Remission of autoimmune hepatitis during pregnancy: a report of two cases.

Little is known about the evolution of autoimmune hepatitis (AIH) during pregnancy. Some authors reported worsening of the liver disease during pregnancy, whereas others reported stable conditions. We present two untreated patients who had remission of the autoimmune hepatitis in the second half of their pregnancies. One of the patients exhibited this phenomenon twice during two consecutive pregnancies. We speculate that the immunosuppressive effect of pregnancy induced remission of the autoimmune hepatitis in our patients.

Multiple focal nodular hyperplasia.

Focal nodular hyperplasia (FNH) is a benign lesion of the liver which usually presents with one or two localizations. We report a patient with history of resection of a biliary cyst, and who had been taking oral contraceptives for the past 18 years, who had multiple localizations of FNH (more than 30 lesions). The largest lesion measured 10.5 x 11 x 12cm. The imaging characteristics of our patient were atypical. A central scar could be demonstrated only in the largest lesion, in an eccentric location. In the other lesions, no scar formations could be detected. Furthermore, imaging characteristics suggested that several of the lesions contained fat. This was confirmed by biopsy. The patient had an associated inflammatory syndrome which could not be otherwise explained. The patient was advised to stop taking the oral contraceptives. Follow-up after 2 years showed that the lesions were unchanged; the inflammatory syndrome persisted. Multiple localizations of FNH are very rare. Sometimes they are associated with malformations in other organs (vascular malformations and neoplasia, mostly of the brain). Often they occur as isolated cases, however. Usually their prognosis seems to be good.

Granulocytic sarcoma (chloroma): a report of two cases.

Granulocytic sarcoma or chloroma is defined as an extramedullary solid tumor, composed of granulocytic precursor cells at various levels of differentiation. Granulocytic sarcoma is mostly associated with acute and chronic leukemia, rarely with polycythemia vera and myelofibrosis. The use of special immuno-histochemical stains is mandatory, because this tumor is often misdiagnosed as malignant lymphoma. We report two cases of granulocytic sarcoma (tonsil and ovary) associated with chronic myelogenous leukemia. We describe the first reported association of atypical CML and granulocytic sarcoma.

Epidural abscess: case report and review of the literature.

Spinal epidural abscess is an uncommon site of infection, resulting in back pain, fever, weakness and loss of sensibility. These signs should suggest the diagnosis, and quick confirmation by MRI should be performed. Immediate surgical decompression and antibiotherapy is necessary, because this is the base of a possible successful functional recovery. Empiric therapy consisting of high dose of penicillinase-resistant antibiotics is advised because most often an epidural abscess is caused by Staphylococcus aureus. However, because other bacteria can be involved, an aminoglycoside or a cephalosporin should be added to the empiric treatment, until the results of the cultures are known. When diagnosis and therapy are delayed, permanent paralysis and death are common.
