Item Accidental Inorganic Mercury Chloride Poisoning in a 2-Year Old Child.(2010-10) Verma, Sanjay; Kumar, Ramesh; Khadwal, Alka; Singhi, SunitInorganic mercury poisoning is uncommon, but when it occurs it can result in severe, life threatening features and acute renal failure. A 2-year old well thriving child presented with alleged history of accidental ingestion of inorganic mercury chloride. He presented with evidence of corrosive trauma to the gastrointestinal tract mucosa, but with normal renal function at admission, which was managed with BAL and other supportive treatment. But he developed non-oliguric renal failure after admission, which also improved gradually. On follow-up, two months later, the patient’s renal function was normal; indicating that renal failure caused by acute inorganic mercury poisoning produced no permanent renal damage. We have hereby presented a case of mercury intoxication in a 2-year old child, with an excellent clinical improvement and normalization of laboratory results.Item Are primary health workers skilled enough to assess the severity of illness among young infants?(2003-08-03) Bandyopadhyay, Sutapa; Kumar, Rajesh; Singhi, Sunit; Aggarwal, Arun KOBJECTIVE: To evaluate the skills of health workers in assessing the severity of illness among young infants. DESIGN: Cross sectional. SETTING: Five different health institutions viz, subcenter, primary health center, community health center, sub-divisional hospital, district hospital. METHODS: 110 young infants aged <2 months who attended the selected health institutions on specific week days were assessed by a physician. Subsequently 10 female health workers assessed these babies. Physician and health workers used same symptom and sign based guidelines for classification of the illness. Level of agreement between the physician and the health workers were assessed using kappa statistics. RESULTS: Physician classified 37.3% infants as not sick or mildly sick, 42.7% as moderately sick and 20% as severely sick. In comparison to the physician, the sensitivity and specificity of the health workers' assessment of severe illness was 77% and 76% respectively. Of 22 babies classified as severely sick by the physician, female health workers classified 5 as not sick or mildly sick, 8 as moderately sick and 9 as severely sick. On the other hand health workers classified one not sick or mildly sick and 9 moderately sick infants as severely sick. Level of agreement between the physician and health workers was poor (Kappa value = 0.39, 95% CI = 0.26, 0.52). Health workers misclassified illness mainly due to 'not counting the respiratory rate and 'not looking for chest retractions, purulent discharge and jaundice'. CONCLUSION: Trained health workers' skills were not satisfactory for assessment of illness severity among young infants. During training, importance of these signs needs to be emphasized.Item Hyponatraemia and hypovolemic shock with tuberculous meningitis.(2003-12-15) Dass, Rashna; Nagaraj, Ravishankar; Murlidharan, Jayashree; Singhi, SunitA 12-year-old boy with tuberculous meningitis and hydrocephalous, after undergoing revision of ventriculo-peritoneal shunt had persistent impairment of sensorium and episodes of hyponatremia (serum sodium 104 to 125 mmol/l), accompanied by polyuria, signs of poor peripheral, perfusion hypotension and low CVP, and high urinary sodium excretion (114-60 mmol/l). A diagnosis of cerebral salt wasting syndrome (CSWS) was made and was treated with saline replacement and fludrocortisone (10 microg/kg/day). Within next 3 days the sensorium, signs of shock, urine output and serum and urinary sodium returned to normal. The case illustrates that life-threatening hyponatremia in a child with neurological illness could be caused by CSWS, which must be differentiated from Syndrome of inappropriate antidiuretic hormone secretion (SIADH), as CSWS requires rigorous salt and volume replacement in contrast to fluid restriction in SIADH.Item Hyponatremia in hospitalized critically ill children: current concepts.(2004-09-28) Singhi, SunitHyponatremia (serum sodium to < 136 mEq/l) is the most common electrolyte abnormality in critically ill children. It could result from a deficit of sodium, or surplus of water. Impaired water excretion, 'inappropriate' release of vasopressin, use of hypotonic fluids, redistribution of sodium and water, sick cell syndrome, several drugs and primary illness all may contribute to hyponatremia. Acute hyponatremia, defined as a fall in serum sodium to ~ 120 mEq/l within 48 hours may result in acute cerebral edema and brain stem herniation particularly in children. However, there is paucity of data on hyponatremia in hospitalized critically ill patients. Studies addressing incidence, cause and outcome of hyponatremia in critically ill patients are needed to plan rational fluid therapy protocols, and resolve the current debate, which calls for abandonment of N/5 saline in 5% dextrose solution as maintenance intravenous fluid in favour of normal saline to prevent hyponatremia. At present it is not fully correct to assume that isotonic maintenance fluids would be superior to current maintenance fluids. Reducing the volume of maintenance fluid to about 75% of normal maintenance volume may be more appropriate way to prevent hyponatremia in view of water retaining effect of high ADH and reduced renal free water clearance in critically ill children.Item Infectious mononucleosis presenting as upper airway obstruction.