(RAP) has been used in Chinese traditional medicine to treat painful diseases such as rheumatism and headache. A previous study has reported that columbianadin (CBN), a major coumarin in RAP inhibits acute and inflammatory pain behaviors. However, the effects of CBN on neuropathic pain behaviors, and the potential underlying mechanism have not been reported. In the present study, the effects of CBN, compared to another major coumarin of RAP osthole (OST), on oxaliplatin-induced neuropathic pain behaviors and on the voltage-gated calcium currents in small dorsal root ganglion (DRG) neurons were studied in mice. It was found that CBN and OST inhibited both mechanical and cold hypersensitivity induced by oxaliplatin. Moreover, CBN and OST might preferentially inhibit T- and L-type calcium currents (). The inhibitory effects of CBN and OST on the oxaliplatin-induced mechanical allodynia were prevented by gabapentin. These results suggest that CBN, as well as OST might inhibit neuropathic pain behaviors through an inhibition of T- and L-type calcium currents in nociceptive DRG neurons.

Chikungunya fever (CHIKF) is an acute infectious disease that is mediated by the mosquito-transmitted chikungunya virus (CHIKV). People infected with CHIKV may experience high fever, severe joint pain, skin rash, and headache. In recent years, this disease has become a global public health problem. However, there is no licensed vaccine available for CHIKV. Accumulating research data have provided novel approaches and new directions for the development of CHIKV vaccines. Our review focuses on recent progress in CHIKV vaccine studies. The potential vaccine candidates are classified into seven types: inactivated vaccine, subunit vaccine, live-attenuated vaccine, recombinant virus-vectored vaccine, virus-like particle vaccine, chimeric vaccine, and nucleic acid vaccine. These studies will provide important insights into the future development of CHIKV vaccines.

The study was conducted to evaluate intensive care unit (ICU) patients that ultimately died but could have met criteria for end-of-life management/palliative care (ELM-PC), and to analyse the application of components of palliative care, either "unperformed procedures" or elements of "futile/unnecessary treatment".

: Persistent pain is a prevalent condition that negatively influences physical, emotional, social and family functioning in adolescents. Pain science education is a promising therapy for adults, yet to be thoroughly investigated for persistent pain in adolescents. There is a need to develop suitable curricula for adolescent pain science education. : An interdisciplinary meeting of 12 clinicians and researchers was held during March 2018 in Adelaide, South Australia. An objective of the meeting was to identify and gain consensus on key learning objectives for adolescent pain science education using a modified-Delphi process. : Consensus was reached via a modified Delphi process for seven learning objectives to form the foundation of a curriculum: 1) Pain is a protector; 2) The pain system can become overprotective; 3) Pain is a brain output; 4) Pain is not an accurate marker of tissue state; 5) There are many potential contributors to anyone's pain; 6) We are all bioplastic and; 7) Pain education is treatment. Recommendations are made for promising areas for future research in adolescent pain science education.

Long-lasting pain is a challenge for pa-tients' everyday lives. The aim of this study was to examine how women and men who have participa-ted in multimodal pain rehabilitation experience its impact in their everyday lives.

Atlantoaxial rotatory subluxation (AARS) is an uncommonly encountered diagnosis within the adult population. The rare nature of this dislocation within the adult population often results in delayed diagnosis and treatment.

Pancreatic panniculitis represents a rare dermatological manifestation mainly due to a pancreatic disorder, but other etiologies are possible. Even rarer, it can occur prior to the clinical signs of the underlying disease, and its presence must orientate the investigations especially towards pancreas, liver and neuroendocrine system. We report a rare case of a 47-year-old male patient who presented to the Emergency Unit complaining about a two weeks-long-persistent pain in the upper abdomen and biliary vomiting. The medical history included alcohol abuse. Several days prior to the onset of these symptoms, the patient has noticed the occurrence of a nodular inflammatory lesion of 5∕3 cm on the right calf (this makes the case even rarer). Based on clinical aspect and high levels of pancreatic enzymes, acute pancreatitis was diagnosed. Contrast-enhanced abdominal computed tomography (CT) revealed a cystic pancreatic mass and dilated intrahepatic biliary ducts. Abdominal magnetic resonance imaging (MRI) revealed a cystic tumor of the pancreatic head and thrombosis of the portal vein, which increased the suspicion of pancreatic adenocarcinoma. Biopsy was performed from the calf nodular lesion, with the diagnosis of panniculitis. This case, besides its rarity, supports the clinical important value of a pancreatic workup in case of histologically proved panniculitis, even without pancreatic related symptoms.

Most vulvodynia patients receive combinations of several treatment modalities for their chronic painful condition. If conservative treatments fail, vestibulectomy is considered to be the ultimate treatment option for localized provoked vulvodynia (LPV). The aim of this descriptive study was to analyze relief of pain, quality of life (QoL), and complications associated with combining surgery with conservative treatments among LPV patients, both in short term and after 3 years of follow-up. The study population consisted of a retrospective patient cohort of surgically ( = 16) and only conservatively ( = 50) treated LPV patients. QoL data were assessed by a validated questionnaire (RAND-36). Data were collected by reviewing patient records and by aid of postal questionnaires. Efficacy of treatments in relief of pain was measured by numerical rating scale (NRS). Two months after surgery, the NRS scores assessed by a physician were lower in the surgery group than in patients treated only conservatively ( = 0.008). However, after a median of 36 months of follow-up, self-reported NRS scores and QoL showed no difference between the two patient cohorts. Complication rate after vestibulectomy was 18.8%. The findings suggest that combining surgery with conservative treatments may result in a more effective short-term reduction of pain. However, the effect seemed to be only temporary, as no long-term benefit was achieved.

Hereditary fructose intolerance, caused by mutations in the ALDOB gene, is an unusual cause of hypoglycemia. ALDOB encodes the enzyme aldolase B, responsible for the hydrolysis of fructose 1-phosphate in the liver. Here, we report the case of a 33-year-old female patient who consulted due to repetitive episodes of weakness, dizziness and headache after food ingestion. An ambulatory 72-h continuous glucose monitoring revealed multiple short hypoglycemic episodes over the day. After biochemical exclusion of other endocrine causes of hypoglycemia, hereditary fructose intolerance seemed a plausible diagnosis. Repeated measurements of urinary fructose revealed pathologic fructosuria, but genetic testing for the three most common mutations in ALDOB resulted negative. We decided to perform complete Sanger sequencing of the ALDOB gene and encountered a variant consisting of a T>A substitution in position 1963 of the ALDOB transcript (c.1693T>A). This position is located within the 3' untranslated region of exon 9, 515 nucleotides downstream the stop codon. After complete withdrawal of dietary fructose and sucrose, the patient presented no new hypoglycemic episodes.

Patients after total knee arthroplasty (TKA) often develop moderate to severe pain. This study compared the analgesic effect of low-dose epidural morphine vs. a comparable saline injection in patients following TKA surgery.
