Sentinel ear bleed as a presenting sign for carotid artery blowout due to aspergillus abscess in parapharyngeal space in an immunocompetent infant.

Parapharyngeal abscesses leading to complications, although rare after the advent of antibiotics, can lead to serious complications. One such complication is carotid erosion that can lead to a potentially fatal carotid artery blowout. We report a case of a previously healthy infant who presented with fever, ear bleed and progressively increasing swelling in the right side of his neck that led to airway compromise. The child required immediate securing of the airway at presentation. Imaging revealed lobulated abscess with multiple bleeding points eroding the carotid vessels, along with internal jugular venous thrombus. Surgical exploration was done and abscess debulked. Histopathology revealed aspergillus, which was treated with antifungals. He was discharged on oral warfarin after 40 days of hospital stay and remains well on follow-up. Sentinel ear bleed warrants close observation for possibility of carotid artery blowout in children with parapharyngeal abscesses.

Comparison of Specialist and Nonspecialist Transport Teams for Emergency Neurosurgery.

OBJECTIVES: Current guidance in the United Kingdom recommends that children requiring emergency neurosurgical intervention should be transported by referring hospital (RH) teams. We aimed to compare transports performed by RH teams and by specialized pediatric critical care transport (PCCTs) teams in terms of timings and patient outcomes. METHODS: We conducted a retrospective analysis over a 5-year period of children admitted from an external hospital to the pediatric intensive care unit at a pediatric neurosurgical center and receiving emergency neurosurgery within 24 hours of admission. Data were collected on RH characteristics, patient demographics, clinical status, transfer method (RH or PCCT team), timings (arrival at neurosurgical center, neurosurgical procedure), and clinical outcomes (length of stay and mortality). Univariate analysis was used to compare patient characteristics, times, and outcomes between RH and PCCT team transfers. Survival analysis was performed to analyze arrival time by transfer modality. RESULTS: During the study period, 75 children with acute neurosurgical emergencies were transferred. Median age was 6.7 years (interquartile range, 1.8-10.7), and 63% had nontraumatic diagnoses. The commonest mode of transfer was by RH teams after initial referral to a PCCT team (53.3%). The median distance was greatest for transfers by RH teams (14 km). Overall median arrival time was 5 hours (interquartile range, 3.6-7.4) with no significant difference between groups ( P = 0.3). Median length of pediatric intensive care unit stay and mortality did not differ between groups. CONCLUSIONS: Specialist critical care transport teams are involved in one third of transfers of children with acute neurosurgical emergencies. While the overriding priority is timely transfer, a tailored approach to the use of PCCTs may be appropriate particularly for children presenting to hospitals nearer to neurosurgical centers.

0.45% Versus 0.9% Saline in 5% Dextrose as Maintenance Fluids in Children Admitted With Acute Illness: A Randomized Control Trial.

BACKGROUND: The safety of giving intravenous (IV) maintenance fluids according to Holliday and Segar's recommendations of 1957 has recently been questioned after reports of complications caused by iatrogenic hyponatremia in children receiving hypotonic fluids. However, the current practice of choice of maintenance IV fluids for hospitalized children varies worldwide. This study was planned to compare 0.45% and 0.9% saline in 5% dextrose at standard maintenance rates in hospitalized children aged 3 months to 12 years. OBJECTIVE: Primary objective was to study change in serum sodium level at 24 hours in children receiving total IV fluid maintenance therapy as 0.45% or 0.9% normal saline in 5% dextrose. Secondary objectives of this study were to estimate change in serum sodium levels from the baseline to 48 or 72 hours, if IV fluids were continued, and to find incidence of hyponatremia and hypernatremia after administering these 2 types of maintenance fluids. METHODS: This study was an open-label, randomized control trial conducted at the Department of Pediatrics of a tertiary care hospital from July 22, 2019, to October 28, 2019. Two hundred children aged 3 months to 12 years admitted in pediatric emergency and requiring IV maintenance fluid were randomized into 2 groups (group A received 0.45% saline in 5% dextrose, group B received 0.9% normal saline in 5% dextrose) with 100 in each group. RESULTS: Both groups were comparable for baseline characteristics. Fall in mean serum sodium from baseline was more with increasing duration of IV fluids until 24 hours in 0.45% saline group as compared with 0.9% saline group, which was statistically significant (P < 0.001). The incidence of mild and moderate hyponatremia was significantly more in hypotonic group at 12 hours (P < 0.001) and 24 hours (P < 0.001). However, there was no significant difference at 48 hours. CONCLUSIONS: The fall in serum sodium values was significant, and there was significant risk of hyponatremia with the use of hypotonic fluids at 12 and 24 hours. Hence, the use of isotonic fluids seems to be more appropriate among the hospitalized children.Trial Registration: CTRI/2019/10/021791.

