Effect of pulsed electric field treated on quality of curd.

Pulsed electric field (PEF) is a potential pre-treatment technique to improve the quality of milk by reducing its microbial load. The present study aims at addressing this issue with respect to a popular fermented dairy product, that is, curd. Milk was treated with high voltage and frequency (55 kV and 90 Hz) square waves of pulse width 900 µs for 100 s. Curd samples were prepared with conventional heat treatment (CHT), PEF-treated milk subjected to CHT (PT-CHT), and PEF-treated milk (PT). PT samples resulted in curd with higher acidity (0.17 ± 0.005% LA) and microbial load (6.65 ± 0.27 log CFUg-1), while the PT-CHT samples resulted in curd with better whey holding capacity. The firmness recorded for CHT, PT-CHT, and PT was 1.15 ± 0.05, 1.32 ± 0.04, and 0.91 ± 0.03 N, respectively. PT-CHT showed a higher viscosity index, that is, 0.207 ± 0.005 g. Sensorial properties showed the acidic nature of PT-curd with greater syneresis and softer texture resulted in its poorer sensory scores for texture. Shelf-life analysis showed no significant difference between curd prepared using the CH and PT-CHT up to 12 days. The study demonstrated the potential of employing PEF with CHT for improving the texture and shelf life of curd without impacting its quality.

Hydrodynamic behavior of bubbles at gas-evolving electrode in ultrasonic field during water electrolysis.

In electrochemical processes, gas bubbles on the electrode can cause an increase in both overpotential and ohmic voltage drop which leads to higher energy consumption. Applying power ultrasound during water electrolysis can help to reduce the overpotential, enhance mass transfer, and save energy. In this study, we investigated the effect of ultrasound (20 kHz) on the hydrogen evolution reaction (HER) on a stainless steel plate with varying concentrations of NaOH solutions at 298 K, using linear sweep voltammetry (LSV). We especially focused on understanding the bubble behavior on the stainless steel plate during HER using high-speed imaging in ultrasonic field. When ultrasound was applied to solutions with NaOH concentrations of 0.1, 0.5, 1 M, the current density increased by about 9.0, 5.9, 2.8 %, respectively. As the ultrasound irradiation began, the bubbles tended to hover around on the electrode surface, coalescing with other bubbles, rather than rising. When the size of the coalesced bubbles became too large to stay on the surface of the electrode, they were expelled from the ultrasonic field. The repeated collapse and coalescence of these bubbles was observed while they were rising. The velocity increased about 2 times when ultrasound irradiation began, and increased by more than 6 times in the ultrasonic field. More nucleation of bubbles was observed on the electrode in the ultrasonic field. Using ultrasound reduced the critical diameter of bubbles which detached from the electrode, from 58.0 to 15.9 µm, and the residence time of the bubbles, from 533 to 118 ms. Further, when the ultrasound was applied, the mean diameter of bubbles decreased from 71.8 to 17 µm. Hence, bubble coverage on the electrode surface decreased from 8.3 to 1 % despite an increase in the total number of bubbles. As a result, ultrasound was found to be effective for hydrogen production during water electrolysis, increasing current by the faster removal of gas from the stainless steel plate.

Genetic and non-genetic factors affecting semen production and quality characteristics of Gir cattle breed under semi-arid climate.

