Vitamin B12 Status in Rural Adolescent School Girls in Mysuru, India: A Community-Based Cross-Sectional Study.

Almost 56% of Indian adolescent girls aged 15-19 years suffer from anemia. Adolescent age is a period of many significant physiological changes that increase nutritional demand, and they remain at risk for nutritional deficiencies. Our aim is to assess the prevalence of Vitamin B12 deficiency among school-going adolescent girls aged 13-16 years of rural Mysore. This study was a cross-sectional study, conducted in two high schools in rural Mysuru. Adolescent girls aged 13-16 years were included. The chosen subjects underwent complete hemogram, peripheral smear examination, and vitamin B12 level estimation. Out of 98 subjects enrolled, 40.81% were found to be deficient in vitamin B12. Macrocytes and hyper-segmented neutrophils were found to have statistically significant (P value < 0.001) relationship with vitamin B12 deficiency. The relationship between vitamin B12 deficiency with either type of diet and anemia was statically insignificant (P > 0.05). The prevalence of vitamin B12 deficiency among rural adolescent girls in Mysuru is high. Other causes of nutritional anemia apart from iron deficiency, such as vitamin B12 deficiency, must be considered in the etiology of anemia and optimally treated. It is recommended to further strengthen the adolescent national health programs and food fortification programs.

A Comparative Analysis of Serum Interleukin-6 Levels in Children with Febrile Seizures and Febrile Controls.

Background Febrile seizures (FSs) are the common presentations of seizures in childhood. Activation of cytokine network plays a significant role in the genesis of FSs. Interleukin (IL)-6 is often considered as key cytokine in the generation of FSs. Objectives To compare the serum IL-6 levels in children between simple febrile seizures (SFSs) and febrile controls (FCs). Materials and Methods This hospital-based prospective cross-sectional study was conducted in JSS Hospital, Mysuru, during a period of 21 months. A total of 83 children were included in the study. Out of which, 38 were cases of SFSs and 45 were FCs without seizures. Serum IL-6 levels were estimated in both SFS and FC groups. Results Serum IL-6 levels were increased among children with SFSs (mean = 608.15 pg/mL) when compared with FCs (mean = 342 pg/mL), but the results are not statistically significant ( p = 0.165). In SFS and FC groups, percentage of subjects with IL-6 levels >50 pg/mL is 31.6 and 44.4%, respectively ( p = 0.16). Conclusion Serum IL-6 levels are higher in children with SFSs compared with FCs. However, this difference did not reach statistical significance.

Etiology of community acquired pneumonia among children in India with special reference to atypical pathogens.

OBJECTIVES: The aim is to identify the etiology of community acquired pneumonia in children with special reference to atypical bacteria and viruses. MATERIALS AND METHODS: A total of 94 pneumonia children were enrolled in the study. Sixty-seven did not have an etiological diagnosis by conventional culture. These children were subjected to immunofluorescence assay by Pneumoslide IgM. RESULTS: Ninety-four children were evaluated for etiology by conventional culture. Twenty-seven of them had the bacteriological diagnosis. Rest 67 were further analyzed for causative organism using Pneumoslide immunofluorescence test. Among this group, 38 (56.7%) had etiological diagnosis. Atypical bacteria were identified in 23 cases, most common being Mycoplasma pneumoniae and which was more common between 5 months and 2 years of age. Viruses were identified in 19 cases, and the most common virus was Respiratory syncytial virus. Mixed pathogens were identified in five children., M. pneumoniae was the common offending agent. CONCLUSIONS: Atypical bacteria and viruses play an important role as etiological agents in pneumonia in children. Pneumoslide IgM is useful for rapid detection of atypical bacteria and viruses.

Hepatitis A in children- clinical course, complications and laboratory profile.

OBJECTIVE: To study the course and complications of hepatitis A in children. METHODS: Seventy eight children diagnosed as acute viral hepatitis A by IgM antiHAV were prospectively studied for involvement of other systems and complications. RESULTS: The mean age of children was 7.85 ± 3.4 y. Jaundice was present in all the patients as this was the inclusion criteria. Fever was present in 82.1 %, hepatomegaly in 98.7 % and splenomegaly in 39.7 %. More than 5 fold rise in Aspartate transaminase (AST) and Alaninetransaminase (ALT), were seen in 62 cases (79.5 %) and 55 cases (70.5 %) respectively. Coagulopathy (Prothrombin time INR > 1.5) was observed in 12 cases (15.4 %) and abnormal APTT in 10 cases (12.8 %). Thrombocytopenia was observed in 5.1 % of children and 8.9 % had more than 2 hematological abnormalities. Ascites was noted in 35 cases (44.9 %), gallbladder wall thickening in 32 cases (41 %) and pleural effusion in 11 cases (14.1 %). Acute renal failure, acute glomerulonephritis and acute pancreatitis were present in 1 case (1.3 %) each. Raised CK-MB values more than 3 times the normal was noted in 5 cases (6.4 %). On follow up, most of the children recovered completely by 2 mo and prolonged cholestasis was observed in 2 of them. In the present study mortality was 1.3 % and it was attributable to fulminant hepatic failure. CONCLUSIONS: Eventhough hepatitis A infection is a self-limiting disease, extrahepatic manifestations and mortality are not uncommon. All cases should be followed up till complete recovery and only a strong index of suspicion will enable us to recognize the complications.

Infantile Alexander disease: A rare leukodystrophy.

Infantile Alexander disease (AD) is a rare leukodystrophy characterized by its early onset within 2 years of life and clinically presents with macrocephaly, seizures, and retarded psychomotor development. Magnetic resonance imaging (MRI) shows characteristic symmetric white matter abnormalities with frontal predominance. We present a case of infantile AD with typical clinical characteristics and MRI features.

Coinfection with dengue and chikungunya--a case report.

Dengue fever outbreaks are reported from India since last 10 years. Since 2005, chikungunya is also causing massive outbreaks in India and other parts of Asia. Both viruses are transmitted by aedes genus and both viruses can re-emerge in many regions due to climatic changes. The clinical presentation of both arthropod borne diseases are similar. Here a concomitant infection of chikungunya and dengue is reported in an 8-year-old child.

Prevalence and annual risk of tuberculosis infection in rural Mysore.

We carried out a tuberculin survey among 5-10 years old children in rural Mysore (n=1026) to estimate the annual risk of tuberculosis infection (ARTI). 90.8% of them had BCG scar. The prevalence of infection was estimated as 13.3% with 95% CI of 11.4-15.5 and ARTI as 1.38%. These figures are comparatively higher than what is reported from other places in India.
