Hyperacute Liver Failure with Multi-organ Dysfunction Syndrome (MODS) by Leptospirosis: A Case Report

Introduction: Leptospirosis may have multi-organ involvement in its severe form with potentially life-threatening consequences. However, acute fulminant hepatic failure is very uncommonly reported. A case study is presented here with fulminant hepatic failure and a diagnostic dilemma for etiology. Case history: A 40-year-old man with no significant medical history presented with fever, muscle pain, weakness, and pain in the upper abdomen. On clinical work, he has developed multi-organ hepatic, respiratory, and renal failure. A timely workup was done, but due to the rapid progression of the disease, the patient succumbed to the disease in the intensive care unit by the time his report for positive leptospirosis test arrived. Conclusion: Leptospirosis must be considered as an important differential diagnosis of acute liver failure patients. An early suspicion for leptospirosis in patients with fulminant hepatic failure and multi-organ failure in India particularly in the rainy season is warranted owing to its high mortality rate.

A semi-supervised network-based tissue-aware contrast enhancement method for CT images / 南方医科大学学报

OBJECTIVE@#To propose a tissue- aware contrast enhancement network (T- ACEnet) for CT image enhancement and validate its accuracy in CT image organ segmentation tasks.@*METHODS@#The original CT images were mapped to generate low dynamic grayscale images with lung and soft tissue window contrasts, and the supervised sub-network learned to recognize the optimal window width and level setting of the lung and abdominal soft tissues via the lung mask. The self-supervised sub-network then used the extreme value suppression loss function to preserve more organ edge structure information. The images generated by the T-ACEnet were fed into the segmentation network to segment multiple abdominal organs.@*RESULTS@#The images obtained by T-ACEnet were capable of providing more window setting information in a single image, which allowed the physicians to conduct preliminary screening of the lesions. Compared with the suboptimal methods, T-ACE images achieved improvements by 0.51, 0.26, 0.10, and 14.14 in SSIM, QABF, VIFF, and PSNR metrics, respectively, with a reduced MSE by an order of magnitude. When T-ACE images were used as input for segmentation networks, the organ segmentation accuracy could be effectively improved without changing the model as compared with the original CT images. All the 5 segmentation quantitative indices were improved, with the maximum improvement of 4.16%.@*CONCLUSION@#The T-ACEnet can perceptually improve the contrast of organ tissues and provide more comprehensive and continuous diagnostic information, and the T-ACE images generated using this method can significantly improve the performance of organ segmentation tasks.

Oxidative phosphorylation in septic organ injury / 国际儿科学杂志

Sepsis is a systemic inflammatory response syndrome caused by pathogenic microorganisms that infect the host.If treated improperly, it can progress to severe sepsis or even septic shock.As such, it′s one of the main reasons for the death of children in PICU.The inflammatory response of sepsis exerts great influence on a series of basic physiological functions of cells, including the oxidative phosphorylation of the mitochondria.Oxidative phosphorylation is a process during which oxygen is reduced to generate high-energy phosphate bonds in the form of adenosine triphosphate(ATP), which supplies energy for cells and produces a series of functional by-products.During sepsis, the process of oxidative phosphorylation in mitochondria undergoes a series of complex alterations, which in turn can further promote the development of septic organ injury.The present review aims to clarify the relationship between changes in oxidative phosphorylation and the impairment of various organs in sepsis.

SUMMARY Septic Septic shock with multi organ dysfunction is associated with a mortality above 50%. We present here the case of a young male patient who presented with septic shock and multi organ dysfunctions secondary to methicillinsusceptible Staphylococcus aureus from a skin and soft tissue infection presenting with alveolar-nodular pulmonary lesions, purulent pericarditis and septic embolic lesions on the skin, eyes and kidneys. The patient was admitted to the ICU receiving antibiotic coverage with oxacillin and vancomycin, subtotal pericardiectomy and pleural drainage, and was discharged clinically stable. We present this case to draw attention to the severity of S. aureus bacteremia to initiate prompt aggressive therapeutic measures to ameliorate associated morbidity and mortality.

