Challenges in handling a civilian mass pediatric disaster during flood relief in a partially inundated armed forces medical facility

BACKGROUND

Armed forces hospitals are often called upon to provide medical aid to civilians during natural calamities. Though children are often the most vulnerable segment of population in these events, research that addresses their unique needs and the role of armed forces hospitals remains sparse.

OBJECTIVES

We examined pediatric morbidity and mortality at a flooded armed forces hospital. Factors that affected outcomes were identified.

METHODS

158 patients were evacuated en masse from a children's hospital in northern India that was submerged by flood to an adjacent partially inundated armed forces hospital specializing in military medicine and adult trauma. The children were provided case-based clinical care as per existing disaster management protocol. Geoclimatic vulnerability factors, morbidity/mortality, and medical and logistical challenges for future intervention were investigated.

RESULTS

One pediatrician who provided initial triage was joined by two others after 48 hours. A limited load of adult patients permitted more resources for the children, majority (49 percent) of whom were neonates. Intensive care was necessitated for 32 (20.2 percent) cases, with half managed in adult ICU. Overall in-hospital mortality was 5.7 percent. Experienced staff, cross-specialty multitasking, and innovative and noncensorious leadership were identified as assets amidst resources compromised by flooding. Clear delineation of primary caregiver role of pediatrician at outset, pediatric emergency care training, pediatric triage, resource allocation for thermoregulation, oxygen therapy and ventilation, earmarking centers for transfer of cases, and safe transportation to the centers were identified as areas meriting further attention.

CONCLUSION

Armed forces hospitals in vulnerable geoclimatic zones must address pediatric concerns in disaster management plans.

The diagnostic utility of rheumatoid factor and anticitrullinated protein antibody for rheumatoid arthritis in the Indian population

Background

There is lack of Indian data on diagnostic utility of rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) for diagnosis of rheumatoid arthritis (RA) and prevalence of these antibodies in patients with RA and the healthy population. The study was aimed to assess the diagnostic utility and prevalence of RF and ACPA at different titers in the Indian scenario.

Method

All the patients of RA fulfilling the European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) 2010 classification criteria and age and gender-matched healthy controls were included in the study. RF and ACPA were measured by nephelometry and the enzyme-linked immunosorbent assay (ELISA) method, respectively.

Result

Of 803 patients (291 men and 512 women) included, the RF was positive in 566 (70.5%) study patients. The ACPA was positive in 527 (71.7%) patients of 735 of them. Among 408 healthy controls, 45 (11%) were RF positive and 19 (4.7%) were ACPA positive.At the positive cutoff level, the RF had a specificity of 87.6% (95% confidence interval [CI] = 84.4-90.8; positive likelihood ratio [LR+] 5.7). Specificity at 2 and 3 times above the upper limit of normal (ULN) increased to 96.2% (95% CI = 94.3-98.1; LR+ 15.7) and 97.1% (95% CI = 95.5-98.7; LR+ 17.1), respectively.The specificity of ACPA at the positive cutoff level was 94.4% (95% CI = 92.2-96.6; LR+ 12.7), which increased to 98% (95% CI = 96.6-99.4), at 2xULN level. The likelihood ratio for ACPA at all cutoff levels measured was more than 10.

Conclusion

The sensitivity and specificity of RF and ACPA in our study population are comparable with those of other studies. ACPA at lower titers may have sufficient diagnostic utility for RA in an appropriate clinical setting.

Lessons Learnt From a Greenfield Hangar-Based 1,000-Bedded Temporary Hospital in India

During the COVID-19 pandemic, the total number of hospital beds in the National Capital Region (NCR) of Delhi was 54,321 (roughly 300 beds per one lakh population), which was inadequate for the patients. Therefore, the Indian government initiated the construction of a 1,000-bedded greenfield hangar-based hospital to bridge the healthcare gap. As a result, Intensive Care Unit (ICU) beds in the facility augmented the COVID-19 care ICU beds in the city by 11%. The authors were involved in the planning, developing, and initiating the functioning of 1,000-bedded Dedicated COVID-19 Hospital (DCH). The hospital was conceptualized, built, and operationalized in 12 days only. Lessons learned from this experience would be of benefit should similar situations arise in future. Coordinating structural designing early with the entire project team-from facility administrators and medical practitioners to architects, consultants, and contractors-can result in a structure that better matches the facility's long-term needs and often saves construction time and costs. This article enumerates various challenges faced and the way they were addressed. This hangar-based hospital can be rapidly constructed and deployed on a massive scale. While structural integrity is essential, the planning team was particularly aware of the patient-centric modality of healthcare. Many modifications were carried out in the structure based on patient inputs. Informal discussions with discharged patients and relatives revealed that the human-centric approach was the mainstay of the therapy.

