Rothia prosthetic knee joint infection

Rothia species — Gram-positive pleomorphic bacteria that are part of the normal oral and respiratory flora — are commonly associated with dental cavities and periodontal disease although systemic infections have been described. We describe a 53-year-old female with rheumatoid arthritis complicated by prosthetic knee joint infection due to Rothia species, which was successfully treated by surgical removal of prosthesis and prolonged antimicrobial therapy. The issue of antibiotic prophylaxis before dental procedures among patients with prosthetic joint replacements is discussed

Comparison of efficacy and safety of thiocolchicoside and pregabalin in the treatment of acute non-specific low back pain: an open label randomized prospective study

Background: The present study was undertaken to study the efficacy and safety of thiocolchicoside, a centrally acting skeletal muscle relaxant, GABA mimetic drug and pregabalin, an anti-epileptic, GABA mimetic drug in the treatment of acute non-specific low back pain.Methods: The study was carried out at the orthopaedic outpatient department of our hospital. 80 patients were included during the study period of two months. Out of the 80, 40 were given pregabalin 75 mg 1hs and the rest were given thiocolchicoside 8 mg bd by the prescribing doctor. Patients, aged between 18-60 years having non-radiating low back pain for less than 7 days were selected. The data was collected in a proforma which included the patient’s details and the prescribed drugs. The patients were also given notepads to record adverse effects. On day 1, the pain was measured on visual analogue scale. After a week, follow up was done and decrease in pain was measured on the visual analogue scale.Results: There was significant difference between pre and post visual analogue scale score in both the groups with a p-value of less than 0.0001. But the difference between the two groups was not statistically significant (p-value 0.0664). In both the groups, patients did not report any adverse effects. Pregabalin has a slower onset than thiocolchicoside however has better efficacy. In India, where the drug abuse risk is higher, pregabalin is a safer choice as skeletal muscle relaxants (thiocolchicoside) should not be given for more than a week.Conclusions: Pregabalin has better efficacy in treatment of acute non-specific low back pain as compared to thiocolchicoside

Impact of climate change on medicinal and aromatic plants: Review

There has been worldwide changes in seasonal patterns, weather events, temperature ranges, and other related phenomena and all have been analyzed in partial, reported and attributed to global climate change. The negative impacts of climate change will become much more intense and frequent in the future—particularly if environmentally destructive human activities continue unabated, warned categorically by a number of experts in a wide range of scientific disciplines and interests. Medicinal and aromatic plants (MAPs) are not immune to the effects of climate change like all other living members of the biosphere. Clear signals are coming on climate change impact which is causing noticeable effects on the lifecycles and distributions of the world’s vegetation, including wild MAPs across the world. This in turn causing some MAPs endemic to geographic regions or ecosystems which could put them at risk and are particularly vulnerable to climate change. Such serious issues and challenges are a continuous concern with regard to the survival and genetic integrity of some MAPs and are being discussed within various forum and platform. Further, such issues of climate change will definitely pose a more prominent or immediate threat to MAP species than other threats, however, scientists do not know whether climate change has the potential to exert increasing pressures  upon MAP species and populations. Climate change impact may have a tremendous possible effect on MAPs particularly significant due to their value within traditional systems of medicine and as economically useful plants. At this stage, the future effects of climate change are largely uncertain more so with MAPs, but current evidence suggests that these phenomena are having an impact on MAPs and that there are some potential threats worthy of concern and discussion

Preoperative characterization of indeterminate large adrenal masses with dual tracer PET-CT using fluorine-18 fluorodeoxyglucose and gallium-68-DOTANOC: initial results

