A study was undertaken to determine the criteria for ordering abdominal computed tomography (CT) in the emergency department (ED) for stable patients who sustained blunt trauma and to identify a patient population at high risk for having intra-abdominal injury (IAI) utilizing physical examination, decrease in hematocrit, and hematuria. Patients in a university ED who had abdominal CT from April 1995 to October 1995 were evaluated prospectively. Before the scan, the examining physician completed an entry form that included physical findings, hematocrit, hematuria, Glasgow Coma Scale score, intoxication, distracting injuries, reasons for obtaining the scan, and planned disposition. Patients were followed until discharge. A total of 196 patients were evaluated. Abdominal tenderness was present in 120 patients. Twenty-two patients had IAI. Eight required surgical intervention, and all 8 had abdominal tenderness. A total of 40 potential trauma admissions were averted by obtaining CT within the ED. The combined abnormal abdomen examination and presence of hematuria had a sensitivity of 64%, specificity of 94%, positive predictive value of 56%, and negative predictive value of 95%. Decrease of > or = 5 in hematocrit was not statistically significant for detection of IAI. CT had no false negatives in this cohort. These results show that early CT scanning of stable patients who have sustained blunt trauma is an effective screen for IAI and may result in fewer total admissions, but has potential for overuse. Patients with abdominal pain and hematuria should be scanned. The benefit of a CT scan for patients without tenderness or with an isolated decrease in hematocrit is questionable.

A 33 years old woman presented with cramp-like abdominal pain. Ultrasound examination revealed multiple lesions in the liver of hyper- and hypoechoic echogenicity which in accordance to subsequently performed computed tomography and dynamic hepatobiliary scintigraphy were considered to be a focal nodular hyperplasia (FNH). A severe increase of the serum lipase concentration, suspected to be an acute pancreatitis, was treated conservatively and led to a short improvement of symptoms. Some months later, a severe progression of the pain symptoms occurred, along with a measurable expansion of the abdominal circumference and palpable tumors of the liver. The dynamic hepatobiliary imaging and the static liver scan showed a decreased perfusion and function of the nodes as well as a reduced RES activity, respectively. A subsequently performed Positron Emission Tomography (PET) with F-18-Fluorodeoxyglucose (FDG) showed a massively increased glucose metabolism of the liver tumors. The histologic result of several biopsies of the tumors revealed metastases of an acinus cell carcinoma of the pancreas. Under systemic and local chemotherapy, a temporary remission could be obtained that was clearly detectable in a second FDG-PET. Nevertheless, during the further course of the disease, a progression occurred being detectable in an additional control PET-study by an increase in tumor size as well as in tumor glucose metabolism. The patient died in liver coma 15 months after the histologic diagnosis was obtained.

Degos' disease is a rare multisystem vasculopathy of unknown etiology. We report a 44-year-old man who presented himself with gait and sensory disturbances mainly due to thoracic transverse myelopathy four years after the appearance of many characteristic umbilicated papules over the trunk and extremities. He did not complain of abdominal pain or discomfort. Laboratory, electrophysiological and imaging studies did not show any characteristic change, except for the increase of protein contents and cell counts in the cerebrospinal fluid. We tried methylprednisolone pulse-dose therapy (1,000 mg/day x 3 days) five times, but this patient's neurological condition worsened stepwise after it, although the appearance of new skin lesion was suppressed. Intravenous infusion of ozagrel sodium and cyclophosphamide (1,000 mg/day) were also ineffective, and this patient died of respiratory failure after showing oculomotor paresis and comatose state. Necropsy revealed Degos' disease-specific vasculopathy in the central nervous system and the gastrointestinal tract, where occlusions of small-sized arteries and veins due to the intimal thickening were evident. The tissue necrosis was macroscopically remarkable in the brainstem and the thoracic spinal cord. The efficacy of steroid therapy for this disease should be investigated more carefully.