Comparison of a Voiding Diary With Clinical Management Tool As an Outpatient Screening Tool for Childhood Functional Voiding Disorders

OBJECTIVE

To study the agreement of questionnaire-based assessment with voiding diary for differentiating primary mono-symptomatic nocturnal enuresis from voiding disorder in children.

METHOD

Children 5-12 years old with bedwetting after exclusion of secondary enuresis were enrolled and parents filled a clinical management tool (CMT) questionnaire and a 48-hours voiding diary. Point prevalence and agreement of classification as primary mono-symptomatic nocturnal enuresis or voiding disorder were compared.

RESULTS

Of 1276 children screened, 143 (11.2%) reported enuresis. Of 100 (82 males) children finally analyzed, constipation and positive family history occurred in 14% and 37%, respectively. Questionnaire-based assessment and voiding diary identified 65% and 71%, respectively as voiding disorder [Cohen's kappa 0.542 (95%CI: 0.367-0.717)]. Discordance of classification was noted in 20%. Voiding diary identified additional 7% cases of voiding disorder.

CONCLUSIONS

While CMT and voiding diary have moderate agreement, voiding diary should be used for cases screened negative by a questionnaire-based tool.

Vanishing White Matter Disease Presenting as Acute Febrile Encephalopathy: Case Report

A 3.5-year-old male child patient with mild developmental delay presented with history of acute onset fever, encephalopathy, and dyskinesia. The patient was investigated for common etiologies and was managed supportively. His neuroimaging was suggestive of vanishing white matter (VWM) disease which was confirmed by clinical exome sequencing. The child had an eventful hospital stay followed by near-total recovery after 4 weeks. The case attempts to sensitize readers about the current perspectives pertaining to VWM disease.

Pediatric Dystonic Storm: A Hospital-Based Study

Objective

Pediatric dystonic storm is an underrecognized entity. We aimed to evaluate the profiles of children presenting with dystonic storm in a referral hospital. Management schema and treatment responsiveness of this uncommonly reported entity were analyzed.

Methods

Retrospective review of all children (up to 18 years) hospitalized with dystonic storm over 39 months in the aforementioned facility.

Results

Twenty-three children whose ages ranged from 2 years 2 months to 14 years 4 months years (median: 6 years 11 months) (males: 13, females: 11) presented with dystonic storm. The annual incidence was 0.4 per 1,000 fresh admissions with an event rate of 0.9 per 1,000 for all admissions. All had Dystonia Severity Action Plan grades 4/5 with identifiable trigger in 13 (50%). Underlying dystonic disorder preexisted in 10 (43.4%); 8 of these had cerebral palsy. Polypharmacotherapy with >4 drugs out of trihexyphenidyl, tetrabenazine, clonazepam, gabapentin, levodopa-carbidopa, trichlorophos, and melatonin was needed. Supportive care and adequate sedation helped in symptom control. All children were managed with midazolam infusion over 2-10 days (median: 5 days). Mechanical ventilation was resorted to in 6 children (3-22 days). Vecuronium and propofol were used in 3/23 (13%) and 4/23 (17%) children, respectively. Deep brain stimulation was curative in 1 child. Hospitalization ranged from 5 to 31 (median: 11) days. Although there were no deaths, rhabdomyolysis was noted in 1 child. Postdischarge, 6 (26%) children relapsed.

Conclusions

Dystonic storm is a medical emergency mandating aggressive multimodal management. Supportive care, antidystonic drugs, and early elective ventilation alongside adequate sedation with benzodiazepines ameliorate complications. Relapses of dystonic storm are not uncommon.

Transcobalamin deficiency: vitamin B12 deficiency with normal serum B12 levels

Transcobalamin (TC) deficiency is a rare autosomal recessive inborn error of cobalamin transport which clinically manifests in early infancy. We describe a child with TC deficiency who presented with classical clinical and lab stigmata of inborn error of vitamin B₁₂ metabolism except normal serum B₁₂ levels. He was started on empirical parenteral cobalamin supplements at 2 months of age; however, the definitive diagnosis could only be established at 6 years of age when a genetic evaluation revealed homozygous nonsense variation in exon 8 of the TCN2 gene (chr22:g.31019043C>T).

