The use of tranexamic acid in percutaneous nephrolithotomy is safe, and is associated with reduced blood loss and a lower complication rate.

Objectives To describe the epidemiological and clinical characteristics and outcome of hospitalized children with COVID-19 during the initial phase of the pandemic. Methods This was a cross-sectional descriptive study conducted at the dedicated COVID-19 hospital of a tertiary care referral center in North India. Consecutive children aged 14 y or younger who tested positive for SARS-CoV-2 by RT-PCR from nasopharyngeal swab between 1 April 2020 and 15 July 2020 were included. Results Of 31 children with median (IQR) age of 33 (9-96) mo, 9 (29%) were infants. About 74% (n = 23) had history of household contact. Comorbidities were noted in 6 (19%) children. More than half (58%) were asymptomatic. Of 13 symptomatic children, median (IQR) duration of symptoms was 2 (1-5.5) d. Fever (32%) was most common followed by cough (19%), rapid breathing (13%), diarrhea (10%) and vomiting (10%). Severe [n = 4, 13%] and critical [n = 1, 3%] illnesses were noted more commonly in infants with comorbidities. Three (10%) children required PICU admission and invasive ventilation; one died. Median (IQR) length of hospital stay was 15 (11-20) d. Follow up RT-PCR before discharge was performed in 17 children and the median (IQR) duration to RT-PCR negativity was 16 (12-19) d. Conclusions In the early pandemic, most children with COVID-19 had a household contact and presented with asymptomatic or mild illness. Severe and critical illness were observed in young infants and those with comorbidities.

In 2020, a considerable overlap occurred between the COVID-19 pandemic and seasonal dengue transmission in India. This study aimed to evaluate the effects of acute or recent infection with SARS-CoV-2 on the course and outcomes of dengue fever in children. We prospectively enrolled 44 children with a clinical and laboratory diagnosis of dengue fever. Assessment of acute and recent SARS-CoV-2 infection was done using reverse transcription–polymerase chain reaction and IgG antibody through ELISA. Children were grouped based on evidence of SARS-CoV-2 exposure and clinical severity, and outcomes were compared. The median age of the study cohort was 96 months (interquartile range [IQR]: 69–129 months). Fever (98%), vomiting (78%), abdominal pain (68%), hepatomegaly (68%), and edema (32%) were the common features. About two-thirds (N = 30) had severe dengue; 20 (45%) had dengue shock. Liver dysfunction (58%) and acute kidney injury (25%) were other major organ dysfunctions. Nineteen (43%) children stayed in the pediatric intensive care unit for a median duration of 5 days (IQR: 2–11 days). None had acute SARS-CoV2 infection; however, IgG against SARS-CoV-2 was detected in 15 (34%) cases. Children with recent exposure to SARS-CoV-2 showed a trend toward a lower incidence of acute kidney injury, fewer organ dysfunctions, and a lower frequency of invasive ventilation. Four children (9%) died; none of the deaths were in the SARS-CoV-2–exposed group. The present study exposes preliminary evidence that dengue fever might follow a less severe course in children with recent exposure to SARS-CoV-2 infection. However, it is pertinent to understand the antigenic similarity and cross-protective antibody response between the two viruses and their clinical relevance.

Background Staphylococcus aureus co-infection is seldom reported in children with severe dengue. Methodology In this retrospective study, we reported five children with severe dengue and S. aureus co-infection admitted to pediatric intensive care unit (PICU) during July–December 2021. Results All children had prolonged fever, persistence of bilateral pleural effusion beyond the critical phase, thrombocytopenia and raised inflammatory markers [C-reactive protein (CRP) and procalcitonin]. S. aureus was isolated from pleural fluid (n = 2, 40%), blood (n = 2, 40%) and endotracheal aspirate (n = 1, 20%). Four children (80%) grew methicillin-sensitive S. aureus, while 1 (20%) had methicillin-resistant S. aureus. Two children (40%) had septic thromboemboli in skin, and 1 (20%) had limb cellulitis. One child required anterior thoracotomy, pericardiectomy and bilateral pleural decortication, while all other children required intercostal chest tube drainage. All children required prolonged targeted antibiotics, invasive mechanical ventilation and had prolong stay in PICU and all of them survived. Conclusion In children with severe dengue, persistence of fever, persistence of pleural effusion beyond critical phase and raised CRP and procalcitonin should raise suspicion of bacterial/S. aureus co-infection.

Acute encephalitis is a syndromic diagnosis. In the last two decades, a unique clinico-radiological entity, named acute encephalopathy with biphasic seizures and late restricted diffusion (AESD), has been reported in children from Asia. It is characterised by an acute febrile illness with seizures and encephalopathy, with some initial improvement followed by a second flurry of seizures and deep encephalopathy, 3–4 days later. MRI may show a pattern of ‘bright tree appearance’. An aetiological agent may not always be identified but an infectious trigger is proposed. Immunomodulatory therapy has been tried with variable results. The prognosis is variable, and children are usually left with neurological sequelae including epilepsy and cognitive impairment. We describe a female infant who presented with the typical clinico-radiological syndrome of AESD and human bocavirus was identified in the stool. She received steroids and antiepileptic drugs. She has persistent cognitive impairment at follow-up but remained seizure free.
