Endoscopic ultrasound-guided choledochoduodenostomy versus hepaticogastrostomy combined with gastroenterostomy in malignant double obstruction (CABRIOLET_Pro): A prospective comparative study.

Objectives: Malignant double obstruction, defined as the simultaneous presence of biliary and gastric outlet obstruction, represents a challenging clinical scenario. Previous retrospective experiences have demonstrated shorter dysfunction-free survival (DyFS) of endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) versus EUS-hepaticogastrostomy (EUS-HGS) in this setting, but no prospective evidence is available. Methods: Twenty consecutive patients with malignant double obstruction, treated with EUS-gastroenterostomy (and EUS-guided biliary drainage, following a previously failed ERCP, were enrolled in a prospective observational study (ClinicalTrials.gov NCT04813055) comparing EUS-CDS versus EUS-HGS. Efficacy and safety were evaluated, with Biliary Dysfunctions as the primary outcome and DyFS using Kaplan-Meier estimates as a primary measure. Results: Twenty patients (75% with pancreatic cancer, 50% with metastatic disease) with EUS-gastroenterostomy were included (seven EUS-CDS and 13 EUS-HGS). No significant difference was detected at baseline. Technical success was 100% in both groups. EUS-CDS compared to EUS-HGS showed similar clinical success (100% vs. 92.3%, p = 0.5), a higher rate of post-procedural adverse events (42.9% vs. 7.7%, p = 0.067, mostly related to severe/fatal cholangitis in the EUS-CDS group) and a higher rate of biliary dysfunctions during follow-up (71.4% vs. 16.7%, p = 0.002).DyFS was significantly shorter in the EUS-CDS group (39 [15-62] vs. 268 [192-344] days, p = 0.0023), with a 30-days DyFS probability of 57.1% vs. 100% (hazard ratio = 7.8 [1.4-44.2]). Conclusions: In this prospective comparison of patients with malignant double obstruction undergoing EUS-gastroenterostomy, treating jaundice with EUS-CDS versus EUS-HGS resulted in a reduced probability of survival without biliary events and an increased risk of biliary dysfunctions (number needed to harm = 1.8), with detection of severe/fatal cholangitis.

A rare case report of hemolysis in a newborn: hereditary elliptocytosis.

Introduction: Hereditary Elliptocytosis (HE) comprises clinically and genetically heterogeneous red cell membranopathies resulting from defects in the horizontal linkage between red blood cell (RBC) membrane and cytoskeletal proteins, which affect mechanical stability and deformability, thereby reducing RBC lifespan. The principal defect in HE is due to dysfunction or deficiency of RBC cytoskeletal proteins. Case description: This study reported a case of severe hemolysis occurring within one day after birth in a term newborn. High-throughput sequencing was used to characterize the pathogenic gene variation in this child and to study the correlation between the identified variation and its corresponding phenotypic characteristics. Conclusion: HE is caused by monoallelic mutations, which justify the phenotypic heterogeneity observed in patients. Furthermore, molecular analysis using high-throughput sequencing enables diagnosis in disorders with highly variable heterogeneity. HE can also present with severe hemolysis during the neonatal period.

Maternal Perspectives on and Preferences for an Enhanced Neonatal Jaundice Education Program: An Evaluation Using the Consolidated Framework for Implementation Research.

Introduction: Neonatal mortality is a major contributor to under-five deaths yet the main causes of these deaths are preventable. Postnatal health education programs can improve timely detection and care seeking for newborn morbidities such as neonatal jaundice (NNJ). Being a common occurrence in low-income countries, it is surprising that women do not have sufficient knowledge about NNJ. Although the knowledge can be improved through routine education programs, healthcare providers rarely engage women in evaluating such programs, which limits their uptake and sustainability. Methods: This was a qualitative study evaluating a postnatal neonatal jaundice health education program conducted at Jinja Regional Referral Hospital (JRRH). Narrative data on the structure, design, and delivery of the program was recorded from 12 postnatal women through unstructured interviews. The participants were those who had taken part in an enhanced NNJ education program. Qualitative content analysis, guided by the Consolidated Framework for Implementation Research (CFIR) was performed. Results: Using the CFIR, two themes were identified; the intervention characteristics domain and the individual domains. The constructs under these domains were intervention design quality and packaging, relative advantage, and maternal knowledge needs. The augmented nature of the intervention, sorting individual needs, ability to promote continuity of care, and care-seeking were identified as key facilitators. Lack of group interaction was identified by some women as a possible barrier. Conclusion: Overall, the education program was positively perceived by women and preferred compared to the conventional method of health education. In low-resource settings where maternal health education can contribute to a reduction in newborn mortality, the design, implementation, and evaluation of maternal education programs should be informed by women's preferences. Healthcare providers should utilize multiple sources of information and routinely practice patient-centered evaluation to meet the changing knowledge demands of postnatal women.