Hemolytic uremic syndrome in a developing country: Consensus guidelines

BACKGROUND

Hemolytic uremic syndrome (HUS) is a leading cause of acute kidney injury in children. Although international guidelines emphasize comprehensive evaluation and treatment with eculizumab, access to diagnostic and therapeutic facilities is limited in most developing countries. The burden of Shiga toxin-associated HUS in India is unclear; school-going children show high prevalence of anti-factor H (FH) antibodies. The aim of the consensus meeting was to formulate guidelines for the diagnosis and management of HUS in children, specific to the needs of the country.

METHODS

Four workgroups performed literature review and graded research studies addressing (i) investigations, biopsy, genetics, and differential diagnosis; (ii) Shiga toxin, pneumococcal, and infection-associated HUS; (iii) atypical HUS; and (iv) complement blockade. Consensus statements developed by the workgroups were discussed during a consensus meeting in March 2017.

RESULTS

An algorithm for classification and evaluation was developed. The management of Shiga toxin-associated HUS is supportive; prompt plasma exchanges (PEX) is the chief therapy in patients with atypical HUS. Experts recommend that patients with anti-FH-associated HUS be managed with a combination of PEX and immunosuppressive medications. Indications for eculizumab include incomplete remission with plasma therapy, life-threatening features, complications of PEX or vascular access, inherited defects in complement regulation, and recurrence of HUS in allografts. Priorities for capacity building in regional and national laboratories are highlighted.

CONCLUSIONS

Limited diagnostic capabilities and lack of access to eculizumab prevent the implementation of international guidelines for HUS in most developing countries. We propose practice guidelines for India, which will perhaps be applicable to other developing countries.

Abstract P3-08-05: High APOBEC3C-H gene expression in tumor associates with better survival in breast cancer

Background

APOBEC3 (A3) enzymes are strong mutagenic factors. A3B has been well described as an active mutator in breast cancer, whereas the roles of the other APOBEC3s (A3A, C-H) are unclear. While mutations may directly drive cancer progression, they can indirectly suppress cancer growth by generating neoantigens. To elucidate this, we comprehensively analyzed all APOBEC3s for their association with mutations and immune activity in breast cancer.

Methods

RNA seq.-based gene expression data for 1091 primary carcinomas and 113 adjacent normal tissues was from TCGA. Patients were divided into high and low groups by top and bottom gene expression tertiles. Tumor immune features like cytolytic activity, T cell receptor (TCR) diversity, and cell fractions were quantified from gene expression data. Data for some of these features, mutation-related aspects, and survival outcomes were obtained from the Pan-Cancer Atlas. Gene expression data for 55 breast cancer cell-lines was from Cancer Cell Line Encycolpedia. Cox regression and Spearman methods were respectively used for survival and correlation analyses. Welch's t test was used for group comparison. P <0.05 was deemed significant. Hallmark gene-sets were used for enrichment analysis with recommended 25% FDR.

Results

A3B and A3C together represented most (91%) of A3 gene expression in breast cancer cell-lines. In TCGA patients, expression of only A3B was increased by 4.5x in tumors compared to normal tissue, whereas levels for other A3 genes were unchanged. Surprisingly, tumor A3B or A3A levels had no significant association with overall (OS) or disease-specific survival (DSS), whereas for each of A3C-H, higher expression was significantly associated with improved OS (hazard ratios of 0.45-0.66) or DSS (0.43-0.61). The prognostic benefit of high A3C-H expression was also seen in survival analyses of two meta-datasets of microarray-based gene expression (KMPlot and SurvExpress). A3A and A3B levels correlated with both mutation burden and neoantigen load (Spearman ρ = 0.28-0.34), which respectively were 2.0-2.9x higher in high compared to low expressors. But there was no association of expression with mutation burden or neoantigen load for A3C-H. On the other hand, A3C-H levels correlated positively with tumor leukocyte fraction (ρ = 0.29-0.70) and its lymphocyte subset (ρ = 0.20-0.50), whereas the correlation was poor for A3B (ρ = 0.10 & -0.01 respectively). Expression of genes of immune function like interferon response and complement activation was enriched in high A3C-H expressors. It was not so for A3B, for which enrichment was instead observed for cell proliferation. Both CD4 and CD8 T cells were significantly more (2.3-4.0x & 2.1-5.4x resp.), and TCR diversity significantly higher (1.3-2.1x) in A3C-H high expressors. Concordantly, for each of A3C-H, expression correlated with tumor immune cytolytic activity (ρ = 0.31-0.79), which was increased 3.1-7.9x in high compared to low expressors.

