Thirteen children with intramural haematoma of the alimentary tract were treated in Chulalongkorn University Hospital during an 8-year period (1978-1986). A history of trauma was obtained in 11 cases, 1 case presented as a result of a coagulation defect secondary to a haematotoxic snake bite and no causative factor was apparent in 1 patient. Profound vomiting with abdominal pain is the typical presentation. Upper gastrointestinal contrast study is usually characteristic and diagnostic. Conservative treatment was successful in 12 of the cases with no morbidity and mortality.

Four patients had pancreatitis associated with valproic acid therapy. Three patients received valproic acid at usual doses, and all were free of other symptoms of toxic reactions, with serum levels of valproic acid in the usual therapeutic range. Two patients underwent exploratory laparotomy prior to diagnosis. Complications included pseudocyst, pericardial effusion, laparotomy wound infection, and coagulopathy. All patients recovered with discontinuation of valproic acid therapy and enteral feeding and administration of intravenous fluids. After recovery, a valproic acid regimen was restarted uneventfully (in one patient). All were asymptomatic with normal serum amylase levels after five to 14 months. Pancreatitis is a serious complication of valproic acid therapy that must be considered in any patient receiving valproic acid who experiences severe abdominal pain and vomiting.

Strychnine toxicosis is characterized by inducible tetanic seizures and metaldehyde poisoning by fine fasciculations progressing to generalized tremors and seizures. Intoxication with 1080 causes seizures, random running movements, vomiting, defecation, urination, acidosis and hyperglycemia. Intoxication with rodenticides causing coagulopathy is characterized by hemorrhage into body cavities but not necessarily external hemorrhage. Anticholinesterase insecticides cause salivation, urination and defecation, while chlorinated hydrocarbon insecticides cause CNS disturbances. Ethylene glycol intoxication results in ataxia, depression, coma, vomiting and tachypnea, followed by acute renal failure. Urea poisoning causes bloat and CNS signs in cattle. Monensin intoxication in horses lasts several days and causes stiffness, colic, uneasiness and recumbency. Salt poisoning results in depression, seizures and hypernatremia. Lead poisoning is associated with central and peripheral nervous system signs, as well as increased numbers of nucleated RBC and basophilic stippling of RBC. Arsenic poisoning results in GI pain, diarrhea, weakness and death. Copper toxicosis in sheep is manifested by hemolytic anemia, hemoglobinemia and hemoglobinuria. Plants that may intoxicate domestic animals include sorghum, greasewood, halogeton, water hemlock, Japanese yew, larkspur, lupine, milk-weed, philodendron, oleander, castor bean and precatory bean.

A fatal case of oral ingestion of potassium dichromate is presented. Following an initial presentation of abdominal pain and vomiting, the patient had a rapid progression to coma with the development of methemoglobinemia, coagulopathy, gastrointestinal hemorrhage, and respiratory distress syndrome. A blood concentration of chromium on admission was 5,800 mcg/dL, 80% of which was found to be in the intracellular fraction. Supportive treatment was also initiated as a four-hour period of hemodialysis followed by a one-hour period of charcoal hemoperfusion. Neither of these treatment modalities was found to significantly remove chromium from whole blood and neither seemed to affect the progression or outcome of this intoxication. We conclude that the ingestion of potassium dichromate is highly toxic and may rapidly lead to death. Hemodialysis and charcoal hemoperfusion appear to have little role in the management of chromium intoxication.

An 18-month-old boy presented with a 5-day history of lethargy, fever, vomiting and rash. He required intensive care for inotropic and ventilatory support. He developed a disseminated intravascular coagulopathy and gangrene of his extremities. In addition, he had severe neurological dysfunction and loss of vision, both of which recovered spontaneously with time. The potential severity of tick typhus caused by Rickettsia conorii is described as well as the importance of paired serological tests in the diagnosis of this condition.

Seven Saudi children bitten by Echis colorata, a species of carpet viper encountered mainly in the Middle East, were studied in south-western Saudi Arabia. They all showed severe local signs of swelling, ecchymosis and blisters, and one also had local necrosis. Four children had systemic envenoming with vomiting and hypotension, and one child had acute renal failure. Three of them had prolonged prothrombin and partial thromboplastin times and hypofibrinogenaemia resulting from disseminated intravascular coagulopathy. They were initially managed in the intensive care unit and received intravenous fluids and polyvalent antivenom. Apart from one child who required skin grafting for local necrosis, complete recovery with no sequelae occurred in all cases.

Iron poisoning is the most common cause of overdose mortality in children under six years of age and there are no reports of survival with iron levels > 2687 mumol/L (> 15,000 micrograms/dL). A 22-month-old male was brought to the emergency department by his parents after ingesting an estimated 50 ferrous sulfate tablets (60 mg elemental iron/tablet) several hours earlier. Despite spontaneous emesis and gastric lavage his condition deteriorated and he was found to have a serum iron of 2992 mumol/L (16,706 micrograms/dL). During the first four days in the intensive care unit, he developed coma, metabolic acidosis, hypovolemic and cardiogenic shock, liver failure, coagulopathy and adult respiratory distress syndrome. He was treated with a unique deferoxamine dosage schedule (25 mg/kg/h for 12 h/d x 3 d), mechanical ventilation, Swan-Ganz catheter monitoring, dopamine/nitroprusside therapy, blood product, bicarbonate, electrolyte and volume replacement. After a prolonged hospital course complicated primarily by gastric outlet obstruction he was dismissed on full oral feedings, gaining weight, and neurologically intact. Swan-Ganz catheter monitoring guided the management of this patient's shock, iron-induced cardiac failure, and deferoxamine mesylate induced adult respiratory distress syndrome. Further experience and research is required to determine the most appropriate deferoxamine mesylate dosing schedule and our experience expands the range for possible survival after massive iron overdose.

