Septic episodes in thermal injuries are usually hallmarked by a series of physiologic parameters that include tachypnea, prolonged paralytic ileus, hyperthermia or hypothermia, altered mental status, thrombocytopenia, leukocytosis or unexplained leukopenia, acidosis, and hyperglycemia. Recent studies with polycystic kidney disease have clearly indicated that the limulus amebocyte lysate (LAL) assays were predictive of fungal infections in this patient population. Because both bacteria and fungi produce lipopolysaccharide that can be identified with the LAL assay, we randomly assayed sequential sera of 45 patients with major thermal injuries for positivity in the LAL assay, with use of the QCL-1000 kit (BioWhittaker, Walkersville, Md). The average burn size of this patient population was 63.43% total body surface area. The average age of the patient was 6.2 years. The sex distribution included 30 males and 15 females. The infectious agents included gram-positive cocci and gram-negative rods, and 14 patients had concomitant fungal infections. Eighty-five percent of the patients tested were positive for endotoxin, with levels ranging from < 0.1 EU/mL to > 1.0 EU/mL. The predominant organism isolated before or on the date the serum was drawn was Pseudomonas aeruginosa (51%), followed by Klebsiella pneumoniae (15%). The remaining 34% were a variety of Enterobacteriaceae. Of the 14 patients who yielded a fungus, 3 had negative LAL assays. Two patients with an elevated LAL grew only Staphylococcus epidermidis in the bloodstream and the wounds. These data clearly indicate that the LAL assay cannot be relied on as the sole predictor of septic episodes; however, it can be an adjunctive test to confirm sepsis when the other parameters have been considered.

A 2 day old foal was presented with central nervous depression (coma) after moxidectin overdose. Moxidectin belongs to the milbemycin anthelmintics which elicit their working mechanism through a GABA (gamma-aminobutyric acid)-stimulatory mode of action. The foal developed profound hypothermia, bradycardia and hypoventilation. Absence of urine voiding and mild abdominal distension suggested a ruptured bladder, which was confirmed by transabdominal ultrasound and clinical-pathologic parameters. Repeat auscultation of the ventral lung parts and the occurrence of gastric reflux were suggestive of an aspiration pneumonia. The foal underwent surgical bladder repair, however, did succumb due to mixed acidosis and early signs of sepsis postoperatively. The findings in this foal are suggestive for moxidectin overdosing. The GABAergic working mechanism of moxidectin does explain the development of profound central nervous depression and its sequels hypothermia, bradycardia, hypoventilation and paralytic ileus. Dyssynergia was unexpected, however, has to be related to a central nervous problem, rather than a peripheral nervous problem.

Ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia (EDTA-PTCP) is the phenomenon of a spurious low platelet count due to antiplatelet antibodies that cause platelet clumping in blood anticoagulated with EDTA. We describe a case of EDTA-PTCP that appeared transiently with the development of sepsis. A 50-year-old man underwent Bentall's aortic root replacement for acute aortic dissection with aortic insufficiency. Postoperatively the patient suffered paralytic ileus followed by methicillin-resistant Staphylococcus aureus enteritis and septicemia with endotoxemia. EDTA-PTCP appeared with the development of sepsis, and disappeared with its resolution. To avoid incorrect diagnoses and inappropriate treatment, EDTA-PTCP should always be considered as a possible cause of reported low platelet counts, even in patients with sepsis.

Paralytic ileus is defined as an inhibition of propulsive intestinal motility. Postoperative ileus is the most common type, however, also during sepsis and critical illness paralytic ileus is a common finding. The pathogenesis of paralytic ileus is still debated. It is believed to result from the activation of inhibitory neural reflex pathways and activation of inflammatory processes. It is generally accepted that postoperative ileus results from the activation of an inhibitory neural reflex pathway. In our rat model we showed that different degrees of nociceptive stimulation activate different reflex pathways: laparatomy activates an adrenergic inhibitory reflex pathway, whereas manipulation results in additional activation of inhibitory NANC neurons releasing NO and VIP as neurotransmitters. We also demonstrated that blockade of the afferent limb of the reflex pathway by peripheral kappa-opioid agonists or by non-steroidal anti-inflammatory drugs ameliorated postoperative ileus. However, the use of prokinetics lead to disappointing results. In the murine septic model we demonstrated an important role for activation of inducible NO synthase in the endotoxin-induced delay in gastric emptying and small intestinal transit. We hypothesise that activation of the residential macrophages in the gut wall leads to the production of iNOS and other inflammatory mediators. These mediators will attract more inflammatory cells and influence smooth muscle contractility. Next, we provide evidence that production of iNOS results in the activation of guanylyl cyclase leading to the production of cGMP and smooth muscle relaxation. However, a parallel mechanism of action for NO via oxidative stress needs further investigation.

