Spectrum of purpura fulminans.

Purpura Fulminans is a severe disorder of acute onset with high morbidity and mortality. It is characterized by DIC with thrombocytopenia, hyofibrinogenemia, hypothrombinemia and anemia. It most often occurs in young with sudden appearance of symmetrical, tender, ecchymotic skin lesions usually involving the lower extremities. An infectious and noninfectious etiology has been proposed. Early recognition and early therapy with appropriate antibiotics and heparin is known to limit both morbidity and mortality. This article reports 5 cases of Purpura Fulminans treated at our centre with review of etiology, pathogenesis, clinical features and treatment.

Fanconi's anemia in monozygotic twins.

Fanconi's anemia is one of the inherited causes of bone marrow failure. It is inherited in autosomal recessive fashion. It presents as aplastic anemia usually at the age of 7-8 yr. Leukemias and solid tumours are complications in those who manage to survive beyond two decades. Though it has been seen in siblings, reports in monozygotic twins have been very few.

Immunogenicity and safety of combined diphtheria tetanus whole cell pertussis hepatitis B/ Haemophilus influenzae type b vaccine in Indian infants.

OBJECTIVE: To evaluate the immunogenicity of the Hepatitis B and Haemophilus influenzae type b components and the overall safety and reactogenicity of the DTPw-HBV/Hib vaccine when given as primary vaccination to Indian infants. DESIGN AND METHODS: At 3 centers in India, 225 healthy infants (who had received HBV at birth) received three doses of DTPw-HBV/Hib vaccine at 6, 10 and 14 weeks of age. Serum anti-HBs and anti-PRP antibody levels were measured prior to vaccination and one month post dose 3. Solicited local and general symptoms reported during the 4-day follow-up period and unsolicited adverse event reported during the 30-day follow-up period after each dose were recorded. Serious adverse events were recorded throughout the study. RESULTS: A total of 219 subjects completed the study. 2.7% and 11.5% of all administered doses led to redness and swelling >20 mm, respectively; only 3.6% of doses were followed by severe pain (cried when limb was moved, spontaneously painful) within 4 days after vaccination. Fever exceeding 39.5C was recorded following only one dose in one subject. The percentage of doses followed by severe solicited general symptoms (symptoms that prevented normal activity) did not exceed 0.8%. Two SAEs were reported, neither of which were considered as related to vaccination. One month post-dose 3, all subjects had seroprotective antiPRP antibody concentrations (> or =0.15 microgram/mL) and 98.6% had concentrations > or =1 microgram/mL; 99% were seropositive for antiHBs (concentrations > or = 3 mIU/mL) and 99% were seroprotected (concentrations > or = 10 mIU/mL). CONCLUSION: The combination DTPw-HBV/Hib vaccine is immunogenic (for the antigens tested), safe and well tolerated in Indian infants.

Multicenter randomized placebo controlled trial of therapy with intravenous immunoglobulin in decreasing mortality due to neonatal sepsis.

OBJECTIVE: To determine whether therapy with intravenous immunoglobulin G (IVIG) would decrease mortality in neonatal sepsis. SETTING: Three tertiary care neonatal intensive care units in the city of Bangalore. METHODS: All neonates admitted to the Neonatal Intensive Care Units with the clinical diagnosis of sepsis and having at least C-reactive protein and one other rapid diagnostic criteria positive were enrolled. Neonates with a birth weight of less than 1000 g and those with any major congenital malformation were excluded. The neonates were randomized to receive 1 g/kg of IVIG on three consecutive days or an equivalent amount of placebo. The rest of the treatment including antibiotics and supportive care was as per the treating physician's decision. The main outcome variable was survival. RESULTS: The trial was carried out over a period of 8 months and recruited 58 neonates. Seven neonates who qualified but did not receive either IVIG or placebo were taken into a separate control group, and one baby who received only one dose of IVIG was excluded from the analysis. Twenty-five neonates were enrolled into the IVIG arm and 25 in the placebo arm. The neonates in the therapy and placebo groups were comparable in terms of birth weight (2144+/-675 g vs. 2072+/-682 g), gestation (37.0+/-3.56 vs. 35.8+/-3.52 weeks), sex distribution, duration of stay, and number requiring ventilation. The placebo group had a significantly higher number of babies with positive blood culture. Seven babies in each group died (p>0.05). There was no significant benefit in using IVIG (OR 1.0; 95% CI 0.25-4.07) (p = 0.74). CONCLUSION: In the sample studied therapy with IVIG did not reduce mortality in neonatal sepsis
