A Case Report of Simultaneous Intracranial Hemorrhage and Cerebral Venous Sinus Thrombosis in a Young Indian Male: Diagnostic and Therapeutic Challenges.

This case report discusses the intricate diagnostic and therapeutic challenges faced by a 23-year-old Indian male who presented with altered consciousness, a holo-cranial headache, right-sided hemiparesis, and subsequent neurological symptoms. The patient's dietary habits, leading to vitamin B12 and folic acid deficiencies resulting in hyperhomocysteinemia, along with binge alcohol drinking leading to dehydration, were identified as the main causes of cerebral venous sinus thrombosis (CVST) in this case. The case was complicated by an additional cerebral hemorrhage. The patient received a comprehensive treatment regimen involving antiepileptic medications, intravenous fluids, and anticoagulation therapy. A decline in the Glasgow Coma Scale score prompted further interventions. Collaborative decision-making, involving neurologists, neurosurgeons, and the patient's relatives, steered the treatment course, ultimately favoring continued medical management over decompression surgery. Notably, the patient exhibited remarkable progress in mobility, achieving the ability to walk with support by the end. This case report contributes valuable insights to the understanding of CVST, emphasizing the significance of nutritional considerations, especially in vegetarians, and underscoring the importance of thorough diagnostic evaluations in complex clinical scenarios.

Tuberculosis in a Liver Cirrhosis Patient: A Management Conundrum.

This case report delves into the intricate challenges of managing tuberculosis (TB) in a 70-year-old male with decompensated chronic liver disease (DCLD) and a history of endoscopic variceal ligation. The patient, initially presenting with symptoms such as black-colored stools, breathlessness, and weight loss, was diagnosed with right-sided pneumonia alongside DCLD. Despite the administration of standard beta-lactam plus macrolide antibiotics, the patient exhibited no improvement. Subsequent bronchoscopy revealed Mycobacterium tuberculosis (MTB), prompting the initiation of first-line anti-tubercular therapy. However, the hepatotoxic response necessitated a switch to a modified regimen with non-hepatotoxic drugs, emphasizing the challenge of managing TB in cirrhotic patients. Effective management of MTB infection involves personalized administration of anti-TB drugs, taking into account the individual's chronic liver disease status. This case underscores the importance of treating tuberculosis in liver cirrhosis patients based on the Child-Turcotte-Pugh score. A tailored and vigilant approach is indispensable for the successful management of MTB infection.

Managing Ventricular Wall Rupture as a Complication of Late Presentation MI in a Complex Patient with Ankylosing Spondylitis.

Ventricular free wall rupture is an infrequent but serious complication of myocardial infarction with high mortality despite surgical intervention. In recent years with the COVID-19 pandemic, observational studies have reported a rise in this complication most likely due to patient hesitation in seeking urgent medical assistance for fear of contracting COVID-19 in a hospital setting. This case report highlights the early recognition and diagnosis of ventricular wall rupture by the heart team with a good surgical outcome in a complex patient with ankylosing spondylitis. Ventricular rupture should be considered in deteriorating patients presenting with suspicion of late presentation myocardial infarction. Clinicians in the post-COVID-19 era should expect to see these complications more frequently.

Antibacterial activity of Ricinus communis plant extract against antibiotic resistant Helicobacter pylori and Gluconobacter oxydans isolated from fresh apple juices samples

Abstract Bacteria were isolated from samples of Fresh Apple juices from shops of three different localities of Lahore. Analysis of samples from Liberty, Anarkali and Yateem khana Markets show different levels of contamination. There were pathogenic and non-pathogenic bacteria in all samples and were identified by the morphological and biochemical tests. Most of the plasmids of pathogenic bacteria were 4kb in their molecular size. Ribotyping of 16S ribosomal RNA gene sequencing was done to confirm Helicobacter pylori strain and Gluconobacter oxydans. The highest sensitivity of 210mm was shown by Enterobacter sp. against Aztheromysine disk (15µg) while Micrococcus sp. was highly resistant against all of the Antibiotics applied. The antibiotic resistance of pathogenic bacteria was also checked against Ricinus communis plant's extracts, all isolated bacterial pathogens were resistant but only, E.coli was inhibited at 300µl of the extracts. Presence of pathogenic bacteria in Apple juice samples was due to contamination of sewage water in drinking water while some of these pathogenic bacteria came from Apple's tree and other from store houses of fruits.

