Case report of scrub typhus complicated by hypokalemia and multiple organ dysfunction syndrome

ABSTRACT CONTEXT: Scrub typhus, caused by Orientia tsutsugamushi, has a wide range of clinical manifestations, including meningoencephalitis, acute renal failure, pneumonitis, myocarditis, and septic shock. However, there are no documented cases of scrub typhus with hypokalemia. In this report, we present a case of scrub typhus with hypokalemia and multiple organ failure syndrome, highlighting the importance of electrolyte imbalance in patients with scrub typhus. CASE REPORT: A 59-year-old woman presented to the emergency department with abdominal pain that had been present for 1 day. On admission, the physical examination and laboratory test results indicated that the patient had renal, liver, and circulatory failure, and hypokalemia. She developed meningitis and disseminated intravascular coagulation during hospitalization. She recovered with appropriate management, and was discharged on day 17. CONCLUSION: This report highlights the potential for atypical presentations of scrub typhus, including a previously undocumented association with hypokalemia. Although the contribution of hypokalemia to the patient's clinical course remains uncertain, this case underscores the importance of considering electrolyte imbalance in the management of patients with scrub typhus. Further research is warranted to better understand the relationship between scrub typhus and electrolyte imbalance.

A las 24 horas de ingreso a cuidado intensivo, ocurrió el parto prematuro vaginal. La embarazada desarrolló enfermedad renal crónica etapa KDIGO 5 ( V) y se encuentra en espera de trasplante renal. Por su parte, la recién nacida prematura viva presentó asfixia neonatal severa, displasia broncopulmonar y encefalopatía hipóxico-isquémica. Conclusiones El embarazo adolescente complicado es una emergencia sanitaria. El diagnóstico y manejo oportuno de la pielonefritis, shock séptico y disfunción orgánica asociada a la sepsis pueden evitar mortalidad y secuelas permanentes materna y/o neonatal.

Introduction Adolescent pregnancy is a physiological process, but it can evolve with premature delivery, severe obstetric or clinical pathologies, mortality, or sequelae for mother and child. We aim to report the progressive multiple organ dysfunction syndrome secondary to pyelonephritis and sepsis during prepartum, delivery, and puerperium of adolescent pregnancy and its sequelae. Case report A 14-year-old adolescent with a pregnancy of 27 weeks of gestation controlled from 8 to 25 weeks. She was urgently admitted to the high-risk obstetric unit due to signs of preterm labor, pyelonephritis, and acute renal injury. Treatment was started with intravenous cefazolin and betamethasone for lung maturation, oral nifedipine, and magnesium sulfate to prevent preterm labor and fetal neuronal protection, evolving with sustained hypotension and septic shock. At 13 hours after admission, she was transferred to the intensive care unit, where she evolved with persistent and progressive multiple organ failure for 28 days, progressively affecting the cardiovascular, hematologic, respiratory, and gastrointestinal systems. She was treated with vasoactive drugs, antibiotics, invasive mechanical ventilation, ultrafiltration, hemodialysis, pleural drainage, and cholecystectomy. Twenty-four hours after admission to intensive care, preterm vaginal delivery occurred. She developed chronic kidney disease stage KDIGO 5 (Kidney Disease Improving Global Outcomes V) and is awaiting renal transplantation. On the other hand, the preterm newborn presented severe neonatal asphyxia, bronchopulmonary dysplasia, and hypoxic-ischemic encephalopathy. Conclusion Complicated adolescent pregnancy is a health emergency. Avoiding delays in the diagnosis and treatment of pyelonephritis, septic shock and the progressive multiple organ dysfunction syndrome can prevent mortality and permanent sequelae, both maternal and neonatal.

Analysis of therapeutic plasma exchange combined with continuous venovenous hemofiltration in the treatment of children with severe sepsis and multiple organ dysfunction syndrome / 中华实用儿科临床杂志

