The article presents a case study of a 6-year-old girl experiencing recurrent Kawasaki disease (KD) accompanied by Kawasaki disease shock syndrome (KDSS). Topics discussed include the challenges in diagnosing KDSS, the elevated inflammatory markers indicating severity, and the management strategies implemented, including the use of intravenous immunoglobulin (IVIG) and antiplatelet therapy.

Aim: This study was designed to investigate the association between Charlson Comorbidity Index (CCI) and in‐hospital mortality and other clinical outcomes among patients with hyperglycemic crises. Method: This retrospective cohort study was conducted using data from electric medical records. A total of 1668 diabetic patients with hyperglycemic crises from six tertiary hospitals met the inclusion criteria. CCI < 4 was defined as low CCI and CCI ≥ 4 was defined as high CCI. Propensity score matching (PSM) with the 1:1 nearest neighbour matching method and the caliper value of 0.02 was used to match the baseline characteristics of patients with high CCI and low CCI to reduce the confounding bias. In‐hospital mortality, ICU admission, hypoglycemia, hypokalemia, acute kidney injury, length of stay (LOS), and hospitalisation expense between low CCI and high CCI were compared and assessed. Univariate and multivariate regression were applied to estimate the impact of CCI on in‐hospital and other clinical outcomes. Outcome: One hundred twenty‐one hyperglycemic crisis (HC) patients died with a mortality rate of 7.3%. After PSM, compared with low CCI, patients with high CCI suffered higher in‐hospital mortality, ICU admission, LOS, and hospitalisation expenses. After multivariate regression, age (aOR: 1.12, 95% confidence interval [CI]: 1.06−1.18, p < 0.001), CCI(aOR: 4.42, 95% CI: 1.56−12.53, p = 0.005), uninsured (aOR: 22.32, 95% CI: 4.26−116.94, p < 0.001), shock (aOR: 10.57, 95% CI: 1.41−79.09, p = 0.022), mechanical ventilation (aOR: 75.29, 95% CI: 12.37−458.28, p < 0.001), and hypertension (aOR: 4.34, 95% CI: 1.37−13.82, p = 0.013) were independent risk factors of in‐hospital mortality of HC patients. Besides, high CCI was an independent risk factor for higher ICU Admission (aOR: 5.91, 95% CI: 2.31−15.08, p < 0.001), hypoglycemia (aOR: 2.19, 95% CI:1.01−4.08, p = 0.049), longer LOS (aOR: 1.23, 95% CI: 1.19−2.27, p = 0.021), and higher hospitalisation expense (aOR: 2089.97, 95% CI: 193.33−3988.61, p = 0.031) of HC patients. Conclusion: CCI is associated with in‐hospital mortality, ICU admission, hypoglycemia, LOS, and hospitalisation expense of HC patients. CCI could be an ideal indicator to identify, monitor, and manage chronic comorbidities among HC patients. [ABSTRACT FROM AUTHOR]

Background: Sheehan's syndrome is a rare condition, which is classically characterized by anterior pituitary hypofunction following postpartum shock or hemorrhage. While diabetes insipidus (DI) is not commonly associated with Sheehan's syndrome, we present a rare case of a multiparous female developing rapid-onset panhypopituitarism and DI following severe postpartum hemorrhage. Case presentation: A previously healthy 39-year-old woman, gravida 5, para 4, presented with hypovolemic shock after vaginal delivery, attributed to severe postpartum hemorrhage, necessitating emergent hysterectomy. Although her shock episodes resolved during hospitalization, she developed intermittent fever, later diagnosed as adrenal insufficiency. Administration of hydrocortisone effectively resolved the fever. However, she subsequently developed diabetes insipidus. Diagnosis of Sheehan's syndrome with central diabetes insipidus was confirmed through functional hormonal tests and MRI findings. Treatment consisted of hormone replacement therapy, with persistent panhypopituitarism noted during a ten-year follow-up period. Conclusions: Sheehan's syndrome is a rare complication of postpartum hemorrhage. Central diabetes insipidus should be suspected, although not commonly, while the patient presented polyuria and polydipsia. Besides, the potential necessity for long-term hormonal replacement therapy should be considered. [ABSTRACT FROM AUTHOR]

Background: Acute spontaneous bleeding from renal angiomyolipoma (AML) is one of the causes of Wunderlich syndrome, a rare and potentially fatal clinical condition. Clinical deterioration will occur if there is a delay in urgent management. There are several management options for renal angiomyolipoma rupture. However, until now little is known about the case of recanalization from post-coil embolization of renal angiomyolipoma. There is no guideline about embolization technique for the management of recurrent bleeding after embolization or coil recanalization of renal angiomyolipoma. Case presentation: A 55-year-old male has Wunderlich syndrome caused by recurrent bleeding of giant AML of the left renal due to coil recanalization compounded by a pseudoaneurysm and other bleeding site in bilateral giant renal angiomyolipoma which is showed by contrast-enhanced abdominal computed tomography scan. The patient underwent urgent transarterial embolization and some blood transfusion. Clinical improvement occurred and the patient discharged several days later. Conclusions: Embolization for spontaneous bleeding or rebleeding of renal pseudoaneurysms may become the first choice of treatment in bilateral multiple renal angiomyolipoma rather than other managements which are available to preserve renal function.

Background: Acute kidney injury (AKI) is a severe complication of acute diarrheal diseases; however, there is limited data on post-diarrheal AKI (PD-AKI) epidemiology and outcomes. This study aimed to investigate the clinicodemographic profile and outcomes of PD-AKI in our hospital. Materials and Methods: We retrospectively analyzed data from 93 patients admitted with PD-AKI during a diarrheal illness epidemic. Patients were stratified based on the Kidney Disease: Improving Global Outcomes (KDIGO) AKI stage and quick Sequential Organ Failure Assessment (qSOFA) score. Clinicodemographic data and outcomes were recorded and analyzed. Results: The mean age of the patients was 45.7 ± 11.9 years, with a majority being men (n = 55, 59%). All patients presented with watery diarrhea, 85% (n = 79) had vomiting, and 66% (n = 61) presented in shock. At presentation, 59% were oliguric, while 32% were anuric. KDIGO stage 3 AKI was observed in 71% (n = 66) of patients. Dialytic support was required in 29% (n = 27) of cases. The mortality rate was 6.5% (n = 6), mostly due to refractory shock, while the remaining patients recovered. Risk factor analysis demonstrated a higher qSOFA score, and peak serum creatinine levels were associated with an increased likelihood of requiring renal replacement therapy and delayed renal recovery. Conclusion: This study provides valuable insights into the clinicodemographic characteristics and outcomes of PD-AKI. The high prevalence of severe AKI emphasizes the importance of early recognition and appropriate management strategies for these patients. [ABSTRACT FROM AUTHOR]

Shwachman Diamond Syndrome (SDS) is a multi-system disease characterized by exocrine pancreatic insufficiency with malabsorption, infantile neutropenia and aplastic anemia. Life-threatening complications include progression to acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS), critical deep-tissue infections and asphyxiating thoracic dystrophy. In most patients, SDS results from biallelic pathogenic variants in the SBDS gene, different combinations of which contribute to heterogenous clinical presentations. Null variants are not well tolerated, supporting the theory that the loss of SBDS expression is likely lethal in both mice and humans. A novel complex genotype (SBDS:c.[242C>G;258+2T>C];[460-1G>A]/WFS1:c.[2327A>T];[1371G>T]) was detected in a family with recurrent neonatal deaths. A female neonate died three hours after birth with hemolytic anemia, and a male neonate with severe anemia, thrombocytopenia and neutropenia succumbed on day 40 after Staphylococcus epidermidis infection. A subsequent review of the literature focused on fatal complications, complex SBDS genotypes and/or unusual clinical presentations and disclosed rare cases, of which some had unexpected combinations of genetic and clinical findings. The impact of pathogenic variants and associated phenotypes is discussed in the context of data sharing towards expanding scientific expert networks, consolidating knowledge and advancing an understanding of novel underlying genotypes and complex phenotypes, facilitating informed clinical decisions and disease management.

