Infantile Colic: A Survey of Physicians in Pakistan.

Purpose: Infantile colic diagnostic criteria were established by Rome IV. A universally accepted management remains to be established. We aimed to evaluate diagnostic criteria, management strategies, and perceived regional prevalence of infantile colic in Pakistan, as well as its effect on physicians and parents. Methods: A questionnaire was distributed amongst 1,256 physicians. Results: We received 800 replies. Wessel and Rome IV criteria were used by most physicians for diagnosis; however, the response "any infant who cries a lot" was selected by older physicians (48% of those over 60 years), physicians in rural areas (32%), physicians practicing in private clinics (27%), and general physicians (30%). Estimated prevalence of infantile colic ranges from 21-40%. Reassurance was the most widely recommended management strategy followed by herbal teas (51%), switching to a different formula (49%), probiotics (28%) and antibiotics (26%), discontinuation of breastfeeding (14%), elimination of dairy products from the breastfeeding mothers' diet (6%), and the administration of colic drops (1%). Most physicians considered the negative impact of colic on their personal lives and the parents as mild-to-moderate. Notably, 38% of percent of physicians routinely screened for maternal depression, and 45% of physicians were aware of the association between infantile colic and shaken baby syndrome. Conclusion: Most physicians in Pakistan diagnose and manage infantile colic according to the established guidelines. However, the guidelines pertaining to treatment planning are not followed. Educational efforts directed toward general physicians and doctors practicing in rural areas and clinics must be implemented to avoid unnecessary testing and treatment burden.

Acute Porphyria: An Unusual Case Of Quadriparesis, Hypertension, Recurrent Severe Cyclic Abdominal Pain, And Seizures.

Porphyria refers to a rare group of genetically inherited or acquired disorders that arise due to reduced metabolic activity of any of the enzymes in the haem biosynthetic pathway. Defect in any enzyme causes the presentation of symptoms of porphyria. The epidemiology of Acute Intermittent Porphyria (AIP) is complicated because of its rarity and delay in diagnosis. We present the case of a seven-year-old girl who presented with multisystem involvement; her symptoms were quadriparesis, hypertension, recurrent severe cyclic abdominal pain, and seizures. These symptoms together were not explained by the differentials taken into account. She presented before puberty with no family history of such conditions, while being born of consanguineous marriage. Her symptoms along with urinary porphobilinogen positivity test helped to reach the diagnosis of AIP in the absence of cutaneous manifestations. This case highlights the variable presentation of porphyria and emphasises the importance of appropriate and timely diagnosis and management in these patients.

Idiopathic Pulmonary Haemosiderosis: An Unusual Case Of Anaemia With Pulmonary Involvement.

Idiopathic pulmonary haemosiderosis is a rare disorder, with recurrent life-threatening alveolar haemorrhages and chronic lung parenchymal changes. It is associated with a triad of haemoptysis, iron deficiency anaemia, and diffuse pulmonary infiltrates. Although most cases are idiopathic, secondary haemosiderosis linked to known diseases has also been observed. Most of the cases remain undiagnosed because the disease is very low on the list of differentials. There is no specified age for the disease. The present study reports on an adolescent female patient who presented with microcytic anaemia and bilateral lung infiltrates to the National Institute of Child Health (NICH), Karachi, a tertiary care hospital. She was diagnosed with Idiopathic pulmonary haemosiderosis after ruling out other possibilities.

Case report of a child with spontaneous pneumomediastinum and subcutaneous emphysema.

Hamman's syndrome is a rare clinical entity that presents with spontaneous pneumomediastinum and subcutaneous emphysema. It is most commonly diagnosed in young men and pregnant women, and is rare in children. We report the case of a female toddler who presented to an emergency department with fever, cough and shortness of breath. Imaging studies revealed subcutaneous emphysema and pneumomediastinum. The patient was diagnosed with Hamman's syndrome after ruling out other possibilities. We discuss the underlying mechanisms of the disease, the diagnostic criteria and the treatment options. The purpose of this case report is to improve clinicians' awareness of the existence of this rare clinical entity in paediatric patients.

