Role of TaqMan array card in determining causative organisms of acute febrile illness in hospitalized patients.

BACKGROUND: Acute febrile illness (AFI) is a prevalent disease in developing countries that is difficult to diagnose due to the diversity of infectious organisms and the poor quality of clinical diagnosis. TaqMan array card (TAC) can detect up to 35 AFI-associated organisms in 1.5 h, addressing diagnostic demands. In this study, we aimed to evaluate the role of TAC in determining the causative organisms in hospitalized AFI patients. METHODS: The study had a cross-sectional design and enrolled 120 admitted patients with persistent fever for three or more days from the medicine ward of Chittagong Medical College Hospital (CMCH) and Bangladesh Institute of Tropical and Infectious Diseases Hospital (BITID). Blood samples were collected and then subjected to automated BacT/Alert blood culture, microbial culture, TAC assay, and typhoid/paratyphoid test. RESULTS: The total number of study participants was 120, among them 48 (40%) samples showed a positive result in TAC card, 29 (24.16%) were TP positive and nine (7.51%) were culture positive. The number of organisms detected by the TAC card was 13 bacteria, three viruses, one protozoan, and one fungus. The sensitivity and specificity of the TAC assay for different bacterial pathogen compared to blood culture was 44.44%, and 90.99%, respectively. In contrast, the TP test had a sensitivity and specificity of 100% and 80%, respectively, compared to the blood culture test. CONCLUSION: TAC can be a handful tool for detecting multiple organisms in AFI with high specificity which can facilitate early diagnosis of different pathogens contributing to AFI.

ROI-Finder: machine learning to guide region-of-interest scanning for X-ray fluorescence microscopy.

The microscopy research at the Bionanoprobe (currently at beamline 9-ID and later 2-ID after APS-U) of Argonne National Laboratory focuses on applying synchrotron X-ray fluorescence (XRF) techniques to obtain trace elemental mappings of cryogenic biological samples to gain insights about their role in critical biological activities. The elemental mappings and the morphological aspects of the biological samples, in this instance, the bacterium Escherichia coli (E. Coli), also serve as label-free biological fingerprints to identify E. coli cells that have been treated differently. The key limitations of achieving good identification performance are the extraction of cells from raw XRF measurements via binary conversion, definition of features, noise floor and proportion of cells treated differently in the measurement. Automating cell extraction from raw XRF measurements across different types of chemical treatment and the implementation of machine-learning models to distinguish cells from the background and their differing treatments are described. Principal components are calculated from domain knowledge specific features and clustered to distinguish healthy and poisoned cells from the background without manual annotation. The cells are ranked via fuzzy clustering to recommend regions of interest for automated experimentation. The effects of dwell time and the amount of data required on the usability of the software are also discussed.

Identifying individuals with multiple non-communicable disease risk factors in Kenya: a latent class analysis.

OBJECTIVES: Non-communicable diseases (NCDs) are the leading causes of death globally. In Kenya, the number of deaths resulting from NCDs is projected to surpass malaria and tuberculosis by 2030. Studies in Kenya show increasing NCDs; the aim of the present study is to examine the clustering of NCDs and risk factors in Kenya. STUDY DESIGN: This is a cross-sectional study using data from the 2015 Kenya STEPwise Survey. METHODS: This study examined relationships between NCDs (e.g. obesity, hypertension and diabetes) and health behaviours (e.g. sedentary activity, and fruit and vegetable consumption). Survey probability weights, which estimated the sampling design effect, were applied to consider the sampling units, and stratifications were used during sampling so that the results could be generalisable to the national adult Kenyan population. In total, 4350 adults were included in the study sample. RESULTS: Overall, 24.43% of participants were classified as having hypertension, 1.88% as having type 2 diabetes, and 27.94% were classified as being overweight or obese. The best-fit model was a four-class solution. Class 1 is best described as 'young with high NCD risk' and had the highest sedentary activity. Class 2 is best described as 'poor rural with lower NCD risk' with a high chance of smoking and alcohol consumption. Class 3 is best described as 'rural with high NCD risk' and had the highest fruit and vegetable consumption. Class 4 is best described as 'wealthy young urban dwellers with high NCD risk' with a high chance of alcohol consumption and smoking. Individuals in Class 4 had the highest chance (40%) of being overweight/obese, a 2% chance of type 2 diabetes and a 23% chance of having hypertension. CONCLUSIONS: NCDs are clustered in groups with high-risk behaviours. The group with the highest chance of having NCDs also had the highest chance of engaging in high-risk behaviours. The findings of this study suggest that smoking and alcohol consumption increase NCD risk in rural areas. Tailored and targeted interventions are needed to curb the increasing NCD prevalence in Kenya.

