Variations in Placental Attachment of Umbilical Cord.

Background: Our study aims to evaluate the variations in umbilical cord attachment to placenta by dissection method. Methods: Placentas for this study were obtained from the OBG Department and collected by the Department of Anatomy SRMS IMS. The placentas were washed, cleared, dissected and site of placental attachment to umbilical cord were observed. Variations in the type of insertion were noted. Result: Majority of the placentas showed central and eccentric attachments of the cord. Few abnormal placentas were observed with velamentous and marginal insertions of the umbilical cord. Conclusion: Abnormalities in the placental attachment of the umbilical cord can result in various complications of pregnancy and adversely affect the fetal outcome as well. Knowledge of the variations in attachment of the umbilical cord is very significant and of extensive use to obstetricians as well as anatomists. Frequently abnormal cord insertions may be associated with intrauterine growth retardation, preterm labour and congenital abnormalities.

Characterization of nasopharyngeal isolates of type b Haemophilus influenzae from Delhi.

Background & objectives: Haemophilus influenzae is an important cause of mortality and morbidity among young children in developing countries. Increasing incidence of antibiotic resistance especially production of extended spectrum beta lactamase (ESBL) has made treatment and management of H. influenzae infection more difficult. Nasopharyngeal H. influenzae isolates are excellent surrogate for determination of antibiotic resistance prevalent among invasive H. influenzae isolates. In this study, we characterized nasopharyngeal H. influenzae isolates obtained from healthy school going children in Delhi. Methods: Nasopharyngeal H. influenzae isolates were collected from healthy school going children and subjected to serotyping, fimbrial typing and antibiogram profiling. ESBL production was recorded using phenotypic as well as molecular methods. Multi locus sequence typing (MLST) of 13 representative nasopharyngeal H. influenzae isolates was performed as per guidelines. Results: A significant proportion (26 of 80, 32.5%) of nasopharyngeal isolates of H. influenzae were identified as serotype b. Fimbrial gene (hifA) was detected in 23 (28.75%) isolates. Resistance against commonly prescribed antibiotics (Amp, Tet, Chloro, Septran, Cephalexin) were observed to be high among the nasopharyngeal commensal H. influenzae. Extended spectrum beta lactamase (ESBL) production was observed in a five (6.25%) isolates by both double disk diffusion and molecular typing. MLST identified several novel alleles as well as novel sequence types. Interpretation & conclusions: Our findings showed high resistance against common antibiotics and detection of ESBL in nasopharyngeal H. influenzae isolates collected from normal healthy school going children in Delhi. Detection of H. influenzae type b capsular gene and the presence of fimbrial gene (hif A) suggest virulence potential of these isolates. Discovery of novel alleles and presence of new sequence types (STs) among nasopharyngeal H. influenzae isolates may suggest wider genetic diversity.

Is there need for a transformational change to overcome the current problems with postgraduate medical education in India.

In spite of the existence of a dual system of postgraduation, one under the Medical Council of India (MCI) and the other on a parallel track under the National Board of Examinations, postgraduate medical education in India is beset with several problems. For example, the curriculum has not been revised comprehensively for several decades. The diploma course under the MCI has become unpopular and is largely a temporary refuge for those who do not get admission to degree courses. The level of skills of the outgoing graduate is falling and the increase in the number of seats is taking place in a haphazard manner, without reference to the needs. In spite of increase in seats, there is a shortage of specialists at the secondary and tertiary care levels, especially in medical colleges, to share teaching responsibilities. Further, the distribution of specialists is skewed, with some states having far more than others. To remedy these ills and fulfil the requirements of the country over the next two decades, a working group appointed by the erstwhile governors of the MCI was asked to suggest suitable modifications to the existing postgraduate system. After an extensive review of the lacunae in the present system, the needs at various levels and the pattern of postgraduate education in other countries, it was felt that a competency-based model of a 2-year postgraduate course across all specialties, the use of offsite facilities for training and a criterion-based evaluation system entailing continuous monitoring would go a long way to correct some of the deficiencies of the existing system. The details of the proposal and its merits are outlined for wider discussion and to serve as a feedback to the regulatory agencies engaged in the task of improving the medical education system in India. We feel that the adoption of the proposed system would go a long way in improving career options, increasing the availability of teachers and dissemination of specialists to the secondary and primary levels, and improving the quality of outgoing postgraduates.

Determinants of utilization of services under MMJSSA scheme in Jharkhand 'Client Perspective': A qualitative study in a low performing state of India.

