Multiple Lower Limb Fractures in a Child With Spinal Muscular Atrophy Type 2: A Preventable Complication.

Patients with spinal muscular atrophy (SMA) are at risk of poor bone health and fractures. We report a child with SMA type 2, presenting with acute pain and swelling of both lower limbs following physiotherapy, and found to have multiple fractures in both lower limbs. Literature on fractures in children with SMA is limited. Awareness of risk assessment and appropriate preventive measures among healthcare providers caring for children with SMA is essential.

Scrub typhus presenting with massive splenomegaly in an adolescent boy.

Scrub typhus is a serious public health problem in the Asia Pacific region. Early diagnosis and treatment can prevent complications and mortality. Splenomegaly in isolated scrub typhus is mostly mild or subclinical and rarely massive. We report an adolescent boy with scrub typhus presenting with fever, massive splenomegaly and severe anemia. Clinicians should be aware of atypical presentations of scrub typhus, which is easily treatable with minimal investigations.

An Observational Study on Pattern of Empirical Acyclovir Therapy in Children With Acute Encephalitis From Northern India.

OBJECTIVES: To identify the prevalence of herpes simplex encephalitis (HSE), factors influencing the duration of empirical acyclovir and frequency of acute kidney injury (AKI) in children with acute encephalitis syndrome (AES). DESIGN: Prospective observational study. SETTING: Pediatric Emergency Department and PICU of a tertiary hospital in Northern India. PATIENTS: All consecutive, eligible children between 1 month and 12 years old presenting with AES, defined as altered consciousness for greater than 24 hours (including lethargy, irritability, or a change in personality) and two or more of the following signs: 1) fever (temperature ≥ 38°C) during the current illness, 2) seizures or focal neurological signs, 3) cerebrospinal fluid (CSF) pleocytosis, 4) electroencephalogram, and/or 5) neuroimaging suggesting encephalitis, who received at least one dose of acyclovir. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 101 children screened, 83 were enrolled. The median (interquartile range [IQR]) age was 3 years (1-6 yr). Thirty-one children (37.3%) were diagnosed with AES, of which four were labeled as probable HSE (three based on MRI brain, one based on serology). Scrub typhus, dengue, Japanese encephalitis, and mumps were the other infective causes. The median (IQR) duration of acyclovir therapy was 72 hours (24-264 hr); 21 children (25.3%) received acyclovir for less than 24 hours and 11 (13.3%) for greater than or equal to 14 days. New-onset AKI was seen in 18 children (21.7%) but was mostly transient. Death ( n = 8, 9.6%) and discontinuation of care due to futility or other reasons ( n = 15, 18%) were noted in 23 children (28%). Factors associated with duration of acyclovir greater than 7 days, on univariable analysis, were lower modified Glasgow Coma Score at admission, requirement of invasive ventilation, invasive intracranial pressure monitoring, and CSF pleocytosis (5-500 cells). On multivariable analysis, only CSF pleocytosis of 5-500 cells was associated with duration of acyclovir greater than 7 days. CONCLUSIONS: Given the low prevalence of HSE, and the risk of AKI, this study sensitizes the need to review our practice on initiation and stopping of empirical acyclovir in children with acute encephalitis.

Case Report: Fulminant Infantile Beriberi: A Report of Six Cases.

Thiamine deficiency disorders are an under-recognized public health problem in low- and middle-income countries. Infantile beriberi, the most important symptom for children, is suspected to significantly contribute to infant mortality and lifelong neurodevelopmental morbidity. Lack of awareness, varied clinical presentation, and lack of a readily available diagnostic marker lead to frequent misdiagnoses. We report six thriving infants who presented with an acute fulminant illness with varied clinical manifestations mimicking common childhood illnesses like pneumonia and sepsis. Four of them presented with the severe cardiovascular form, called Shoshin beriberi, and severe pulmonary arterial hypertension. Empirical intravenous thiamine administered to four of the six infants resulted in dramatic recovery. Awareness of the clinical definition of infantile beriberi and treatment with empirical thiamine can be lifesaving.

