Navigating the Complexity: A Comprehensive Review of Hemophagocytic Lymphohistiocytosis Associated With Dengue Infection.

Hemophagocytic lymphohistiocytosis (HLH) associated with dengue infection presents a unique challenge in clinical practice due to its rarity, rapid progression, and overlapping clinical features. This comprehensive review navigates the complexity of HLH-dengue syndrome by examining its pathophysiology, clinical manifestations, diagnostic criteria, and therapeutic strategies. HLH, characterized by uncontrolled immune activation and cytokine dysregulation, can occur as a secondary complication of dengue infection, leading to severe multiorgan dysfunction and high mortality if not promptly recognized and treated. The review underscores the significance of early diagnosis through vigilant clinical monitoring and appropriate diagnostic tests, such as bone marrow examinations and genetic studies. Collaboration between infectious disease specialists, hematologists, and critical care teams is essential for optimal management. Despite advancements in understanding HLH-dengue syndrome, further research is needed to elucidate its underlying mechanisms and explore novel treatment approaches. This review provides insights into the clinical implications of HLH-dengue syndrome and emphasizes the importance of a multidisciplinary approach to improve patient outcomes in this challenging clinical scenario.

A Case of Bilateral Renal Infarct Due to Left Ventricular Thrombus.

Renal infarction is an uncommon illness that can have serious side effects. Patients may be predisposed to the disease by factors including smoking, atrial fibrillation, thrombus, infective endocarditis, myocardial infarction, and prosthetic valves. Patients are most susceptible from 24 hours to 15 days after myocardial infarction, with an increased rate of left ventricular (LV) thrombus development, which raises the probability of thromboembolic events in the cerebrovascular system and might exacerbate morbidity and mortality rate. This can be diagnosed by two-dimensional echocardiography. Different risk factors can contribute to the development of an LV thrombus. Renal infarcts from LV clots are less common but can occur bilaterally in certain situations. A 30-year-old male diagnosed with anterior wall myocardial infarction presented at our hospital and was suspected to have bilateral renal infarcts, possibly due to the LV thrombi. The patient was managed on anti-thrombolytics and was reported to be doing well at a follow-up of one month.

Myasthenia Gravis Mimicking Status Asthmaticus: The Hidden Crisis.

Status asthmaticus is a severe form of aggravation of asthma, whereas myasthenia gravis (MG) is a rare neuromuscular condition characterised by exhaustion and muscle weakness. Myasthenic crisis can occasionally manifest with symptoms that resemble status asthmaticus, which can result in an incorrect diagnosis and ineffective therapy. In addition to discussing the therapeutic implications, this abstract attempts to draw attention to the difficulties in distinguishing between status asthmaticus and myasthenia crisis and the importance of diagnosing subtle signs of MG. In this case, we present a 55-year-old female, with a misdiagnosed case of bronchial asthma, who presented with shortness of breath at rest for two to three days and was suspected to have an acute exacerbating episode of asthma. She was later evaluated for non-respiratory causes of dyspnea on noticing subtle signs of ptosis and was found to have an active myasthenic crisis. Although this case presented typically as status asthmaticus, it did not respond to conventional treatment of it, and on the contrary, it worsened. Hence, it is necessary to look for subtle signs of MG and promptly differentiate it from other similar emergency events to help administer accurate treatment which can prove life-saving.

Unmasking Uremic Encephalopathy: Choreoathetoid Movements Mimicking Alcohol Withdrawal in a Person with an Alcohol Use Disorder.

Chorea is a disorder characterized by irregular, involuntary movements affecting the limbs, trunk, neck, or face. It can be a significant symptom in various neurologic diseases, including metabolic, autoimmune, and neurodegenerative conditions. The neural foundation that underlies the genesis of chorea appears to be fairly diverse, even though its pathophysiology is frequently associated with the malfunctioning of inhibitory circuits within the basal ganglia. Movement disorders such as tremors, myoclonus, ataxia, chorea, and Parkinsonism may arise due to renal dysfunction or complications from management like renal transplant and hemodialysis. Uremic encephalopathy is a rare but potentially life-threatening neurological complication of chronic kidney disease. We present a case of a 50-year-old male with a known history of chronic kidney disease and chronic alcoholism, who exhibited abnormal movements resembling chorea upon presentation. Initially suspected as alcohol withdrawal-related chorea, further evaluation revealed concurrent rising creatinine levels, acidosis, and hyperkalemia. Hemodialysis was initiated, resulting in a significant improvement in choreoathetoid movements. This case implies the importance of considering uremic encephalopathy in the differential diagnosis of movement disorders in patients with underlying kidney dysfunction, even in the context of chronic alcoholism.

The Application of Deep Learning to Electroencephalograms, Magnetic Resonance Imaging, and Implants for the Detection of Epileptic Seizures: A Narrative Review.