Objective:To investigate the therapeutic potential of therapeutic plasma exchange (TPE) combined with continuous venovenous hemofiltration (CVVH) in the treatment of children with severe sepsis and multiple organ dysfunction syndrome (MODS).Methods:It was a prospective randomized controlled study (RCT) involving 70 children with severe sepsis and MODS admitted to Anyang Maternal and Child Health Hospital from February 2019 to February 2023.According to random number table method, they were randomly divided into combination group (35 cases) and CVVH group (35 cases). Patients in the CVVH group were treated with CVVH alone, and those in the combination group were treated with TPE combined with CVVH.The antibiotic use time of the two groups was recorded and compared by the t test.The prothrombin time (PT), thrombin time (TT), partial prothrombin time (APTT), fibrinogen (FIB), and serum levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), high mobility group protein B1 (HMGB1), Toll-like receptor 4 (TLR4) and soluble receptor (sFLT) levels before treatment and 48 h and 72 h after treatment were compared by the repeated measurement ANOVA for the overall comparison at multiple time points, and LSD- t test for pair-wise comparison.The 28-day survival of the two groups was recorded and compared by the Chi- square test. Results:The PT, TT and APTT at 48 h and 72 h after treatment were significantly lower in the combination group than those of CVVH group (all P<0.05). The FIB at 48 h[(2.15±0.42) g/L vs.(1.84±0.31) g/L]and 72 h after treatment [(2.89±0.27) g/L vs.(2.49±0.20) g/L]were significantly higher in the combination group than those of CVVH group (all P<0.05). The duration of antibiotic use in the combination group was significantly shorter than that of CVVH group [(11.33±1.16) d vs.(13.54±1.92) d, t=5.828, P<0.05]. Serum levels of IL-1β, IL-6 and TNF-α at 48 h and 72 h were significantly lower in the combination group than those of CVVH group (all P<0.05). Serum levels of HMGB1, TLR4 and sFLT at 48 h and 72 h were significantly lower in the combination group than those of CVVH group (all P<0.05). The 28-day survival of the combination group was significantly higher than that of CVVH group (94.29% vs.77.14%, χ2=4.200, P=0.040). Conclusions:TPE combined with CVVH can improve the coagulation function and inflammatory factor levels in children with severe sepsis and MODS, which may achieve therapeutic objectives by regulating the levels of HMGB1, TLR4 and sFLT, and improve the short-term prognosis.

Clinical value of myoglobin in predicting multiple organ dysfunction in wasp sting patients / 中华急诊医学杂志

Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.

Efficacy of plasma exchange in children with severe hemophagocytic syndrome: a prospective randomized controlled trial / 中国当代儿科杂志

OBJECTIVES@#To investigate the efficacy and application value of plasma exchange as an adjuvant therapy in children with hemophagocytic syndrome (HPS).@*METHODS@#A prospective randomized controlled trial was designed. Forty children with severe HPS were enrolled, who were treated in the pediatric intensive care unit (PICU) of Hunan Children's Hospital from October 2018 to October 2020. The children were randomly divided into a plasma exchange group and a conventional treatment group using a random number table, with 20 children in each group. The children in the conventional treatment group received etiological treatment and conventional symptomatic supportive treatment, and those in the plasma exchange group received plasma exchange in addition to the treatment in the conventional treatment group. The two groups were compared in terms of general information, clinical symptoms and signs before and after treatment, main laboratory markers, treatment outcome, and prognosis.@*RESULTS@#Before treatment, there were no significant differences between the two groups in gender, age, course of the disease before admission, etiological composition, pediatric critical illness score, involvement of organ or system functions, and laboratory markers (P>0.05). After 7 days of treatment, both groups had remission and improvement in clinical symptoms and signs. After treatment, the plasma exchange group had significantly lower levels of C-reactive protein, procalcitonin, and serum protein levels than the conventional treatment group (P<0.05). The plasma exchange group also had significantly lower levels of alanine aminotransferase and total bilirubin than the conventional treatment group (P<0.05). The length of stay in the PICU in the plasma exchange group was significantly shorter than that in the conventional treatment group (P<0.05). The plasma exchange group had a significantly higher treatment response rate than the conventional treatment group (P<0.05). There were no significant differences between the two groups in the total length of hospital stay and 3-month mortality rate (P>0.05).@*CONCLUSIONS@#Plasma exchange as an adjuvant therapy is effective for children with severe HPS. It can improve clinical symptoms and signs and some laboratory markers and shorten the length of stay in the PICU, and therefore, it may become an optional adjuvant therapy for children with severe HPS.

A case of tsutsugamushi disease complicated by multiple organ dysfunction syndrome treated by extracorporeal membrane oxygenation / 中华危重病急救医学