Preventing maternal death associated with pregnancy and child birth is one of the greatest challenges for India. Approximately 55,000 women die in India due to pregnancy- and childbirth- related conditions each year. Increasing the coverage of maternal and newborn interventions is essential if Millennium Development Goals (MDG) 4 and 5 are to be reached. With a view to accelerate the reduction in maternal and neonatal mortality through institutional deliveries, Government of India initiated a scheme in 2005 called Janani Suraksha Yojna (JSY) under its National Rural Health Mission (NRHM). In Jharkhand the scheme is called the Mukhya Mantri Janani Shishu Swasthya Abhiyan (MMJSSA). This paper focuses on community perspectives, for indentifying key areas that require improvement for proper implementation of the MMJSSA in Jharkhand. Qualitative research method was used to collect data through in-depth interviews (IDIs) and focus group discussions (FGDs) in six districts of Jharkhand- Gumla, West Singhbhum, Koderma, Deoghar, Garhwa, and Ranchi. Total 300 IDIs (24 IDIs each from mother given birth at home and institution respectively; two IDIs each with members of Village Health and Sanitation Committees (VHSC) / Rogi Kalyan Samitis (RKS) from each district) and 24 FGDs (four FGDs were conducted from pools of husbands, mothers-in-law and fathers-in-law in each district) were conducted. Although people indicated willingness for institutional deliveries (generally perceived to be safe deliveries), several barriers emerged as critical obstacles. These included poor infrastructure, lack of quality of care, difficulties while availing incentives, corruption in disbursement of incentives, behavior of the healthcare personnel and lack of information about MMJSSA. Poor (and expensive) transport facilities and difficult terrain made geographical access difficult. The level of utilization of maternal healthcare among women in Jharkhand is low. There was an overwhelming demand for energizing sub-centers (including for deliveries) in order to increase access to maternal and child health services. Having second ANMs will go a long way in achieving this end. The MMJSSA scheme will thus have to re-invent itself within the overall framework of the NRHM.

Multi locus sequence type comparison of invasive and commensal Haemophilus influenzae isolates from Delhi.

Haemophilus influenzae is a major public health concern in the developing world. The most virulent strain is H. influenzae Type b (Hib). Hib also constitutes a major portion of nasopharyngeal commensal flora in otherwise healthy individuals. Through dendogram based on composite gene sequences of seven multi locus sequence type genes, it was observed that invasive and commensal isolates made two completely separate clusters which are indicative of independent evolution of these two groups of H. influenzae in the Indian subcontinent.

Epidemiological transition of hepatitis A in India: issues for vaccination in developing countries.

With improvement in economic and living conditions of the communities, the age of acquiring hepatitis A virus (HAV) infection is shifting from early childhood to adolescence and young adulthood. Such epidemiological shift leads to an increased incidence of symptomatic HAV infection, including heightened risk of liver failure. Data from India indicate that the population is no longer homogeneous for its HAV exposure profile. Occasional outbreaks of HAV and higher proportions of symptomatic cases are reported amongst older children and adults from different regions of the country. However, the heterogeneous exposure to HAV defies widespread use of the vaccine. The challenge is to recognize the susceptible pockets and take pre-emptive steps. In regions with rapid improvement in living standards and environmental hygiene, there is a need for regular surveillance through structured protocols that are able to identify early signs of epidemiological shift. This review discusses relevant issues and concerns to influence decision making for HAV vaccination in such transition societies.

Social determinants and polio 'endgame': a qualitative study in high risk districts of India.

OBJECTIVES: To understand the perceptions and likely determinants that facilitate or act as barriers in implementing additional strategies for polio eradication: (a) accelerated delivery of mOPV1 (monovalent polio vaccine type 1); (b) use of IPV (inactivated polio vaccine); and (c) provision of incentives. DESIGN: QUALITATIVE. Rapid appraisal procedures (RAP) were adopted to derive the reality by synthesizing multiple sources of information; search for opinions, motivations, behaviors and attitudes of key stakeholders within their organizational and socio-cultural matrix. SETTING: Two districts of Uttar Pradesh - Moradabad and J P Nagar. SUBJECTS: Total 244 interactions were conducted; 33 interviews and 4 focussed group discussions (FGD) conducted with providers; 33 mothers (<5 years) and 10 leaders were interviewed; 8 FGD were conducted with mothers of under-fives. Informal interactions (156) were also conducted with village pradhans, religious leaders, parents, businessmen, journalists (Hindi and Urdu media), mobilizers, vaccinators and supervisors. RESULTS: Providers expressed reservation regarding accelerated rounds of OPV; scientific rationale of accelerated rounds is not clear to parents and leaders. Although technical advantages of introducing IPV exist, issues of logistical difficulties and injection safety emerged strongly. Providers and communities indicated a clear 'no' to the cash incentives but argued for developmental issues. Resistance to the program has declined over time but still the program is perceived as the "government's need, not ours". CONCLUSION: The polio eradication program is critically poised, an opportunity to intensify efforts for reducing inequities in health services and improve access of all children to the PHC services. Ongoing dialogue with local communities and strong political commitment would be essential to translate the technological innovations into a sustainable program.