Aetiologic factors (gallstones, hyperlipidemia I-IV, hypertriglyceridaemia) make their occurrence, mainly, in the third trimester of gestation. Two cases of acute pancreatitis in pregnancy are described; in both cases patients referred healthy diet, no habit to smoke and no previous episode of pancreatitis. An obstructive pathology of biliary tract was the aetiologic factor. Vomiting, upper abdominal pain are aspecific symptoms that impose a differential diagnosis with acute appendicitis, cholecystitis and obstructive intestinal pathology. Laboratory data (elevated serum amylase and lipase levels) and ultrasonography carry out an accurate diagnosis. The management of acute pancreatitis is based on the use of symptomatic drugs, a low fat diet alternated to the parenteral nutrition when triglycerides levels are more than 28 mmol/L. Surgical therapy, used only in case of obstructive pathology of biliary tract, is optimally collected in the third trimester or immediately after postpartum. Our patients, treated only medically, delivered respectively at 38th and 40th week of gestation. Tempestivity of diagnosis and appropriate therapy permit to improve prognosis of a pathology that, although really associated with pregnancy, presents high maternal mortality (37%) cause of complications (shock, coagulopathy, acute respiratory insufficiency) and fetal (37.9%) by occurrence of preterm delivery.

This case presentation will discuss the pathophysiology of a child in septic shock due to Neisseria meningitidis. The most prevalent nursing care concerns of this case encountered during the pediatric intensive care unit (PICU) and during the general floor stay will be addressed. The nursing skill required for identifying problems and planning care that clearly fall under the nursing domain also will be covered. In addition, the complexities of this case demonstrate that collaboration between the PICU nurse and the general pediatric nurse is imperative for successful patient outcome. A.W. was a 5 1/2-month-old infant transported to our PICU from a referral hospital in the state. Diagnosis at time of admission was meningococcemia, disseminated intravascular coagulopathy, septic shock, respiratory failure, and purpura fulminans. There was a 2- to 3-day history of a runny nose, cough, and vomiting. On the day of admission, A.W. had three seizures and developed a fever and a purpuric rash.

We report a rare case of non-menstrual toxic shock syndrome (TSS) in the course of Staphylococcus aureus sepsis in a 31-year-old primigravida who developed high fever and severe pulmonary and cardiovascular failure within a few hours at the end of the 29th week of a twin pregnancy. Mechanical ventilation was necessary due to signs of adult respiratory distress syndrome (ARDS) and catecholamines were needed to maintain a somewhat adequate blood pressure. A forceps delivery was performed immediately. Postoperatively, the patient was brought to the intensive care unit (ICU) due to the suspicion of severe septic shock. In addition to the extreme cardiovascular instability and massive disturbance of pulmonary gas exchange, the clinical picture was characterised by a disseminated intravascular coagulopathy (DIC) with marked petechial bleeding and ecchymoses on all extremities. Moreover, a confluent, spotty exanthem of the trunk and extremities could be seen. Despite all therapeutic efforts, the patient died within a few hours after admission to the ICU with signs of multiorgan failure. Post-mortem, multiple staphylococcal abscesses were found in the kidneys, liver, and uterus. Moreover, acute ulcerous endocarditis of the mitral valve and septic myocardial foci with myocarditis were seen. The Staph. aureus strain isolated from the blood cultures was shown to produce TSS toxin 1 (TSST-1) and enterotoxin B. In summary, the clinical picture can be interpreted as severe staphylococcal sepsis complicated by TSS. TSS is a specific type of infectious disease, occurring mainly in young women during the menstrual period (80%-90%), but it has also been reported in non-menstrual cases (10%-20%). It is characterised by sudden-onset high fever, hypotension, rash, mucosal hyperaemia, and various additional symptoms such as myalgia, vomiting, and diarrhoea. The clinical course depends on the extent of the organ failure due to decreased tissue perfusion during hypotension. Severe cases are accompanied by multiple organ-system failure including impaired renal function, which is reversible in nearly all cases. Respiratory failure ranges from interstitial and alveolar aedema to ARDS in 10% of cases; severe DIC is seen in 10%-15%. Another severe clinical complication is cardiac insufficiency. The etiology of TSS is based on a localized or, rarely, systemic infection with certain Staph. aureus strains that are capable of producing toxins, the most important one being TSST-1. Staph. aureus strains can also produce various other enterotoxins that may be involved in the pathogenesis of TSS. The pathogenetic importance of the toxins is supported by the antibody titers in TSS patients: more than 80% of healthy adults show high levels of antibody titers, whereas 90% of TSS patients exhibit low levels in the acute phase followed by a significant increase during convalescence. It is not clear whether the toxins cause TSS by a direct effect or by release of mediators due to their function as superantigens. The clinical characteristics of non-menstrual TSS are identical to those of menstrual TSS, but it can occur in many clinical settings in both sexes at any age. Severe clinical courses are more frequent in non-menstrual TSS: the mortality is about 8%-11% in non-menstrual TSS compared to 2%-5% in menstrual TSS. The diagnosis is based mainly on clinical signs and the isolation of toxin-producing Staph. aureus strains. Besides antibiotic therapy, treatment is primarily directed to the correction of hypotension and additional organ-system failure. Other therapeutic measures such as the elimination of toxins by plasma separation or the administration of antibodies or gamma-globulins are subjects of investigation with no general recommendations at this time.
