Isolated intrasplenic vascular calcifications in a child with type 1 diabetes mellitus---A case report.

We report a case of vascular calcifications in the spleen of a 7-year-old girl who was diagnosed with type 1 diabetes mellitus (DM). The possible etiology for vascular calcifications might be medial sclerosis associated with DM. To the best of our knowledge, this finding has not yet been reported in the literature. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:438-440, 2017.

Naphthalene Ball Ingestion Leading to Intravascular Hemolysis and Acute Kidney Injury.

Naphthalene is an aromatic hydrocarbon found in mothballs, deodorizers, or insecticides. Naphthalene poisoning is not commonly seen in the pediatric age group due to its pungent odor and taste, water insolubility, and poor absorption from the gastrointestinal tract (GIT). This case report describes a five-year-old boy who experienced accidental naphthalene mothball ingestion resulting in intravascular hemolysis and acute kidney injury (AKI). Naphthalene exposure can cause severe complications, especially in children. The clinical presentation included fever, abdominal pain, vomiting, decreased urine output, and hematuria. The laboratory findings revealed hemolytic anemia, elevated serum creatinine, and proteinuria. The child received supportive treatment including intravenous fluids, packed red blood cell transfusions, and hemodialysis for AKI. Early diagnosis and intervention are crucial for a favorable outcome. This case highlights the importance of considering naphthalene poisoning in the differential diagnosis of children with hemolysis and AKI.

Bridging The Gap: Essential Role of Parents and Caregivers In Their Child's Management in the Pediatric Intensive Care Unit.

The importance of parental involvement in the care and management decisions made for children hospitalized in the pediatric intensive care unit (PICU) is examined in this editorial. Initial days and weeks in a PICU can be challenging for the child and family due to the emotional intensity and medical complexity of the therapy a child receives. Regardless of the result, families may feel uncertain and anxious that their child may die or have a terrible outcome. The majority of pediatric patient deaths in hospitals happen in the PICU. Recognizing and supporting the crucial role of parents or caretakers in informed decision-making and management of their child's condition is essential for advancing prevention, detection, and treatment efforts.

Glutaric Aciduria Presenting With an Acute Encephalitic Crisis: A Case Report.

Glutaric aciduria type 1 (GA1) is an organic aciduria inherited in an autosomal recessive pattern, with an occurrence rate of one in 100,000. It is caused by a deficiency of the enzyme glutaryl-CoA dehydrogenase (GCDH), encoded by the GCDH gene on chromosome 19. It is an important enzyme in the catabolism of amino acids such as tryptophan, lysine, and hydroxylysine. Its deficiency leads to the accumulation of organic acids such as glutaric acid and 3-hydroxyglutaric acid, which interfere with cerebral energy metabolism and cause neurological symptoms. Here, we discuss the case of a six-month-old male child who presented with status epilepticus following an eight-day history of fever. The child was started on anti-epileptics. Initially, the child was on non-invasive ventilation and was later intubated and taken on a mechanical ventilator. A magnetic resonance imaging (MRI) scan of the brain was performed, and the findings suggested GA1. The child was started on carnitine after samples were sent for tandem mass spectrometry (TMS) and urine gas chromatography-mass spectrometry (GC/MS), which came out to be positive for GA1. Despite the timely intervention, the child did not survive. Most cases exhibit movement disorders, with many presenting in acute encephalitic crises. Additionally, a significant portion of patients experience an insidious onset of the disease. An MRI of the brain shows widened Sylvian fissures in the majority of cases. Treatment of GA1 includes dietary modifications, including a low-lysine diet and administering carnitine. Early diagnosis and management result in decreased mortality and morbidity, which underscores the need for newborn screening.

A Rare Presentation of Glucose-6-Phosphate Dehydrogenase Deficiency.

Approximately 400 million individuals globally experience glucose-6-phosphate dehydrogenase (G6PD) insufficiency, an enzymatic condition that may be hazardous. Because of mutations in the G6PD gene, which result in functional variants alongside a variety of biochemical and clinical symptoms, this condition is an X-linked hereditary genetic disorder. Our case is that of a 12-year-old male child who presented with acute liver failure and later on, exhibited signs of hemolysis as well. We had to rule out the possibilities of acetaminophen toxicity and hepatitis A before reaching the conclusion that an underlying G6PD deficiency was being exacerbated by viral infection and simultaneous ingestion of non-steroidal anti-inflammatory drugs (NSAIDs).

