Headache is a common complaint in children who present at the pediatric emergency department (PED). Serious conditions such as intracranial tumors and idiopathic intracranial hypertension (IIH) should be rapidly ruled out. Ophthalmoscopy for the presence of papilledema has long been considered critical to the assessment of headaches in children; however, the yield of this procedure is poorly validated. This retrospective study implemented a computerized search of the medical records of a single tertiary center to identify all children aged 2-18 years who presented at the PED complaining of headache between 2007 and 2017. The clinical, demographic, radiographic, and laboratory data were analyzed. Of the 948 children aged 2-18 years who presented at the PED complaining of headache, 536 had an ophthalmoscopy examination carried out by an ophthalmologist. Forty-one had papilledema, of whom 7 had an intracranial tumor, 15 had IIH, and 9 had optic nerve head drusen. Of the 495 children without papilledema, 3 had intracranial tumor, and 11 had IIH. The sensitivity and specificity of papilledema for the diagnosis of intracranial tumor were 70% and 93.5%, respectively, with an NPV and PPV of 99.4% and 17.1%, respectively. The sensitivity and specificity of papilledema for the diagnosis of intracranial pathology in general were 61.1% and 96.2%, respectively, with an NPV and PPV of 97.2% and 53.7%, respectively.  Conclusion: Assessment by ophthalmoscopy for papilledema in children presenting to the PED with headache had high sensitivity and high specificity, thus reinforcing the importance of ophthalmoscopy as a screening tool in these children. What is Known: • Headache is a common complaint in children. Serious intracranial pathologies need to be rapidly excluded. • Ophthalmoscopy for the presence of papilledema is commonly used as a screening tool for intracranial pathology, but this procedure is poorly validated. What is New: • Ophthalmoscopy for the assessment of papilledema in children who present with headache to the pediatric emergency department is shown to exhibit sensitivity and specificity for the diagnosis of intracranial pathology.

A 44-year-old woman who was quarantined for 5 days after the diagnosis of coronavirus disease of 2019 (COVID-19) was transferred to our hospital with the complaint of chest pain. The patient was unvaccinated. Electrocardiography revealed ST elevation in the lateral leads. Echocardiographic biventricular dysfunction with oedematous wall thickening was identified. Cardiac enzyme levels were elevated; however, C-reactive protein (CRP) levels, and the coronary angiogram were normal. The patient required mechanical circulatory support to stabilize haemodynamics and was treated with remdesivir, baricitinib, and intravenous methylprednisolone. She recovered after 13 days of mechanical support. Serial cardiac magnetic resonance imaging revealed acute myocardial oedema and subsequent fibrosis. An endomyocardial biopsy on admission showed mild interstitial inflammatory infiltrates with endomyocardial fibrous thickening and mild interstitial fibrosis of the myocardium. Normal CRP levels suggested minor involvement of interleukin (IL)-6, supporting the efficacy of baricitinib.

BACKGROUND Pineal gland tumors are rare central nervous system tumors, and while neck pain and headaches may be common among those who have had these tumors removed, there is little research regarding management of these symptoms. CASE REPORT A 45-year-old man with a history of pineal germinoma treated with pinealectomy, chemotherapy, radiation therapy, and ventriculoperitoneal shunt placement at age 21 presented with chronic neck pain and headaches, which initially improved following his surgery and concurrent therapies, yet progressively worsened over the following years. He required thyroid and testosterone medication because of radiation-induced hypopituitarism, yet was employed, and until recently, active with playing tennis. He had previously seen his primary care provider, orthopedist, and neurologist, and had been cleared of severe pathology via brain magnetic resonance imaging and was referred to the chiropractor. On examination, the patient had severely limited passive cervical spine range of motion, yet hat no neurologic deficits, and radiographs showed mild cervical spondylosis and cervicothoracic scoliosis. His history and presentation were suggestive of radiation-induced fibrosis. The patient's neck pain, headaches, and quality of life improved with multimodal treatments including spinal and soft-tissue manipulation, stretches, and yoga. CONCLUSIONS This case illustrates long-term sequelae of a pineal gland tumor and its treatment, including neck pain and headache, and improvement with multimodal chiropractic therapies. Despite the success in this case, these results are not broadly generalizable. Further research is needed to understand the natural history of symptoms and effectiveness of multimodal therapies among patients who have had pineal tumor surgery.