AIM: This study aims to evaluate genetic and non-genetic factors influencing semen production potential of Gir bulls. MATERIALS AND METHODS: Data on semen quantity (n=6911) and quality (n=466) available from January 2011 to December 2018 at BAIF's frozen semen station, Jind, Haryana, India, were utilized for the study. Factors, namely, season of collection, age at collection, and bull (random effect) were studied for their effect on quantitative and qualitative semen traits. Least square means for the traits were obtained using a general linear model. The effect of age within bull for repeatable traits was analyzed using a longitudinal model with age as the control variable. Multivariate analysis using mixed repeatability model equation was utilized to estimate bull effect correlation (genetic + permanent environmental correlation), phenotypic correlations, and repeatability. RESULTS: The overall least square means of ejaculate volume, sperm concentration, total sperms, initial and post-thaw motility, hypo-osmotic swelling test, and acrosome integrity of frozen semen were 6.62±0.03 ml, 1.22±0.01 109/ml, 8.09±0.05 109/ejaculate, 75.78±0.001%, 55.92±0.0001%, 55.13±0.005%, and 71.08±0.001%, respectively. The season of the collection showed a significant effect on volume, concentration, total sperm, and initial motility. The performance of bulls was superior in summer season, followed by winter and monsoon. Increase in semen attributes during summer season was due to the effect of lower temperature on sensitive stages of spermatogenesis. Age at collection had a significant effect on all semen traits. Volume and total sperm count showed increasing trend while concentration showed a decreasing trend with an increase in age. Motility and quality traits did not show any particular pattern. Individual bulls showed differences in all the semen performance traits with age. The repeatability of the traits ranged from 0.04 (HOST) to 0.58 (acrosome integrity). Bull effect correlation ranged from -0.73 (initial motility and acrosome integrity) to 0.93 (HOST and acrosome integrity). CONCLUSION: Individual bulls showed variation in traits measured over age. The result of the study could be utilized in suggesting suitable management plans to achieve the desired profit by improving semen quality in Gir bulls.

Anatomical Study of the Facial Recess with Implications in Round Window Visibility for Cochlear Implantation: Personal Observations and Review of the Literature.

Introduction Posterior tympanotomy through facial recess (FR) is the conventional and most preferred approach to facilitate cochlear implantation, especially when the electrode is inserted through the round window. The complications of the FR approach can be minimized by proper understanding of the anatomy of the FR. Objective The present study was undertaken to assess the various parameters of FR and round window visibility, which may be of relevance for cochlear implant surgery. Methods Thirty-five normal wet human cadaveric temporal bones were studied by dissection for anatomy of FR and posterior tympanum. Photographs were taken with an 18 megapixels digital camera, which were then imported to a computer to determine various parameters. Results The mean distance from the take-off point/crotch of the chorda tympani nerve (CTN) to the stylomastoid foramen was 4.08 ± 0.8 mm (range of 2.06 - 5.5 mm). The variations in the course of the CTN included origin at the level of the lateral semicircular canal. The mean chorda-facial angle in our study was 26.91° ± 1.19°, with a range of 25° to 28.69°. The mean FR length ranged between 9.4 mm and 18.56 mm (mean of 12.41 ± 2.91mm) and varied with the origin of the CTN and pneumatization of temporal bone. The average maximum width of the FR was 2.93 ± 0.4 mm (range 2.24-3.45 mm) and the mean width of the FR at the level of the round window was 2.65 ± 0.41 mm. Conclusion The FR approach provides good access to the round window membrane in all cases. In some cases, table adjustment is required.

Effect of mechanical and chemical treatments of arecanut (areca catechu L.) fruit husk on husk and its fibre.

Arecanut husk, a biomass is generated during extraction of nut and is stored in heaps in the backyards of processing units. Arecanut husk presently has no industrial/commercial applications and is a cause of major environmental hazards. Arecanut husk is rich in good quality lingo-cellulosic fibres which have potential applications in various fields. Presently there is no proper process and machinery available to extract these fibres on a mass scale. Designing such machinery requires characterisation of husks, bonding force between fibres and the shell, etc. The aim of the present study is develop suitable mechanical and chemical treatments to facilitate easy extraction of fibres and also to study the effects of theses pretreatments on tensile property of fibres. The variety used was Shreevardhini. It was noticed that the pretreatments of husk had significant effect on fibre separation. Highest fibre recovery of about 57% was achieved with pressed husks soaked in water for 24 h. Detachment force required for fibre / fibres separation from husk was least in 2.5% KOH treated husks. There was no adverse effect of pretreatments on tensile strength of fibres. Pressing of husks resulted in maximum fibre recovery due to weakening of bonds, hence pressing of arecanut husk before mechanical fibre extraction is recommended, whereas chemical pretreatment of husks with KOH is not recommended.

Efficacy and tolerability of treatment with single doses of diethylcarbamazine (DEC) and DEC plus albendazole (ABZ) for three consecutive years in lymphatic filariasis: a field study in India.

