Authors:
Sorin Tuță

Life (Basel) 2022 Jun 8;12(6). Epub 2022 Jun 8.

Department of Neurology, "Carol Davila" University of Medicine and Pharmacy, 050471 Bucharest, Romania.

In this review, we provide an update on the pathogenesis, diagnosis, and management of adults with idiopathic intracranial hypertension (IIH) and implications of the cerebral venous system, highlighting the progress made during the past decade with regard to mechanisms of the venous outflow pathway and its connection with the cerebral glymphatic and lymphatic network in genesis of IIH. Early diagnosis and treatment are crucial for favorable visual outcomes and to avoid vision loss, but there is also a risk of overdiagnosis and misdiagnosis in many patients with IIH. We also present details about treatment of intracranial hypertension, which is possible in most cases with a combination of weight loss and drug treatments, but also in selected cases with surgical interventions such as optic nerve sheath fenestration, cerebral spinal fluid (CSF) diversion, or dural venous sinus stenting for some patients with cerebral venous sinus stenosis, after careful analysis of mechanisms of intracranial hypertension, patient clinical profile, and method risks.

Non-Invasive Intracranial Pressure Monitoring and Its Applicability in Spaceflight.

Aerosp Med Hum Perform 2022 Jun;93(6):517-531

Neuro-ophthalmic findings collectively defined as Spaceflight-Associated Neuro-ocular Syndrome (SANS) are one of the leading health priorities in astronauts engaging in long duration spaceflight or prolonged microgravity exposure. Though multifactorial in etiology, similarities to terrestrial idiopathic intracranial hypertension (IIH) suggest these changes may result from an increase or impairing in intracranial pressure (ICP). Finding a portable, accessible, and reliable method of monitoring ICP is, therefore, crucial in long duration spaceflight. Read More

Papilledema and Anemia: A Rare Association.

Cureus 2022 Jun 14;14(6):e25929. Epub 2022 Jun 14.

Neurology, Gopala Gowda Shantaveri Memorial Hospital, Mysore, IND.

Papilledema is the swelling of the optic disc due to the transmission of intracranial pressure through the optic nerve. It can occur as a symptom of various intracranial pathologies that elevate the intracranial pressure. Even though anemia has been described as an association with raised intracranial pressure, the exact causal relationship between the two has not been well established in the literature. Read More

Department of Ophthalmology, College of Medicine, King Saud University, Riyadh, Saudi Arabia.

Idiopathic intracranial hypertension (IIH) is a poorly understood condition, and its presentation can coexist with other diseases. Simultaneous IIH and Duane retraction syndrome (DRS) type 1 have never been reported to coexist in an adult patient. Herein, we report a 32-year-old obese female with a history of chronic renal failure who had a renal transplant rejection 6 years prior to presentation and was treated with oral steroids and immunosuppressive medications.

Halil Onder

Ann Indian Acad Neurol 2022 Mar-Apr;25(2):214-217. Epub 2022 Jan 13.

Department of Neurology, Yozgat City Hospital, Yozgat, Turkey.

Background: Stapes reflex test is a method of evaluating the involuntary muscle contraction of the stapedius muscle in response to a high-intensity sound stimulus. The formation of this reflex involves the intact function of the 7 nerve, brain stem, 8 nerve, and middle ear. Due to ease of administration and information yielded, the stapedial reflex is considered one of the most powerful differential diagnostic audiological procedures. Read More

Single-cell RNA sequencing reveals the characteristics of cerebrospinal fluid tumour environment in breast cancer and lung cancer leptomeningeal metastases.

Clin Transl Med 2022 Jun;12(6):e885

Department of Laboratory Medicine, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.

Leptomeningeal metastases (LM) occur in patients with breast cancer (BC) and lung cancer (LC) showing exceptionally poor prognosis. The cerebrospinal fluid (CSF) tumour microenvironment (TME) of LM patients is not well defined at a single-cell level. Based on the 10× genomics single-cell RNA sequencing (scRNA-seq) data from GEO database including five patient-derived CSF samples of BC-LM and LC-LM, and four patient-derived CSF samples of idiopathic intracranial hypertension (IIH) as controls, we analysed single-cell transcriptome characteristics of CSF TME in LM patients compared to controls simultaneously and comprehensively.