Alpha-1 antitrypsin deficiency among Indian children with liver disorders.

AIMS: To determine the frequency of alpha-1 antitrypsin (AAT) deficiency in children with chronic liver disease (CLD) and neonatal cholestasis syndrome (NCS). METHODS: All children with NCS (n=23) or CLD (n=35) attending the Pediatric Gastroenterology Clinic between November 2003 and July 2005 were screened for AAT deficiency using phenotyping through isoelectric focusing of plasma. RESULTS: Of the 58 children studied, 57 had normal PiMM phenotype. One child with CLD had the M1E type of normal variant. None of the patients had the abnormal phenotype PiZZ. CONCLUSION: AAT deficiency is infrequent among children with CLD and NCS in our region.

Pancreatic diseases in children in a north Indian referral hospital.

This was a cross-sectional study to determine the profile of pancreatic disorders in 54 children (age <15 years) presenting to a tertiary care center in India. Acute pancreatitis was the most common pancreatic disorder (28/54, 52%). Twenty-three children (43%) were diagnosed to have either chronic calcific (n = 15, 28%) or chronic non-calcific (n = 8, 15%) pancreatitis. Specific etiologic factors could be identified in 64.3% (18/28) of acute pancreatitis and 43.5% (10/23) of chronic pancreatitis patients. At least some of the 13 children with idiopathic chronic pancreatitis had features suggestive of tropical pancreatitis.

Streptococcus pyogenes meningitis.

Group A Streptococcus (GAS) is a rare cause of meningitis. Although it has a high mortality, the condition is easily treatable if diagnosed early since the bacteria retains its sensitivity to many antimicrobials. The authors report here two cases of GAS meningitis along with a review of world literature.

Acute liver failure.

Acute liver failure in children is associated with a high mortality. Most cases in our setup are due to water borne hepatotropic viruses HAV and HEV. The clinician must be aware of the earliest and the subtle signs of acute liver failure to identify cases early enough and institute supportive therapy. Focus of therapy has to be on prevention, early recognition and appropriate management of complications. Despite good intensive care, about 40-60% children with liver failure die. As and when liver transplantation becomes available in India, it would be an attractive option.

Nasopharyngeal carriage of Haemophilus influenzae.

OBJECTIVE: Nasopharyngeal colonization of Haemophilus influenzae (H. influenzae) in young children may be important in developing countries. METHOD: In this study, we screened school going children for carriage of H. influenzae. A total of 44 H. influenzae isolates out of a collection of 162 were characterized for biotypes, capsular serotypes and antibiotic resistance. RESULTS: A significant proportion of H. influenzae (25/44) isolates were serotype b. High antibiotic resistance was observed against commonly administered antibiotics like ampicillin (79%), chloramphenicol (20%), trimethoprim sulfamethoxazole (84%) and erythromycin (95%). Comparison of antibiotic resistance profile of nasopharyngeal isolates was observed to be correlated with those of H. influenzae from disease. CONCLUSION: Multidrug resistant nasopharyngeal H. influenzae in young healthy children may act as reservoir. Monitoring of antibiotic resistance among nasopharyngeal H. influenzae as a surrogate for invasive H. influenzae seems an attractive option.

Upper gastrointestinal bleeding: etiology and management.

Upper gastrointestinal bleeding is a potentially fatal condition at times due to loss of large volumes of blood. Common sources of upper gastrointestinal bleeding in children include mucosal lesions and variceal hemorrhage (most commonly extra hepatic portal venous obstruction) and, in intensive care settings infections and drugs are other etiological factors associated with bleeding. Massive upper GI bleeding is life threatening and requires immediate resuscitation measures in the form of protection of the airways, oxygen administration, immediate volume replacement with ringer lactate or normal saline, transfusion of whole blood or packed cells and also monitoring the adequacy of volume replacement by central venous lines and urine output. Upper GI endoscopy is an effective initial diagnostic modality to localize the site and cause of bleeding in almost 85-90% of patients. Antacids supplemented by H2- receptor antagonists, proton pump inhibitors and sucralfate are the mainstay in the treatment of bleeding from mucosal lesion. For variceal bleeds, emergency endoscopy is the treatment of choice after initial haemodynamic stabilization of patient. If facilities for endoscopic sclerotherapy (EST) are not available, pharmacotherapy which decreases the portal pressure is almost equally effective and should be resorted to. Shunt surgery is reserved for patients who do not respond to the above therapy. Beta blockers combined with sclerotherapy have been shown to be the most effective therapy in significantly reducing the risk of recurrent rebleeding from varices as well as the death rates, as compared to any other modality of treatment. Based on studies among adult patients, presence of shock, co-morbidities, underlying diagnosis, presence of stigmata of recent hemorrhage on endoscopy and rebleeding are independent risk factors for mortality due to upper GI bleeding. Rebleeding is more likely to occur if the patient has hematemesis, liver disease, coagulopathy, hypotension and or anemia. There is a great need for conducting therapeutic trials as well as identifying predictors of outcome of upper GI bleeding in children to develop evidence based management protocols.