Spectrum of microbial infection in an Intensive Care Unit: a single centre tertiary care experience in Southern Indian state of Karnataka

Background: There is an increased incidence of hospital acquired infection, especially in ICU setting, the most common being ICU acquired pneumonia which increases the morbidity, mortality, prolongs hospital stay and consuming more resources. Microbial etiology of intensive care unit (ICU)-acquired pneumonia (ICUAP) determines antibiotic treatment and outcomes which vary from centre to centre. Hence, a study of risk factors, clinical profile of patient, microorganisms and their resistance patterns to antibiotics are important for the diagnosis, prognosis of patient with ICU acquired pneumonia and also in the prevention of the same.Methods: Patients with ICUAP confirmed microbiologically were prospectively compared according to identification of 1 (monomicrobial) or more (polymicrobial) potentially pathogenic microorganism. Patients without microbiological confirmation were excluded from the study. We assessed clinical characteristics, microbiology and outcome variables.Results: In the present study 60 patients with ICU Pneumonia were included out of which 50 (83%) had mono-microbial infection. Most common organism isolated in mono microbial infection was Klebsiella species (26%), followed by Acinetobacter species (25%), out of which 20 percent was multidrug resistant. Multi-drug resistance was similarly frequent in both groups. Outcome variables like initial response to the empiric treatment, length of stay and mortality were similar in both monomicrobial and polymicrobial pneumonia. Mortality rates were higher with higher pneumonia scores (p value <0.002) and with multi organ dysfunction (p <0.008) irrespective of mono microbial or poly microbial infection.Conclusions: In this study mono microbial infection was more than polymicrobial, the most common organism being Kliebsiella species followed by Acinetobacter species. When empiric treatment is frequently appropriate, mortality rates were higher with higher pneumonia scores and MODS. In our study polymicrobial aetiology did not influence the outcome of ICUAP.

Multiple Organ Echinococcosis:Report of One Case and Literature Review / 中国医学科学院学报

A patient with multiple-organ echinococcosis suffered from liver echinococcosis,lung echinococcosis,and pelvic echinococcosis successively in the past three decades.From the first operation at 19 years-old,she underwent operations several times due to the recurrence of multiple organ involvement.Echinococcosis is a zoonotic disease.Although the liver usually is the primary site,the disease can also invade many other organs.Diagnosis is typically based on disease history and imaging findings.Thorough removal of the lesions during the first operation is particularly important.Comprehensive evaluations and multi-disciplinary team are helpful in the treatment of patients with multiple organ invasion.

Assessment of Predictors for Severity in Scrub Typhus-A Case-Control Study

Objective: Scrub typhus is a rickettsial febrile condition caused by bacteria called Orientia tsusugamushi. It spreads to people through bites of infected larval mites. The objective of this study was to predict the severity of scrub typhus. Methods: A case-control study was done at Kasturba Medical College Hospital (2012-2015) retrospectively on patients admitted with scrub typhus. Patient demographics, lab parameters, investigations and treatment courses were noted. Subjects were divided into two groups, non-severe and severe group. Patient clinical details and laboratory parameters were compared in both the groups. The lab parameters associated with the severity of disease and mortality were also analyzed. A total of 210 patients out of which 140 controls (non-severe group) and 70 were cases (severe group). Results: The overall mortality due to scrub typhus infection was 14.3%. Eschar was present in 21.4% of the patients. Among the cases, the common symptoms were cough, chest pain, abdominal pain and distension, pedal edema and facial puffiness. Lymphadenopathy was observed with non-severe cases of scrub typhus and was statistically significant whereas, icterus, maculopapular rash, and hepatomegaly were associated with severe scrub typhus infection. Hemoglobin, platelet count and serum albumin were considerably lower in patients who died, whereas AST, aPTT, serum urea and creatinine were higher in them. Conclusion: Lower levels of hemoglobin, platelet count, serum albumin and higher levels of total leucocyte count, hepatic transaminases and serum creatinine correlated with severity. Doctors need to be watchful for such lab parameters and act quickly.