Neonatal/perinatal diagnosis of hemolysis using ETCOc.

Hemolysis is a pathological shortening of the red blood cell lifespan. When hemolysis occurs in a neonate, hazardous hyperbilirubinemia and severe anemia could result. Hemolysis can be diagnosed, and its severity quantified, by the non-invasive measurement of carbon monoxide (CO) in exhaled breath. The point-of-care measurement is called "End-tidal CO corrected for ambient CO" (ETCOc). Herein we explain how ETCOc measurements can be used to diagnose and manage various perinatal/neonatal hemolytic disorders. We provide information regarding five clinical situations; 1) facilitating a precise diagnosis among neonates presenting with anemia or jaundice of unknown etiology, 2) monitoring fetal hemolysis with serial measurements of mothers during pregnancy, 3) measuring the duration of hemolysis in neonates with hemolytic disease, 4) measuring neonates who require phototherapy, to determine whether they have hemolytic vs. non-hemolytic jaundice, and 5) measuring all neonates in the birth hospital as part of a jaundice-detection and management program.

Natural course and outcomes of children with ubiquitin-specific protease 53 (USP53)-related genetic chronic cholestasis.

Ubiquitin-specific protease 53 (USP53) is essential for formation of cellular tight junctions and variations in this gene disrupt the tight junctions, resulting in cholestasis. We describe the clinical manifestations and outcomes of patients with USP53 mutations from the Indian progressive familial intrahepatic cholestasis registry. All 29 patients who harbored mutations in the USP53 gene either in the homozygous, compound heterozygous, or heterozygous state and presented with cholestasis were included. USP53 variants related to cholestasis had good outcomes, with native liver survival in 82.7%, whereas 17.3% required liver transplantation. Jaundice developed in 93% and within 3 months of age in 48.8%. Jaundice resolved in 21 (72.4%). Pruritus 76% at a median age of 7 months (severe in 10/22, 45% and refractory to medical therapy in 4, 18.1%). Majority of them (82.7%) had biallelic mutations. Protein-truncating mutations were present in 20 (69%) and missense mutations in 9 (31%). No correlation was found between the genotype and the outcome.

Assessment of neonatal glycaemic status and comorbidities in infants of diabetic mothers admitted to the neonatal care unit of Al-Ramadi Teaching Hospital for maternity and childhood, Iraq.

OBJECTIVE: To assess neonatal and maternal characteristics, glycaemic status and comorbidities in the neonates of diabetic mothers. METHODS: The cross-sectional study was conducted from October 2021 to May 2022 at the Department of Physiology, College of Medicine, University of Mustansiriyah, Baghdad, Iraq, and comprised healthy women. Samples were raised by simple random technique. Digital pulse waves were captured using a fingertip pulse wave transducer. Lab Chart Pro version 7.2 was used to automatically detect and quantify the amplitude of A, B, C, D and E waves expressed by the second derivative. QT interval of each beat was recorded by electrocardiogram, and was calculated automatically via Lab chart Pro version 7.2 without averaging. Data was spread out on Microsoft Office Excel 2013 and analysed using SPSS version 26. RESULTS: Among the 70 mothers, aged between 18 to 44 years, gestational diabetes was the commonest type 52(74.3%), and, among the 70 neonates, 52(74.3%) developed mild hypoglycaemia, 12(17.1%) hypocalcaemia, 26(37.1%) congenital heart disease, 50(71.4%) respiratory distress syndrome, 24(34.3%) hyperbilirubinaemia, 2(2.9%) congenital anomalies, 6(8.6%) prematurity, and 4(5.7%) developed birth asphyxia. Prematurity, female gender and low birthweight were significantly associated with hypoglycaemia (p<0.05). No significant differences were detected in terms of neonatal complications between pregestational and gestational diabetic mothers (p>0.05). CONCLUSIONS: Diabetic pregnancies were linked to a higher risk of neonatal complications.

