Scrub typhus, an acute febrile infectious disease prevalent in the ‘tsutsugamushi triangle’, is a mite-born rickettsial zoonosis, caused by Orientia tsutsugamushi. The clinical presentation is protean and involves multiple organ systems of the body, including central and peripheral nervous systems. We report a 22-year-old previously healthy Indian woman who presented with clinical (confusion, excessive sleepiness, cognitive dysfunction and focal seizures) and neuroimaging features of limbic encephalitis. After exclusion of common infectious, autoimmune and paraneoplastic causes, she was diagnosed with scrub typhus associated encephalitis, which responded to doxycycline and azithromycin therapy.

Collective Information

Scrub typhus is one the most important re-emerging infectious disease, and perhaps, the most important bacterial disease. Caused by Orientia tsutsugamushi, it is transmitted through the bite of mites belonging to the genus Leptotrombidium, in which the bacteria are obligate parasites. Though the mites are natural ectoparasites of rodents and other animals, in which there is no disease, opportunistic infection to humans gives rise to a serious disease. Known to Japanese physicians as tsutsugamushi (insect disease), human infection is caused by the larvae of trombiculid mites, the fact established by Mataro Nagayo and co-workers established in 1917. The pathogen was discovered by Naosuke Hayashi in 1920. In Mizoram, the disease has been rampant since 2011. This paper summarises available data on the prevalence of the infection in different districts base on collective information from various sources. Records between 2012 and 2018 show that over a thousand people had been infected and 35 people had died of the disease.

New Biomarkers

Parkinson’s disease (PD) is a highly prevalent and irreversible neurodegenerative disorder that is typically diagnosed in an advanced stage. Currently, there are no approved biomarkers that reliably identify PD patients before they have undergone extensive neuronal damage, eliminating the opportunity for future disease-modifying therapies to intervene in disease progression. This unmet need for diagnostic and therapeutic biomarkers has fueled PD research for decades, but these efforts have not yet yielded actionable results. Recently, studies exploring mechanisms underlying PD progression have offered insights into multisystemic contributions to pathology, challenging the classic perspective of PD as a disease isolated to the brain. This shift in understanding has opened the door to potential new biomarkers from multiple sites in the body. This review focuses on emerging candidates for PD biomarkers in the context of current diagnostic approaches and multiple organ systems that contribute to disease.

Salt Sensitive Hypertension

Over 26,000 manuscripts have been published dealing with endothelins since their discovery 25 years ago. These peptides, and particularly endothelin-1 (ET-1), are expressed by, bind to, and act on virtually every cell type in the body, influencing multiple biological functions. Among these actions, the effects of ET-1 on arterial pressure and volume homeostasis have been most extensively studied. While ET-1 modulates arterial pressure through regulation of multiple organ systems, the peptide's actions in the kidney in general, and the collecting duct in particular, are of unique importance. The collecting duct produces large amounts of ET-1 that bind in an autocrine manner to endothelin A and B receptors, causing inhibition of Na+ and water reabsorption; absence of collecting duct ET-1 or its receptors is associated with marked salt-sensitive hypertension. Collecting duct ET-1 production is stimulated by Na+ and water loading through local mechanisms that include sensing of salt and other solute delivery as well as shear stress. Thus the collecting duct ET-1 system exists, at least in part, to detect alterations in, and maintain homeostasis for, extracellular fluid volume. Derangements in collecting duct ET-1 production may contribute to the pathogenesis of genetic hypertension. Blockade of endothelin receptors causes fluid retention due, in large part, to inhibition of the action of ET-1 in the collecting duct; this side effect has substantially limited the clinical utility of this class of drugs. Herein, the biology of the collecting duct ET-1 system is reviewed, with particular emphasis on key issues and questions that need addressing.

Microscopic polyangiitis (MPA) is an idiopathic autoimmune disease characterized by systemic vasculitis. While the lungs and kidneys are the major organs affected by MPA, it is known to involve multiple organ systems throughout the body. Temporal artery involvement is a very rare finding in MPA. This report presents a patient whose initial presentation was consistent with giant cell arteritis but was ultimately found to have microscopic polyangiitis. It highlights the importance of considering alternative types of vasculitis in the differential diagnosis for patients with atypical temporal artery biopsy findings.

Endocannabinoid synthesis in the human body is naturally occurring and on-demand. It occurs in response to physiological and environmental stimuli, such as stress, anxiety, hunger, other factors negatively disrupting homeostasis, as well as the therapeutic use of the phytocannabinoid cannabidiol and recreational use of exogenous cannabis, which can lead to cannabis use disorder. Together with their specific receptors CB1R and CB2R, endocannabinoids are major components of endocannabinoid-mediated neuromodulation in a rapid and sustained manner. Extensive research on endocannabinoid function and expression includes studies in limbic system structures such as the hippocampus and amygdala. The wide distribution of endocannabinoids, their on-demand synthesis at widely different sites, their co-existence in specific regions of the body, their quantitative differences in tissue type, and different pathological conditions indicate their diverse biological functions that utilize specific and overlapping pathways in multiple organ systems. Here, we review emerging evidence of these pathways with a special emphasis on the role of endocannabinoids in decelerating neurodegenerative pathology through neural networks initiated by cells in the main olfactory bulb.

