The impact of aspirin use on outcomes in patients with inflammatory bowel disease: Insights from a national database.

BACKGROUND: Inflammatory bowel disease (IBD) is an inflammatory disorder that can increase the risk of mortality. Aspirin is an anti-inflammatory drug used for primary prevention of cardiovascular events. A single center analysis previously reported that aspirin use did not impact major outcomes in IBD. In this study, we aim to assess the impact of aspirin use on mortality and other outcomes in patients with IBD using national data. METHODS: National inpatient sample (NIS) 2016-2020 was used to identify adult patients with IBD. Data were collected on patient demographics, hospital characteristics, and comorbidities. The outcomes studied were in-hospital mortality, sepsis, shock, Intensive Care Unit (ICU) admission, and need for surgery. Multivariate logistic regression analysis was performed. RESULTS: A total of 1,524,820 IBD hospitalizations were included. Of these, 137,430 (9%) were long-term aspirin users. The majority of the patients in the aspirin group were aged > 65 years (34.11%), female (56.37%), White (78.83%) and had Medicare insurance (36.77%). Aspirin users had a lower incidence of in-hospital mortality (1.6% vs 1.4%, P = 0.06), sepsis (2.5% vs 2.9%, P < 0.001), shock (2.9% vs 3.4%, P < 0.001), ICU admission (2.6% vs 2.9%, P < 0.001), need for surgery (2.1% vs 4.2%, P < 0.001). After adjusting for confounders, aspirin was associated with a reduction in mortality (adjusted odds ratio: 0.49, 95%CI 0.45-0.55, P < 0.001). CONCLUSION: Our study reports that aspirin use among patients with IBD was associated with a lower risk of death, sepsis, and shock. Aspirin use may have a protective effect in patients with IBD. Further studies are needed to confirm these results.

Mapping the stability of febrile illness hotspots in Punjab from 2012 to 2019- a spatial clustering and regression analysis.

INTRODUCTION: Febrile illnesses (FI) represent a typical spectrum of diseases in low-resource settings, either in isolation or with other common symptoms. They contribute substantially to morbidity and mortality in India. The primary objective was to study the burden of FI based on Integrated Disease Surveillance Programme (IDSP) data in Punjab, analyze geospatial and temporal trends and patterns, and identify the potential hotspots for effective intervention. METHODS: A retrospective ecological study used the district-level IDSP reports between 2012 and 2019. Diseases responsible for FI on a large scale, like Dengue, Chikungunya, Malaria (Plasmodium Falciparum, P. Vivax), Enteric fever, and Pyrexia of Unknown Origin (PUO), were included in the analysis. The digital map of Punjab was obtained from GitHub. Spatial autocorrelation and cluster analysis were done using Moran's I and Getis-Ord G* to determine hotspots of FI using the incidence and crude disease numbers reported under IDSP. Further, negative binomial regression was used to determine the association between Spatio-temporal and population variables per the census 2011. Stable hotspots were depicted using heat maps generated from district-wise yearly data. RESULTS: PUO was the highest reported FI. We observed a rising trend in the incidence of Dengue, Chikungunya, and Enteric fever, which depicted occasional spikes during the study period. FI expressed significant inter-district variations and clustering during the start of the study period, with more dispersion in the latter part of the study period. P.Vivax malaria depicted stable hotspots in southern districts of Punjab. In contrast, P. Falciparum malaria, Chikungunya, and PUO expressed no spatial patterns. Enteric Fever incidence was high in central and northeastern districts but depicted no stable spatial patterns. Certain districts were common incidence hotspots for multiple diseases. The number of cases in each district has shown over-dispersion for each disease and has little dependence on population, gender, or residence as per regression analysis. CONCLUSIONS: The study demonstrates that information obtained through IDSP can describe the spatial epidemiology of FI at crude spatial scales and drive concerted efforts against FI by identifying actionable points.

Malaria vector sibling species distribution in different endemic districts of Punjab, India.