(2003-04-29) Jain, Vivek; Singhi, Sunit; Desai, Ravi VUpper airway obstruction though a common complication of infectious mononucleosis is rarely considered in differential diagnosis of stridor. We report a three-year-old child who had upper airway obstruction due to infectious mononucleosis, managed conservatively with oxygen, intravenous fluids and steroids.Item Invasive candidiasis in pediatric intensive care units.(2009-10) Singhi, Sunit; Deep, AkashCandidemia and disseminated candidiasis are major causes of morbidity and mortality in hospitalized patients especially in the intensive care units (ICU). The incidence of invasive candidasis is on a steady rise because of increasing use of multiple antibiotics and invasive procedures carried out in the ICUs. Worldwide there is a shifting trend from C. albicans towards non albicans species, with an associated increase in mortality and antifungal resistance. In the ICU a predisposed host in one who is on broad spectrum antibiotics, parenteral nutrition, and central venous catheters. There are no pathognomonic signs or symptoms. The clinical clues are: unexplained fever or signs of severe sepsis or septic shock while on antibiotics, multiple, non-tender, nodular erythematous cutaneous lesions. The spectrum of infection with candida species range from superficial candidiasis of the skin and mucosa to more serious life threatening infections. Treatment of candidiasis involves removal of the most likely source of infection and drug therapy to speed up the clearance of infection. Amphotericin B remains the initial drug of first choice in hemodynamically unstable critically ill children in the wake of increasing resistance to azoles. Evaluation of newer antifungal agents and precise role of prophylactic therapy in ICU patients is needed.Item Low plasma zinc and iron in pica.(2003-02-29) Singhi, Sunit; Ravishanker, R; Singhi, Pratibha; Nath, ROBJECTIVE: To determine role of trace elements in causation of pica with specific reference to zinc and iron we studied plasma levels of iron (Fe), Zinc (Zn), calcium (Ca) and magnesium (Mg) and blood lead (Pb) levels by atomic absorption spectrophotometer in 31 children with pica (Pica Group) and 60 controls matched for age, sex and nutrition (Control Group) in an observational case and control study in the settings of outpatient clinic of a tertiary care, teaching hospital. METHODS: Data from each group were further stratified by hemoglobin level <9 and >9 g/dl into two subgroups pica-1 and pica-2, and control-1 and control-2 respectively, to control for confounding effect of iron deficiency anemia. RESULTS: The plasma Fe level (mean +/- SD) in children with pica (42.7 +/- 9.2) mg/dl) was about 20% lower than that in controls (51.5 +/- 10.0 mg/dl, p < 0.001). Plasma Zn levels in the pica group (60 +/- 4.4 mg/dl) was about 45% lower than those in controls (110.2 +/- 8.5 mg/dl, p<0.001). Correlation of Zn and Fe levels with pica-related variables such as age at onset, duration and frequency and number of inedible objects ingested was not significant. CONCLUSION: These findings suggest that hypozincemia with low iron levels may be the possible cause of pica and contradict the contention that low levels of plasma Zn and Fe could be an effect of pica.Item Neurocysticercosis in children.(2009-05) Singhi, Pratibha; Singhi, SunitNeurocysticercosis (NCC) is a common cause of seizures and neurologic disease. Although there may be variable presentations depending on the stage and location of cysts in the nervous system, most children (> 80%) present with seizures particularly partial seizures. About a third of cases have headache and vomiting. Diagnosis is made by either CT or MRI. Single enhancing lesions are the commonest visualization of a scolex confirms the diagnosis. Some cases have multiple cysts with a characterstic starry-sky appearance. Management involves use of anticonvulsants for seizures and steroids for cerebral edema. The use of cysticidal therapy continues to be debated. Controlled studies have shown that cysticidal therapy helps in increased and faster resolution of CT lesions. Improvement in long - term seizure control has not yet been proven. Children with single lesions have a good outcome and seizure recurrence rate is low. Children with multiple lesions have recurrent seizures. Extraparenchymal NCC has a guarded prognosis but it is rare in children. In endemic areas NCC must be considered in the differential diagnosis of seizures and various other neurological disorders.Item Nosocomial bloodstream infection in a pediatric intensive care unit.