Background: Analyses of extensive, nationally representative databases indicate a rising prevalence of venous thromboembolism (VTE) among critically ill children. However, the majority of studies on childhood VTE have primarily concentrated on Caucasian populations in the United States and European countries. There is a lack of epidemiological studies on VTE in Chinese children. Methods: We conducted a retrospective cohort study of data from the Pediatric Intensive Care (PIC) database. Data were obtained and extracted by using Structured Query Language (SQL) and the administrative platform pgAdmin4 for PostgreSQL. Bivariate analyses were conducted in which categorical variables were analyzed by a chi-square test and continuous variables were analyzed by a Student's t-test. Separate multivariable logistic regressions were employed to investigate the associations between VTE and sociodemographic factors as well as clinical factors. Results: Our study included 12,881 pediatric patients from the PIC database, spanning the years 2010 to 2018. The incidence rate of pediatric VTE was 0.19% (24/12,881). The venous thrombotic locations were deep venous thrombosis extremities (n = 18), superior vena cava (n = 1), cerebral sinovenous (n = 1), and other deep venous thrombosis (n = 4). Univariate analysis showed that age, weight, shock, sepsis, cancer and vasopressor receipt were statistically significant risk factors for pediatric VTE (all p ≤ 0.05). After multivariable logistic regression analysis, only shock (aOR: 6.77, 95%CI: 1.33–34.73, p = 0.019) and admission for sepsis (aOR: 6.09, 95%CI: 1.76–21.09, p = 0.004) were statistically significant associated with pediatric VTE. Conclusions: In conclusion, data obtained from the Pediatric Intensive Care (PIC) database revealed a prevalence of VTE in pediatric patients of 0.19%. The most common location for venous thrombi was deep venous thrombosis (DVT) in the extremities. We identified that shock and sepsis were statistically significant factors associated with pediatric VTE. [ABSTRACT FROM AUTHOR]

Pediatric liver transplantation is the main therapeutic modality for patients with liver cirrhosis secondary to biliary atresia. Unfortunately, approximately 22% will require a retransplantation. We present the case of a 15‑month‑old male patient diagnosed with biliary atresia, who received a liver transplant, which was complicated with hepatic artery thrombosis. For this reason, he received a retransplantation. Afterward, he had gastric varices and portal vein stenosis, which were resolved successfully by interventional radiology. Currently, liver with normal function, and adequate psychomotor development. It is very important to quickly identify and manage biliary atresia and to be aware of early and late complications of transplantation; once identified, it is necessary to perform the appropriate treatment for complications to avoid fatal outcomes.

Background. Hypertrophic cardiomyopathy (HCM) has different complications such as cardiac arrhythmia and sudden cardiac death (SCD). Insertion of an implantable cardioverter defibrillator (ICD) is recommended for HCM patients who are at high risk of SCD and malignant arrhythmias, despite having their own potential complications. Hypothesis. We aimed to investigate the prevalence of different complications of ICD insertion and the impact of the potential influential baseline characteristics in a one-year follow-up period. Methods. This was a retrospective study with a total of 71 HCM patients with ICD insertion. We evaluated the prevalence of different complications of ICD implantation and the impact of baseline characteristics on the occurrence of ICD complications using multivariate regression analysis in three 4-month periods. Results. In a one-year follow-up, 13 patients (18.3%) experienced at least one of the complications including pneumothorax, lead failure, ICD infection, inappropriate shocks, perforation, and upper limb deep vein thrombosis (DVT) with no mortality. Inappropriate shocks were reported as the most common (11.3%) complication during this period, with a gradual increase in the second (4.2%) and third (5.6%) follow-up sessions. Among all of the baseline characteristics that were investigated in this study, a positive history of hypertension was the only risk factor with significant impact on the occurrence of complications (P = 0.01). Conclusion. We demonstrated the occurrence of complications during a one-year follow-up as 18.3% in HCM patients with ICD insertion. A positive history of hypertension was the only baseline characteristic affecting the occurrence of complications, and inappropriate shocks were the most common complication. [ABSTRACT FROM AUTHOR]

Diabetic Ketoacidosis (DKA) is a serious complication of insulin deficiency. It is typically seen in children and young people with Type 1 Diabetes Mellitus, either at first presentation, or in established disease, for instance due to poor compliance, equipment failure, or concurrent illness. Insulin deficiency leads to hyperglycaemia causing osmotic fluid loss, dehydration and electrolyte derangement. Osmotic symptoms of polyuria and polydipsia due to hyperglycaemia may give way to oliguria or anuria as circulatory insufficiency develops. Unable to utilise glucose, cells default to alternative mechanisms of energy production resulting in the accumulation of ketone bodies. Kussmaul breathing may compensate partially for the worsening acidosis. Untreated, DKA results in progressively worsening acidosis, development of shock, coma and ultimately death. Clear guidelines for the management of DKA in children and young people exist once a diagnosis is made. However, evidence for these guidelines is limited and remains the subject of ongoing debate. Diligence is required to ensure that fluid and insulin is delivered appropriately, and to identify early the complications of both DKA and its treatment, such as cerebral oedema. In this article we review the current state of DKA management with key practice points. [ABSTRACT FROM AUTHOR]

Background: Despite significant loss of bicarbonate during acute diarrhea, pediatric data are scarce with acute diarrhea/severe dehydration (ADSD) and severe non-anion-gap metabolic acidemia (sNAGMA). We planned to study their clinical profile, critical care needs, and outcome. Patients: Children (1 month-12 years) with ADSD and sNAGMA (pH <7.2 and/or bicarbonate <15 mEq/L, and normal/mixed anion gap) admitted in Pediatric Emergency Department from January 2016 to December 2018 were enrolled. Children with pure high-anion-gap metabolic acidemia were excluded. Methods: Medical records were reviewed retrospectively. The primary outcome was time taken to resolve acidemia. Secondary outcomes were acute care area free days in 5 days (ACAFD5), and adverse outcome as composite of Pediatric Intensive Care Unit (PICU) admission and/or death. Results: Out of 929 diarrhea patients admitted for intravenous therapy, 121 (13%; median age, 4 months) had ADSD and sNAGMA. Median (IQR) pH was 7.11 (7.01-7.22); 21% patients had pH <7.00. Hyperchloremia (96%) and hypernatremia (45%) were common. About 12% patients each required inotropes and ventilation, while 58% had acute kidney injury (AKI). Median (IQR) time for resolution of acidemia among survivors was 24 (12, 24) hours. Thirty-two patients had adverse outcome. Higher grades of sNAGMA were associated with shock, AKI, coma, hypernatremia, hyperkalemia, adverse outcome, and lesser ACAFD5. Shock, ventilation, renal replacement therapy (RRT), and higher grades of sNAGMA were predictors of adverse outcome, with former two being independent predictors. Conclusions: Severe non-anion-gap metabolic acidemia in children with ADSD is associated with organ dysfunctions, dyselectrolytemias, and lesser ACAFDs. Resolution of acidemia took unacceptably longer time. Higher grades of sNAGMA were a predictor of adverse outcomes. Trials are suggested to assess the role of additional bicarbonate therapy.