Effect of Concomitant Tuberculosis Infection on COVID-19 Disease in Children: A Matched, Retrospective Cohort Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has had devastating effects on the health of millions globally. Patients with tuberculosis (TB) are a vulnerable population. There is paucity of data to assess association between the 2 diseases in Pediatric population. OBJECTIVE: To elucidate the effect of concomitant TB on clinical course of pediatric COVID-19 disease. METHODS: Retrospective matched cohort study was conducted at dedicated tertiary COVID-19 hospital in India. All consecutive patients aged <18 y admitted with COVID-19 were line listed. Patients with current or recently diagnosed TB were included. Consecutive age and sex matched COVID-19 patients with no history of TB were included as controls. Medical records were retrieved, clinical data entered in pre-determined proforma. RESULTS: During study period, 327 pediatric COVID-19 patients were admitted. Study group included 17 patients with TB. These patients, tended to be referred from other hospitals, be sicker, had lower SpO2 at arrival and higher severity of COVID-19 as compared to controls (All P < 0.05). They required more mechanical ventilation, had longer length of stay and worse outcome. CONCLUSION: COVID-19 may secondarily affect and modify the course of TB in children. Given the high case fatality rate in this association and potentially treatable nature of TB, attention of the policy makers is drawn to this.

Paroxysmal Sympathetic Hyperactivity in Neurocritical Children: A Pilot Study.

Background: Paroxysmal sympathetic hyperactivity (PSH) is characterized by the abnormal excessive sympathetic response to acute cerebral insult. There is a paucity of data about this condition in children. This study was planned to analyze the incidence of PSH among children requiring neurocritical care and its association with the outcome. Materials and methods: The study was conducted in the pediatric intensive care unit (PICU) of a tertiary care hospital over a period of 10 months. Children of age 1 month to 12 years admitted with neurocritical illnesses were included. Children who were declared brain dead after initial resuscitation were excluded from the study. The criterion laid by Moeller et al. was used for the diagnosis for PSH. Results: During the study period, 54 children requiring neurocritical care were included in the study. The incidence of PSH was 5/54 (9.2%). Additionally, 30 (55.5%) children had less than four criteria for PSH and were termed as "incomplete PSH." Children with all four criteria for PSH had a significantly longer duration of mechanical ventilation, PICU stay, and higher PRISM III scores. Children with less than four criteria for PSH also had a longer duration of mechanical ventilation and stay. However, there was no significant difference in mortality. Conclusion: Paroxysmal sympathetic hyperactivity is common in children with neurological illnesses admitted to the PICU and is associated with longer mechanical ventilation and stay in PICU. They also had higher illness severity scores. Timely diagnosis of the condition and appropriate management is required to improve the outcome of these children.

Purulent pericardial effusion in children: Experience from a tertiary care center in North India.

BACKGROUND: Purulent pericarditis, if not recognized and managed timely, it can lead to significant morbidity and mortality. There are no guidelines for the management of purulent pericardial effusion in pediatric patients. AIM: The study describes our experience with the management of 22 patients admitted with a primary diagnosis of purulent pericardial effusion seen over a 7-year period. MATERIALS AND METHODS: Hospital records of 22 children admitted to the pediatric intensive care unit with purulent pericardial effusion during January 2012-December 2018 were retrospectively analyzed. RESULTS: The mean age of presentation was 4.6 years. The most common presentation was fever. History of antecedent trauma was present in 27.27% of patients. Empyema was the most common associated infection. Staphylococcus aureus was the most commonly isolated organism. Out of 22, pericardial drainage was done in 13 patients (59%). Only one of these patients required pericardiectomy later on. Six (27.2%) patients responded to antibiotics alone. Three (13.6%) patients died before any intervention could be planned. CONCLUSION: Echocardiography-guided percutaneous pericardiocentesis and pigtail catheter placement are a safe and effective treatment for purulent pericardial effusion. When pericardial drainage is not amenable, close monitoring of the size of effusion by serial echocardiography is required. Small residual pericardial effusion may be managed conservatively.

Use of terlipressin in critically ill children with liver disease.

BACKGROUND: Terlipressin, a long-acting synthetic analogue of vasopressin has been used in the adult population for various indications including hepatorenal syndrome (HRS-AKI), esophageal variceal hemorrhage (EVH) and shock, but its use in pediatrics is still limited to individualized cases and data on safety and efficacy is scant. METHODS: We reviewed the patient records of children with liver disease and Acute Kidney Injury requiring terlipressin admitted to the Paediatric Intensive Care Unit (PICU) of King's College Hospital, London from January 2010-December 2017, with special emphasis on its effect on renal parameters and adverse event profile. RESULTS: Twenty-one terlipressin administration records in a total of 16 patients (median) (IQR) 10 years (6.1-14.4) were included. The drug was initially given as a bolus dose in all cases, followed by either bolus or infusion with median dosage being 5.2 (3.8-6.7) mcg/kg/hour. After administration, a sustained increase of mean arterial pressure was observed. There was an improvement in serum creatinine (Cr) (at 24 h; p = 0.386) and increase in urine output (UO), especially in the hepatorenal syndrome subgroup (HRS-AKI). We found minimal evidence of gastrointestinal side effects including feeding intolerance and vasoconstrictive side effects including cyanosis / ischaemia of extremities. CONCLUSION: Terlipressin was found to be safe in critically sick children with liver disease with positive impact on renal parameters which might be taken as a surrogate marker of HRS reversal, though effects on outcomes are difficult to ascertain. It is important to be aware of all its side-effects and actively watch for them. Future prospective studies are warranted to validate these findings.

