Diagnosis and treatment of an anuric premature infant with severe respiratory compromise and a normal renal ultrasound (US), is a difficult task that requires a multidisciplinary approach. A 29-week gestation premature male infant, born after 5 weeks of worsening oligohydramnios, was ventilated for respiratory distress and remained anuric. Intensive clinical investigations and pediatric nephrology consultation that predicted very poor prognosis were followed by progressive renal failure, electrolyte imbalance, respiratory failure, ventricular arrhythmia, and finally cardiac arrest and death on day 5. In view of the predicted poor outcome, and after discussion with the parents, a decision was made not to start peritoneal dialysis (PD), and to offer only palliative therapy, with comfort care alone. Pre and postnatal diagnosis lead, in this case, to an ethical challenge that focuses on the question of futility.

Bilateral axillary arterial cannulation for selective cerebral perfusion might minimize cerebral embolic complications during surgery on the ascending aorta and aortic arch. From March 2002 through February 2004, bilateral axillary arterial perfusion was applied in 12 consecutive patients (mean age, 61.3 years). Operative procedures were total arch replacement in 8 patients, hemiarch replacement in 1, and ascending aorta replacement in 3. Antegrade selective cerebral perfusion was established through vascular grafts anastomosed to the bilateral axillary arteries and a perfusion catheter placed directly into the left carotid artery. Bilateral axillary arterial perfusion through the grafts was successful in all patients. There were no early or late deaths and no incidence of neurologic deficit. There were no complications related to cannulation of the axillary arteries. Bleeding, temporary renal failure, acute respiratory distress syndrome, and graft infection occurred in one patient each; all recovered from these complications. Bilateral axillary arterial perfusion is feasible and effective for brain protection during surgery on the ascending aorta and aortic arch.

A young homosexual male presented to the emergency department with respiratory distress, oropharyngeal candidiasis, hypoxaemia, and renal failure. Pneumocystis carinii pneumonia was considered to be the likely diagnosis - until 24 h later when the patient divulged the true history of paraquat ingestion some 5 days previously. Ingestion of corrosives should be considered in patients with oropharyngeal candidiasis and pneumonic symptoms, especially in the presence of renal failure as an alternative to HIV infection.

Brain death is associated with complex hemodynamic, endocrine, and metabolic dysfunction that can lead to major complications with the potential donor. Untreated, this can progress to cardiovascular collapse with loss of valuable organs for transplantation. We hypothesized that brain death-related complications would have no effect on the number of organs donated if an aggressive donor management protocol was in place. We identified all successful organ donations between January 2000 and December 2003 and evaluated them for brain death-associated complications (defined as vasopressor requirement, coagulopathy, diabetes insipidus, cardiac ischemia, lactic acidosis, renal failure, and acute respiratory distress syndrome) and donated organs per donor. Sixty-nine organ donors were identified. Complications identified were as follows: intravenous vasopressor requirement in 97.1 per cent, coagulopathy in 55.1 per cent, thrombocytopenia in 53.6 per cent, diabetes insipidus in 46.4 per cent, cardiac ischemia in 30.4 per cent, lactic acidosis in 24.6 per cent, renal failure in 20.3 per cent, and acute respiratory distress syndrome in 13 per cent. There was no significant effect of complications on the average number of organs harvested, with the exception of an increase in organs harvested in the presence of diabetes insipidus. With the implementation of an aggressive organ donor management protocol, these complications can be effectively managed with no impact on the number of organs harvested for transplant.

The aim of this tertiary hospital-based cohort study was to determine and compare perinatal outcome and neonatal morbidities of pregnancies with twin-twin transfusion syndrome (TTTS) before and after the introduction of a treatment program with laser ablation of placental communicating vessels. Twenty-seven pregnancies with Stage II-IV TTTS treated with amnioreduction were identified (amnioreduction group). The data were compared with that obtained from the first 31 pregnancies with Stage II-IV TTTS managed with laser ablation of placental communicating vessels (laser group). Comparisons were made for perinatal survival and neonatal morbidities including abnormalities on brain imaging. The median gestation at therapy was similar between the two groups (20 vs. 21 weeks, p = .24), while the median gestation at delivery was significantly greater in the laser treated group (34 vs. 28 weeks, p = .002). The perinatal survival rate was higher in the laser group (77.4% vs. 59.3%, p = .03). Neonatal morbidities including acute respiratory distress, chronic lung disease, requirement for ventilatory assistance, patent ductus arteriosus, hypotension, and oliguric renal failure had a lower incidence in the laser group. On brain imaging, ischemic brain injury was seen in 12% of the amnioreduction group and none of the laser group of infants (p = .01). In conclusion, these findings indicate that perinatal outcomes are improved with less neonatal morbidity for monochorionic pregnancies with severe TTTS treated by laser ablation of communicating placental vessels when compared to treatment by amnioreduction.