Background: Work of breathing (WOB) and non-comorbidities factors in the respiratory system are the two probable findings in pediatric COVID-19 patients. However, the association of those factors with level of care was not well reported. Purpose: This study aimed to identify the relation between potential predictors including comorbidity, low nutritional fulfillment, infectious disease, shock, cough, O2 saturation reduction, abnormal blood gas analysis and sore throat with the level of care among pediatric COVID-19 patients. We also analyzed the synergistic correlation of non-comorbidities factors in the respiratory system and work of breathing to predict level of care in pediatric COVID-19 patients. Methods: A cross-sectional study was conducted in the six referral hospitals from July to September 2020 in four provinces in Indonesia. An observation checklist was used to collect data from the medical records of pediatric patients with COVID-19, including medical diagnosis, demographic, and clinical manifestation. This study included 423 participants aged from 0 to 18. The multivariate logistic regression was performed to test the adjusted odds ratios (AORs) with the 95% confidence intervals (CIs) of the association between WOB, non-comorbid respiratory, and level of care. Moreover, dummy variables (2x2) were made to analyze synergistic correlation of non-comorbid respiratory disease and WOB. The AOR with the 95% CIs was applied in the association between the complication of non-comorbid respiratory diseases and high work of breathing with level of care among pediatric patients with COVID-19. Results: Results showed that age, presence of comorbidity, nutritional fulfillment, infectious disease, shock, work of breathing, O2 saturation reduction, abnormal blood gas analysis, sore throat, and convulsive meningeal consciousness were significantly associated with the level of care (p<0.05). Pediatric patients with non-comorbid respiratory and increased work of breathing had a 15.59 times higher risk of requiring PICU care level (p<0.01). Meanwhile, pediatric patients who experienced both non-comorbid respiratory and increased work of breathing had a 5.76 times risk of requiring an intermediate level of care (p<0.05), and 9.32 times higher risk of requiring a PICU level of care (p<.05). Conclusion: It was found that both non-comorbid respiratory and increased WOB had a significant relationship with the level of care for pediatric patients with COVID-19. Nurse should take into account those clinical findings to increase the awareness in monitoring clinical deterioration in pediatric COVID-19 patients. [ABSTRACT FROM AUTHOR]

Background: Monitoring oxygen saturation in shocked patients is a challenging nursing procedure. Shock syndrome alters peripheral tissue perfusion and hinders peripheral capillary oxygen saturation (SpO2) measurements. Our study aimed to find a solution to this problem. The pharynx is expected to be an accurate SpO2 measurement site in shocked patients. We clinically evaluated the pharyngeal SpO2 measurements against the arterial oxygen saturation (SaO2) measurements. Methods: A prospective cohort research design was used. This study included 168 adult shocked patients. They were admitted to five intensive care units from March to December 2020 in an Egyptian hospital. A wrap oximeter sensor was attached to the posterior surface of an oropharyngeal airway (OPA) by adhesive tape. The optical component of the sensor adhered to the pharyngeal surface after the OPA insertion. Simultaneous pharyngeal peripheral capillary oxygen saturation (SpO2) and arterial oxygen saturation (SaO2) measurements were recorded. The pharyngeal SpO2 was clinically evaluated. Also, variables associated with the SpO2 bias were evaluated for their association with the pharyngeal SpO2 bias. Results: The pharyngeal SpO2 bias was − 0.44% with − 1.65 to 0.78% limits of agreement. The precision was 0.62, and the accuracy was 0.05. The sensitivity to detect mild and severe hypoxemia was 100%, while specificity to minimize false alarm of hypoxemia was 100% for mild hypoxemia and 99.4% for severe hypoxemia. None of the studied variables were significantly associated with the pharyngeal SpO2 bias. Conclusion: The pharyngeal SpO2 has a clinically acceptable bias, which is less than 0.5% with high precision, which is less than 2%. [ABSTRACT FROM AUTHOR]

Introduction: Lightning strikes have high morbidity and mortality rates. Thousands of fatalities are estimated to be caused by lightning worldwide, with the number of injuries being 10 times greater. However, evidence of lightning injuries is restricted to case reports and series and nonsystematic reviews. In this clinical review, we systematically select, score, and present evidence regarding lightning injuries.Material and Methods: We performed a systematic search for reviews and guidelines in the PubMed, Embase (OvidSP), MEDLINE (OvidSP), and Web of Science databases. All publications were scored according to the Levels of Evidence 2 Table of the Oxford center for Evidence-Based Medicine. The reviews were also scored using the scale for the quality assessment of narrative review articles (SANRA) and guidelines from the Appraisal of Guidelines for Research & Evaluation (AGREE II).Results: The search yielded 536 articles. Eventually, 56 articles were included, which consisted of 50 reviews, five guidelines and one overview. The available reviews and guidelines were graded as low to moderate evidence. Most damage from lightning injuries is cardiovascular and neurological, although an individual can experience complications with any of their vital functions. At the scene, initial treatment and resuscitation should focus on those who appear to be dead, which is called the reverse triage system. We proposed an evidence-based treatment protocol for lightning strike patients.Conclusion: It is vital that every lightning strike patient is treated according to standard trauma guidelines, with a specific focus on the possible sequelae of lighting injuries. All emergency healthcare professionals should acknowledge the risks and particularities of treating lighting strike injuries to optimize the care and outcomes of these patients. Our evidence-based treatment protocol should help prehospital and in-hospital emergency healthcare practitioners to prevent therapeutic mismanagement among these patients. [ABSTRACT FROM AUTHOR]

Mastocytosis is a rare disorder affecting both children and adults by gathering of functionally defective mast cells in the body's tissues. The World Health Organization (WHO) classified mastocytosis into cutaneous mastocytosis, systemic mastocytosis (SM), and mast cell sarcoma (MCS). We hereby present a case of retroperitoneal MCS with concurrent systemic mastocytosis and an undisclosed associated hematological neoplasm (SM-undisclosed AHN). The diagnosis of MCS and SM was made after the second biopsy over retroperitoneal mass, lymph node, and ovary for rapidly progressive disease with the presentation of unexplained recurrent flushing, palpitation, and shock, in addition to abdominal pain. A clonal myeloid neoplasm was also suspected by the karyotype and hemogram data. Unfortunately, the patient succumbed to the disease quickly. Apart from this unique case, the previously reported cases of SM with MCS in the literature were also reviewed. [ABSTRACT FROM AUTHOR]

Background: Intensive care management of diabetic ketoacidosis (DKA) is targeted to reverse ketoacidosis, replace the fluid deficit, and correct electrolyte imbalances. Adequate restoration of circulation and treatment of shock is key. Pediatric treatment guidelines of DKA have become standard but complexities arise in children with co-morbidities. Congenital nephrogenic diabetes insipidus (NDI) is a rare hereditary disorder characterized by impaired kidney concentrating ability and treatment is challenging. NDI and DKA together have only been previously reported in one patient. Case diagnosis/treatment: We present the case of a 12-year-old male with NDI and new onset DKA with hyperosmolality. He presented in hypovolemic shock with altered mental status. Rehydration was challenging and isotonic fluid resuscitation resulted in increased urine output and worsening hyperosmolar state. Use of hypotonic fluid and insulin infusion led to lowering of serum osmolality faster than desired and increased the risk for cerebral edema. Despite the rapid decline in serum osmolality his mental status improved so we allowed him to drink free water mixed with potassium phosphorous every hour to match his urinary output (1:1 replacement) and continued 0.45% sodium chloride based on his fluid deficit and replacement rate with improvement in his clinical status. Conclusions: This case illustrates the challenges in managing hypovolemic shock, hyperosmolality, and extreme electrolyte derangements driven by NDI and DKA, as both disease processes drive excessive urine output, electrolyte and acid–base imbalances, and rapid fluctuation in osmolality.

