ABSTRACT
OBJECTIVE: Disorders of gut-brain interaction may arise after acute gastroenteritis. Data on the influence of pathogen type on the risk of postinfection IBS (PI-IBS), as on postinfection functional dyspepsia (PI-FD), are limited. We conducted a systematic review and meta-analysis to determine prevalence of PI-IBS or PI-FD after acute gastroenteritis. DESIGN: We included observational studies recruiting ≥50 adults and reporting prevalence of IBS or FD after acute gastroenteritis with ≥3-month follow-up. A random effects model was used to estimate prevalence and ORs with 95% CIs. RESULTS: In total, 47 studies (28 170 subjects) were eligible. Overall prevalence of PI-IBS and PI-FD were 14.5% and 12.7%, respectively. IBS persisted in 39.8% of subjects in the long-term (>5 years follow-up) after diagnosis. Individuals experiencing acute gastroenteritis had a significantly higher odds of IBS (OR 4.3) and FD (OR 3.0) than non-exposed controls. PI-IBS was most associated with parasites (prevalence 30.1%), but in only two studies, followed by bacteria (18.3%) and viruses (10.7%). In available studies, Campylobacter was associated with the highest PI-IBS prevalence (20.7%) whereas Proteobacteria and SARS-CoV-2 yielded the highest odds for PI-IBS (both OR 5.4). Prevalence of PI-FD was 10.0% for SARS-CoV-2 and 13.6% for bacteria (Enterobacteriaceae 19.4%). CONCLUSION: In a large systematic review and meta-analysis, 14.5% of individuals experiencing acute gastroenteritis developed PI-IBS and 12.7% PI-FD, with greater than fourfold increased odds for IBS and threefold for FD. Proinflammatory microbes, including Proteobacteria and subcategories, and SARS-CoV-2, may be associated with the development of PI-IBS and PI-FD.

Neuromyelitis optica spectrum of disorders is a rare cause of optic neuritis in children. It is a critical diagnosis requiring urgent management, with delays carrying both life- and sight-threatening complications. Most of the published literature on this entity is in adult patients, with only a few case reports to guide management in the paediatric population. The purpose of this article is to shareour experience in the management of this condition in a child, and thus hopefully add to the limited body of knowledge currently available.

BACKGROUND: The incidence of dysnatremia in children with acute gastritis/gastroenteritis varies, and factors associated with either dysnatremia or hyponatremia at presentation have not been identified clearly. METHODS: This retrospective study included patients aged 1 month to 18 years hospitalized for community-acquired acute gastritis/gastroenteritis from January to October 2016. Factors associated with dysnatremia at presentation were identified using multivariable analysis. RESULTS: Among the 304 children included, the median age was 2.2 (1.0, 4.2) years. The incidence of dysnatremia at presentation was 17.1% (hyponatremia 15.8%; hypernatremia 1.3%). Patients who had moderate (p = 0.03) and severe dehydration (p = 0.04) and presented with vomiting and diarrhea simultaneously (p = 0.03) were associated with dysnatremia at presentation. Patients presented with vomiting and diarrhea simultaneously was associated with hyponatremia at presentation (p = 0.02). CONCLUSIONS: Dysnatremia was common in children with acute gastritis/gastroenteritis. Moderate to severe dehydration and the presence of vomiting and diarrhea simultanously were significantly associated with dysnatremia at presentation. Furthermore, presenting with vomiting and diarrhea silmutaneously was associated with hyponatremia at presentation. Serum electrolytes should be monitored in patients with those conditions.