Dengue and chikungunya infections are increasing globally, especially in India. While the majority of patients settle with symptomatic management, some develop life-threatening complications. Here we discuss a case of co-infection between dengue virus (DENV-2) and chikungunya virus (CHIKV) in a young Indian male who presented with an acute febrile illness that progressed to multi-organ dysfunction involving the hepatic, nervous, respiratory, and hematological systems. We discuss the management of this complicated case and attempt to generate awareness regarding the severity of co-infection by these viruses.

A Case of Acquired Angioedema Leading to the Diagnosis of Systemic Lupus Erythematosus.

We describe a case of a young 32-year-old Indian female who presented with a solitary symptom of facial swelling for two months. The patient's blood test results showed hypocomplementemia and C1 INH deficiency and fell into the "third type" of acquired angioedema (AAE), leading to the diagnosis of systemic lupus erythematosus (SLE), with SLE inactivity at the time of presentation, which makes this an interesting case due to the rarity of such findings in our clinical settings.

Consequences of Irregular Tuberculosis Treatment: A Case Report of Destroyed Lung Syndrome.

Destroyed lung syndrome (DLS) refers to the irreversible and complete destruction of lung tissue, often due to chronic or recurrent lung infections. Pulmonary tuberculosis (PTB) is a prominent cause of this condition, particularly prevalent in regions burdened by high PTB rates. This report delineates the case of a 60-year-old Indian male who presented with DLS as a consequence of a history of irregular PTB treatment. The patient complained of a productive cough, hemoptysis, fever, and dyspnea. A comprehensive evaluation confirmed the diagnosis, prompting the re-initiation of antitubercular therapy. This case report highlights the challenges and consequences of irregular PTB therapy leading to severe lung damage, emphasizing the significance of prompt and consistent treatment in preventing such debilitating outcomes.

AKU Giant Pituitary Adenoma Score: A Novel Scoring System to Predict the Outcomes of Surgery for Giant Pituitary Adenomas.

Background No scoring system is available to predict the extent of resection of giant pituitary adenomas (GPAs) based on magnetic resonance imaging (MRI) parameters. We developed a novel AKU Giant Pituitary Adenoma (AGPA) score and assessed the predictive ability of the scoring system concerning the extent of resection of GPAs. Methodology We retrospectively collected data of patients presenting with GPAs and used our scoring system to assess the surgical resection of these tumors. The Lundin-Pederson (ABC/2) method was used to calculate the pre- and post-resection tumor volume. The relationship between the extent of resection and the AGPA score was assessed using linear regression. The AGPA score considered the tumor's extension into various planes. The maximum total score was 9. Results The scoring system was applied to 45 patients with GPA who underwent surgical resection. The mean resected tumor volume (%) was 82.0 ± 16.7, and the overall mean AGPA score was 4.2 ± 0.8. The pairwise correlation between the resected tumor volume and the overall AGPA scores showed a strong inverse association (r = -0.633, p < 0.001). A significant difference was detected between the estimated scores of 3 and 5 and 4 and 5 (p < 0.001). Conclusions AGPA score is inversely related to the extent of the tumor to be resected, which would help surgeons predict the amount of tumor resection possible as well as predict the difficulty of surgery and plan optimal preoperative patient counseling. In addition, it can predict if staging and a transcranial approach are required.

Acute Myocarditis Secondary to Paediatric Inflammatory Multisystem Syndrome Temporally Associated With COVID-19 Infection.

