From 1982 to 1990, 31 neonates with omphalocele and 54 with gastroschisis were treated at Mackay Memorial Hospital. The overall survival rate for omphalocele was 71%, while it was 85% for gastroschisis. The rate of primary fascial closure for omphalocele (85%) and gastroschisis (87%) was similar. The mortality from omphalocele was almost exclusively due to the presence of serious associated congenital anomalies. Two cases of Cantrell's pentalogy and two of cloacal exstrophy were found. The incidence of major malformation with gastroschisis was 6%. Sepsis, inadequate perioperative resuscitation and prolonged gastrointestinal dysfunction were the major causes of death in gastroschisis. Among survivors, the hospital stay was significantly longer in the silon pouch group than in the primary fascial closure group (71.5 vs 31.3 days for gastroschisis, 41 vs 14 days for omphalocele). Advances in surgical technique, neonatal intensive care and ventilatory support have made primary fascial closure a superior approach without jeopardizing the babies' chance for survival. An improved survival rate and increased primary closure rate are the main features in the treatment of abdominal wall defects in the last decade.

Forty-eight patients with acute renal failure (ARF) who were referred to the Department of Renal Medicine, Singapore General Hospital for acute dialysis between August 1985 and August 1989 were studied retrospectively to identify risk factors associated with ARF that serve as prognostic indicators. There was no difference in the mean age of survivors and non-survivors (49.5 +/- 17.5 years vs 53.5 +/- 18 years, p greater than 0.05). The overall mortality rate was 52%. ARF as a result of surgical complication had a higher mortality rate in comparison to ARF from medical complications (66% vs 50%, p greater than 0.05). Septicaemia was the most common cause of ARF requiring dialysis. Hepatobiliary sepsis was the most frequent cause of septicaemia. Pre-dialysis serum urea and creatinine levels, and the number of dialysis treatments did not affect the outcome. Poor prognostic indicators included oliguria or anuria, fluid overload and coma. Patients tended to have a worse outcome if they had more than three risk factors taken from the following list:-decreased renal perfusion, assisted ventilation, coma, gastrointestinal dysfunction, recent surgery, sepsis, congestive heart failure, hepatobiliary dysfunction, malignancy, diabetes mellitus, chronic renal insufficiency and poor nutritional status. Early referral of patients with septicaemia due in particular to hepatobiliary infection may improve the prognosis.

Fifty (13%) of 375 infants who weighed 1500 g or less at birth had necrotizing enterocolitis (NEC). Haematological changes suggestive of sepsis occurred in 83% and positive bacteriological cultures were found in 38%, the most common organism isolated being Clostridium perfringens. Complications included intestinal perforation in six patients and recurrence of NEC in five, of whom one subsequently developed an intestinal stricture. Five of the eight nursery deaths were secondary to peritonitis and overwhelming sepsis from NEC. In spite of the discontinuation of milk feeds for prolonged periods, satisfactory caloric intake and weight gain were achieved with parenteral nutrition in the survivors. Of the 41 long-term survivors, six (15%) were found to have a disability at 2 years of age, corrected for prematurity, compared with 48 (20%) of 241 very low birthweight survivors from the same study period who did not have NEC. None had evidence of gastrointestinal dysfunction. Six (15%) children remained below the 10th percentile for both weight and height. This study showed that early diagnosis and therapy for NEC in very low birthweight infants were associated with a favourable short- and long-term outcome.

Sedation of critically ill patients is a costly endeavor. Costs of commonly used intensive care unit (ICU) sedatives range from pennies to more than $500 per day. Although the agents account for some of this expense, complications related to the use of these drugs in the ICU produce even greater costs. Prolongation of mechanical ventilation and length of stay are some of the common complications resulting from non-ideal use of these drugs. Sedative agents also impair neurological evaluation in many critically ill patients, which may mask detection of acute delirium resulting from intercurrent illness or intracranial catastrophes and can lead to excessive diagnostic testing. Opiates may result in gastrointestinal dysfunction with resulting malnutrition and perhaps bacterial translocation and sepsis. Neuromuscular blocking agents may cause prolonged paralysis and disability in critically ill patients who receive them. Simple dosing strategies based on pharmacological principles may decrease the incidence of these costly problems.

Although disseminated intravascular coagulation (DIC) has been a well-known disorder for many years, there is lack of sufficient number of clinical trials about incidence, frequency of underlying disorders, and prognosis of DIC in children. The aim of this study was to evaluate the frequency, etiologic factors, and clinical and laboratory findings of DIC and to determine the prognostic factors influencing the mortality in hospitalized pediatric patients. Medical records of 5535 children who were hospitalized were investigated. Sixty-two patients who were diagnosed as acute DIC were enrolled. The frequency of DIC was 1.12%. The underlying etiologic factors were infection in 59 patients (95.2%) and major trauma in 3 patients (4.8%). The frequency of bleeding and thrombosis was 48.8 and 4.8%. Respiratory, cardiovascular, hepatic, renal, neurologic, and gastrointestinal dysfunction was present in 71, 67.7, 35.5, 16.1, 16.1 and 11.3% of patients, respectively. Respiratory and cardiovascular dysfunctions were significantly associated with mortality. Multiorgan dysfunction syndrome (MODS) was present in 85.5% of the patients, and 54.8% of the patients had developed acute respiratory distress syndrome (ARDS). Mortality rate was significantly high in patients with MODS and ARDS. In multivariete logistic regression analysis, only ARDS and cardiovascular dysfunction had predictive and prognostic value on mortality. None of the diagnostic laboratory tests had predictive or prognostic value and the degree of abnormality of these tests did not show any correlation with mortality. In conclusion, DIC is not a rare disorder in hospitalized children, especially in patients with sepsis, and MODS, ARDS, and respiratory and cardiovascular system dysfunctions are poor prognostic factors.