INTRODUCTION: The multifactorial etiology of gastroenteritis emphasizes the need for different laboratory methods to identify or exclude infectious agents and evaluate the severity of diarrheal disease. OBJECTIVE: To diagnose the infectious etiology in diarrheic children and to evaluate some fecal markers associated with intestinal integrity. MATERIALS AND METHODS: The study group comprised 45 children with diarrheal disease, tested for enteropathogens and malabsorption markers, and 76 children whose feces were used for fat evaluation by the traditional and acid steatocrit tests. RESULTS: We observed acute diarrhea in 80% of the children and persistent diarrhea in 20%. Of the diarrheic individuals analyzed, 40% were positive for enteropathogens, with rotavirus (13.3%) and Giardia duodenalis (11.1%) the most frequently diagnosed. Among the infected patients, occult blood was more evident in those carrying pathogenic bacteria (40%) and enteroviruses (40%), while steatorrhea was observed in infections by the protozoa G. duodenalis (35.7%). Children with diarrhea excreted significantly more lipids in feces than non-diarrheic children, as determined by the traditional (p<0.0003) and acid steatocrit (p<0.0001) methods. Moreover, the acid steatocrit method detected 16.7% more fecal fat than the traditional method. CONCLUSIONS: Childhood diarrhea can lead to increasingly severe nutrient deficiencies. Steatorrhea is the hallmark of malabsorption, and a stool test, such as the acid steatocrit, can be routinely used as a laboratory tool for the semi-quantitative evaluation of fat malabsorption in diarrheic children.
Introducción. La etiología multifactorial de la gastroenteritis enfatiza la necesidad de usar diferentes métodos de laboratorio para identificar o excluir agentes infecciosos y evaluar la gravedad de la enfermedad diarreica. Objetivo. Diagnosticar la etiología infecciosa de la diarrea en niños y evaluar algunos marcadores fecales asociados con la integridad intestinal. Materiales y métodos. Se estudiaron 45 niños con enfermedad diarreica, en los cuales se evaluaron la presencia de enteropatógenos y los marcadores de malabsorción. Se analizaron las muestras fecales de 76 niños, mediante las pruebas de esteatocrito tradicional y esteatocrito ácido, para la cuantificación de la grasa. Resultados. Se observó diarrea aguda en el 80 % de los niños y diarrea persistente en el 20 %. De los individuos con diarrea, el 40 % fue positivo para enteropatógenos; los más diagnosticados fueron rotavirus (13,3 %) y Giardia duodenalis (11,1 %). Entre los pacientes infectados, la sangre oculta fue más evidente en aquellos portadores de bacterias patógenas (40 %) o enterovirus (40%), mientras que la esteatorrea se observó en infecciones por el protozoo G. duodenalis (35,7 %). Los niños con diarrea excretaron significativamente más lípidos en las heces que aquellos sin diarrea, según lo determinado por los métodos de esteatocrito tradicional (p<0,0003) y esteatocrito ácido (p<0,0001). Conclusiones. La diarrea infantil puede provocar deficiencias graves de nutrientes. La esteatorrea es distintiva de la malabsorción intestinal y puede detectarse mediante la estimación del esteatocrito ácido. Esta prueba podría utilizarse de forma rutinaria como una herramienta de laboratorio para la evaluación semicuantitativa de la malabsorción de grasas en niños con diarrea.

INTRODUCTION: Intestinal inflammation and gut microbiota dysbiosis can stimulate degeneration of dopaminergic neurons and development of Parkinson's disease (PD) via the gut-brain axis in certain patients. METHODS: In a case-control study, fecal markers of intestinal inflammation and permeability were measured using the ELISA method in PD patients and healthy controls. Motor and nonmotor symptoms were assessed using the Movement Disorder Society (MDS) Unified PD Rating Scale, Hoehn & Yahr scale, MDS Non-Motor Symptom Scale, Scales for Outcomes in PD - Autonomic Dysfunction, PD Sleep Scale - 2, Montreal Cognitive Assessment, Beck Anxiety Inventory, and Beck Depression Inventory-II. A correlation was established between the intestinal inflammation and permeability markers and PD symptoms. RESULTS: Higher levels of beta-defensin 2, zonulin and lactoferrin were recorded in PD patients compared to controls. Calprotectin and secretory immunoglobulin A showed no significant differences. Regression analysis indicated the roles of beta-defensin 2 and lactoferrin in predicting PD likelihood. Calprotectin yielded positive correlations with disease duration, depression, motor fluctuations, and gastrointestinal symptoms; beta defensin 2 with thermoregulation; and secretory immunoglobulin A with depression. Secretory immunoglobulin A showed negative correlation with age and age at disease onset, while zonulin showed negative correlation with the MDS Unified PD Rating Scale total score. CONCLUSIONS: Fecal markers differed in PD patients compared to controls and correlated with age, disease duration, and some nonmotor symptoms. Future studies should identify the subgroups of PD patients that are likely to develop intestinal inflammation.

