Due to the expansion of human population, threat for existence of all wild animals is gradually increasing. They are driven to exist in smaller areas and in the worst case scenario extinction. Zoos are being encouraged to improve the animal’s physical and social surroundings. In this study, the modern naturalistic enrichment introduced to large felids tiger, lion and leopard at Gandhi Zoological Park, Gwalior, Madhya Pradesh, was studied. The study has envisaged evaluating if the modern naturalistic enclosures could increase activity levels and how the felids opted to these enclosure. The enclosures were divided into menageries and natural enrichment, which had a varying degree of opportunities for the animals to climb, hide and rest above ground level. The environmental enrichment effects on the proportion of time spent engaging in active behaviors and stereotypic pacing in the large felids were compared and recorded using instantaneous scan sampling. The results of this study revealed clearly that large felids kept in more natural and complex enclosures performed less stereotypic pacing (unnatural behavior), and more exploratory (natural) behaviour than those housed in less natural enclosures reducing the stress level in captive tigers will enhance the animals’ overall physical and psychological well being, which will in turn increase the success of captive breeding programs. Furthermore, these results suggest that captive tigers should be housed in large enclosures containing natural substrate and vegetation, water pools, ample shade, a variety of resting locations and enrichment items

This study was undertaken to study the occurrence of cholera in young children with a view to define the clinical criteria of diagnosis and endemicity of cholera in Delhi and to compare its clinical profile with rotavirus diarrhea. Hundred children below 3 years of age admitted with acute watery diarrhea were recruited. The severity of diarrhea and degree of dehydration were noted. Stool specimens collected from all cases were subjected to bacterial culture for identification of Vibrio cholerae and rotavirus detection by ELISA and PAGE techniques. Both Vibrio cholerae and rotavirus were detected in 5, Vibrio cholerae alone in 13 and rotavirus alone in 18 cases. Sixty-one percent cases of cholera occurred in children below two years. Rice watery stools were seen only in 28% (5/18) cases of cholera. Three (3/13) cases with cholera alone and 6/18 with rotavirus alone had mild diarrhea. Moderate diarrhea occurred in 3/5 cases with both pathogens, 6/13 with cholera alone and 7/18 with rotavirus alone. Severe diarrhea occurred in 3/5 cases with both pathogens, 4/13 with cholera alone, and 5/18 cases with rotavirus alone. Mild dehydration occurred in 3/5 and severe dehydration in 2/5 children with both pathogens. Only 3/13 children with cholera alone and one child with rotavirus alone were severely dehydrated. It is concluded that considering the diagnosis of cholera solely on clinical grounds and overlap between the clinical spectrum of cholera and rotavirus diarrhea would result in missing many cholera cases in a non-endemic area like Delhi.

Despite remarkable decline in the number of poliomyelitis cases, the dream of polio eradication in India remains elusive. This is despite considerable effort and expenditure for well over a decade. Various reasons have been cited for this and interventions implemented accordingly. None of these seem to have borne fruit. It is appropriate to have a relook at the polio eradication strategies in order to learn from past errors and determine a feasible solution to achieve the goal. This article examines important tissues that hamper the eradication effort and proposes a way forward.

OBJECTIVE: This study was carried out to determine the prevalence of HIV infection in North India, as there are scanty reports from this part of India. METHODS: The prevalence of HIV infection was determined by serological tests for HIV antibodies in children born to a seropositive mother or suffering from chronic diarrhea, failure to thrive or disseminated tuberculosis. RESULTS: One hundred and twelve children were tested of which ten were seropositive (8.9%). This included six children born to seropositive mother (22%), two with chronic diarrhea (4%), one with failure to thrive (5%) and one child with disseminated tuberculosis (6.6%). CONCLUSION: HIV infection is an emerging reality in New Delhi. A clinically directed screening can help detect more cases.

OBJECTIVE: This study was carried out to evaluate the adequacy of seroconversion when Hepatitis B vaccine is given along with other vaccines at 0, 6 weeks (along with DPT and OPV) and at 9 months (along with measles). METHODS: 725 infants born to apparently healthy mothers were enrolled to receive the hepatitis B vaccine at 0, 6 weeks and 9 months (Group A) or at 0, 1 and 6 months as per WHO schedule--(Group B). Baseline HbsAg testing was carried out and the babies were immunized with the first dose of hepatitis B vaccine within 48 hours of birth. BCG and the other EPI vaccines were given as per schedule. Serum samples were collected 4 weeks after the second and the third immunizations. 604 infants (83.3%) completed the study. The testing for HbsAg and Anti Hbs titers were conducted in the Department of Microbiology, Maulana Azad Medical College, New Delhi utilizing standard ELISA kits. RESULTS: The seroconversion rates 4 weeks after the second dose of the vaccine were 90.89% (GMT = 48.23) and 91.82% (GMT = 43.95) (P=0.8) in Group A and Group B respectively. After 4 weeks of the third dose the seroconversion rates were 98.99 (GMT = 161.12) and 98.45 (GMT = 150.12) (p=0.17) in Group A and Group B respectively. The two schedules were comparable on using the Kruskal-Wallis H method for analysis. CONCLUSION: The schedule of hepatitis B vaccination at 0, 6 weeks and 9 months has the same seroefficacy as the currently recommended schedule of 0, 1 and 6 months.

