Prediction of batch sorption of barium and strontium from saline water.

Celestite and barite formation results in contamination of barium and strontium ions hinder oilfield water purification. Conversion of bio-waste sorbent products deals with a viable, sustainable and clean remediation approach for removing contaminants. Biochar sorbent produced from rice straw was used to remove barium and strontium ions of saline water from petroleum industries. The removal efficiency depends on biochar amount, pH, contact time, temperature, and Ba/Sr concentration ratio. The interactions and effects of these parameters with removal efficiency are multifaceted and nonlinear. We used an artificial neural network (ANN) model to explore the correlation between process variables and sorption responses. The ANN model is more accurate than that of existing kinetic and isotherm equations in assessing barium and strontium removal with adj. R2 values of 0.994 and 0.991, respectively. We developed a standalone user interface to estimate the barium and strontium removal as a function of sorption process parameters. Sensitivity analysis and quantitative estimation were carried out to study individual process variables' impact on removal efficiency.

Association of Amelogenesis Imperfecta and Bartter's Syndrome.

Bartter's syndrome is an autosomal recessive renal tubular disorder characterized by hypokalemia, hypochloremia, metabolic alkalosis, and hyperreninemia with normal blood pressure. Bartter's syndrome is associated with hypercalciuria and nephrocalcinosis. Amelogenesis imperfecta (AI) is a group of hereditary disorders that affect dental enamel. AI could be part of several syndromes. The enamel renal syndrome is the association of AI and nephrocalcinosis. We report two patients of AI with Bartter's syndrome.

Oral myiasis in children.

Oral myiasis is a rare condition in humans and is associated with poor oral hygiene, severe halitosis, mouth breathing during sleep, mental handicap, cerebral palsy, epilepsy, anterior open bite, incompetent lips, and other conditions. In this report, a 14 year-old boy who had an orofacial trauma in the maxillary dentoalveolar region,which was neglected, has been described. There was a deep lacerated wound on the upper vestibule which was infected and maggots were found on the same wound. The clinical features, management, treatment are discussed and relevant literature is reviewed.

A comparative study of retentive strengths of zinc phosphate, polycarboxylate and glass ionomer cements with stainless steel crowns - an in vitro study.

An in vitro study was conducted to compare the retentive strengths of zinc phosphate, polycarboxylate and glass ionomer cements using Instron universal testing machine. Thirty preformed and pretrimmed stainless steel crowns were used for cementation on 30 extracted human primary molars which were divided into three groups of 10 teeth in each group. Then the teeth were stored in artificial saliva and incubated at 37°C for 24 h. A load was applied on to the crown and was gradually increased till the crown showed dislodgement, and then the readings were recorded using Instron recorder and analyzed for statistical significance. The surface area of crown was measured by graphical method. The retentive strength was expressed in terms of kg/cm 2 , which was calculated by the equation load divided by area. Retentive strengths of zinc phosphate (ranged from a minimum of 16.93 to amaximum of 28.13 kg/cm 2 with mean of 21.28 kg/cm 2 ) and glass ionomer cement (minimum of 13.69 - 28.15 kg/cm 2 with mean of 20.69 kg/cm 2 ) were greater than that of polycarboxylate cement (minimum of 13.26 - 22.69 kg/cm 2 with mean of 16.79 kg/cm 2 ). Negligible difference (0.59 kg/cm 2 ) of retentive strength was observed between zinc phosphate (21.28 kg/cm 2 ) and glass ionomer cements (20.69 kg/cm 2 ). Glass ionomer cements can be recommended for cementation of stainless steel crowns because of its advantages and the retentive strength was almost similar to that of zinc phosphate cement.

Burden of morbidities and the unmet need for health care in rural neonates--a prospective observational study in Gadchiroli, India.

