Diagnosis, Treatment and Prevention of Nutritional Anemia in Children: Recommendations of the Joint Committee of Pediatric HematologyOncology Chapter and Pediatric and Adolescent Nutrition Society of the Indian Academy of Pediatrics

Justification: Anemia in children is a significant public health problem in our country. Comprehensive National Nutrition Survey 2016-18 provides evidence that more than 50% of childhood anemia is due to an underlying nutritional deficiency. The National Family Health Survey-5 has reported an increase in the prevalence of anemia in the under-five age group from 59% to 67.1% over the last 5 years. Clearly, the existing public health programs to decrease the prevalence of anemia have not shown the desired results. Hence, there is a need to develop nationally acceptable guidelines for the diagnosis, treatment and prevention of nutritional anemia. Objective: To review the available literature and collate evidence-based observations to formulate guidelines for diagnosis, treatment and prevention of nutritional anemia in children. Process: These guidelines have been developed by the experts from the Pediatric Hematology-Oncology Chapter and the Pediatric and Adolescent Nutrition (PAN) Society of the Indian Academy of Pediatrics (IAP). Key areas were identified as: epidemiology, nomenclature and definitions, etiology and diagnosis of iron deficiency anemia (IDA), treatment of IDA, etiology and diagnosis of vitamin B12 and/or folic acid deficiency, treatment of vitamin B12 and/or folic acid deficiency anemia and prevention of nutritional anemia. Each of these key areas were reviewed by at least 2 to 3 experts. Four virtual meetings were held in November, 2021 and all the key issues were deliberated upon. Based on review and inputs received during meetings, draft recommendations were prepared. After this, a writing group was constituted which prepared the draft guidelines. The draft was circulated and approved by all the expert group members. Recommendations: We recommend use of World Health Organization (WHO) cut-off hemoglobin levels to define anemia in children and adolescents. Most cases suspected to have IDA can be started on treatment based on a compatible history, physical examination and hemogram report. Serum ferritin assay is recommended for the confirmation of the diagnosis of IDA. Most cases of IDA can be managed with oral iron therapy using 2-3 mg/kg elemental iron daily. The presence of macro-ovalocytes and hypersegmented neutrophils, along with an elevated mean corpuscular volume (MCV), should raise the suspicion of underlying vitamin B12 (cobalamin) or folic acid deficiency. Estimation of serum vitamin B12 and folate level are advisable in children with macrocytic anemia prior to starting treatment. When serum vitamin B12 and folate levels are unavailable, patients should be treated using both drugs. Vitamin B12 should preferably be started 10-14 days ahead of oral folic acid to avoid precipitating neurological symptoms. Children with macrocytic anemia in whom a quick response to treatment is required, such as those with pancytopenia, severe anemia, developmental delay and infantile tremor syndrome, should be managed using parenteral vitamin B12. Children with vitamin B12 deficiency having mild or moderate anemia may be managed using oral vitamin B12 preparations. After completing therapy for nutritional anemia, all infants and children should be advised to continue prophylactic iron-folic acid (IFA) supplementation as prescribed under Anemia Mukt Bharat guidelines. For prevention of anemia, in addition to age-appropriate IFA prophylaxis, routine screening of infants for anemia at 9 months during immunization visit is recommended.

Pediatric Appropriate Evaluation Protocol for India (PAEP-India): Tool for Assessing Appropriateness of Pediatric Hospitalization

Objectives: To develop and assess Pediatric AppropriatenessEvaluation Protocol for India (PAEP-India) for inter-rater reliabilityand appropriateness of hospitalization.Design: Cross-sectional study.Setting: The available PAEP tools were reviewed and adaptedfor Indian context by ten experienced pediatricians followingsemi-Delphi process. Two PAEP-India tools; newborn (?28 days)and children (>28 days-18 years) were developed. These PAEP-India tools were applied to cases to assess appropriateness ofadmission and inter-rater reliability between assessors.Participants: Two sets of case records were used: (i) 274cases from five medical colleges in Delhi-NCR [?28 days (n=51);>28 days to 18 years (n=223)]; (ii) 622 infants who werehospitalized in 146 health facilities and were part of a cohort (n=30688) from two southern Indian states.Interventions: Each case-record was evaluated by twopediatricians in a blinded manner using the appropriate PAEP-India tools, and ‘admission criteria’ were categorized asappropriate, inappropriate or indeterminate.Main outcome measures: The proportion of appropriatehospitalizations and inter-rater reliability between assessors(using kappa statistic) were estimated for the cases.Results: 97.8% hospitalized cases from medical colleges werelabelled as appropriate by both reviewers with inter-rateragreement of 98.9% (k=0.66). In the southerm Indian set ofinfants, both reviewers labelled 80.5% admissions as appropriatewith inter-rater agreement of 96.1% (k= 0.89).Conclusions: PAEP-India (newborn and child) tools are simple,objective and applicable in diverse settings and highly reliable.These tools can potentially be used for deciding admissionappropriateness and hospital stay and may be evaluated later forusefulness for cost reimbursements for insurance proposes.

