Correlation between single pre delivery symphysis-fundal height beyond 36 weeks of gestation and birth weight of newborn after delivery

Background: Accurate assessment of fetal weight is important for optimal obstetric management of labouring mothers. Among the methods of fetal weight estimation, symphysis-fundal height (SFH) measurement is inexpensive and non-invasive readily available simple and acceptable procedure of fetal weight estimation. On the other hand, high rate of low birth weight is one of the causes of high perinatal mortality in our country. Objective was to assess fetal birth weight by measuring symphysis-fundal height.Methods: This cross-sectional observational study was conducted in the department of obstetrics and gynaecology, Dhaka Medical College Hospital, Dhaka from July 2017 to June 2018. Total 200 consecutive pregnant women of gestational age more than 36 weeks were selected as per inclusion and exclusion criteria. The fetal birth weight was measured before delivery of the foetus by measuring SFH and using the formula and was compared with actual birth weight.Results: Maximum (35.5%) pregnant mother were in age group 21-25 years followed by 29.5% in 26-30 years, 25.5% in 31-35 years and 9.5% in >35 years age group and mean age was 28.27±4.95 years. Mean weight of new born was 2.81±0.61 kg. Mean symphysis-fundal height 32.76±3.73 cm and maximum (48.5%) pregnant mother had SFH in 35-36 cm group, followed by 30.5% had ≤30 cm and 21.0% had 31-34 cm in this study. New born birth weight had significant positive correlation with symphysis-fundal height.Conclusions: Symphysis-fundal height has significant positive correlation with birth weight of new born

Efficacy of nebulised L-adrenaline with 3% hypertonic saline versus normal saline in bronchiolitis

Background: Bronchiolitis is one of the most common respiratory diseases requiring hospitalization. Nebulized epineph­rine and salbutamol therapy has been used in different centres with varying results. Objective: The objective of the study was to compare the efficacy of nebulised adrenaline diluted with 3% hypertonic saline with nebulised adrenaline diluted with normal saline in bronchiolitis. Methods: Fifty three infants and young children with bronchiolitis, age ranging from 2 months to 2 years, presenting in the emergency department of Manikganj Sadar Hospital were enrolled in the study. After initial evaluation, patients were randomized to receive either nebulized adrenaline I .5 ml ( 1.5 mg) diluted with 2 ml of3% hypertonic saline (group I) ornebulised adrenaline 1.5 ml (1.5 mg) diluted with 2 ml of normal saline (group II). Patients were evaluated again 30 minutes after nebulization. Results: Twenty eight patients in the group I (hypertonic saline) and twenty five in groupII (normal saline) were included in the study. After nebulization, mean respiratory rate decreased from 63.7 to 48.1 (p<.01), mean clinical severity score decreased from 8.5 to 3.5 (p<.01) and mean oxygen satw·ation increased 94.7% to 96.9% (p<.01) in group I. In group II, mean respiratory rate decreased from 62.4 to 47.4 (p<.01), mean clinical severity score decreased from 7.2 to 4.1 (p<.01) and mean oxygen saturation increased from 94. 7% to 96. 7% (p<.01). Mean respiratory rate decreased by 16 in group I versus 14.8 (p>.05) in group 11, mean clinical severity score decreased by 4.6 in group versus 3 (p<.05) in group, and mean oxygen saturation increased by 2.2% and 1.9% in group and group respectively. Difference in reduction in clinical severity score was statistically significant , though the changes in respiratory rate and oxygen saturation were not statistically significant. Conclusion: The study concluded that both nebulised adrenaline diluted with 3% hypertonic saline and nebulised adrenaline with normal saline are effective in improving respiratory rate, clinical severity score and oxygen saturation in infants with bronchiolitis; and nebulised adrenaline with hypertonic saline is more effective than nebulised adrenaline with normal saline in improving clinical severity score in bronchiolitis

