Cerebrospinal fluid Gene XPERT (CBNAAT) in children with tuberculous meningitis.

OBJECTIVES: To observe the role of CSF Gene XPERT (CBNAAT) in diagnosis of tuberculous meningitis (TBM) and determine its sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). METHODS: A prospective study was done from October 2017 to March 2020. CSF samples of 55 children diagnosed as tuberculous meningitis as per defined clinical and imaging criteria, were subjected to routine CSF analysis, MGIT culture and CBNAAT. Children on prior anti-tuberculous therapy for more than one month were excluded from study. RESULTS: Of 55 children, meningeal signs were present in 54.5% children. Neurological deficits were present in 47.3%. Common CT brain findings were communicating hydrocephalus followed by infarct and basal exudates. CSF Gene XPERT (CBNAAT) were positive in 9 (16.4%), of which 6 was also culture positive and 3; negative. Two children were rifampicin resistant. Fifteen (27.3%) children had positive CSF culture. Gene XPERT showed sensitivity, specificity, PPV, NPV and diagnostic accuracy of 40%, 92.5%, 66.7%, 80.4% and 78.2% respectively as compared to culture. CONCLUSION: Although sensitivity of CSF CBNAAT is low i.e. 40% but positive result not only confirm bacteriological diagnosis of tuberculous meningitis but also reveal about rifampicin sensitivity and resistance for plan of therapy.

Echocardiography versus cardiac biomarkers for myocardial dysfunction in children with scorpion envenomation: An observational study from tertiary care center in northern India.

OBJECTIVE: This study was done to evaluate myocardial function by 2D Echocardiography and Cardiac biomarkers (cTnI, CK-MB, BNP) changes in patients of scorpion envenomation of grade II-IV and correlate mortality of envenomed children with myocardial dysfunction. METHODS: A total of 40 patients admitted consecutively with grade II and more scorpion envenomation from October 2015 to July2018 were enrolled in the study. The data included demographics, the time of presentation, clinical features, echocardiographic findings, electrocardiographic findings, cardiac biomarker levels at admission and discharge, use of inotropic medication, oral prazosin, time of discharge, and their outcome. RESULTS: The most common ECG abnormality was sinus tachycardia 28 (70%) followed by low voltage complex 13 (32.5%) which got normalized at the time of discharge in majority. Cardiac troponin I (cTnI) levels were more than 0.1 ng/mL, suggesting myocarditis was present in 25 (62.5%) and got normalized at discharge. CK-MB levels were increased in 26 (65%) patients suggesting myocardial involvement. BNP levels were also increased in 24 (60%) patients suggesting heart failure and its value got normalized at discharge. Abnormal 2D Echo findings as reduced left ventricular ejection fraction (LVEF) was present in 18 (45%) cases suggesting myocardial dysfunction and became normal at discharge. The sensitivity, specificity, positive predictive value and negative predictive value of Cardiac troponin I (cTnI) considering ECHO cardiograph as gold standard were 100, 68.1, 72 and 100% respectively. One patient had died whose Ejection fraction was less than 30%. CONCLUSION: Echocardiography and cTnI can identify subgroup of patients, who require early aggressive therapy. Echocardiography, if not available, cardiac troponin I level can guide early therapy and indicates the prognosis.

Evaluating the Impact of Breastfeeding on Rotavirus Antigenemia and Disease Severity in Indian Children.