Differential Histone Acetylation in Sub-Regions of Bed Nucleus of the Stria Terminalis Underlies Fear Consolidation and Extinction

OBJECTIVE: The hallmark of anxiety disorders is excessive fear. Previous studies have suggested that selective neural projections from Basal nucleus of stria terminalis (BNST) to amygdala and vice-versa precisely control the fear learning process. However the exact mechanism how the BNST controls fear consolidation and its extinction is largely unknown. In the present study we observed the changes in the BNST sub-regions following fear conditioning and its extinction. METHODS: The change in the number of positive neurons was determined by immunohistochemistry for Acetyl H3 (Histone 3), Acetyl H4 (Histone 4), cAMP response element binding Protein (CBP) and c-fos in three sub-regions of the BNST namely the anterio-lateral BNST (STLP) and anterio-medial BNST (STMA), and lateral-ventral BNST (STLV) of rats subjected to auditory fear conditioning and extinction. RESULTS: We found significant increase in the number of CBP, acetyl H3 and acetyl H4 positive neurons in the STMA and STLV but not in the STLP after fear conditioning. However, following fear extinction the number of CBP, acetyl H3 and acetyl H4 positive neurons increased significantly in the STLP but not in the STMA and STLV. Similar changes were observed in the number of c-fos positive neurons after fear consolidation and extinction. CONCLUSION: The results from this study suggest that the differential histone acetylation in the different sub-regions of the BNST following fear learning and its extinction may be responsible for changes in the neuronal activation patterns resulting in either fear or less fear.

First description of SHV‑148 mediated extended‑spectrum cephalosporin resistance among clinical isolates of Escherichia coli from India.

Purpose: The present study was aimed to investigate the genetic context, association with IS26 and horizontal transmission of SHV‑148 among Escherichia coli in Tertiary Referral Hospital of India. Methodology: Phenotypic characterisation of extended‑spectrum beta‑lactamases (ESBLs) was carried out as per CLSI criteria. Molecular characterisation of blaSHV and integron was carried out by polymerase chain reaction (PCR) assay and confirmed by sequencing. Linkage of IS26 with blaSHV‑148 was achieved by PCR. Purified products were cloned on pGEM‑T vector and sequenced. Strain typing was performed by pulsed field gel electrophoresis with XbaI digestion. Transferability experiment and antimicrobial susceptibility was performed. Results: A total of 33 isolates showed the presence of SHV‑148 variant by sequencing and all were Class 1 integron borne. PCR and sequencing results suggested that all blaSHV‑148 showed linkage with IS26 and were present in the upstream portion of the gene cassette and were also horizontally transferable through F type of Inc group. Susceptibility results suggest that tigecycline was most effective. Conclusion: The present study reports for the first time of SHV‑148 mediated extended spectrum cephalosporin resistance from India. Association of their resistance gene with IS26 and Class 1 integron and carriage within IncF plasmid signifies the potential mobilising unit for the horizontal transfer.

Mirizzi's syndrome: lessons learnt from 169 patients at a single center

BACKGROUNDS/AIMS: Mirizzi's syndrome (MS) poses great diagnostic and management challenge to the treating physician. We presented our experience of MS cases with respect to clinical presentation, diagnostic difficulties, surgical procedures and outcome. METHODS: Prospectively maintained data of all surgically treated MS patients were analyzed. RESULTS: A total of 169 MS patients were surgically managed between 1989 and 2011. Presenting symptoms were jaundice (84%), pain (75%) and cholangitis (56%). Median symptom duration s was 8 months (range, <1 to 240 months). Preoperative diagnosis was possible only in 32% (54/169) of patients based on imaging study. Csendes Type II was the most common diagnosis (57%). Fistulization to the surrounding organs (bilio-enteric fistulization) were found in 14% of patients (24/169) during surgery. Gall bladder histopathology revealed xanthogranulomatous cholecystitis in 33% of patients (55/169). No significant difference in perioperative morbidity was found between choledochoplasty (use of gallbladder patch) (15/89, 17%) and bilio-enteric anastomosis (4/28, 14%) (p=0.748). Bile leak was more common with choledochoplasty (5/89, 5.6%) than bilio-enteric anastomosis (1/28, 3.5%), without statistical significance (p=0.669). CONCLUSIONS: Preoperative diagnosis of MS was possible in only one-third of patients in our series. Significant number of patients had associated fistulae to the surrounding organs, making the surgical procedure more complicated. Awareness of this entity is important for intraoperative diagnosis and consequently, for optimal surgical strategy and good outcome.