The most venomous scorpion species are Buthotus tamulus of India, the Leiurus quinquestriatus and Androctonus crassicauda of North Africa and the Middle East, the Tityus serrulatus of Brazil, and the Centruroides suffussus of Mexico. The severity of scorpion envenomation varies with the scorpion's species, age, and size, and is much greater in children. Systemic intoxication reflects the overstimulation of the CNS, the sympathetic and parasympathetic nervous system. Severity ranges from local pain and paresthesia to fatal cardiotoxicity and encephalopathy. Symptoms include: agitation, tachycardia, vomiting, abdominal pain, salivation, diaphoresis, dehydration, muscle rigidity and twitching, tremor, seizures, coma, pupillary changes, hyperthermia, tachyarrythmias and occasionally bradyarrhythmias, hypertension, and less often hypotension, cardiac failure, and priapism in males. Laboratory abnormalities include: hyperglycemia, leucocytosis, transient elevation of cardiac and pancreatic enzymes, ischemic changes in the ECG, and evidence of cardiac dysfunction on echocardiography. The principles of management are: observation, cardiac monitoring, supportive treatment with intravenous fluids and electrolytes, and a meticulous use of cardiovascular agents: vasodilators, adrenergic antagonists, or calcium channel blockers in the hypertensive phase; and inotropic agents in the event of hypotension. Antiarrhythmics such as lidocaine, may be required. There is increasing evidence for the efficacy of specific antivenom. The advance in supportive care and antivenom efficacy has markedly improved the outcome of patients with scorpion envenomation.

In February 1998, an outbreak of acute febrile illness was reported from the Kapalata military camp in Kisangani, the Democratic Republic of Congo. The illness was characterized by an acute onset of fever associated with severe headache, arthralgia, backache, neurologic signs, abdominal pain, and coughing. In 1 individual, hemorrhagic manifestations were observed. The neurologic signs included an altered level of consciousness, convulsions, and coma. Malaria was initially suspected, but the patients showed negative blood films and failed to respond to antimicrobial drugs. A total of 35 sera collected from the military patients in the acute phase were tested for the presence of IgM against vector-borne agents. Serum IgM antibodies against West Nile fever virus were found in 23 patients (66%), against Chikungunya virus in 12 patients (34%), against dengue virus in 1 patient (3%), and against Rickettsia typhi in 1 patient (3%). All sera were negative for IgM antibody against Rift Valley fever virus, Crimean Congo hemorrhagic fever virus, and Sindbis virus. These data suggest that infections with West Nile fever virus have been the main cause of the outbreak.

We report the case of a 33 year-old woman at the second quarter of pregnancy, with known brain aneurysm admitted in intensive care unit for sudden coma. The coma was not related to a rupture of the brain aneurysm but to a serious haemorrhagic shock caused by a spontaneous splenic rupture. This case report illustrates the difficulty of this unrecognized diagnosis and reminds us to suspect a spontaneous splenic rupture in front of any pregnant woman with atypic abdominal pain and haemorrhagic shock.

A case of somatostatin-producing pancreatic tumor associated with severe insulin-dependent diabetes mellitus and ketoacidotic coma is reported. The tumor, a 10-cm expansile mass arising from the pancreatic tail of a 70-yr-old woman, was first detected by ultrasonography, performed because of abdominal pain, and subsequently confirmed by computed tomography and fine-needle tumor aspiration. Pathologic investigation showed a predominantly solid-trabecular structure with scattered microacini and psammomatous bodies. A large proportion of tumor cells expressed somatostatin and/or calcitonin. Following resection of the primary tumor and three peripancreatic lymph nodes with metastases, the patient recovered rapidly from her diabetic syndrome and remained in substantially good health during a subsequent 8-yr follow-up period, without evidence of tumor recurrence.