Background Multisystem Inflammatory Syndrome in Children (MIS-C) is a post-infectious complication of SARS-CoV-2 infection with overlapping features of Kawasaki disease and toxic shock syndrome. In May 2020, a provincial multidisciplinary working group was established in anticipation of emerging cases following the first wave of SARS-CoV-2 infections. Methodology Our centre established a multidisciplinary working group for MIS-C cases in British Columbia. The group developed guidelines using the World Health Organization MIS-C case definition. Guidelines were updated using quality improvement methods as new reports and our local experience evolved. We included all children who were evaluated in person or had samples sent to our centre for MIS-C evaluation from May 2020 to April 2021. We prospectively collected patient demographics, clinical and laboratory characteristics, and treatment. Results Fifty-two children were included. Eleven were diagnosed as confirmed MIS-C. Ten of the 11 MIS-C cases presented with shock. Gastrointestinal and mucocutaneous involvement were also prominent. Common laboratory features included elevated C-reactive protein, D-dimer, troponin, and brain natriuretic peptide. Four out of 11 (36%) had myocardial dysfunction and 3/11 (27%) had coronary artery abnormalities. All 11 patients had evidence of SARS-CoV-2 infection. Ten out of 11 (91%) received intravenous (IV) immunoglobulin and IV corticosteroids. Conclusion Our provincial cohort of MIS-C patients were more likely to present with shock and cardiac dysfunction, require ICU admission, and be treated with corticosteroids compared to ruled out cases. Our working group's evolving process ensured children with features of MIS-C were rapidly identified, had standardized evaluation, and received appropriate treatment in our province.

Although ovarian cancer is the second most common gynecological cancer, it is the most common gynecological malignancy that causes death. Approximately 75% of the patients are diagnosed at an advanced stage, and high-grade serous-type ovarian cancer is detected in most of these patients. The final pathology result in our case was high-grade serous ovarian carcinoma. Our patient, 39 years old, applied to our emergency department with complaints of inability to urinate for three days and new onset abdominal pain. We were consulted because of detection of an 11 cm solid mass and globe vesicle in the pelvic region detected on the computed tomography (CT) taken in the emergency department. The patient's initial hemoglobin value was 11.2 g/dL and the beta-human chorionic gonadotropin (B-HCG) value was negative. During the follow-up, the patient's hemoglobin values were 9.2 and then decreased to 8.6, 8.1, and 6.5 g/dL after which hypotensive shock developed in the patient. The patient was taken for an emergency laparotomy. Intra-operatively, 1500 mL of intra-abdominal hemorrhagic fluid and diffuse tumor fragments were observed. In the right adnexal area, approximately 11 cm of ruptured tumor tissue, which may originate from the ovary or uterus, was observed. It was observed that the Douglas pouch and uterine, internal iliac, and some parts of the external iliac arteries were extensively invaded by the tumor and active bleeding occurred. Total Abdominal Hysterectomy + Bilateral Salpingo-Oopherectomy (TAH+BSO) was performed on the patient. Additional surgical intervention could not be performed because the patient had extensive vascular tumor invasion, heavy bleeding, and was in hypotensive shock. Six anti-bleeding sponges were placed on intra-abdominal bleeding areas. In addition, packing was applied to the patient by placing four sterile compresses and soft drains inside the abdomen. Tranexamic acid was administered to the patient, and six units of red blood cell suspension and four units of fresh frozen plasma were transfused. The patient was transferred by ambulance to a higher institution, which is a gynecological oncology center, for follow-up, treatment, and complementary surgery. In this case, we aimed to draw attention to a rare case of ovarian malignancy rupture and hypotensive shock. [ABSTRACT FROM AUTHOR]

Background: European resuscitation guidelines describe several acceptable placements of defibrillator pads during resuscitation of cardiac arrest. However, no clinical trial has compared defibrillation efficacy between any of the different pad placements. Houston Fire Department emergency medical system (EMS) used anterior-posterior (AP) defibrillator pad placement before becoming a study site in the circulation improving resuscitation care trial (CIRC). During CIRC, Houston Fire EMS used sternal-apical (SA) pad placement.Methods: Data from electronic defibrillator records was compared between a pre-CIRC dataset and patients in the CIRC trial receiving manual cardiopulmonary resuscitation (CPR). Only shocks from patients with initial ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) were included. Measured outcome was defibrillation efficacy, defined as termination of VF/VT. The general estimatingequations model was used to study the association between defibrillation efficacy rates in the AP vs SA group.Results: In the pre-CIRC dataset, 207 included patients received 1023 shocks with AP pad placement, compared with 277 patients from the CIRC trial who received 1020 shocks with SA pad placement. There was no significant difference in defibrillation efficacy between AP and SA pads placement (82.1 % vs 82.2 %, p = 0.98).Conclusion: No difference was observed in defibrillation efficacy between AP and SA pad placement in this study. A randomized clinical trial may be indicated. [ABSTRACT FROM AUTHOR]

A retrospective study that compared children younger than 6 months versus older children of a Spanish cohort of patients diagnosed with Kawasaki disease between 2011 and 2016 (Kawa-Race study). From the 598 patients recruited, 42 patients were younger than 6 months (7%) and presented more frequently with an incomplete diagnosis of Kawasaki disease (52.4 vs 27.9%, p = 0.001). Cardiac abnormalities detected by echocardiography were more common in younger patients (52.4 vs 30%, p = 0.002). These younger patients presented with a higher proportion of coronary aneurysms as well (19 vs 8.6%, p < 0.001). Shock at diagnosis (9.5 vs 1.9%, p = 0.016) and admission to intensive care units (17.7 vs 4.1%, p = 0.003) were more frequent in patients younger than 6 months. There were no statistically significant differences in relation to infections, non-response to IVIG, or mid- or long-term outcomes. Conclusion: Data of the Spanish cohort are consistent with other American and Asian studies, although Spanish children younger than 6 months had a lower rate of non-response to IVIG and better clinical outcomes. A high index of suspicion should be considered for this population due to a higher risk of coronary abnormalities, presentation of shock, and admission to the intensive care unit. What is Known: •Children below 6 months of age with Kawasaki disease (KD) have different features compared to older. •Younger patients usually have an incomplete form of KD and coronary artery abnormalities. What is New: •Younger than 6 months with KD presented with shock and required admission to PICU more frequently compared to older. •Infections play a similar role in KD despite the age of the patients.