A relation between serum albumin level and prognosis of critically ill children admitted to the paediatric Intensive Care Unit.

OBJECTIVE: To determine the frequency of hypoalbuminaemia in critically ill children, and to assess the association of low serum albumin with clinical deterioration and outcome. METHODS: The prospective, descriptive study was conducted from September 1, 2020, to October 31, 2021, at the National Institute of Child Health, Karachi, and comprised critically ill children of either gender aged between 3 months and 16 years admitted to the paediatric intensive care unit. Serum albumin values were documented at 2 hours post-admission and at 24 hours. Paediatric Index of Mortality 2 score, Vasoactive Inotropic Score, and Paediatric Sequential Organ Failure Assessment scores were calculated. Hypoalbuminaemia was defined as serum albumin ≤3.3gdl. Data was analysed using SPSS 27. Results: Of the 110 patients, 70(63.6%) were boys and 40(36.4%) were girls. The overall mean age was 46.72±43.28 months. Hypoalbuminaemia at 24 hours was found in 74(67.3%) subjects compared to 60(54.5%) at 2 hours, and mean serum albumin was lower at 24 hours compared to 2 hours post-admission (p<0.05). Patients with hypoalbuminaemia had significant relation with Paediatric Index of Mortality 2 score, Vasoactive Inotropic Score, Paediatric Sequential Organ Failure Assessment score, and outcome (p<0.05). The risk of mortality was 4.1 times higher in patients with hypoalbuminaemia (p=0.001). CONCLUSIONS: The incidence of hypoalbuminaemia was found to be higher in children in intensive care settings, and hypoalbuminaemia was a significant independent predictor of mortality in a critically ill child.

Evaluation of the Resources and Inequities Among Pediatric Critical Care Facilities in Pakistan.

OBJECTIVES: To evaluate nationwide pediatric critical care facilities and resources in Pakistan. DESIGN: Cross-sectional observational study. SETTING: Accredited pediatric training facilities in Pakistan. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A survey was conducted using the Partners in Health 4S (space, staff, stuff, systems) framework, via email or telephone correspondence. We used a scoring system in which each item in our checklist was given a score of 1, if available. Total scores were added up for each component. Additionally, we stratified and analyzed the data between the public and private healthcare sectors. Out of 114 hospitals (accredited for pediatric training), 76 (67%) responded. Fifty-three (70%) of these hospitals had a PICU, with a total of 667 specialized beds and 217 mechanical ventilators. There were 38 (72%) public hospitals and 15 (28%) private hospitals. There were 20 trained intensivists in 16 of 53 PICUs (30%), while 25 of 53 PICUs (47%) had a nurse-patient ratio less than 1:3. Overall, private hospitals were better resourced in many domains of our four Partners in Health framework. The Stuff component scored more than the other three components using analysis of variance testing ( p = 0.003). On cluster analysis, private hospitals ranked higher in Space and Stuff, along with the overall scoring. CONCLUSIONS: There is a general lack of resources, seen disproportionately in the public sector. The scarcity of qualified intensivists and nursing staff poses a challenge to Pakistan's PICU infrastructure.

Clinical and epidemiological features of pediatric population hospitalized with COVID-19: a multicenter longitudinal study (March 2020-December 2021) from Pakistan.

Background: We aimed to explore the epidemiological, clinical, and phenotypic parameters of pediatric patients hospitalized with COVID-19 in Pakistan. Methods: This longitudinal cohort study was conducted in five tertiary care hospitals in Pakistan from March 2020 to December 2021. Data on various epidemiological and clinical variables were collected using Case Report Forms (CRFs) adapted from the WHO COVID-19 clinical data platform at baseline and at monthly follow-ups for 3 months. Findings: A total of 1090 children were included. The median age was 5 years (Interquartile range 1-10), and the majority presented due to new signs/symptoms associated with COVID-19 (57.8%; n = 631), the most common being general and respiratory symptoms. Comorbidities were present in 417 (38.3%) children. Acute COVID-19 alone was found in 932 (85.5%) children, 81 (7.4%) had multisystem inflammatory syndrome (MIS-C), 77 (7.0%) had overlapping features of acute COVID-19 and MIS-C, and severe disease was found in 775/1086 (71.4%). Steroids were given to 351 (32.2%) patients while 77 (7.1%) children received intravenous immunoglobulins. Intensive care unit (ICU) care was required in 334 (31.6%) patients, and 203 (18.3%) deaths were reported during the study period. The largest spike in cases and mortality was from July to September 2021 when the Delta variant first emerged. During the first and second follow-ups, 37 and 10 children expired respectively, and medical care after discharge was required in 204 (25.4%), 94 (16.6%), and 70 (13.7%) children respectively during each monthly follow-up. Interpretation: Our study highlights that acute COVID-19 was the major phenotype associated with high severity and mortality in children in Pakistan in contrast to what has been observed globally. Funding: The study was supported by the World Health Organization (WHO), which was involved in the study design but played no role in its analysis, writeup, or publication.