Lymphatic filariasis (LF) affects 73 countries, causes morbidity and impedes socioeconomic development. We had found no difference in safety and micro (Mf) and macro filarial action of single-dose diethylcarbamazine (DEC) and DEC + albendazole (ABZ) in an F01 study done in India (year 2000). There was a programmatic need to evaluate safety and efficacy of multiple annual treatments (F02). Subjects (155) from the F01 study, meeting inclusion-exclusion criteria, were enrolled in F02 and treated with further two annual doses of DEC or DEC + ABZ. Efficacy was evaluated for Mf positivity by peripheral smear (PS) and nucleopore (NP) filter, circulating filarial antigen (CFA) and filarial dance sign (FDS) positivity and Mf count at yearly follow-up. Safety was assessed for 5 days after drug administration. Total of 139 subjects evaluated for efficacy (69 DEC and 70 DEC + ABZ group). Mf positivity prevalence declined progressively by 95% (PS), 66% (NP), and 95% (PS) and 86% (NP); CFA positivity prevalence declined by 15% and 9%; FDS by 100% each; Mf count declined by 75.5 and 76.9% with three annual treatment of DEC and DEC + ABZ, respectively. Addition of ABZ did not show any advantage over DEC given as three annual rounds for LF. DEC and DEC + ABZ were well tolerated. There was no correlation between result of CFA and FDS, (both claimed to be indicative of adult worm). Analysis of published studies and our data indicate that macrofilaricidal effect of DEC/DEC + ABZ may be seen in children and not adults, with three or more annual dosing.

Social capital and adverse treatment outcomes of tuberculosis: a case-control study.

SETTINGS: 'Social capital' refers to social norms, relationships, networks and values that affect the functioning and development of society. Social capital influences health positively, but its role in the treatment outcomes of tuberculosis (TB) is not known. OBJECTIVES: To study the role of social capital in determining adverse TB treatment outcomes. DESIGN: Of 516 patients registered under the Revised National Tuberculosis Control Programme in 2014 in Wardha Tuberculosis Unit, Wardha, India, we included 88 patients with adverse treatment outcomes as cases and 187 controls from among those without adverse outcomes. Multiple logistic regression was used to compare standardised Z-scores. RESULTS: A greater proportion of controls than cases belonged to higher quartiles of social capital and its domains than cases, and the mean standardised Z-score was also consistently higher among controls than cases. Respectively 47% and 15% of cases and controls were in the poorest quartile of social capital, whereas respectively 10% and 33% of cases and controls were in the richest quartile. Each unit increase in Z-score of overall social capital reduced the odds of adverse treatment outcomes by 63.1%. CONCLUSION: Appropriate interventions for building social capital for TB patients and linking them with the programme would improve programme performance.

Pulmonary Functions, Oxidative Stress and DNA Damage in Workers of a Copper Processing Industry.

BACKGROUND: Occupational exposure to excessive level of copper results in many adverse health effects. OBJECTIVE: To measure pulmonary function, oxidative stress, and extent of DNA damage in workers of a copper processing industry. METHODS: 30 men working in a copper processing industry and 30 men matched for age and socioeconomic status (comparison group) were included in this study. Pulmonary function test parameters were measured for all participants. Serum malondialdehyde (MDA), ferric reducing ability of plasma (FRAP), glutathione (GSH) content in RBCs and 8-OHdG were assayed by ELISA. Extent of DNA damage in leucocytes was assayed by comet assay. RESULTS: Pulmonary function parameters, FVC, FEV1, PEFR, and MVV measured in workers were significantly (p<0.05) lower than those observed in the comparison group. Compared to the comparison group, MDA was significantly (p=0.002) increased in studied workers; TAOC (p=0.017), and GSH (p=0.020) were significantly lower in workers than the comparison group. There was significant DNA damage in leucocytes in workers compared to the comparison group (difference in olive tail moment p<0.001). PEFR, FEF25-75%, and MEF50% were negatively correlated with MDA. CONCLUSION: The observed DNA damage would be due to increased oxidative stress resulting from excessive exposure to copper.