OBJECTIVES: To evaluate the contribution of breastfeeding to Rotavirus (RV)-induced antigenemia and/or RNAemia and disease severity in Indian children (<2 yrs age). METHODS: Paired stool and serum samples were collected from (a) hospitalized infants with diarrhea (n = 145) and (b) healthy control infants without diarrhea (n = 28). Stool RV-antigen was screened in both groups by commercial rapid-test and enzyme immunoassay. The disease severity was scored and real-time-PCR was used for viral-load estimation. Serum was evaluated for RV-antigenemia by EIA and RV-RNAemia by RT-PCR. Data was stratified by age-group and breastfeeding status and compared. RESULTS: Presence of RV-antigenemia and RV-RNAemia was positively related with presence of RV in stool. Disease severity and stool viral-load was significantly associated with RV-antigenemia [(r = 0.74; CI:0.66 to 0.84; P<0.0001,R2 = 0.59) and (r = -0.55; CI:-0.68 to -0.39; P<0.0001,R2 = 0.31) respectively], but not with RV-RNAemia. There was significant reduction in RV-antigenemiarate in the breast-fed group compared to non-breastfed infants, especially in 0-6 month age group (P<0.001). Non-breastfed infants were at risk for RV-antigenemia with severe disease manifestations in form of high Vesikari scores correlating with high fever, more vomiting episodes and dehydration. CONCLUSION: RV-antigenemia was common in nonbreastfed children with severe RV-diarrhea and correlated with stool RV-load and disease severity.

Cognitive and behaviour dysfunction of children with neurocysticercosis: a cross-sectional study.

Eighty-three confirmed cases of neurocysticercosis diagnosed as per modified delBrutto criteria were enrolled in the study (Group-I) to observe cognitive and behavioural changes. Controls consisted of two groups: children with idiopathic generalized tonic-clonic seizure (Group-II) and normal children with non-specific cough (Group-III). Cases and controls were subjected to cognitive and behaviour assessment. There was significant difference in the intelligence quotient (IQ) of cases in domains of visual perception, immediate recall, analysis synthesis and reasoning, verbal ability, memory and spatial ability. In the age group of 6-18 years, cases had significantly more behaviour problems than control without seizure, in domains of anxious depressed, withdrawn depressed, somatic problems, social problems and rule-breaking behaviour. Neurocysticercosis causes decline in cognitive function and behaviours in older children, which should be recognized early for appropriate management and to avoid undue parental anxiety.

Association of possible osteopetrosis with acute myeloid leukaemia in a child.

Osteopetrosis is a rare disease characterised by an increase in bone mass, skeletal malformations and bone marrow failure due to defective bone resorption. We report a 3-month-old male child presented with chest infections, failure to thrive and hepatosplenomegaly and diagnosed with osteopetrosis associated with acute myeloid leukaemia M3 type (AML-M3). The patient died on day 7 of admission due to respiratory failure. To our knowledge, this is the first case where both osteopetrosis and AML is diagnosed in a patient.

Unilateral pulmonary artery agenesis with vertebral anomaly.

We report a two-and-half-year-old boy who presented with recurrent respiratory tract infections. He had cortriatum of right atrium, spina bifida occulta, hemivertebra and dysplastic right thumb. On CT of chest, he had also unilateral pulmonary artery agenesis. The case is being reported because of common manifestations of rare disease and its associated cardiac and skeletal abnormalities.

Disseminated cysticercosis with a right common femoral vein thrombosis.

Disseminated cysticercosis is an uncommon presentation of cysticercosis. Less than 10 cases of disseminated cysticercosis have been reported worldwide in children. We report the case of an 8-year-old boy with disseminated cysticercosis, who had presented with a swelling of the body for 1 month and proptosis of the eyeballs for 14 days. On examination, he had bilateral proptosis, subcutaneous nodules and hypertrophy of muscles of the limbs, neck and face. The CT cranium was normal, but the orbit showed bilateral bulky extraocular muscles heterogeneous in their whole length. The MRI cranium and whole body showed multiple non-enhancing vesicular cysts involving the brain, extraocular muscle, heart, trunk and muscles of the extremities and subcutaneous tissues. A Doppler study of the femoral vein showed thrombosis of the right common femoral vein. He was managed with corticosteroid, albendazole, phenytoin sodium, low-molecular-weight heparin followed by warfarin for 6 months and recovered completely.

Status epilepticus in a child with Sanjad Sakati syndrome.

