After a scorpion sting, patients commonly present to hospitals with pain. Our study sought to compare the analgesic efficacy of IV paracetamol, IV dexketoprofen trometamol, topical lidocaine, and placebo in patients reporting pain after presenting with a history of scorpion sting.

The condition of PPPD is a common chronic vestibular disorder that is thought to be due to a central vestibular maladaptation. The condition is frequently encountered in those with a history of migraine, anxiety or panic attacks. Many cases of PPPD are preceded by vestibular disorders with vestibular migraine thought to precede at least 20% of cases.1 Those with a history of migraine have been shown to have difficulties with sensory integration, habituation and intolerance to stimuli. This often leads to discomfort associated with some vestibular test procedures. We pose a case report of a patient with a history of migraine that developed new onset PPPD following caloric irrigations.

Symptomatic arsenic toxicity has not been associated with terracotta pottery despite thousands of years of use in food storage and preparation. We describe a case of chronic arsenic toxicity from undiagnosed pica involving the ingestion of terracotta pots.

Gabapentinoids are specific ligands for the αδ-1 subunit of voltage-gated calcium channels. This class of drugs, including gabapentin and pregabalin, exert various pharmacological effects and are widely used for the treatment of epilepsy, anxiety, and chronic pain. The mechanism of action of gabapentinoids involves both direct modulation of calcium channel kinetics and inhibition of channel trafficking and expression, which contribute to the above pharmacological effects. In the present study, we investigated the effects of mirogabalin, a novel potent gabapentinoid, on expression levels of the αδ-1 subunit in the spinal dorsal horn in a rat model of spinal nerve ligation (SNL) as an experimental animal model for peripheral neuropathic pain. The neuropathic pain state was induced by SNL in male Sprague – Dawley rats. After the development of mechanical hypersensitivity, the animals received 10 mg/kg mirogabalin or vehicle orally for 5 consecutive days and were subjected to immunohistochemical analysis of αδ-1 subunit expression in the spinal cord. In the SNL model rats, expression of the αδ-1 subunit significantly increased in the spinal dorsal horn at the ipsilateral side of nerve injury, while mirogabalin inhibited this increase. In conclusion, the αδ-1 subunit was upregulated in the spinal dorsal horn of SNL model rats, and repeated administration of mirogabalin inhibited this upregulation. The inhibitory effect of mirogabalin on upregulation of the αδ-1 subunit after nerve injury is considered to contribute to its analgesic effects in peripheral neuropathic pain.

This video demonstrates the microsurgical resection of petrous apex meningioma. Even small lesions by general rules are regarded as large due to delicate nature of anatomical localization. The intricate relationship between the tumor and vascular supply of the brainstem and interposition of cranial nerves makes them challenging lesions to resect..

Recently, inflammation and free-radical release has been described in the surrounding brain parenchyma of seemingly inert calcified lesions of neurocysticercosis. These free radicals can induce migraine by stimulating calcitonin gene-related peptide release. This stipulated mechanism led us to hypothesize that calcified neurocysticercosis may increase migraine severity. This case-control study included patients (migraine with calcified neurocysticercosis) and control subjects (migraine without calcified neurocysticercosis) in a 1:1 ratio. Headache frequency, visual analog scale (VAS) score, and Migraine Disability Assessment (MIDAS) score were assessed at baseline and at the end of 3 months. To compare treatment responsiveness between patients and control subjects, we treated both groups identically so that difference in treatment would not confound the results. Each group comprised 78 patients. Baseline headache frequency (11.3 ± 3.3 versus 7.9 ± 3.4), VAS score (7.5 ± 1.1 versus 6.0 ± 1.2), and MIDAS score (15 ± 7.6 versus 9.6 ± 4.5) were significantly greater in patients than control subjects. Interestingly, the change from baseline to the end of 3 months in headache frequency (6.0 ± 1.7 versus 2.8 ± 1.4), VAS score (2.6 ± 0.02 versus 1.4 ± 0.01), and MIDAS score (8.3 ± 5.0 versus 3.6 ± 2.0) were significantly greater in patients than control subjects. Our study emphasizes that calcified lesions of neurocysticercosis are not inert, and cause an increase in the frequency and severity of migraine attacks. Interestingly, these patients also showed a better response to treatment with amitriptyline, possibly resulting from its anti-inflammatory action. Further studies are warranted to explore possible inflammatory mechanisms in calcified neurocysticercosis, which influences migraine physiology.

Preparations from the bark and leaves of Schinus terebinthifolia Raddi are commonly used to treat toothaches and sore throats. The use of medications based on leaves of this plant has also been reported for pain of arthritis, toothache, and sore throat. Some evidence indicated that the lectin SteLL is an antinociceptive agent from leaves.

We evaluated the perioperative analgesic effects of the inter-semispinal plane (ISP) block in patients undergoing posterior cervical spine surgery.

Determine factors associated with Irritable bowel syndrome (IBS) in nonalcoholic fatty liver disease (NAFLD) patients.

The clinical and hematological parameters of children with dengue during an outbreak in a non-endemic region have not been well described. To delineate the clinical profile of pediatric cases from a tertiary care center located in a non-endemic zone (Tangail district) in Bangladesh was the objective of the study.