A 17-year-old female, who was previously fit and well with no preexisting health conditions, presented with a four-day history of worsening shortness of breath and diarrhoea. She had recent close contact with a relative diagnosed with COVID-19. On clinical examination, she was drowsy, hypotensive, tachycardic, tachypnoeic, and pyrexial. Her blood tests showed elevated inflammatory markers and lymphopenia. She underwent a transthoracic echocardiogram, which confirmed a severely impaired left ventricular (LV) systolic function with an ejection fraction of 35%. An initial impression of acute viral myocarditis was made. Three separate polymerase chain reaction (PCR) tests for SARS-CoV-2 RNA were performed, but they all returned negative. The patient was not responding to initial therapy. Therefore, the regional paediatrics hospital was consulted, and a diagnosis of paediatric inflammatory multisystem syndrome temporally associated with COVID-19 (PIMS-TS) was made, based on similar regional presentations. The patient was administered IV immunoglobulin therapy, to which she responded very well. Following a five-day hospital stay, the patient was discharged home as medically stable. A repeat transthoracic echocardiogram (TTE) showed recovery of the LV systolic function to 62%. Few cases have been reported on myocardial involvement in young patients with PIMS-TS. This case report highlights the initial presentation, medical care, and clinical course of this patient.

Knowledge of Autism Spectrum Disorder Among 2nd to 4th Phase MBBS Students of Bangladesh.

Autism spectrum disorder (ASD), being one of the fastest-growing disabilities in children, is an omnipresent, immutable neurodevelopmental disorder characterized by impaired socialization, impaired verbal and non-verbal communication, restricted interests, and repetitive behaviour patterns. A descriptive cross-sectional study was conducted from 30 October to 30 November 2019 among the MBBS students of 21 medical colleges in Bangladesh to assess their knowledge of autism. The 'Knowledge about Childhood Autism among Health Workers (KCAHW)' questionnaire containing 19 item questions divided into four domains was used. The total median score in the KCAHW questionnaire is 13 out of 19. The final total of respondents numbered 483. There were 215 (44.51%) male and 268 (55.49%) female students. Among 21 medical colleges, 10 are situated in the Dhaka district and 11 outside Dhaka; 14 medical colleges were public, and seven were private. The study shows that students' knowledge of autism spectrum disorder (ASD) is not up to the mark. While assessing the knowledge in each domain, Domain 4 (knowledge regarding nature, comorbidities, and onset) shows that only 32.6% of students of 4th phase and 21.5% of other phases have scored more than the median value, revealing that medical students were not familiar with nature, comorbidities, and the onset of ASD. It can be reliably diagnosed before two years of age, but the practical scenario is a different picturesque. Thus, medical students should have bona fide knowledge to diagnose this progressively prevailing disorder at the earliest possible time. We hope this study's aftermath will significantly impact the integrity and diversity of autism spectrum disorder.

International Neurotrauma Training Based on North-South Collaborations: Results of an Inter-institutional Program in the Era of Global Neurosurgery.