Purpose: Acute traumatic coagulopathy can result in uncontrolled haemorrhage responsible for the majority of early deaths after adult trauma. Data on the frequency, transfusion practice and outcome of severe trauma haemorrhage in paediatric patients are inconsistent. Methods: Datasets from paediatric trauma patients were retrieved from the registry of the German trauma society (TR-DGU®) between 2009 and 2016. Coagulopathy was defined by a Quick's value < 70% (INR (international normalized ratio) > 1.4) and/or thrombocytes ≤ 100 k upon emergency room admission. Children were grouped according to age in 4 different groups (A: 1–5, B: 6–10, C: 11–15 and D: 16–17 years). Prevalence of coagulopathy was assessed. Demographics, injury severity, haemostatic management including transfusions and mortality were described. Results: 5351 primary admitted children ≤ 17 years with an abbreviated injury scale (AIS) ≥ 3 and complete datasets were included. The prevalence of coagulopathy was 13.7% (733/5351). The majority of the children sustained blunt trauma (more than 90% independent of age group) and a combination of traumatic brain injury (TBI) and any other trauma in more than 60% (A, C, D) and in 53.8% in group B. Coagulopathy occurred the most among the youngest (A: 18.2%), followed by all other age groups with approximately 13%. Overall mortality was the highest in the youngest (A: 40.9%) and among the youngest patients with traumatic brain injury (A: 71.4% and B: 47.1%). Transfusion of packed red blood cells (pRBCs) and fresh frozen plasma (FFPs) occurred almost in a 2:1 ratio (or less) across all age subgroups. Conclusion: Traumatic haemorrhage in association with coagulopathy and severe shock is a major challenge in paediatric trauma across all age groups. [ABSTRACT FROM AUTHOR]

Background: Whole body ischemia and reperfusion injury after cardiac arrest leads to the massive inflammation clinically manifested in the post-cardiac arrest syndrome. Previous studies on the inflammatory effect on circulatory failure after cardiac arrest have either investigated a selected patient group or a limited part of the inflammatory mechanisms. We examined the association between cardiac arrest characteristics and inflammatory biomarkers, and between inflammatory biomarkers and circulatory failure after cardiac arrest, in an unselected patient cohort.Methods: This was a prospective study of 50 consecutive patients with out-of-hospital cardiac arrest. Circulation was invasively monitored from admission until day five, whereas inflammatory biomarkers, i.e. complement activation, cytokines and endothelial injury, were measured daily. We identified predictors for an increased inflammatory response, and associations between the inflammatory response and circulatory failure.Results: We found a marked and broad inflammatory response in patients after cardiac arrest, which was associated with clinical outcome. Long time to return of spontaneous circulation and high lactate level at admission were associated with increased complement activation (TCC and C3bc), pro-inflammatory cytokines (IL-6, IL-8) and endothelial injury (syndecan-1) at admission. These biomarkers were in turn significantly associated with lower mean arterial blood pressure, lower cardiac output and lower systemic vascular resistance, and increased need of circulatory support in the initial phase. High levels of TCC and IL-6 at admission were significantly associated with increased 30-days mortality.Conclusion: Inflammatory biomarkers, including complement activation, cytokines and endothelial injury, were associated with increased circulatory failure in the initial period after cardiac arrest.

Rationale: Peptic ulcer disease and variceal bleeding are two of the most common causes of gastrointestinal (GI) bleeding. GI bleeding can present with symptoms of hemodynamic instability such as tachycardia and shock. Patient's Concern: A 33-year-old man with confusion and hypotension (blood pressure: 70/40 mmHg and pulse rate: 140/min) was brought by emergency medical services from home to the emergency department without any companion. The patient was in undifferentiated shock. His hypotension was assessed with inferior vena cava (IVC) size and collapsibility, and rapid ultrasound in shock and hypotension (RUSH) protocol was used to investigate the cause of his shock. Following the RUSH protocol when scanning the IVC, parts of the stomach were seen in its vicinity and suspended heterogeneous particles were observed in the fluid. After seeing these particles, we suspected GI bleeding. Diagnosis: Endoscopy confirmed GI bleeding. Interventions: After placing an orogastric tube and suction, about 2 L of coffee-ground fluid with clots was removed. We started intravenous proton-pump inhibitors 80 mg bolus, followed by a continuous infusion of 8 mg/h. The patient received about 2 L of normal saline and 2 units of packed red blood cells to correct his hypotension. Outcomes: After being admitted to the GI ward and treated for three days, the patient was discharged from the hospital with a hemoglobin level of 11 g/dL and continued to have an outpatient follow-up at the clinic. Lessons: The use of gastric ultrasound in conjunction with the RUSH protocol can help to diagnose undifferentiated hypotensive shock. The components of the RUSH exam are the heart (H), IVC (I), Morrison's/FAST abdominal views with the aorta (MA), and pulmonary and pipes scanning (P), and can be memorized with the mnemonic: HI-MAP. We would like to introduce a new mnemonic: Hi-MAPS, adding stomach (S) to the RUSH protocol in undifferentiated hypotension and shock to evaluate upper GI bleeding. [ABSTRACT FROM AUTHOR]

Background: High levels of arterial oxygen pressures (PaO2) have been associated with increased mortality in extracorporeal cardiopulmonary resuscitation (ECPR), but there is limited information regarding possible mechanisms linking hyperoxia and death in this setting, notably with respect to its hemodynamic consequences. We aimed therefore at evaluating a possible association between PaO2, circulatory failure and death during ECPR.Methods: We retrospectively analyzed 44 consecutive cardiac arrest (CA) patients treated with ECPR to determine the association between the mean PaO2 over the first 24 h, arterial blood pressure, vasopressor and intravenous fluid therapies, mortality, and cause of deaths.Results: Eleven patients (25%) survived to hospital discharge. The main causes of death were refractory circulatory shock (46%) and neurological damage (24%). Compared to survivors, non survivors had significantly higher mean 24 h PaO2 (306 ± 121 mmHg vs 164 ± 53 mmHg, p < 0.001), lower mean blood pressure and higher requirements in vasopressors and fluids, but displayed similar pulse pressure during the first 24 h (an index of native cardiac recovery). The mean 24 h PaO2 was significantly and positively correlated with the severity of hypotension and the intensity of vasoactive therapies. Patients dying from circulatory failure died after a median of 17 h, compared to a median of 58 h for patients dying from a neurological cause. Patients dying from neurological cause had better preserved blood pressure and lower vasopressor requirements.Conclusion: In conclusion, hyperoxia is associated with increased mortality during ECPR, possibly by promoting circulatory collapse or delayed neurological damage.

Purpose: This study sought to recognize differences in clinical disease manifestations of spondylodiscitis depending on the causative bacterial species. Methods: We performed an evaluation of all spondylodiscitis cases in our clinic from 2013–2018. 211 patients were included, in whom a causative bacterial pathogen was identified in 80.6% (170/211). We collected the following data; disease complications, comorbidities, laboratory parameters, abscess occurrence, localization of the infection (cervical, thoracic, lumbar, disseminated), length of hospital stay and 30-day mortality rates depending on the causative bacterial species. Differences between bacterial detection in blood culture and intraoperative samples were also recorded. Results: The detection rate of bacterial pathogens through intraoperative sampling was 66.3% and could be increased by the results of the blood cultures to a total of 80.6% (n = 170/211). S. aureus was the most frequently detected pathogen in blood culture and intraoperative specimens and and was isolated in a higher percentage cervically than in other locations of the spine. Bacteremic S. aureus infections were associated with an increased mortality (31.4% vs. overall mortality of 13.7%, p = 0.001), more frequently developing complications, such as shock, pneumonia, and myocardial infarction. Comorbidities, abscesses, length of stay, sex, and laboratory parameters all showed no differences depending on the bacterial species. Conclusion: Blood culture significantly improved the diagnostic yield, thus underscoring the need for a structured diagnostic approach. MSSA spondylodiscitis was associated with increased mortality and a higher incidence of complications. [ABSTRACT FROM AUTHOR]