Towards safe motherhood to - are we moving in the right direction?: experience from an urban health facility in South India

Background: This study was designed to evaluate the institutional Maternal Mortality Ratio (iMMR) in our institution, a tertiary private medical college hospital and to suggest recommendations and possible interventions to reduce it.Methods: This retrospective descriptive study was conducted by reviewing the hospital records over a period of ten years from January 2009-December 2018. The case records were reviewed for maternal demographic characteristics and complications.Results: The total number of deaths during the study period was 21, giving an iMMR of 85.268 per 100000 live births. Most of the maternal deaths (>80%) occurred postpartum. Obstetric causes contributed to 57% of the deaths with hypertension and hemorrhage topping the list. Other causes were sepsis and non obstetric causes including one case of maternal suicide. 52.38% of the women died more than 48 hours after admission to the hospital, while 28.57% succumbed in less than six hours. Secondary complications noted were ICU admission, extended intubation, massive transfusion, operative intervention and multi organ dysfunction.Conclusions: The classical triad of Hypertension, Hemorrhage and Sepsis continues to be the major determinant of maternal mortality and are potentially preventable by promoting universal access to quality health care, strengthening of health services and ensuring accountability.

Analytical study of mortality in Intensive Care Unit

Background: Intensive care Unit is the one place where we come across various medical critical cases and high number of deaths is also recorded here. In spite of so many deaths occurring at this unit, cause of death is poorly reported. We studied the different causes for deaths in ICU which includes single and multiple factors for cause of death.Methods: A retrospective study performed between January 2017 to January 2018 at Rajiv Gandhi Institute of Medical sciences, Kadapa, Ongole, A.P. This study includes 260 deaths among patients admitted in ICU of our institute during this duration. We gathered data at various levels like clinical evaluation and investigations.Results: A total of 260 deaths were recorded during this study. Among these 215 (82.69%) are female and 45 (17.30%) are male. At the time of death 174 (66.92%) patients has single systemic cause 86 (33.06%) had more than one systemic cause. Cardiovascular death 50 (19.23%) is the most common cause of death among all in which CAD 28 (10.76%) are major portion and congestive cardiac failure 20 (7.6%) are the remaining portion of the cardiac deaths. Chronic kidney disease 37 (14.2%) is the next highest deaths recorded and cerebro vascular 35 (13.46%) deaths follows the next in line.Conclusions: Majority of ICU patients were present with at least one organ failure at the time of death. What we have concluded in this study is that there are more number of deaths with single systemic cause than multiple systemic causes

Background: The 2009 flu outbreak in humans, knownas "swine influenza" or H1N1 influenza A, refers toinfluenza A due to a new H1N1 strain called SwineOrigin Influenza Virus A (S-OIV). Global pandemicswith high mortality and morbidity occur when avirulent new viral strain emerges. Aim and Objectives:To study demography, clinical profile and outcome ofH1N1 influenza infection at a tertiary care teachinghospital. Material and Methods: This was aprospective observational study conducted at theteaching hospital during six month period. It was a timest bound study over a period of six months (from 1 Julyth 2018 to 30 December 2018). All suspects with throatswab/nasal swab positive for influenza H1N1 virus byReverse Transcriptase Polymerase Chain Reaction(RT-PCR) with age more than 15 years were includedin the present study. Data were analysed for mean,percentage, standard deviation and Chi square test forquantitative data by using Microsoft Excel spreadsheet. Results: A total 60 patients were admitted withconfirmed diagnosis of H1N1 infection. Out of the 21(35%) were males and 39 (65%) were females,predominated by female gender (p=0.001). The meanage in male (46.14 ± 20.058) was relatively morecompared to female gender (36.33 ± 11.50). The malegender had more co-morbidities and risk factorscompared to female patients (p=0.01) and wasstatistically significant. Out of total 21 male patients 7patients died because of bilateral pneumonia and AcuteRespiratory Distress Syndrome (ARDS) and MultiOrgan Dysfunction (MOD) with case fatality rate of33.33%. Out of total 39 female patients 5 patients diedwith case fatality rate of 12.82%. Conclusion: Thepresent study highlighted the disease burdenassociated with H1N1 infection. The advancing age,male gender, associated co-morbidities and delayedpresentation were the risk factors for mortality inpresent cohort study of H1N1 patients. The communityawareness, early case detection and timelymanagement can reduce the disease burden at large

