IL-18 is a new type of inflammatory cytokine similar to but distinct from IL-12 and IL-1beta. One intriguing property of IL-18 is synergism with IL-12 in many respects. In this study we examined the in vivo synergistic effects of IL-18/IL-12 in mice and found lethal toxicity accompanying an elevated IFN-gamma level in the serum. Since treatment with IL-18 alone did not have any apparent toxicity, and treatment with IL-12 alone showed only limited toxicity in our system, the synergy between the two cytokines was all the more remarkable. The major symptoms of the toxicity were weight loss,
diarrhea
, hemorrhagic colitis, splenomegaly, fatty liver, and atrophic thymus, most of which are similarly found in endotoxin-induced septic shock. However, in contrast to septic shock, TNF-alpha was not induced. The involvement of IFN-gamma in the toxicity was further studied in detail. Treatment of athymic nude mice with anti-asialo-GM1 did not reduce the toxicity, whereas anti-IFN-gamma treatment of wild-type mice alleviated it. When IFN-gamma-deficient mice were treated with IL-18/IL-12, the majority of them showed mortality and toxicity with severe
pulmonary edema
. These results indicate that IL-18/IL-12 treatment induces severe adverse effects through not only IFN-gamma-dependent mechanisms but also IFN-gamma-independent processes.

An unusual case diagnosed as connective tissue-type mast cell leukemia with marked mastocyte infiltration into visceral organs in a seven-year-old female Curly-Coated retriever is presented. Acute circulatory collapse, emesis,
diarrhea
, abdominal enlargement, icterus, cyanosis, dyspnea,
pulmonary edema
, hepatomegary, ascites, and right ventricular enlargement were observed. Hematologic and biochemical examinations revealed mast cell leukemia, mature neutrophilia, monocytosis, thrombocytopenia, hemolytic hyperbilirubinemia, hyperhistaminemia, renal and hepatic injuries. Mast cells were distributed systemically, but predominantly in the diaphragm and liver with a large mass among the serosa of ileum, cecum and colon. Mast cells were stained intensely by both safranin and berberine sulfate.

Direct bird-to-human transmission, with the production of severe respiratory disease and human mortality, is unique to the Hong Kong-origin H5N1 highly pathogenic avian influenza (HPAI) virus, which was originally isolated from a disease outbreak in chickens. The pathobiology of the A/chicken/Hong Kong/220/97 (H5N1) (HK/220) HPAI virus was investigated in chickens, turkeys, Japanese and Bobwhite quail, guinea fowl, pheasants, and partridges, where it produced 75-100% mortality within 10 days. Depression, mucoid
diarrhea
, and neurologic dysfunction were common clinical manifestations of disease. Grossly, the most severe and consistent lesions included splenomegaly,
pulmonary edema
and congestion, and hemorrhages in enteric lymphoid areas, on serosal surfaces, and in skeletal muscle. Histologic lesions were observed in multiple organs and were characterized by exudation, hemorrhage, necrosis, inflammation, or a combination of these features. The lung, heart, brain, spleen, and adrenal glands were the most consistently affected, and viral antigen was most often detected by immunohistochemistry in the parenchyma of these organs. The pathogenesis of infection with the HK/220 HPAI virus in these species was twofold. Early mortality occurring at 1-2 days postinoculation (DPI) corresponded to severe
pulmonary edema
and congestion and virus localization within the vascular endothelium. Mortality occurring after 2 DPI was related to systemic biochemical imbalance, multiorgan failure, or a combination of these factors. The pathobiologic features were analogous to those experimentally induced with other HPAI viruses in domestic poultry.

Although Tityus trivitattus is the only scorpion species reported to cause severe human envenomation in Argentina, no previous studies on its venom have been done. Telson homogenates from T. trivitattus specimens collected in Santiago del Estero, Cordoba, and Buenos Aires were employed to study their protein composition and toxicity to mice. Regardless of the site of collection, electrophoretic analysis showed bands at 205, 150, 100, 40, 32, and 13 kDa or smaller. FPLC gel filtration showed three major peaks and 6-8 minor peaks with similar elution volumes. One of the minor peaks from FPLC containing a component of approximately 8 kDa was lethal to mice. Mice injected intravenously with different doses of homogenates presented severe autonomic signs like tachypnea, tachycardia, sialorrhea, lacrimation, profuse sweating,
diarrhea
, dyspnea, and death. Pathology studies of lungs showed severe congestion of alveolar capillaries,
pulmonary edema
, and hemorrhagic areas. The kidneys showed glomerular as well as tubular lesions and exocrine glands showed areas of necrosis. The calculated LD50 was 0.38 +/- 0.08 telsons per 20 g mouse, which suggests a lethal potency similar to that of T. serrulatus venom. The lethal potency of 5.0 LD50 of T. trivitattus telson homogenate was neutralized by both an anti-T. trivitattus and a heterologous anti Tityus with ED50 values of 41 +/- 19 and 170 +/- 42 microl, respectively.