BACKGROUND & OBJECTIVES: Malaria transmission in Punjab, India is mainly seasonal with variation in its endemicity that may be due to varying vector behaviour in different areas of the state, primarily attributed to the existence of sibling species complexes among the vector species. So far there is no report regarding the existence of malaria vectors sibling species in the state of Punjab, therefore, the present study was planned to investigate the status of sibling species of two main vectors of malaria viz. Anopheles culcifacies and Anopheles fluviatilis in different districts of Punjab. METHODS: Mosquito collections were made through hand catch in the morning hours. Malaria vector species An. culicifacies and An. fluviatilis were morphologically identified and man hour density was calculated. Both the vector species were subjected to molecular assays for sibling species identification through amplification of D3 domain of 28S ribosomal DNA by allele-specific PCR. RESULTS: Four sibling species of An. culicifacies, were identified viz. A, B, C and E. Species A was identified from Bhatinda district, species B, C and E from. S.A.S. Nagar and species C from Hoshiarpur. Two sibling species S and T of An. fluviatilis were identified from districts S.A.S. Nagar and Rupnagar. INTERPRETATION & CONCLUSION: Presence of four sibling species of An. culicifacies and two sibling species of An. fluviatilis in Punjab necessitates planning of longitudinal studies to ascertain their role in disease transmission so that appropriate interventions may be applied to achieve malaria elimination.

CRISPR/Cas tool designs for multiplex genome editing and its applications in developing biotic and abiotic stress-resistant crop plants.

Crop plants are prone to several yield-reducing biotic and abiotic stresses. The crop yield reductions due to these stresses need addressing to maintain an adequate balance between the increasing world population and food production to avoid food scarcities in the future. It is impossible to increase the area under food crops proportionately to meet the rising food demand. In such an adverse scenario overcoming the biotic and abiotic stresses through biotechnological interventions may serve as a boon to help meet the globe's food requirements. Under the current genomic era, the wide availability of genomic resources and genome editing technologies such as Transcription Activator-Like Effector Nucleases (TALENs), Zinc Finger Nucleases (ZFNs), and Clustered-Regularly Interspaced Palindromic Repeats/CRISPR-associated proteins (CRISPR/Cas) has widened the scope of overcoming these stresses for several food crops. These techniques have made gene editing more manageable and accessible with changes at the embryo level by adding or deleting DNA sequences of the target gene(s) from the genome. The CRISPR construct consists of a single guide RNA having complementarity with the nucleotide fragments of the target gene sequence, accompanied by a protospacer adjacent motif. The target sequence in the organism's genome is then cleaved by the Cas9 endonuclease for obtaining a desired trait of interest. The current review describes the components, mechanisms, and types of CRISPR/Cas techniques and how this technology has helped to functionally characterize genes associated with various biotic and abiotic stresses in a target organism. This review also summarizes the application of CRISPR/Cas technology targeting these stresses in crops through knocking down/out of associated genes.

Cost of National Vector Borne Disease Control Programme in North India.

Background & objectives: Despite significant resources being spent on National Vector Borne Disease Control Programme (NVBDCP), there are meagre published data on health system cost upon its implementation. Hence, the present study estimated the annual and unit cost of different services delivered under NVBDCP in North India. Methodology: Economic cost of implementing NVBDCP was estimated based on data collected from three North Indian States, i.e. Punjab, Haryana and Himachal Pradesh. Multistage stratified random sampling was used for selecting health facilities across each level [i.e. subcentres (SCs), Primary Health Centres (PHCs), community health centres (CHCs) and district malaria office (DMO)] from the selected States. Data on annual consumption of both capital and recurrent resources were assessed from each of the selected facilities following bottom-up costing approach. Capital items (equipment, vehicles and furniture) were annualized over average life span using a discount rate of 3 per cent. The mean annual cost of implementation of NVBDCP was estimated for each level along with unit cost. Results: The mean annual cost of implementing NVBDCP at the level of SC, PHC and CHC and DMO was ₹ 230,420 (199,523-264,901), 686,962 (482,637-886,313), 1.2 million (0.9-1.5 million) and 9.1 million (4.6-13.5 million), respectively. Per capita cost for the provision of complete package of services under NVBDCP was ₹ 45 (37-54), 48 (29-73), 10 (6-14) and 47 (31-62) at the level of SC, PHC, CHC and DMO level, respectively. The per capita cost was higher in Himachal Pradesh (HP) at SC [₹ 69 (52-85)] and CHC [₹ 20.8 (20.7-20.8)] level and in Punjab at PHC level [₹ 89 (49-132)] as compared to other States. Interpretation & conclusions: The evidence on cost of NVBDCP can be used to undertake future economic evaluations which could serve as a basis for allocating resources efficiently, policy development as well as future planning for scale up of services.