A quasi experimental study to compare thermo-regulator blanket with conventional method (incubator) for temperature regulations in preterm, low birth weight neonates landing at emergency department of a tertiary care paediatric facility.

Objective: To compare incubator and thermal blanket for thermoregulation in preterm and low birth weight neonates. METHODS: The pilot study was conducted from January to March 2018 at the emergency department of the National Institute of Child Health, Karachi, and comprised preterm and low birth weight neonates without any co-morbidity who were randomised to control and interventional groups. Data was collected using a proforma about demographics, weight, gestational age and brief clinical history. Temperature, blood pressure and pulse were monitored along with other routine care after every 15 minutes in the incubator, and the same procedure was adopted for thermal blankets. Data was analysed using Statistical Package for Social Sciences (SPSS) Version 23. RESULTS: Of the 38 subjects, 19(50%) each were cases and controls. The mean gestational age between the groups was not significantly different (p>0.05). Temperature for the first 60 minutes remained similar in the two groups, but at 75 minutes and onwards, the incubator showed a significantly better results (p<0.05). Conclusion: Thermal blankets can sufficiently provide a hyperthermic environment to the neonates, but an incubator is a more reliable option to provide sustained temperature.

Comparing Finger-stick Βeta-hydroxybutyrate with Dipstick Urine Tests in the Detection of Ketone Bodies in the Diagnosis of Children with Diabetic Ketoacidosis.

OBJECTIVE: To compare the finger-stick ß-hydroxybutyrate (ß-OHB) method accuracy with dipstick urine test for the detection of ketone bodies to diagnose diabetic ketoacidosis in children. STUDY DESIGN: Cross-sectional study. PLACE AND DURATION OF STUDY: Department of Pediatrics, National Institute of Child Health, Karachi, from March to August 2021. METHODOLOGY: Ninety-six known or newly diagnosed diabetic patients aged 2-15 years with suboptimal glycemic control and diabetic ketoacidosis were included in the study. A urine dipstick test was utilised to evaluate the absence or presence of ketones in the urine. In point-of-care, blood ß-OHB levels were recorded. RESULTS: Among 96 children, with median age of 10 years (IQR=6-11), 11 (11.5%) children had traces of urine ketones, 7 (7.3%) had + urine ketones, 19 (19.8%) had ++ urine ketones, 26 (27.1%) had +++ ketones and 19 (19.8%) had ++++ ketones. In 66 patients (68.75%), capillary blood ketone was observed to be positive by a finger-stick ß-OHB method. The finger-stick ß-OHB method had a higher sensitivity (90.4% vs. 84.9%), specificity (100% vs. 91.3%), and accuracy (92.7% vs. 86.5%) than the dipstick urine test. CONCLUSION: Finger-stick ß-OHB method can serve as a more accurate alternative to the urinary dipstick method for the measurement of ketones and to exclude ketosis and diagnosis of diabetic ketoacidosis (DKA) in hyperglycemic children. KEY WORDS: Diabetes mellitus, Hyperglycemia, Diabetic ketoacidosis, Point-of-care testing, Ketosis, Urine ketones, Acetoacetates.

Comparison of Pediatric Sequential Organ Failure Assessment and Pediatric Risk of Mortality III Score as Mortality Prediction in Pediatric Intensive Care Unit.

