RESUMO
14 cases of neural tube defect (NTD) were detected on screening of 1950 pregnant women over a period of 30 months by antenatal ultrasonography (USG) examination, suggesting an incidence of 7.1 per thousand conceptions. The distribution of types of NTD were occult dysraphism 14%, meningocele 14%, myelocele 7%, myelomeningocele 14%, encephalocele 14% and anencephaly 37%. The study established high accuracy of USG screening for antenatal diagnosis of NTD with sensitivity of 85.71% and specificity of 100.
RESUMO
Adverse event following immunization (AEFI) is a critical component of immunization program. The risk of AEFI with vaccination is always weighed against the risk of not immunizing a child. There is an evolving AEFI surveillance system in India for the vaccines delivered through universal immunization program (UIP) of government sector, but the reporting remained suboptimal for long in the country, and there is almost no participation from private sector. The AEFI reporting from private sector will provide vital information on the safety of new and underutilized vaccines, not part of the UIP in India. The national guidelines are recently revised and updated. The Indian Academy of Pediatrics believes that pediatricians, especially in private sector have a crucial role to play with reporting of AEFI with newer/underutilized vaccines. Programmatic error, vaccine reaction, injection reactions, coincidental and unknown are the five broad categories of AEFI for programmatic purposes. The serious AEFIs (death, disability, cluster and hospitalization) need to be reported immediately and investigated in detail as per the laid down procedures. Once a serious AEFI happens, primary or urban health centre should be immediately informed by the pediatricians practicing in rural or urban areas, respectively. This advocacy paper from the academy provides guidelines to practitioners on how to report cases, and suggests ways for IAP members to help in ongoing efforts of the government in improving AEFI surveillance in the country. The details about the diagnosis and management of known/expected AEFI with UIP and newer vaccines shall be published later.

Measles continues to be a major cause of childhood morbidity and mortality in India. Recent studies estimate that 80,000 Indian children die each year due to measles and its complications, amounting to 4% of under-5 deaths. Immunization against measles directly contributes to the reduction of under five child mortality and hence to the achievement of Millennium Development Goal 4 (MDG 4). The live attenuated measles vaccines are safe, effective and provide long lasting protection. The key strategies being followed globally for measles mortality reduction are high coverage of measles first dose, sensitive laboratory supported surveillance, appropriate case management, and providing second dose of measles vaccine. Prior to 2010, India was the only country in the world that had not introduced a second dose of measles vaccine in its National immunization program. We herein discuss the current status of measles vaccination along with the rationale and challenges of providing a second opportunity for measles vaccination, and the principles of measles catch-up campaigns.

Cultures of Thiobacillus ferrooxidans and Thiobacillus thiooxidans, used in biohydrometallurgical processes of economic importance, are very difficult to preserve by conventional methods. Hence, to preserve the cultures with their activity intact, various techniques were tried, after determining their respective activity in terms of Iron Oxidation Rate (IOR) and Sulfur Oxidation Rate (SOR). Among the methods tested, along with the recommended method of serial transfer in a liquid medium, were methods such as lyophilization, storage in a liquid nitrogen and mixing with sterile, inert carriers like lignite or chalcopyrite ores. After a period check-up at 4 months and 8 months storage, it was found that out of these methods, mixing with sterile ore followed by storage at 8 degrees C, kept both types of activities intact. The temperature of storage was observed to have a definite effect on activity, in that when the preserved cultures were stored at 8 degrees C, the activity was retained, whereas at 28-30 degrees C (RT) storage, the activity of all the cultures preserved by various techniques, dropped significantly.

BACKGROUND: Pancreatic tuberculosis is a rare disease. Its presenting features are usually vague and non-specific, while the radiological features mimic pancreatic malignancy in many cases and pancreatitis in others. Ultrasound- or CT-guided fine-needle aspiration cytology (FNAC) or biopsy may show caseating granulomatous inflammation but microbiological confirmation may not always be possible. Laparotomy may be required if other investigations prove inconclusive. The response to treatment is good. CASE OUTLINES: We report two young men with pancreatic tuberculosis. The diagnosis was obtained by FNAC in one and laparotomy in the other. Each patient responded to anti-tuberculous chemotherapy and is now asymptomatic. CONCLUSION: Tuberculosis should be considered in the differential diagnosis of an obscure pancreatic mass, and the condition is readily curable.