Vector and rodent surveillance for Orientia tsutsugamushi in north India.

BACKGROUND & OBJECTIVES: Scrub typhus or chigger borne typhus, caused by Orientia tsutsugamushi is an emerging vector-borne disease as large numbers of cases have been reported in various tropical countries. It is transmitted to humans through bites of infected chiggers (larval mites). The knowledge about the vector, its distribution, density and habitat are important so as to understand the epidemiology of scrub typhus in a given area. To control rickettsial infections, regular rodent-vector surveillance should be planned in areas where the disease transmission is occurring and it will also help to strengthen the existing entomological data related to the vector of scrub typhus in northern India. METHODS: In the present study, rodent-vector surveillance was planned for one whole year, covering both mite active and non-active seasons (October 2019-December 2020) in selected areas of Chandigarh and Punjab in north India. Rodent tissues and mites were also examined for the presence of O. tsutsugamushi by nested PCR for 56 kDa gene and real-time PCR for 47 kDa outer membrane protein gene. 18S gene PCR was performed for molecular identification of mites. RESULTS: In the surveillance, three types of ectoparasite, viz. mites, fleas and ticks were obtained in rodents. All mites found were of Laelapidae family. None of the pooled rodent tissue samples as well as mite samples were found positive for O. tsutsugamushi by nested PCR for rickettsial DNA. INTERPRETATION & CONCLUSION: In the present study, we did not get any evidence of carriage of O. tsutsugamushi in either mites or rodents collected and sampled in selected regions in Chandigarh and Punjab. We need to strengthen the entomological surveillance over a broader region and increase the frequency of trapping rodents to increase clarity on vector-reservoir dynamics in this geographical region.

Foodborne illness outbreak linked to a rural community kitchen in a rural area of Patiala District, Punjab, India, 2018.

BACKGROUND: In December 2018, an acute gastroenteritis outbreak was reported from Faridpur-Gujjran village, Patiala district, Punjab, India. OBJECTIVE: The objective of this study was to describe the epidemiology and risk factors of the outbreak and recommend prevention measures. METHODS: We conducted a descriptive study and a retrospective cohort study in the village. We defined a case as vomiting or ≥3 loose feces in 24 h plus abdominal pain and/or fever in a resident of the village during December 23-28, 2018. To find cases, we conducted a house-to-house survey; to identify risk factors, we conducted a retrospective cohort study. Fecal specimens were tested for enteric pathogens; water samples were tested for fecal contamination. We also interviewed food handlers. We compared attack rates by level of exposure. From the cohort study, we calculated risk ratios with 95% confidence intervals. RESULTS: From the 261 residents of the village, we identified 116 cases (attack rate 44%) and no deaths. The median age of affected persons was 27.5 years (range 0.5-80 years). The illness was associated with eating in a community kitchen of a temple during December 23-24, 2018. Eating mixed vegetables was associated with illness. We found no pathogens in fecal specimens. All three water samples showed coliform contamination. Cooked food had been left at room temperature before serving. CONCLUSION: Improper storage practices might have led to microbial proliferation of the food served. Our findings will help guide the enforcement of food safety policies for community kitchens.

Functional analysis of iron-sulfur cluster biogenesis (SUF pathway) from Plasmodium vivax clinical isolates.