Emergence of integron borne PER-1 mediated extended spectrum cephalosporin resistance among nosocomial isolates of Gram-negative bacilli.

Background & objectives: Pseudomonas extended resistant (PER) enzymes are rare type of extended-spectrum beta lactamases (ESBLs) that confer third generation cephalosporin resistance. These are often integron borne and laterally transmitted. The aim of the present study was to investigate the emergence of integron borne cephalosporin resistant PER-1 gene in diverse incompatibility (Inc) group plasmids among gram-negative bacteria. Methods: a total of 613 consecutive, non-duplicate, Gram-negative bacteria of Enterobacteriaceae family and non-fermenting Gram-negative bacteria were isolated from different clinical specimens during a period of 18 months. For amplification and detection of blaPER, multiplex PCR was done. For understanding the genetic environment of blaPER-1, integrase gene PCR and cassette PCR (59 be) was performed. Gene transferability experiment was carried out and PCR based replicon typing was performed for incompatibility group typing of plasmids using 18 pairs of primers. An inhibitor based method was used for phenotypic detection of intrinsic resistance. Results: Multiplex PCR and sequencing confirmed that 45 isolates were harbouring blaPER-1. Both class 1 and class 2 integrons were observed among them. Integrase and cassette PCR (59 be) PCR results confirmed that the resistant determinant was located within class 1 integron. Transformation and conjugation experiments revealed that PER-1 was laterally transferable and disseminated through diverse Inc plasmid type. Efflux pump mediated carbapenem resistance was observed in all isolates. All isolates belonged to heterogenous groups. Interpretation & conclusions: This study demonstrates the dissemination of cephalosporins resistant, integron borne blaPER-1 in hospital setting in this part of the country and emphasizes on the rational use of third generation cephalosporins to slow down the expansion of this rare type of ESBL gene.

A rare cause of kyphosis with low backache - “Scheuermann’s disease”: “Osteochondritis deformans juvenilis dorsi.

An uncommon case of Scheuermann‟s disease (Apprentice‟s spine) is being reported for two simple reasons- firstly, to show that it is a self-limiting disease which needs only proper observation, extension exercises & extension spinal brace and secondly, it becomes a diagnostic riddle when osteolytic lesion is seen in epiphyseal plates of adjacent vertebral bodies in an adolescent. Radiology and Imaging are needed for the early and accurate diagnosis and to differentiate it from other causes of kyphosis. Hence, it stressed the need to publish this condition not only for its rarity but also for its diagnostic puzzle to differentiate it from other conditions. Here we report a case of an adolescent male of 17 years with poor posture/slouching, fatigue, mild pain in lower thoracic area of spine (low backache), stiffness and loss of flexibility with radiological and MRI findings.

Risk Factors for Development of Biliary Stricture in Patients Presenting with Bile Leak after Cholecystectomy

BACKGROUND/AIMS: This study was aimed at determining the factors associated with the development of benign biliary stricture (BBS) in patients who had sustained a bile duct injury (BDI) at cholecystectomy and developed bile leaks. METHODS: A retrospective analysis of 214 patients with BDI who were referred to our center between January 1989 and December 2009 was done. RESULTS: One hundred fifty-three (71%) patients developed BBS (group I), and 61 (29%) were normal (group II). By univariate analysis, female gender (p=0.02), open cholecystectomy as the index operation (p=0.0001), delay in the referral from identification of injury (p=0.04), persistence of an external biliary fistula (EBF) beyond 4 weeks (p=0.0001), EBF output >400 mL (p=0.01), presence of jaundice (p=0.0001), raised serum total bilirubin level (p=0.0001), raised serum alkaline phosphatase level (p=0.0001), and complete BDI (p=0.0001) were associated with the development of BBS. Furthermore, open cholecystectomy as the index operation (p=0.04), delayed referral (p=0.02), persistent EBF (p=0.03), and complete BDI (p=0.001) were found to predict patient outcome in the multivariate analysis. CONCLUSIONS: For the majority of patients with BDI, the risk of developing BBS could have been predicted at the initial presentation.