Plasma procalcitonin (PCT) is a highly specific marker for the diagnosis of bacterial infections and sepsis. PCT levels are usually low in viral infections, chronic inflammation or postsurgical states. The purpose of this study was to characterize PCT plasma levels in patients with various types of ileus at preoperative stage, where the other inducing factors such as a surgical stress are excluded. The prospective study was performed on 54 patients admitted to in-patient surgical department with a proven diagnosis of ileus. Patients were divided to three groups--obstructive, vascular and paralytic ileus. Plasma levels of PCT (Kryptor analysis), TNFalpha, IL-1beta, IL-6, cortisol (ELISA) and CRP (Kryptor ultrasensitive analysis) were estimated before any invasive procedure was realized. We demonstrated significant elevation of PCT in both obstructive ileus in adhesions and vascular ileus compared with healthy subjects (p 0.01). PCT levels were not elevated in paralytic ileus. The regression coefficient was the highest for PCT and CRP (r=0.78, p 0.01), for TNFalpha and IL-8 (r=0.76, p 0.01) in vascular ileus. There was no significant correlation between PCT and other inflammatory parameters. The different types of ileus induce an elevation of plasma PCT levels and PCT shows itself as an acute phase reactant. The highest PCT concentrations were presented in patients with vascular ileus, whereas paralytic ileus revealed similar cytokine and PCT pattern as in healthy subjects. Plasma PCT estimation extended to a measurement of CRP and IL-6 may become a useful complementary examination for diagnostics of acute abdomen in patients.

Clostridium difficile infection (CDI) is a disease of varying severity. Its manifestations range from mild diarrhea to life-threatening paralytic ileus, painful distension of the large bowel and sepsis. Another possible manifestation of the disease is recurrent colitis that can exhaust the patient. For establishing the diagnosis, the patient's stool should be examined with two or three different microbiological methods. Immunochemical testing for the presence of clostridial toxins A and B shows good specificity but poor sensitivity. Therefore, it must be combined with other methods: stool testing for glutamate dehydrogenase (Clostridium antigen), anaerobic culture or PCR detection. An alternative way of assessing the etiology is colonoscopic examination; the disease is confirmed if typical pseudomembrane isles are present in the bowel mucosa. The basic drugs to treat CDI are still metronidazole (oral or parenteral) and/or vancomycin (oral or rectal). Fidaxomicin seems to be promising. Stool transplant via a nasojejunal tube is effective in recurrent disease. In the hospital setting, patients suffering from CDI should be isolated for the entire duration of diarrhea. Surveillance rules should also be applied, together with early treatment of symptomatic patients and prevention of the spread of the infection. Higher incidence of CDI in a ward implies that the local antibiotic prescription habits should be revised.

Colorectal surgery is a necessity for many disease processes such as diverticulitis, ulcerative colitis, Crohn disease, and colorectal cancers as well as for the many complications of such conditions. The incidence of overall complications related to colorectal surgery has been reported to be between 10% and 30%. Prevention is the necessary key to avoid complications and this may be improved by adequate selection of appropriate procedures for the patient, good surgical technique, and good postoperative care. Nevertheless, complications do occur intraoperatively or postoperatively and must be managed in a timely manner to improve overall patient outcomes. Such complications include paralytic ileus, anastomotic leak, abdominal sepsis, acute mesenteric ischemia, anastomotic bleeding and hemorrhage, wound infection, anastomotic dehiscence and fistula formation, small bowel obstruction, and genitourinary complications.

Clostridium difficile infection (CDI) is a disease of varying severity. Its manifestations range from mild diarrhea to life-threatening paralytic ileus, painful distension of the large bowel, and sepsis. Another possible manifestation of the disease is recurring colitis that can exhaust the patient. For establishing the diagnosis, the patient's stool should be examined with two or three different microbiological methods (testing for clostridial toxins A and B; testing for clostridial glutamate dehydrogenase, anaerobic culture with specific media, or PCR detection of genes for production of clostridial toxins). An alternative way of assessing the etiology is colonoscopic examination; the disease is confirmed if characteristic patchy pseudomembranes are present in the bowel mucosa. Optimal treatment depends on severity of the disease and on the risk of recurrence. Metronidazole, vancomycin and fidaxomicin are used as basic drugs. Fecal transplantation is effective in recurrent disease. In the hospital setting, patients suffering from CDI should be isolated for the entire duration of diarrhea. Surveillance rules also should be applied, together with early treatment of symptomatic patients and prevention of the spread of the infection. Higher incidence of CDI in a ward implies that the local antibiotic prescription habits should be revised.

Peripartum haemorrhage is an obstetric emergency which requires effective and timely management. A retrospective analysis was conducted at a single centre district hospital, over a 10-year period to describe factors that would lead to a peripartum hysterectomy. We sought to establish intraoperative and postoperative risks and review outcomes and complications associated with the procedure. A total of 29 cases (incidence 0.8 per 1000) were reviewed over 2001-2011. The mean parity was 1.8 and the mean maternal age was 33 years. Uterine atony was the most common indication for hysterectomy (12/29) followed by placenta praevia and accreta (4/29 and 5/29 cases, resp.). The commonest postoperative complications were sepsis and paralytic ileus. EPH most commonly occurs due to uterine atony but remains difficult to predict. Hospitals should continue to have robust systems and the necessary resources available to perform EPH where clinically indicated.