Epilepsy is a neurological disorder characterized by recurrent seizures affecting millions worldwide. Medically intractable seizures in epilepsy patients are not only detrimental to the quality of life but also pose a significant threat to their safety. Outcomes of epilepsy therapy can be improved by early detection and intervention during the interictal window period. Electroencephalography is the primary diagnostic tool for epilepsy, but accurate interpretation of seizure activity is challenging and highly time-consuming. Machine learning (ML) and deep learning (DL) algorithms enable us to analyze complex EEG data, which can not only help us diagnose but also locate epileptogenic zones and predict medical and surgical treatment outcomes. DL models such as convolutional neural networks (CNNs), inspired by visual processing, can be used to classify EEG activity. By applying preprocessing techniques, signal quality can be enhanced by denoising and artifact removal. DL can also be incorporated into the analysis of magnetic resonance imaging (MRI) data, which can help in the localization of epileptogenic zones in the brain. Proper detection of these zones can help in good neurosurgical outcomes. Recent advancements in DL have facilitated the implementation of these systems in neural implants and wearable devices, allowing for real-time seizure detection. This has the potential to transform the management of drug-refractory epilepsy. This review explores the application of ML and DL techniques to Electroencephalograms (EEGs), MRI, and wearable devices for epileptic seizure detection. This review briefly explains the fundamentals of both artificial intelligence (AI) and DL, highlighting these systems' potential advantages and undeniable limitations.

Predictors of Mortality in Hospitalized Patients With Pesticide Poisoning.

Background Organophosphorus poisoning (OPP) is a prevalent mortality rate that varies from 2% to 25% method of suicides worldwide. ICUs commonly employ various scoring systems such as the Glasgow Coma Scale (GCS), Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II), and International Programme on Chemical Safety (IPCS) Poison Severity Score (PSS) tools for risk stratification for mortality prediction scores and prognosis. This study aims to compare the predictive validity of these systems in hospitalized patients suffering from pesticide poisoning in a teaching hospital located in central India. Methods A prospective study design was utilized to gather relevant variables for calculating the GCS, APACHE II, SAPS II, and IPCS scales in patients affected by pesticide poisoning. Data on the administered doses of atropine and pralidoxime (PAM) were also recorded. Results We have identified several independent predictors of mortality among patients suffering from pesticide poisoning. The GCS (P=0.001), tracheostomy (P=0.001), APACHE II score (P=0.01), and SAPS II score (P=0.001) were all found to be significant indicators of mortality. Interestingly, the GCS demonstrated comparable predictive ability for mortality when compared to the APACHE II (0.82 (95% confidence interval (CI) 0.70 to 0.94)) and SAPS II (0.83 (95% CI 0.72 to 0.94)) scores, with no statistically significant difference (P=0.75) observed. Among the variables used in the IPCS PSS (GCS, heart rate, systolic blood pressure (BP), intubation, and pupil size), only GCS (P=0.05), and intubation (P=0.01) exhibited a significant association with mortality. Conclusions Our study determined that the GCS score, SAPS II, IPCS PSS, and APACHE II exhibited equal efficacy in predicting mortality. Notably, the GCS offered an added advantage due to its simplicity and minimal time requirements compared to the other scales.

Acenocoumarol-Induced Diffuse Alveolar Hemorrhage: A Case Report.

Diffuse alveolar hemorrhage (DAH) is bleeding into the alveolar spaces of the lung. DAH is often associated with systemic autoimmune diseases, coagulation disorders, drugs, inhaled toxins, or transplantation. This study describes a rare case of acenocoumarol-induced DAH, a pulmonary disorder, which has not been reported before. A 48-year-old male presented with a history of rheumatic heart disease with mitral stenosis with moderate mitral regurgitation status post mitral valve replacement. He was taking acenocoumarol but did not keep his prothrombin time-international normalized ratio (PT-INR) monitoring and came to the hospital with complaints of cough, hemoptysis, and breathlessness. Chest x-ray and high-resolution computed tomography (HRCT) thorax were done which revealed diffuse patchy opacities and pulmonary hemorrhage, respectively. After nine days of hospital stay with appropriate management with corticosteroids, antibiotics, and intravenous fluids, the patient was doing well.

The Transition of Children Living With Congenital Heart Disease to Adult Care.

