Multimodal analgesia (MMA) may reduce opioid use after surgery for Chiari malformation type I. An MMA protocol was implemented after both posterior fossa decompression without dural opening (PFD) and posterior fossa decompression with duraplasty (PFDD).

In the absence of baseline testing, normative data may be used to interpret postconcussion scores on the clinical reaction-time test (RT). However, to provide normative data, we must understand the performance factors associated with baseline testing.

The search for an effective medication that will eliminate tinnitus has a long history. Currently, no drugs exist that universally cure tinnitus. Pharmacologic interventions that have been investigated can be divided into those that attempt to eliminate the perception of tinnitus, and those that are designed to treat the negative comorbidities associated with tinnitus, thereby mitigating tinnitus' negative impact on quality of life. A third category of drugs can also be considered that addresses an identified pathologic condition that has tinnitus as an associated symptom (for example, Meniere's disease, otosclerosis, migraine-associated vertigo). This third category is not addressed.

Osteoporosis presents a major threat to the health of women older than 65 years. Bisphosphonates (BPs) are now the principal class of medications for osteoporosis.

Methadone is a useful option in the treatment of cancer pain. Despite its advantages, methadone use is complicated due to high interindividual variability in pharmacokinetics. Various rotation methods from other opioids have been proposed in mostly Caucasian populations.

A new pathogenic virus, COVID-19, appeared in 2019, in Wuhan, China, typically causing fever, cough, diarrhea and fatigue and significant mortality (Mao, 2020). From mid-January to mid-February in 2020, 214 patients with both non-severe and severe COVID-19 infections confirmed by nucleic acid tests, were examined by a panel of neurologists. Seventy-eight patients (36.4%) displayed neurological symptoms, including central nervous system symptoms of dizziness, headache, impaired consciousness, acute cerebrovascular disease with either ischemic stroke or cerebral hemorrhage, ataxia, seizures; peripheral nervous system symptoms of taste impairment, smell impairment, vision impairment, and nerve pain; and skeletal muscle injury (Mao, 2020).

Patients with cerebral venous thrombosis (CVT) often present with slowly progressive symptoms, leading to delay in diagnosis. The aim of our single-center study was to highlight the clinical patterns and etiological features of CVT, and to show the impact of diagnostic delay on prognosis in Algerian adults.

The concept that disease rooted principally in chronic aberrant constitutive and reactive activation of mast cells (MCs), without the gross MC neoplasia in mastocytosis, first emerged in the 1980s, but only in the last decade has recognition of "mast cell activation syndrome" (MCAS) grown significantly. Two principal proposals for diagnostic criteria have emerged. One, originally published in 2012, is labeled by its authors as a "consensus" (re-termed here as "consensus-1"). Another sizable contingent of investigators and practitioners favor a different approach (originally published in 2011, newly termed here as "consensus-2"), resembling "consensus-1" in some respects but differing in others, leading to substantial differences between these proposals in the numbers of patients qualifying for diagnosis (and thus treatment). Overdiagnosis by "consensus-2" criteria has potential to be problematic, but underdiagnosis by "consensus-1" criteria seems the far larger problem given (1) increasing appreciation that MCAS is prevalent (up to 17% of the general population), and (2) most MCAS patients, regardless of illness duration prior to diagnosis, can eventually identify treatment yielding sustained improvement. We analyze these proposals (and others) and suggest that, until careful research provides more definitive answers, diagnosis by either proposal is valid, reasonable, and helpful.

An outbreak of a novel coronavirus (SARS-CoV-2) infection has recently emerged and rapidly spreading in humans causing a significant threat to international health and the economy. Rapid assessment and warning are crucial for an outbreak analysis in response to serious public health. SARS-CoV-2 shares highly homological sequences with SARS-CoVs causing highly lethal pneumonia with respiratory distress and clinical symptoms similar to those reported for SARS-CoV and MERS-CoV infections. Notably, some COVID-19 patients also expressed neurologic signs like nausea, headache, and vomiting. Several studies have reported that coronaviruses are not only causing respiratory illness but also invade the central nervous system through a synapse-connected route. SARS-CoV infections are reported in both patients and experimental animals' brains. Interestingly, some COVID-19 patients have shown the presence of SARS-CoV-2 virus in their cerebrospinal fluid. Considering the similarities between SARS-CoV and SARS-CoV-2 in various aspects, it remains to clarify whether the potent invasion of SARS-CoV-2 may affect in COVID-19 patients. All these indicate that more detailed criteria are needed for the treatment and the prevention of SARS-CoV-2 infected patients. In the absence of potential interventions for COVID-19, there is an urgent need for an alternative strategy to control the spread of this disease. This article is protected by copyright.