A comparative study between APACHE II and Ranson scoring systems in predicting the severity of acute pancreatitis

Background: Acute pancreatitis is a common disease with wide clinical variation and its incidence is increasing. Acute pancreatitis may vary in severity, from mild self-limiting pancreatic inflammation to pancreatic necrosis with life-threatening sequelae. The severity of acute pancreatitis is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis. Aim of the study: To compare the efficacy of Ranson scoring with APACHE II scoring system in predicting the severity of acute pancreatitis. Materials and methods: The present study was a prospective study of 33 cases of Acute pancreatitis admitted in Rajiv Gandhi Government General Hospital, Chennai, during the study period of July 2014 to September 2014. 33 cases for the purpose of the study were selected on the basis of the nonprobability (purposive) sampling method. multiple clinical and laboratory variables of both Ranson and APACHE II scoring system and the final score of the patient from both the scoring systems are assessed to know their efficacy in predicting the severity of the disease (higher the score more severe the disease). Results: Overall, 8(24.2%) patients suffered from severe pancreatitis and 25(75.7%) had mild acute pancreatitis of which all 8 had severe attack as per APACHE II score (>8) and only 3 of these were considered severe by Ranson score (>3). The systemic complications were a multiorgan failure in 2(6.06%), respiratory 1(3.03%) and renal 1(3.03%) all seen in patients with the severe score as per APACHE II. Umarani Subramaniam, Ahila Muthuselvi, Kesavan. A comparative study between APACHE II and Ranson scoring systems in predicting the severity of acute pancreatitis. IAIM, 2019; 6(4): 55-59. Page 56 Conclusion: The early diagnosis and precise scoring of disease severity are important goals in the initial evaluation and management of pancreatitis. Pancreatitis not only must be differentiated from a myriad of other potential diagnoses, but patients must also be stratified to identify those with severe disease and to guide appropriate therapy.

Multi-task learning-based three-dimensional dose distribution prediction for multiple organs in a single model / 中华放射肿瘤学杂志

Objective To establish a three-dimensional (3D) dose prediction model,which can predict multiple organs simultaneously in a single model and automatically learn the effect of the geometric anatomical structure on dose distribution.Methods Clinical radiotherapy plans of patients diagnosed with the same type of tumors were collected and retrospectively analyzed.For every plan,each organs at risk (OAR) voxel was regarded as the study sample and its deposited dose was considered as the dosimetric feature.A regularized multi-task learning method than could learn the relationship among different tasks was employed to establish the relationship matrix among tasks and the correlation between geometric structure and dose distribution among organs.In this experiment,the spinal cord,brainstem and bilateral parotids involved in the intensity-modulated radiotherapy (IMRT) plan of 15 nasopharyngeal cancer patients were utilized to establish the multi-organ prediction model.The relative percentage error between the predicted dose of voxel and the clinical planning dose was calculated to assess the feasibility of the model.Results Ten cases receiving IMRT plans were utilized as the training data,and the remaining five cases were used as the test data.The test results demonstrated a higher prediction accuracy and less data demand.And the average voxel dose errors among the spinal cord,brainstem and the left and right parotids were (2.01±0.02)％,(2.65± 0.02) ％,(2.45± 0.02) ％ and (2.55± 0.02) ％,respectively.Conclusion The proposed model can accurately predict the dose of multiple organs in a single model and avoid the establishment of multiple single-organ prediction models,laying a solid foundation for patient-specific plan quality control and knowledge-based treatment planning.

