Spontaneous cervical SDH with no underlying pathology is a very unusual condition. To the best of the authors' knowledge, only two cases have been previously reported. A 48-year-old female patient was admitted to our emergency room due to severe neck pain following standing up position with rapid onset of hemiparesis. MRI revealed a dorsolateral subdural hematoma from C3-C5 with cord compression. An emergency laminectomy was planned, but motor weakness gradually improved during surgical preparation. The patient showed substantial clinical improvement and complete recovery was confirmed after 7 days of conservative management without surgical treatment. To determine a differential diagnosis distinct from other conditions such as cervical epidural hematoma, a lumbar spinal puncture was performed. Follow-up MRI performed 10 days after admission revealed complete resolution of the hematoma. We report an extremely rare case of spontaneous cervical spinal subdural hematoma (SDH), present a review of relevant literature, and discuss the etiology, pathogenesis, and prognosis of this case.
Background In this study, a hydrogel comprising poly (vinyl alcohol)/pectin (PVA/PET) was prepared by the addition of Melia azedarach extract for epithelial restoration. M. azedarach extract (MAE) contains volatile organic plant-derived compounds with antimicrobial properties. MAE has a variety of physiological properties, including antimicrobial, insecticidal, and anti-inflammatory activity. This study aimed to investigate whether MAE-loaded PVA/PET hydrogels have protective effects against burn wound healing. Methods and findings To mix M. azedarach with the gel, nanoparticles containing M. azedarach were prepared using chitosan/maltodextrin as the wall material. A PVA/PET hydrogel containing M. azedarach was developed and its applicability as a wound dressing was evaluated. In the in vitro scratch assay, MAE treatment showed a scratch recovery-promoting effect comparable to that of the positive control TGF-β1. The MAE-PVA/PET hydrogel was found to be non-toxic, and the antibacterial activity of the hydrogel was excellent against both gram-positive and gram-negative bacteria. Furthermore, as the formulated hydrogel demonstrated strong antimicrobial activity, its wound-healing efficacy was investigated in vivo using a rat model. Conclusion MAE was found to be effective against burn wounds and to have antimicrobial activity in vitro and in vivo.
Rhabdomyolysis is a rare but potentially life-threatening disorder caused by the release of injured skeletal muscle components into the circulation. The authors report a case of severe head injury, in which a hyperosmolar state and continuous seizure complicated by severe rhabdomyolysis and acute renal failure evolved during the course of treatment resulted in a fatal outcome despite intensive supportive treatment. Our bitter experience suggests that rhabdomyolysis should be born in mind in patients with severe head injury who may develop hyperosmolar state and continuous seizure.
Purpose: Glehnia littoralis has been reported to have several pharmacological properties but no in vivo reports describing the protective effects of this plant on${alpha}$-amanitin-induced hepatotoxicity have been published. ${alpha}$-Amanitin is a peptide found in several mushroom species that accounts for the majority of severe mushroom poisonings leading to severe hepatonecrosis. In our previous in vitro study, we found that ${alpha}$-amanitin induced oxidative stress, which may contribute to its severe hepatotoxicity. The aim of this study was to investigate whether Glehnia littoralis acetate extract (GLEA) has protective antioxidant effects on ${alpha}$-amanitin-induced hepatotoxicity in a murine model. Methods: Swiss mice (n=40 in all groups) were divided into four groups (n=10/group). Three hours after giving ${alpha}$-amanitin (0.6 mg/kg, i.p.) to the mice, they were administered silibinin (50 mg/kg/d, i.p.) or Glehnia littoralis ethyl acetate extract (100 mg/kg/d, oral) therapies once a day for 3 days. After 72 hours of treatment, each subject was killed, cardiac blood was aspirated for hepatic aminotransferase measurement, and liver specimens were harvested to evaluate the extent of hepatonecrosis. The degree of hepatonecrosis was assessed by a pathologist blinded to the treatment group and divided into 4 categories according to the grade of hepatonecrosis. Results: GLEA significantly improved the beneficial functional parameters in ${alpha}$-amanitin-induced hepatotoxicity. In the histopathological evaluation, the toxicity that was generated with ${alpha}$-amanitin was significantly reduced by GLEA, showing a possible hepatoprotective effect. Conclusion: In this murine model, Glehnia littoralis was effective in limiting hepatic injury after ${alpha}$-amanitin poisoning. Increases of aminotransferases and degrees of hepatonecrosis were attenuated by this antidotal therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