Introduction. Cholera is gastroenteritis caused by Vibrio cholerae. It presents with vomiting, severe secretory diarrhoea, and dehydration. It can cause severe complications with severe electrolyte imbalances and oligoanuric acute kidney injury due to acute tubular necrosis secondary to dehydration or infection itself. However, cholera presenting with significant proteinuria and acute kidney injury has not been reported. Hence, this study was conducted. Aims and Objectives. This aim of this study was to assess clinical features, treatment, and prognosis of AKI in cholera patients; to correlate proteinuria with AKI in cholera patients; and to compare cholera patients with normal kidney function and those with AKI. Material and Methods. It was a retrospective observational study involving patients with cholera. Information regarding cholera patients with acute kidney injury, proteinuria, and prognosis were collected. Results. Most of the patients had significant vomiting, moderate-to-severe diarrhoea, dehydration, and hypovolaemic shock. Cholera caused severe complications such as severe electrolyte imbalances including hyponatraemia and hypokalaemia, acute kidney injury, and proteinuria secondary to dehydration or infection. A surprising finding noted was the lack of significant association between the onset of acute kidney injury and usual risk factors such as hypovolaemic shock and dehydration. It was found that proteinuria had influenced the onset of acute kidney injury, but it did not influence recovery. As there was complete recovery in kidney function, none of the cases required kidney biopsy. There was no mortality noted. Conclusions. This study points towards the rare occurrence of proteinuria and acute kidney injury in Vibrio cholerae infection with spontaneous remission of kidney disease with appropriate therapy.

The protocol was made according to the earlier described methodology of heat shock induction. • A significant difference was observed in the G41-UD group; p < 0.0005. • The lowest body temperature of the rats was observed, from normothermia, and the highest temperature after death, 37.87 ± 0.62 °C vs 41.20 ± 0.76 °C, the difference between all three groups is p < 0.0005. • Exposure of Wistar rats to water temperatures in the CG and G41 groups led to a significant change in core temperature. The research aimed to determine individual variations in different core temperature measurements before the experiment, after submersion, after 20 min of exposure for heat stroke. Rats were divided into three groups depending on the temperature and length of exposure to water: CG, G41-20 and G41-UD. The protocol was made according to the earlier described methodology of heat shock induction. A significant difference was observed in the G41-UD group; p < 0.0005. The lowest body temperature of the rats was observed, from normothermia, and the highest temperature after death, 37.87 ± 0.62 °C vs 41.20 ± 0.76 °C, the difference between all three groups is p < 0.0005. Exposure of Wistar rats to water temperatures in the CG and G41 groups led to a significant change in core temperature. In the control group, the thermoregulatory mechanism firmly established normothermia, while hyperthermia was revealed in the G41 group during the 20-minute exposure. [ABSTRACT FROM AUTHOR]

Topics include the patient had been well until 20 hours before this admission, and nausea developed after he ate rice, and lo mein leftovers from a restaurant meal, the multiple episodes of emesis occurred with vomitus that was either bilious or red-brown, and the abdominal pain were followed by the development of chills.

Renal ischemia-reperfusion (I/R) injury mainly causes acute kidney injury (AKI) after renal transplantation, trauma, sepsis, and hypovolemic shock. Patients with renal I/R injury are frequently associated with a poor prognosis. Traditional Chinese medicine (TCM) has been used for the prevention and treatment of various diseases in China and other Asian countries for centuries. Many studies have shown the protective effect of TCM on renal I/R injury, due to its diverse bioactive components. The potential mechanisms of TCMs on renal I/R injury include anti-inflammation, antioxidative effect, anti-cell death, downregulation of adhesion molecule expression, regulation of energy metabolism by restoring Na+-K+-ATPase activity, and mitochondrial fission. This review summarizes the major developments in the effects and underlying mechanisms of TCMs on the renal I/R injury. [ABSTRACT FROM AUTHOR]

Shock in newborns and preterm infants carries significant morbidity and mortality risks unless there is early recognition and adequate treatment. Signs may only be identified in the late decompensated phase with lactic acidosis, cellular disruption, and irreversible multiorgan damage. In neonates, the etiopathological origin is unique, particularly in extremely preterm infants with a complicated postnatal transition phase, an immature myocardium, and high peripheral systemic resistance. Hypovolemic shock shortly after birth is uncommon and may complicate fetomaternal or fetoplacental transfusion, abruptio placenta, intracranial hemorrhage, or capillary leak syndrome. Without a blood loss history, secondary clinical assessment may reveal the underlying etiology and facilitate targeted interventions. [ABSTRACT FROM AUTHOR]

Rationale: There are no prospective observational studies exploring the relationship between relative hypotension and adverse kidney-related outcomes among critically ill patients with shock.Objectives: To investigate the magnitude of relative hypotension during vasopressor support among critically ill patients with shock and to determine whether such relative hypotension is associated with new significant acute kidney injury (AKI) or major adverse kidney events (MAKE) within 14 days of vasopressor initiation.Methods: At seven multidisciplinary ICUs, 302 patients, aged ≥40 years and requiring ≥4 hours of vasopressor support for nonhemorrhagic shock, were prospectively enrolled. We assessed the time-weighted average of the mean perfusion pressure (MPP) deficit (i.e., the percentage difference between patients' preillness basal MPP and achieved MPP) during vasopressor support and the percentage of time points with an MPP deficit > 20% as key exposure variables. New significant AKI was defined as an AKI-stage increase of two or more (Kidney Disease: Improving Global Outcome creatinine-based criteria).Measurements and Main Results: The median MPP deficit was 19% (interquartile range, 13-25), and 54% (interquartile range, 19-82) of time points were spent with an MPP deficit > 20%. Seventy-three (24%) patients developed new significant AKI; 86 (29%) patients developed MAKE. For every percentage increase in the time-weighted average MPP deficit, multivariable-adjusted odds of developing new significant AKI and MAKE increased by 5.6% (95% confidence interval, 2.2-9.1; P = 0.001) and 5.9% (95% confidence interval, 2.2-9.8; P = 0.002), respectively. Likewise, for every one-unit increase in the percentage of time points with an MPP deficit > 20%, multivariable-adjusted odds of developing new significant AKI and MAKE increased by 1.2% (0.3-2.2; P = 0.008) and 1.4% (0.4-2.4; P = 0.004), respectively.Conclusions: Vasopressor-treated patients with shock are often exposed to a significant degree and duration of relative hypotension, which is associated with new-onset, adverse kidney-related outcomes.Study registered with Australian New Zealand Clinical Trial Registry (ACTRN 12613001368729).