Risk factors for acute respiratory infection in children younger than five years in Bangladesh.

OBJECTIVES: Acute respiratory infections (ARIs) are one of the major causes of child morbidity and mortality in the developing world. There is a lack of information regarding ARIs in children in Bangladesh. The study aims to determine the potential risk factors that are associated with ARIs among children younger than 5 years in Bangladesh. STUDY DESIGN: A cross-sectional study design was used. METHODS: Data were retrieved from the 2014 Bangladesh Demographic and Health Survey, which provides data for monitoring indicators in population, health and nutrition. In total, 7032 children (weighted) younger than 5 years were eligible for our analysis. Children with a cough and chest-related short, rapid breathing in the 2 weeks before the survey were considered having an ARI. A binary logistic regression model was used to determine the significant risk factors. RESULTS: The prevalence of ARI was 5.3% (95% confidence interval [CI]: 4.7-6.0) in the sample population. Infants aged 0-11 months (odds ratio [OR] = 2.87, 95% CI: 1.92-4.28), toddlers aged 12-23 months (OR = 2.03, 95% CI: 1.21-3.38) and children aged 24-35 months (OR = 1.67, 95% CI: 1.11-2.50) had a greater risk of ARI than older children. Children of lower economic (OR = 2.03, 95% CI: 1.27-3.27) and middle economic (OR = 1.67, 95% CI: 1.06-2.64) families were also at a higher risk of ARI. Girls (OR = 0.75, 95% CI: 0.56-0.99) had a lower risk of ARI compared with boys. In addition, stunting or slow growth rate in children (OR = 1.42, 95% CI: 1.02-1.97) was significantly associated with ARI. CONCLUSION: Young children, boys and stunted children are at greater risk of ARI. Educating mothers on the nutritional needs of children and subsequently reducing stunting due to malnutrition would help in the effort to reduce child morbidity and mortality caused by ARI.

Use of Bioresorbable Vascular Scaffold technology in treating coronary bifurcation lesions: A report about long-term clinical results and review of available literature.

INTRODUCTION: BVS proved safe in humans. ABSORB trials showed them performing similar to Drug Eluting Stents in simple coronary interventions. We assessed a registry of 63 patients with bifurcation lesions, treated by BVS and followed their outcomes up-to 5 years. METHODS: Patients who satisfied the inclusion criteria were included. Data about contact information, baseline characteristics, findings of coronary angiogram, details of their interventional treatment; short and long-term outcomes up till 5 years was collected. RESULTS: Acute feasibility of implantation in bifurcation was high (98 %). Rate of stent thrombosis, acute or sub-acute, was 3.1 %. Rate of re-intervention was 38 %. The average time for an event to occur was 1.6±0.8 years. Over 5 years, 56 % had developed MACE. Patients with MACE were more likely females, hypertensive, smokers, with acute presentations (p=NS), and diabetic (72 % vs 33 % non-diabetic; p=0.002). Patients treated with hybrid strategy of BVS and DES were more likely to develop MACE (64 % vs 49 % for others; P=ns). Patients treated by simple provisional stenting were less likely to develop MACE (45 % vs 60.5 %; p=ns). The average SYNTAX score of MACE patients was 27 vs 20; p=0.06). Diabetes was independently associated with MACE. Hypertension was of borderline statistical significance (2-sided Log rank for Hypertension p=0.06, for Diabetes p=0.01). DISCUSSION: The use of multiple stenting strategies to treat true bifurcation lesions using BVS is feasible with low rate of serious adverse events, albeit on the long run, the rate of re-intervention is high and stringent follow up is required (Tab. 7, Fig. 3, Ref. 37).

Acetaminophen as a Renoprotective Adjunctive Treatment in Patients With Severe and Moderately Severe Falciparum Malaria: A Randomized, Controlled, Open-Label Trial.