Six healthy young male volunteers at a contract research organization were enrolled in the first phase 1 clinical trial of TGN1412, a novel superagonist anti-CD28 monoclonal antibody that directly stimulates T cells. Within 90 minutes after receiving a single intravenous dose of the drug, all six volunteers had a systemic inflammatory response characterized by a rapid induction of proinflammatory cytokines and accompanied by headache, myalgias, nausea, diarrhea, erythema, vasodilatation, and hypotension. Within 12 to 16 hours after infusion, they became critically ill, with pulmonary infiltrates and lung injury, renal failure, and disseminated intravascular coagulation. Severe and unexpected depletion of lymphocytes and monocytes occurred within 24 hours after infusion. All six patients were transferred to the care of the authors at an intensive care unit at a public hospital, where they received intensive cardiopulmonary support (including dialysis), high-dose methylprednisolone, and an anti-interleukin-2 receptor antagonist antibody. Prolonged cardiovascular shock and acute respiratory distress syndrome developed in two patients, who required intensive organ support for 8 and 16 days. Despite evidence of the multiple cytokine-release syndrome, all six patients survived. Documentation of the clinical course occurring over the 30 days after infusion offers insight into the systemic inflammatory response syndrome in the absence of contaminating pathogens, endotoxin, or underlying disease.

Mesenteric injuries after blunt abdominal trauma are infrequent and difficult to diagnose. We investigated whether a delay in diagnosis of more than 6 hours had a significant impact on morbidity, mortality, and length of stay at our Level I trauma center. A retrospective chart review spanning the period from January 1995 to September 2005 identified 85 patients with laparotomy-confirmed mesenteric injuries, 81 of whom survived to hospital discharge. Nineteen (23%) of the 81 patients had a delay in diagnosis of greater than 6 hours. After controlling for identified confounders, we found that the delayed diagnosis group experienced 30 per cent longer hospital stays (P = 0.03), 55 per cent longer intensive care unit stays (P = 0.006), and 38 per cent longer duration of mechanical ventilation (P = 0.05). Patients in the delayed group also had significantly higher odds of developing acute respiratory distress syndrome, as well as trends toward higher odds of wound infection, pneumonia, multiple organ dysfunction syndrome, abdominal compartment syndrome, renal failure, and ileus. No significant difference in mortality was observed among all 85 patients (P = 0.67). Thus, in contradiction to some previous studies, our review indicates that a delay in the diagnosis of mesenteric injuries results in significantly increased morbidity and hospital and intensive care unit lengths of stay.

Cerebral malaria is the most common cause of non-traumatic encephalopathy in the world. The mainstay of therapy is either quinine or artemisinin, both of which are effective antimalarials. The clinical picture of cerebral malaria may persist or even become worse in spite of the clearance of parasites from blood. The death rate is unacceptably high even with effective antimalarials in tertiary care hospitals. The mortality increases in presence of multi organ failure (renal failure, jaundice, respiratory distress, severe anaemia, lactic acidosis, etc.). The pathogenesis of cerebral malaria is multifactorial and includes clogging, sequestration, rosette formation, release of cytokines, cerebral oedema, increased intracranial hypertension, etc. Attempts are made to use adjuvant therapy which will act through alternate mechanisms and address one or more of the pathogenetic processes. In this review, we have discussed the role of corticosteroids, pentoxifylline, desferrioxamine, mannitol and newer agents in the treatment of cerebral malaria. Though the literature on adjuvant therapy in cerebral malaria is large enough, there are a number of shortcomings in the clinical trials, many being open and non randomized or of very small sample size. Further research is of utmost importance through large multicentric, double-blind controlled trials to show the efficacy of any of these drugs.

Severe malaria is invariably caused by Plasmodium falciparum. In India, both adults and children are affected by severe malaria. However, children are more prone for developing anemia and convulsions as manifestations of severe malaria, while acute renal failure and jaundice are more common among adults. Pregnant women are vulnerable to hypoglycemia, anemia and pulmonary complications. The case-fatality rate due to severe malaria is 10-15% in spite of therapy but it increases in the presence of renal failure or respiratory distress (pulmonary edema or ARDS). Of late, multi-organ failure and high mortality figures are being reported increasingly from different parts of India. Early diagnosis and prompt treatment will reduce the mortality due to malaria. Cerebral malaria should always be suspected in a patient with altered sensorium in a malaria-endemic area. However, other causes of unconsciousness such as encephalitis, meningitis or hepatic coma should also be excluded. Parenteral quinine is the mainstay of therapy. A recent multi-centric study has demonstrated the efficacy of intravenous artesunate in reducing the mortality by 30%. The usefulness of adjunct therapy is still controversial.

A newly developed rapid immunoassay method for plasma soluble E-selectin (sES) was examined to determine whether it can predict the development of acute respiratory distress syndrome (ARDS) in critically ill patients with systemic inflammatory response syndrome (SIRS). Plasma levels of sES were measured on admission (day 1) to the emergency unit. Development of various types of organ failures including ARDS was compared in the first 5 days of admission (from day 1 to day 5) between patients with normal plasma levels of sES and those with elevated plasma levels of sES. Plasma levels of sES were determined using a newly developed latex agglutination method that takes 20 min to obtain the test results. The normal range of the plasma sES level was 4.8-29.7 ng/mL with this method. Among the patients examined, 22 patients showed elevated sES levels (D(A)E group) and 28 showed normal sES levels (D(A)N group). Development of ARDS was significantly higher in the D(A)E group (15/22, 68.2%) than in the D(A)N group (4/28, 14.3%) (P < 0.001) and that of cardiovascular system failure, renal failure, and coagulation system failure was also significantly higher in the D(A)E group than in the D(A)N group. The mortality rate at 28 days after admission was higher in the D(A)E group (27.3%) than in the D(A)N group (0%) (P < 0.05). Determination of sES levels by this new rapid assay method might be useful for prediction of the development of ARDS in critically ill patients with SIRS, a pathologic condition that has the potential risk for development of multiple organ failure.