Sepsis is a major disease entity with important clinical implications. Sepsis-induced multiple organ failure is associated with a high mortality rate in humans and is clinically characterized by pulmonary, cardiovascular, renal and gastrointestinal dysfunction. Recently, several studies have demonstrated that sepsis survivors present long-term cognitive impairment, including alterations in memory, attention, concentration and/or global loss of cognitive function. However, the pathogenesis and natural history of septic encephalopathy and cognitive impairment are still poorly known and further understanding of these processes is necessary for the development of effective preventive and therapeutic interventions. This review discusses the clinical presentation and underlying pathophysiology of the encephalopathy and cognitive impairment associated with sepsis.

Traumatic brain injury (TBI) can lead to several physiologic complications including gastrointestinal dysfunction. Specifically, TBI can induce an increase in intestinal permeability, which may lead to bacterial translocation, sepsis, and eventually multi-system organ failure. However, the exact mechanism of increased intestinal permeability following TBI is unknown. We hypothesized that expression of tight junction protein ZO-1 and occludin, responsible for intestinal architectural and functional integrity, will decrease following TBI and increase intestinal permeability. BALB/c mice underwent a weight drop TBI model following anesthesia. Brain injury was confirmed by a neurologic assessment and gross brain pathology. Six hours following injury, FITC-dextran (25 mg 4.4 kDa FITC-dextran) was injected into the intact lumen of the isolated ileum. Intestinal permeability was measured in plasma 30 min following injection, by using spectrophotometry to determine plasma FITC-dextran concentrations. Whole ileum extracts were used to measure expression of tight junction proteins ZO-1 and occludin by Western blot. TBI caused a significant increase in intestinal permeability (110.0 microg/mL +/-22.2) compared to sham animals (29.4 microg/mL +/- 9.7) 6 h after injury (p = 0.016). Expression of ZO-1 was decreased by 49% relative to sham animals (p < 0.02), whereas expression of occludin was decreased by 73% relative to sham animals (p < 0.001). An increase in intestinal permeability corresponds with decreased expression of tight junction proteins ZO-1 and occludin following TBI. Expression of intestinal tight junction proteins may be an important factor in gastrointestinal dysfunction following brain injury.

The role of dysfunction of the gastrointestinal tract in the pathogenesis of multiple organ failure (MOF) complicating the course of critically ill patients has been suspected for more than 40 years. However, several hypotheses have been proposed and sometimes refuted to establish a link. This review summarizes the current knowledge on gastrointestinal physiology and recapitulates existing evidence on the link between gastrointestinal dysfunction and MOF. The gastrointestinal tract has various functions apart from digestion. It produces hormones with local and systemic effects, plays a major role in immunological function, and serves as a barrier against antigens within its lumen. Gastrointestinal dysfunction or gut failure is frequently encountered in critical care patients and is associated with bacterial translocation, which can lead to the development of sepsis, initiation of a cytokine-mediated systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), and death. The aim of this manuscript is to define gut failure, to review physiopathological mechanisms and clinical implications, and, finally, to suggest preventive measures.

The concept of bacterial translocation and gut-origin sepsis as causes of systemic infectious complications and multiple organ deficiency syndrome in surgical and critically ill patients has been a recurring issue over the last decades attracting the scientific interest. Although gastrointestinal dysfunction seemingly arises frequently in intensive care unit patients, it is usually underdiagnosed or underestimated, because the pathophysiology involved is incompletely understood and its exact clinical relevance still remains controversial with an unknown yet probably adverse impact on the patients' outcome. The purpose of this review is to define gut-origin sepsis and related terms, to describe the mechanisms leading to gut-derived complications, and to illustrate the therapeutic options to prevent or limit these untoward processes.

This review describes current understandings about the nature of the very low birth weight infant (VLBW) gut microbiome. VLBW infants often experience disruptive pregnancies and births, and prenatal factors can influence the maturity of the gut and immune system, and disturb microbial balance and succession. Many VLBWs experience rapid vaginal or Caesarean births. After birth these infants often have delays in enteral feeding, and many receive little or no mother's own milk. Furthermore the stressors of neonatal life in the hospital environment, common use of antibiotics, invasive procedures and maternal separation can contribute to dysbiosis. These infants experience gastrointestinal dysfunction, sepsis, transfusions, necrotizing enterocolitis, oxygen toxicity, and other pathophysiological conditions that affect the normal microbiota. The skin is susceptible to dysbiosis, due to its fragility and contact with NICU organisms. Dysbiosis in early life may resolve but little is known about the timing of the development of the signature gut microbiome in VLBWs. Dysbiosis has been associated with a number of physical and behavioral problems, including autism spectrum disorders, allergy and asthma, gastrointestinal disease, obesity, depression, and anxiety. Dysbiosis may be prevented or ameliorated in part by prenatal care, breast milk feeding, skin to skin contact, use of antibiotics only when necessary, and vigilance during infancy and early childhood.