(2008-01-05) Singhi, Sunit; Ray, Pallab; Mathew, Joseph L; Jayashree, M; ,OBJECTIVE: To study the incidence of nosocomial blood stream infections (BSI) in a pediatric intensive care unit (PICU) of a tertiary care teaching hospital, identify the organisms responsible and the pattern of antibiotic resistance over one decade. METHODS: Data was retrieved from the records of PICU and Medical Microbiology laboratory of patients with a positive blood culture after 48 hours of admission to PICU over three time periods viz. 1994-1996, 1999-2001 and 2002-2003. Antibiotic sensitivity pattern was also analyzed. RESULTS: 861 episodes (1994-1996: 282, 1999-2001: 362 and 2002-2003: 217) of nosocomial bloodstream infection were documented in 841 patients, corresponding to 3.63, 5.94 and 4.99 episodes per 100 patient-days, respectively. Gram negative organisms were the predominant isolates; common being Klebsiella pneumoniae (20.1%), Enterobacter species (16.6%) and Acinetobacter species (8.6%). Staphylococcus aureus (16.4%) and yeast species (15.9%) were the major Gram positive isolates. Isolation of Staphylococcus aureus , Klebsiella and Acinetobacter species showed a rising trend while yeast (36.9%, 6.6% and 4.1%) showed a decline over the three time periods studied. An increasing trend of resistance to third generation cephalosporins, aminoglycosides, ciprofloxacin and newer antibiotics including combination of beta-lactam with beta-lactamase inhibitor was noted. CONCLUSION: The predominant organisms responsible for nosocomial infection in the PICU were Klebsiella pneumoniae , Staphylococcus aureus and Enterobacter species . At present, carbapenems plus vancomycin appear to be the best choice for empiric antibiotic therapy in the PICU in Chandigarh.Item Pediatric intensive care in India: why, how and role of global collaboration!(2008-06-02) Singhi, Sunit; Kissoon, N NiranjanItem PG thesis: idealistic vs realistic.(2007-09-29) Singhi, SunitItem Pneumococcal disease in India: The dilemma continues.(2014-08) Mathew, Joseph L; Singhi, SunitItem Predictors of long term neurological outcome in bacterial meningitis.(2007-04-04) Singhi, Pratibha; Bansal, Arun; Geeta, P; Singhi, SunitOBJECTIVE: To study the long-term neurological and developmental outcome and the clinical and laboratory predictors of sequelae in children with acute bacterial meningitis (ABM). METHODS: Detailed clinical and demographic data was retrieved from the medical records of study children. Subsequently they were followed up for a minimum of 12 months after discharge for development, neurological and hearing assessment. All sequelae were identified and divided into minor or major. For analysis data was divided into 2 groups those with sequelae and without sequelae at follow-up. Statistical analysis was done using SPSS version 10.00 and Epi Info version 2000. RESULTS: 61 boys and 19 girls, a mean age of 31.4 +/= 41.9 months at the time of ABM, were included in the study. Of these 62.5% children were infants. Mean age at follow-up was 58.6 +/= 47.2 months. Sequelae were observed in 32 (40%) children (8 (10%) minor and 24 (30%) major). Mean social quotient at follow-up was 92.8 +/= 32.6. Developmentally 22 (37.9%) children were normal and 20 (34.5%) had global delay. Seizures (P=0.015), cranial nerve palsy (P=0.0065), abnormal deep tendon reflexes (P=0.002), Glasgow coma scale score (GCS) < 8 (P = 0.044) at admission, a CSF culture positive for bacteria and abnormal findings on ultrasonography or computed tomography of head at admission had significant association with sequelae at follow-up. All children (7/7) who had infarct on CT scan (P=0.001) and 12 (80%) of 15 patients who had hydrocephalus (OR - 9.0, 95% CI - 2.03-45.6, P=0.001) diagnosed on CT scan developed severe sequelae. On multiple regressions GCS score <8, presence of cranial nerve palsy and abnormal deep tendon reflexes were independent predictors of sequelae. CONCLUSION: Neurological and audiological sequelae and global developmental delay may be seen in about one third of survivors of bacterial meningitis. GCS score <8, presence of infarct or cranial nerve palsy, or hydrocephalous on CT/ ultrasound at admission may help in identification of children most likely to need long term follow up and rehabilitation.Item Randomized evaluation of fluid resuscitation with crystalloid (saline) and colloid (polymer from degraded gelatin in saline) in pediatric septic shock.