Hemophagocytosis in visceral leishmaniasis is rare and usually mild. However, presentation as hemophagocytic syndrome is exceptionally rare. We report the case of a 28 years man who presented with fever, hepatosplenomegaly, pancytopenia, reactive histiocytes and severe hemophagocytosis. Subsequent investigations revealed he had Leishmania donovani infection.

Primary neuroendocrine carcinoma of the gall bladder is rare. We report a 70-year-old woman with a gall bladder mass and liver metastases; fine-needle aspiration cytology from these revealed neuroendocrine carcinoma. There was no evidence of any other primary site. The patient was treated symptomatically; she died within a month of discharge from hospital.

In view of the limitations in the accurate visual assessment of jaundice and its potential role as a predictive vector for serious neurologic sequelae, we propose that a universal screening of bilirubin be considered concurrent to the routine pre-discharge metabolic screening. Universal bilirubin screening in the term and near-term newborns when plotted on "Hour-specific Bilirubin Nomogram" in lieu of the usual "day-specific" value will predict the high-risk and the low-risk groups and facilitate cost-effective and individualized follow-up of those babies at risk. A percentile based bilirubin nomogram for the first week of age was constructed from hour-specific pre- and post-discharge bilirubin values of 2840 healthy term and near-term babies. The accuracy of the pre-discharge bilirubin values was determined as a predictive vector. Pre-discharge (18-72 hours age), 6.1% of the study population had bilirubin values in the high-risk zone (> 95th percentile). Of these, 39.5% remained in that zone (likelihood ratio ¿LR¿ = 14.08). Pre-discharge, 32.1% of the study population had bilirubin values in the intermediate risk zone (40-75th percentiles). In a clinically significant minority of these babies (6.4%), the post-discharge values moved to the high-risk zone (L-R = 3.2 for the move from the upper-intermediate zone and 0.48 from the lower-intermediate zone). In the remainder 61.8% of the population who were identified to be at low risk, there was no measurable risk for significant hyperbilirubinemia (L-R = 0). The bilirubin nomogram can predict which infant is at high, intermediate, and low risk for subsequent excessive hyperbilirubinemia and allows for the individualized follow-up of these high-risk babies with particular attention to those who may need evaluation and intervention. Whereas, identification of the low risk group allows for a less intense bilirubin follow-up and in whom a visual check by an experienced care-provider may suffice.

Presentation of abdominal tuberculosis with portal hypertension is rare. We report a 25-year-old man with portal hypertension due to compression of the portal vein by tuberculous lymph nodes at the hepatic hilum. After antitubercular therapy, features of portal hypertension disappeared as the nodes regressed.

This article reviews the current trends in the evaluation and management of bacterial infection involving the uterus, placenta, membranes, amniotic fluid, and fetus occurring near the time of birth. The discussion includes information regarding risk, incidence, pathophysiology, bedside diagnosis, interventional options including antibiotics, corticosteroids, fetal monitoring, and delivery, and possible preventive measures which affect the outcome. The adequate evaluation and management of perinatal infection requires a team approach with obstetricians and pediatricians. Clinical screening is useful in developing the diagnosis, but amniotic fluid evaluation remains the proposed gold standard. The role of cytokines is becoming increasingly important, as is seen in the association of IL-6 with positive amniotic fluid cultures and periventricular leukomalacia. Prompt recognition and management of the pregnancy affected by infection can improve perinatal outcomes. A management protocol is presented to help structure the approach to suspected infection. Premature delivery due to perinatal infection may be preventable.

Short-term inhaled dexamethasone therapy was evaluated in a double blind placebo controlled trial in 36 ventilator dependent preterm neonates (BW < 1500 gm, postnatal age > 7 days) who were at risk for bronchopulmonary dysplasia. Pulmonary and systemic effects were compared at early (day 3), late (7-10 days) and post (14 days after initiation) phases of therapy. Airflow mechanics improved as demonstrated by a net 101% improvement in pulmonary resistance (a decrease from 139 to 101 cm H2O/L/s in the dexamethasone treated infants as compared to an increase from 153 to 267 cmH2O/L/s in the placebo treated infants during the early phase of therapy); this was associated with a 45% increase in inspiratory airflow (1.29 +/- 0.43 to 1.87 +/- 0.978 L/min; p < 0.01), and 37% increase in expiratory airflow. These changes resulted in a significant reduction in the work of breathing such that the mean tidal driving pressure significantly decreased from 13.6 cmH2O to 9.4 cm H2O with inhaled steroid administration. Though the brief duration of therapy did not result in cessation of ventilatory support, the level of support was significantly reduced (decreased values of oxygen supplementation, mean airway pressure and oxygenation index and increased ventilatory efficiency index). The inhaled dexamethasone therapy was also associated with systemic absorption of the drug as evidenced by transient but apparently reversible reduction in serum cortisol levels. No systemic side effects of hypertension, hyperglycemia or nosocomial sepsis were observed. These data demonstrate beneficial effects of short-term inhaled dexamethasone on the resistive airflow properties of preterm infants at risk for BPD and may provide adjunctive means to facilitate weaning in the ventilator dependent neonates.