Background: Acute kidney injury independently predicts mortality in falciparum malaria. It is unknown whether acetaminophen's capacity to inhibit plasma hemoglobin-mediated oxidation is renoprotective in severe malaria. Methods: This phase 2, open-label, randomized controlled trial conducted at two hospitals in Bangladesh assessed effects on renal function, safety, pharmacokinetic (PK) properties and pharmacodynamic (PD) effects of acetaminophen. Febrile patients (>12 years) with severe falciparum malaria were randomly assigned to receive acetaminophen (1 g 6-hourly for 72 hours) or no acetaminophen, in addition to intravenous artesunate. Primary outcome was the proportional change in creatinine after 72 hours stratified by median plasma hemoglobin. Results: Between 2012 and 2014, 62 patients were randomly assigned to receive acetaminophen (n = 31) or no acetaminophen (n = 31). Median (interquartile range) reduction in creatinine after 72 hours was 23% (37% to 18%) in patients assigned to acetaminophen, versus 14% (29% to 0%) in patients assigned to no acetaminophen (P = .043). This difference in reduction was 37% (48% to 22%) versus 14% (30% to -71%) in patients with hemoglobin ≥45000 ng/mL (P = .010). The proportion with progressing kidney injury was higher among controls (subdistribution hazard ratio, 3.0; 95% confidence interval, 1.1 to 8.5; P = .034). PK-PD analyses showed that higher exposure to acetaminophen increased the probability of creatinine improvement. No patient fulfilled Hy's law for hepatotoxicity. Conclusions: In this proof-of-principle study, acetaminophen showed renoprotection without evidence of safety concerns in patients with severe falciparum malaria, particularly in those with prominent intravascular hemolysis. Clinical Trials Registration: NCT01641289.

Rickettsial Illnesses as Important Causes of Febrile Illness in Chittagong, Bangladesh.

We conducted a yearlong prospective study of febrile patients admitted to a tertiary referral hospital in Chittagong, Bangladesh, to assess the proportion of patients with rickettsial illnesses and identify the causative pathogens, strain genotypes, and associated seasonality patterns. We diagnosed scrub typhus in 16.8% (70/416) and murine typhus in 5.8% (24/416) of patients; 2 patients had infections attributable to undifferentiated Rickettsia spp. and 2 had DNA sequence-confirmed R. felis infection. Orientia tsutsugamushi genotypes included Karp, Gilliam, Kato, and TA763-like strains, with a prominence of Karp-like strains. Scrub typhus admissions peaked in a biphasic pattern before and after the rainy season, whereas murine typhus more frequently occurred before the rainy season. Death occurred in 4% (18/416) of cases; case-fatality rates were 4% each for scrub typhus (3/70) and murine typhus (1/28). Overall, 23.1% (96/416) of patients had evidence of treatable rickettsial illnesses, providing important evidence toward optimizing empirical treatment strategies.

Acute Kidney Injury is More Common in Acute Haemorrhagic Stroke in Mymensingh Medical College Hospital.

Acute kidney injury (AKI) is a common complication after acute stroke and is an independent predictor of both early and long-term mortality after acute stroke. Acute kidney injury is associated with increased mortality in haemorrhagic stroke patients. This cross sectional observational study was conducted in Nephrology, Neuromedicine and Medicine department of Mymensingh Medical College & Hospital, Mymensingh from July 2012 to June 2014. A total of 240 patients with newly detected acute stroke confirmed by CT scan of brain were included in this study. According to this study, 15.42% of acute stroke patients developed AKI. Among the patients with haemorrhagic stroke 21.87% developed AKI while only 13.07% patients with ischaemic stroke developed AKI. So, early diagnosis and management of AKI in patients with acute stroke especially in haemorrhagic stroke is very important to reduce the morbidity and mortality of these patients.

Methanol Induced Toxic Amblyopia--A Case Report.

