Patterns of gastrointestinal hemorrhage in hemophilia

Peptic ulcer has been reported to be the cause of bleeding in 53%-85% of hemophiliacs with gastrointestinal hemorrhage (GIH). The management of GIH in hemophiliacs during the past decade has been affected by the availability of plasma concentrates, an increasing occurrence of chronic liver disease, and widespread use of endoscopic procedures. To determine the present patterns of GIH, we reviewed our experience at the Hemophilia Center of Western Pennsylvania during the last 10 yr. Twenty-five (10.3%) of 243 hemophiliacs experienced 41 episodes of GIH. The severity of hemophilia and a history of retroperitoneal hemorrhage were significant risk factors for GIH. Duodenal ulcer (22%), unknown site (22%), and gastritis (14%) were the three most common diagnoses. The use of fiberoptic endoscopy resulted in the recognition of diagnoses such as gastritis, esophagitis, Mallory--Weiss syndrome, and esophageal varices. Red cell transfusion requirements of hemophiliacs with GIH were no different than those of nonhemophiliacs with GIH (p greater than 0.05). The amount of factor VIII replacement used by hemophiliacs with GIH correlated with the severity of gastrointestinal bleeding (p less than 0.01), but not with the cause of gastrointestinal bleeding (p greater than 0.05). In conclusion, hemophiliacs develop GIH secondary to a variety of causes as do nonhemophiliacs. Fiberoptic endoscopy, after correction of factor VIII level to 0.40 U/ml, is a safe and valuable diagnostic procedure in hemophiliacs. The specific etiology of GIH in hemophiliacs should be aggressively sought and appropriate specific therapy provided.

Accuracy of computerized tomography in determining hepatic tumor size in patients receiving liver transplantation or resection

Computerized tomography (CT) of liver is used in oncologic practice for staging tumors, evaluating response to treatment, and screening patients for hepatic resection. Because of the impact of CT liver scan on major treatment decisions, it is important to assess its accuracy. Patients undergoing liver transplantation or resection provide a unique opportunity to test the accuracy of hepatic-imaging techniques by comparison of findings of preoperative CT scan with those at gross pathologic examination of resected specimens. Forty-one patients who had partial hepatic resection (34 patients) or liver transplantation (eight patients) for malignant (30 patients) or benign (11 patients) tumors were evaluable. Eight (47%) of 17 patients with primary malignant liver tumors, four (31%) of 13 patients with metastatic liver tumors, and two (20%) of 10 patients with benign liver tumors had tumor nodules in resected specimens that were not apparent on preoperative CT studies. These nodules varied in size from 0.1 to 1.6 cm. While 11 of 14 of these nodules were less than 1.0 cm, three of 14 were greater than 1.0 cm. These results suggest that conventional CT alone may be insufficient to accurately determine the presence or absence of liver metastases, extent of liver involvement, or response of hepatic metastases to treatment.

Polyarthritis with atypical keratotic nodular dermatosis or polyarthritis with multiple keratoacanthoma. A case report

We report an interesting case of generalized papular and nodular lesions with central keratinous plugs and severe hyperkeratotic-acanthotic histopathology with arthritis in a 19-year-old male patient who had suffered from a similar disease 2 years earlier. Papules and nodules erupted a few days after the arthritis and this was noticed during both episodes. On healing, nodules fell spontaneously leaving behind insignificant hyperpigmented scars.

Incontinentia pigmenti et achromians

A case is reported, apparently the first of its kind in the literature, of a female child in which there were not only pigmented lesions of incontinentia pigmenti but also hypopigmented lesions of incontinentia pigmenti achromians. The title incontinentia pigmenti et achromians is suggested for this combined disorder. The child also had associated lesions in the form of nail dystrophy, delayed dentition and epilepsy.