Acute kidney injury in children with chronic liver disease.

Acute kidney injury (AKI) is a common accompaniment in patients with liver disease. The causes, risk factors, manifestations and management of AKI in these patients vary according to the liver disease in question (acute liver failure, acute-on-chronic liver failure, post-liver transplantation or metabolic liver disease). There are multiple causes of AKI in patients with liver disease-pre-renal, acute tubular necrosis, post-renal, drug-induced renal failure and hepatorenal syndrome (HRS). Definitions of AKI in liver failure are periodically revised and updated, but pediatric definitions have still to see the light of the day. As our understanding of the pathophysiology of liver disease and renal involvement improves, treatment modalities have become more advanced and rationalized. Treatment includes reversing precipitating factors, such as infections and gastrointestinal bleeding, volume expansion, paracentesis and vasoconstrictors. This approach is tried and tested in adults. A pediatric tailored approach is still lacking due to inadequate numbers of patients, differences in causes of AKI and paucity of literature. In this review, we attempt to explore the pathophysiological basis, treatment modalities and controversies in the diagnosis and treatment of AKI in pediatric patients with chronic liver disease and discuss our own personal practice. We recognize that, although it is not a very commonly encountered entity in pediatric population, HRS has specific diagnostic criteria and treatment modalities that differ from other causes of AKI in patients with chronic liver disease; hence among the etiologies of kidney injury in patients with chronic liver disease, we focus here on HRS.

Outcome of anti-retroviral treatment in HIV-infected orphans and non-orphans at an ART centre in North India.

BACKGROUND: Few Indian studies have reported the long-term efficacy of anti-retroviral treatment (ART) in children and in orphaned, HIV-infected children in particular. AIM: To study differences in outcome of ART in HIV-infected orphans compared with non-orphans. METHODS: A retrospective study of 87 HIV-infected children who commenced ART in the period January 2006 to August 2007. The main measures were orphan status, absolute CD4 count and weight-for-height (WHZ) and height-for-age (HAZ) Z-scores. RESULTS: Median follow-up was 33 months. Forty (45·9%) children were orphaned. Orphans and non-orphans had similar baseline median WHZ and HAZ (-2·48 vs -2·63, P = 0·65 and -2·78 vs -2·91, P = 0·77, respectively). The two groups were similar in terms of WHO clinical stage and frequency of severe immunosuppression at presentation (P = 0·88 and 0·25, respectively). After ART initiation, the median absolute CD4 count increased progressively in both groups. Median WHZ and HAZ increased throughout the study period in the orphans and reached -1 at 27 and 39 months of ART, respectively. In the non-orphans, WHZ remained below that of the orphan group, the difference becoming statistically significant from 18 months of ART. The increment in HAZ in the non-orphan group was at par with the orphan group until 12 months of follow-up, after which it fell between 18 and 30 months. Subsequently, HAZ rose but remained below that of the orphan group. Both WHZ and HAZ failed to reach -1 in the non-orphan group. In both groups, 85% reported 100% adherence to ART. CONCLUSION: The outcome of ART is not affected by orphan status with the extended family adequately supporting orphaned children. Growth of children whose parents are HIV-infected may be constrained despite ART if there is inadequate family support.

Demographic and clinical features of orphans and nonorphans at a pediatric HIV centre in North India.

OBJECTIVE: To determine the prevalence of orphanhood among HIV positive children and to compare their social and demographic and clinical characteristics with that of HIV-positive non-orphans. METHODS: From February 2008 through March 2009, data was collected from 148 children registered at the antiretroviral (ART) clinic of a tertiary care hospital in Delhi, on their demographic profile, HIV status of parents, orphan status and cause of parental death, mode of transmission of the infection, current caregiver, school enrollment and clinical and immunologic parameters of HIV infection at presentation. RESULTS: The prevalence of orphanhood was 49.3%. Majority of the orphans were paternal orphans. The primary caregiver was either the surviving parent or extended family members. The orphans were older at presentation and had shorter mean duration of follow-up. They lagged behind the non-orphans in immunisation, nutritional status, school enrollment and attendance and socioeconomic status. They presented more frequently with severe immunosuppression and had a higher prevalence of opportunistic infections. There was no significant difference between the orphans and the non-orphans in the WHO clinical stage of presentation and adherence to ART. CONCLUSIONS: The prevalence of orphanhood among the HIV-positive children is high. Although extended family is a cornerstone for care of HIV-positive orphans, these families are overwhelmed by the added responsibility of these children. Larger community-based studies are needed to determine the true magnitude of orphanhood and to evolve methods to socially and financially support the families taking care of these children.
