Tranexamic acid in prevention of postpartum hemorrhage in elective cesarean section

Background: Postpartum hemorrhage is a common and occasionally life-threatening complication of labor. Cesarean section is associated with more blood loss in compared to vaginal delivery. Despite, there is a trend for increasing cesarean section rates in both developed and developing countries thereby increasing the risk of morbidity and mortality, especially among anemic women. The objective of this study was to evaluate the effect of preoperative administration of intravenous Tranexamic acid on blood loss during and after elective cesarean section.Methods: This was a prospective, randomized controlled study with 160 eligible pregnant women of 37 or more period of gestation. They were all planned for elective cesarean section and were randomized into two groups either to receive 10ml (1gm) of Tranexamic acid intravenously or 10ml of normal saline. Blood loss was measured during and for 24 hours after operation.Results: The mean estimated blood loss was significantly lower in women treated with Tranexamic acid compared with women in the placebo group (392.13 ml±10.06 vs 498.69 ml±15.87, respectively; p<0.001). The mean difference in pre-operative and post-operative hemoglobin levels was statistically significant in the Tranexamic acid group than in the control group (0.31±0.18 vs 0.79±0.23, respectively; p<0.001).Conclusions: Pre-operative use of Tranexamic acid is associated with reduced blood loss during and after elective cesarean section. In a developing country like ours where postpartum hemorrhage is a major threat to the life of the mothers, it seems to be a promising option.

Assessment of control of bronchial asthma in children using Childhood Asthma Control Test.

Background. The use of Childhood Asthma Control Test (C-ACT) has been advised for monitoring asthma control by the Global Initiative for Asthma (GINA) guidelines. Objective. To validate the tool C-ACT for the assessment of control of asthma and to examine the correlation between C-ACT score and lung function assessed by forced expiratory volume in one second (FEV1). Methods. This was a prospective observational study conducted between January 2010 to January 2011. Children diagnosed to have bronchial asthma and aged 5 to 14 years, were enrolled in the study. Asthma severity and control status were classified according to the National Asthma Education and Prevention Programme (NAEPP) and GINA guidelines, respectively. Patients were followed-up at three and six months and C-ACT and spirometric measurements were obtained. Results. Significant positive correlations were found between C-ACT score and FEV1 at enrollment (r=0.772) (p<0.001), three months (r=0.815) (p<0.001) and at six months follow-up (r=0.908) (p<0.001). Baseline C-ACT score was useful for predicting the levels of control of asthma upto three months (0.004), but not at six months follow-up (0.787). A cut-off C-ACT value of >19 had a sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) 98.5%, 89.1%, 94.9%, 96.6%, 0.717, respectively for the control of asthma. Conclusion. C-ACT is a simple and feasible tool to assess and predict the levels of control in children with bronchial asthma upto three months.

Clinical and etiological profile of acute febrile encephalopathy in eastern Nepal.

Objective. To investigate the clinical and etiological profile of acute febrile encephalopathy in children presenting to a tertiary care referral center of Eastern Nepal. Methods. 107 children (aged 1 month to 14 yr) presenting to the emergency with fever (> 380 C) of less than 2 wk duration with altered sensorium with/ or without seizure were prospectively investigated for etiological cause. The investigations included blood and CSF counts, blood and CSF cultures, peripheral smear and serology for malarial parasite, and serology for Japanese encephalitis (JE) virus. Other investigations included EEG and CT or MRI wherever indicated. Results. The most common presenting complaints apart from fever and altered sensorium were headache and vomiting. Convulsions, neck rigidity, hypertonia, brisk deep tendon reflexes, extensor plantar response and focal neurological deficits were seen in 50%, 57%, 22.4%, 28%, 39.3% and 9.3% of the subjects, respectively. The diagnoses based on clinical presentation and laboratory findings were pyogenic meningitis in 45 (42%), non JE viral encephalitis in 26 (25%), JE in 19 (18%), cerebral malaria in 8 (7%), herpes encephalitis and tubercular meningitis in 4 (4%) each, and typhoid encephalopathy in 1 case. Conclusion. Pyogenic meningitis and viral encephalitis including JE are the most common causes of acute presentation with fever and encephalopathy. Preventive strategies must be directed keeping these causes in mind.

Systemic lupus erythematosus in childhood--a review of 11 patients at a single center in eastern Nepal.

We retrospectively evaluated the clinico-laboratory features of 11 children and adolescents with Systemic Lupus Erythematosus between the period of 2001 and 2006. All of them (100.0%) had renal involvement at the first visit in the hospital. Female to male ratio was 10:1. Skin and or mucosal involvement (90.9%), periorbital puffiness and or pedal edema (81.8%), fever (72.7%), hypertension (72.7%), and reticuloendothelial involvement (72.7%), were the commonest presentations. All patients had anemia (8.6 +/- 1.5 gm/dl), raised ESR (46.7 +/- 9.4 mm in first hour), proteinuria, and in disease activity as evident by raised ESR and positive anti-dsDNA antibody at the first visit. The mean duration of disease was 7.6 months and the average duration of disease activity was 63.18 days. Renal biopsy was performed in 8 patients: class IV lupus nephritis in 4 patients (50.0%), class II in 2 patients (25.0%), class III and V in patient (12.5%) each. Nephrotic range proteinuria and hypertension was observed in all patients of class IV and V of lupus nephritis. Class II and III lupus nephritis patients' were normotensive and had non-nephrotic range proteinuria. Three out of 11 patients (27.2%) expired. The commonest primary determinant of mortality was uncontrolled disease activity in 2 patients (66.6%). The third one had infection and developed disseminated intravascular coagulation. The mean duration of disease activity in patients who died (mean 30 days) was statistically lower than the survival group (75.6 days) (p < 0.01). Renal involvement during first visit and mortality could be attributed by late referrals and diagnosis at hospital.