Lipodystrophy and metabolic complications of highly active antiretroviral therapy.

Objective. To assess the metabolic drug toxicities of first-line, World Health Organization (WHO)-recommended generic highly active antiretroviral therapy (HAART) regimens, to estimate the prevalence of body fat redistribution and to identify associated risk factors. Methods. Cross- sectional observational study. During 3 month period, 52 HIV infected children (25 on HAART; 27 not on HAART) were assessed. Their sociodemographic, clinical, and immunological data was recorded. Children were examined or the signs of fat redistribution (peripheral lipoatrophy and central lipohypertrophy). Liver function tests, fasting blood sugar, lipid profile, serum amylase, serum lactate, blood pH and bicarbonate levels were done in all patients. Results. Twenty-two patients were on stavudine and three on zidovudine based HAART. None of the patients ever received any protease inhibitor. There were no cases of clinical or immunological failure. Children on HAART had significantly lower weight for age and body mass index but the mean height for age was similar between study groups. Only two cases of peripheral lipoatrophy were observed. Hypercholesterolemia was observed in four children on HAART but none without therapy. Hypertriglyceridemia was observed in three children on HAART and seven without therapy. Four cases of asymptomatic mild hyperlactatemia were observed. No case of any hyperglycemia or liver impairment was observed. Conclusion. Metabolic abnormalities and lipodystrophy are emerging complications of HAART in Indian children and needs very close follow up. Future studies with larger sample size and longitudinal model are recommended.

Cystic lymphangiomatous hamartoma masquerading as massive ascites.

We report a 4-year-old boy presenting with a tense massive ascites and large hydrocele. History and physical examination were unremarkable. Routine laboratory studies were normal. Abdominal ultrasonography revealed massive ascites. Contrast CT was suggestive of a large cyst covering the entire peritoneal cavity. At laparotomy, a large cystic tumor was found extending into the scrotum through the left inguinal ring. Histopathologic examination diagnosed the tumor as a cystic lymphangiomatous hemartoma. Although abdominal lymphangiomas are seen in children, but presenting as massive ascites with hydrocele is very rare.

Caspofungin.

Caspofungin is a new antifungal drug meant for intravenous use. It has been shown to be comparable to other antifungal agents such as amphotericin B and fluconazole for empirical therapy in febrile neutropenic patients, oropharyngeal/esophageal candidiasis and invasive aspergillosis. Its efficacy has also been documented in children in small uncontrolled trials. The biggest assets of caspofungin are its excellent tolerability/safety profile and minimal drug interactions.

Comparative studies of different organs of Nyctanthes arbortristis in modulation of cytokines in murine model of arthritis / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To study the modulation effect of pro- and anti-inflammatory cytokines following long term use of water soluble ethanol extracts from different organs of Nyctanthes arbortristis (NAT) in mouse model of arthritis.</p><p><b>METHODS</b>Arthritis was induced in mice by two injections of Freund's complete adjuvant on days 0 and 12 in the sub-planter surface of the right hind paw.</p><p><b>RESULTS</b>Injection of adjuvant resulted in a maximum primary edema of the footpad with erythema, and edema and distortion of joints of the right hind paw after 24-48 hours. Second injection of FCA led to the formation of secondary swellings persisting more than four weeks that spread onto the other hind limb but to a lesser extent. Histological analysis of the ankle on day 47 showed marked evidence of cartilage destruction in association with pannus formation and moderate bone resorption. Proinflammatory cytokine levels in the inflamed joint homogenate were elevated on days 2, 14, and 47. Oral administration of leaf and fruit extracts in arthritic mice reduced joint homogenate levels of tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6 on days 2, 14, and 47 in comparison to untreated arthritic mice. Interleukin-10 level was elevated in the inflamed joint on days 2, 14, and 47 in comparisons to untreated arthritic mice.</p><p><b>CONCLUSION</b>Evidence of lesser inflammation of the footpad and joint and associated histological observation support the therapeutic benefit of leaf and fruit extracts from Nyctanthes arbortristis. This study helps in understanding the mechanism of anti-inflammatory action of Nyctanthes arbortristis in the light of pro- and anti-inflammatory cytokine balance.</p>