Interferons (IFNs) are pleiotropic cytokines originally identified for their antiviral activity. IFN-α and IFN-β are both type I IFNs that have been used to treat neurological diseases such as multiple sclerosis. Microglia, astrocytes, as well as neurons in the central and peripheral nervous systems, including spinal cord neurons and dorsal root ganglion neurons, express type I IFN receptors (IFNARs). Type I IFNs play an active role in regulating cognition, aging, depression, and neurodegenerative diseases. Notably, by suppressing neuronal activity and synaptic transmission, IFN-α and IFN-β produced potent analgesia. In this article, we discuss the role of type I IFNs in cognition, neurodegenerative diseases, and pain with a focus on neuroinflammation and neuro-glial interactions and their effects on cognition, neurodegenerative diseases, and pain. The role of type I IFNs in long-haul COVID-associated neurological disorders is also discussed. Insights into type I IFN signaling in neurons and non-neuronal cells will improve our treatments of neurological disorders in various disease conditions.

Alzheimer's disease (AD), the most common cause of dementia in the elderly, is a neurodegenerative disorder associated with neurovascular dysfunction, cognitive decline, and the accumulation of amyloid β peptide (Aβ) in the brain and tau-related lesions in neurons termed neurofibrillary tangles (NFTs). Aβ deposits and NFT formation are the central pathological hallmarks in AD brains, and the majority of AD cases have been shown to exhibit a complex combination of systemic comorbidities. While AD is the foremost common cause of dementia in the elderly, age-related hearing loss (ARHL) is the most predominant sensory deficit in the elderly. During aging, chronic inflammation and resulting endothelial dysfunction have been described and might be key contributors to AD; we discuss an intriguing possible link between inner ear strial microvascular pathology and blood-brain barrier pathology and present ARHL as a potentially modifiable and treatable risk factor for AD development. We present compelling evidence that ARHL might well be seen as an important risk factor in AD development: progressive hearing impairment, leading to social isolation, and its comorbidities, such as frailty, falls, and late-onset depression, link ARHL with cognitive decline and increased risk of dementia, rendering it tempting to speculate that ARHL might be a potential common molecular and pathological trigger for AD. Additionally, one could speculate that amyloid-beta might damage the blood-labyrinth barrier as it does to the blood-brain barrier, leading to ARHL pathology. Finally, there are options for the treatment of ARHL by targeted neurotrophic factor supplementation to the cochlea to improve cognitive outcomes; they can also prevent AD development and AD-related comorbidity in the future.

Zinc finger E-box binding homeobox 1 (ZEB1) is a master modulator of the epithelial-mesenchymal transition (EMT), a process whereby epithelial cells undergo a series of molecular changes and express certain characteristics of mesenchymal cells. ZEB1, in association with other EMT transcription factors, promotes neuroinflammation through changes in the production of inflammatory mediators, the morphology and function of immune cells, and multiple signaling pathways that mediate the inflammatory response. The ZEB1-neuroinflammation axis plays a pivotal role in the pathogenesis of different CNS disorders, such as brain tumors, multiple sclerosis, cerebrovascular diseases, and neuropathic pain, by promoting tumor cell proliferation and invasiveness, formation of the hostile inflammatory micromilieu surrounding neuronal tissues, dysfunction of microglia and astrocytes, impairment of angiogenesis, and dysfunction of the blood-brain barrier. Future studies are needed to elucidate whether the ZEB1-neuroinflammation axis could serve as a diagnostic, prognostic, and/or therapeutic target for CNS disorders.

Trigeminal neuralgia is a severe facial pain disorder. Microvascular decompression is first choice surgical treatment of patients with classical TN. There exist few prospective studies with an independent evaluation of efficacy and complications after MVD.

Acute mountain sickness (AMS) is a major health issue for people travelling to high altitudes. This study was designed to comprehensively evaluate the changes in clinical characteristics and biochemical indices of high-altitude travelers and determine whether these changes were associated with AMS.

Chronic inflammatory skin disorders are known to affect sleep quality; however, the relationship between hidradenitis suppurativa (HS) and sleep is not well understood. We performed a systematic review of HS and sleep disorders and sleep quality in HS patients. We identified seven studies comprising 343,870 subjects. We found that HS patients have a higher likelihood of having a sleep disorder such as obstructive sleep apnea, as well as other non-sleep apnea. Several studies showed that patients reported worse sleep quality due to symptoms of HS such as pruritus and pain. HS patients may be at risk for additional cardiovascular comorbidities and poorer quality of life secondary to these sleep disorders and poor sleep quality. Further high-quality research evaluating these associations is warranted.

Biliary obstruction which is a major complication of pancreas and periampullary tumors could result in cholangitis, coagulopathies, gastrointestinal symptoms, and impaired wound healing. Pancreaticoduodenectomy (PD) is still the standard approach for pancreas resection and imposes high risk of morbidity and mortality to patients. To reduce the high risk of PD and address the biliary obstruction, the use of preoperative biliary stenting was increased. However, available literature doubts its efficiency.
