A clinical association between exacerbation of asthma symptoms and Mycoplasma pneumoniae ( M. pneumoniae) infection has long been suspected. We studied 80 children aged 5-15 years; 50 with asthma (Group 1) and 30 without an acute exacerbation of asthma (Group 2) for detection of M. pneumoniae by serology and polymerase chain reaction (PCR) on nasopharyngeal aspirates. Our study confirms that lower respiratory tract infections with M. pneumoniae are frequently associated with exacerbations of asthma in children. [ABSTRACT FROM AUTHOR]

Midarm to head circumference ratio was evaluated in 233 term infants for identification of intrauterine growth retardation (IUGR) at birth. A ratio of 0.233±0.014 could identify all babies with severe IUGR, while all but two babies with mild I UGR had this ratio less than 0.280. The observation suggest that this method can be utilised for easy diagnosis of IUGR even by paramedical workers at community level, and is independent of ethnic groups or intrauterine growth curves.

Glomerulonephritis develops in about 20% patients with infective endocarditis (IE), but is mostly asymptomatic. Heavy proteinuria or derangement of kidney functions is uncommon. We report here a child with IE and proliferative glomerulonephritis who manifested as significant proteinuria that recovered on treatment with immunosupressants. [ABSTRACT FROM AUTHOR]

Congenital anomalies of kidney and urinary tract (CAKUT) are important causes of chronic kidney disease (CKD) in childhood. Most do not have a definite identifiable genetic defect and occur in isolation. Rarely, familial occurrence of CAKUT has been reported. The burden of CKD to a family in a developing country is enormous, and if more than one child is afflicted with the condition, the situation is almost catastrophic. We present here two families with siblings having upper and lower urinary tract obstruction. [ABSTRACT FROM AUTHOR]

Background & objectives: Mycoplasma pneumoniae is known to be a major cause of lower respiratory tract infections in children. A specific diagnosis is important to institute the appropriate treatment. Information on diagnostic methods used for M. pneumoniae in Indian paediatric population is scarce. The study was thus conducted to compare polymerase chain reaction (PCR), culture and serology for the diagnosis of M. pneumoniae in community-acquired lower respiratory tract infections in children. Methods: Seventy five children aged 6 months to 12 yr with signs of community-acquired lower respiratory tract infections were selected for the study. Culture of nasopharyngeal aspirates was done. The serum samples were analyzed for the detection of IgM and IgG antibodies to M. pneumoniae. A 543 base pairs (bp) region of PI gene of M. pneumoniae was selected for amplification in PCR assay applied to nasopharyngeal aspirates. Results: M. pneumoniae was isolated in culture from 4 (5.33%) children. Serological evidence of M. pneumoniae infection was observed in 16121.3 % I children. All culture positive patients were also positive by serology. Overall, PCR for M. pneumoniae was positive in 13 (17.3%) patients. All four culture positive patients were also positive by PCR. In 11 out of 13 (84.62%) PCR positive patients, serological evidence was there. Culture and for seralogy and/or PCR positive results diagnosed M. pneumoniae infection in 18 (24%) of 75 patients. Interpretatation & conclusions: A combination of culture, serology and PCR may provide diagnostic information on the aetiology of M. pneumoniae community-acquired lower respiratory tract infections in paediatric population.

Background: Mycoplasma pneumoniae plays a significant role in lower respiratory tract infections (LRTIs) in children. The aim of this study was to investigate the role of M. pneumoniae in communityacquired LRTIs in children, with use of both serological tests and PCR analysis. Methods & Materials: A total of 100 patients 6 months to 12 years of age with acute lower respiratory tract infections were enrolled for this study. These patients were investigated clinically and radiologically. Sera were used for detecting IgM and IgG antibodies to M. pneumoniae by ELISA. PCR to amplify fragments in the 16srDNA gene of M. pneumoniae was conducted employing throat swab samples. Results: In the present study, there were 61(61%) male and 39(39%) female children had LRTIs but no statistical significant association was found between sex of the patient and incidence of M pneumoniae infection.(p = 0.42). Eighteen(60%) patients were positive forMpneumoniae in the age group of ≤5 years and 12(40%) patients of ≥5 years of age were positive for M. pneumoniae but this difference was found to be statistically significant.(p = 0.02). The clinical and radiological profile across M.pneumoniae positive and negative cases were comparable. Serological evidence of acute infection was observed in 28(28%) patients. PCR was positive in throat swab samples of 6(6%) patients; 4(66.6%) patients with serologically proven and 2(33.3%) serological unproven. Together, serology and/or PCR detected thirty (30%) patients M.pneumoniae infection. Conclusion: In conclusion, our data underline the role of M. pneumoniae in children with community-acquired LRTIs, even in children aged < 5 years. [ABSTRACT FROM AUTHOR]