Conclusions

These findings suggest that in spite of A3C-H being known as DNA mutators, an increase in their expression confers a survival benefit in breast cancer. Their increased expression likely reflects a heightened anti-cancer immune response, and may be useful for disease prognosis and monitoring immunotherapy.

Can microRNA profiles predict corticosteroid responsiveness in childhood nephrotic syndrome? A study protocol

INTRODUCTION

In last few years, several studies have revealed the remarkable stability of extracellular microRNAs (miRNAs) circulating in the blood or excreted in the urine and underscored their key importance as biomarkers of certain diseases. Since miRNA in urinary sediment is relatively stable and easily quantified, it has the potential to be developed as a biomarker for disease diagnosis and monitoring. Identification of serum and urinary levels of certain miRNAs may assist in the diagnosis and assessment of disease activity in patients with nephrotic syndrome (NS). The global expression profile of miRNAs in childhood NS in Indian population remains unknown. Hence, further research is warranted in this area. This study seeks to prospectively evaluate whether a multipronged multiomics approach concentrating on microRNA expression profiles in children with NS vis-a-vis normal healthy children is discriminant enough to predict steroid responsiveness in childhood NS.

METHODS AND ANALYSIS

In this prospective multicentric cohort study, subjects will be recruited from general paediatric and paediatric nephrology outpatient departments (OPDs) in tertiary care level referral hospitals. Age-matched and sex-matched healthy individuals with normal renal function (as assessed by normal serum creatinine and normal ultrasound of kidneys, ureter and bladder) in 1:1 ratio between study and control groups will be recruited from among the healthy siblings of children presenting to the OPDs. Differential microRNA expression profiles in urine and serum samples of children with steroid-sensitive NS (SSNS) and steroid-resistant NS (SRNS) with healthy children will be compared in a two-phased manner: a biomarker discovery phase involving pooled samples across SSNS, SRNS and healthy siblings analysed in triplicate using next-generation sequencing, slide microarray and quantitative reverse transcriptase PCR (qRT-PCR) arrays covering human miRNome followed by a validation phase with customised qRT-PCR primers based on the concordance in the discovery phase differential expression profiles and bioinformatics analysis.

ETHICS AND DISSEMINATION

The study is funded after dueInstitutional Ethics Committee (IEC) clearance, and results will be available as open access.

Cardiovascular outcomes of Nephrotic syndrome in childhood (CVONS) study: a protocol for prospective cohort study

BACKGROUND

Nephrotic syndrome (NS) is characterized by dyslipidemia which is a well-known risk factor for atherogenesis. Atherosclerosis in childhood is mostly subclinical and endothelial dysfunction is known to precede this. Evidence for screening for endothelial dysfunction and cardiovascular risk factors and early identification of premature onset of atherosclerosis in childhood NS remains tenuous in the absence of well-designed prospective studies addressing cardiovascular comorbidity in NS. The objective of our study is to examine endothelial dysfunction and short-term cardiovascular outcomes in a carefully phenotyped cohort of patients with Nephrotic syndrome as compared to healthy controls.

METHODS

In a multi-centric prospective cohort study, 70 Steroid Resistant NS (SRNS), 70 Steroid Sensitive (SSNS) patients along with 70 Healthy Controls are being recruited. After a baseline assessment of functional and structural status of heart (2D Echocardiography), arteries (Carotid Doppler and Intima Media Thickness measurements) and microcirculation [a combination of 2D Echocardiography, Laser Doppler Flowmetry (LDF) and Brachial Artery Flow mediated dilation (FMD) and Nail Fold Capillaroscopy (NFC)], the patients are being investigated for endothelial dysfunction. Venous blood sample (15 ml) is being collected for routine investigations and assay of biochemical endothelial markers through Flow Cytometry. The patients will be followed up at 12 months and 24 months after the recruitment to look for any change from baseline period.