Isolated Malignant Pleural Effusion in a Child: Unusual Presentation of Acute Leukemia.

Pleural effusion in the pediatric population is an abnormal pathology characterized by the accumulation of fluids between the parietal and visceral pleura. The etiology of this excessive fluid accumulation can be attributed to both infectious and non-infectious factors. Notably, Streptococcus pneumoniae stands out as the predominant infectious agent responsible for this condition. Non-infectious causative factors encompass hematolymphoid malignancies, congestive heart failure, hemothorax, hypoalbuminemia, and iatrogenic causes. Among the hematolymphoid malignancies, lymphoma emerges as the most prevalent malignancy associated with pleural effusion. It is followed by T-cell lymphoblastic leukemia, germ cell tumor, neurogenic tumor, chest wall and pulmonary malignancy, carcinoid tumor, pleuro-pulmonary blastoma, and Askin's tumor, among others. Malignant pleural effusion is predominantly linked to T-cell lymphoblastic malignancies. In the context of acute lymphoblastic leukemia (ALL), cases where T-cell presentation is accompanied by leukemic pleural effusion are commonly associated with either a mediastinal mass or significant lymphadenopathy. Here, we describe a case of a four-year-old male child who exhibited a brief history of febrile illness. Notably, this case was characterized by isolated pleural effusion, devoid of any mediastinal mass or lymphadenopathy. Pathological investigations of pleural fluid analysis revealed the presence of malignant cells, facilitating an expedited diagnosis.

A Case Report of Central Bronchiectasis in a Poorly Controlled Asthmatic Adolescent With Allergic Bronchopulmonary Aspergillosis and Secondary Spontaneous Pneumothorax.

Allergic bronchopulmonary aspergillosis (ABPA) is a multifaceted immune hypersensitivity reaction occurring in the lungs and bronchi, triggered by exposure and colonization of Aspergillus species, commonly Aspergillus fumigatus (A. fumigatus). It typically affects individuals who are immunocompetent but predisposed, such as those with bronchial asthma and cystic fibrosis. Diagnosis involves various methods including chest radiography, computed tomography, identification of eosinophilia, elevated serum IgE (immunoglobulin E) levels, and immunological tests for Aspergillus antigen. Left undiagnosed and untreated, ABPA can advance to bronchiectasis and/or pulmonary fibrosis, leading to significant morbidity and mortality.

Comparative Analysis of C-reactive Protein and Procalcitonin as Biomarkers for Prognostic Assessment in Pediatric Sepsis.

Background Sepsis poses a critical medical challenge due to its profound systemic inflammatory response, which frequently results in organ dysfunction and high mortality rates, especially in pediatric patients. The condition requires prompt recognition and aggressive management to mitigate its severe outcomes. Methods This prospective study enrolled 248 pediatric patients admitted with sepsis to the pediatric intensive care unit (PICU) at our tertiary care center. Patients were randomly assigned to either the C-reactive protein (CRP) or procalcitonin (PCT) groups, with biomarker levels measured upon admission (hour zero) and again at 72 hours post-admission. Clinical parameters such as the need for ionotropic support, use of steroids, incidence of acute kidney injury (AKI), requirement for invasive ventilation, patient outcomes, and changes in antibiotic management were assessed based on these biomarker levels. Results Procalcitonin-positive sepsis cases demonstrated notable clinical severity compared to their C-reactive protein counterparts, showing significantly lower systolic blood pressure (p = 0.012), heightened need for ionotropic support (p < 0.0001), and more pronounced liver and renal dysfunction as indicated by elevated serum bilirubin (p = 0.001) and creatinine levels (p = 0.0058). The incidence of AKI was also higher in procalcitonin-positive cases. Despite these severe clinical parameters, there were no significant differences in the length of the PICU stay or in patient outcomes concerning discharge and mortality rates. Procalcitonin levels effectively guided antibiotic management, resulting in therapy adjustments in a substantial proportion of cases, with 67 (54%) experiencing downgrades and 33 (27%) requiring upgrades based on procalcitonin levels measured 72 hours post-admission. Conclusion Procalcitonin proves to be a valuable biomarker in assessing the severity and management of sepsis in pediatric patients. It correlates significantly with clinical parameters such as blood pressure, the need for ionotropic support, and markers of organ dysfunction.

Pilomyxoid Astrocytoma Presenting With Developmental Regression: A Case Report.