Iron-sulfur (Fe-S) clusters are critical metallo-cofactors required for cell function. Assembly of these cofactors is a carefully controlled process in cells to avoid toxicity from free iron and sulfide. In Plasmodium, two pathways for these Fe-S cluster biogenesis have been reported; ISC pathway in the mitochondria and SUF pathway functional in the apicoplast. Amongst these, SUF pathway is reported essential for the apicoplast maintenance and parasite survival. Many of its components have been studied from P. falciparum and P. berghei in recent years, still few queries remain to be addressed; one of them being the assembly and transfer of Fe-S clusters. In this study, using P. vivax clinical isolates, we have shown the in vitro interaction of SUF pathway proteins SufS and SufE responsible for sulfur mobilization in the apicoplast. The sulfur mobilized by the SufSE complex assembles on the scaffold protein PvSufA along with iron provided by the external source. Here, we demonstrate in vitro transfer of these labile Fe-S clusters from the scaffold protein on to an apo-protein, PvIspG (a protein involved in penultimate step of Isoprenoids biosynthesis pathway) in order to provide an insight into the interaction of different components for the biosynthesis and transfer of Fe-S clusters. Our analysis indicate that inspite of the presence of variations in pathway proteins, the overall pathway remains well conserved in the clinical isolates when compared to that reported in lab strains.

Prevalence of submicroscopic malaria in low transmission state of Punjab: A potential threat to malaria elimination.

BACKGROUND & OBJECTIVES: Submicroscopic malaria infections with low parasite density serve as a silent reservoir for maintaining residual transmission in the population. These infections should be identified and targeted to be eliminated for sustained malaria control. The conventional methods of diagnosis such as light microscopy and rapid diagnostic kits often fail to detect low density infections. Therefore, the more sensitive molecular techniques should be employed to detect low density infections. The objectives of the study was to explore the prevalence of sub-microscopic infections in low transmission areas of Punjab using highly sensitive molecular tool. METHODS: A total of 1114 finger prick blood samples were collected through active surveillance and tested for malaria diagnosis using light microscopy, RDT and PCR. Nested PCR amplification was performed using a pair of Plasmodium genus-specific primers from the 18S rRNA small subunit gene (18S rRNA). The amplified PCR products were analysed using a 2% agarose gel, stained with ethidium bromide and observed under transilluminator. RESULTS: Test positive rate (TPR) by microscopy, RDT and PCR was 4.4, 3.95 and 5.75%, respectively. Microscopy and RDT failed to detect mixed infections whereas 0.26% cases were found to be mixed infection in PCR. Compared to LM and RDT, PCR has detected 1.3% additional positive cases. However, of the total positive cases detected by PCR, 23.4% infections were found to be submicroscopic, which could not be detected by conventional methods of diagnosis. INTERPRETATION & CONCLUSIONS: The molecular study revealed the existence of submicroscopic malaria cases in the study population which would have remained undetected by conventional methods of diagnosis. This is particularly important because Punjab state is in malaria elimination phase and targeted to achieve elimination in 2021. However, such undetected parasite positive cases may pose bigger problem any time due to continued transmission. Therefore, application of more sensitive diagnostic tools like PCR and LAMP with conventional methods may be much more useful in case detection particularly in low transmission settings for malaria elimination.

Growth arrest in the ribosomopathy, Bowen-Conradi syndrome, is due to dramatically reduced cell proliferation and a defect in mitotic progression.

Bowen-Conradi syndrome (BCS) is a ribosomopathy characterized by severe developmental delay and growth failure that typically leads to death by one year of age. It is caused by a c.257A>G, p.D86G substitution in the ribosomal biogenesis protein, Essential for Mitotic Growth 1 (EMG1). We generated a knock-in of the D86G substitution in mice to characterize the effects of EMG1 deficiency, particularly in the brain, where EMG1 expression is high. Embryos homozygous for the mutation in Emg1 were small for gestational age with neural tube defects, and died between embryonic days 8.5 and 12.5. These embryos exhibited dramatically reduced cell proliferation, which we also detected in autopsy brain tissue and bone marrow of BCS patients, consistent with a requirement for high levels of EMG1 in tissues with rapid cell proliferation. In fibroblasts derived from the BCS mouse embryos, we detected a high proportion of binucleated cells, indicating that a mitotic defect underlies the growth arrest in BCS. These studies add to growing evidence of a link between ribosome biogenesis, mitotic progression, and brain development that is currently unexplored.