(2005-03-09) Upadhyay, Manasaranjan; Singhi, Sunit; Murlidharan, Jayashree; Kaur, Navkiran; Majumdar, SOBJECTIVE: To compare the efficacy of crystalloid (Normal saline) and colloid (polymer from degraded Gelatin in saline Haemaccel) intravenous fluid in restoration of circulating volume in children with septic shock. DESIGN: Prospective, randomized, open-label trial. SETTING: Pediatric Emergency and Intensive Care Unit of a tertiary care referral and teaching hospital. SUBJECTS AND INCLUSION CRITERIA: Sixty patients, between 1 month to 12 years of age, with septic shock, without clinical evidence of organ failure at admission or underlying immunodeficiency. INTERVENTION: Resuscitation with normal saline or polymer from degraded gelatin (Haemaccel) in the boluses rate of 20 mL/kg till hemodynamic stabilization or if central venous pressure (CVP) exceeded 10 mmHg (fluid requirement beyond 40 mL/kg guided by BP and CVP). METHODS: Hemodynamic parameters (heart rate, capillary filling time, pulse volume, and blood pressure) were recorded before and during resuscitation, and then 2 hourly for 12 hours. Central venous pressure line was placed within first hour, soon after starting fluids. Estimation of plasma volume and body water was done at the end of first hour of fluid resuscitation. OUTCOME MEASURES: Hemodynamic stabilization (heart rate, capillary refill time, systolic BP in normal range), plasma volume at the end of fluid resuscitation and incidence of organ dysfunction. RESULTS: 31 patients were randomized to normal saline and 29 to gelatin polymer. Both the groups were similar with respect to age, gender, primary diagnosis, initial hemodynamic parameters and PRISM score. Pneumonia (n = 22; 36%), gut-associated sepsis (n = 13), and dengue hemorrhagic fever (n = 11) were the common primary diagnosis. Initial hemodynamic stabilization was achieved in all. The mean (SD plasma volume (saline--53.4 (2.0 mL/kg, gelatin polymer--53.2 (1.9 mL/kg), extracellular fluid volume, total body water and interstitial fluid volume at the end of first hour of resuscitation were similar. The requirement of inotropes, incidence of organ dysfunction and case fatality rate (Saline--29%, gelatin polymer--31%), were similar in two groups. CONCLUSION: Both normal saline and gelatin polymer solution were equally effective as resuscitation fluid with respect to restoration of plasma volume and hemodynamic stability. Normal saline upto 110 mL/kg, and gelatin polymer solution upto 70 mL/kg may be required in first hour for successful fluid resuscitation of septic shock in children.Item Reply.(2010-03) Jayashree, M; Singhi, SunitItem Scrub Typhus Associated with Guillain–Barré Syndrome (GBS)(Dr. K C Chaudhuri Foundation, 2022-11) Raghunathan, Veena; Dhaliwal, Maninder; Singhi, Pratibha; Singhi, SunitScrub typhus is a vector-borne disease caused by Orientia tsutsugamushi. Clinical manifestations generally occur due to vasculitis and infammation and can have variable degrees of systemic involvement. Meningoencephalitis and cerebellitis are well-known neurological manifestations of scrub typhus, but the occurrence of Guillain–Barré syndrome is extremely rare. The authors report a 7-y-old boy who developed fever followed by rapidly progressive ascending quadriparesis with arefexia and whose etiological workup revealed positive IgM scrub typhus antibody, as well as, a high OXK titer (1:80). Nerve-conduction studies in all four limbs were suggestive of demyelinating neuropathy. He showed complete recovery after treatment with intravenous immunoglobulin (2 g/kg) and azithromycin.Item Status epilepticus: emergency management.(2003-03-06) Singhi, Sunit; Singhi, Pratibha; Dass, RashnaStatus Epilepticus (SE) is a medical emergency and requires prompt and aggressive treatment. Stabilization of airway, breathing and circulation and expeditious termination of seizures are immediate goals. Intravenous benzodiazepines-diazepam, midazolam or lorazepam and phenytoin are the first line drugs recommended for termination of seizures. Diazepam (or midazolam), thiopental and propofol infusion are useful for control of Refractory SE (RSE). Newer drugs are being investigated for use in SE. We prefer diazepam infusion. In children the mortality from SE ranges from 3-10% and the morbidity is twice. Mortality and morbidity are highest with SE associated with CNS infections, which is the most important cause of SE in our country. The outcome depends on the underlying etiology, age, rapidity of SE and adequacy of care. Adherence to a time-framed protocol in the emergency department helps in improving the final outcome.Item Toxic shock syndrome.(2004-05-28) Dass, Rashna; Nishad, P; Singhi, SunitThe authors present two children who had fever >or=38.9 degree C, diffuse rash, hypotension, deranged renal and hepatic functions, disseminated intravascular coagulation, altered sensorium and inflamed oral mucosa. They responded to fluids, inotropes, antibiotics and intravenous immunoglobulin (2 g/kg). Desquamation particularly of palms and soles and periungal region was noted 1 to 2 weeks after onset of illness. These features were consistent with the diagnosis of staphylococcal toxic shock syndrome (TSS). The cases highlight that TSS is very much with us and can mimic a variety of other diseases. Early recognition, and aggressive antimicrobial supportive and IVIG therapy cover can ensure complete recovery.