Common krait (Bungarus caeruleus) is the deadliest snake found commonly in the dry zone of Sri Lanka. In Anuradhapura, 210 farmers bitten by the common krait over a three year period were investigated prospectively from 1 January 1996. The sex ratio was equal, 110 (52%) patients were in the age group 10-30 years. One hundred and one (48%) patients were severely envenomed and needed mechanical ventilation from 12 hours to 29 days (mode two days). The bite occurred at night while the victims were asleep on the floor. In 99 (47%) situations killed specimens were available for identification. The cardinal symptom was abdominal pain developing within hours of the bite. Alteration in the level of consciousness was observed in 150 (71%) patients: drowsy in 91 (43%), semiconscious in 24 (11%), and deep coma in 35 (17%). Autonomic disturbances included transient hypertension, tachycardia, lacrimation, sweating, and salivation. These manifested in 139 (66%) patients with moderate to severe envenomation. One hundred and forty nine (71%) had hypokalaemia and 105 (50%) metabolic acidosis, anterograde memory loss in 84 (40%), and delayed neuropathy in 38 (22%) patients. Polyvalent antivenom had no significant benefit (t = 0.5) in reversing respiratory paralysis and preventing delayed neurological complications. Sixteen (7.6%) patients died and a submucosal haemorrhage in the stomach was seen at necropsy in three cases. Mortality could be minimised with early and free access to mechanical ventilation.

Acute liver failure and haemolytic syndrome appeared quite suddenly as the first manifestations of Wilson disease (WD) in five of our patients previously regarded as healthy persons (although an interview showed that 2-4 weeks prior to the illness the patients complained of several non-specific symptoms, such as abdominal pain, headaches, fever, weakness or behavioural changes). All the patients were young women (17-23 years), none of them had any history of liver disease. They were admitted with icterus, nausea, vomiting and symptoms of increasing haemolysis. The diagnosis of WD was given as disturbed copper metabolism. After a short period of observation ascites and anasarca occurred, haemorrhagic diathesis and other symptoms of liver failure increased. Levels of clotting factors decreased rapidly. Despite treatment with D-penicillamine, plasmapheresis, and symptomatic drugs, three of the women died in irreversible liver coma, due to the unavailability of liver transplantation. The fourth woman was carried to the Transplantation Centre, due to aggravation of the symptoms of liver failure, where liver transplantation was performed. Histopathologically micronodular cirrhosis was shown in all these cases. The fifth patient survived having undergone the above treatment without liver transplantation. The main differences between the patient who survived and those who died or underwent transplantation were relatively higher activity of alkaline phosphatase (26 U/l vs. 10-20 U/l), slightly higher levels of clotting factors and prothrombin time, which never fall below 68% of the control (versus 14-44% in other patients). Only in the surviving patient was the Kayser-Fleischer ring present. In four of our patients we found family members who were carriers of WD.

Severe or complicated malaria is defined by infestation by Plasmodium falciparum into all red blood cells, especially those in the brain, causing coma and repeated convulsions; severe anemia (6 g/dl hemoglobin, 20% hematocrit); renal insufficiency (265 mcmol/l creatinine, 400 ml/day diuresis); pulmonary edema; hypoglycemia (2.2 ml/l or 0.4 g/l); shock; diffuse hemorrhaging; massive hemoglobinuria; and blood acidosis. Other possible symptoms of severe malaria are clouded thinking, changes in behavior, and inability to focus. It is most common in people with no immunity to malaria (children aged 4 and travelers in endemic zones). Pregnancy, splenectomy, corticotherapy, or poorly maintained immunity status favor severe anemia in adults. Sources of chloroquine-resistant P. falciparum have existed since 1960. Resistance has since expanded from Southeast Asia and South America to Africa, posing treatment problems. Malaria usually begins with fever (40 or more degrees Celsius), headaches, muscular pain, digestive troubles (e.g., diarrhea, nausea, or vomiting), and abdominal pain. In suspected cases of malaria, a blood sample or a thick blood smear as well as treatment (even in the absence of parasitological proof) needs to be done as soon as possible. Intravenous quinine diluted in a 5-10% glucose solution should be delivered at a rate of 24 mg/kg/day. In the case of severe jaundice, the dose should be cut in half beginning 8 hours after treatment began. If intravenous delivery is impossible, intramuscular delivery should be done. Corticosteroids, anticoagulants, and aspirin are contraindicated. In 2-4 days, oral administration (chloroquine, halofantrine, or mefloquine) is warranted. 20% of malaria-related deaths among patients who receive treatment are due to complications of the central nervous system. Protection against mosquito bites prevents malaria. Chemoprophylaxis in endemic zones should be limited to short trips to malaria zones or to pregnant women.