A 28-year-old man, smoker having history of occasional alcohol intake--was admitted in the Department of Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU) with gradual diminution of vision in both eyes 10 days after consumption of homemade alcoholic beverage in a wedding ceremony. His initial acuity of vision was limited to no perception of light in right eye and hand movement in left eye. Fundus examination revealed pale optic discs in both eyes. The patient was treated with Injection Methylprednisolone 1000 mg intravenous slowly over 1 hour for 3 consecutive days. This was followed by oral prednisolone 60 mg daily for 14 days and then gradually tapered over 4 weeks. The patient also received Injection Hydroxycobalamine and Injection Folinic Acid for 2 weeks. On the 3rd day of treatment there was perception of light in the right eye and on the 10th day the visual acuity improved to hand movement. In the left eye, the visual acuity gradually improved to 6/60 on 3rd day and on 10th day improved to 6/24. Four weeks later, the visual acuity had recovered in both eyes to 6/18. Combination of intravenous and oral steroid along with vitamin B1 and folinic acid has been found effective in treating severe methanol induced optic neuropathy.

Precocious puberty presenting with menarche at the age of 6 years - a case report.

Precocious puberty or central precocious puberty can be very confusing and truly unexpected. After all who know children could go into puberty too early? There is treatment for this condition. Present report has stated that central precocious puberty is becoming more frequent. Many factors may contribute to children who exhibit signs of early precocious puberty. Here we are reporting a case of premature menarche of 6 years old girl who initially presented with continuous per vaginal bleeding for 3 months as a onset of menarche later on after clinical examination and investigations she was diagnosed a precocious puberty due to juvenile premature hypothyroidism. After the successful treatment with thyroxin, level of TSH gradually was decreased and subsequently normal. There after per vaginal bleeding stopped and clinically improved.

Association of infertile patients having polycystic ovarian syndrome with recurrent miscarriage.

Polycystic ovarian syndrome (PCOS) has a pivotal role in the development of various complications during pregnancy. Polycystic ovarian syndrome women having elevated LH and hyper insulineuia may be at increased risk of miscarriage. The study was done to find out the recurrent pregnancy loss among the PCOS patient. This was a cross sectional case control study in total 100 infertile patients between age 20-40 years attending BSMMU out patient Department from July 2011 to June 2012, among them 50 infertile patients with PCOS regarding as a case and 50 infertile patients without PCOS selected as a control. Regarding case (infertile patients with PCOS) shows 20(40%) recurrent miscarriage and among control (infertile patients without PCOS) shows recurrent miscarriage 6(12%). And also among case group shows insulin resistance 8(16%) and control group insulin resistance 1(2%). Six (75%) abortion occur among PCOS with insulin resistance and 5(62.5%) abortion occur among PCOS with raised testosterone level. It is observed that recurrent miscarriage is higher in PCOS group. And also concluded that insulin resistance and raised testosterone level is responsible for this condition. So, further large scale study would be needed to reduce the chance of recurrent pregnancy loss by treatment with insulin sensitizer in case of obese PCOS with insulin resistance patient.

Correlation between grades of intraventricular hemorrhage and severity of hypoxic ischemic encephalopathy in perinatal asphyxia.

This study was done to find out the correlation between various grades of Intraventricular Hemorrhage (IVH) and stages of HIE in perinatal asphyxia and to determine the short-term outcome of the affected baby. This observational study was conducted in Neonatal ward of Dhaka Shishu Hospital (DHS) and Dhaka Medical College Hospital for period of 37 months from January 2004 to January 2007. Total 189 perinatally asphyxiated babies were enrolled for HIE staging and cranial Ultrasonogram (USG) to find out grades of IVH. Finally 178 newborns were fulfilling all the necessary criteria for statistical analysis of the collected data on prescribed questionnaire. Among 178 perinatally asphyxiated newborns HIE stages - I, II, III were 50(28%), 10(56%) and 28(16%) respectively. Out of this 178 neonates total 50(28%) developed various grades IVH. Grades of IVH, I, II, III, IV were 15(30%), 18(36%), 10(20%) and 7(14%) respectively. There was significant correlation between the severity of HIE staging and grades of IVH. Short term outcome was poor in HIE-III, IVH grade III and IV. There is a direct relationship between different grades of IVH and stages of HIE. That is more the severe stages of HIE there is more chances to develop severe grades of IVH, Immediate morbidity and mortality is dependent on the grades of IVH and severity of stages of HIE.

Clinico-Pathological Profiles of Multiple Myeloma Patients in a Tertiary Care Hospital.