Radioembolization following Liver Resection: Safety and Dosing Considerations.

PURPOSE: To evaluate the impact of previous liver resection on the safety of resin microsphere radioembolization (RE). MATERIALS AND METHODS: A single-center retrospective review was performed of 22 patients who underwent resin microsphere RE after liver resection during the period 2009-2014. Prescribed patient dose using the body surface area (BSA) model and a theoretical dose calculated from the actual liver volume on imaging were recorded. Patient and treatment characteristics were analyzed for factors that contributed to toxicity. RESULTS: In 13 patients, 20 grade 1-3 toxicities were identified. No differences in toxicity were seen based on extent of prior hepatic resection or whether whole-liver treatments were performed (P = .2). The measured liver volume based on cross-sectional imaging correlated poorly with the expected liver volume based on BSA (r = 0.43). After adjusting for the patients' measured liver volume on cross-sectional imaging, five patients were determined to be relatively overdosed and seven patients were determined to be relatively underdosed by the BSA method. Despite these differences, no association was found with patient toxicities and either an overestimation or an underestimation of liver volume (P = .4). CONCLUSION: Previous hepatic resection does not adversely alter the safety profile of yttrium-90 RE. BSA poorly predicts expected liver volume in this population. However, standard BSA-based dosing and whole-liver remnant treatments do not increase hepatotoxicity.

Colorectal liver metastases: making the unresectable resectable using irreversible electroporation for microscopic positive margins - a case report.

BACKGROUND: Irreversible electroporation (IRE) is a non-thermal injury tissue ablation technique that uses electrical pulses to cause cell death. IRE damages the endothelial cells of blood vessels; however these cells re-grow, and thus IRE does not result in permanent damage to blood vessels. We report the novel use of IRE for ablation of microscopically positive margins after resection of colorectal liver metastases (CRLM) impinging on hepatic veins. CASE PRESENTATION: A 68-year-old female was found to have colon cancer and synchronous bilateral unresectable liver metastases. Chemotherapy with FOLFOX and cetuximab was initiated, with subsequent conversion to resectability of the CRLM. The patient underwent colectomy followed by right liver posterior sectionectomy with wedge resection of segment 5. Resection of tumor impinging on the left and middle hepatic veins would have required left hepatectomy, with insufficient remnant liver volume. The CRLM were meticulously dissected off the hepatic veins leaving a microscopically positive margin, and IRE was then used for margin ablation, leaving intact hepatic veins and venous blood flow. The patient is alive and without recurrent disease now 30 months after resection. Herein we review the IRE technology and its use in ablation of liver metastases. CONCLUSIONS: Use of IRE margin ablation for microscopically-positive CRLM resection may lead to long-term patient survival; further prospective randomized trials are needed to confirm this finding.

Molecular detection of dengue and chikungunya viruses in surveillance of wild-caught Aedes mosquitoes in Punjab, North India.