OBJECTIVE: This study aims to investigate and analyze the risk factors of convulsions in children with rotavirus gastroenteritis and to construct a nomogram prediction model. METHODS: A retrospective analysis was performed on 940 cases of pediatric patients with rotavirus gastroenteritis treated in our hospital from December 2017 to December 2022. Based on whether convulsions occurred during hospitalization, patients were divided into the convulsion group (n = 135) and the convulsion-free group (n = 805). Clinical information of patients in both groups was collected, logistic regression analysis was carried out to analyze the convulsion risk factors pertaining to children with rotavirus gastroenteritis, and a nomogram prediction model was constructed. RESULTS: The univariate analysis revealed that fever, frequency of diarrhea, white blood cell count, blood calcium level, blood glucose level, CO 2 CP, creatine kinase myocardial band (CK-MB), and blood pH value were all factors that display statistically significant differences at the level of P = 0.05. Then, logistic regression analysis was carried out, taking the occurrence of such convulsions as the dependent variable and the aforementioned factors as independent variables. The results show that fever, frequency of diarrhea, blood calcium, CO 2 CP, and CK-MB were the independent risk factors ( P < 0.05), whereas the area under the receiver operating characteristic curve (area under the curve) of the constructed nomogram prediction model based on these factors was 0.842 (95% confidence interval, 0.821-0.914). CONCLUSIONS: Frequency of diarrhea, blood calcium, CO 2 CP, and CK-MB are independent risk factors for the occurrence of convulsions in children with rotavirus gastroenteritis. The nomogram prediction model constructed based on these risk factors provides guidance and value in effectively preventing and controlling convulsions in children with rotavirus gastroenteritis.

Fever is common among individuals seeking healthcare after traveling to tropical regions. Despite the association with potentially severe disease, the etiology is often not determined. Plasma protein patterns can be informative to understand the host response to infection and can potentially indicate the pathogen causing the disease. In this study, we measured 49 proteins in the plasma of 124 patients with fever after travel to tropical or subtropical regions. The patients had confirmed diagnoses of either malaria, dengue fever, influenza, bacterial respiratory tract infection, or bacterial gastroenteritis, representing the most common etiologies. We used multivariate and machine learning methods to identify combinations of proteins that contributed to distinguishing infected patients from healthy controls, and each other. Malaria displayed the most unique protein signature, indicating a strong immunoregulatory response with high levels of IL10, sTNFRI and II, and sCD25 but low levels of sCD40L. In contrast, bacterial gastroenteritis had high levels of sCD40L, APRIL, and IFN-γ, while dengue was the only infection with elevated IFN-α2. These results suggest that characterization of the inflammatory profile of individuals with fever can help to identify disease-specific host responses, which in turn can be used to guide future research on diagnostic strategies and therapeutic interventions.

Post-infectious irritable bowel syndrome (PI-IBS) occurs in about 10% of cases following gastroenteritis. The incidence of IBS is higher in females. However, it is not clear whether this is due to biological or psychosocial factors. We aimed to investigate the influence of gender roles on the incidence of PI-IBS, alongside traditional risk factors. Our study included 231 patients diagnosed with gastroenteritis who were hospitalized and treated with antibiotics between 2018 and 2021. The Korean Sex Role Inventory-Short Form (KSRI-SF), based on the Bem Sex Role Inventory (BSRI) was used to categorize patients (androgynous, masculine, feminine, and undifferentiated types). Six months after treatment, we conducted a telephone survey to confirm the presence of PI-IBS using the ROME IV criteria. Among the patients, 43.3% were female, and the mean age was 43.67 ± 16.09 years. After 6 months, 34 patients developed PI-IBS. Univariate analysis revealed that younger age, female sex, KSRI-SF undifferentiated type, and longer duration of antibiotic use independently influenced the occurrence of PI-IBS. Multivariate analysis showed that PI-IBS was associated with the KSRI-SF undifferentiated type and higher C-reactive protein (CRP) levels. Our study showed that the KSRI-SF undifferentiated type and high CRP levels at initial infection were associated with PI-IBS.