Pilomyxoid astrocytoma (PMA) is a subtype of pilocytic astrocytoma (PA). PMA tends to exhibit a more aggressive course compared to PA. We present a case of a two-year-old male with a PMA in the suprasellar region who presented with developmental regression, loss of previously attained milestones such as the ability to hold his neck, walk, and talk, along with hypotonia in all four limbs. Serum cortisol and thyroid-stimulating hormone (TSH) levels were measured to rule out endocrine disturbances and were within normal limits. Magnetic resonance imaging (MRI) of the brain showed a solid lesion in the suprasellar region, extending into the pituitary and interpeduncular fossae, compressing the pituitary gland, and effacing the third ventricle, causing cerebrospinal fluid (CSF) flow obstruction and lateral ventricle dilation. The tumor appears hypointense on T1 and hyperintense on T2, with fluid-attenuated inversion recovery (FLAIR), peripheral contrast enhancement, and no calcification, consistent with PMA. The CSF analysis was negative for malignant cells. Histopathological examination revealed monomorphous bipolar and spindle cells in an angiocentric pattern with a myxoid background, without rosenthal fibers, mitoses, or eosinophilic granular bodies, consistent with PMA but not seen in PA. Immunohistochemistry showed strong positivity for glial fibrillary acidic protein (GFAP) and S100, with a Ki-67 index of 3-4%, indicating a low-grade tumor. The preferred treatment is surgical resection, but due to the tumor's deep location and potential long-term neurological effects, the parents opted against surgery. A ventriculoperitoneal shunt was placed to alleviate CSF flow, following which the child showed mild improvement in symptoms. Treatment of nonresectable astrocytomas was controversial, but gross total surgical resection offers better disease control. Chemotherapy is for patients with recurrence or where total resection of the tumor is not possible, and radiotherapy, though the long-term disease control is good, has a variable visual outcome.

Wiskott-Aldrich Syndrome: A Report of a Rare X-Linked Disorder.

Wiskott-Aldrich syndrome (WAS) is a rare X-linked recessive genetic disorder marked by eczema, thrombocytopenia, and immunodeficiency. The associated immune dysregulation increases the risk of autoimmune disorders and lymphoid malignancies. WAS results from mutations in the WAS protein gene on the short arm of the X chromosome. Here, we present the case of a seven-month-old male, born to non-consanguineous parents with no significant birth or family history. The child had height, weight, and head circumference below the third percentile for age and presented with recurrent mild upper respiratory infections, mild eczema, and thrombocytopenia. Despite symptomatic treatment and clinical improvement, platelet counts continued to decline. A provisional diagnosis of immune thrombocytopenia was made, and intravenous immunoglobulin was administered, which halted the downward trend but did not improve platelet counts. Autoimmune testing revealed strong positivity for antinuclear antibodies (ANA). Given the early-onset thrombocytopenia, anemia, and failure to thrive, autoimmune lymphoproliferative syndrome was suspected. However, T cell subset analysis was normal. A bone marrow biopsy suggested myelodysplastic syndrome or myeloproliferative neoplasm, but molecular studies were negative. Due to the early-onset autoimmunity and strongly positive ANA, genetic testing via whole exome sequencing confirmed the diagnosis of WAS.

Association of Liver Function Tests With the Severity and Outcome of Dengue Fever in Children.

Background Dengue is one of the most common vector-borne diseases in India, and it is transmitted by Aedes family mosquitoes. Hepatic injury is known to occur from dengue infection. Direct hepatotoxicity and deranged host immune responses to the virus are responsible for this hepatic dysfunction. Hence, the study was undertaken to understand the deranged hepatic enzymes using liver function tests (LFTs) and the severity and outcome of dengue fever in children. Methods This study is an observational-descriptive study conducted between June 2022 and May 2024. The study population includes children between the ages of one month and 16 years who have been diagnosed with dengue fever and admitted to pediatric wards and pediatric intensive care units (PICUs), with a sample size of 151. Informed consent from guardians and institutional ethical clearance were obtained. Results A total of 4.8% (N = 7) mortality was seen in this study with dengue patients. Hepatomegaly was seen in 34% (N = 49) of cases. There is a clear statistical significance that is seen among the non-survived and survived dengue patients with a 10-fold increase in serum glutamic-oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) levels, respectively, along with total bilirubin, activated partial thromboplastin time (APTT), and prothrombin time (PT). Conclusions The current study shows that deranged LFTs are associated with more severe disease with more PICU admissions and mortality of the disease. The evidence clearly indicates the inclusion of LFTs as a routine investigation to understand the severity of the disease and the prognosis of the outcome.