OBJECTIVE: To assess and compare the diagnostic accuracy of the Pediatric Risk of Mortality (PRISM) III score and Pediatric Sequential Organ Failure Assessment (p-SOFA) for the prediction of mortality in critically ill children. METHODOLOGY: This was a cross-validation study conducted at the Pediatric Intensive Care Unit (PICU) of the National Institute of Child Health Karachi from February 2021 to July 2021. Two hundred eighty-six critically ill children of age one month to 15 years of either gender staying in PICU for more than 24 hours were included. Within 24 hours of admission, the p-SOFA and PRISM III 24 scores were calculated for all eligible children. The outcome of the study was mortality within 30 days of PICU admitted children. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 23. RESULTS: The median age was 24 months (range: 1-144 months). The 30-day mortality was estimated as 57%. The p-SOFA and PRISM scores were significantly greater in children who did not survive than survivors. The maximum p-SOFA score (area under the curve (AUC)=0.81, 95% CI=0.76-0.86, p=0.001) and PRISM III 24 score (AUC=0.75, 95% CI=0.69-0.81, p=0.001) had good discrimination for 30-day mortality. For the prediction of 30-day mortality at the cut-off value of p-SOFA>2, the sensitivity was 93.87%, specificity was 38.21%, and accuracy was 69.93%. Whereas at the cut-off value of PRISM III 24 score>8, the sensitivity was 55.83%, specificity was 77.24%, and accuracy was 65.03%. CONCLUSION: The p-SOFA score is a good predictor for 30-day mortality in critically ill children and had better accuracy than the PRISM III 24 score.

Pediatric Risk of Mortality III Score in Predicting Mortality Among Diabetic Ketoacidosis Patients in a Pediatric Intensive Care Unit.

Background Diabetic ketoacidosis (DKA) is one of the most common complications of type 1 diabetes. Mortality is not uncommon in DKA, mostly in younger children with severe DKA and those complicated with cerebral edema. Early identification of high-risk patients can help in timely interventions to improve the outcome of DKA. Pediatric Risk of Mortality (PRISM III) is a standard scoring system to objectively predict the prognosis and outcome of pediatric intensive care unit (PICU) patients. Objective To predict the need for inotrope and mechanical ventilation and mortality rate using PRISM III in DKA patients admitted to PICU. Methods A prospective observational study was conducted in the PICU of the National Institute of Child Health, Karachi, from February 2020 to September 2021 involving 114 children. PRISM III scoring protocol was applied. A PRISM III score of >8 predicted higher mortality risk.  Results The mean PRISM III score was 6.56 ± 3.18 with 30 (26.3%) children having a score >8. Of the 30 (26.31%) patients with >8 PRISM III scores, 14 (46.67%) needed inotropic support, 6 (20%) needed mechanical ventilation, and there were eight (26.67%) mortalities. There was no reported mortality among patients with a PRISM III score ≤8. All differences were statistically significant (p < .05). Conclusion PRISM III is a highly sophisticated scoring system that can aid clinicians in the early prediction of adverse clinical outcomes in patients with DKA. Robust scientific evidence supporting its clinical application can help practically improve the outcome of DKA in young patients.

Frequency of Drug Induced Acute Kidney Injury in Pediatric Intensive Care Unit.

BACKGROUND: Acute kidney injury (AKI) is known to complicate one-third of cases in pediatric intensive care units (PICU), and almost one-fourth of these are due to nephrotoxic drugs (NTDs). Although stopping NTDs seems the most obvious option, it is not practically applicable. Many NTDs are the only existing option, and their potential benefits outweigh the risk of drug-induced AKI. OBJECTIVES: To assess the proportion of children receiving NTDs in the PICU and highlight the children who developed AKI. METHODS: A prospective observational study was conducted in the PICU of the National Institute of Child Health, Karachi. All children admitted to the PICU for at least 72 hours not diagnosed with any acute or chronic kidney disease were included. Serum creatinine (SCr) was done at admission and then after 72 hours. Data was entered and analyzed using IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp. RESULTS: Of 99 children, 53 (53.5%) were male. NTD exposure was positive in 97 (97.9%), and 72 (72.7%) had high exposure (≥3 NTDs). Drug-induced AKI was diagnosed in 46 (46.5%). It was significantly related to high SCr even at admission and high NTDs exposure. The mortality rate in the AKI group was 17% compared to 4% in the non-AKI (p=0.02). CONCLUSION: Almost half of all PICU admissions were infants. Almost all patients were exposed to NTDs, and three-fourth experienced high exposure. AKI developed in 46% of patients and may be predicted by raised creatinine at the time of admission. Children exposed to ≥3 NTDs had a higher chance of drug-induced AKI.