This study was designed to evaluate the incidence of Mycoplasma pneumoniae infection in children with community-acquired lower respiratory tract infections (LRTIs). A total of 245 patients 6 months to 12 years of age were investigated for M. pneumoniae employing serological tests, polymerase chain reaction (PCR), nested PCR, and reverse transcription PCR (RT-PCR) on throat swab samples. Forty five (59.2%) children <5 years and 31 (40.7%) children ≥5 years age group were positive for M. pneumoniae infection, and this difference was statistically significant (P ≤ 0.01).Clinical and radiological findings across M.pneumoniae-positive and -negative cases were comparable. Serology, PCR, nested PCR, and RT-PCR together detected M. pneumoniae infection in 76 (31%) patients. Sensitivity, specificity, and positive and negative predictive values of PCR were 16.18%, 95.48%, 57.89%, and 74.78%, respectively, and those of serology were 57.89%, 74.78%, 16.18%, and 95.48%, respectively. Serological and molecular detection in combination is useful for rapid and reliable diagnosis of M. pneumoniae infections in children with LRTIs., (Copyright © 2019 Elsevier Inc.

Background: Under the Revised National Tuberculosis Control Program (RNTCP) in India children are receiving antituberculosis treatment (ATT) as per a weight band system. In this children may be receiving antituberculosis drugs in doses which may be more or less than that recommended in mg/kg body weight doses. The recommended dose of isoniazid (INH) for intermittent therapy under the RNTCP is 8-12 mg/kg body weight and by the World Health Organization (WHO) for daily therapy is 10-15 mg/kg body weight., Aims: To evaluate the blood levels and pharmacokinetics of INH, in children suffering from tuberculosis, at doses administered under the weight band system of the Revised National Tuberculosis Control Program (RNTCP) 2009 of India., Design: Prospective, open label, non-randomized single-dose study conducted in 20 children in the age group 5-12 years attending the outpatient, chest clinic of a tertiary care hospital., Results: Group I (n = 8) included children who received INH in a dose of 10 mg/kg body weight or more and Group II (n = 12) included those who received INH in a dose less than 10 mg/kg body weight. The mean peak INH concentration (Cmax) was 6.03 ± 1.4 μg/mL and this was achieved in 2 hours (Tmax). The mean serum INH concentration was significantly higher in children who received INH in dose more than 10 mg/kg (Group I) as compared to those who received INH in doses lesser than 10 mg/kg body weight (Group II) at all-time points except at 2 hours (P < 0.05). The Cmax was also lower in Group II patients in comparison to Group I patients. Area under the concentration time curve (AUC) was significantly lower in Group II patients (P value 0.002). The elimination half-life of INH was 4.3 ± 0.4 h, elimination rate constant 0.16 ± 0.01/h, the volume of distribution 44.05 ± 5.3 L and clearance 7.1 ± 0.8 L/h., Conclusions: Lower blood levels and AUC of INH were achieved in children receiving doses of INH lesser than 10 mg/kg body weight. Long elimination half-life of INH is indicative of a slower rate of metabolism. Lower INH levels despite a slower rate of drug metabolism indicate caution with the INH doses being administered to children for intermittent therapy under the RNTCP., (Copyright © 2015 Tuberculosis Association of India.

Tracheobronchial injuries (TBI) are uncommon but potentially fatal injuries that can occur following blunt trauma to the thoracic region. Occasionally the diagnosis is not made at initial presentation, and patients present late with various sequelae. A 3 year old boy sustained blunt thoracic injury and developed respiratory distress, pneumothorax, and subcutaneous emphysema, which were managed conservatively with intercostal tube. Bronchoscopy performed to assess the cause of persistent collapse of the right lung and continued respiratory distress showed complete block of right main bronchus one cm away from the carina. Thoracotomy was performed and the transected ends of the bronchus were anastomosed. Postoperatively the right lung expanded with relief in respiratory distress. This report highlights the success of delayed repair of TBIs as an alternative to pneumonectomy., (Copyright © 2013 Elsevier Inc. All rights reserved.)

A national consultation was organised in January 2012, in order to reconcile between global and national guidelines, to review the evidence base and update the RNTCP guidelines in consensus with Indian Academy of Paediatrics. The consultation had come up with wider recommendations in diagnosing and treating paediatric tuberculosis patients which has been incorporated in the programme.

Severe malnutrition is known to affect the pharmacokinetics of isoniazid (INH) in children. However, the effect of moderate malnutrition, which may be more prevalent, is not known. INH was administered to 20 children with tuberculosis at a single dose of 5 mg/kg, and serial blood samples were collected. The serum INH concentrations were higher in the undernourished group but the pharmacokinetic parameters were comparable with those in the normal nutrition group. Weight gain was significantly more in the undernourished group after 1 month of treatment. The study suggests that INH pharmacokinetics may not be significantly altered in children with moderate malnutrition.