Tsutsugamushi disease is an acute infectious disease caused by Rickettsia. Occasionally it has been reported in Macau, China. Critical cases are rare. Because the clinical manifestations of tsutsugamushi disease are non-specific and diverse, if not diagnosed and treated in time, the disease may progress to multiple organ dysfunction syndrome (MODS), severe acute respiratory distress syndrome (ARDS), and even death. A patient with tsutsugamushi disease complicated by MODS was admitted to the intensive care unit (ICU) of Kiang Wu Hospital in Macau, China on September 30, 2021. Combined with the history of outdoor activities (exposure to chigger mite larvae), clinical symptoms and signs (characteristic eschar of tsutsugamushi disease was found on the abdominal skin), related laboratory examinations (Weil-Felix test: negative). Diagnosis of tsutsugamushi disease with MODS. After admission, the patient was treated by anti-infection, correction of coagulation dysfunction, tracheal intubation and mechanical ventilation, noradrenalin to maintain blood pressure, continuous renal replacement therapy (CRRT), but the condition didn't improve significantly. We initiated veno-venous ECMO (VV-ECMO), which was initially setted blood flow to 5 L/min (70 mL·kg -1·min -1), rotate speed to 3 500 rpm, fractional concentration of inspired oxygen (FiO 2) to 1.00. Heparin was used as anticoagulant and activated coagulation time (ACT) was kept between 180 and 200 seconds. Meanwhile the speed of fluid removal in CRRT was adjusted. After 9 hours of ECMO support, the oxygenation improved, the blood flow of ECMO was reduced to about 4 L/min (58 mL·kg -1·min -1), rotate speed to 3 000 rpm. The patient's condition improved after 4 days of ECMO treatment and her ECMO flow rate and FiO 2 could be decreased gradually. On hospital day 5, ECMO was removed. Eight days on mechanical ventilation, the patient was successfully weaned and extubated. On day 11 of hospitalization, weaned the CRRT and turned to intermittent hemodialysis. The patient was transferred out of ICU due to her stable condition on the 12th day hospitalization. After that, her spontaneous urine output increased gradually. The functions of various organs returned to normal. After 36 days of hospitalization, she recovered and was discharged.

Effect of plasma exchange and continuous blood purification on multiple organ dysfunction in children with bee sting poisoning / 中华急诊医学杂志

Objective:To investigate the effect of plasma exchange (PE) and continuous blood purification(CRRT) on children with bee sting poisoning and multiple organ dysfunction syndrome (MODS).Methods:From January 2016 to September 2019, 37 children aged 9 months to 11 years with bee sting and MODS were treated with dexamethasone 0.5 mg/kg or methylprednisolone 3 mg-5 mg/kg anti allergic and anti-inflammatory and organ support. Among them, 26 cases were treated with plasma exchange and continuous blood purification (treatment group), and the rest 11 cases were only given conventional treatment, but did not receive blood purification treatment (control group).The critical illness score, liver and kidney functions, myolysis, pulmonary hemorrhage/pulmonary edema, coagulation disorders, shock, hemolysis, gastrointestinal failure and other organ damage, ICU stay time, mechanical ventilation time, organ dysfunction recovery time and clinical outcomes were retrospectively analyzed. In the treatment group, 18 cases started blood purification before 12 h after MODS (early treatment group) and 8 cases started blood purification after 12 h (delayed treatment group).Results:There was no significant difference in age, sex, child critical illness score, onset time and organ function damage between the treatment and control groups ( P>0.05). The cure rate of the treatment group was higher than that of the control group [(25/26 (96.15%) vs 8/11 (72.73%), P=0.036]. There was no significant difference in ICU stay between the control group and the treatment group [(10.03±7.74) d vs (12.01±6.95) d, P>0.05]. Among the 25 survivors in the treatment group, one patient had mild renal function damage and one patient had multiple necrosis of skin, subcutaneous and muscle tissue. Compared with 4 of the 8 survivors in the control group, the residual organ function damage in the treatment group was significantly less than that in the control group [(2/25 (8.00%) vs 4/8 (50.00%), P=0.031)].The recovery of liver function, renal function, myolysis and hemolysis in the treatment group was faster than those in the control group (all P < 0.05). The initiation of blood purification within 12 h after the occurrence of MODS required fewer times of plasma exchange and shorter CRRT time, ICU stay and ventilator time (all P < 0.05). Conclusions:In children with bee sting combined with MODS, plasma exchange and continuous blood purification can achieve better therapeutic effect and better clinical outcome.

Establishment of An Improved Rat Model of Sepsis Induced by Cecal Ligation and Puncture / 中国医学科学院学报