Multiple myeloma (MM), mature B-cell lineage neoplasm, is characterized by abnormal clonal proliferation of plasma cells and presence of monoclonal protein (M protein). The study was conducted to reveal presenting features, laboratory findings, Eastern Cooperative Oncology Group (ECOG) performance status and skeletal survey on patients with multiple myeloma. This descriptive, cross-sectional study was carried out in the Department of Haematology, Dhaka Medical College Hospital, Dhaka, Bangladesh from January 2019 to July 2020 with a sample size of 81. Data were collected in a case record form after obtaining informed verbal consent from patients and /or their legal guardians. Relevant ethical issues and data quality assurance were taken into consideration. Data were analyzed with SPSS, Version 25.0 with presentation in figures and tables with frequency, percentage, mean and standard deviation based on data nature. Statistical tests were carried out as appropriate with 5.0% level of significance for assessing statistical association. Mean age of the patients was 58.9±12.0 years. Male female ratio was 2:1. 35(43.2%) patients were smokers with only 2(2.5%) had family history of haematological malignancies. Bone pain (72.8%) was the most common presenting feature, while hypertension (59.1%), diabetes mellitus (29.5%), respiratory illness (11.3%) and cardiac disease (11.4%) were the common co-morbidities. Most common ECOG performance status was ECOG-1(48.1%). Mean haemoglobin (Hb) was 9.4±2.3gm/dl and mean erythrocyte sedimentation rate (ESR) was 89.5±42.1 mm in 1st hour. Mean serum creatinine level was 2.0±1.85 mg/dl and ≥2.0mg/dl in 42(34.2%). Among 50 documentation serum lactate dehydrogenase (LDH) was raised in 18(36.0%). Mean serum calcium level was 9.6±1.8mg/dl >11.0mg/dL in 10(14.5%) cases. Serum albumin <3.5gm/dl in 37(49.3%), ß2-microglobulin >5.5mg/dl in 37(57.8%) cases, International staging system (ISS) stage III was in 59.4% and Bence Jones Protein (BJP) was present in 46.7% cases. Lytic lesions were present in 75.0%, In 38(74.5%) patients vertebrae were involved, while in 18(35.2%) ribs were involved, in 14(27.5%) patients skull was involved and in 3(5.9%) patients involved bones were femur, humerus, sternum and scapula. Mean plasma cells percentage was 62.1±24.9%. Immuno-Fixation Electrophoresis (IFE) revealed IgG (72.7%), IgA (18.2%), Free light chain (FLC) (9.1%). FLC ratio was ≥100 in 29.0% cases. Significant statistical association was observed between serum creatinine with Hb concentration (p<0.05), serum creatinine level with ISS staging (p<0.05) and serum calcium level (p<0/05), while insignificant association was revealed between BJP present status and serum creatinine level (p>0.05). Bone pain, fatigue, fever and neurological impairment were the common presenting features. Anaemia, renal impairment and skeletal lytic events were the prominent physical findings. ISS staging was statistically associated with serum creatinine level, while serum calcium level was associated with serum creatinine and lytic lesions.

A successful pregnancy outcome following abdominal metroplasty.

A 35 years old lady presented to Out Patients Department of Bangabandhu Sheikh Mujib Medical University for secondary subfertility with history of recurrent abortion. She was diagnosed a case of bicornuate uterus following laparoscopy. After 3 months of her last abortion she was advised for metroplasty. Metroplasty was done, forming a single cavity. Dye test was positive on right side and negative on left side. After 3 months of metorplasty hysterosalphingography (HSG) was done and reports shows bilateral patent uterine tubes. One year after metroplasty. She was pregnant with letrozole and Gonadotrophin. Her pregnancy was diagnosed by ultrasonography and advised for admission. She was on regular antenatal follow up and all investigation was done. Anomaly scan was done at 20 weeks of pregnancy. She was properly immunized. Pregnancy period was uneventful until 37 weeks. At 37 weeks LUCS was done. A female healthy baby was born. APGAR score was 7/10 at 1, 10/10 at 5 minutes, baby weight 2.8kg postpartum period was uneventful. After abdominal metroplasty successful pregnancy outcome was occurred.

Pulmonary alveolar microlithiasis (PAM) in a child.