BACKGROUND Infectious diarrheal illnesses such as rotavirus gastroenteritis are significant contributors to childhood morbidity and mortality, especially in low socio-demographic index regions. Major advances in addressing this issue include sanitation and clean water initiatives, as well as rotavirus immunization. In Australia, a robust vaccination program has significantly reduced childhood rotavirus infections, leading to decreased hospitalizations and mortality. However, cases of adult rotavirus still occur, and although these adult patients usually do not require interventional management, it is possible for them to present critically unwell and require resuscitation. CASE REPORT A previously well 65-year-old man presented to the Emergency Department febrile and hypotensive with severe diarrhea attributed to rotavirus. Clinically, he presented with mixed hypovolemic and septic shock. Despite initial resuscitation, he had multiple severe acute end-organ complications, secondary to poor perfusion. He acquired an acute kidney injury, type-2 myocardial infarction, and ischemic hepatic injury. The mainstay of management was rapid fluid resuscitation, continuous renal replacement therapy, and monitoring in the Intensive Care Unit; however, it was crucial to empirically treat for other causes of shock. CONCLUSIONS To the best of our knowledge, there is a scarcity of reports documenting the management of severe rotavirus gastroenteritis in adults. We recommend advising elderly patients to avoid contact with individuals with diarrheal illnesses, especially rotavirus gastroenteritis. Clinicians should also promote awareness regarding the potential severity of a disease that is typically managed conservatively, and be aware that intervention can be required in severe gastroenteritis.

We report an infant case of transient distal renal tubular acidosis and Fanconi syndrome caused by rotavirus gastroenteritis. A 10-month-old boy was admitted to the hospital because of frequent vomiting, lack of vitality, and dehydration. He was diagnosed with rotavirus gastroenteritis on account of his positive stool rotavirus antigen test. Although he presented with acidemia and severe mixed metabolic acidosis, he also had a urine pH of 6.0, indicating impaired urinary acidification. Therefore, he was diagnosed with distal renal tubular acidosis. On the third day of hospitalization, a relatively low %tubular reabsorption of phosphate level with hypophosphatemia, increased fractional excretion of uric acid with hypouricemia, and high urinary ß2-microglobulin levels were observed. Moreover, he was diagnosed with Fanconi syndrome on account of multiple proximal tubular dysfunctions. After remission of rotavirus gastroenteritis, the signs of renal tubular dysfunction improved. This was a case of rotavirus gastroenteritis-caused transient distal renal tubular acidosis and Fanconi syndrome. Severe metabolic acidosis resulted from anion-gap metabolic acidosis due to acute kidney injury by rotavirus gastroenteritis and normal anion-gap acidosis due to renal tubular acidosis. When renal tubular acidosis is associated with a disease that causes anion-gap metabolic acidosis, mixed metabolic acidosis occurs and becomes exacerbated. Furthermore, it is important to consider the complications of renal tubular acidosis in the case of severe metabolic acidosis.

