Experience of Exchange Transfusion in a Newly Established SCANU at a Tertiary Care Hospital in Bangladesh.

Hyperbilirubinemia is common in neonates. The value of exchange transfusion (ET) is recognized. The procedure has some risks and complications. This descriptive observational cross sectional study was done in the Neonatology department during the period of January 2013 to December 2013. Total 62 patients were studied. ET was done in 47 patients. Among 47 patients, 29(61.7%) were male and 18(38.3%) were female. The most common cause of ET was Rh incompatibility (46.8%). In order of frequency, major findings were ABO incompatibility (25.5%), unidentified (14.9%), Sepsis (6.4%), minor blood group incompatibility (4.3%) and others (2.1%) respectively. Mean Serum bilirubin level was 22±5.1mg/dl. Most common complications following ET were anemia (12.7%), Sepsis (10.6%), and omphalitis (6.4%). The overall mortality observed was 6.4%. The majority of the adverse events associated with ET were treatable.

Iron status in children with febrile seizure.

This hospital based cross sectional analytic study was carried out in department of Pediatrics Dhaka Medical College Hospital and Combined Military Hospital from July 2009 to June 2010 to find out the relationship of iron status with febrile seizure in children. Sixty children aged 6 months to 5 years having febrile seizure were enrolled as cases after taking proper consent by purposive sampling. Sixty age matched children with fever but no seizures were taken as control after taking proper consent. Children having a febrile seizure, developmental delay, hemorrhagic disorder, severe malnutrition or micronutrient deficiency and abnormal CSF findings were excluded from the study. In cases after control of seizure 2 ml of CSF was taken for cytology, biochemistry, Gram & AFB staining. Two milliliter of blood from cases as well as control was collected, released to EDTA bottle for Hb, MCV and MCHC. Again 2 ml of blood was taken in plain test tube for testing serum iron, TIBC and for serum ferritin. Serum iron, TIBC, serum ferritin was estimated by automated analyzer (PENTRA for serum iron, DADE BEHRING for TIBC, IMMULITE 1000 for serum ferritin). There was no significant difference between two groups regarding age (p>0.05), sex (p>0.05). High fever (p<0.001) and continuous fever (p<0.001) was significantly associated with febrile seizure. Seizure was generalized in all with positive family history in 83.3% cases. The Mean±SD of blood Hb (Case 9.8±1.6; Control 10.7±0.9), MCH (Case 22.1±2.3; Control 24.3±3.6) & serum ferritin (Case 55.1±29.3; Control 99.6±81.9) level were significantly low associated with febrile seizure (p<0.05). No significant difference was found between cases and control regarding MCV, serum iron and serum TIBC.

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.

Clinical and Radiological Evaluation of Children Aged 2 Months to 5 Years with Severe Pneumonia According to WHO Guideline.

Pneumonia is the leading cause of morbidity and mortality in children less than 5 years of age in developing countries like Bangladesh. Although WHO guideline classified severe pneumonia by symptoms and signs of the patients, radiological and laboratory investigations were not studied well. There was increasing number of cases of bronchiolitis which meet the criteria of WHO classified severe pneumonia are reported. The objective of the study was to assess the clinical and radiological parameters of severe pneumonia in 2 months to 59 months hospitalized children according to WHO guideline. This cross sectional study was conducted in pediatrics department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July, 2015 to December 2015. Total 150 patients were included in this cross sectional study according to their clinical symptoms. Firstly, the chest x-ray was done in all the patients and radiographs were reviewed by an expert radiologist who was blind about the cases. Then the patients were classified as pneumonia and bronchiolitis according to the clinical features and radiology findings. Majority of the patients 83(55.3%) were between 2-6 months of age and mean age was 7.52±8.87. Maximum 105(70%) patients were male and 45(30%) were female. Most of them 70(47%) came from low middle class family. Regarding clinical features, all patients 150 had cough and chest indrawing. Ronchi found in 135(90%) patients, difficult breathing and fast breathing found in 130(87%) patients, crepitation in 122(81%) patients, wheeze in 93(62%) patients, dull on percussion in 36(21%) patients, bronchial breath sound in 25(17%) patients. Regarding radiological features, lobar consolidation was found in 18(12%) patients, patchy opacities in 42(28%) patients, which were radiological findings of pneumonia, while hyperinflation of lung present in 90(60%) patients, increased translucency in 82(54.6%), increased interstitial marking in 88(58.6%) patients, which were radiological findings of bronchiolitis. A total of 60(40%) admitted cases were diagnosed as pneumonia and 90(60%) cases diagnosed as bronchiolitis radiologically, which were predominant in WHO classified severe pneumonia (p<0.05). Wheeze was present in case of hyperinflation of lung in 78(83.8%), increased translucency in 67(72%) and increased interstitial marking in 70(75.2%) patients among radiological bronchiolitis (n=90). From above results we can concluded that Bronchiolitis was predominant among WHO guideline classified severe pneumonia.