Cytomegalovirus causes pneumonia, hepatitis, thrombocytopenia, and hemolytic anemia. Cytomegalovirus adrenalitis in premature infants, however, is rare. This report described a premature newborn who had progressively worsening hyperbilirubinemia, pancytopenia, and hepatosplenomegaly at the age of 4 days. The baby's mother had prolonged rupture of amniotic membrane for about 8 weeks. The infant received exchange blood transfusion, empiric antibiotics treatment, and mechanical ventilation. Pneumonia and sepsis developed at the age of 18 days. Serum anticytomegalovirus immunoglobulin M and urine virus culture were positive for cytomegalovirus. The baby died at the age of 22 days. Autopsy showed cytomegalovirus infection complicated with interstitial pneumonitis and
pulmonary edema
, subacute bronchopulmonary dysplasia with interstitial fibrosis, and adrenalitis. We concluded that the functional status of the adrenal glands in cytomegalovirus-infected premature newborns who have unexplained electrolytes imbalance, fever,
diarrhea
, weight loss, or hypotension should be closely followed because of the possible involvement of adrenal glands.

In order to verify the safety of an ideal length of hospital stay (5-6 days) after open colectomy, we reviewed complications after 371 consecutive, elective colorectal resections for cancer at our institution between April 1991 and December 1998. Specifically, age of the patient, length of hospital stay and when the complication was diagnosed were registered. The median postoperative hospital stay was 9 days (range, 4-34 days). No difference in length of hospital stay was detected in patients < or = 65 years old versus > 65 years old (P = NS). All major complications (anastomotic leak, intestinal bleeding, intestinal occlusion, pneumonia, pulmonary embolism,
pulmonary edema
, stroke, angina pectoris, and fascial dehiscence) were diagnosed before the fifth postoperative day (P < 0.05). Among the minor complications (vomiting, packed red blood cells transfusion,
diarrhea
, wound infection, urinary tract infection, and pleural effusion), none requiring hospitalization was detected later then 5 days after the operation. We conclude that postoperative length of stay after colorectal resection for cancer can be reduced safely to five to six days after the operation.

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.

Pulmonary edema
is the primary danger in cardiac patients who undergo abortion by intra-amniotic instillation of hypertonic saline solution. The intra-amniotic saline has not been considered safe for induction of abortion in the 2nd trimester of pregnancy due to either immediate or late complications. Side effects range from vomiting,
diarrhea
, and headaches to severe septicaemea, convulsions, hemorrhage, disseminated intra-vascular coagulation, and
pulmonary edema
.
Pulmonary edema
is often unanticipated in women with "tight" mitral stenosis which was unrecognized in pregnancy. Organic lesion in the heart is often undetected prior to instillation of hypertonic saline which could subsequently cause cardiac failure and
lung edema
.

DMSO is an amphipathic molecule with a highly polar domain and two apolar methyl groups, making it soluble in both aqueous and organic media. It is one of the most common solvents for the in vivo administration of several water-insoluble substances. Despite being frequently used as a solvent in biological studies and as a vehicle for drug therapy, the side-effects of DMSO (undesirable for these purposes) are apparent from its utilization in the laboratory (both in vivo and in vitro) and in clinical settings. DMSO is a hydrogen-bound disrupter, cell-differentiating agent, hydroxyl radical scavenger, intercellular electrical uncoupler, intracellular low-density lipoprotein-derived cholesterol mobilizing agent, cryoprotectant, solubilizing agent used in sample preparation for electron microscopy, antidote to the extravasation of vesicant anticancer agents, and topical analgesic. Additionally, it is used in the treatment of brain edema, amyloidosis, interstitial cystitis, and schizophrenia. Several systemic side-effects from the use of DMSO have been reported, namely nausea, vomiting,
diarrhea
, hemolysis, rashes, renal failure, hypertension, bradycardia, heart block,
pulmonary edema
, cardiac arrest, and bronchospasm. Looking at the multitude of effects of DMSO brought to light by these studies, it is easily understood how many researchers working with DMSO (or studying one of its specific effects) might not be fully aware of the experiences of other groups who are working with it but in a different context.

Sodium azide, used mainly as a preservative in aqueous laboratory reagents and biologic fluids and as a fuel in automobile airbag gas generants, has caused deaths for decades. Its exposure potential for the general population increases as the use of airbags increase. In order to characterize the known health effects of sodium azide in humans and the circumstances of their exposure, the authors conducted a systematic review of the literature from 1927 to 2002 on human exposure to sodium azide and its health effects. The most commonly reported health effect from azide exposure is hypotension, almost independent of route of exposure. Most industrial exposures are by inhalation. Most laboratory exposures or suicide attempts are by ingestion. Most of the reported cases involved persons working in laboratories. The time between exposure and detection of hypotension can predict outcome. Fatal doses occur with exposures of >or=700 mg (10 mg/kg). Nonlethal doses ranged from 0.3 to 150 mg (0.004 to 2 mg/kg). Onset of hypotension within minutes or in less than an hour is indicative of a pharmacological response and a benign course. Hypotension with late onset (>1 hour) constitutes an ominous sign for death. All individuals with hypotension for more than an hour died. Additional health effects included mild complaints of nausea, vomiting,
diarrhea
, headache, dizziness, temporary loss of vision, palpitation, dyspnea, or temporary loss of consciousness or mental status decrease. More severe symptoms and signs included marked decreased mental status, seizure, coma, arrhythmia, tachypnea,
pulmonary edema
, metabolic acidosis, and cardiorespiratory arrest. The signs and symptoms from lower exposures (<700 mg) are physiological responses at the vascular level and those at or above are toxicological responses at the metabolic level. There is no specific antidote for sodium azide intoxication. Recommended preventive measures for sodium azide exposure consist of education of people at high risk, such as laboratory workers, regarding its chemical properties and toxicity, better labeling of products containing sodium azide, and strict enforcement of laboratory regulations and access control.
