Clinical and pathological variability of infection by enterohaemorrhagic (Vero cytotoxin producing) Escherichia coli.

The clinical and pathological features of five sporadic cases of enteric infection caused by Escherichia coli O157 (enterohaemorrhagic or Vero cytotoxin-producing E coli showed a range of features. These included one case with pseudomembranous colitis, one with an acute exacerbation of ulcerative colitis, and three with enterocolitis. Diagnostic difficulties encountered initially in four of the five cases were finally resolved by correlating the results of microbiological with histopathological investigations. In view of the heterogeneity of clinical and histological signs and symptoms, it is concluded that all patients with abdominal pain and diarrhoea or rectal bleeding should have early microbiological investigation.

Outcome of very-low-birth-weight (< 1,500 grams) infants born to mothers with diabetes.

Premature delivery is common in pregnancies complicated by maternal diabetes. However, the outcome of very-low-birth-weight infants (VLBWI) born to mothers with diabetes is not known. Employing a matched double-cohort design, we investigated the influence of maternal diabetes on the outcome of VLBWI born in Winnipeg from 1988 to 1994. We compared mortality rates and early and late morbidity rates in VLBWI born to mothers with diabetes mellitus (DM) (cases, n = 43, 23 with gestational DM and 20 with pregestational DM) and without DM (controls, n = 539). Controls were matched for gestational age (GA), sex, and the year of birth. All subjects were enrolled in the Newborn Follow-Up Program. Relative risks and 95% confidence limits were calculated for each variable and Chi 2 analysis, Student t-test, and Mann-Whitney test were used as appropriate for analysis. Diabetes mellitus control was assessed by conventional criteria. There were no differences between cases and controls in mode of delivery, birth weight (mean +/- SD, 1,160 +/- 25 g vs 1,110 +/- 26 g), GA (29 +/- 2.8 wk vs 29 +/- 2.4 wk), smallness for gestational age (35% vs 30%), head circumference (26.5 +/- 1.9 vs 26.2 +/- 2.2 cm), length (38.8 +/- 2.8 vs 37.5 +/- 3.7 cm), Apgar score < 4 at 1 min (42% vs 40%) and < 7 at 5 min (37% vs 42%). Incidence of hyaline membrane disease (60% vs 71%), bronchopulmonary dysplasia (33% vs 31%), patent ductus arteriosus (30% vs 43%), necrotizing enterocolitis (12% vs 12%), sepsis (23% vs 25%), acute renal failure (9% vs 10%), intraventricular hemorrhage--all grades (74% vs 64%), retinopathy of prematurity--all stages (30% vs 26%), median days on ventilator (4 vs 4 days), and median days on supplemental oxygen (46 vs 42 days) were similar in both groups (p = NS, 95% confidence limits included 1 for all of these variables). There was no significant difference in mortality (21% vs 15%) or the incidence of major congenital anomalies. Weight, head circumference, and length at 6, 12, and 18 months were similar in both groups. There were no group differences in developmental quotients, prevalence of neurodevelopmental impairments, respiratory morbidity, or number of hospitalizations up to the last follow-up (18 months). Our data suggest that with contemporary perinatal care there is no significant increase in mortality rates or early and late morbidity rates between VLBWI born to mothers with DM and VLBWI of nondiabetic mothers. It seems that with reasonable diabetic control, prematurity rather than the diabetic state determines the neonatal outcome, and this knowledge can be useful in parental counselling.

Autopsy findings in bone marrow transplantation.

Autopsies were performed on 2 patients with aplastic anaemia and 7 with acute leukaemia dying after bone marrow transplantation. Neutropenic enterocolitis was found in 2 of the 3 early deaths occurring before marrow engraftment and was related to radiation or cytotoxic drug damage to the bowel mucosa in the presence of profound neutropenia, allowing infection by bowel organisms. Cytomegaloviral infection was universal in engrafted patients. One had cytomegaloviral (CMV) pneumonia, one CMV hepatitis and enteritis and one CMV enteritis. Three patients had occasional CMV inclusions in various organs without obvious harmful effects. One nonengrafted patient also had CMV pneumonia. Graft versus host disease (GVHD) was a significant finding in 4 engrafted patients. This was difficult to separate histologically from the effects of CMV in the bowel, but easier in liver and skin. The skin changes of GVHD were the most easily interpretable. Interstitial pneumonia was due to CMV in one nonengrafted and one engrafted patients and had no obvious infective cause in 2 engrafted patients. The presence of bizarre epithelial cells in the lungs of these patients suggested an aetiological role for radiation or cytotoxic drugs. Modification of the conditioning regimen may reduce tissue damage and lessen many of these side-effects.

[Successful treatment of myeloid/natural killer cell precursor acute leukemia with allogeneic peripheral blood stem cell transplantation].

We report a case of myeloid/NK cell precursor acute leukemia, which was successfully treated with allogeneic peripheral blood stem cell transplantation (allo PBSCT). A 31-year-old woman was admitted to our hospital with general fatigue, anorexia and leukocytosis. Bone marrow aspiration showed infiltration of many atypical blasts. She was diagnosed as having myeloid/NK cell precursor acute leukemia by morphological and immunohistochemical analysis. Complete remission was achieved by induction chemotherapy, but as myeloid/NK cell precursor acute leukemia is reported to have an extremely poor prognosis due to frequent relapse, the patient underwent allo PBSCT from her HLA-identical father, together with a myeloablative conditioning regimen. She suffered several transplantation-related complications including acute graft versus host disease (grade II) and ischemic enterocolitis associated with thrombotic microangiopathy, but these were overcome by supportive therapy. She was discharged on day 168 after allo PBSCT, and so far there has been no evidence of relapse during a follow-up period of 15 months.

