Distraction Arthroplasty Combined with Autologous Bone Grafting for Diffuse-type Tenosynovial Giant Cell Tumour with Articular Cartilage Defect and Subchondral Bone Cysts: A Case Report.

Tenosynovial giant cell tumour encompasses a group of lesions that present with synovial differentiation and most commonly occur in the joint synovium, bursae, and tendon sheaths. Diffuse-type tenosynovial giant cell tumour, previously known as pigmented villonodular synovitis, is one of the most common benign soft tissue tumours of the foot and ankle and usually affects young adults. The differential diagnosis of diffuse-type tenosynovial giant cell tumours remains a clinical problem because its clinical symptoms are similar to those of inflammatory arthritis, including rheumatoid arthritis. Moreover, persistent diffuse-type tenosynovial giant cell tumours can lead to articular deterioration, including osseous erosions and subchondral bone cysts. Joint-preserving procedures are considered optimal for treating younger patients with ankle osteoarthritis because the indication of ankle arthrodesis and total ankle arthroplasty is limited. Thus, ankle distraction arthroplasty could be an alternative for treating diffuse-type tenosynovial giant cell tumour with articular deterioration in young patients. Here, we report about a woman in her early 30s who presented with ankle pain owing to a diffuse-type tenosynovial giant cell tumour with an articular cartilage defect and subchondral bone cysts. We performed ankle distraction arthroplasty combined with an autologous bone graft. A follow-up examination at 2 years revealed preservation of physical function and pain alleviation. These findings suggest that distraction arthroplasty is a viable treatment option for remedying the destruction of the articular cartilage and subchondral bone owing to diffuse-type tenosynovial giant cell tumours in young adults.

Evolving the SCAT5 for ruling out higher severity traumatic brain injuries-Can decision rules developed for emergency settings help?

Decision rules (e.g. Canadian CT Head Rule (CCHR) for adults and PECARN rule for children/adolescents) are used in emergency settings (ER rules) to assess traumatic brain injuries (TBI). The rules have a high sensitivity and near perfect negative predictive value that help to rule out more severe TBI. Which criteria should be added to the Sport Concussion Assessment Tool 5 (SCAT5) to reach the sensitivity of the ER rules and improve the utility of the SCAT5 for screening for higher severity head and brain injuries? : We performed a comparative analysis of the SCAT5 with the CCHR and PECARN rules. We compared the presence (yes or no) and comparative "face value" sensitivity (lower, identical, or higher) of the SCAT5 criteria to the ER rules criteria. Loss of consciousness, vomiting, severe/increasing headache, and seizure are SCAT "red flags" with similar or higher sensitivity compared to ER rules criteria. Five criteria had lower sensitivity or where absent from the SCAT. ER rules include any abnormality on the Glasgow coma scale (GCS <15), but only a "deterioration of the state of consciousness" is considered a "red flag" in the SCAT5. Persistent retrograde amnesia for more than 30 minutes, age >65, severity of the mechanism of injury, and signs of skull fractures are not mentioned in the SCAT5. : We identified 5 criteria that could inform the evolution the SCAT5 to improve its ability to rule out more severe TBI in a sideline assessment context.

Co-Existence of An Unusual Branching Pattern of Celiacomesenteric Trunk With Complete Common Mesentery in a 48-Year-Old Man: A Case Report.

Celiacomesenteric trunk (CMT) refers to the common origin of celiac trunk and superior mesenteric artery which is a very rare anatomical variation. CMT is incidentally diagnosed during angiography or abdominal computed tomography scanning. The diagnosis of CMT may inform surgical practice and prevent damage during invasive radiologic procedures, lowering thus the rate of iatrogenic errors. Complete common mesentery is in its turn a rarer congenital anomaly that arises from an abnormal rotation of primitive small intestine during embryonic development. We report a case of a 48-year-old man, suffering from chronic abdominal pain, and postprandial discomfort. The patient underwent an abdominal contrast-enhanced computed tomography that detected a CMT associated with common complete mesentery. According to our review of bibliography, this is the first case report to simultaneously report both congenital anomalies (CMT and common complete mesentery). Furthermore, the CMT described here has not been described in previous classifications and represent a novel anatomical variation of CMT.

Opioid modulation of T-type Ca channel-dependent neuritogenesis/neurite outgrowth through the prostaglandin E/EP receptor/protein kinase A pathway in mouse dorsal root ganglion neurons.