Sero-epidemiology of hepatitis E virus (HEV) in urban and rural children of North India.

OBJECTIVE: To estimate the prevalence of anti-HEV IgG and IgM antibodies to ORF3 peptide of Hepatitis E virus genome in an age stratified urban and rural population of children. DESIGN: Cross sectional survey. SETTING: Pediatric out-patient clinics in a tertiary hospital and a rural dispensary. METHODS: Study subjects between 6 months and 10 years with minor, non-hepatic illnesses were recruited for the study from March to December 1996. Baseline demographic details, drinking water source, sewage disposal methods, reasons for attending the hospital, histories of parenteral exposure in the past 12 months and acute hepatitis in the subjects and the family in the previous six months were obtained. Serum anti-HEV IgG antibodies were screened in all subjects, and in those who were positive, anti-HEV IgM antibodies were assayed as an indicator of recent infection. Serum aminotransferase (ALT) was estimated in those who were anti-HEV IgM antibody positive. RESULT: Out of 2160 subjects recruited, 2070 samples could be screened for anti-HEV IgG antibodies. In the urban population (n = 1065) anti-HEV IgG antibodies were detected in 306 subjects (28.7%; 95% CI 26.0-31.6) and of these 131 (42.8%; 95%CI 37.2-48.6) were anti-HEV IgM antibody positive. Amongst 1005 rural children, anti-HEV IgG antibodies were present in 239 (23.8%; 95% CI 21.1-26.4) and IgM antibodies in 113 (47.3%; 95% CI 40.9-53.7) children. The antibodies were present since the first year of age till 10 years of age and, increased with advancing age. Serum transaminases were raised in 7.5% (9/120) and 5.5% (5/88) of subjects with anti-HEV IgM antibodies in urban and rural centers respectively. Overall the seroprevalence of IgG antibodies against HEV were significantly more in urban as compared to that in rural subjects (p = 0.011). However, proportion of children with anti-HEV IgG carrying IgM antibodies was similar in the two study groups (p = 0.298). A model for estimating expected prevalence of anti-HEV IgG antibodies was developed. The observed antibody prevalence in both urban and rural subjects at each age interval after 48 months was less as compared to the expected levels and this gap increased with advancing age categories. It appeared that there was a decay of HEV antibodies with time. CONCLUSIONS: Children are susceptible to HEV infection since early infancy. The probability of exposure to HEV during childhood was higher in urban than rural population. Seropositivity to HEV antibodies increased by over 2 times beyond 4 years of age as compared to younger age. Anti-HEV IgG antibodies appear to wean off with increasing age.

Quantitative vs qualitative research methods.

Quantitative methods have been widely used because of the fact that things that can be measured or counted gain scientific credibility over the unmeasurable. But the extent of biological abnormality, severity, consequences and the impact of illness cannot be satisfactorily captured and answered by the quantitative research alone. In such situations qualitative methods take a holistic perspective preserving the complexities of human behavior by addressing the "why" and "how" questions. In this paper an attempt has been made to highlight the strengths and weaknesses of both the methods and also that a balanced mix of both qualitative as well as quantitative methods yield the most valid and reliable results.

Randomized controlled trial and economic evaluation.

Conducting economic evaluation alongside clinical trials is an efficient way of getting valid and reliable information with minimum assumptions made during data collection. However, design of a randomised control trial (RCT) takes away several of the real world situations, the variations in resource utilisation, their cost due to close supervision and monitoring of the study subjects. Suitable sensitivity analysis has to be done to make the economic data obtained more pragmatic and hence utilised by the policy makers.

Focus group discussions in medical research.

Qualitative research methods have recently started to gain popularity in social and health sciences for determining a more holistic view of peoples' perceptions about health. Focus group discussions are frequently used to obtain perspectives and attitudes of people about issues, seek explanations for behavior, triangulate data obtained through other qualitative methods and generate hypotheses. To facilitate clinicians to comprehend the use of focus group methodology in the clinical field, the meaning, purpose, advantages, limitations and quality assurance measures of focus group discussions are described. The general requirements and the method for conducting focus groups are briefly explained. In addition, key issues that could be addressed by focus group methodology have also been highlighted.