OBJECTIVE: To study the occurrence of nosocomial diarrhea in pediatric wards and the role of infections in its causation. METHODS: 75 cases conforming to the CDC definition of nosocomial diarrhea were selected for the study. Stool samples were subjected to direct microscopic examination, bacteriological culture and direct antigen detection for Clostridium difficile (C. difficile) and Rota virus. RESULTS: All the cases were sporadic in origin. Rota virus was detected in 16.67% cases and Enteropathogenic Escherichia coli (E.P.E.C.) was detected in 12% cases. Cases in which no pathogen was detected (82.7%) outnumbered those in which a pathogen was identified (17.3%). CONCLUSION: Rota virus and E.P.E.C were the most common etiological agents. C. difficile was detected in one case only. Most of the sporadic cases of nosocomial diarrhea in pediatric patients can be managed on fluids and electrolytes.

OBJECTIVE: The study was undertaken with the aim to determine correlation between the initial plasma cortisol level and severity of asthma attack and the response to standard treatment for acute exacerbation of bronchial asthma in pediatric age group. METHODS: The study was performed in 33 asthmatic patients between 5-12 years of age, presenting to pediatric emergency with acute exacerbation of bronchial asthma. None of the patients included in the present study was on steroids. Venous blood sample for determination of plasma cortisol level was taken and patients were nebulized with salbutamol every 20 minutes, up to 1 hour. The patients who failed to respond even after three nebulizations were labeled as nonresponders and repeat venous blood sample for plasma cortisol estimation was taken before giving injection hydrocortisone. In responders sample was taken 1 hour after last nebulization. RESULTS: The mean plasma cortisol value at the time of admission in responders (12.42 +/- 1.9 microg/dl) was not found to be significantly different from that in nonresponders (13.1 +/- 2.74 microg/dl). Children with severe attack of asthma had significantly higher plasma cortisol levels both at the time of admission (p=0.03) and at the end of study (p=0.001), as compared to patients with moderate attack. The mean percentage change in plasma cortisol levels in nonresponders was an increase of 80.65 +/- 60.64%, whereas, in responders it decreased by 16.49 +/- 21.7% and this difference was statistically significant (p<0.05). CONCLUSION: The hypothalamo pituitary adrenal axis functions normally in asthmatic patients, producing a rise in cortisol levels corresponding to degree of stress; and from initial cortisol level alone, it cannot be predicted, whether a patient will respond to beta-2 agonist (salbutamol) nebulization alone or will require exogenous corticosteroids.

Vaccine Associated Paralytic Poliomyelitis (VAPP), although a known hazard with Oral Polio Vaccine (OPV), has not received adequate attention in India despite increasing use of OPV in repeated rounds of national immunization days. An analysis by National Polio Surveillance Project in 1999 suggested that incidence of VAPP is lower in India compared to that in the developed countries. However a re-analysis of the NPSP data suggests that the incidence in India is likely to be 1 in 1.5-2.0 million doses, which is higher than that reported elsewhere. Since 1999, the number of AFP cases in which the vaccine virus has been isolated, has progressively gone down, despite increasing number of OPV doses being administered in the national program. This contradictory phenomenon is difficult to explain unless either the doses being actually given are much less than those recorded or the vaccine being given is not potent. It is essential that the problem of VAPP is looked at in depth, and if it reveals that it is a significant problem then it would be imperative to gradually replace OPV by IPV in the national program. This article suggests a plan for gradual introduction of IPV in the national program, which will not only eliminate the problem of VAPP but also address other post polio eradication concerns.

