Background and objectives People with coronavirus disease 2019 (COVID-19) have had a wide range of symptoms reported such as fever or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, a new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting and diarrhea. The severity of disease, mortality, symptoms of COVID-19 showed significant variation in different parts of the world. The purpose of this study was to describe epidemiological characteristics and symptoms of confirmed COVID-19 patients and to identify factors associated with the severity of the disease. Methods This is a cross-sectional descriptive study conducted on hospitalized COVID-19 patients from May 2020 to July 2020. We obtained data on the demographic characteristics, symptoms, and infection severity for 150 patients by pre-tested semi-structured interview. Information was recorded in a Microsoft Excel sheet and exported to SPSS Statistics (Armonk, NY: IBM Corp.) for analysis. Results The median age of the patients was 31.5 years, where 42% of the patients were female; 52.7% of patients were symptomatic while 47.3% of patients were asymptomatic. Common symptoms at the time of admission were fever (40.5%), sore throat (36.7%), cough (32.9%), rhinitis (19.0%), and body ache (13.9%). At least one comorbidity was reported in 20.0% of the patients, with the most common comorbidity being hypertension (14.7%). History of contact with known confirmed cases of COVID-19 within the last 14 days was present in 94% of patients. The presence of any coexisting illness was significantly higher among patients with severe disease than among those with non-severe disease (80% vs. 17.9%, p=0.012). Conclusions High proportions of COVID-19 patients were asymptomatic in our study. Fever and cough were the most common symptoms. The presence of any coexisting illness was significantly higher among patients with severe disease than among those with a non-severe disease.

The purpose of this case report and literature review is to show that familial episodic pain syndrome (FEPS) is a non-inflammatory genetically inherited pain syndrome. A 3-year-old boy presented at our hospital with pain in both his forearms and lower limbs below the knees for more than 3 years. There were no abnormalities in the blood tests, blood smears, liver and kidney function tests, trace elements tests, cellular immunity test, humoral immunity test, autoantibody tests, C-reactive protein (CRP) test, erythrocyte sedimentation rate (ESR) test, and tumor-related and bone marrow cytology examinations. Additionally, the imaging examination results showed no abnormalities. From the patient's medical history, we found that the mother of the child had a family history of a similar disease. To date, only 21 cases of FEPS3 caused by the sodium voltage-gated channel alpha subunit 11A (SCN11A) gene mutation have been reported. Although the age of onset is different, most of them are inherited in families. The results of the genetic examination revealed that the pain mainly came from the genetic inheritance of the maternal family line. The whole exon gene test revealed that the pain was caused by 2 heterozygous mutations of c.674G > T and c.671T > C in the gene.

The chronic neuropathic pain of post-herpetic neuralgia (PHN) often persists for months or years after the acute herpes zoster (shingles) episode, may be severe and intractable, and can severely impact the overall quality of life. Antivirals, analgesics, and nerve blocks can effectively shorten the course of shingles and may help to prevent PHN. Although vaccination effectively prevents shingles and PHN, current therapies may be ineffective, and pain management can be challenging when PHN occurs. A 78-year-old female with severe PHN pain in the right thoracolumbar spine, right flank, and right lower abdomen showed poor responses to treatment with amitriptyline, gabapentin, and oxycodone/acetaminophen. However, a series of three thoracic transforaminal epidural steroid injections (TFESIs) effectively treated the PHN and achieved near-complete pain resolution. TFESI can be considered an early and first-choice treatment for PHN, but several courses may be required to achieve adequate and prolonged symptom control.

The aim of this study is to determine the analgesic efficacy of Transversus Abdominis Plane (TAP) block applied before anesthesia on preoperative abdominal pain and postoperative surgical pain in acute appendicitis.