We report a 6-year-old boy who presented with status epilepticus, who had facial dysmorphism, growth and mental retardation. On investigation, he had hypocalcaemia, hypoparathyroidism and bilateral calcification of basal ganglia in cranial tomographs; features consistent with Sanjad Sakati syndrome. He was treated with intravenous calcium gluconate initially followed by oral calcium and calcitriol and recovered completely.

Chronic abdominal pain in children.

Chronic abdominal pain in children is usually not caused by organic disease. Diagnostic triage focuses on the assessment of alarm symptoms by means of history and physical examination. Additional diagnostic evaluation is not required in children without alarm symptoms. Family characteristics have an important influence on the chronicity of abdominal pain. A specific intervention is not recommended owing to lack of evidence of a beneficial effect. The greatest challenge is to identify children at risk of a prolonged course of pain and its correlated functional disability. The evaluation of family for coping strategies, psychosocial factors and appropriate follow-up can prevent ineffective use of healthcare resources.

Immunosuppressive therapy in children.

The treatment of auto-immune diseases is evolving and newer agents become available. This review will outline treatment options in children with auto-immune disorders. Treatment with current corticosteroids and azathioprine works in majority but issues of intolerance and incomplete response arise, which led to window of newer immunosuppressants including mycophenolate mofetil, cyclosporine, tacrolimus, sirolimus, and various antibodies of human and animal origin. The newer agents have been studied in fewer numbers of children, so they are not first-line treatment yet but do have a clear role in patients with intolerance or incomplete response to standard therapy.

Portal hypertension with visceral leishmaniasis.

We conducted this study to observe evidence of portal hypertension in children with visceral leishmaniasis (VL). Eighty-eight consecutive cases (50 male) of VL were subjected to ultrasonography. Those with evidence of portal hypertension also underwent upper gastrointestinal endoscopy and liver biopsy. Eight patients had portal hypertension as evidenced by dilated caliber of portal and splenic veins. Two patients had periportal, splenic and peripancreatic collaterals and one patient had cavernous transformation of portal vein. Out of eight patients, four patients had esophageal and gastric varices. Liver biopsy was done in four patients and revealed hepatic sinusoidal dilations without any evidence of fibrosis. Portal hypertension may be an independent manifestation of VL and remain undiagnosed unless a physician maintains a high index of suspicion.

Amphotericin B therapy in children with visceral leishmaniasis: daily vs. alternate day, a randomized trial.

A randomized study was carried out to compare the efficacy and adverse reactions of daily vs. alternate day regimens of amphotericin B in children with visceral leishmaniasis (VL). Six hundred and five children of VL below 14 years of age were randomized into two groups; Group A (302), who received amphotericin B at a dose of 1 mg kg(-1) day(-1) for 15 days and Group B (303); same doses but on alternate days. All patients in both groups were cured, who had completed course of amphotericin B therapy. None had relapsed at 1 and 6 months of follow-up. Adverse reactions in both groups were non-significant. The duration of stay and cost of therapy was significantly lower in Group A children who left the hospital against medical advice, which was also significantly more in Group B. Thus, daily regimen of amphotericin B is equally effective, well tolerated, not more toxic and cost-effective than alternate day regimen, which is currently practiced.

Tubercular abscess of pons in a child with quadriparesis.

Tuberculous brain abscess is a rare manifestation of tuberculosis of the central nervous system. We report a case of a 6-year-old girl with a pontine tuberculous abscess, who presented with fever and quadriparesis and recovered completely after stereotactic aspiration and antituberculous treatment with four drugs (isoniazid, rifampicin, pyrazinamide, and ethambutol). Tuberculous abscess was confirmed based on findings of magnetic resonance imaging, a positive tuberculin test, and the presence of acid fast bacilli in smear and culture of abscess aspirate.

Cysticercal encephalitis with cortical blindness.