ABSTRACTSepsis is a severe infectious disease with high mortality, and it occurs when chemicals released in the bloodstream to fight an infection trigger inflammation throughout the body and it can cause a cascade of changes that damage multiple organ systems, leading them to fail, even resulting in death. In order to reduce the possibility of sepsis or infection antiseptics are used and process is known as antisepsis. Antiseptic peptides (ASPs) show properties similar to antigram-negative peptides, antigram-positive peptides and many more. Machine learning algorithms are useful in screening and identification of therapeutic peptides and thus provide initial filters or built confidence before using time consuming and laborious experimental approaches. In this study, various machine learning algorithms like Support Vector Machine (SVM), Random Forest (RF), K-Nearest Neighbour (KNN) and Logistic Regression (LR) were evaluated for prediction of ASPs. Moreover, the characteristics physicochemical features of ASPs were also explored to use them in machine learning. Both manual and automatic feature selection methodology was employed to achieve best performance of machine learning algorithms. A 5-fold cross validation and independent data set validation proved RF as the best model for prediction of ASPs. Our RF model showed an accuracy of 97%, Matthew’s Correlation Coefficient (MCC) of 0.93, which are indication of a robust and good model. To our knowledge this is the first attempt to build a machine learning classifier for prediction of ASPs.

Coronavirus disease 2019 (COVID-19) has become one of the most prevalent and significant global health concerns since its origin in Wuhan, China in the December 2019. As on 05th April, this disease has affected over 131 million people and has resulted in more than 2.85 million deaths worldwide till date. The disease is transmitted from the infected patients to the people in close contact through respiratory droplets. There are a number of factors which affect the transmission of this disease. The clinical presentation of COVID-19 can range from asymptomatic infections to critical disease leading to respiratory failure, septic shock and multiple organ failure. The disease essentially affects the respiratory system but other organ systems may also be involved. Currently, the therapeutic management of the disease is based on the severity of the infection and employs various strategies like monoclonal antibodies, corticosteroids, antivirals, stem cell therapy and immunomodulators. Scientists and researchers all around the world have raced against the time and developed a number of vaccines for COVID-19.  At present, there are many COVID-19 vaccines, which have been authorized or approved for use by the regulators of the different countries. This article reviews the current published data on the COVID-19 transmission, clinical presentations, treatments and vaccines.

Extracorporeal shock wave lithotripsy (ESWL) is an effective treatment modality in the minimal invasive management of urinary system stone disease. Although the majority of the complications occuring after ESWL are minor (most common ones are gross haematuria, pain, perinephritic hematoma); bacteriuria may also occur in some cases which sometimes can lead to sepsis and even metastatic abscess formation in a very rare part of the cases treated. In this rare situation infection agent spreads quickly via hematogenous route and causes abscess formation in different parts of the body. Majority of such cases usually have an underlying systemic disease like diabetes mellitus (DM), malignancy, HIV or steroid use which lead to disruption of immune system functions. Abscess formation following ESWL is extremely rare and usually limited with some case reports published in the literature. Herein, we present a diabetic case with formation of multiple abscess foci in kidney, as well as in lungs and liver following ESWL. The patient was first admitted to our emergency department with high fever and respiratory distress and misdiagnosed as metastatic tumor foci based on radiologic findings. To the best of our knowledge, our case is the first one in the literature in whom simultanous abscess formation in multiple organ systems has been documented following an otherwise uneventful ESWL.

Hypoxic Respiratory Failure

The systemic vasculitides are multifocal diseases characterized by the presence of blood vessel inflammation in multiple organ systems. Their clinical presentation is variable extending from self-limited illness to critical complications including diffuse alveolar hemorrhage and glomerulonephritis. Alveolar hemorrhage is a lifethreatening manifestation of pulmonary vasculitis that can rapidly progress into acute respiratory failure requiring ventilatory support. We present the case of a 74-year-old patient admitted to the Intensive Care Unit with severe hypoxic respiratory failure and diffuse alveolar infiltrates in chest imaging that was later diagnosed as antineutrophil cytoplasmic antibodies-associated vasculitis. The report highlights the importance of differentiate between alveolar hemorrhage and acute respiratory distress syndrome of other etiology because alveolar hemorrhage is reversible with prompt initiation of treatment.