A 4 year 7 month-old girl of consanguineous parents presented with only fever for 25 days but no cough or respiratory distress. Ches x-ray showed bilateral diffuse nodulo-striate opacities in both lungs. Investigations for any infection were negative including tuberculosis. Thoracoscopic biopsy showed alveolar microliths on histopathology suggesting the diagnosis of pulmonary alveolar microlithiasis (PAM).

Feasibility study of rainwater harvesting system in Sylhet City.

In rural areas in Bangladesh, groundwater is the principal source of water supply. This underground water is available in considerable amount in shallow aquifers. It is free from pathogenic microorganisms and hence water-borne diseases. In plain lands, other than hilly areas, water supply to 97% rural population comes from tube-wells, which is regarded to be a phenomenal achievement in preserving public health. Besides, a dependable water supply system all throughout the country is offset by two factors: (a) high salinity in surface plus groundwater in coastal areas; (b) want of suitable groundwater aquifers in hilly areas and the high cost of setting up tube-wells due to deep underground water table and stony layers. However, presence of arsenic in underground water now poses a serious threat to the success once made in water supply by setting up of manually operated tube-wells in the village areas-the achievement is now on the brink of total collapse. In about 61 districts out of 64, presence of arsenic exceeds a quantity of 0.05 mg/1, a permissible limit as per Bangladeshi water quality standard. Harvesting rainwater can be a pragmatic solution to this problem, which is common in many places in Sylhet especially in the hilly areas on the north eastern part of the city. This can be an alternative source of drinking water because of availability of rainwater from March to October. Heavy rain occurs from end of May till mid September, which is commonly known as the rainy season. This paper focuses on the possibility of harvesting rainwater in rural communities and thickly populated urban areas of Sylhet. It also demonstrates the scopes of harvesting rainwater using simple and low-cost technology. With setting up of a carefully planned rainwater storage tank, a family can have all of its drinking water from rain. Planned use of rainwater through rainwater harvesting in the roof catchments may fulfill the entire annual domestic water demand of a family in the rural areas of Bangladesh.

Monitoring of selected pesticides residue levels in water samples of paddy fields and removal of cypermethrin and chlorpyrifos residues from water using rice bran.

Consumption of pesticides associated foods increased in recent decades in Bangladesh. Most of the pesticides come from paddy, as rice is the main food items here and about 70 % pesticides are used only on paddy fields. Water samples of paddy fields and Kaliganga River of Manikganj district were analyzed to provide base line data on cypermethrin, chlorpyrifos and diazinon residue by using high performance liquid chromatography. Levels of Cypermethrin, chlorpyrifos and diazinon detected in the paddy field water samples were (0.605 ± 0.011 µg/L), (0.06 ± 0.001 µg/L) and (0.039 ± 0.002 µg/L), respectively. 0.11 ± 0.003 µg/L of cypermethrin and 0.012 ± 0.0006 µg/L of chlorpyrifos were also identified in the water samples of Kaligonga River. Diazinon residue was not detected in the river water samples. The detected concentrations of pesticide residues in the river water were below the accepted maximum residue limit (MRL) value of drinking water (0.1 µg/l) adopted by the FAO/WHO Codex Alimentarius Commission. Cypermethrin and chlorpyrifos were chosen for decontamination through rice bran, as it was found in river water. Two gm rice bran could easily decontaminated 95.6 % and 96.4 % of cypermethrin and chlorpyrifos. The result of this study showed that pesticide residue was detected in water samples were below the MRLs value, which can easily be decontaminated through absorption of rice bran.

Assessment of renal function by estimation of fractional excretion of sodium in asphyxiated newborns.