Neonatal Jaundice: A Study of the Incidence in Children of Rh (D) Negative and 0 Rh (D) Positive Mothers.

Despite advances in neonatal care, neonatal jaundice remains a common problem in maternity wards. The present retrospective epidemiological study collected data on a sample of 710 newborns and compared the incidence of neonatal jaundice in infants born to Rh (D) negative and 0 Rh (D) positive mothers. The primary aim was to determine whether the higher incidence of maternal alloimmunisation in newborns was causally related to a potentially higher incidence of neonatal jaundice in newborns of 0 Rh (D) positive mothers. To the end, we investigated a possible association between the incidence of neonatal jaundice in 0 Rh (D) positive mothers and the neonatal blood group. The incidence of neonatal jaundice was not found to differ between maternal blood groups. We discuss new preventive measures that may reduce the incidence of neonatal jaundice and thereby reduce the length of hospital stay.

Sump Syndrome: The Forgotten Cause of Painless Jaundice in the Elderly.

Painless jaundice is a common presentation of abdominal malignancy seen in elderly patients. While malignancy may be a common cause of obstructive jaundice in that population group, anchor bias should always be avoided. We present a case of an elderly woman who presented with painless jaundice and weight loss. She had a very remote history of cholecystitis. She was found to have Sump syndrome due to a stricture at the Choledochoduodenostomy (CDD) site. She underwent endoscopic retrograde cholangiopancreatography (ERCP) with stent placement which shortly led to resolution of her jaundice. Biopsy from the stricture site came back negative for malignancy.

Identification of COVID-19-Associated Hepatitis in Children as an Emerging Complication in the Wake of SARS-CoV-2 Infections: Ambispective Observational Study.

Background: Although the pediatric population has largely remained free of severe COVID-19 symptoms, in some cases, SARS-CoV-2 infection has been associated with complications such as multiple inflammatory syndrome in children (MIS-C). We identified another a unique form of hepatitis occurring subsequent to asymptomatic SARS-CoV-2 infection, designated by us as COVID-19-associated hepatitis in children (CAH-C), in a subset of children who presented with hepatitis. Objective: Our study describes the clinical presentations, temporal association, and viral parameters of the CAH-C cases and compares them to those of MIS-C cases or other known forms of hepatitis in children. Methods: In an ambispective (retrospective and follow-up) observational study, records from April to July 2021 were reviewed for all children aged ≤14 years who were previously healthy and presented with a sudden onset of hepatitis, elevated transaminases, and nonobstructive jaundice. After performing all routine tests, those lacking marked inflammatory responses and without evidence of (1) other known causes of acute hepatitis or previous underlying liver disease and (2) multisystem involvement were classified as having CAH-C. Their characteristics were compared to those of children with MIS-C or other known forms of hepatitis. Results: Among the 5539 children tested for SARS-CoV-2, a total of 475 (8.6%) tested positive and 47 (0.8%) presented with hepatitis. Among the 47 children with hepatitis, 37 (79%) had features of CAH-C: having symptoms of hepatitis only, without protracted illness (mean length of stay 5 d), and an uneventful recovery following supportive treatment. In contrast, the remaining 10 (21%) had features of MIS-C-associated hepatitis: multiple system involvement; protracted illness (mean length of stay 8 d); and requiring admission to critical care, with a mortality rate of 30% (3/10). Conclusions: Our data suggest that CAH-C might be one of the new clinical complications associated with the emergence of newer variants of concern of SARS-CoV-2, which often result in changing presentations. Our findings should facilitate its early identification and thorough workup and aid its differentiation from other emerging syndromes in children, which would help initiate appropriate measures, enable better resource prioritization, and thus limit adversities.

Hydrops Gallbladder Caused by Cystic Duct Fibrosis Leading to Mirizzi Syndrome: A Case Report.

Mirizzi syndrome (MS) is a rare complication of cholelithiasis, resulting from the extrinsic compression of the common hepatic duct or common bile duct by impacted gallstones in the cystic duct or Hartmann's pouch. MS is most commonly observed in the elderly with a long-standing history of gallstones. We present the case of MS type I diagnosed following magnetic resonance cholangiopancreatography (MRCP). Surgical management was performed with laparoscopic cholecystectomy. MS should be considered as a differential diagnosis in elderly patients presenting with asymptomatic obstructive jaundice. Imaging studies such as MRCP and endoscopic retrograde cholangiopancreatography (ERCP) are essential for diagnosing. We present this case to highlight the importance of recognizing hydrops gallbladder caused by cystic duct fibrosis leading to MS.