Evaluation of complications and factors associated with multi-organ dysfunction in malaria: a cross sectional study

Background: Prevalence of complications in malaria continues to grow even with reducing number of malaria cases. Complications associated with malaria can involve multiple organs. There is paucity of literature on factors associated with multi organ dysfunction in different types of malaria.Methods: Our aim was to study the clinical profile of complications in different types of malaria with specific focus on multi-organ dysfunction (MODS). In this cross-sectional study confirmed cases of malaria were enrolled.Results: Plasmodium vivax malaria was the predominant type seen in 74.1% cases. The overall prevalence of thrombocytopenia was 61.5%, hepatic dysfunction 58%, cerebral malaria 16.1%, Hypoglycemia 7.5%, bleeding 34.5%, acute respiratory distress syndrome (ARDS) 5.7% and acute kidney injury (AKI) 49.4%. Hypoglycemia was significantly higher in mixed malaria (0.025, p = 0.025). Hepatic dysfunction and hyperbilirubinemia were significantly higher in mixed malaria (p=0.001). Mortality was seen in mixed malaria (p = 0.007). Only those with mixed malaria died (13%). Patients with MODS had higher prevalence of rashes (p <0.0001) and cerebral malaria (p = 0.000). Serum levels of urea, creatinine, Bilirubin, Serum glutamic oxaloacetic transaminase (SGOT) and Serum glutamic pyruvic transaminase (SGPT) were significantly higher in patients with MODS (p<0.0001 for all variables). On evaluating factors associated with multi-organ dysfunction presence of cerebral malaria [OR: 6.4 (95% CI): 2.4 to 17.4; p<0.0001], type of malaria (Vivax or Falciparum or both) [1.77 (1.03 to 3.03); p=0.0038], and hypoglycemia [4.4 (1.08 to 17.8); p=0.038] were statistically significant on multivariate analysis.Conclusions: The present study demonstrates the factors associated with multi organ dysfunction and its impact on clinical outcome in different types of malaria.

Clinical spectrum and outcome of paraquat poisoning in a tertiary care teaching hospital

Background: Paraquat is most common insecticide compound used for suicidal consumption in rural part of the Karnataka next to organo-phosphorous compound. It produces various local and systemic manifestations in the early course. It is very notorious to cause multi-organ dysfunction and mortality within 24 hours in severe amount of consumption. Lack of specific antidote and high-quality evidence based medicine makes the management of paraquat poisoning challenging. Hence, we took up the study to evaluate the clinical features, course and management option for the poisoning.Methods: It is an observational study conducted at HIMS, Hassan. History was collected from patient and bystanders. Clinical features, laboratory parameters were noted regularly and frequently. Patient’s complications were identified initially and treated accordingly. All the data collected were tabulated and statistically analysed.Results: Out of 110 patients, 72 were females and 38 were males; most of them were in the age group of 30-40 years. Mild poisoning was noted in 30, moderate in 56 and 24 patients were severe. Most common symptom was nausea and signs were oral cavity ulcers followed by tachycardia and tachypnoea. The overall mortality was 72%, 18% were recovered fully and 10% patients left against medical advice.Conclusions: Since there is a lack of antidote management of paraquat is challenging. Early gastric lavage, aggressive fluids, IV methyl prednisolone and N-Acetyl-Cysteine is beneficial.

Mitochondrial Dysfunction and Immune Cell Metabolism in Sepsis / 감염과화학요법

Sepsis is a life threatening condition mediated by systemic infection, but also triggered by hemorrhage and trauma. These are significant causes of organ injury implicated in morbidity and mortality, as well as post-sepsis complications associated with dysfunction of innate and adaptive immunity. The role of cellular bioenergetics and loss of metabolic plasticity of immune cells is increasingly emerging in the pathogenesis of sepsis. This review describes mitochondrial biology and metabolic alterations of immune cells due to sepsis, as well as indicates plausible therapeutic opportunities.

Combined Heart and Liver Transplantation: The Asan Medical Center Experience / 대한이식학회지

Combined heart-liver transplantation (CHLT) is an increasingly accepted treatment for select patients with advanced heart and liver disease. However, CHLT are infrequently performed, despite growing optimism about their effectiveness. Here, we report Asan Medical Center experience with CHLT in three patients presenting with advanced heart and liver failure. One patient died of brain swelling because of intractable hyperammonemia on postoperative day 9. The two other patients were still alive at 53 and 9 months postsurgery. None of these patients required readmission for cardiac or hepatic graft dysfunction and no rejection episodes were detected on routine cardiac biopsies. This is the first report of CHLT cases from Korea.
