Proposed New Framework Scheme for Path Loss in Wireless Body Area Network

Recent technical developments in wi-fi networking, microelectronic integration and programming, sensors and the Internet have enabled us to create and enforce a range of new framework schemes to fulfil the necessities of healthcare-related wireless body area network (WBAN). WBAN sensors continually screen and measure patients’ indispensable signs and symptoms, and relay them to scientific monitoring for diagnosis. WBAN has a range of applications, the most necessary of which is to help patients suffering diseases to stay alive. The quality instance is the coronary heart implant sensor, whose video display unit monitors coronary heart sign and continuously transmits it. This setup eliminates the need for patients to visit the medical doctor frequently. Instead, they can take a seat at home and acquire an analysis and prescription for the disease. Today, a sizable effort is being made to increase low-power sensors and gadgets for utility in WBAN. A new framework scheme that addresses route loss in WBAN and discusses its penalties in depth is endorsed in this paper. The new framework scheme is applied to three case scenarios to obtain parameters by measuring vital information about the human body. On-body and intrabody conversation simulations are conducted. On-body conversation findings show that the route loss between transmitter and receiver rises with growing distance and frequency

An Uncommon Case of Splenic Abscess with Gangrenous Gas Necrosis

Splenic abscess is a rare clinical entity with diagnostic challenges. Though rare, it is potentially a life-threatening clinical condition with high mortality reaching more than 70%. The common signs and symptoms include the triad of fever, left upper quadrant tenderness, and leukocytosis. Early diagnosis, however, can readily be made by the combination of clinical features, abdominal ultrasonography (USG), and computed tomography (CT). The management of splenic abscess includes medical therapy, CT-guided percutaneous aspiration, and splenectomy. We, hereby, present a rare case of splenic abscess with gangrenous gas necrosis, who underwent splenectomy.

Comparison of efficacy of topical alcaftadine (0.25%) versus olopatadine (0.1%) in allergic conjunctivitis

The most common atopic ocular condition in clinical practice is allergic conjunctivitis. One of the preferred treatment options for allergic Conjunctivitis is anti histamines eye drops. The study purpose is to compare the clinical efficacy between topical alcaftadine 0.25% and olopatadine hydrochloride 0.1% in allergic conjunctivitis patients.A prospective, randomized, open label, parallel group, comparative study was conducted on 60 Patients with bilateral allergic conjunctivitis (30 in each group) after taking an informed written consentand was evaluated from May 2018 to November 2018. Patients were randomized into 2 groups of 30 each, group A received topical Alcaftadine 0.25% twice daily and patients in Group B received topical olopatadine hydrochloride 0.1% twice daily for 2 weeks. The patients were evaluated on first visit (baseline) followed by 7 and 14 day after starting the treatment. At each visit signs and symptoms were evaluated and rated using a scale from 0-3(0-Absent, 1- mild, 2 moderate and 3- severe). The change from baseline in the mean scores of itching, hyperemia, photophobia and tearing on day 14 is the primary outcome variable.: The signs and symptoms of allergic conjunctivitis were reduced by 2 weeks from baseline after using both the drugs. Relative significant efficacy was achieved in alcaftadine group for Itching, hyperemia and photophobia, but not for tearing (p=0.3). When compared to 0.1% olopatadine hydrochloride, 0.25% alcaftadine is more effective in reducing the symptoms of all types of allergic conjunctivitis except those mentioned in exclusion criteria.

This review highlights the role of dental practitioners to diagnose the early signs of oral lesions in COVID-19 infection. They can play an important role in managing pain, giving support to patient and improving the quality of life, by becoming a part of multi-disciplinary team to fight against this global pandemic.

Miller fisher syndrome – A rare complication of covid-19 infection

The COVID-19 virus can present with various neurological signs and symptoms involving both the central and peripheral nervous systems. Miller Fisher syndrome (M.F.S.), a variant of Landry Guillain Barre Syndrome (L.G.B.S.), presents with ataxia, areflexia, and ophthalmoplegia. It can develop during and after COVID-19 illness. We are reporting a case of the Miller Fisher variant of L.G.B.S. following a COVID-19 infection. We found no difference in clinical presentation, electrophysiological studies, severity, recovery, and treatment in our patient compared to a non-covid related M.F.S. Our goal is to add a case of the COVID-19-associated Miller Fisher variant of L.G.B.S. to already existing limited literature through this case report.