Endoscopic ultrasound-guided biliary drainage after failed endoscopic retrograde cholangiopancreatography: The road is open for almighty biliopancreatic endoscopists!

Commentary on the article written and published by Peng et al, investigating the role of endoscopic ultrasound (EUS)-guided biliary drainage for palliation of malignant biliary obstruction after failed endoscopic retrograde cholangiopancreatography (ERCP). For 40 years endoscopic biliary drainage was synonymous with ERCP, and EUS was used mainly for diagnostic purposes. The advent of therapeutic EUS has revolutionized the field, especially with the development of a novel device such as electrocautery-enhanced lumen-apposing metal stents. Complete biliopancreatic endoscopists with both skills in ERCP and in interventional EUS, would be ideally suited to ensure patients the best drainage technique according to each individual situation.

The Prospect of Improving Pancreatic Cancer Diagnostic Capabilities by Implementing Blood Biomarkers: A Study of Evaluating Properties of a Single IL-8 and in Conjunction with CA19-9, CEA, and CEACAM6.

Background/Objectives: This study aims to evaluate the possible clinical application of interleukin 8 (IL-8) as a single biomarker and its capabilities in combination with carbohydrate antigen (CA19-9), carcinoembryonic antigen (CEA), and carcinoembryonic antigen cell adhesion molecule 6 (CEACAM6) as diagnostic and prognostic tools for pancreatic ductal adenocarcinoma (PDAC). Methods: A total of 170 serum samples from patients with PDAC (n = 100), chronic pancreatitis (CP) (n = 39), and healthy individuals (n = 31) were analysed. IL-8 and CEACAM6 were measured by an enzyme-linked immunosorbent assay (ELISA). CA19-9 and CEA were determined by chemiluminescent microparticle immunoassay, and bilirubin was quantified using a diazonium salt reaction. Receiver operating characteristic curve analysis, logistic regression, and Kaplan-Meier analyses were performed to evaluate the properties of a single IL-8 and in combination with other biomarkers. Results: The concentrations of IL-8 were statistically significantly higher in the PDAC group compared to the CP and control groups. Heterogeneous levels of IL-8 correlated with PDAC stages (p = 0.007). IL-8 had good and satisfactory diagnostic efficacy in differentiating PDAC from controls (0.858; p < 0.001) and patients with CP (0.696; p < 0.001), respectively. High and low expressions of IL-8 were not significantly associated with overall survival (OS) or disease-free survival (DFS). A combination of IL-8, CEACAM6, and CA19-9 reached the highest AUC values for differentiating PDAC from the control group. The best classification score between PDAC and the control group with CP patients was obtained by merging IL-8 and CA19-9 (0.894; p < 0.001). Conclusions: These results provide compelling evidence of IL-8 as a promising diagnostic biomarker. Nonetheless, due to the high complexity of PDAC, only the conjunction of IL-8, CA19-9, and CEACAM6 integrates sufficient diagnostic capabilities.

A Case of Metastatic Seminoma Mimicking a Primary Pancreatic Tumor.

Metastatic seminoma to the pancreas is exceedingly rare, with few reported cases in medical literature. We present a case of a 66-year-old male, six years post-remission from testicular seminoma, who presented with obstructive jaundice and a pancreatic mass mimicking primary malignancy. Diagnostic workup including endoscopic ultrasound-guided biopsy confirmed metastatic seminoma. He underwent successful treatment with four cycles of cisplatin and etoposide, achieving complete remission. This case underscores the diagnostic challenge of pancreatic metastases and emphasizes the role of biopsy in guiding appropriate management. Awareness of such presentations is crucial for timely intervention and improved patient outcomes.

Hidden in Plain Sight: Pancreatic and Gastric Metastases of Renal Cell Carcinoma Undetectable on Imaging.

Renal cell carcinoma (RCC) is one of the most common origins of pancreatic metastases. Pancreatic spread of RCC is often found incidentally on surveillance imaging in asymptomatic patients. We present the case of a 49-year-old male with a history of RCC who presented with acute pancreatitis. Multiple imaging studies showed no pancreatic masses, but endoscopic ultrasound with fine needle biopsy and endoscopy showed RCC metastases to the pancreas and stomach, respectively. Pancreatic metastases should be suspected in patients with RCC who present with progressive abdominal pain and biliary obstruction despite negative imaging. Endoscopy is useful for their detection.