Correlation Between the Ratio of Oxygen Saturation to Fraction of Inspired Oxygen and the Ratio of Partial Pressure of Oxygen to Fraction of Inspired Oxygen in Detection and Risk Stratification of Pediatric Acute Respiratory Distress Syndrome.

OBJECTIVE: To measure the correlation between the ratio of oxygen saturation to fraction of inspired oxygen [SpO2/FiO2 (SF)] and the ratio of partial pressure of oxygen to fraction of inspired oxygen [PaO2/FiO2 (PF)] among children diagnosed with acute respiratory distress syndrome (ARDS). METHODOLOGY:  A cross-sectional study was conducted at the pediatric intensive care unit (PICU), National Institute of Child Health (NICH), Karachi, a tertiary care government hospital, from November 2020 to July 2021. One hundred twenty children (of either gender) having the age range of 2 months to 16 years, admitted to PICU with acute onset of respiratory distress, were included in the study. We measured SpO2, PaO2, FiO2 and calculated SF and PF ratios. SPSS (version 23) (Armonk, NY: IBM Corp) was used to analyze data, and the Spearmen's correlation test was applied to measure the relationship between SF and PF ratios. RESULTS: A total of 120 children were included, the mean age was 40.58±38.88 months and 67 (55.8%) were males. The mean FiO2 was 76.33%, the mean PaO2 and SpO2 were 100.35 mmHg and 94.37%, respectively. The mean PF ratio was 156.34, and the mean SF ratio was 156.45. There was a strong correlation between the SF ratio and the PF ratio (r=0.688; p=0.001). CONCLUSION: This study has shown that there is a strong correlation between the SF and PF ratios, and a statistically substantial agreement has been observed.

The Spectrum of Pediatric Cardiac Procedures and Their Outcomes: A Six-month Report from the Largest Cardiac Facility in Sindh, Pakistan.

Introduction Congenital heart disease (CHD) is the most common birth defect globally, with low-to-middle income Asian countries registering the highest incidence. Every year, 60,000 babies are born with varying severity of CHD in Pakistan. But the country has only three pediatric intensive care units (PICU) fully dedicated to child cardiac surgery patients. The focus of this study is to analyze the spectrum of pediatric cardiac surgical procedures performed for the management of CHD and their outcomes in a cardiac PICU in Pakistan. Methods In this analysis, all surgical records of children admitted to the PICU of National Institute of Cardiovascular Diseases (NICVD), Karachi, from October 2018 to March 2019 were included. It is a 14-bed, state-of-the-art cardiac PICU, which provides high-quality care to critical post-surgical patients. Results The surgical records of 537 patients were extracted for the purpose of our study, which accounted for 89.5 of post-operative patients admitted in the PICU per month and three per day. Tetralogy of Fallot (TOF) was the most commonly treated anomaly (n = 161; 29.9%) in the facility, followed by ventricular septal defect (n = 107; 19.9%). The overall mortality rate was 5.4% (n = 29), out of which 27.5% (n = 8) were TOF-related. Conclusions There is a very high burden of patients on the cardiac PICUs in low-to-middle income Asian countries. Despite the lack of resources, the high- quality care provided by pediatric cardiac critical-care specialists at these PICUs has ensured favorable outcomes and a mortality rate as low as that in any of the developed countries.

Disease Spectrum and Frequency of Illness in Pediatric Emergency: A Retrospective Analysis From Karachi, Pakistan.