Background: Purpura fulminans (PF) is a potentially fatal uncommon disorder of intravascular thrombosis and is clinically characterized by rapidly progressive hemorrhagic infarction of the skin. Objective: To describe the clinical feature and outcome of a series of patients with PF. Materials and Methods: A descriptive study based on review of case records was carried out at a tertiary care hospital in Kolkata. Results: Twenty three consecutive cases seen over a period of 8 years were studied. The age range was 4 days to 78 years (mean 35.6 years) with a male to female ratio of 1:2.8. Hemorrhagic rash was the universal presenting symptom. Other major presenting features included pneumonia (26.1%), sudden-onset shock syndrome (21.7%), and urinary tract infection (17.4%). All patients presented with retiform purpura and lesional necrosis and 8 (34.8%) patients had associated peripheral gangrene. Nineteen (82.6%) patients had sepsis and 60.9% patients had vesiculo-bullous lesion. Pneumococcus was the most common (26.1%) pathogenic organism detected. The precise cause of PF could not be detected in two (8.7%) patients. One patient (4.3%) with neonatal PF had protein C deficiency. All patients had evidence of disseminated intravascular coagulation (DIC). One patient had to undergo a below knee surgical amputation and one patient had autoamputation of the digits. Ten (43.5%) patients succumbed to their illness. Seven of the 8 patients who had peripheral gangrene had a fatal outcome. Limitations: Relatively small sample size and a referral bias were a few limitations of the present study. Conclusion: The present study emphasizes that PF is a cutaneous marker of DIC. Association of peripheral gangrene, leukopenia and neutropenia may be the reason for the high mortality rate. [ABSTRACT FROM AUTHOR]

Background: Acute kidney injury (AKI) is common in hospitalized and critically ill children. Apart from primary kidney disease, etiologies of AKI are usually related to systemic disease and nephrotoxic insult. This study examines the incidence, characteristics, and mortality risks of AKI in critically ill children without primary renal disease or previously known chronic kidney disease. Methods: A retrospective cohort study was conducted of patients aged 1–18 years, diagnosed with AKI (excluding severe glomerulonephritis and previously known chronic kidney disease) in pediatric intensive care units between 2013 and 2016. Acute kidney injury was defined according to the Kidney Disease Improving Global Outcomes classifications. Cox proportional hazards regression analysis was employed to assess the relationship between the risk factors and mortality. Results: Of 1,377 pediatric intensive care unit patients, 253 (18.4%) developed AKI and only 169 (12.3%) who did not have previously known renal disease were included. Of these 169 AKI patients, the mean age was 8.1 ± 4.7 years; 88 (52.1%) patients were male; and 60 (35.5%) patients had AKI stage 3. The most common etiologies of AKI were sepsis (76.9%) and shock (64.5%). Fifty‐three (31.4%) of those patients died during admission. The risk factors for death were the need for mechanical ventilation (adjusted hazard ratio, 17.82; 95% CI, 2.41–132.06) and AKI stage 3 (adjusted hazard ratio, 2.32; 95% CI, 1.07–5.00). Conclusions: Acute kidney injury in critically ill children without previously known renal disease was approximately two‐thirds of the overall incidence. The risk factors of in‐hospital death were the use of mechanical ventilation, and AKI stage 3. [ABSTRACT FROM AUTHOR]

The article provides information on hypovolaemic shock, which is characterized by a loss of intravascular volume of 15% or more, leading to inadequate perfusion of the tissues. Topics discussed include four main pathological mechanisms that can result in a state of shock, pathophysiology and symptoms of hypovolaemic shock, and risk factors of the condition.

Since the outbreak of coronavirus disease 2019 (COVID-19), clinicians have tried every effort to understand the disease, and a brief portrait of its clinical features have been identified. In clinical practice, we noticed that many severe or critically ill COVID-19 patients developed typical clinical manifestations of shock, including cold extremities and weak peripheral pulses, even in the absence of overt hypotension. Understanding the mechanism of viral sepsis in COVID-19 is warranted for exploring better clinical care for these patients. With evidence collected from autopsy studies on COVID-19 and basic science research on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and SARS-CoV, we have put forward several hypotheses about SARS-CoV-2 pathogenesis after multiple rounds of discussion among basic science researchers, pathologists, and clinicians working on COVID-19. We hypothesise that a process called viral sepsis is crucial to the disease mechanism of COVID-19. Although these ideas might be proven imperfect or even wrong later, we believe they can provide inputs and guide directions for basic research at this moment. [ABSTRACT FROM AUTHOR]

Background: Occult hypoperfusion (OH), or global hypoperfusion with normal vital signs, is a risk factor for poor outcomes in elderly trauma patients. We hypothesized that OH is associated with worse outcomes than shock in both young and elderly trauma patients.Methods: We conducted a single-center cohort study of adult (16 years or older) trauma patients from 2016 to 2018 with base excess measured on arrival. Perfusion states were defined as shock if heart rate was >120 beats/min or systolic blood pressure was <90 mmHg; OH if base excess was < -2 mmol/L, heart rate was <120 beats/min, and systolic blood pressure was >90 mmHg; and normal for all others. Patients were stratified as young (younger than 55 years) or elderly (55 years or older). Bayesian regression was used to assess the relationship between arrival perfusion state and mortality or serious complication.Results: Of 3,126 included patients, 808 were elderly. Rates of shock (33% and 31%) and OH (25% and 23%) were similar in young and elderly patients, respectively. OH on arrival was associated with higher odds of mortality or serious complication than normal perfusion, regardless of age group. Compared with shock, OH was associated with an odds ratio of 1.21 (95% CI, 0.97 to 1.52, posterior probability 96%) for poor outcomes in elderly patients and an odds ratio of 0.52 (95% CI, 0.42 to 0.65, posterior probability <1%) for poor outcomes in younger patients. Findings were similar on sensitivity analysis, excluding shock patients with base excess ≥ -2 mmol/L.Conclusions: In elderly but not younger patients, OH is associated with worse outcomes than shock. Although shock parameters might need to be redefined in elderly patients, more attention is necessary for the diagnosis and treatment of all hypoperfused states in this age group.

Background: Fatal burns and related injuries are major cause of death and disability. There are certain pathological changes such as lungs shows necrotizing pneumonia, congestion of alveolar walls, capillary proliferation, intra alveolar oedema, giant epithelial cells Objective: To study on the cause of death due to burn cases and histopathological changes in north Indian setting. Method: This was a cross-sectional study. All autopsies with history of burn injury were studied to find out the significant histopathological change in lung. Cases was thoroughly studied using specially designed proforma that included demographic profile of deceased, history from relatives, police & hospital records, autopsy findings. Results: The most common cause of death due to burn injury was found to be Sepsis (48.2%) and neurogenic shock (29.5%). On histopathological examination, Congestion in trachea was present in majority 434 (78.9%) cases while Tracheal soot particles were present in only 40 (7.3%) cases. Specimens of 375 cases were available for histopathology out of which 52 (13.9%) specimens were autolyzed. Changes suggestive of Pneumonia (50.1%), Congestion (83.7%), alveolar and interstitial haemorrhage (63.2%) were present in majority of the cases while changes suggestive of alveolar interstitial edema (64.3%), alveolar wall disruption (66.1%), inflammatory cells (55.5%), hyaline membrane (79.7%) and Fibrin strands (79.7) were absent in majority of cases. Capillary dilatation was present in 39.2%. Conclusion: In the present study, an important observation in burn deaths is the Sepsis and Neurogenic shock. Congestion in trachea was most common on histopathological change. [ABSTRACT FROM AUTHOR]