BACKGROUND: Dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses are transmitted mainly by Aedes mosquitoes and are responsible for a significant global healthcare burden. The current study aimed to detect arboviruses in the Aedes mosquitoes in close proximity of patients during the transmission season. METHODS: Both immature and adult mosquitoes were collected from in and around the patients' houses. Mosquito pools were homogenized and extracted RNA was subjected to reverse transcription polymerase chain reaction for arboviral detection. Transovarian transmission (TOT) was assessed by screening F0 adults. Mosquito positivity was correlated with the aetiological agents identified in patients. RESULTS: Of 46 pools, 19 consisted of wild Aedes, with arboviral positivity in 53% (10/19) of pools. Among wild A. aegypti pools, positivity of DENV mono-infection, CHIKV mono-infection and DENV+CHIKV co-infection was noted in four, two and three pools, respectively. One wild pool of Aedes albopictus was positive for DENV-1. Similarly, A. aegypti F0 (adult Aedes developed from immatures) pools showed 59.2% (16/27) positivity for arboviruses. F0 Aedes showed positivity in three, six and seven pools for DENV-2, CHIKV and DENV+CHIKV, respectively, suggestive of TOT. DENV serotypes and CHIKV from 24 patients' serum samples were matched with strains isolated from Aedes and correlation was observed in four instances. CONCLUSIONS: The study detected DENV and CHIKV from wild-caught Aedes and found evidence of DENV and CHIKV TOT in F0 adults.

Post-campaign coverage evaluation of a measles and rubella supplementary immunization activity in five districts in India, 2019-2020.

BACKGROUND: In alignment with the Measles and Rubella (MR) Strategic Elimination plan, India conducted a mass measles and rubella vaccination campaign across the country between 2017 and 2020 to provide a dose of MR containing vaccine to all children aged 9 months to 15 years. We estimated campaign vaccination coverage in five districts in India and assessed campaign awareness and factors associated with vaccination during the campaign to better understand reasons for not receiving the dose. METHODS AND FINDINGS: Community-based cross-sectional serosurveys were conducted in five districts of India among children aged 9 months to 15 years after the vaccination campaign. Campaign coverage was estimated based on home-based immunization record or caregiver recall. Campaign coverage was stratified by child- and household-level risk factors and descriptive analyses were performed to assess reasons for not receiving the campaign dose. Three thousand three hundred and fifty-seven children aged 9 months to 15 years at the time of the campaign were enrolled. Campaign coverage among children aged 9 months to 5 years documented or by recall ranged from 74.2% in Kanpur Nagar District to 90.4% in Dibrugarh District, Assam. Similar coverage was observed for older children. Caregiver awareness of the campaign varied from 88.3% in Hoshiarpur District, Punjab to 97.6% in Dibrugarh District, Assam, although 8% of children whose caregivers were aware of the campaign were not vaccinated during the campaign. Failure to receive the campaign dose was associated with urban settings, low maternal education, and lack of school attendance although the associations varied by district. CONCLUSION: Awareness of the MR vaccination campaign was high; however, campaign coverage varied by district and did not reach the elimination target of 95% coverage in any of the districts studied. Areas with lower coverage among younger children must be prioritized by strengthening the routine immunization programme and implementing strategies to identify and reach under-vaccinated children.

Ectopic Liver Tissue Encountered Incidentally During a Laparoscopic Cholecystectomy: A Case Report.

A 60-year-old male patient who presented with right upper quadrant (RUQ) pain was diagnosed with acute cholecystitis after an ultrasound of the abdomen revealed multiple gallstones, gallbladder wall thickening, pericholecystic fluid, and a positive sonographic Murphy sign. The patient was admitted, administered IV fluids, antibiotics, and pain relief, and scheduled for laparoscopic cholecystectomy. During surgery, an incidental finding of ectopic liver tissue attached to the gallbladder was noted. Histopathology confirmed the presence of chronic cholecystitis and multifaceted cholesterol stones. Normal liver tissue was noted in the ectopic mass. Ectopic liver tissue is defined as liver tissue located outside the main liver parenchyma and is usually asymptomatic. They are usually detected at the time of autopsies, incidentally during surgeries, or during imaging done for other etiologies. They can occur at various sites in the body. Ectopic liver tissue can cause potential complications such as hepatocellular carcinoma and torsion, and in the event that they are incidentally detected, it is advised to remove them. The case report highlights the importance of dealing with incidental findings during laparoscopic cholecystectomy and creating awareness about it.

Acute Delirium Post-inguinal Hernia Mesh Repair in a 40-Year-Old Male: An Unusual Case of Cystocerebral Syndrome.

