Contrast-enhanced paravertebrogram to confirm paravertebral catheter position in elective thoracic surgery: a proof of concept study.

Paravertebral pain catheters have been shown to be equally effective as epidural pain catheters for postoperative analgesia after thoracic surgery with the possible additional benefit of less hemodynamic effect. However, a methodology for verifying correct paravertebral catheter placement has not been tested or objectively confirmed in previous studies. The aim of the current study was to describe a technique to confirm the correct position of a paravertebral pain catheter using a contrast-enhanced paravertebrogram.

Exuberant fibroblast activity compromises lung function via ADAMTS4.

Severe respiratory infections can result in acute respiratory distress syndrome (ARDS). There are no effective pharmacological therapies that have been shown to improve outcomes for patients with ARDS. Although th influenza A/Puerto Rico/8/34 e host inflammatory response limits spread of and eventually clears the pathogen, immunopathology is a major contributor to tissue damage and ARDS. Here we demonstrate that respiratory viral infection induces distinct fibroblast activation states, which we term extracellular matrix (ECM)-synthesizing, damage-responsive and interferon-responsive states. We provide evidence that excess activity of damage-responsive lung fibroblasts drives lethal immunopathology during severe influenza virus infection. By producing ECM-remodelling enzymes-in particular the ECM protease ADAMTS4-and inflammatory cytokines, damage-responsive fibroblasts modify the lung microenvironment to promote robust immune cell infiltration at the expense of lung function. In three cohorts of human participants, the levels of ADAMTS4 in the lower respiratory tract were associated with the severity of infection with seasonal or avian influenza virus. A therapeutic agent that targets the ECM protease activity of damage-responsive lung fibroblasts could provide a promising approach to preserving lung function and improving clinical outcomes following severe respiratory infections.

Non-surgical management of knee osteoarthritis: comparison of ESCEO and OARSI 2019 guidelines.

Knee osteoarthritis (OA) is a heterogeneous disease associated with substantial effects on quality of life, and its clinical management is difficult. Among the several available guidelines for the management of knee OA, those from OARSI and ESCEO were updated in 2019. Here, we examine the similarities and differences between these two guidelines and provide a narrative to help guide health-care providers through the complexities of non-surgical management of knee OA. OARSI and ESCEO both recommend education, structured exercise and weight loss as core treatments, topical NSAIDs as first-line treatments and oral NSAIDs and intra-articular injections for persistent pain. Low-dose, short-term acetaminophen, pharmaceutical grade glucosamine and chondroitin sulfate are recommended by ESCEO whereas OARSI strongly recommends against their use (including all glucosamine and chondroitin formulations). Despite this difference, the two guidelines are consistent in the majority of their recommendations and provide useful treatment recommendations for individuals with OA and health-care providers.

Cannabinoid hyperemesis syndrome: definition, pathophysiology, clinical spectrum, insights into acute and long-term management.

Although cannabinoid hyperemesis syndrome (CHS) was first reported more than 15 years ago, it still remains an unfamiliar clinical entity among physicians worldwide. CHS is categorized by Rome IV classification as a functional gastroduodenal disorder. It is characterized by stereotypical episodic vomiting in the setting of chronic, daily cannabis use, with cycles decreasing by the cessation of cannabis. CHS is also associated with abdominal pain reduced by hot baths and showers with comparative well-being between attacks. Thus, its clinical presentation resembles 'classic' cyclic vomiting syndrome, but eliciting a cannabis history is crucial in diagnosing this entity. In acute attacks, parenteral benzodiazepines are very effective. For prevention and long-term management, tricyclic antidepressants such as amitriptyline are the mainstay of therapy requiring doses in the range of 50-200 mg/d to achieve symptom control. In addition, counseling to achieve marijuana cessation, accompanied by antianxiety medications, is necessary for sustaining clinical outcomes. Once the patient is in remission and off marijuana for a period of 6-12 months, then tapering the dose of amitriptyline can be implemented, with the goal of no therapy being achieved in the majority of patients over time. With the legalization of marijuana in many states, CHS will become an increasingly prevalent clinical entity, so educating about CHS is an important goal, particularly for emergency department physicians who generally first encounter these patients.

Pragmatic approach to neuraxial anesthesia in obstetric patients with disorders of the vertebral column, spinal cord and neuromuscular system.

Neuraxial anesthesia provides optimal labor analgesia and cesarean delivery anesthesia. Obstetric patients with disorders of the vertebral column, spinal cord and neuromuscular system present unique challenges to the anesthesiologist. Potential concerns include mechanical interference, patient injury and the need for imaging. Unfortunately, the existing literature regarding neuraxial anesthesia in these patients is largely limited to case series and rare retrospective studies. The lack of practice guidance may lead to unwarranted fear of patient harm and subsequent avoidance of neuraxial anesthesia for cesarean delivery or neuraxial analgesia for labor, with additional risks of exposure to general anesthesia. In this narrative review, we use available evidence to recommend a framework when considering neuraxial anesthesia for an obstetrical patient with neuraxial pathology.

Genital herpes – diagnosis, treatments, attitudes and response to disclosure amongst members of the UK Herpes Viruses Association.

A diagnosis of genital herpes may result in psychological as well as physical morbidity. Many patients require on-going help and contact the Herpes Viruses Association (HVA), a UK patient support organisation. The HVA conducts occasional questionnaires relating to various issues surrounding herpes and this study reports on a survey conducted amongst members in 2015. The survey was done using SurveyMonkey and covered diagnosis/treatment, both allopathic and self-help, physical and psychological impact and disclosure to partners. Three hundred and fifty-eight women and 103 men completed the questionnaire. Male respondents were older than women (48.6 versus 42.9 years). The majority were first diagnosed in sexual health clinics. A high proportion had informed partners about the diagnosis and in 83% disclosure did not result in rejection. 57% were taking prophylaxis with more taking treatment episodically rather than continually; 11.3% sourced medications on-line. Alternative treatments were used commonly with Lomaherpan cream (, lidocaine ointment and a diet with reduced arginine and increased lysine the most frequent choices. Other alternative treatments included olive leaf extract, and vitamin supplements. Women reported being troubled psychologically more than men. Neuropathic pain was reported by 80.4% of the women and 64.1% of the men. Although antiviral treatment is cheap and well-tolerated it is still being refused by some healthcare providers. There still appears to be a considerable degree of stigma experienced by patients which can be mitigated by support from patients' support groups such as the HVA.

Modeling and visualizing two-way contingency tables using compositional data analysis: A case-study on individual self-prediction of migraine days.

Two-way contingency tables arise in many fields, such as in medical studies, where the relation between two discrete random variables or responses is to be assessed. We propose to analyze and visualize a sample of 2 × 2 tables in the context of single-subject repeated measurements design by means of compositional data (CoDa) methods. First, we propose to visualize the tables in a quaternary diagram. Second, we show how to represent these tables by means of logratios indicating the relationship between the two variables as well as their strength and direction of dependency. Finally, we describe a technique to model those tables with a simplicial regression model. Data from a real-world study of self-prediction of migraine attack onset is used to illustrate this methodology. For each individual, the 2 × 2 table of their migraine expectation vs next day migraine occurrence is computed, generating a sample of tables. Then we visualize and interpret the prediction ability of individuals both in the simplex and in terms of logratios of components. Finally, we model the self-prediction ability with respect to demographic variables, days tracked and disease characteristics. Our application demonstrates that CoDa can be a useful tool for visualizing, modeling, and interpreting the components of 2 × 2 tables.
