Symptoms of exposure Hematuria, back pain, hematoma in arms, legs epistaxis, bleeding lips, mucous membrane hemorrhage, abdominal pain, vomiting, fecal blood petechial rash abnormal hematology (NIOSH, 1987)... 

Lethal doses may be absorbed through the skin local irritation is usually slight. Skin application of 50g of a 25% dinitro-o-cresol ointment to a 4-year-old boy caused vomiting, headache, yellow stained skin and sclera, elevated pulse and respiratory rate, unconsciousness, and death within 3.5 hours. Autopsy showed diffuse petechial hemorrhages in the intestinal mucosa and brain, as well as pulmonary edema. 

In fatal cases, the pathologic findings are entirely nonspecific. They usually consist of petechial hemorrhages and congestion of the organs, indicating combined action of severe convulsions and anoxia. Compression fractures and related injury may be found in cases with violent tetany. ... 

Hemorrhagic tendency may be manifested by hematuria, skin petechiae, hemorrhage into or from a wound or ulcerating lesion, or petechial and purpuric hemorrhages throughout the body.

In the previous sections we have, by part, already reviewed delayed effects after cerebral ischemia, such as the risk of hemorrhagic complications that may occur as petechial bleedings or parenchymal hematoma. We have seen that the blood-brain barrier opens to various degrees with a substantial time... 

Hemorrhagic Illness. The viral hemorrhagic fevers include diseases caused by a number of different viruses. The clinical manifestations are characteristically severe, including shock, disseminated intravascular coagulation (Die), and other signs of increased vascular permeability (Borio et al., 2002 Franz et al., 1997). A macular or petechial rash is also typical for many of the viral hemorrhagic fevers. 

Information on the acute oral toxicity of sulfur mustard is quite limited. The oral LDl, for humans has been estimated to be 0.7 mg/kg (DA, 1992). The oral LD50 for rats is 17 mg/kg (DA, 1974). Rats treated with 2.5 mg/ kg/day for 14 days developed inflammation, petechial hemorrhage, thickening, and sloughing of the gastric mucosa (Hackett et al., 1987). 

S. pneumoniae is a common cause of acute bacterial conjunctivitis in children (Figure 25-5). Concurrent upper respiratory tract infections and otitis media, especially in children younger than 4 years, are common. In moderate climates S. pneumoniae is often the cause of acute bacterial conjunctivitis epidemics. This condition commonly presents with diffusely scattered petechial hemorrhages, especially on the superior bulbar conjunctiva, a mucopurulent discharge in the lower fornix, and transient marginal corneal infiltrates. Pseudomembranes may form.