DISCUSSION

This study will able to provide a better understanding of the epidemiology of endothelial dysfunction and associated subclinical cardiovascular co-morbidity in childhood NS. Findings on characterization of prevalence of endothelial dysfunction and subclinical markers may be used to design future randomized controlled trials for evaluating the efficacy of preventive and therapeutic interventions in reducing the incidence of cardiovascular disease.

A long term follow-up study from India assessing the risk of diabetes mellitus in service population

OBJECTIVE

The data about the incidence of diabetes is scarce from developing countries. We studied the incidence of type 1 (T1DM) and type 2 DM (T2DM) in a cohort of young military personnel followed for a long duration.

METHODS

The data for this descriptive epidemiologic study was derived from the electronic medical records (EMR) of the male service personnel enrolled between 1990 and 2015. All subjects were recruited before 18 years of age in good health and the onset of DM was derived from the EMR. We calculated the incidence rates as per person years using appropriate statistical methods.

RESULTS

Our study population includes 51,217 participants (median age 33 years, range 17-54) with a mean follow up of 12.5 years, giving a cumulative follow up duration of 613,925 person-years (py). A total of 251 patients developed T2DM and 15 patients developed T1DM during the study period. The incidence rate of T2DM was 0.41 per 1000 py and that of T1DM was 2.44 per 100,000 py.

CONCLUSION

Our cohort had low incidence rates of diabetes when compared with other studies from India and abroad. Active military service with good life style measures may offer protection from the DM.

Incidence of parathyroid disorders in Indian adult male population: A 25-year follow-up study

CONTEXT AND OBJECTIVE

Detailed information on the epidemiology of parathyroid disorders in India is lacking. Most of the available data pertain to primary hyperparathyroidism (PHPT) rather than the overall burden of parathyroid disorders. We studied the incidence of parathyroid disorders in a cohort of service personnel followed for a long duration.

DESIGN, SETTING AND PATIENTS

The data for this retrospective, descriptive epidemiological study were derived from the electronic medical records (EMR) of health care personnel enrolled between 1990 and 2015. Subjects were recruited between the ages of 17 and 20 years in good health, and the data pertaining to parathyroid disorders were derived from the EMR.

MAIN OUTCOMES MEASURES

We calculated the incidence rates per person-years of parathyroid disorders using appropriate statistical methods.

RESULTS

Our analysis includes 51 217 participants (median age 33, range 17-54 years) with a mean follow-up of 12.5 years. Yearly evaluation of the data gave cumulative follow-up duration of 613 925 person-years. PHPT was diagnosed in 37 patients and hypoparathyroidism in 16 patients, giving incidence rates of 6 and 2.6 per 100 000 person-years, respectively. Only one patient was diagnosed with pseudohypoparathyroidism (0.16 per 100 000 person-years). Of the 37 patients with PHPT, 16 (43%) developed postsurgical hypoparathyroidism.

CONCLUSIONS

Our cohort had a low incidence of PHPT when compared to Western populations. Long-term epidemiological studies are essential to identify the demographic trends of metabolic bone disorders in India.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line-associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN.

Steroid responsive encephalopathy associated with autoimmune thyroiditis (SREAT) in childhood

AIM

Steroid responsive encephalopathy with autoimmune thyroiditis (SREAT) is a clinically and electrographically heterogeneous steroid-responsive encephalopathy associated with thyroid autoantibodies. We report an adolescent with SREAT and review PubMed literature relating to childhood.

METHODS

A 14-year-old boy, without any preceding history of trauma, meningoencephalitis or seizures, was admitted in a comatose state. A similar episode of loss of consciousness 2 months prior with normal neuroimaging and electroencephalogram (EEG) had been followed by behavioral alterations. A year previously, during evaluation for increased appetite and poor weight gain, he was noted to have small goitre with thyroid-stimulating hormone (TSH) 7.26 mIU/L, T3 1.232 nmol/L, and T4 117.63 nmol/L. Routine hemogram, blood biochemistry, thyroid function tests including free hormone levels, ultrasonography thyroid and magnetic resonance imaging were normal. EEG showed diffuse slowing of all waves. Cerebrospinal fluid showed no pleocytosis and electrophoresis showed oligoclonal band. Viral studies and serum N-methyl-D-aspartate receptor antibody levels were negative. Anti-thyroid peroxidase (Anti-TPO) antibodies were raised. Intervention was with intravenous dexamethasone 4 mg every 6 h for 1 week followed by tapering schedule of oral prednisolone over 6 months.