To establish an improved animal model of sepsis induced by cecal ligation and puncture(CLP). Ninety-six male Sprague-Dawley rats were randomly divided into sham operation group(=24),intubation group(=24),CLP group(=24),and CLP+intubation group(=24).The mortality rate,abdominal cavity condition,pathological changes and pathological scores of heart,lungs,liver,and kidneys of rats in each group were observed after modeling.Blood samples were obtained from the inferior vena cava for measuring the whole blood cells(WBC)and platelets(PLT)counts and analyzing serum interleukin(IL)-6,tumor necrosis factor(TNF)-α,serum troponin T(cTnT),creatine kinase-MB(CK-MB),alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),creatinine(CREA),and blood urea nitrogen(BUN)levels.Blood gas analysis of the aorta was also performed. The mortality rates 24 h after modeling were 0 in sham operation group and intubation group,20.8% in CLP group,and 54.2% in CLP+intubation group.Pathologically,swelling and inflammatory cell infiltration in the heart,lungs,liver,and kidneys were seen in the CLP+intubation group,inflammatory cell infiltration in a single organ was seen in most rats in the CLP group,and no obvious swelling and infiltration of inflammatory cells was observed in the sham-operation group and intubation group.The myocardial histopathology score,lung tissue injury pathology score,and kidney tissue injury pathology score in both the sham-operation group and the intubation group were significantly lower than those in the CLP group and the CLP+intubation group(all =0.000).TNF-α,PaO,CK-MB,cTnT,AST,TBIL,BUN,and CREA were significantly different between sham-operation group and intubation group/CLP group/CLP+intubation group and between intubation group and CLP group/CLP+intubation group(all =0.000).The pH level was significantly different between sham operation group and intubation group/CLP group,between intubation group and CLP group/CLP+intubate group(all =0.000). Although both CLP and CLP+intubation can well mimic the pathophysiological mechanism of sepsis in rats,multiple organ dysfunction occurs in the latter.Thus,CLP+intubation can establish animal models of multiple organ dysfunction caused by sepsis induced by clinically effective abdominal infection.

Forensic Analysis of 72 Cases with Multiple Organ Dysfunction Syndrome Caused by Traffic Accidents / 法医学杂志

Objective To investigate the epidemiological and forensic characteristics of multiple organ dysfunction syndrome （MODS） after severe trauma and explore the reference indexes for determining traumatic MODS. Methods In terms of the number of organs or systems involved in MODS, the number of failures of each organ or system, the first failing organ and the survival time after organ failure, 72 cases of MODS death caused by traffic accidents were retrospectively analyzed. The cases were divided into two groups according to the mean injury severity score （ISS）. The t test was used to analyze the differences in the number of organs or systems involved in MODS in the two groups. Chi-square test was used to analyze the differences in the types of first failing organs and the differences between the two groups in the number of cases of organ or system failure involved in MODS. Wilcoxon signed-rank test was used to analyze the differences between the two groups in survival time of MODS after trauma. Kaplan-Meier survival curve was drawn and Log-Rank test was performed. Results The number of MODS involved organs or systems after trauma in ISS≤35 group was 3-5, and 2-4 in the ISS>35 group （P<0.05）. The cases of MODS organ or system failure after trauma occurred more in brain and lung in the two groups. The first failing organ after trauma was mainly the lung or kidney. The median time of first organ failure after trauma was 2.00 d, the median survival time of MODS after trauma in ISS≤35 group was 6.00 d, and 2.33 d in ISS>35 group （P<0.05）. The survival curve of ISS≤35 group was relatively high and declined gradually, while the survival curve of ISS>35 group was relatively low and the decline was steep （P<0.05）. Conclusion The epidemiological and forensic characteristics of MODS caused by traffic accidents have certain specificity. The ISS and the forensic characteristics of MODS at ISS>35 can be used as reliable reference indexes for evaluation of the causal relationship among trauma, MODS and death.

Research progress of parenteral nutrition associated liver damage in multiple organ dysfunction syndrome / 中国综合临床

Multiple organ dysfunction syndrome (MODS) patients or intestinal failure due to infection and other factors,intestinal dysfunction can not complete the absorption of nutrients and electrolytes.Progressive malnutrition in severe patients usually develops rapidly.Early parenteral nutrition can significantly improve the prognosis of MODS patients.PN is now widely used in all kinds of severe patients,but parenteral nutrition-associated liver disease (PNALD) caused by parenteral nutrition is prevalent in such patients.The emergence of PNALD increases the difficulty of curing patients' diseases.Many studies have found thatω-3fish oil fat emulsion in nutrient solution is an effective way to prevent and improve PNALD.