A Rare Case of Life-Threatening Jaundice Caused by Epstein-Barr Virus Infection and Secondary Cold Agglutinin Syndrome Successfully Treated with Rituximab.

Background: Jaundice and hyperbilirubinemia are common clinical problems characterized by the presence of bile pigments in the blood and their deposition in body tissues. This clinical condition can be associated with a broad spectrum of potential benign and malignant causes, including hepatic inflammation, biliary obstruction, impaired bilirubin conjugation and bilirubin overproduction Therefore, the hyperbilirubinemia diagnostic work-up sometimes can be highly challenging and its therapeutic management can require a multidisciplinary approach. Case Report: We report on a unique case of life-threatening jaundice and hepatic failure in a 20-year-old female who presented to the emergency room with complaints of fever, constant left abdominal pain and generalized profuse fatigue. A complete and detailed medical history, multiple tests for various infection, radiologic investigations and histological tests were performed in order to clarify the etiology of that rapidly progressive clinical condition. Based on the results, the patient jaundice was caused by an Epstein-Barr virus (EBV) infection and secondary cold agglutinin syndrome. Given the rare and complex diagnosis, multiple clinical specialists were asked to carry out the best patient management. Conclusion: This rare case highlights how challenging the differential diagnosis and treatment of hyperbilirubinemia can be, presenting a unique case of life-threatening multifactorial hepatic failure treated successfully with rituximab.

Altered trace elements, antioxidant vitamin C, and malondialdehyde levels are associated with the pathophysiology and development of pre-hepatic jaundice: A case-control study.

Objectives: Pre-hepatic jaundice results from an imbalance between bilirubin production and clearance, often linked to hemoglobinopathies. Antioxidant vitamin C, malondialdehyde, and trace elements play roles in jaundice, yet their specific associations remain unclear. The objective is to assess and compare these biomarkers in pre-hepatic jaundice patients and healthy controls, aiming to identify potential diagnostic markers and understand distinctive characteristics related to the disease's pathogenesis. Methods: This case-control study enrolled 50 pre-hepatic jaundice patients and 50 healthy controls, utilizing advanced techniques for biomarker quantification. We completed blood sample collection from study participants between 1 September 2023 and 31 December 2023. This study investigates the correlation between various biomarkers and pre-hepatic jaundice using serum samples with a focus on antioxidant vitamin C, malondialdehyde, and trace elements. Results: This study demonstrates elevated concentrations of malondialdehyde in patients with pre-hepatic jaundice, suggesting alterations in bilirubin metabolism and increased oxidative stress. We found that the serum levels of malondialdehyde were significantly higher in pre-hepatic jaundice patients compared to healthy controls. Our observations revealed a notable decrease in the average serum vitamin C levels in patients with pre-hepatic jaundice compared to healthy controls. The patients had lower serum Zn levels and higher serum Cu and Mn levels compared to the healthy controls. The correlation study demonstrates robust positive correlations among these biomarkers in pre-hepatic jaundice. As the levels of vitamin C rise, the levels of the other criteria often fall, and vice versa. There is an inverse relationship between higher levels of vitamin C and lower levels of malondialdehyde. The current investigation identifies possible changes in antioxidant vitamins, malondialdehyde levels, and trace elements, which provide significant insights for targeted interventions. Conclusions: The present research highlights the integrated significance of vitamin C, malondialdehyde, and trace elements in the progression of the disease.

Evaluation of efficacy of oral calcium phosphate as an adjunct to standard-of-care regular phototherapy in cases of neonatal jaundice: a hospital-based double-blind, randomised, placebo-controlled trial.