Acute gastroenteritis is one of the main causes of electrolyte imbalance in infants. We aimed to determine the frequency of and factors associated with dysnatremia at presentation and establish the ideal intravenous treatment scheme. The records of hospitalized infants aged 1-12 months with community-acquired acute gastroenteritis between January 2017 and March 2021 were retrospectively reviewed. Factors associated with dysnatremia at presentation were analyzed by multivariable logistic regression analysis. Subsequent sodium levels 4-24 h after intravenous fluid treatments, which were categorized into 2 groups, were determined in the subgroup of infants with normal sodium levels at presentation. A total of 347 infants with a median age of 8.0 (5.0-10.0) months were included. The frequency of dysnatremia at presentation was 14% (hyponatremia 12% and hypernatremia 2.0%). Severe dehydration was associated with dysnatremia at presentation (p = 0.048). Among 68 infants with normal sodium levels at presentation, the median sodium change was highest in the 5% dextrose in saline group, with changes of + 3 (0.5-5) and + 1 (- 2 to 2) mmol/L in infants who received 5% dextrose in saline and 5% dextrose in 1/3-1/2 saline, respectively (p = 0.001). Four out of 47 infants (8.5%) developed hyponatremia while receiving 5% dextrose in 1/3-1/2 saline. None of those who received 5% dextrose in saline developed subsequent dysnatremia. Conclusion: The frequency of dysnatremia at presentation among infants with acute gastroenteritis was 14%. Severe dehydration was associated with dysnatremia at presentation, so electrolyte levels need to be assessed in these patients. The use of isotonic solution did not promote acquired dysnatremia. This study supports once more that current guidelines recommending isotonic solution for children, and, especially, infant rehydration, are important also for infants in Thailand. What is Known: ⢠There were a wide variation in the incidence of dysnatremia at presentation in children with acute gastroenteritis in previous pediatric series. ⢠The AAP guidelines recommend using isotonic solution in children with acute illness from 28 days to 18 years of age to prevent acquired hyponatremia. What is New: ⢠The incidence of dysnatremia at presentation in infants with acute gastroenteritis was 14% (hyponatremia 12% and hypernatremia 2.0%). ⢠The use of isotonic solution did not promote acquired dysnatremia in infants with acute gastroenteritis.

Norovirus, a positive-stranded RNA virus, is one of the leading causes of acute gastroenteritis among all age groups worldwide. The neurological manifestations of norovirus are underrecognized, but several wide-spectrum neurological manifestations have been reported among infected individuals in the last few years. Our objective was to summarize the features of norovirus-associated neurological disorders based on the available literature. We used the existing PRISMA consensus statement. Data were collected from PubMed, EMBASE, Web of Science, and Scopus databases up to Jan 30, 2023, using pre-specified searching strategies. Twenty-one articles were selected for the qualitative synthesis. Among these, seven hundred and seventy-four patients with norovirus-associated neurological manifestations were reported. Most cases were seizure episodes, infection-induced encephalopathy, and immune-driven disorders. However, only a few studies have addressed the pathogenesis of norovirus-related neurological complications. The pathogenesis of these manifestations may be mediated by either neurotropism or aberrant immune-mediated injury, or both, depending on the affected system. Our review could help clinicians to recognize these neurological manifestations better and earlier while deepening the understanding of the pathogenesis of this viral infection.

INTRODUCTION: Postinfectious irritable bowel syndrome is a phenomenon that can occur following bouts of acute gastroenteritis. While bacterial pathogens are typically implicated in the development of postinfectious irritable bowel syndrome, viral and parasitic infections should also be considered as inciting pathogens. CASE PRESENTATION: An immunocompetent, 65-year-old woman presented with several weeks of watery diarrhea, which polymerase chain reaction testing confirmed to be a Cyclospora infection. Resolution of diarrhea was achieved with antibiotic treatment, however, months later she presented to the gastroenterology service with persistence of loose stools and abdominal cramping consistent with a diagnosis of postinfectious irritable bowel syndrome. DISCUSSION: Postinfectious irritable bowel syndrome has a similar presentation to sporadic irritable bowel syndrome, with diagnosis aided by the identification of an inciting pathogen. To our knowledge, this is the first documented case of Cyclospora-induced postinfectious irritable bowel syndrome. While parasitic infections typically aren't implicated in cases of postinfectious irritable bowel syndrome, this case highlights the value of considering this condition as a cause of protracted diarrhea in patients previously diagnosed with Cyclospora.