Steroids (corticosteroids) are anti-inflammatory drugs. Corticosteroids are used in many pulmonary conditions. Corticosteroids have a proven beneficial role in asthma, croup (Laryngotracheobronchitis), decreasing the risk and severity of respiratory distress syndrome (RDS), allergic bronchopulmonary aspergillosis, interstitial lung disease, hemangioma of trachea, Pulmonary eosinophillic disorders. Role of corticosteroids is controversial in many conditions e.g. idiopathic pulmonary hemosiderosis, bronchiolitis, hypersensitivity pneumonitis, hyperplasia of thymus, bronchiolitis, acute respiratory distress syndrome, aspiration syndromes, atypical pneumonias, laryngeal diphtheria, AIDS, SARS, sarcoidosis, meconium aspiration syndrome (MAS), pulmonary haemorrhage, bronchitis, bronchiolitis obliterans with organizing pneumonia in JRA, histiocytosis, alpha-1 antitrypsin deficiency, bordtella pertusis, pulmonary involvement in histiocytosis. However these are used empirically in many of these conditions despite lack of clear evidence in favour. There is concern about their side effects, especially on growth. Systemic steroids are associated with significant adverse effects. Pulmonary conditions have a strategic advantage that inhaled corticosteroids are useful in many of these. Although inhaled preparations of corticosteroids have been developed to maximise effective treatment of lung diseases characterised by inflammation and reduce the frequency of harmful effects, these have not been eliminated. There are situations where only systemic steroids are useful. Clinicians must weigh the benefits against the potential detrimental effects. It is recommended that standard protocols for use of steroids available in literature should be followed, always keeping a watch on the potential hazards of prolonged use.

Diagnosis of asthma is clinical, however due to varied presentations in childhood both under and over diagnosis are possible. A good number of cases may not present with wheeze but may have a cough variant asthma. Episodic symptoms of airflow obstruction and reversibility are two very important features of asthma. Many congenital (Cystic fibrosis) and acquired conditions (foreign body) may cause wheezing in childhood and should be ruled out clinically or by specific investigations. Spirometry and peak expiratory flow rates help in objective assessment and are good tools for monitoring chronic patients. Total IgE has no role in diagnosis. There is now emphasis on co-management of asthma and patient/parents should be trained to keep symptoms records and wherever possible peak flow records. They should also be taught proper interpretation of readings for stepping up therapy in case of worsening.

Objective: To compare the efficacy of a commercial spacer device versus an improvised spacer device in delivering aerosolized beta-2 agonist through metered dose inhaler in an acute exacerbation of bronchial asthma., Design: Randomized controlled trial., Setting: Urban tertiary care teaching hospital., Methods: 60 children between 1 to 12 years of age with acute asthma were prospectively enrolled and randomized into two groups. Detailed history, clinical evaluation and appropriate laboratory investigations were recorded on a pretested proforma. One group received inhaled salbutamol using metered dose inhaler via commercial spacer device (Group 1), while the other received it via improvised spacer device (Group II). The response was sequentially assessed after 20, 40 and 60 minutes of institution of therapy., Results: The two groups were comparable with respect to various parameters at presentation (p > 0.05). All the outcome parameters showed a significant improvement with time in both groups (p < 0.05). There was no statistical difference between the response in the two groups (p< 0.05)., Conclusion: Metered dose inhaler with improvised spacer device is equivalent in efficacy and a more cost effective alternative to metered dose inhaler with commercial spacer for administration of beta-2 agonist in acute asthma.

Sinus histiocytosis with massive lymphadenopathy (SHML) or Rosai-Dorfman disease is a rare but well-defined histiocytic proliferative disorder. There are only few reports or small series of cases on the fine-needle aspiration (FNA) cytologic features of this entity. Our first case was a 14-yr-old girl who presented with low-grade fever and neck swellings of 2 mo duration. FNA smears from the submandibular and cervical lymph nodes showed numerous histiocytes with evidence of lymphophagocytosis (emperipolesis) against a background of reactive lymphoid cells. The FNA cytodiagnosis was Rosai-Dorfman disease. The patient was put on steroids, with improvement. The second patient was a 3(1/2)-yr-old girl who presented with fever and left cervical lymphadenopathy. The initial FNA smear from an outside laboratory was reported as reactive hyperplasia. A repeat FNA smear showed numerous histiocytes with evidence of emperipolesis, mild nuclear enlargement and multilobation/multinucleation in a few histiocytes, and reactive lymphoid cells. The cytodiagnosis was Rosai-Dorfman disease. Review of the initial smear showed the Rosai-Dorfman (RD) cells, but in smaller number. We conclude that FNA cytology is a useful tool in the diagnosis of SHML, but the diagnosis may be missed at initial stages when characteristic cytomorphologic features are not well-developed.