PURPOSEWe aimed to evaluate the usefulness of dual tracer positron emission tomography-computed tomography (PET-CT) with flourine-18 fluorodeoxyglucose (18F-FDG) and gallium-68 [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI3-octreotide (68Ga-DOTANOC) in preoperative characterization of large indeterminate adrenal masses.MATERIALS AND METHODSTen patients (four males, six females; median age, 35 years) with indeterminate, large (≥4 cm) adrenal masses were included in this prospective study. All patients underwent both 18F-FDG PET-CT and 68Ga-DOTANOC PET-CT within one week. Images were evaluated both visually and semi-quantitatively, with standardized uptake value (SUVmax) and SUVratio (SUVmax) of tumor/SUVmax) of mediastinum). Based on differential uptake pattern on 18F-FDG and 68Ga-DOTANOC, lesions were classified as cortical (18F-FDG>68Ga-DOTANOC), medullary (68Ga-DOTANOC>18F-FDG), or indeterminate (18F-FDG=68Ga-DOTANOC). Histopathology was taken as reference standard. Receiver operating characteristic (ROC) analysis was performed to find a cut-off of SUVmax) and SUVratio to differentiate cortical and medullary lesions.RESULTSOn histopathology, eight lesions were adrenocortical carcinomas, one was benign pheochromocytoma, and one was malignant pheochromocytoma. Visually, 18F-FDG PET-CT was positive in all ten lesions, while 68Ga-DOTANOC PET-CT was positive in two, both of which were pheochromocytomas. On SUVmax) based analysis, nine lesions were cortical and one was medullary. On ROC analysis, a SUVmax) cut-off of > 2.3 was obtained for 18F-FDG PET-CT and 3.6 for 68Ga-DOTANOC PET-CT for differentiating adrenal cortical and medullary lesions. The cut-off for SUVratio was 4.5 on 18F-FDG PET-CT and 11.1 on 68Ga-DOTANOC PET-CT.CONCLUSIONThese preliminary results demonstrate that dual tracer PET-CT using 18F-FDG and 68Ga-DOTANOC could be informative in the preoperative characterization of large indeterminate adrenal masses

Evaluation of Gamma glutamyl-transferase (GGT) levels in COVID-19: A retrospective analysis in tertiary care centre

Many recent studies have reported that patients infected with novel coronavirus 2019 or SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) might have a liver injury. However, few studies have focussed on the levels of Gamma glutamyl-transferase (GGT) alone and the variations associated with it. We retrospectively analysed the GGT levels of 476 admitted patients with confirmed COVID-19 in a tertiary care centre, PGIMER (Post Graduate Institute of Medical Education and Research), Chandigarh. Out of the total 476 COVID-19 patients studied, 35% had elevated GGT levels. ICU care was required for 51.19% (P <0.0001) of these patients and their hospital stay was of longer duration as compared to the patients with normal GGT levels. The incidence of GGT elevation was found to be more pronounced in males and elderly patients. The male population displayed higher GGT levels with 52% having raised levels compared to females where only 21.6% had elevated GGT levels. Although the number of COVID-19 cases was majorly from young age groups, the elevation in GGT levels has been reported more in elderly patients. GGT levels can therefore serve as a predictor for the extent of liver injury and severity in COVID-19 patients

The COVID-19 Data Portal: accelerating SARS-CoV-2 and COVID-19 research through rapid open access data sharing.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic will be remembered as one of the defining events of the 21st century. The rapid global outbreak has had significant impacts on human society and is already responsible for millions of deaths. Understanding and tackling the impact of the virus has required a worldwide mobilisation and coordination of scientific research. The COVID-19 Data Portal (https://www.covid19dataportal.org/) was first released as part of the European COVID-19 Data Platform, on April 20th 2020 to facilitate rapid and open data sharing and analysis, to accelerate global SARS-CoV-2 and COVID-19 research. The COVID-19 Data Portal has fortnightly feature releases to continue to add new data types, search options, visualisations and improvements based on user feedback and research. The open datasets and intuitive suite of search, identification and download services, represent a truly FAIR (Findable, Accessible, Interoperable and Reusable) resource that enables researchers to easily identify and quickly obtain the key datasets needed for their COVID-19 research