OBJECTIVE: Explore the clinical characteristics and prognosis of children with norovirus (NoV)-associated benign convulsions with mild gastroenteritis (CwG). METHODS: We retrospectively analyzed the Clinical and laboratory data of children with NoV-associated CwG admitted to the emergency department of Guangzhou Children's Hospital between January 2019 and January 2020. And patients were followed up for 23-36 months. RESULTS: There are 49 cases met the CwG criteria. Vomiting was the first symptom in 31 (63.3%) patients, and vomiting could be the main or the only gastrointestinal symptom. The mean frequency of seizures was 3.8 ± 2.4 episodes. Most patients (95.9%) experienced seizures that lasted for less than 5 min. Of the 43 (87.8%) cases followed up from 23 to 36 months, only one experienced recurrent convulsions (after rotavirus infection). SIGNIFICANCE: NoV-associated CwG patients were prone to experiencing more convulsions. However, because most NoV-associated CwG patients had good prognosis, long-term use of anticonvulsants are unnecessary.

Post-infectious irritable bowel syndrome (PI-IBS) is a particular type of IBS, with symptom onset after an acute episode of infectious gastroenteritis. Despite infectious disease resolution and clearance of the inciting pathogen agent, 10% of patients will develop PI-IBS. In susceptible individuals, the exposure to pathogenic organisms leads to a marked shift in the gut microbiota with prolonged changes in host-microbiota interactions. These changes can affect the gut-brain axis and the visceral sensitivity, disrupting the intestinal barrier, altering neuromuscular function, triggering persistent low inflammation, and sustaining the onset of IBS symptoms. There is no specific treatment strategy for PI-IBS. Different drug classes can be used to treat PI-IBS similar to patients with IBS in general, guided by their clinical symptoms. This review summarizes the current evidence for microbial dysbiosis in PI-IBS and analyzes the available data regarding the role of the microbiome in mediating the central and peripheral dysfunctions that lead to IBS symptoms. It also discusses the current state of evidence on therapies targeting the microbiome in the management of PI-IBS. The results of microbial modulation strategies used in relieving IBS symptomatology are encouraging. Several studies on PI-IBS animal models reported promising results. However, published data that describe the efficacy and safety of microbial targeted therapy in PI-IBS patients are scarce. Future research is required.

BACKGROUND: In patients with adrenal insufficiency (AI), adrenal crisis (AC) represents a clinical emergency. Early recognition and prompt management of AC or AC-risk conditions in the Emergency Department (ED) can reduce critical episodes and AC-related outcomes. The aim of the study is to report the clinical and biochemical characteristics of AC presentation to improve their timely recognition and proper management in a ED setting. METHODS: Single-centre, retrospective, observational study on pediatric patients followed at the Department of Pediatric Endocrinology of Regina Margherita Children's Hospital of Turin for primary AI (PAI) and central AI (CAI). RESULTS: Among the 89 children followed for AI (44 PAI, 45 CAI), 35 patients (21 PAI, 14 CAI) referred to the PED, for a total of 77 accesses (44 in patients with PAI and 33 with CAI). The main causes of admission to the PED were gastroenteritis (59.7%), fever, hyporexia or asthenia (45.5%), neurological signs and respiratory disorders (33.8%). The mean sodium value at PED admission was 137.2 ± 1.23 mmol/l and 133.3 ± 1.46 mmol/l in PAI and CAI, respectively (p = 0.05). Steroids administration in PED was faster in patients with CAI than in those with PAI (2.75 ± 0.61 and 3.09 ± 1.47 h from PED access, p = 0.83). Significant factors related to the development of AC were signs of dehydration at admission (p = 0.027) and lack of intake or increase of usual steroid therapy at home (p = 0.059). Endocrinological consulting was requested in 69.2% of patients with AC and 48.4% of subjects without AC (p = 0.032). CONCLUSION: children with AI may refer to the PED with an acute life-threatening condition that needs prompt recognition and management. These preliminary data indicate how critical the education of children and families with AI is to improve the management at home, and how fundamental the collaboration of the pediatric endocrinologist with all PED personnel is in raising awareness of early symptoms and signs of AC to anticipate the proper treatment and prevent or reduce the correlated serious events.