H pylori infection is highly prevalent in asymptomatic children and it varies between countries and often within a country as well. Initial infection probably occurs at an early age and prevalence increases with age. Ethnic and racial factors, socio-economic status and living conditions affect the prevalence of infection. Long term population based studies are needed to identify the exact prevalence and clinical significance in Indian children. There is strong evidence for an association between H pylori infection and antral gastritis and duodenal ulcer disease in children, but it's association with recurrent abdominal pain needs further evaluation. Diagnostic tests for H pylori are based either on direct demonstration of the organism or indirectly by detecting a by-product (of the urease reaction) or by demonstrating antibodies. Histopathological identification of H pylori in [table: see text] antral biopsy specimen is by far the best method and is currently regarded as gold standard. Serological tests detecting IgG and IgA are possible tools for diagnosis but have many drawbacks. They may be useful for population surveys where invasive tests are not feasible. These tests should be standardized for the population for which they are going to be used. Urea breath test is a highly sensitive non-invasive test for H pylori infection and can be used even in a field setting. Urea Breath test needs to be standardized in tropical countries with high rates of dental colonization and duodenal microbial contamination. Newer diagnostic tests for H pylori infection are emerging but most have not been validated in various populations. Routine testing for H pylori is not indicated in children or adults. The decision to perform a diagnostic test has often to be linked with a therapeutic proposal. The only condition for which H pylori treatment is indicated is duodenal ulcer which is very uncommon in children. Treatment for RAP or even dyspepsia is not warranted on clinical grounds. There are several treatment regimens available, but it appears that at least three drugs including two antibiotics and a proton pump inhibitor are required for satisfactory eradication. In developing countries where the prevalence of infection is very high, well-planned double blind cross-over studies are needed before an evidence based answer can be provided for an optimal therapeutic strategy.

Hepatitis B has attracted a lot of attention in recent times. It has been suggested that it is a widely prevalent disease and an important cause of morbidity and mortality in our country. A dispassionate analysis of available data suggests that the prevalence of disease may be much less than believed hitherto, and the morbidity and mortality due to the disease may have been overestimated. Vertical transmission from mother to child at the time of delivery may be an important contributor to overall carrier rates in the community which warrants that the first dose of vaccine be administered within 24-48 hours of birth to all newborns. In view of this, the suggestion that Hepatitis B vaccine be incorporated in the National UIP also has many logistical difficulties, apart from a doubtful cost benefit ratio. This may therefore be not warranted at present. Also it would appear that the routine use of Hepatitis B vaccine in older individuals cannot be justified on epidemiological grounds in India and the widespread practice of holding camps for administering Hepatitis B vaccine to school children and other older citizens need to be re-examined.

OBJECTIVE: To evaluate protien using enteropathy by Tc-99m dextran scintigraphy. METHODS: Methods for detecting protein loss from the intestine revolve around fecal nitrogen excretion, the clearance of alpha-1 antitrypsin in stools and by endoscopic biopsy. RESULT: The diagnosis of protein-losing enteropathy (PLE) can also be established by a scintigraphic method that is noninvasive, simple and requires no patient preparation or motivation. This diagnostic modality can also delineate the site of protein loss, thereby offering a targeted approach, and if need be, surgery. Radiolabelling of a non-protein, noncolloidal, nonparticulate and biofriendly molecule like dextran with Technetium-99m for imaging enteric protein loss was utilized in imaging eight children with PLE. CONCLUSION: The results were encouraging. The authors advocate the use of this diagnostic tool in identifying patients with PLE, particularly in the pediatric age group.

OBJECTIVES: To assess the prevalence of gastrooesophageal reflux disease (GERD) as suggested by the symptom profile in babies ranging in age from 1 month to 2 years. METHODS: Six hundred and two babies were recruited from the well baby clinic for hospital delivered babies and from the childrens OPD of a tertiary care hospital. Children with acute severe illness needing hospitalization were excluded from the study. The primary care taker of each baby was interviewed using a questionnaire (IGERQ) designed by Orenstein et al and the I-GERD score obtained was used to assess for likelyhood of GERD. Upper gastrointestinal (GI) endoscopy was carried out and an oesophageal biopsy was taken in clinically suspected cases of GERD (IGERD > 5). RESULTS: Sixty one (10%) of the 602 subjects had an I-GERD score of > 5 suggestive of GERD. Regurgitation was present in 56 of these 61 subjects and also in 106 of the 541 normal subjects. 112 of 205 infants aged 1-6 months had regurgitation and 25 (22.2%) of these regurgitant infants had a score suggestive of GERD. Only 30 of the 202 infants aged 6-12 months and 20 of the 195 babies aged 12-24 months had regurgitation, however 14 of the 30 (46.5%) and 17 of the 20 (85%) regurgitant babies had an I-GERD score suggestive of GERD. Upper GI endoscopy was carried out in 31 babies with a score > 5 and endoscopic oesophagitis was detected in 16 (51.6%). Oesophageal biopsies were taken in 25 of these cases and showed histological evidence of reflux oesophagitis in 23 (92%). CONCLUSION: GERD is fairly common under 2 years of age as observed by symptom evaluation using the I-GERD score. Regurgitation when present beyond 6 months of age with no other identifiable cause needs evaluation. Upper GI endoscopy and oesophageal biopsy is a useful means of demonstrating reflux oesophagitis in babies with a symptom profile suggestive of GERD.