The article explores the significance of the timely transition of a child living with congenital heart disease (CHD) to adult care and the role played by multidisciplinary care. Due to recent healthcare advances, more children with CHD survive to adulthood without surgical intervention. This survival is mainly due to the lesion being compatible with life and its management being done medically. However, further management requires meeting the child's needs and helping him transition to become a healthy, independent adult with almost equal life expectancy as his counterparts. The article reviews the comprehensive framework of transition through multidisciplinary care. Highlighting the necessity of training physicians to acquire expertise in the management of CHD is a foundational aspect of this review article. Introduction to transition requires assessment of the child's needs through all phases of life and informative counseling of both parents and child. It highlights the approach to educating patients and families with the knowledge to safeguard compliance. Multidisciplinary collaboration from various fields such as cardiology, pediatric physiatrist, nursing, and psychology has been stressed. Patients also need to cultivate skills in self-management and independence and be educated to comprehend their condition, including the potential health issues. This collaborative and multidisciplinary process necessitates the cooperation of patients, families, and the adult congenital heart disease (ACHD) team. Emphasis has been given to individualized counseling for girls to address their sexual health. The article also highlights the possible obstacles and how to tackle them to improve healthcare adherence. Timely transition and follow-up can be measured using various tools or through indices measuring the quality of life and average life expectancy. The global patterns of transition to ACHD care have also been emphasized, as well as the need for research studies to develop reliable indicators for assessing transition success.

Impact of Serum Amylase Level in the Outcome of Acute Organophosphorus Poisoning: 2-Year Cross-Sectional Study at Rural Teaching Hospital.

Introduction Prompt recognition and aggressive management of acute intoxication due to organophosphorus poisoning are essential to minimize the morbidity and mortality. The present study was undertaken to know the prognosis and outcome of organophosphorus poisoning patients with the estimation of low-cost enzymes like the serum amylase level in a population with financial constraints. Methods In this cross-sectional study, we had enrolled 100 cases that had a history of exposure to organophosphorus compounds, and the serum amylase level was measured in all the patients. We assessed the outcome of all the patients in the form of discharge, need of ventilators, intensive care unit stay, and death. Results The mean serum amylase level in discharge patients was 335.40 ± 192.45, and in the patients who died it was 843.37 ± 22.60. It was significant to predict the outcome ( t -value 7.07, p -value 0.0001, statistically significant). Conclusion Serum amylase level shows significant correlation with clinical outcomes in organophosphorus poisoning.

A Case Report of Hemophagocytic Lymphohistiocytosis (HLH) - An Unusual Complication of Dengue Infection.

Hemophagocytic lymphohistiocytosis (HLH) is an autoimmune phenomenon characterized by reactive hyperactivity of cytotoxic T cells and histiocytes, leading to hypercytokinemic injury to cells and organ system, which leads to multiorgan dysfunction and ultimate failure. Epstein-Barr virus (EBV) is most commonly associated with secondary HLH with high mortality, but increasing evidence suggests the association of the dengue virus. When associated with dengue infection, it carries a grave prognosis and correlates with the disease severity. Furthermore, it overlaps with dengue sepsis, so it can often be misdiagnosed as sepsis. Typically the patients have hyperferritinemia, hypertriglyceridemia, transaminitis, and marrow features suggestive of hemophagocytosis. The treatment is usually systemic corticosteroids, intravenous immunoglobulin, and chemotherapy with etoposide. We present a case of a 25-year-old male patient who had a dengue infection and further developed HLH with pulmonary infiltrates. Clinical suspicion alerted us to look for other evidence of HLH on the fourth day of admission, and appropriate investigations were done. Diagnosis of HLH was confirmed by HLH-2004, HScore criteria, and bone marrow aspirate examination. Treatment was given in the form of corticosteroids and chemotherapy along with other supportive measures. The patient responded to the line of management.

Acute Myocardial Infarction with Left Ventricular Failure as an Initial Presentation of Takayasu's Arteritis.

Takayasu's Arteritis (TA) is an uncommon chronic inflammatory and stenotic disease of medium and large-sized arteries characterized by a strong predilection for the aortic arch and its major branches. We report a rare manifestation of TA in a 16-year-old female with no previous history of heart disease who presented with heart failure. She was found to have hypertension and discrepancies of pulses in upper and lower limbs. She developed ST elevated anterior wall myocardial infarction (MI) during hospitalization. Her aortography revealed narrowing of descending thoracic, upper abdominal and infrarenal aorta with significant stenosis of both renal arteries. She was diagnosed as a case of TA on the basis of her clinical profile and arteriography. Her coronary angiography did not reveal any stenosis or occlusion or aneurysm in coronary arteries or at coronary ostia which is in contrast to patients of TA with MI reported in the literature who had focal or diffuse stenosis or aneurysm in the coronaries.

Symmetrical peripheral gangrene associated with peripartum cardiomyopathy.

Symmetrical peripheral gangrene (SPG) is a rare clinical entity. It was first described in late 19(th) century and since then has been reported with array of medical conditions mainly those complicated with shock, sepsis, and disseminated intravascular coagulation (DIC). Here in, we describe a parturient with peripartum cardiomyopathy (PPCM) and SPG. Clinicians should be aware of this entity as early recognition can help in reducing morbidity and mortality.
