Capsaicin-containing (CP) pharmacopuncture was developed to treat neuropathic pain. This study was conducted to assess the toxicity of CP extract for pharmacopuncture, using a micronucleus test.

Approximately 20% of North Americans are afflicted with chronic pain with 3% being opioid users. The objective was to determine whether patients on opioids for chronic pain with newly diagnosed sleep apnea attended sleep clinic review and followed treatment recommendations.

West Nile fever (WNF) is a vector-borne infection caused by a Flavivirus-West Nile virus (WNV). WNV is transmitted by mosquitoes, and birds are the major natural reservoir. A recent increase in the number of the WNF cases has been reported in Europe, the Balkans, and Bulgaria. We herein present the clinical course, laboratory and imaging findings of three patients – a female and two male patients, who were diagnosed with WNF. They were investigated in an epidemiological study, and by using clinical observation, laboratory and microbiological methods, serological tests for specific anti-WNV antibodies detection, molecular biology techniques (polymerase chain reaction, PCR), computed tomography (CT) and magnetic resonance imaging (MRI). The patients presented with fever, headache, drowsiness, and dizziness and anti-WNV antibodies were detected in their serum samples. WNV-RNA was found in a blood sample from the female patient. Both anti-WNV IgM and Herpes simplex virus-1 DNA were detected in a cerebrospinal fluid sample from one of the men. The three patients recovered from the disease after a long convalescent period. WNF has no specific signs, laboratory and imaging findings and could be a life-threatening condition, leading to serious complications. Therefore, WNF should be taken into consideration during the summer when the vector of the infection is active.

In October 2015, 65 people came into direct contact with a healthcare worker presenting with a late reactivation of Ebola virus disease (EVD) in the UK. Vaccination was offered to 45 individuals with an initial assessment of high exposure risk.

Perianal and perineal pruritus is often associated with Enterobius vermicularis in children. Although this roundworm is common in pediatric practice, most doctors are unaware that it can cause appendicular colic with/or appendicitis, severe urogenital complications, bowel perforation, and peritonitis. We report a case of a young male who presented with signs and symptoms of acute peritonitis. Dur-ing the operation, perforation of the jejunum with a purulent exudate under the transverse colon, a left lateral canal, a Douglas cavity were found as well as single enlarged mesenteric lymph nodes. Histological studies detected Enterobius vermicularis in the lumen of the appendix and jejunum, as well as in the purulent exudate in the intestinal wall and serosa. A mesenteric lymph node, histologically presented with chronic nonspecific lymphadenitis. In conclusion, infection with Enterobius vermicularis should be considered in peri-tonitis, appendicitis, and enlarged mesenteric lymph nodes, especially in young patients.

There are no reliable prospective studies on the effectiveness of topiramate in Bulgarian adult patients with drug-resistant epilepsy.

Insomnia is a chronic condition that occurs a minimum of three times per week over a period of three or more subsequent months. There are multiple causes of insomnia, and even though it is considered a symptom, it can be associated with chronic illnesses. Chronic pain syndrome, which is defined as pain that persists for a period longer than 3 months, is one of several etiologies of insomnia. The prevalence of insomnia among chronic pain patients is greater in comparison with the general population (percentage or ratio). Chronic pain is common in patients with rheumatoid arthritis, spinal pain (such as chronic back pain) and fibromyalgia. The prevalence of in-somnia is also higher in cancer patients when compared to the general population. When the clinical history indicates a straightforward diagnosis of chronic pain syndrome, patients will complain of insomnia as part of their symptomatology. It is imperative to manage their underlying illness to alleviate their sleep disorder. Various medications may be used to relieve and even improve pain symptoms. Other than pharmacological interventions, non-pharmacological alternatives such as yoga, meditation, acupuncture, and psychotherapy can help improve the quality of life of these patients. The purpose of this article is to review the diagnosis and management of insomnia in chronic pain syndrome and its impact on the quality of life.

Objective To investigate the feature and frequency of medical emergencies in dental clinics in China and the associated factors for Chinese dentists experiencing medical emergencies.Methods A survey study was conducted among 2408 dentists who attended continuing educational courses held by Society of Sedation and Analgesia of Chinese Stomatological Association in 18 cities from December 2015 to December 2018. Demographic information of the dentists and the characteristics of medical emergencies they encountered were collected and analyzed. The associated demographic features for dentist experiencing medical emergencies were analyzed by logistic regression model.Results A total of 2013 dentists provided valid responses and reported 2923 events of medical emergencies in dental clinics. Among them, 85.0% reported that they had encountered medical emergencies, and 35.5% had encountered at least twice. Syncope (35.9%) and hypoglycemia (30.3%) were the most common reported medical emergencies. Medical emergencies were most likely to occur during local anesthesia (49.9%), out-patient oral surgery (25.9%), and root canal treatment (11.3%). There were 6 patients (0.2%) died in emergencies. 84.0% dentists reported that they had never received training courses about medical emergency management in dentistry other than Basic Life Support. Longer practicing time (10-15 years) (=0.59, 95% : 0.41-0.85, =0.004), working in private dental facilities (=1.69, 95% : 1.20-2.38, =0.003) were associated with an increased risk of experiencing medical emergencies.Conclusion More efforts are needed in prevention, early identification, and timely management of medical emergencies in dental clinics in order to prevent fatal outcomes. The results of this survey are useful information for re-designing emergency training courses for Chinese dentists.

Objectives Transmuscular quadratus lumborum block (TQLB) may provide postoperative analgesia in patients undergoing intraperitoneal surgeries. The purpose of this study was to examine the potential efficacy of TQLB among patients undergoing retroperitoneal procedures, such as the laparoscopic partial nephrectomy (LPN). Methods This prospective, randomized, controlled study was conducted from August 2017 to November 2018 at Peking Union Medical College Hospital (Beijing, China). Patients who were scheduled for a LPN, aged 18-70 years old with an ASA physical status score of I – II were randomly assigned to receive either TQLB with 0.6 ml/kg of 0.5% ropivacaine plus general anesthesia (TQLB group) or general anesthesia alone (control group). Patient-controlled intravenous analgesia with morphine was initiated immediately upon surgery completion. The primary outcome was the cumulative consumption of morphine within 8 h after surgery. The secondary outcome included postoperative consumptions of morphine at other time points, pain score at rest and during activity, postoperative nausea and vomitting (PONV), and recovery related parameters. Results Totally 30 patients per group were recruited in the study. The 8 h consumption of morphine was lower in the TQLB group than in the control group (median, 0.023 mg/kg . 0.068 mg/kg, U=207.5, <0.001). No significant differences were observed in postoperative pain scores between the two groups. Patients in the TQLB group had fewer episodes of PONV (20% 47%, =4.8, =0.028) in the first 24 h after surgery and higher scores for quality of recovery (mean, 138.6 131.9, =-2.164, =0.035) 120 h after surgery than the controls. Conclusions TQLB resulted in an opioid-sparing effect during the early postoperative period following LPN, as well as a lower incidence of PONV and improved quality of recovery.