Objective: Shortage of general neurosurgery and specialized neurotrauma care in low resource settings is a critical setback in the national surgical plans of low and middle-income countries (LMIC). Neurotrauma fellowship programs typically exist in high-income countries (HIC), where surgeons who fulfill the requirements for positions regularly stay to practice. Due to this issue, neurosurgery residents and medical students from LMICs do not have regular access to this kind of specialized training and knowledge-hubs. The objective of this paper is to present the results of a recently established neurotrauma fellowship program for neurosurgeons of LMICs in the framework of global neurosurgery collaborations, including the involvement of specialized parallel education for neurosurgery residents and medical students. Methods: The Global Neurotrauma Fellowship (GNTF) program was inaugurated in 2015 by a multi-institutional collaboration between a HIC and an LMIC. The course organizers designed it to be a 12-month program based on adapted neurotrauma international competencies with the academic support of the Barrow Neurological Institute at Phoenix Children's Hospital and Meditech Foundation in Colombia. Since 2018, additional support from the UK, National Institute of Health Research (NIHR) Global Health Research in Neurotrauma Project from the University of Cambridge enhanced the infrastructure of the program, adding a research component in global neurosurgery and system science. Results: Eight fellows from Brazil, Venezuela, Cuba, Pakistan, and Colombia have been trained and certified via the fellowship program. The integration of international competencies and exposure to different systems of care in high-income and low-income environments creates a unique environment for training within a global neurosurgery framework. Additionally, 18 residents (Venezuela, Colombia, Ecuador, Peru, Cuba, Germany, Spain, and the USA), and ten medical students (the United Kingdom, USA, Australia, and Colombia) have also participated in elective rotations of neurotrauma and critical care during the time of the fellowship program, as well as in research projects as part of an established global surgery initiative. Conclusion: We have shown that it is possible to establish a neurotrauma fellowship program in an LMIC based on the structure of HIC formal training programs. Adaptation of the international competencies focusing on neurotrauma care in low resource settings and maintaining international mentoring and academic support will allow the participants to return to practice in their home-based countries.

Heart rate variability in patients with atrial fibrillation and hypertension.

BACKGROUND: Atrial fibrillation (AF) and hypertension are independently associated with impaired autonomic function determined using heart rate variability (HRV). As these conditions frequently co-exist, we sought to determine whether AF would worsen HRV in hypertensive patients. DESIGN: We studied HRV in AF (and hypertension) (n = 61) and hypertension control group (n = 33). The AF (and hypertension) group was subdivided into permanent AF (n = 30) and paroxysmal AF (n = 31) and re-studied. Time-domain, frequency-domain and nonlinear measures of HRV were determined. Permanent AF group (n = 30) was followed up after 8 weeks following optimisation of their heart rate and blood pressure (BP). RESULTS: Time-domain and nonlinear indices of HRV were higher in AF (and hypertension) group compared to hypertensive controls (P ≤ .01). Time-domain and nonlinear indices of HRV were higher in permanent AF group compared to paroxysmal AF (P ≤ .001). Permanent AF was an independent predictor of HRV on multivariable analysis (P = .006). Optimisation of heart rate and BP had no significant impact on HRV in permanent AF. CONCLUSIONS: AF, independent of hypertension, is characterised with marked HRV and is possibly related to vagal tone. HRV is higher in permanent AF compared to paroxysmal AF suggesting evident autonomic influence in the pathophysiology of permanent AF. Modulation of autonomic influence on cardiovascular system should be explored in future studies.

3D metal lattice structure manufacturing with continuous rods.

In this paper, a new possibility of fabricating a metal lattice structure with a continuous rod is demonstrated. A multi-layer, periodic, and aperiodic lattice structure can be manufactured with a continuous thin rod by bending it with a repetitive pattern. However, joining their nodes are challenging and an important problem to solve. This paper is investigating the joining of nodes in a loose lattice structure by delivering materials through the dipping process. Both liquid state (epoxy) and solid-state (inorganic particles) joining agents are considered for polymer-metal and metal-metal bonding, respectively. Liquid Carrier Systems (LCS) are designed considering their rheological behavior. We found 40% solid loading with the liquid carrier system provides sufficient solid particles transfer at dipping and join the lattice node using transient liquid phase bonding (TLP). 3D metal lattice structures are constructed, and their mechanical properties are investigated. The lattice structure shows comparable strength even with smaller relative density (< 10%). The strength and elastic modulus of all the fabricated samples decreases with the increase in cell size, which is consistent with the traditional wisdom.

A Novel Rapid Manufacturing Process for Metal Lattice Structure.