Pneumatization Pattern in Squamousal Type of Chronic Otitis Media.

To study the pneumatization pattern of mastoid bone in cases of squamousal type of chronic otits media and analyze pneumatization pattern of opposite normal ear in cases of unilateral chronic otitis media (COM). A total of 94 patients (104 ears) between the age group of 7-84 years attending the E.N.T outpatients, inpatients and casualty of Acharya Vinoba Bhave Rural Hospital, Sawangi (Maghe), Wardha, after applying inclusion and exclusion criteria were found suitable and hence selected for the present study and were subjected to bilateral X-ray mastoid (Schuller's view). HRCT temporal bone done in selected 55 patients. On analyzing patients radiologically (X-ray mastoid), it was found that out 104 ears, mastoid was pneumatized in 2 (1.92 %) diploic in 20 (19.23 %) and sclerotic in 82 (78.85 %) ears. Contralateral mastoid of 70 normal ears, mastoid was pneumatized in 30 (42.86 %) diploic in 22 (31.43 %) and sclerotic in 18 (25.71 %) ears. Most of the diseased ear demonstrated non pneumatized mastoid (98.08 %) whereas contra lateral mastoid of 70 normal ear, showed significantly more pneumatization This difference is statistically significant (P value < 0.0001). Significantly more sclerosis and non pneumatization in the ear with COM of squamousal type than the healthy contralateral ear supports the environmental theory.

A Study of VO2 Max and Body Fat Percentage in Female Athletes.

INTRODUCTION: Aerobic capacity of athletes is an important element of success in sports achievements. It is generally considered the best indicator of cardio respiratory endurance and athletic fitness. Body fat percentage affects VO2 max and thus the cardiovascular status of the athletes. The present study was undertaken to assess the VO2 max and body fat percentage in athletes. The secondary objective of the study was to study the relationship between VO2 max and body fat percentage. MATERIALS AND METHODS: Twenty five female athletes of age group 17-22years were selected for the study. VO2 max was determined by Queen's college step test and body fat percentage by skin fold calipers. The VO2 max and body fat percentage were determined in non athletes of same age group for comparison. The statistical analysis was done by Student's t-test and Pearson correlation test. OBSERVATION AND RESULTS: The mean VO2 max in athletic group was 39.62 ± 2.80 ml/kg/min. In non-athletic group, VO2 max was 23.54 ± 3.26 ml/kg/min. The mean body fat percentage in athletes was 24.11 ± 1.83% and in non-athletes it was 29.31 ± 3.86%.The difference in VO2 max and body fat percentage was statistically significant in our study. The VO2 max and body fat percentage in both the groups showed negative correlation by Pearson test but, was not statistically significant. CONCLUSION: The present study showed a statistically significant higher VO2 max in female athletes. The study showed a negative correlation between VO2 max and body fat percentage but was not statistically significant.

Dissolution Enhancement of Rosuvastatin Calcium by Liquisolid Compact Technique.

In present investigation liquisolid compact technique is investigated as a tool for enhanced dissolution of poorly water-soluble drug Rosuvastatin calcium (RVT). The model drug RVT, a HMG-Co A reductase inhibitor was formulated in form of directly compressed tablets and liquisolid compacts; and studied for in-vitro release characteristics at different dissolution conditions. In this technique, liquid medications of water insoluble drugs in non-volatile liquid vehicles can be converted into acceptably flowing and compressible powders. Formulated systems were assessed for precompression parameters like flow properties of liquisolid system, Fourior transform infra red spectra (FTIR) analysis, X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), and post compression parameters like content uniformity, weight variation, hardness and friability, disintegration test, wetting time, in vitro dissolution studies, effect of dissolution volume on drug release rate, and estimation of fraction of molecularly dispersed drug in liquid medication. As liquisolid compacts demonstrated significantly higher drug release rates, we lead to conclusion that it could be a promising strategy in improving the dissolution of poor water soluble drugs and formulating immediate release solid dosage forms.

Effect of Tridax procumbens (Linn.) on bile duct ligation-induced liver fibrosis in rats.