[Evolution of the methods of peritonization of the vermiform process stump in acute destructive appendicitis complicated by typhlitis].

A comparative assessment of effectiveness of various non-traditional and non-typical variants of appendectomy was made with using non-standard (non-classical) methods of treatment and peritonization of the vermiform stump developed by different authors for destructive forms of acute appendicitis complicated by inflammatory infiltration of the blind gut cupola and typhlitis. An analysis of results of using the proposed non-typical technical methods and techniques as well as an assessment of the authors' technique used in 43 patients suggests that the above variants of peritonization of the vermiform process stump should not be considered as competing. Each of the methods can be successfully used depending on the concrete clinical situations and for the corresponding indications as the most optimal method of choice or as an alternative of the classical variant of appendectomy in patients with acute destructive appendicitis complicated by inflammatory infiltration of the blind gut cupola and typhlitis.

[Bacterial complications in acute hepatic failure in patients with hepatitis B].

With virus hepatitis B (VHB) associated with acute hepatic insufficiency, precoma and coma, one third of the patients develop bacterial purulent inflammatory complications involving mainly biliary system and intestine. Attendant bacterial complications promoted rapid progression of hepatic coma seen commonly on day 1-10 of the disease. The diagnosis in relevant patients recognizing bacterial complications clinically should be based on alterations in the liver size, the presence of fever, elevated body temperature, relatively low decrease of prothrombin index and fibrinogen against leukocytosis with stab neutrophil shift. These symptoms call for introduction of antibacterial drugs.

[Clinico-immunologic characteristics of acute intestinal diseases caused by Pseudomonas aeruginosa].

The examination of 118 intestinal disorders caused by Ps. aeruginosa in patients aged 18-60 provided evidence on its higher incidence in summer and autumn, acute onset, short latent period, systemic toxic and dyspeptic syndromes. Intestinal picture involved syndromes of gastroenteritis, gastroenterocolitis, in the severe course--of hemocolitis. Grave forms of Ps. aeruginosa infection entail drastic changes in immune status registered till the discharge from hospital: T-lymphopenia, high CIC levels, a lower immunoregulatory index.

[Hirschsprung's disease in newborns].

The authors examined and treated 52 newborn babies and infants with Hirschsprung's disease. The total form was encountered in 25%, the subtotal in 23.1%, the rectosigmoid in 36.5%, the rectal in 9.6%, and the supraanal in 5.8% of cases. The clinical picture was characterized by retention of meconium (94.2%), regurgitation or vomiting (75%), abdominal distention (100%). Irrigography with calculation of the rectosigmoid ratio was conducted in 35 children, histochemical examination in 46, and histological examination in 38 children. Twenty-four (68.5%) children had the third phase of disturbed proportion of the intestinal bacteria with clinical manifestations of enterocolitis. Emergency decompression of the intestine for low acute intestinal obstruction was carried out in 27 newborn babies. Twenty children were subjected to radical surgery in the first 2-4 months of life. The choice of the operative method was guided by the form of the disease and the length of the aganglionic zone.

Combination of "patch, drain, and wait" and home total parenteral nutrition for midgut volvulus with massive ischemia/necrosis

The successful use of a combination of "patch, drain, and wait" (PDW) and home total parenteral nutrition (TPN) in the management of a case of acute, catastrophic midgut volvulus in a 2-year-11-month-old boy with near-total ischemia/necrosis of his small intestine is reported. The PDW approach to the highly effective management of acute midgut ischemia/necrosis in infancy and childhood (necrotizing enterocolitis and midgut volvulus) involves maximum gut salvage by avoidance of resection, stoma formation, or both through the use of extensive peritoneal cavity drainage by Penrose drains, TPN, and broad-spectrum antibiotics. The extensive peritoneal drainage fosters capture of enteric fistulas with the formation of enterostomies at drain exit sites, while adhesions and ischemia/inflammation-induced hypervascular obliteration of the peritoneal cavity diminish the potential for peritonitis (no peritoneal cavity, no peritonitis) and facilitate impressive salvage of seemingly hopelessly lost ischemic/necrotic gut (a simulation of the in utero ischemic gut process leading to atresias and some varying, but generally mild, gut loss) while simultaneously contributing to the resorption of absolutely non-salvageable gut and the creation of a remarkably clean and adhesion-free peritoneal cavity resembling that of a newborn infant with midgut intestinal atresia.

Plasma concentration of intestinal- and liver-FABP in neonates suffering from necrotizing enterocolitis and in healthy preterm neonates.

Both early diagnostic and prognostic assessment of the acute abdomen in preterm infants are hampered by the lack of a sensitive and specific parameter for intestinal injury. In this prospective clinical study we wanted to estimate the value of intestinal (I-) and liver (L-) fatty acid binding protein (FABP) in diagnosing necrotizing enterocolitis (NEC). Using highly sensitive and specific sandwich ELISAs which employ recombinant human I- and L-FABP as standard proteins (limit of detection 0.1 ng/ml plasma), the L-FABP concentration (median 7.6 ng/ml) was determined to be about 3 fold that of I-FABP (median 2.52 ng/ml) in plasma of healthy preterm infants. I- and L-FABP concentrations significantly increased with birth weight (1.6 and 5.0 ng/ ml per kg, respectively). At onset of symptoms, I-FABP concentration was significantly higher in infants who later developed severe NEC compared to healthy infants and those, whose illness remained confined to stage I or II. L-FABP was significantly elevated compared to the control group at onset of symptoms regardless of the further course of NEC. In conclusion, I-FABP appears to be a specific parameter for early detection of intestinal injury leading to severe NEC stage III. L-FABP, however, is a promising sensitive marker even for stage I of NEC.
