Cardiac dysfunction with pulmonary edema following scorpion envenomation (SE) has been documented only in a few isolated case reports. We conducted a systematic hemodynamic study in five consecutive patients (mean age, 21.6 +/- 8 years) presenting with pulmonary edema occurring a few hours (9.6 +/- 5.2 hours) after SE. All patients had increased pulmonary capillary wedge pressure (mean, 25 +/- 1.8 mm Hg) while the systemic vascular resistance was elevated only in one. The stroke volume index was markedly depressed (21.7 +/- 3.6 ml/sq m) whereas cardiac index was normal or slightly decreased (2.5 +/- 0.4 L/min/sq m). Cerebral infarct and sudden cardiac arrest were the cause of death in two patients. In the three survivors, all the hemodynamic disturbances and respiratory abnormalities disappeared within a few days. We conclude that cardiac dysfunction was found in all five patients and this was reversible in the three surviving the acute episode. 相似文献

IntroductionThe botryomycoma is a benign tumor that develops as a response to a local trauma. Generally, it occurs in the fingers, the face and the oral cavity. It is often easily recognized. However, the diagnosis between this tumor and other oral tumors, whether benign or malignant, may be difficult in some cases. We report a particular case of a botryomycoma that occurred with no history of a trauma at an earlier age in the tongue, which is an unusual site for this tumor.Case reportA 7-month-old infant presented with a polypoid and sessile swelling on the dorsal side of the tongue. This tumor gradually increased in size since birth. Clinically, the appearance of this mass with the gathered vessels inside was similar to that of a benign vascular tumor. A possibly malignant nature was not excluded. A complete resection under general anesthesia was performed. The histologic examination confirmed the diagnosis of pyogenic granuloma.DiscussionPyogenic granuloma is a rare benign tumor which is most likely to occur between the age of 11 and 40. The most frequent location encountered for oral cavity is the gingiva. The tongue is rarely a site for its occurrence. Cutaneous pyogenic granuloma may have different aspect from mucosal type and thus may make the diagnosis difficult. Treatment consists on surgical excision and removal of etiological factors that may be source of recurrence. 相似文献

Desmoplastic small round cell tumor (DSRCT) correspond to a recent clinicopathological entity, individualized in 1989 into the group of tumors with small round cells. This pathology puts ethiopathogenic, diagnostic, therapeutic and prognosis problems. Indeed, the ethiopathogenic is still unknown, diagnosis is asserted only by immuno-histochimic and cytogenetic study because of the big number of differential diagnoses and the anatomopathologic polymorphism. Its treatment is not well codified and its outcome remains dark in spite of therapeutic progress. The objective of this work is to report a personal observation of a DSRCT and to proceed to a review of the literature to clarify the epidemiological, clinical, paraclinical and therapeutic aspects of this rare tumor. 相似文献

The effects of aprotinin, a broad-based proteinase inhibitor, in the management of hemorrhagic complications during prolonged venovenous extracorporeal CO2 removal in patients with adult respiratory distress syndrome are not evaluated. In two patients, aprotinin infusion was added to heparin to treat bleeding, occurring after few days of bypass and responsible for respiratory and hemodynamic deterioration. After aprotinin infusion (loading dose of 2×106 kIU followed by a continuous infusion of 5×105 kIU/h) combined with heparin, bleeding vanished until the end of bypass. 相似文献

We report the neuroimaging findings of a case of reversible metronidazole-induced encephalopathy. Magnetic resonance imaging (MRI) demonstrated lesions in highly suggestive locations. Follow-up imaging performed 1 month after cessation of metronidazole therapy demonstrated resolution of imaging findings. 相似文献