The present study was undertaken to clarify whether methanolic extract of Tridax procumbens prevents liver fibrosis in rat. The hepatic fibrosis was induced by 28 days of bile duct ligation in rats. The 4-week treatment with Tridex procumbens reduced the serum aspartate aminotransferase (U L⁻¹), glutamate pyruvate transaminase (U L⁻¹), alkaline phosphatase (IU L⁻¹), lactate dehydrogenase (IU L⁻¹), total bilirubin (mg dL⁻¹), direct bilirubin (mg dL⁻¹) and hydroxyproline (mg gm⁻¹) content in liver and improved the histological appearance of liver section. The results of this study led us to conclude that T. procumbens can reduce the degree of hepatocellular damage and may become antifibrotic agent for liver fibrosis.

Combined Middle Cranial Fossa and Trans-Mastoid Approach for the Management of Post-Mastoidectomy CSF Otorrhoea.

Cerebrospinal fluid (CSF) otorrhoea is an uncommon condition arising from defects in the tegmen and middle cranial fossa. 33 year gentleman presented with post-mastoidectomy CSF otorrhoea of 5 year duration. Imaging finding were suggestive of fracture in the tegmen region. A combined middle cranial fossa/transmastoid was used to repair the defect. Defect was identified in the tegmen plate and it was closed with pedicled pericranial graft, laterally based pedicled temporalis muscle graft reinforced by bone dust and supported with intact mucosal flap. The leak stopped completely following surgery. The patient is doing well at follow up. Repair of these defects need careful analysis of imaging findings to understand pathological anatomy, and a well planned surgical approach to achieve meticulous repair.

Where and how breastfeeding promotion initiatives should focus its attention? A study from rural wardha.

BACKGROUND: In India, the practice of breastfeeding is almost universal, but initiation of breastfeeding is generally quite late and colostrum is discarded. Integrated Management of Neonatal and Childhood Illness (IMNCI) strategy recommended systematic assessment of breastfeeding and emphasized counseling of the mother on proper positioning and attachment of infant to the breast. OBJECTIVE: To assess breastfeeding among mothers of below six months children in rural Wardha. MATERIALS AND METHODS: The present cross-sectional study was undertaken in surrounding 23 villages of Kasturba Rural Health Training Center (KRHTC), Anji. Two Auxiliary Nurse Midwives (ANMs) trained in IMNCI paid house visits to 99 mothers during the study period and undertook the assessment of breastfeeding using IMNCI assessment form for young infants. Auxiliary Nurse Midwives observed and recorded the positioning and attachment of infant to the breast as per IMNCI guidelines. The data were entered and analyzed using Epi_Info (version 6.04d) software package. RESULTS: Most of the deliveries 94 (94.9%) took place in the healthcare facilities. Majority 61 (61.6%) newborn babies had received breastfeeding within half an hour. About half of the mothers had any of the feeding problems like feeding less than eight times in 24 h, giving any other food or drinks or is low weight for age. Significantly more mothers with feeding problems had problems in positioning and attachment of infant to the breast as compared with those mothers who did not have any feeding problems. CONCLUSIONS: In the settings, where practice of institutional delivery is high, the staff of healthcare facility should ensure education of the mothers regarding position and attachment of infant to the breast before discharge from the healthcare facility. At the village level, Village Health Nutrition Day (VHND) can be utilized for health education of future mothers and support for the breastfeeding mothers. The IMNCI assessment form for young infant should also include assessment of positioning of infant.

An evaluation of ROME Camp: forgotten innovation in medical education.