Thrombocytopenia in severe iron deficiency anaemia: A report of two cases.

Iron deficiency, the commonest cause of anaemia in children, is a global public health problem. Worldwide, almost 50% of children <5 years of age are anaemic. Platelet count in iron deficiency anaemia is mostly normal or high; thrombocytopenia is rare. We describe two children with iron deficiency anaemia and severe thrombocytopenia who recovered with iron supplementation alone.

Pre-extubation ultrasonographic measurement of intracricoid peritubal free space: A pilot study to predict post-extubation airway obstruction in children.

OBJECTIVE: Post-extubation airway obstruction (PEAO) is common and difficult to predict in children. We hypothesized that Intracricoid Peritubal Free Space (IPFS) obtained by deducting the outer diameter of the endotracheal tube in situ (ODTT - provided by the manufacturer) from the ultrasonographically measured internal transverse cricoid diameter (ICDt) is likely to be inversely proportional to the risk of developing PEAO. This prospective observational study was planned to evaluate this hypothesis. METHODS: This study was conducted in a Pediatric Intensive Care Unit of a tertiary care teaching hospital in a low-middle income economy. Laryngotracheal ultrasound was performed just prior to the first elective extubation in 93 patients (3mo-12yrs) intubated for ≥ 48 h, to calculate the IPFS. Patients with pre-existent upper airway conditions, chronic respiratory diseases and poor airway reflexes were excluded. Patients with Westley's Croup Score (WCS) ≥4 were classified as PEAO, and those with WCS ≥7, as extubation failure (EF). RESULTS: Thirty-two (34%) patients developed PEAO, while seventeen (18%) developed EF. Baseline clinical characteristics were similar in patients with and without PEAO. IPFS was lesser in patients who developed PEAO (4.16 ± 1.18 mm vs. 5.28 ± 1.51 mm, p < 0.001) and EF (4.13 ± 1.44 mm vs. 5.07 ± 1.46 mm, p = 0.019) compared to those who did not. IPFS <5.16 mm predicted PEAO [sensitivity, 84%; positive predictive value (PPV), 87%; AUC, 0.714), while IPFS <3.77 mm predicted EF (specificity, 80%; PPV, 88%; AUC, 0.679). Combining clinical risk factors (presence of clinical edema, prolonged ventilation and younger age) and lesser IPFS helped develop a clinico-sonographic prediction model with improved predictability for PEAO and EF (AUC, 0.820 for both). CONCLUSIONS: Lesser IPFS is reasonably sensitive and specific to predict PEAO and EF respectively with high PPV. Combining clinical risk factors and IPFS improved the PPV further. Further studies with larger samples stratified for different age groups in different clinical settings are required to confirm these observations.

Clinical Profile of Critical Pertussis in Children at a Pediatric Intensive Care Unit in Northern India.

OBJECTIVE: To delineate the clinical profile, complications, intensive care needs, and predictors of mortality in children with critical pertussis. METHODS: Retrospective analysis of case records of children in the pediatric intensive care unit of a tertiary-care hospital, with a diagnosis of critical pertussis over 3 years. Diagnostic criteria included CDC case definition and confirmation by polymerase chain reaction (PCR), when available. Survivors and non-survivors were compared to identify predictors of mortality. RESULTS: 36 records were analysed, most cases were infants (31, 86.1%). 10 (27.7%) were (below 6 weeks of age). In the rest, 16 (61.5%) were partially immunized or unimmunized against pertussis. Rapid breathing (88.9%), paroxysmal cough (86.1%) and apnea (41.7%) were common presenting complaints. Hypoxemia (97.2%), hyperleukocytosis (61.1%) and encephalopathy (52.8%) were common complications. Intensive care needs were mechanical ventilation in 11 (30.6%), vasoactive support in 7 (19.4%) and exchange transfusion in 3 (8.3%). Female gender, apnea, hyperleukocytosis, encephalopathy, need for vasoactive support, and mechanical ventilation predicted mortality. CONCLUSIONS: Pertussis demands attention due to its varied presentation, increased complications and higher mortality.