Design and Analysis of Parabolic Trough Solar Water Heating System

Renewable energy technology is one of the prospective sources which can meet the energy demand and can contribute to achieve sustainable development goals. Concentrated collectors are widely used in solar thermal power generation and water heating system also. It is very popular due to its high thermal efficiency, simple construction requirements and low manufacturing cost. This paper is concerned with an experimental study of parabolic trough collector for water heating technology. It focuses on the performance of concentrating solar collector by changing the reflector materials (aluminum sheet, aluminum foil and mirror film). In Bangladesh, it is possible to use low cost solar concentrating technologies for domestic as well as industrial process heat applications. The line focusing parabolic trough collectors have been designed, developed and evaluated its performance by collecting solar radiation, inlet and outlet water temperature, flow rate, efficiency etc

The association of maternal serum CRP level with gestational diabetes mellitus

Gestational diabetes mellitus is a common medical condition during pregnancy that has detrimental effects on maternal health and fetal well-being. Many serum markers are known to be associated with gestational diabetes, a subclinical inflammatory state that liberates inflammatory mediators, acute phase proteins like CRP into the maternal circulation. This phenomenon has invited many researchers to study inflammatory mediators and acute phase proteins as markers of gestational diabetes mellitus.This case-control study was conducted in the Department of Obstetrics and Gynecology of Bangabandhu Sheikh Mujib Medical Univer- sity, Dhaka, between July 2016 and June 2017. The objective of the study was to evaluate the association of serum CRP level with gestational diabetes mellitus. A total of 140 pregnant women who attended the out-patients antenatal clinic at their 2nd and 3rd trimester (13-40 weeks) of pregnancy were enlisted for the study. The case group consisted of 70 pregnant women who were diagnosed with GDM. Similar number of healthy pregnant women were recruited as control. GDM was diagnosed using standard 75 g OGTT. Blood sample was taken from study subjects to estimate the serum CRP level. CRP level up to 5mg/L was taken as normal. Data analysis was done by utilizing SPSS version 16. The mean BMI of the case group women was significantly higher than the mean BMI of the control (p=0.001). The mean CRP level in case was 13.87±10.19 and the mean for CRP for control group was 4.59±2.41. There was an association of raised level of CRP with GDM. Pregnant mothers with raised level of CRP (& gt; 5 mg/L) were 6.1 times more likely to have GDM than mothers with normal level of CRP. The study concluded that a significant association was found between the raised level of CRP and gestational diabetes mellitus. BSMMU J 2022; 15(2): 96-10

Congenital visceral leishmaniasis

Visceral leishmaniasis (kala-azar) is caused by the protozoan parasite Leishmania donovani and transmitted by the bite of infected sand fly Phlebotomus argentipes. Only a few cases of congenital transmission have been reported. We are reporting a 15 days old baby with congenital visceral leishmaniasis and then the literature is reviewed

Role of rotavirus vaccination on G9P[8] rotavirus strain during a seasonal outbreak in Japan

Although two live oral rotavirus (RV) vaccines, Rotarix and RotaTeq, play a critical role toward reducing disease severity, hospitalization, and death rate in RV infections, regular monitoring of vaccine effectiveness (VE) is yet necessary because the segmented genome structure and reassortment capability of RVs pose considerable threats toward waning VE. In this study, we examined the VE by a test-negative study design against G9P[8]I2 strain during a seasonal outbreak in February–May, 2018, in an outpatient clinic in Kyoto Prefecture, Japan. It remains important because G9P[8]I2 strain remains partially heterotypic to these vaccines and predominating in post-vaccination era. During year-long surveillance, RV infections were detected only from February to May. During this outbreak, 33 (42.3%) children out of 78 with acute gastroenteritis (AGE) remained RV-positive, of which 29 (87.8%) children were infected with G9P[8]I2. Two immunochromatographic (IC) assay kits exhibited 100% sensitivity and specificity to detect G9P[8]I2 strain. Only 23.2% children were found to be vaccinated. Yet, significant VE 69.7% (95% CI: 2.5%-90.6%) was recognized against all RV strains that increased with disease severity. Similar significant VE 71.8% (95% CI: 1%-92%) was determined against G9P[8]I2 strain. The severity score remained substantially low in vaccinated children. Our data reveal that vaccine-preventable G9P[8]I2 strain yet may cause outbreak where vaccination coverage remains low. Thus, this study emphasizes the necessity of global introduction of RV-vaccines in national immunization programs of every country