The authors report a 6-year-old boy, who had presented with low-grade fever, altered sensorium, headache and seizure for 5 days. On examination, he had features of raised intracranial pressure with left VI cranial-nerve palsy and bilateral extensor plantar response. CT scan showed multiple calcifications in cerebral cortex. MRI cranium showed multiple cysts involving whole of the brain. He was diagnosed as having cysticercal encephalitis, based on immunological and imaging study. He was managed with 20% mannitol, phenytoin and albendazole, and regained consciousness 7 days later, but had residual neurological deficit as left-lower-limb monoparesis and visual acuity of just projection of rays (PR+) and perception of light (PL+).

Osteogenesis imperfecta with partial trisomy 15.

Osteogenesis imperfecta (OI) is the most common genetic cause of osteoporosis, which presents as multiple fractures of bone. Mutations in the loci COL1A1 on band 17q21 and COL1A2 on band 7q22 have been reported as the cause in most cases of OI, but partial trisomy 15 has not been reported previously as a possible cause. A 3-month-old child with OI with an unusual association of partial trisomy 15 is reported.

Arteriovenous malformation of brain with stroke in Down syndrome: a case report.

Down syndrome is a common chromosomal aberration in children. A variety of associated malformations have been reported in the literature, including vascular malformations of pelvic organs. The vascular malformations of brain with Down syndrome have not been reported in the literature. Therefore, we report a child with Down syndrome, with associated arteriovenous malformation in the brain, who developed stroke and was treated successfully.

The co-existence of CHARGE and myelodysplastic syndrome in a child.

We report the case of an 8-month-old female child with co-existence of CHARGE with myelodysplastic syndrome, which is not reported in the literature. The patient was treated with packed cell transfusion, laser photocoagulation for retinal detachment, and antimicrobials, and referred for bone marrow transplantation.

Miltefosine in children with visceral leishmaniasis: a prospective, multicentric, cross-sectional study.

OBJECTIVE: Miltefosine, an alkyl phospholipid has been found effective against visceral leishmaniasis (VL) in adults in various studies. The authors safety, tolerance and efficacy of Miltefosine and compared with available gold standard anti-Ieishmanial drug, Amphotericin B, a parenteral formulation in children with VL. METHODS: All consecutive children aged 1 yr to 14 yr, presented with fever, splenomegaly and positive LD body in splenic smear examination, admitted in pediatric ward of Nalanda Medical college and Child care center between 1st July 03 to 30th June 05 were taken for study. Patients were randomized into four groups. Group-l and 2 patients were given Miltefosine in dose of 2.5 mg/Kg day o.d. or b.i.d. per orally to a maxiIpum of 100 mg and group 3 and 4 Amphotericin B at a dose of 1 mg/Kg/day (total: 15 mg/Kg). All patients were followed at completion of therapy, 3 months and 6 months for clinical response, splenic size and parasitologically. RESULTS: Out of 125 children, 44 were in group-I, 20 in group-2, 38 in group-3 and 23 in group- 4, 124 patients had parasitological cure with relapse in one patient of group 1 during follow up. One patient in-group II had no response with first course but became parasitologically negative with 2nd course of Miltefosine. In-group I, one patient had persistent splenomegaly and found to have associated portal hypertension. Final cure rate with Miltefosine and Amphotericin B was 93.2%, 95%, 92.1% and 91.3% in-group 1, 2, 3 and 4 respectively, which are statistically insignificant. Majority of patients had pancytopenia. Eievated". AL T (>3 times of normal) were seen in 28, 11, 19 and 13 patients of group 1, 2, 3 and group 4 respectively which returned to normal in subsequent follow up. Raised BUN was observed more in patients who got Amphotericin B i.e. 65.42% and 73.91 % in-group 3 and 4 respectively. GI side effects i.e. diarrhea and vomiting were observed in 26 and 23 patients in-group 1 and 2 respectively. CONCLUSION: Miltefosine is safe, well tolerable, and highly effective and has same efficacy as Amphotericin B in newly diagnosed and SAG resistant children with visceral leishmaniasis.