Analysis of the clinical characteristics of pheochromocytoma crisis / 中华内分泌外科杂志

Objective@#To analyze the clinical characteristics of pheochromocytoma crisis (PCC) .@*Methods@#Data of 123 cases of pheochromocytoma and paraganglioma (PPGL) admitted from Apr. 2011 to Feb. 2017 were retrospectively analyzed and they were divided into crisis group and noncrisis group according to the patients with or without haemodynamic instability and end-organ damage. The differences of demographics characteristics, presentations, laboratory tests, imaging findings, perioperative clinical conditions and pathological features were compared between the two groups.@*Results@#①16 cases were enrolled into crisis group, among whom 5 were misdiagnosed, while 107 cases were enrolled into noncrisis group. ②Compared with noncrisis group, the incidence of headache, palpitation, sweating, the classic triad, other presentations of PPGL, severe hypertension and hypotension were higher, and more patients had paroxysmal hypertension and admitted to our hospital for paroxysmal presentations in crisis group (P<0.05) . ③Leukocyte, fasting blood glucose, liver transaminases, troponin and D-dimmer were higher, while estimated glomerular filtration rate (eGFR) was lower, more tumors located in the left of adrenal in crisis group (P<0.05) . ④ Patients in crisis group had higher plasma free metanephrines (MNs) , larger maximal tumor diameter, higher enhanced CT value in each period, more benign tumors and hemorrhage or necrosis in the tumors, but all the differences were not significant when compared with the noncrisis group. ⑤Patients in crisis group were more likely to undergo elective surgery. However, there was no difference in the preoperative time of α-blockade, type of surgery, intraoperative and postoperative complications, mortality among the two groups.@*Conclusions@#PCC is a rare endocrinological emergency with a highly variable manifestations, which commonly presents with typical triad, with higher incidence of hemodynamic instability and end-organ damage. Although biochemical and imaging examinations are relatively effective in the diagnosis of PCC, the misdiagnosis remains inappropriate high. Once the diagnosis is established, clinicians should timely start drug preparation while surgical resection is the key to the treatment of PCC.

Mechanism of immune inflammation after severe trauma and progress in clinical intervention / 中华创伤杂志

The pathophysiological process of immune inflammatory response after severe trauma is extremely complex, especially manifested in the dynamic changes. In the physiological response state, the inflammatory and anti-inflammatory conditions are in a dynamic balance. The immune inflammatory response is relatively stable, avoiding excessive inflammatory reactions or immunosuppression and reducing further damage to the body. In the pathological response state, the dynamic balance between inflammatory and anti-inflammatory is broken, and it can also lead to persistent inflammatory-immunosuppression-catabolism syndrome (PICS). As a result, it increases serious complications such as uncontrolled inflammatory reactions, sepsis, multiple organ dysfunction syndrome (MODS), and multiple organ failure (MOF). Current researches on post-traumatic immune inflammatory response have also expanded to the genetic level, indicating that the over-expression of genes and the generation and increase of immune response media are likely to be the key reasons for the disorder of immune inflammatory response. The author reviews the research progress of immune inflammatory response mechanism and related clinical intervention after severe trauma, in order to summarize the previous research results and explore the future research direction.

Meth-ods Data of 123 cases of pheochromocytoma and paraganglioma (PPGL) admitted from Apr. 2011 to Feb. 2017 were retrospectively analyzed and they were divided into crisis group and noncrisis group according to the pa-tients with or without haemodynamic instability and end-organ damage. The differences of demographics charac-teristics, presentations, laboratory tests, imaging findings, perioperative clinical conditions and pathological fea-tures were compared between the two groups. Results ①16 cases were enrolled into crisis group, among whom 5 were misdiagnosed, while 107 cases were enrolled into noncrisis group. ②Compared with noncrisis group, the incidence of headache, palpitation, sweating, the classic triad, other presentations of PPGL, severe hypertension and hypotension were higher, and more patients had paroxysmal hypertension and admitted to our hospital for paroxysmal presentations in crisis group (P<0.05). ③Leukocyte, fasting blood glucose, liver transaminases, tro-ponin and D-dimmer were higher, while estimated glomerular filtration rate(eGFR) was lower, more tumors locat-ed in the left of adrenal in crisis group(P<0.05). ④ Patients in crisis group had higher plasma free metanephrines (MNs), larger maximal tumor diameter, higher enhanced CT value in each period, more benign tumors and hem-orrhage or necrosis in the tumors, but all the differences were not significant when compared with the noncrisis group. ⑤Patients in crisis group were more likely to undergo elective surgery. However, there was no difference in the preoperative time of α-blockade, type of surgery, intraoperative and postoperative complications, mortality a-mong the two groups. Conclusions PCC is a rare endocrinological emergency with a highly variable manifesta-tions, which commonly presents with typical triad, with higher incidence of hemodynamic instability and end-organ damage. Although biochemical and imaging examinations are relatively effective in the diagnosis of PCC, the mis-diagnosis remains inappropriate high. Once the diagnosis is established, clinicians should timely start drug prepa-ration while surgical resection is the key to the treatment of PCC.