RESULTS

He regained consciousness after the second dose of dexamethasone and was discharged on day 7 in a fully conscious and ambulant state on a tapering course of low dose prednisolone for 6 months. He remains euthyroid with normal sensorium and behavior at 18 months follow-up. Only 50 cases below 18 years age were identified amongst 300 PubMed articles up to 31 July 2013.

CONCLUSION

Prompt steroid therapy following early recognition by high clinical suspicion and measurement of antithyroid antibody titers can lead to a favorable prognosis in SREAT.

Amniotic Band Sequence - A Debilitating Syndrome

A male baby was delivered by Caesarean section at term to a 35 years second gravida lady with fibroid uterus. The mother was booked and immunized and not on any medication. Antenatal and natal periods including serial ultrasounds were normal. At birth the neonate was observed to have multiple grooves over ring & middle index finger of left hand and hypoplasia of left little finger. Both great toes were amputated. In view of asymmetrical involvement, presence of amniotic bands, no other organ involvement and sporadic nature, he was diagnosed as a case of amniotic band sequence. Congenital amputations should be distinguished from congenital hypoplasia and/or aplasia. Differentiation is important for genetic counselling and evaluation of the risk of recurrence. Keywords: Amniotic Bands, Intrauterine Amputation, Intrauterine Constriction Rings.

An unusual cause of delayed puberty: Berardinelli- Seip syndrome

Berardinelli- Seip syndrome is an autosomal recessive disorder characterized by generalized lipoatrophy, extreme insulin resistance with dyslipidemia in childhood and development of diabetes in adolescence. Menstrual irregularities are commonly seen as a result of secondary polycystic ovarian syndrome. Delayed puberty as a manifestation of these abnormalities in girls has rarely been described earlier. We report one such case patient who had delayed puberty and portal hypertension as unique features amongst the characteristic phenotypes of this syndrome.

Meconium Aspiration Syndrome: An Insight

Meconium aspiration syndrome (MAS) is respiratory distress in a newborn baby caused by the presence of meconium in the tracheobronchial airways. The aspiration of meconium stained amniotic fluid by the fetus can happen during antepartum or intrapartum periods and can result in airway obstruction, interference with alveolar gas exchange, chemical pneumonitis as well as surfactant dysfunction. These pulmonary effects cause gross ventilation-perfusion mismatching. To complicate matters further, many infants with MAS have primary or secondary persistent pulmonary hypertension of the newborn as a result of chronic in utero stress and thickening of the pulmonary vessels. Although meconium is sterile, its presence in the air passages can predispose the infant to pulmonary infection. MAS is essentially a clinical diagnosis and should always be suspected in a child with respiratory distress and meconium-stained amniotic fluid at delivery. Though a known entity for a long time, its management still remains contentious. Intubation and direct tracheal suction is performed when meconium is observed in the amniotic fluid and the infant is not vigorous. Subsequent management involves ventilation, surfactant instillation and lavage, inhaled nitric oxide and high frequency ventilation. The role of steroids continues to be controversial.

Unilateral palatal palsy with viral hepatitis

Isolated unilateral palatal (velopalatopharyngeal) palsy is a clinical rarity. This usually presents in a child as acute onset rhinolalia, unilateral absent palatal reflex and pharyngeal asymmetry with a benign self-resolving course. Etiology remains controversial. We report association of this entity in a male child with viral hepatitis A.

Efficacy of Nebulised Epinephrine versus Salbutamol in Hospitalised Children with Bronchiolitis

BACKGROUND

The use of bronchodilators in bronchiolitis lacks consensus. The efficacy of nebulised epinephrine versus salbutamol in bronchiolitis and the safety profile of the bronchodilators was studied.

METHODS

Effects of nebulised epinephrine and salbutamol were compared in children with moderate to severe acute bronchiolitis. Thirty children between 2 to 24 months of age were recruited, 15 in each treatment group. Children received periodic (0,30,60 minutes followed by 4 hourly) doses of either 1:1000 laevo- epinephrine (0.5ml/kg subject to a maximum of 2.5ml with 3ml saline) or salbutamol (0.15mg/kg with 3ml saline) via nebuliser with oxygen. Changes in heart rate (HR), respiratory rate (RR), respiratory distress assessment instrument (RDAI), oxygen saturation (SpO2), oxygen requirement, duration of hospital stay and the side effects were studied.