BACKGROUND AND OBJECTIVES: Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sewagram, India's first rural medical institute, has been implementing its community-based public health teaching with the aim of building a physician workforce for the rural poor. For the past four decades, the MGIMS has organized and run the Re-orientation of Medical Education (ROME) camp for final year medical undergraduates at one of the rural centres of the department of Community Medicine. The objectives of the present study were to learn students' perceptions of the value and effectiveness of various components of the ROME camp and learn the factors they perceive facilitate and inhibit learning. METHODS: A mixed-method research design of quantitative (survey) and qualitative (force field analysis) methods was used. The study participants were all 61 of the final year medical undergraduates participating in the ROME camp in 2008. The quantitative data was analyzed using SPSS software package and summative content analysis of the qualitative data was undertaken. RESULTS: Students were generally very positive about all aspects of the camp and its component parts. The greatest consensus (88.9%, on a 0 to 100% scale) was for the contribution to student learning of the visit to the Primary health centre and Sub-centre, as offering direct exposure and interaction with the village-level service providers. There was poorer consensus for students' involvement with the field-based clinics, as this was felt by some not to contribute significantly to their understanding of socio-economic and environmental factors related to cases (78.8%) and their ability to diagnose health problems in resource poor settings (76.5%). The major strength of the camp was felt to be its exposure visits and hands-on experiences in surveys and interaction with village-level health care providers. Students reported poor interactions with teachers in some educational sessions, including the field-based clinics and classes on theories of national health programs. CONCLUSIONS: The curriculum of the ROME camp was generally well regarded by students, but based on their views it should emphasize interactive theory sessions. The ROME scheme can be revitalized in all medical colleges as it is an effective practical approach for teaching public health principles and practice to medical students.

On-line capacity-building program on "analysis of data" for medical educators in the South Asia region: a qualitative exploration of our experience.

BACKGROUND AND OBJECTIVE: In medical education, using the World Wide Web is a new approach for building the capacity of faculty. However, there is little information available on medical education researchers' needs and their collective learning outcomes in such on-line environments. Hence, the present study attempted: 1)to identify needs for capacity-building of fellows in a faculty development program on the topic of data analysis; and 2) to describe, analyze and understand the collective learning outcomes of the fellows during this need-based on-line session. MATERIALS AND METHODS: The present research is based on quantitative (on-line survey for needs assessment) and qualitative (contents of e-mails exchanged in listserv discussion) data which were generated during the October 2009 Mentoring and Learning (M-L) Web discussion on the topic of data analysis. The data sources were shared e-mail responses during the process of planning and executing the M-L Web discussion. Content analysis was undertaken and the categories of discussion were presented as a simple non-hierarchical typology which represents the collective learning of the project fellows. RESULTS: We identified the types of learning needs on the topic 'Analysis of Data' to be addressed for faculty development in the field of education research. This need-based M-L Web discussion could then facilitate collective learning on such topics as 'basic concepts in statistics', tests of significance, Likert scale analysis, bivariate correlation, and simple regression analysis and content analysis of qualitative data. CONCLUSIONS: Steps like identifying the learning needs for an on-line M-L Web discussion, addressing the immediate needs of learners and creating a flexible reflective learning environment on the M-L Web facilitated the collective learning of the fellows on the topic of data analysis. Our outcomes can be useful in the design of on-line pedagogical strategies for supporting research in medical education.

Childhood morbidity, household practices and health care seeking for sick children in a tribal district of Maharashtra, India.

OBJECTIVES: To find out the magnitude of childhood morbidities, health care seeking behavior and explore the status of 'some desired practices' at household level during episodes of illness in two tribal blocks of Chandrapur district. MATERIALS AND METHODS: The present explanatory mixed-method design of quantitative (survey) and qualitative (focus group discussions, FGDs )methods was undertaken in nine Primary health centers of Warora and Bhadrawati blocks in Chandrapur district. The information of 2,700 under-five children on morbidity, health care seeking behavior and some desired practices at household level was collected by paying home visits and using pre-designed and pre-tested questionnaire. The data was entered and analyzed by using SPSS 12.0.1 and C sample program of epi_info (version 6.04d) software package. The conventional content analysis of FGD data was undertaken. RESULTS: The prevalence of morbidities was high among newborns and children. About 1,811 (67%) children had at least one of the morbidities. Private health care providers and village level faith healers were preferred for seeking treatment of newborn danger sings and childhood morbidities. The status of some desired household practices such as frequent feeding and giving extra fluid to drink during episodes of illness was poor. CONCLUSIONS: In conclusion, considering high prevalence of child morbidities and poor status of some desired household practices of caregivers at household level for sick children, household and community IMNCI strategy needs to be implemented to promote child health and nutrition. Apart from this, health care delivery at village level should be strengthened.

