Effect Of TXA On Intraoperative Blood Loss In Mandibular Fracture Surgeries A Prospective, Double Blinded Randomized Clinical Trial

Background:The aim of this doubleblind prospective study was to determine whether administering 1 gm Tranexamic Acid (TXA) would the intraoperative blood loss during the Open Reduction and Internal Fixation (ORIF) surgery of mandibular fracture via the intraoral approach operated under local anesthesia (LA).Material And Methods:20 patients who underwent ORIF surgery ofmandibular fractures under LA were randomly allocated to two groups. Study group was administered 1 gm TXA diluted in a 500 ml Ringer Lactate solution one hour before thesurgery. Control group did not receive any such IV infusion. All the surgeries were performed by the same surgeon.Result:Mean difference in Intraoperative blood loss between the two groups was found out to be statistically insignificant. Effect of age, gender or site of fracture was also found out to be insignificant. Conclusion:There is not much effect of TXA on intraoperative blood loss during ORIF of a mandibular fracture via the intraoral approach. Even without tranexamic, if area is infiltrated with adrenaline, proper flap reflection and tissue handling technique is used, and vital structures avoided; blood loss will be minimal.

Subclinical hypovitaminosis D among exclusively breastfed young infants.

OBJECTIVE: To determine Vitamin D status of mother-newborn diads at birth and of their exclusively breastfed (EBF) infants at 3 months. DESIGN: Longitudinal study. METHODS: Exclusively breastfed infants born at term with birth weight > 2.5 kg to normal, healthy mothers followed till 3 months. Serum calcium, phosphorous, heat labile alkaline phosphatase (HLAP) and 25(OH)D estimated in 42 mother / cord blood diads and in 35 (EBF) infants followed up at 3 months. Twenty five (OH)D < 15 ng/mL was considered low and 15 to 25 ng/mL low to normal. RESULTS: Ca, P, HLAP were significantly higher in cord blood (P < 0.001) but mean 25 (OH)D, 19.36 ng/mL was comparable to maternal level of 22.9 ng/mL (r = 0.82, P < 0.001). At 3 months only HLAP was significantly higher compared to cord blood. Higher 25 (OH)D at 3 months correlated with higher 25 (OH)D values in cord blood (r = +0.616, P < 0.001) as well as higher antenatal maternal levels (r = + 0.552, P < 0.001). Serum 25 (OH)D values < 25 ng/mL was observed in 50 % mothers, 62 % cord blood specimens and 80 % infants at 3 months. CONCLUSIONS: Subnormal maternal vitamin D status is associated with vitamin D deficiency in newborns and persists in exclusively breastfed infants.

Seroepidemiology of hepatitis A infection in India: changing pattern.

OBJECTIVE: Recent changes in the epidemiology of hepatitis A virus (HAV) infection and the availability of effective vaccines have renewed interest in this infection. We determined the age-related prevalence of anti-HAV antibodies in India and looked for differences by known risk factors for HAV infection. METHODS: In this prospective study, serum samples obtained from 1612 subjects aged 1 to 60 at six centers in five cities (Calcutta, Cochin, Indore, Jaipur and Patna) during the period February to August 1998 were tested for anti-HAV antibodies. Demographic and socio-economic information was obtained by questionnaire. RESULTS: The overall seroprevalence rate was 65.9%, varying from 26.2% to 85.3% in various cities; there was no difference between males and females. Seropositivity increased with age from 52.2% in the 1-5 year age group to 80.8% in those aged 16 years or more. Seroprevalence rates were significantly lower in those aged 1-5 years compared with other age groups (p<0.0001). There was no difference in seroprevalence between those with monthly family income <Rs 5000 and >Rs 5001. Multivariate analysis showed that anti-HAV seroprevalence varied significantly by source of water supply, being highest when the supply was municipal. CONCLUSION: Our results indicate an epidemiological pattern of intermediate endemicity. This finding has public health implications as it indicates that a significant proportion of the Indian adolescent and adult population is at risk of HAV infection.