Irregular regeneration or inappropriate remodeling of the axons of the primary afferent neurons after peripheral nerve trauma could be associated with the development of neuropathic pain. We analyzed the molecular mechanisms for the neuritogenesis and neurite outgrowth caused by prostaglandin E (PGE) in mouse dorsal root ganglion (DRG) neurons, and evaluated their opioid modulation. PGE in combination with IBMX, a phosphodiesterase inhibitor, caused neuritogenesis/neurite outgrowth in DRG cells, an effect abolished by a prostanoid EP, but not EP, receptor antagonist, and inhibitors of adenylyl cyclase or protein kinase A (PKA). Blockers of T-type Ca channels (T-channels), that are responsible for window currents involving the sustained low-level Ca entry at voltages near the resting membrane potentials and can be functionally upregulated by PKA, inhibited the neuritogenesis/neurite outgrowth caused by PGE/IBMX or dibutylyl cyclic AMP, a PKA activator, in DRG neurons, an inhibitory effect mimicked by ZnCl and ascorbic acid that block Ca3.2, but not Ca3.1 or Ca3.3, T-channels. Morphine and DAMGO, μ-opioid receptor (MOR) agonists, suppressed the neuritogenesis and/or neurite outgrowth induced by PGE/IBMX in DRG neurons and also DRG neuron-like ND7/23 cells, an effect reversed by naloxone or β-funaltrexamine, a selective MOR antagonist. Our data suggest that the EP receptor/PKA/Ca3.2 pathway is involved in the PGE-induced neuritogenesis/neurite outgrowth in DRG neurons, which can be suppressed by MOR stimulation. We propose that MOR agonists including morphine in the early phase after peripheral nerve trauma might delay the axonal regeneration of the primary afferent neurons but prevent the development of neuropathic pain.

Prevalence of neurological complaints among emergency department patients with severe hypertension.

Severe hypertension can accompany neurological symptoms without obvious signs of target organ damage. However, acute cerebrovascular events can also be a cause and consequence of severe hypertension. We therefore use US population-level data to determine prevalence and clinical characteristics of patients with severe hypertension and neurological complaints.

[‘s theory and clinical application of “three regions, nine needles and twelve methods”].

The paper introduces the theory and the clinical application of "three regions, nine needles and twelve methods" summarized by professor . On the basis of traditional nine needles and in association with needling technique handed down from family generations, innovated "three regions, nine needles and twelve methods". According to the treating location and anatomical structure, the needling techniques are classified in terms of three regions, i.e. the needling technique of cutaneous region, that of sinew region and that of periosteum region. Nine kinds of needle devices are developed, including two categories, i.e. miniature sinew-bone needle and grand sinew-bone needle. Based on the three-region needling techniques, 12 acupuncture methods are summarized for different areas and layers of diseases. This acupuncture technique is applicable for the treatment of chronic pain such as injury of sinews, pain in the neck, shoulder, lumbar region and leg and sequela of apoplexy.

TRPV4 is not the molecular sensor for bacterial lipopolysaccharides-induced calcium signaling.

Lipopolysaccharides (LPS) is one of the most potent pathogen-associated signals for the immune system of vertebrates. In addition to the canonical pathway of LPS detection mediated by toll-like receptor 4 (TLR4) signaling pathway, TRP channel-mediated pathways endow sensory neurons and epithelial cells with the ability to detect and react to bacterial endotoxins. Previous work revealed that LPS triggers TRPV4-dependent calcium influx in urothelial cells (UCs) and mouse tracheobronchial epithelial cells (mTEC). In marked contrast, here we show that most subtypes of LPS could not directly activate TRPV4 channel. Although LPS from Salmonella enterica serotype Minnesota evoked a [Ca] response in freshly isolated human bronchial epithelial cells (ECs), freshly isolated mouse ear skin single-cell suspensions, or HEK293T cells transiently transfected with mTRPV4, this activation occurred in a TRPV4-independent manner. Additionally, LPS from either E. coli strains or Salmonella enterica serotype Minnesota did not evoke significant difference in inflammation and pain hyperalgesia between wild type and TRPV4 deficient mice. In summary, our results demonstrate that in vitro and in vivo effects induced by LPS are independent of TRPV4, thus providing a clarity to the questioned role of LPS in TRPV4 activation.

Intracranial Hypertension and Papilledema: An Unusual Complication After the Adenoviral DNA Vector-Based Coronavirus Disease 2019 Vaccination in an Air Medical Transportation Pilot.

A 32-year-old male, Mil Mi-17 (air medical transport) helicopter pilot presented to the emergency department with a headache and visual blurring 12 days after the first dose of the Sputnik V vaccine. He had no past medical history; he successfully passed his last annual medical examination, and his vital signs were in the normal range. The significant findings were decreased visual acuity, papilledema, severe visual field narrowing, and increased nerve fiber layer thickness in both eyes. The aviation medical examiner suspended him from flight duties and referred him for a complete neuro-ophthalmic investigation. The patient underwent a lumbar puncture; his cerebrospinal fluid pressure was 39 cm HO, and his cerebrospinal fluid biochemical analysis and blood tests were normal. He refused ventriculoperitoneal shunt surgery and received methylprednisolone with acetazolamide. After 10 days, the patient reported a significant improvement. One month later, his visual acuity and visual field were better, papilledema resolved, and disc pallor appeared. Three months later, he needed no medical treatment; he had normal visual acuity and near-normal visual fields. Based on the aviation medical regulations and the importance of flight safety in air medical transportation operations, he cannot return to flight duties until full neuro-ophthalmic recovery is confirmed.