BACKGROUND: Majority of the neonates in developing countries are born and cared for in rural homes but the available information is mostly hospital based. OBJECTIVES: To estimate: (i) the incidence of various neonatal morbidities and associated case fatality in home-cared rural neonates, (ii) proportion of neonates with indications for health care, and (iii) the proportion who actually receive it. DESIGN: Prospective observational study. SETTING: Rural homes. METHODS: Neonates in 39 study villages in the Gadchiroli district (Maharashtra, India) were observed during one year (1995-96) by 39 trained female village health workers at birth and during neonatal period (0-28 days) by making eight home visits. A physician checked the data and the morbidities were diagnosed by a computer program. Vital statistics in these villages was independently collected. RESULTS: Out of 1016 live births, 95% occurred at home and 763 (75&%) neonates were observed. The agreement between observations by health workers and physician was 92%. Total 48.2& neonates suffered high risk morbidities (associated case fatality >10%), 72.2% suffered low risk morbidities, and 17.9% gained inadequate weight (less than 300 g). Seventeen percent neonates developed clinical picture suggestive of sepsis. Though 54.4% neonates had indications for health care and 38 out of total 40 neonatal deaths occurred in these, only 2.6% received medical attention. The neonatal mortality rate was 52.4/1000 live births. CONCLUSION: Nearly half of the neonates in rural homes developed high risk morbidities ten times the neonatal morbidity rate and needed health care but practically none received it. The magnitude of care gap suggests an urgent need for developing home-based neonatal care to reduce neonatal morbidities and mortality

Effect of home-based neonatal care and management of sepsis on neonatal mortality: field trial in rural India.

BACKGROUND: Neonatal care is not available to most neonates in developing countries because hospitals are inaccessible and costly. We developed a package of home-based neonatal care, including management of sepsis (septicaemia, meningitis, pneumonia), and tested it in the field, with the hypothesis that it would reduce the neonatal mortality rate by at least 25% in 3 years. METHODS: We chose 39 intervention and 47 control villages in the Gadchiroli district in India, collected baseline data for 2 years (1993-95), and then introduced neonatal care in the intervention villages (1995-98). Village health workers trained in neonatal care made home visits and managed birth asphyxia, premature birth or low birthweight, hypothermia, and breast-feeding problems. They diagnosed and treated neonatal sepsis. Assistance by trained traditional birth attendants, health education, and fortnightly supervisory visits were also provided. Other workers recorded all births and deaths in the intervention and the control area (1993-98) to estimate mortality rates. FINDINGS: Population characteristics in the intervention and control areas, and the baseline mortality rates (1993-95) were similar. Baseline (1993-95) neonatal mortality rate in the intervention and the control areas was 62 and 58 per 1000 live births, respectively. In the third year of intervention 93% of neonates received home-based care. Neonatal, infant, and perinatal mortality rates in the intervention area (net percentage reduction) compared with the control area, were 25.5 (62.2%), 38.8 (45.7%), and 47.8 (71.0%), respectively (p<0.001). Case fatality in neonatal sepsis declined from 16.6% (163 cases) before treatment, to 2.8% (71 cases) after treatment by village health workers (p<0.01). Home-based neonatal care cost US$5.3 per neonate, and in 1997-98 such care averted one death (fetal or neonatal) per 18 neonates cared for. INTERPRETATION: Home-based neonatal care, including management of sepsis, is acceptable, feasible, and reduced neonatal and infant mortality by nearly 50% among our malnourished, illiterate, rural study population. Our approach could reduce neonatal mortality substantially in developing countries.

PIP: The article presents the effect of home-based neonatal care and management of sepsis on neonatal mortality in the Gadchiroli district of India. The study responds to the growing need for the reduction of neonatal mortality rate in developing countries. Sample population involved 39 intervention and 47 control villages in the Gadchiroli district. Baseline data for 2 years (1993-95) were collected from these districts. Neonatal care was introduced in the intervention villages in 1995-98, wherein village health workers trained in neonatal care made home visits and managed sepsis and other neonatal problems. Other workers recorded all births and deaths in the intervention and the control area (1993-98) to estimate mortality rates. Findings showed that the net percentage reduction in the third year of intervention for the neonatal mortality rate was 25.5 (62.2%); for the infant mortality rate, 38.8 (45.7%); and for the perinatal mortality rate, 47.8 (71.0%). Case fatality in neonatal sepsis declined from 16.6% before treatment to 2.8% after treatment by village workers (p 0.01). The article concludes that home-based neonatal care, including management of sepsis could reduce neonatal mortality substantially in developing countries.