A novel lattice structure manufacturing process is proposed in this article, which has the potential to overcome the manufacturing shortcomings of small-scale metal lattice structure. The proposed hierarchical process has four segments: Design, Bending, Dip, and Join (DBDJ). The proposed research use one-dimensional metallic wires/rods instead of powder, two-dimensional sheet, or liquid metal, which is highly transformative than the status quo. The topology-based design technique is focused to construct the lattice structure using a continuous thin rod. The layers are stacked in an additive manner to construct the three-dimensional lattice structure. The dip-coating meditate material transfer facilitates the node joining using transient liquid phase diffusion bonding, and hence, the manufacturing of the complex lattice structure is performed. The research framework provides a unique and holistic approach from design to manufacturing for realizing small-scale metallic lattice structure. A range of multiscale lattice structure is manufactured with the proposed DBDJ process. Very low relative density (∼3.8%) unit cell is achieved, and compressive tests demonstrate no failure at the joining node, which is reported in this article.

A greater burden of atrial fibrillation is associated with worse endothelial dysfunction in hypertension.

Atrial fibrillation (AF) and hypertension often co-exist and both are associated with endothelial dysfunction. We hypothesised that AF would further worsen endothelium-dependent flow-mediated dilatation (FMD) in hypertension patients compared to those without AF. In a cross-sectional comparison, we measured brachial artery diameter at rest and during reactive hyperaemia following 5 min of arterial occlusion in two patient groups: AF (and hypertension) (n = 61) and hypertension control groups (n = 33). The AF (and hypertension) subgroups: permanent AF (n = 30) and paroxysmal AF (n = 31) were also assessed. The permanent AF patients received heart rate and blood pressure (BP) control optimisation and were then followed up after eight weeks for repeat FMD testing. There was no significant difference in FMD between AF (and hypertension) group and hypertension control group (4.6%, 95% CI [2.6-5.9%] vs 2.6%, 95% CI [1.9-5.3%]; p = 0.25). There was a significant difference in FMD between permanent AF and paroxysmal AF groups (3.1%, 95% CI [2.3-4.8%] vs 5.9%, 95% CI [4.0-8.1%]; p = 0.02). Endothelium-dependent FMD response showed a non-significant improvement trend following eight weeks of heart rate and BP optimisation (3.1%, 95% CI [2.3-4.8%] (baseline) vs 5.2%, 95% CI [3.9-6.5%] (follow up), p = 0.09). Presence of AF generally does not incrementally worsen endothelial dysfunction in hypertension patients, although the duration and frequency of AF (paroxysmal AF to permanent AF) does lead to worsening endothelial function. Eight weeks of BP optimisation did not significantly improve endothelial dysfunction as measured by FMD.

Observations on clot properties in atrial fibrillation: Relation to renal function and choice of anticoagulant.

INTRODUCTION: Atrial fibrillation (AF) is associated with increased risk of stroke and thromboembolism. Patients with AF have a higher incidence of renal impairment, which may influence the risks of systemic thromboembolism or bleeding. We determined how different oral anticoagulants affect plasma clot properties and whether progressive renal dysfunction affects plasma clot properties in patients on warfarin. MATERIALS AND METHODS: We studied 257 patients with AF receiving oral anticoagulants. Furthermore, we recruited 192 separate patients with AF on warfarin and divided them in 4 groups based on estimated glomerular filtration rate (eGFR). Platelet poor plasma was prepared and clot formation and fibrinolysis was monitored kinetically up to 1 h. RESULTS: Rate of clot formation was significantly slower with dabigatran and rivaroxaban. Time between 50% clotting and 50% lysis was prolonged in patients receiving warfarin compared to NOACs. Time to 50% lysis from maximum absorbance was significantly shorter in patients receiving rivaroxaban. Time between 50% clotting and 50% lysis became significantly prolonged with worsening eGFR. Time to 50% lysis from maximum absorbance was prolonged as renal function worsened. CONCLUSIONS: Compared to warfarin, NOACs differently modulate coagulation and fibrinolysis under ex vivo conditions. Worsening renal function in AF patients on warfarin prolongs fibrinolysis, potentially increasing the risk of thrombosis.