Background: The National Institute of Child Health (NICH) is the largest tertiary care pediatric hospital operating in Karachi, Pakistan. Its emergency department (ED) is always occupied. However, the spectrum of illness in patients presenting to this ED has not been investigated in depth to identify the most common presentations and to develop effective management for treating patients. Methods: This retrospective study included all children visiting the pediatric ED of the NICH from January 2017 through December 2017. Newborns to children 14 years of age were included, for a total cohort of 188,803 patients. Sociodemographic data and clinical information were extracted from the medical record. Univariate analysis was performed to determine the frequency and percentage for all the variables. Results: The cohort consisted of 9% (n=16,952) neonates (0 to 1 month) and 91% (n=171,351) older children (>1 month to 14 years). Among the neonates, 36.6% presented as triage level 1. Sepsis was diagnosed in 23.8% of neonates, low birth weight/preterm in 18.4%, and respiratory distress/pneumonia in 15.2%. In infants and older children, diagnoses related to the respiratory system (37.3%), gastrointestinal system (16.4%), and multisystem involvement (15.9%) were the most common. During the evening shifts, 38.1% of patients were seen, and on weekends, 51.6% of patients were seen. Sunday was the busiest day in the ED. Conclusion: The tertiary care pediatric EDs in Pakistan have witnessed an increasing number of critical emergencies over time. Respiratory and gastrointestinal emergencies form the majority of the ED burden. A surge of patients is seen on the weekends and during the evening shifts. The spectrum of illnesses should be investigated via prospective, longitudinal studies in other pediatric EDs in Pakistan to understand the trends and to provide the foundation for developing nationwide recommendations for improving pediatric emergency care.

Response to nebulized salbutamol versus combination with ipratropium bromide in children with acute severe asthma.

OBJECTIVE: To compare the efficacy of nebulised salbutamol alone and in combination with ipratropium bromide in acute severe asthma in children. METHODS: The randomised controlled trial was conducted at the National Institute of Child Health, Karachi, from October 2012 to March 2013, and comprised patients with acute severe asthma who were randomised into two equal groups. Group A patients received 3 doses of nebulised salbutamol alone (0.03 ml/kg/dose) at 15-minute intervals and Group B received 3 similar doses of salbutamol along with ipratropium (250 ug/dose). Acute severe asthma was categorised as serve exacerbation (clinical score >10) and moderate (5-10 score) based on Bentur Modification. Efficacy was measured after 5minutes of the last dose by change in severity score from severe exacerbation (baseline) to low score. SPSS 10 was used for statistical analysis. RESULTS: There were two groups of 100(50%) patients each. The mean age in Group A was 9.1±3 years and 9.3±2.8 years in Group B. Male-Female ratio in Group A was 1.5:1 and in Group B it was 1.2:1. In Group B, 93(93%) children showed improvement in clinical score (<10 score) while it was 84(84%) in Group A. There was better response in clinical score in Group A than Group B, but it was not significant (p>0.05). CONCLUSIONS: The combination of nebulised salbutamol along with ipratropium bromide in the treatment of acute asthma exacerbation was not superior to salbutamol alone.

A cross sectional study on juvenile idiopathic arthritis in paediatric population.

OBJECTIVE: To determine the frequency of common subtypes of juvenile idiopathic arthritis among paediatric population. METHODS: The cross-sectional study was conducted at the National Institute of Child Health, Karachi, from January to June, 2010, and comprised children below 16 years of age with arthritis in one or more joints for at least 6 weeks. Physical examination was done and detailed history was recorded. When >5 joints of the body were involved, it was considered polyarthritis. If <4 joints were involved, it was pauciarticular arthritis. RESULTS: Of the 95 cases in the study, 52(54.7%) were girls and 43(45.3%) were boys, with an overall mean age of 11±1.2 years. Polyarticular arthritis was found in 51(53.7%) subjects and pauciarticular arthritis in 44(46.3%). Out of 43 boys, 27(62.8%) had pauciarticular, while 35(67.3%) of the 52 girls had polyarticular arthritis. CONCLUSIONS: Polyarticular arthritis was the most common sub-type. Proportion of polyarticular arthritis was high in female children, while pauciarticular arthritis was high in male children.