Introduction Diabetic polyneuropathy (DPN) is a common chronic complication of type 2 diabetes. The pathogenesis of DPN is still debated, but proinflammatory cytokine mediators like interleukin-6 (IL-6) are possibly involved. We conducted this cross-sectional observational study to assess whether IL-6 levels increase in patients with DPN. Materials and methods This study was conducted at the Institute of Post Graduate Medical Education and Research Hospital in Kolkata, India, from 2016 to 2017. The study included 57 patients aged 30 to 60 years diagnosed with type 2 diabetes with neuropathy on clinical examination and nerve conduction study. Patients with neuropathy due to other causes were excluded. The study participants were assigned into one of four groups. Group 1 (n=15) served as healthy control patients, Group 2 (n=12) contained patients with type 2 diabetes without neuropathy, Group 3 (n=20) contained patients with type 2 diabetes with painful neuropathy, and Group 4 (n=10) contained patients with type 2 diabetes with painless neuropathy. We compared IL-6 levels between each group.  Results There was no significant difference in serum IL-6 levels between healthy controls (Group 1) and patients with type 2 diabetes without neuropathy (Group 2). However, we noted a significant increase in serum IL-6 levels among patients with painful DPN (Group 3) compared to control groups. Interestingly, serum IL-6 levels were higher in patients with painful DPN (Group 3) than patients with painless DPN (Group 4). Conclusions IL-6 increases significantly in painful diabetic neuropathy patients compared to patients with diabetes with painless neuropathy and thus may have a role in the pathogenesis of pain in DPN. Serum IL6 level can be a potential noninvasive marker of painful DPN, and it can help distinguish painful DPN from other causes of pain in patients with diabetes.

Fretting fatigue is a common problem for modular orthopedic implants which may lead to mechanical failure of the implant or inflammatory tissue responses due to excessive release of wear debris. Compressive residual stresses at the contacting surfaces may alleviate the problem. Here we investigate the potential of a surface enhancement method known as low plasticity burnishing (LPB) to increase the fretting fatigue resistance of bone-anchored implants for skeletal attachment of limb prostheses. Rotation bending fatigue tests performed on LPB treated and untreated test specimens demonstrate that the LPB treatment leads to statistically significantly increased resistance to fretting fatigue (LPB treated test specimens withstood on average 108,780 load cycles as compared with 37,845 load cycles for untreated test specimens, p = 0.004). LPB treated test specimens exhibited less wear at the modular interface as compared with untreated test specimens. This surface treatment may lead to reduced risk of fretting induced component failure and a reduced need for revision of implant system componentry.

Severe acute respiratory distress syndrome coronavirus 2 is the causative agent of COVID-19 (Coronavirus 2019) infection. Although symptoms are usually associated with the respiratory system, its neurological involvement should not be underestimated. The most common cerebrovascular complication following the infection is ischemic stroke however, CVST (Cerebral Venous Sinus Thrombosis) has been reported.

Anaesthesia and perioperative management contribute to long-term outcomes of patients with cancer, including pancreatic ductal adenocarcinoma. We assessed the antitumour, anti-inflammatory, and analgesic effects of midazolam on LSL-Kras;Trp53;Pdx-1 transgenic mice with pancreatic ductal adenocarcinoma.

The objectives of this study are to assess the efficacy and safety of peripheral nerve surgery for migraine headaches and to bibliometrically analyze all anatomical studies relevant to migraine surgery.

Chronic superficial gastritis (CSG) is a common disease of the digestive system that possesses a serious pathogenesis. Jinhong tablet (JHT), a traditional Chinese medicine (TCM) prescription, exerts therapeutic effects against CSG. However, the molecular basis of its therapeutic effect has not been clarified. Herein, we employed ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q/TOF-MS) based chemical profile identification to determine the chemical components in JHT. Further, we applied network pharmacology to illustrate its molecular mechanisms. A total of 96 chemical constituents were identified in JHT, 31 of which were confirmed using reference standards. Based on the bioinformatics analysis using the symptom-guided pharmacological networks of "chi," "blood," "pain," and "inflammation," and target screening through the interaction probabilities between compounds and targets, matrix metalloproteinase 2 (MMP2), dopamine d2 receptor (DRD2), and Aldo-keto reductase family 1 member B1 (AKR1B1) were identified as key targets in the therapeutic effect exhibited by JHT against CSG. Moreover, according to the inhibitory activities presented in the literature and binding mode analysis, the structural types of alkaloids, flavonoids, organic acids, including chlorogenic acid (), caffeic acid (), (-)-corydalmine (), (-)-isocorypalmine (), isochlorogenic acid C (), isochlorogenic acid A (), quercetin-3–α-l-rhamnoside (), isochlorogenic acid B (), quercetin (), and kaempferol () tended to show remarkable activities against CSG. Owing to the above findings, we systematically identified the chemical components of JHT and revealed its molecular mechanisms based on the symptoms associated with CSG.