Acute urinary retention is a known complication of inguinal hernia repair. However, the development of severe agitation and delirium as a result of acute urinary retention following inguinal hernia repair is less commonly reported. Here, we present the case of a 40-year-old male with no relevant medical history who underwent open mesh hernia repair for an uncomplicated left-sided indirect inguinal hernia. Postoperatively, the patient became hypertensive, delirious, and violent. He was found to have urinary retention on a bladder scan. Urgent intervention with catheterization and bladder decompression resulted in the prompt resolution of the patient's symptoms. The patient regained his senses and did not remember the events that led to it. This case highlights the importance of recognizing and managing acute urinary retention to prevent the development of severe agitation and delirium following spinal anesthesia. Further research and awareness are necessary to better understand the underlying neurovisceral mechanisms and optimize preventive strategies.

Pericardial Cyst in Birt-Hogg-Dubé Syndrome: An Unexpected Discovery.

Birt-Hogg-Dubé syndrome (BHD) is a genetic disorder typically characterized by pulmonary cysts, cutaneous fibrofolliculomas, and renal tumors. We report a case of an 87-year-old male patient with a known diagnosis of BHD and a large pericardial cyst who presented to the emergency room with chest pain. BHD is classically associated with pulmonary cysts and not pericardial cysts. In this report, we highlight the potential of pericardial cysts to independently cause retrosternal pain resembling angina, while also mentioning that BHD too can cause chest pain through the rupture of a pulmonary cyst leading to spontaneous pneumothorax. In our case, coronary angiography revealed non-obstructive coronary arteries, so the cause of chest pain was attributed to myocardial infarction with non-obstructive coronary arteries (MINOCA). Atypical causes of chest pain should be considered, especially in patients with diagnosed genetic syndromes.

Hepatopulmonary Syndrome in a Patient With Autoimmune Hepatitis and Chronic Hepatitis C: A Case Report Highlighting Typical Echo Findings.

Hepatopulmonary syndrome (HPS) is a rare complication of liver disease characterized by intrapulmonary vascular dilatations leading to arterial hypoxemia. We present the case of a 59-year-old female with a past medical history of bilateral breast cancer status post mastectomy who presented with progressive dyspnea on exertion and fatigue. A comprehensive diagnostic workup was conducted to exclude other cardiac, pulmonary, and systemic etiologies. She was diagnosed with autoimmune hepatitis along with chronic hepatitis C. Echocardiography revealed characteristic findings of intrapulmonary shunting characteristic of HPS. The patient showed improvement in pulmonary symptoms and oxygenation status following the initiation of steroid therapy. Although corticosteroids are not the definitive treatment for HPS, they were considered a supportive measure in this case. However, it is important to note that liver transplantation remains the definitive treatment for HPS. This case underscores the importance of echocardiography and the potential role of supportive measures, like corticosteroids, in managing HPS-related symptoms, particularly in patients with autoimmune hepatitis, as a bridging therapy while awaiting liver transplantation.

Herpes Simplex Virus Meningoencephalitis Masquerading as Acute Stroke With Broca's Aphasia: A Case Report.

This case report presents a rare and unique instance of a 70-year-old morbidly obese female with type 2 diabetes mellitus and bilateral lymphedema, who presented with fever and expressive aphasia, initially suspected to be a stroke. A negative CT scan prompted the performance of an MRI, which revealed suggestive imaging findings of herpes encephalitis. Following the MRI, the patient experienced seizures and required intubation in the intensive care unit. Subsequently, a lumbar puncture was performed, confirming the diagnosis of herpes simplex virus (HSV) meningoencephalitis. Prompt initiation of acyclovir therapy led to an improvement in aphasia, ultimately allowing for extubation and transfer to the general ward. The rarity of this case lies in the unusual manifestation of Broca's aphasia caused by HSV, which is not typically associated with this neurological deficit. This report highlights the importance of considering herpes encephalitis as a potential etiology in patients presenting with atypical neurological symptoms, even in the absence of typical radiological findings. Early diagnosis and appropriate management with acyclovir are crucial in improving outcomes in such cases.
