benign cyst on the right parietal scalp. The cyst was first noticed one year prior to presentation and caused only mild irritation. Upon excision of the cyst, a notable calvarial defect was found in the frontoparietal bone and surgical excision was suspended. Head and brain imaging was performed confirming the calvarial defect with mild mass effect on the brain...

An understanding of the anatomy and function of the skull base venous channels is fundamentally important for safe performance of endoscopic surgery for skull base lesions. This review focuses on four skull base venous channels-namely, the intercavernous sinuses, basilar plexus, osseous veins, and inferior petroclival vein-because these have been less recognized by neurosurgeons than other major venous channels such as the inferior petrosal sinus. We reviewed the literature concerning these four venous channels and discussed their anatomy and function...

BACKGROUND: Distal chevron metatarsal osteotomy bunionectomy is a commonly performed procedure for the treatment of mild to moderate hallux valgus. We continue to use the intraosseous sliding osteotomy plate system for fixation of the distal metatarsal osteotomy. With the addition of the Akin osteotomy, we are able to obtain reliable, reproducible correction with better cosmesis and increased patient satisfaction for more advanced deformities. METHODS: We prospectively evaluated 138 (145 feet) consecutive patients who underwent double osteotomy bunionectomy using the intramedullary plate system and 3...

While intraosseous cysts have been described in the paleopathological literature, it is rare to find reports concerning effects of soft tissue cysts, although they are relatively common in clinical contexts. Here we present plausible evidence of an extraosseous paralabral cyst, seen in an adult scapula from a Late Intermediate period commingled tomb (ca. AD 1200) at the northern highland site of Marcajirca, Ancash, Peru. The scapula demonstrated a smooth-sided concave depression at the spinoglenoid notch. The depression was notable for its regular appearance, with no bone deposition or destruction...

Primary intraosseous carcinoma (PIOC) is a rare but aggressive type of odontogenic tumour arising within the jawbone. Diagnosis criteria and treatment strategy remain difficult and controversial. The present study aimed to clarify the clinicopathological features and determine prognostic factors in management of PIOC. A retrospective study of 30 patients with PIOC, treated at the Hospital of Stomatology of Sun Yat-sen University between 2009 and 2017, was conducted. Clinical, histopathological and treatment modality data were collected...

Mobile stroke units offer improved time to administration of thrombolytics for ischemic stroke patients. Acquisition of intravenous (IV) access, however, can be challenging in the pre-hospital environment leading to treatment delays. Intraosseous (IO) access is commonly used in the pre-hospital setting for a variety of conditions and may serve as a viable means for tPA (tissue plasminogen activator) administration. We describe 3 cases in which tPA was administered via IO access on a mobile stroke unit as part of the Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services (BEST-MSU) trial...
