Cauda equina syndrome (CES) results from nerve root compression in the lumbosacral spine, usually due to a prolapsed intervertebral disc. Evidence for management of CES is limited by its infrequent occurrence and lack of standardised clinical definitions and outcome measures.

A 45-year-old woman presented to the emergency department of an outside hospital with shortness of breath and cough. Five days after initial presentation, the patient presented again to the same emergency department with worsening headache and progressive left arm and left leg weakness. She was transferred to the neuroscience intensive care unit of our hospital with concern for an intracranial abnormality based on her work-up at the outside hospital. Her past medical history was notable only for a large uterine fibroid. In our hospital, CT of the brain and chest (Figs 1, 2) and MRI of the brain, including perfusion studies (Figs 3, 4), were performed. Additionally, CT venography of the brain was performed (Fig 5).

Adults with chronic low back pain (CLBP) suffer impaired sleep. Medications for CLBP can impact sleep which in turn may influence treatment outcomes. This systematic review and meta-analysis examined the effects of pharmacotherapy (any type) on sleep in adults with CLBP.

During the Covid-19 pandemic, the adverse effects of recent coronaviruses on healthcare professionals cannot be ignored. This study compared the admission rates due to Covid-19 and characteristics of hospitalized healthcare workers with the general population of Kohgiluyeh and Boyer-Ahmad (K.B) province. 18546 hospitalized patients infected with Covid-19 in hospitals in four cities of K.B province were enrolled in this study; of them, 236 (1.27%) patients were healthcare workers. Demographic and clinical data of hospitalized cases due to Covid-19 infection were collected from August 2020 to September 2021. The underlying diseases were also considered in this study. According to our findings, 55.5% of the hospitalized healthcare workers were male, and 44.5% were female; their mean age was 41.41 years. However, in the general population, hospitalization rates were higher for women than for men (51.2% and 48.8%, respectively). Although the SARS-CoV-2 infectivity rate was higher in healthcare workers compared to the general population (68.6% vs. 56.1%), the mortality rate was significantly lower in them (1.7% vs. 3.8%). Fever, cough, Acute Respiratory Distress Syndrome, headache, and myalgia were the most prevalent symptoms in both groups. Among the cases examined in this study, inpatient ones aged 30-40 years and the general population aged over 60 seemed to be more likely to be hospitalized for Covid-19. The hospitalization rate of healthcare workers during the pandemic follows the same pattern as the general population, but since the start of vaccination, this rate has decreased among healthcare workers compared to the general population of KB province.

Rabbits occupy facets of veterinary medicine spanning from companion mammals, wildlife medicine, zoologic species, and research models. Therefore, analgesia is required for a variety of conditions in rabbits and is a critical component of patient care. Considerations when selecting an analgesic protocol in rabbits include timing of administration, route of administration, degree or anticipated pain, ability to access or use controlled drugs, systemic health, and any potential side effects. This review focuses on pharmacologic and locoregional management of pain in rabbits and emphasizes the need for further studies on pain management in this species.

Limited information on the analgesic efficacy and safety of even clinically commonly used analgesic drugs in guinea pigs and chinchillas is available. Buprenorphine and meloxicam are currently the most common analgesics routinely used to treat painful conditions in guinea pigs and chinchillas. Hydromorphone has also shown to be an effective analgesic drug in these species, with limited adverse effects. Tramadol in chinchillas does not provide analgesia even at high doses, and no information is available on the efficacy of this drug in guinea pigs. Multimodal analgesic protocols should be considered whenever possible.

Recent myomorph and scuiromorph rodent analgesia studies are reviewed and evaluated for potential clinical application. Differences between laboratory animal studies and clinical use in diseased animals are discussed. Analgesia classes reviewed include local anesthetics, nonsteroidal anti-inflammatories, acetaminophen, opioids, and adjuvants such as anticonvulsants. Routes of administration including sustained-release mechanisms are discussed, as are reversal agents. Drug interactions are reviewed in the context of beneficial multimodal analgesia as well as potential adverse effects. Dosage recommendations for clinical patients are explored.