RESULTS

The respiratory status was better with significant improvement in RR, RDAI score and SpO2, decreased oxygen requirement and shorter hospital stay in the epinephrine group. There were no significant side effects in either group.

CONCLUSION

Nebulised epinephrine is a useful and safe drug for moderate/severe bronchiolitis and is superior to salbutamol.

An outbreak of dengue fever in Veerannapet village, Cherial Mandal, of Warangal district, Andhra Pradesh

An epidemiological and entomological investigation was carried out in Veerannapet village, Cherial Mandal of Warangal district, Andhra Pradesh. The study showed that all age groups and both the sexes were affected with the disease. Fever and bodyache was the first presenting feature, which was self-limiting and lasted for 4-5 days. Of the 19 Serum Samples tested, 17 showed high titre to Dengue antigen with 10 showing diagnostic titre. Five samples were positive for IgM antibodies to dengue virus. Larval surveys indicates high Breteau index (30.40%), House index (23.20%) and Container index (9.17%). The clinico-epidemiological and entomological investigation indicates present episode of fever outbreak is due to dengue fever. Strengthening and intensification of surveillance along with educating the community is recommended for prevention of outbreak.

Breeding habitats and larval indices of Aedes aegypti (L) in residential areas of Rajahmundry town, Andhra Pradesh

Entomological studies on relative prevalence and distribution of adults and immatures of Aedes aegypti were conducted in Rajahmundry town of Andhra Pradesh from December 1998 to November 1999. Adults and immature stages of Aedes aegypti were found in all the 22 localities viz; posh area (8), mixed area (8) and slum area (6) of the town. Larval indices were found to be higher in slum areas as compared to mixed or posh areas of the town. However, the larval habitats were observed to be similar in all localities. The larval indices were highest during monsoon and post-monsoon months. The breeding preference ratio (BPR) was highest for cement tubs followed by discarded tyres and barrels. The high larval indices of Aedes aegypti in these areas warrant intensification of vector surveillance activities along with source reduction and health education.

Community studies on hepatitis B in Rajahmundry town of Andhra Pradesh, India, 1997-8: unnecessary therapeutic injections are a major risk factor

In Rajahmundry town in India, 234 community cases of jaundice were interviewed for risk factors of viral hepatitis B and tested for markers of hepatitis A-E. About 41% and 1.7% of them were positive for anti-HBc and anti-HCV respectively. Of 83 cases who were tested within 3 months of onset of jaundice, 5 (6%), 11 (13.3%), 1 (1.2%), 5 (6%) and 16 (19.3%) were found to have acute viral hepatitis A-E, respectively. The aetiology of the remaining 60% (50/83) of cases of jaundice could not be established. Thirty-one percent (26/83) were already positive for anti-HBc before they developed jaundice. History of therapeutic injections before the onset of jaundice was significantly higher in cases of hepatitis B (P = 0.01) or B-D (P = 0.04) than in cases of hepatitis A and E together. Other potential risk factors of hepatitis B transmission were equally prevalent in two groups. Subsequent studies showed that the majority of injections given were unnecessary (74%, 95% CI 66-82%) and were administered by both qualified and unqualified doctors.

alpha(1,3)fucosyltransferases expressed by the gain-of-function Chinese hamster ovary glycosylation mutants LEC12, LEC29, and LEC30