Epidemiology and Clinicopathologic Study of Nonneoplastic Cystic Lesions of the Central Nervous System at a Tertiary Care Center

Background Nonneoplastic cysts of brain are a diverse group of benign lesions with variable etiopathogenesis. Due to different site and histogenesis, these lesions have wide clinicopathologic spectrum. Objective The study was performed to evaluate epidemiology and clinicopathologic spectrum of nonneoplastic central nervous system (CNS) cysts highlighting the role of histopathology in the diagnosis as well as to compare the data with other institution’s data available in literature. Materials and Methods All nonneoplastic CNS cysts reported from January 2013 to June 2020 in the Department of Pathology of Sawai Man Singh Medical College, Jaipur, were retrieved and reviewed. The data were evaluated for age, site, cyst wall lining, nature of cyst contents, and location (intracranial and spinal), using SPSS software version 20.0. Results A total of 255 cases were reviewed with an incidence of 4.96% and an age range of 2 to 74 years with slight male preponderance. Among them there were 157, 34, 26, 24, and 2 cases of epidermoid, arachnoid, dermoid, colloid, and glioependymal cysts, respectively, and 1 case of perineural cyst. Infective cysts were much less common than noninfective cysts, accounting for two cases of neurocysticercosis and hydatid cysts each. All cyst types mainly presented with signs and symptoms of a mass lesion. Conclusion Nonneoplastic cyst mainly presented like a CNS mass lesion with overlapping clinical features, and image finding revealing the key role of histopathological analysis. Epidermoids were the most common type of these cysts in the present series followed by the arachnoid cysts.

Unilateral absence of internal carotid artery: A rare case report

Unilateral absence of internal carotid artery (ICA) is a rare congenital anomaly. We present the case of a 35-year-old man with episodes of recurrent strokes in the past and now presenting with right-sided upper limb weakness. Radiological diagnostic workup revealed a thin left ICA in the neck with non-visualization beyond petrous bone in the intracranial course. The ipsilateral brain parenchyma is supplied by vessels from the contralateral side of the Circle of Willis. As the patient had no evidence of a cerebrovascular accident on radiological evaluation and no neurological signs and symptoms, he was discharged with anticoagulant medications with the advice of follow-up. This is the first report to describe a case of ICA agenesis with a pattern of collateral circulation that doesn’t fit any of the six types described by Lie.

A Portrait of SARS-CoV-2 Infection in Patients Undergoing Hematopoietic Cell Transplantation: A Systematic Review of the Literature

The management of COVID-19 in hematopoietic cell transplant (HCT) recipients represents a special challenge given the variable states of immune dysregulation and altered vaccine efficacy in this population. A systematic search (Ovid Medline and Embase on 1 June 2021) was needed to better understand the presenting features, prognostic factors, and treatment options. Of 897 records, 29 studies were identified in our search. Most studies reporting on adults and pediatric recipients described signs and symptoms that were typical of COVID-19. Overall, the mortality rates were high, with 21% of adults and 6% of pediatric HCT recipients succumbing to COVID-19. The factors reported to be associated with increased mortality included age (HR = 1.21, 95% CI 1.03–1.43, p = 0.02), ICU admission (HR = 4.42, 95% CI 2.25–8.65, p < 0.001 and HR = 2.26, 95% CI 1.22–4.20, p = 0.01 for allogeneic and autologous HCT recipients), and low platelet count (OR = 21.37, 95% CI 1.71–267.11, p = 0.01). Performance status was associated with decreased mortality (HR = 0.83, 95% CI 0.74–0.93, p = 0.001). A broad range of treatments was described, although no controlled studies were identified. The risk of bias, using the Newcastle–Ottawa scale, was low. Patients undergoing HCT are at a high risk of severe morbidity and mortality associated with COVID-19. Controlled studies investigating potential treatments are required to determine the efficacy and safety in this population.

Prognostic Value of T1 Mapping and Feature Tracking by Cardiac Magnetic Resonance in Patients With Signs and Symptoms Suspecting Heart Failure and No Clinical Evidence of Coronary Artery Disease

Background The ability of left ventricular ejection fraction (LVEF) and late gadolinium enhancement (LGE) by cardiac magnetic resonance for risk stratification in suspected heart failure is limited. We aimed to evaluate the incremental prognostic value of cardiac magnetic resonance‐assessed extracellular volume fraction (ECV) and global longitudinal strain (GLS) in patients with signs and symptoms suspecting heart failure and no clinical evidence of coronary artery disease. Methods and Results A total of 474 consecutive patients (57±21 years of age, 56% men) with heart failure‐related symptoms and absence of coronary artery disease underwent cardiac magnetic resonance. After median follow‐up of 18 months, 59 (12%) experienced the outcome of all‐cause death or heart failure hospitalization (DeathCHF). In univariate analysis, cardiac magnetic resonance‐assessed LVEF, LGE, GLS, and ECV were all significantly associated with DeathCHF. Adjusted for a multivariable baseline model including age, sex, LVEF and LGE, ECV, and GLS separately maintained a significant association with DeathCHF (ECV, hazard ratio [HR], 1.44 per 1 SD increase; 95% CI 1.13–1.84; P =0.003, and GLS, HR, 1.78 per 1 SD increase; 95% CI, 1.06–2.96; P =0.028 respectively). Adding both GLS and ECV to the baseline model significantly improved model discrimination (C statistic from 0.749 to 0.782, P =0.017) and risk reclassification (integrated discrimination improvement 0.046 [0.015–0.076], P =0.003; continuous net reclassification improvement 0.378 [0.065–0.752], P <0.001) for DeathCHF, beyond LVEF and LGE. Conclusions In patients with signs and symptoms suspecting heart failure and no clinical evidence of coronary artery disease, joint assessment of GLS and ECV provides incremental prognostic value for DeathCHF, independent of LVEF and LGE.
