Same-visit bidirectional endoscopy (esophagogastroduodenoscopy and colonoscopy) is widely performed under sedation. At present, the optimal sedation regimen remains unclear. This study aims to test the hypothesis that a low-dose esketamine added to propofol sedation reduces hemodynamic and respiratory adverse events in these procedures.

Hypothalamic orexin (hypocretin) neurons play crucial roles in arousal control. Their involvement in anesthesia and analgesia remains to be better understood. In order to enhance our view on the neuroanatomy, we systematically mapped the projections of orexin neurons with confocal microscope and light sheet microscope. We specifically expressed optogenetic opsins tagged with fluorescence markers in orexin neurons through adeno-associated viral infection in the mouse brain. The imaging results revealed fine details and novel features of the orexin projections throughout the brain, particularly related to the nuclei regulating arousal and pain. We then optogenetically activated orexin neurons in the lateral hypothalamus to study the effects on anesthesia-related behaviors. cFos staining showed that optogenetic stimulation can activate orexin neurons in the ChR2-mCherry group, but not the control mCherry group (62.86 ± 3.923% vs. 7.9 ± 2.072%; < 0.0001). In behavior assays, optogenetic stimulation in the ChR2-mCherry group consistently elicited robust arousal from light isoflurane anesthesia (9.429 ± 3.804 s vs. 238.2 ± 17.42 s; < 0.0001), shortened the emergence time after deep isoflurane anesthesia (109.5 ± 13.59 s vs. 213.8 ± 21.77 s; = 0.0023), and increased the paw withdrawal latency in a hotplate test (11.45 ± 1.185 s vs. 8.767 ± 0.7775; = 0.0317). The structural details of orexin fibers established the neuroanatomic basis for studying the role of orexin in anesthesia and analgesia.

Spontaneous renal haemorrhage is a rare but severe condition known as Wunderlich syndrome (WS). The classic presentation includes sudden-onset flank pain, a palpable flank mass and hypovolaemic shock (Lenk's triad). WS can be due to neoplasms, vascular diseases, cystic rupture, coagulopathies and infections. A contrast-enhanced CT scan of the abdomen is mandatory for diagnosis. Surgery is reserved for haemodynamically unstable patients and those with neoplastic disease. We describe a case of WS in an anticoagulated patient with chronic atrial fibrillation, diabetes mellitus type 2 and hypertension, who developed acute renal failure and severe anaemia, that completely resolved with conservative treatment and discontinuation of anticoagulation therapy.

is a dematiaceous fungus that rarely infects the central nervous system (CNS). It is associated with a mortality rate of over 70% despite treatment.

Use of benzodiazepines and Z-drugs (non-benzodiazepine sedative hypnotics) is controversial due to adverse health outcomes in the general population. However, little is known about their use in people with multiple sclerosis (MS). We estimated the incidence and prevalence of benzodiazepine and Z-drug use (jointly BZD) in the MS population as compared to an age-, sex- and geographically-matched population without MS, and examined the association of mood/anxiety disorders with the use of BZD over a twenty-year period.

The genus () comprises 139 species including 14 species used traditionally for the treatment of various ailments such as hypertension, pain, inflammation, diabetes, cancer, microbial and mental disorders. To search research gaps through critical assessment of pharmacological activities not performed to validate traditional claims of various species of This review will aid natural product researchers in identifying species with therapeutic potential for future investigation. Scattered raw data on ethnopharmacological, morphological, phytochemical, pharmacological, toxicological, and clinical studies of various species of the genus have been compiled utilizing search engines like SciFinder, Google Scholar, PubMed, Science Direct, and Open J-Gate for 100 years up to April 2021. Few species of genus have been exhaustively investigated phytochemically, and about 129 chemical constituents related to different classes such as flavonoids, steroids, saponins, alkaloids, triterpenoids, glycosides, and phenolic compounds have been isolated from 9 species. Anticancer, antioxidant, antibacterial, CNS depressive, antidiabetic, analgesic, anti-inflammatory, and immunomodulator effects have been explored in the twelve species of the genus. A toxicity study has been conducted on 3 species and a clinical study on 2 species. The available literature on pharmacological studies of species reveals that few species have been selected based on ethnobotanical surveys for scientific validation of their traditional claims. But most of these studies have been conducted on uncharacterized and non-standardized crude extracts. A roadmap of research needs to be developed for the isolation of new bioactive compounds from species, which can emerge out as clinically potential medicines.

After surgery, the adverse effects (AEs) of analgesics are common and critical factors influencing the postoperative experience of pediatric patients. Inadequate management of AEs has been found to prolong hospital stay, increase readmission rates and decrease satisfaction with care. The aim of this qualitative descriptive study was to better understand the AEs of analgesics from the perspective of adolescent patients with idiopathic scoliosis after spinal surgery. A total of 7 patients participated in the study. Semistructured interviews were conducted at discharge and 1 week after discharge. Transcribed data were analyzed using qualitative content analysis and themes were identified. Overall, participants most frequently reported gastrointestinal and cognitive AEs, with constipation being the most persistent and bothersome. The pediatric participants used a combination of 3 strategies to mitigate analgesic AEs, namely pharmacologic, nonpharmacologic, and reduction of analgesic intake. Participants demonstrated a lack of understanding of AEs and involvement in their own care. Future studies should be conducted to evaluate the efficacy of nonpharmacological strategies in managing analgesic AEs for pediatric patients after surgery.

Elbow joint injuries are extremely common in most athletes. Athletes' chronic elbow injuries can involve multiple complex anatomical structures related to orthopedics. Therefore, it is of great significance to explore the characteristics of magnetic resonance (MR) images of chronic sports injuries of the elbow joint and the influence of acupuncture treatment on MR images and clinical symptoms.

Dissection of the superior mesenteric artery is a rare cause of abdominal pain, with a variable clinical picture. It is difficult to diagnose and there is no consensus on treatment options, which range from conservative treatment to open, endovascular, or combination repair. We describe the case of a 45-year-old man with isolated dissection of the superior mesenteric artery and persistent abdominal pain after conservative treatment had been attempted. He underwent open surgical revascularization due to the location and complexity of the dissection. Treatment consisting of endarterectomy, arterioplasty with bovine pericardium patch, and retrograde access to open the mesenteric artery with a stent was successful. Abdominal angina was completely resolved after the condition had stabilized. A combination of open and endovascular approaches should be considered as treatment for cases of isolated complex dissection of the superior mesenteric artery.

Spinal anesthesia (SPA) is the most common type of anesthesia administered for cesarean section. The main aim of this study was to evaluate the effect of aspiration of CSF (0.2 mL) immediately after SPA with hyperbaric 0.5% bupivacaine on the extent of sensory and motor block.