This case control study was conducted in Neonatal unit of Dhaka Shishu (Children) Hospital to assess the validity of fractional excretion of sodium (FENa) as a reliable renal function test in asphyxiated newborns. Seventy five appropriate newborns aged between 0-120 hours were randomized in two groups, (Group I; n=50, cases or study group) and (Group II; n=25, controlled group). Blood urea, serum creatinine, serum electrolytes, urinary electrolytes, creatinine, osmolalities, specific gravity, FENa were estimated. Blood urea, Serum creatinine and FENa are increased in perinatal asphyxia. Controls were selected from newborns who had spontaneous breathing immediately after birth and with Apgar score >8 to 10 at 5 minutes. Mean blood urea and serum creatinine were raised in asphyxiated newborn. Blood urea mean±SD was 7.1±3.1mmol/L and serum creatinine mean±SD was 120.8±73.6µmmol/L. Thirty four percent (34%) patients had raised level of blood urea and serum creatinine both, 18% patients had raised (>2.5%) FENa and 48% patients had raised blood urea in asphyxiated newborns. Hyponatremia was also found in asphyxiated newborns. Urinary sodium and creatinine excretion were also higher in the asphyxiated newborns than non asphyxiated newborns. Urinary volume and osmolality were similar in cases and controls. In this study 24% patients died, of which 62.5% were in HIE stage 3, 4.16% were in HIE stage 2 and 1% was in HIE stage 1. Elevated level of serum creatinine (130.0±60.0) and FENa (2.9±1.4) were found in dead patients. Oliguria (0.99±0.6) was also found in dead asphyxiated newborns. Increase in fractional excretion of sodium (FENa) is shown to be directly related to the degree of renal impairment which is again directly related to the degree of asphyxia in the newborns. FENa can be used as an indicator of renal tubular dysfunction in the asphyxiated newborns.

Breastfeeding and cognitive development of children: assessment at one year of age.

Breastfeeding is the fundamental component of child survival strategy. It significantly influences neurological development of children. The study was conducted to assess whether exclusive and prolonged breastfeeding improves children's cognitive development, including low birth weight (LBW) babies, in a developing country setting like Bangladesh. This observational study was done on a cohort of newborn infants who were discharged from the special care baby unit of Dhaka Shishu Hospital during January 2006 to December 2008 with proper counseling about exclusive and prolonged breastfeeding. Their neuro-developmental follow-up was started at 4 weeks postnatal age and continued at 3-monthly intervals up to 1 year of age. At each visit, cognitive development was assessed using the Bayley Scales of Infant Development (BSID II). Cognitive development was compared between the babies of exclusive vs. non exclusive breastfeeding, normal weight vs. low birth weight and male vs. female babies. A total of 105 cases were successfully followed-up during this period. Out of these 47(44.8%) babies were exclusively breastfed up to 6 month of age and 58(55.2%) were in nonexclusive group. Overall Psychomotor Development Index (PDI) was slightly more (108.40 ± 23.06 vs. 103.23 ± 19.87) in the exclusive breast fed babies in comparison to nonexclusive breast fed babies, but was significantly more in babies having birth weight >2.5 kg in comparison to those having birth weight of <2.5 kg. Other parameters of cognitive development were more or less same in both normal and LBW groups. Mental and motor development was same in both boys and girls. In behavior ratings, cooperation was significantly high (5.89 ± 2.54 vs. 4.71 ± 3.13, p=0.05) and vocalization (5.89 ± 1.07 vs. 4.58 ± 1.16) was also high, though not significant, in girls than boys.

Effect of short-term recombinant human erythropoietin therapy in the prevention of anemia of prematurity in very low birth weight neonates.

Premature infants especially those with birth weight < 1500 g suffer from Anaemia of prematurity (AOP) and associated problems. Erythropoietin therapy is a safe effective way to prevent and to treat anaemia of prematurity. To evaluate the effect of short-term administration of recombinant human erythropoietin (rHuEPO) with iron and folic acid in very low birth weight (VLBW) neonates in the prevention of anaemia of prematurity. A randomized controlled trial was carried out at Dhaka Shishu Hospital. Sixty preterm very low birth weight (PTVLBW) babies were enrolled in this study. Thirty were assigned to rHuEPO group and 30 as control. Baseline haematologic values were estimated before administration of rHuEPO. From day 7 of life rHuEPO-200 IU/kg/dose subcutaneously every alternate day for 2 weeks was administered to rHuEPO group. All infants in both groups have received oral iron, folic acid from day 14. Clinical and haematological assessment was done at 6 and 10 weeks of life. Baseline clinical characteristics and haematologic values were almost similar in both groups. This study has shown increase in haematological values (haemoglobin and haematocrit) and reduction in the number of blood transfusions during both the 1st and 2nd follow up in rHuEPO group in comparison to control group (p < 0.01). Short-term rHuEPO appears to be very effective in prevention of Anaemia of prematurity.