OBJECTIVE: Neonatal jaundice is the most common cause of neonatal morbidity and rehospitalisation in the first week of life, affecting approximately 60% of term and 80% of preterm neonates, with 10% requiring phototherapy to prevent bilirubin-induced neurological dysfunction. Enterohepatic circulation contributes 10%-20% of the body's bilirubin load, and oral calcium-phosphate can inhibit this process by binding to unconjugated bilirubin and acting as a bilirubin-trapping agent in the gut. This study aimed to evaluate the efficacy of oral calcium phosphate as an adjunct to phototherapy in reducing phototherapy duration, improving bilirubin decline rate and lowering rebound hyperbilirubinaemia incidence. METHODS: This double-blind, placebo-controlled randomised controlled trial with a 1:1 allocation ratio was conducted in the neonatal intensive care unit of a tertiary care hospital in Eastern India. The investigator and the analyst were blinded to the treatment assignments. Eligible neonates with neonatal jaundice requiring phototherapy as per the 'American Academy of Pediatrics or 'National Institute for Health and Care Excellence' guidelines were enrolled and randomly assigned to receive either oral calcium phosphate or placebo. RESULTS: The total duration of phototherapy was significantly lower in the intervention group compared with placebo (18.8±5.63 hours vs 24.3±4.50 hours; mean difference=-5.55 (95% CI -7.82 to -3.28), p<0.001). The rate of fall of bilirubin (mg/dL/hour) was also significantly higher in the intervention group (0.186±0.0137 vs 0.116±0.0088; mean difference=0.0693 (95% CI 0.0642 to 0.0745), p<0.001). The intervention group showed a trend towards a decrease in the incidence of rebound hyperbilirubinaemia, with a relative risk of 0.30 ((95% CI 0.0891 to 1.01), p=0.066). CONCLUSION: The use of oral calcium phosphate results in a statistically significant reduction in phototherapy hours, an improvement in the rate of bilirubin decline and a decrease in rebound hyperbilirubinaemia incidence. This allows for shorter hospital stays and reduces the need for rehospitalisation, resulting in less mother-baby dyad separation, lower hospital resource consumption and reduced financial burden on parents.

A retrospective comparative study of biliary drainage using balloon endoscopy and endoscopic ultrasound for malignant obstruction in patients with surgically altered anatomy.

BACKGROUND AND AIMS: Endoscopic biliary drainage for malignant biliary obstruction (MBO) in patients with surgically altered anatomy is challenging, and technical difficulty could differ by the anatomy. Balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) and endoscopic ultrasonography-guided biliary drainage (EUS-BD) are both emerging procedures, and we conducted the single-center, retrospective study to compare clinical outcomes of BE-ERCP and EUS-BD for MBO. METHODS: Consecutive patients with surgically altered anatomy who underwent BE-ERCP or EUS-BD for MBO were retrospectively studies. Technical and clinical success rates, adverse events (AEs), and time to recurrent biliary obstruction (TRBO) were compared. RESULTS: Patient characteristics were comparable between BE-ERCP (n = 118) and EUS-BD (n = 32), other than more patients with hepaticojejunostomy in the BE-ERCP group (66% vs. 44%, P = 0.03). Technical success rate was significantly higher in the EUS-BD group (70% vs. 94%, P = 0.005), but clinical success rates (84% vs. 90%, P = 0.55), early AE (14% vs. 22%, P = 0.29) and late AE rates (42% vs. 38%, P = 0.84), and RBO rates (31% vs. 34%, P = 0.67) were comparable between the groups. TRBO was 170 and 206 days in the BE-ERCP and EUS-BD group (P = 0.37). In the subgroup analysis of patients with the intact papilla, the technical success rate of BE-ERCP was as low as 55%, compared to 94% in EUS-BD (P = 0.003). CONCLUSION: EUS-BD was associated with higher technical success rate than BE-ERCP for MBO in patients with surgically altered anatomy.

Malaria in Appalachia? A Rare Case of Plasmodium vivax in an Adolescent Exchange Student From South Korea.

Cultural globalization, including the resumption of international travel post-SARS-CoV-2 pandemic, emphasizes the importance of regional infectious disease variation, especially when considering a differential diagnosis for fever in a traveler. Prompt diagnosis is often imperative to initiate proper treatment and reduce morbidity and mortality associated with many environmental and vector-borne pathogens. The Anopheles mosquito transmits malaria in areas endemic to malaria. Malaria, while not endemic to the United States, can be seen in a traveler. This illness can be deadly if left untreated. Symptoms of malaria include but are not limited to jaundice, cyclic fever, and flu-like illness. In this case report, we describe a unique presentation of Plasmodium vivax malaria in a 17-year-old traveler from South Korea with a negative rapid malaria test. A peripheral smear from microscopy demonstrated the presence of gametocytes, which are pathognomonic for malaria. Despite the presence of a very low parasitemia (<1%), the patient was noted to have some severe features such as significant thrombocytopenia, acute kidney injury, as well as relapsed disease several months later despite adequate treatment. A high clinical index of suspicion and a detailed history allowed prompt treatment and no permanent sequelae.