Acute childhood morbidities in rural Wardha: some epidemiological correlates and health care seeking.

BACKGROUND: In India, common morbidities among children under 3 years of age are fever, acute respiratory infections, diarrhea. Effective early management at the home level and health care-seeking behavior in case of appearance of danger signs are key strategies to prevent the occurrence of severe and life-threatening complications. OBJECTIVES: To find out the prevalence of acute child morbidities, their determinants and health-seeking behavior of the mothers of these children. SETTING AND DESIGN: The cross-sectional study was carried out in Wardha district of central India. MATERIAL AND METHODS: We interviewed 990 mothers of children below 3 years of age using 30-cluster sampling method. Nutritional status was defined by National Center for Health Statistics (NCHS) reference. Composite index of anthropometric failure (CIAF) was constructed. Hemoglobin concentration in each child was estimated using the 'filter paper cyanm ethemoglobin method.' Using World Health Organization guidelines, anemia was defined as hemoglobin concentration less than 110 g/L. Post-survey focus group discussions (FGDs) were undertaken to bridge gaps in information obtained from the survey. STATISTICAL ANALYSIS: The data was analyzed by using SPSS 12.0.1 software package. Chi-square was used to test the association, while odds ratios were calculated to measure the strength of association. Multiple logistic regression analysis was applied to derive the final model. RESULTS: Anemia was detected in 80.3% of children, and 59.6% of children were undernourished as indicated by CIAF. The overall prevalence of acute morbidity was 59.9%. Children with mild anemia, moderate anemia and severe anemia had 1.52, 1.61 and 9.21 times higher risk of being morbid, respectively. Similarly, children with single, 2 and 3 anthropometric failures had 1.16, 1.29 and 2.27 times higher risk of being morbid, respectively. Out of 594 (60%) children with at least one of the acute morbidities, 520 (87.5%) sought health care, where majority (66.1%) received treatment from private clinics. The final model suggested that anemia and mother's poor educational status are predictors of childhood morbidity. CONCLUSIONS: Nutritional anemia and mother's poor educational status are the most important risk factors of acute childhood morbidity. There is need to revitalize existing health care delivery and child health programs in rural India with emphasis on immediate correction of nutritional anemia.

A comparative study of ceruminolytic agents.

A prospective study was done to access the efficacy of ceruminolytic agents, i.e 2% paradichlorobenzene, 10% sodium bicarbonate, 2.5% acetic acid and normal saline. All score 4 hard impacted ear wax cases in the adult population (>20 years) were accrued for the assessment of the relative efficacy. Upon analyzing the comparative efficacy of four ceruminolytic agents, by taking into consideration three parameters (post) ceruminolytic cerumen score, attempts of syringing required to extrude the cerumen mass, post-ceruminolytic use and appearance of the removed cerumen mass. 2% paradichlorobenzene emerged as the most superior ceruminolytic, closely followed by 10% sodium bicarbonate. 2.5% acetic acid fared moderately while normal saline emerged as the least efficacious ceruminolytic agent.

In-vitro red blood cell partitioning of doxycycline.

OBJECTIVE: In-vitro red blood cell (RBC) partitioning of doxycycline was studied to determine whether doxycycline penetrates RBC and its concentration was assayed keeping in view its high lipophilicity. MATERIALS AND METHODS: Standardization of doxycycline was performed in whole blood and plasma of cattle by microbiological assay using Bacillus subtillis ATCC 6633 as indicator organizm. Actual concentration of the drug was obtained by comparing zone inhibition with standard graph and the extent of partitioning was mathematically calculated. RESULTS: The R(2) value of standard graph for doxycycline was 0.9934 and 0.9727 for plasma and whole blood, respectively. Overall, RBC partitioning of doxycycline was found to be 18.40 +/- 1.70%. CONCLUSIONS: Overall RBC partitioning of doxycycline indicated low penetration into RBC. Plasma is the fluid suggested for pharmacokinetic evaluation of doxycycline.