Eosinophilic inflammation of the digestive tract is an inflammatory disease characterized by extensive infiltration of eosinophils into the gastrointestinal tract. It can be either a primary disorder of the digestive tract or be secondary to another cause of tissue eosinophilia. Primary disorders include eosinophilic esophagitis (OE) and eosinophilic gastroenteritis (GEEo). These are 2 rare pathologies considered to be diseases related to a Th2-mediated food allergy. The role of the pathologist is twofold: (1) he must make the diagnosis of tissue esosinophilia and propose the various causes, knowing that a secondary cause is the most frequently observed; (2) identify the abnormal number of polymorphonuclear eosinophils, which implies knowing the normal distribution of eosinophils in the different digestive segments. To carry the diagnosis of EO, the threshold of polymorphonuclear eosinophils must be ≥ 15/fields × 400. There is no predefined threshold concerning the other segments of the digestive tract to carry the diagnosis of GEEO. In addition, to make the diagnosis of primary digestive tissue eosinophilia, the patient must be symptomatic with histological evidence of eosinophilia and have ruled out all secondary causes. The main differential diagnosis of OE is gastroesophageal reflux disease. The differential diagnoses of GEEo are multiple, including primarily drugs and parasitic infections.

OBJECTIVES: Describe characteristics of gastroenteritis, bacteremia, and meningitis caused by nontyphoidal Salmonella among US infants. METHODS: We analyze national surveillance data during 1968-2015 and active, sentinel surveillance data during 1996-2015 for culture-confirmed Salmonella infections by syndrome, year, serotype, age, and race. RESULTS: During 1968-2015, 190 627 culture-confirmed Salmonella infections among infants were reported, including 165 236 (86.7%) cases of gastroenteritis, 6767 (3.5%) bacteremia, 371 (0.2%) meningitis, and 18 253 (9.7%) with other or unknown specimen sources. Incidence increased during the late 1970s-1980s, declined during the 1990s-early 2000s, and has gradually increased since the mid-2000s. Infants' median age was 4 months for gastroenteritis and bacteremia and 2 months for meningitis. The most frequently reported serotypes were Typhimurium (35 468; 22%) for gastroenteritis and Heidelberg for bacteremia (1954; 29%) and meningitis (65; 18%). During 1996-2015 in sentinel site surveillance, median annual incidence of gastroenteritis was 120, bacteremia 6.2, and meningitis 0.25 per 100 000 infants. Boys had a higher incidence of each syndrome than girls in both surveillance systems, but most differences were not statistically significant. Overall, hospitalization and fatality rates were 26% and 0.1% for gastroenteritis, 70% and 1.6% for bacteremia, and 96% and 4% for meningitis. During 2004-2015, invasive salmonellosis incidence was higher for Black (incident rate ratio, 2.7; 95% confidence interval, 2.6-2.8) and Asian (incident rate ratio, 1.8; 95% confidence interval, 1.7-1.8) than white infants. CONCLUSIONS: Salmonellosis causes substantial infant morbidity and mortality; serotype heidelberg caused the most invasive infections.

Congenital Adrenal Hyperplasia is a group of autosomal recessive diseases due to deficiencies of enzymes involved in steroidogenesis. If not diagnosed and treated adequately, Congenital Adrenal Hyperplasia can lead to an acute adrenal crisis with hemodynamic collapse. Acute stressors and steroid insufficiency precipitate an adrenal crisis. The major clinical features are hypotension and volume depletion. Nonspecific symptoms such as fatigue, lack of energy, anorexia, nausea, vomiting, and abdominal pain are common. We report a case of a 3-year male previously diagnosed with congenital adrenal hyperplasia in adrenal crisis secondary to medicine noncompliance and gastroenteritis. The diagnosis was based on the clinical history and biochemical investigations. After initial resuscitation was managed; lifelong oral prednisolone and fludrocortisone were prescribed. Keywords: adrenal insufficiency; gastroenteritis; glucocorticoids.