Protein-energy malnutrition (PEM), resulting from depleted energy and nutrient stores, compromises the body's defense systems and may exacerbate sepsis and its impact. However, population-based studies examining the association of PEM on the prevalence and health-care burden of sepsis are lacking. To investigate the relationship between PEM and sepsis, influence of PEM on clinical outcomes of sepsis, and impact of PEM on trends in sepsis mortality. The primary study is a retrospective cohort analysis of the 2012-2014 National Inpatient Sample (NIS) patient discharge records. Secondary analyses are cross-sectional study on the 2014 NIS and trend analysis on 2007-2014 NIS. The primary study included adult inpatient hospitalizations for sepsis in the United States. Mortality, complicated sepsis, and 10 other metrics of clinical outcomes and health care utilization. First, patients with sepsis (2014 NIS) were stratified into two groups: uncomplicated (without shock) and complicated (with shock). The adjusted odds ratio of having sepsis (total, uncomplicated, and complicated) was estimated with PEM as predictor using logistic regressions (binomial and multinomial). Second, among patients with sepsis (2012-2014 NIS), PEM cases were matched to cases without PEM (no-PEM) using a greedy-algorithm based propensity-matching methodology (1:1), and the outcomes were measured with conditional regression models. Finally, the trend in mortality from sepsis was calculated, stratified by PEM status, as an effect modifier, using Poisson models (2007-2014 NIS). All models accounted for the complex sampling methodology (SAS 9.4). In 2014, PEM was associated with higher odds for sepsis (3.97 [3.89 to 4.05], P <0.0001) and complicated vs uncomplicated sepsis (1.74 [1.67 to 1.81], P <0.0001). From 2012-2014, about 18% (167,133 of 908,552) of hospitalizations for sepsis had coexisting PEM. After propensity matching, PEM was associated with higher mortality (adjusted odds ratio: 1.35 [1.32 to 1.37], P <0.0001), cost ($160,724 [159,517 to 161,940] vs $86,650 [85,931 to 87,375], P <0.0001), length of stay (14.8 [14.9 to 14.8] vs 8.5 [8.5 to 8.6] days, P <0.0001), adverse events, and resource utilization. Although mortality in sepsis has been trending down from 2007-2014 (−1.19% per year, P trend<0.0001), the decrease was less pronounced among those with PEM vs no-PEM (−0.86% per year vs −1.29% per year, P <0.0001). PEM is a risk factor for sepsis and associated with poorer outcomes among patients with sepsis. A concerted effort involving all health care workers in the prevention, identification, and treatment of PEM in community-dwelling people before hospitalization might mitigate against these devastating outcomes.

The objective of the present study was to identify risk factors for mortality at admission in children admitted to the Pediatric Intensive Care Unit (PICU) with acute gastroenteritis (AGE) with severe dehydration and shock. This was a retrospective chart review of all cases of AGE with severe dehydration and shock admitted to the PICU from 2012 to 2017. Children who died during hospital stay were compared with those who survived. A total of 62 children were admitted with AGE to the PICU during this period. Twenty-four children (39%) died. The following variables were found to be significantly associated with death on univariate analysis: clinical pallor (p = 0.01), thrombocytopenia (p = 0.018), elevated leucocyte count (p = 0.02), hypoalbuminemia (p = 0.02) and severe acute malnutrition (SAM) (p = 0.04). On multivariate analysis, only hypoalbuminemia {RR [95% CI: 2.6 (1.27 to 9.21)]; 0.039} and SAM {RR [95% CI: 4.9 (1.12 to 10)]; 0.045} remained statistically significant. Children admitted with severe dehydration and shock had high mortality rates. These children were a sicker subset with probable sepsis. Severe acute malnutrition and hypoalbuminemia were associated with increased risk of death in these patients. [ABSTRACT FROM AUTHOR]

Objective: To highlight changing trends of the clinical spectrum, and compare the management options and predictors of Fournier's gangrene (FG) outcomes in a tertiary care referral center. Material and methods: This study included patients with FG between August 2005 and July 2017. Patients were classified as "responders" and "nonresponders." We compared the baseline characteristics, clinical spectrum, biochemical data, management modalities, outcomes, and FG severity index (FGSI) and age-adjusted Charlson Comorbidity Index (ACCI) between responders and nonresponders. Results: We studied 72 patients and further divided them to responders (60 patients) and non-responders (12 patients). All were males; the mean age was 56.27+19.27 years (range, 47--85 years). The most common complaints were perineal discomfort (n=62; 86.1%) and fever (n=48; 66.7%). FG originated from the penoscrotal region in 64 patients (88.8%) and perineal region in 8 patients. Diabetes mellitus was the most common comorbidity (36%). The mean duration of the presentation was 10.19 days (range, 7--30 days). Sixteen patients underwent split skin grafting. The mortality rate was 8.3%. Nonresponders had distinct findings relative to responders: advanced age (71.5±7.17 vs. 53.23±19.85 years; p=0.00); high blood sugar (245.83±116.26 vs. 139.06±35.64 mg/dL; p<0.01); leukocytosis (27166.67±10295.75 vs. 10558.4±3130.64 cumm; p<0.01); elevated serum creatinine (3.78±1.43 vs. 1.38±1.00; p<0.01); hyponatremia (127.33±11.84 vs. 137.33±3.42 meq/l; p<0.01), elevated international normalized ratios (1.66±0.28 vs. 1.32±0.07; p<0.01); and high FGSI (9.83±1.11 vs. 6.46±1.68;p<0.01) and ACCI scores (6.33±0.49 vs. 5±0.82; p<0.01). On univariate and multivariate regression analysis, raised blood sugar and deranged international normalized ratios at presentation were significantly associated with decreased response to treatment (p<0.05). Conclusion: An advanced age, diabetes mellitus, renal impairment, leukocytosis, altered sensorium, shock at presentation, deranged international normalized ratios, and high FGSI and ACCI scores can be used as predictors for poor response. FG risk scores adequately characterize the severity and prognosis of FG, but clinician's judgement is vital. The management comprises of a multidisciplinary approach, including parenteral antibiotics, urgent surgical debridement, and comorbidities optimization. [ABSTRACT FROM AUTHOR]

Vasodilatory shock is a critical manifestation of cardiovascular failure. There is uncontrolled vasodilation and vascular hyporesponsiveness to endogenous vasoconstrictors, causing the failure of physiologic vasoregulatory mechanisms. Unfortunately, only few randomized studies exist to guide clinical management and hemodynamic stabilization in patients who do not respond to the standard approach of managing vasodilatory shock. The present review offers the latest updates in management of this important clinical entity and a guidance framework for future research. [ABSTRACT FROM AUTHOR]

Distributive shock is a serious complication in patients with chronic or end-stage liver disease, and can be exacerbated by vasoplegia in this patient population. Vasoplegic syndrome (VS) is a state of shock refractory to catecholamines and vasopressin that is often multifactorial in liver failure patients, and can occur in any phase of liver transplantation (LT) [i.e., pre-transplantation, intraoperative, and post-transplantation]. Methylene blue (MB) has been a well-established pharmacologic therapy for VS. However, it has been known to cause dose-related toxicity. Hydroxocobalamin (HXC) is not currently FDA approved for the management of VS, but studies have demonstrated its ability to cause an increase in systolic blood pressure by hypothesized mechanisms with only minimal side effects. To date, only three other reports have demonstrated the use of HXC in LT patients, which highlighted its use both intraoperatively and post-transplantation. Our report illustrates the utility of HXC in four LT patients with VS. Two of these cases illustrate the usefulness of HXC in the pre-transplantation period, which has never been previously reported. HXC is a useful pharmaceutical agent in the management of VS, especially if contraindications to MB exist or in cases of MB-resistant vasoplegia. Further studies with large sample sizes are necessary to ascertain the optimal dosage of HXC in LT patients. [ABSTRACT FROM AUTHOR]