Gain-of-function glycosylation mutants provide access to glycosylation pathways, glycosylation genes, and mechanisms that regulate expression of a glycotype. Previous studies have shown that the gain-of-function Chinese hamster ovary (CHO) mutants LEC12, LEC29, and LEC30 express an N-ethylmaleimide-resistant alpha(1, 3)fucosyltransferase (alpha(1,3)Fuc-T) activity that is not detected in CHO cells and that generates the Lewis(X) but not the sialyl-Lewis(X) determinant. The three mutants differ, however, in lectin resistance properties, expression of fucosylated antigens, and in vitro alpha(1,3)Fuc-T activities. In this paper we show that each mutant expresses Fuc-TIX, but only LEC30 cells express Fuc-TIV. Using genomic PCR and reverse-transcriptase (RT)-PCR strategies, we isolated coding portions of the CHO Fut4 and Fut9 genes. Each gene is present in a single copy in the CHO and mutant genomes. The Fut4 gene is expressed only in LEC30 cells, while all three mutants express the Fut9 gene. Interestingly, the fucosylation phenotypes of LEC12 and LEC29 cells do not correlate with the relative abundance of their Fut9 gene transcripts (LEC29 >> LEC12). Compared to LEC29 cells, LEC12 cells have an approximately 40-fold higher in vitro alpha(1,3)Fuc-T activity and bind the VIM-2 monoclonal antibody, whereas LEC29 cells do not bind VIM-2. Mixing experiments did not detect Fuc-TIX inhibitory activity in LEC29 cell extracts, and CHO cells expressing a transfected Fut9 gene behaved like LEC12 cells. Therefore, it seems that LEC29 cells may not translate their more abundant Fut9 gene transcripts efficiently or may not synthesize appropriate acceptors for internal alpha(1,3)fucosylation. Alternatively, LEC12 cells may possess, in addition to Fuc-TIX, a novel alpha(1,3)Fuc-T activity.

Community studies on prevalence of HBsAg in two urban populations of southern India

OBJECTIVE

To find out prevalence of HBsAg in general population, especially in under-five children.

SETTING

Bangalore and Rajahmundry towns in southern India.

METHODS

Localities were chosen as the sampling units in each town. About 10-20 households were randomly selected from each locality. Only the youngest but apparently healthy person present in the household was interviewed for age, sex and history of jaundice any time in life. Mothers were interviewed to collect data for children below 15 years of age. Blood samples were collected from these persons on filter paper strips (18-mm diameter disc, Whatman filter paper No. 3) by finger prick method. The samples were tested for HBsAg by Micro ELISA (Ortho-Clinical Diagnostics).

RESULTS

Overall, 3.3% (95% CI, 2.0-4.5) of 737 persons in Rajahmundry and 4.2% (95% CI, 2.8-5.5) of 816 persons in Bangalore were found carriers of HBsAg. Age-specific or sex specific carrier rates were similar in Rajahmundry as well as in Bangalore. Most of the carriers (96%) denied having jaundice ever in life.

CONCLUSIONS

The results from this community based study are in agreement with the historical data from hospital based studies that about 3-5% of persons may be carriers of HBsAg and that the pool of chronic carriers of hepatitis B virus in India is built up in childhood and is then maintained in older children and adults. The results highlight the need of completing hepatitis B immunization during the infancy.

Some aspects of the bionomics of Culex quinquefasciatus (Diptera: Culicidae) in Rajahmundry town, Andhra Pradesh

From January 1991 to December 1992 the adult and immature populations of Culex quinquefasciatus were monitored in selected localities of Rajahmundry town. The larval density per dip ranged from 1.1 in September to 25.3 in October and the pupal density from 1.2 to 8.4 in October. Two high peaks of adult density in a year were observed during the study. Infective mosquitoes were recorded only in November 1991 and August 1992. Cx. quinquefasciatus landing on human bait was maximum between 2200 to 2400 hours and they preferred to land on body site followed by legs, hands and face in that order. The anthropophilic index was 79.5 per cent. Ratio of Female: Male mosquitoes was 5:1.

Effect of covalent attachment of polyethylene glycol on some properties of rat liver soluble alanine aminotransferase

Soluble alanine aminotransferase from rat liver was modified with 2,4-bis(O-methoxypolyethylene glycol)-6-chloro-s-triazine which was synthesized from monomethoxypolyethylene glycol and cyanuric chloride. The modified enzyme exhibited relative stability against extreme conditions of pH and temperature and also resistivity against tryptic digestion as compared to the native enzyme.

Acute respiratory infection in children--a survey in East Godavari district of Andhra Pradesh

A survey was carried out in East Godavari district of Andhra Pradesh to determine the magnitude of the problem of Acute Respiratory Infection (ARI) in children below five years of age. ARI associated mortality rates were found to be 15 times higher in infants than in the 1-4 year age group. However, overall ARI associated mortality was only 2.01 per thousand with an estimated case fatality ratio of 0.4 per thousand. A reverse trend in morbidity was noted in which 2-week incidence of ARI was more in 1-4 years age group than in infants. There is a need to standardize diagnosis and treatment of ARI disease in the district in order to eliminate wasteful use of antibiotics.
