Successful medical management of neutropenic enterocolitis in adults with acute leukemia.

Seven adults with acute leukemia had a clinical and radiologic diagnosis of neutropenic enterocolitis. Six of the seven patients had granulocyte counts less than 500/microliter. All seven patients responded to intensive medical therapy, including bowel rest, broad spectrum antibiotics, and white blood cell transfusions, and recovered from the neutropenic enterocolitis without surgical intervention. We discuss the clinical spectrum of neutropenic enterocolitis and the favorable results of medical therapy.

Disseminated Geotrichum candidum infection.

The pathogenicity of the fungus Geotrichum candidum in humans has not been clearly defined. A patient with acute leukemia who developed a fatal disseminated G. candidum infection while neutropenic is described. At autopsy examination, this patient was misdiagnosed on the basis of histopathology as having disseminated candidiasis until G. candidum was isolated from postmortem culture specimens. The emergence of this organism as an occasional pathogen in leukemic patients is of interest and illustrates the importance of obtaining fungal cultures. There is a need for more effective drugs for antifungal prophylaxis and therapy.

Non-Hodgkin's lymphomas in the Middle East. A study of 417 patients with emphasis on special features.

A total of 417 evaluable patients with non-Hodgkin's lymphomas were diagnosed between January 1974 and December 1983 at the American University of Beirut Medical Center in Beirut, Lebanon. Of these, 179 (43%) patients had nodal lymphomas, and 183 (44%) had extranodal lymphomas. The commonest lymphoma was diffuse large cell (27%), followed by large cell immunoblastic (21%). The histopathologic pattern was follicular in 18% of the nodal lymphomas and in 5.3% of the extranodal forms. The most common site of extranodal lymphoma was the gastrointestinal tract (46.5%), followed by Waldeyer's ring (19%). Small intestinal lymphomas were three times more common than gastric lymphomas. Immunoproliferative small intestinal disease (IPSID) was diagnosed in 20 of 59 patients who had primary small intestinal lymphoma. Of the 34 patients who had Waldeyer's ring lymphoma, 7 had gastrointestinal involvement at some time during the course of the disease. Nodal lymphomas were associated with poor prognostic factors: 82% were diffuse; 77% had advanced disease at presentation; 77% had intermediate- or high-grade malignancy lymphoma; 40% had marrow involvement; and 46% had B symptoms. In children, the most common lymphoma was Burkitt's, and 80% of pediatric lymphomas were high-grade malignancy. In conclusion, this study delineates the special features of non-Hodgkin's lymphomas in the Middle East: The presence of IPSID; the high incidence of extranodal forms, in particular the intestinal ones; and the rarity of follicular lymphomas.

Fusarium. A newly recognized fungal pathogen in immunosuppressed patients.

Two cases of disseminated fungal infection due to Fusarium species, that occurred during a 4-month period, are reported. Both patients had a myeloproliferative disorder for which they had received intensive cytotoxic and immunosuppressive therapy, and both died despite treatment with amphotericin B. This report and review of the recent literature suggest that Fusarium is emerging as a newly recognized fungal pathogen in immunosuppressed patients.

Burkitt's lymphoma in the Middle East. A study of 34 cases.

The clinical features of 34 patients with Burkitt's lymphoma diagnosed at the American University Medical Center (AUMC) are described. Ages ranged between 3 and 20 years (median, 7 years). Seventy-three percent of the patients were younger than 8 years. Three cases occurred among siblings. The primary site of disease at presentation was the abdomen, 23 patients; jaw, 6; jaw and abdomen, 2; Waldeyer's ring, 2; and mediastinum, 1. Of those who had abdominal disease, the involvement was diffuse and extensive in abdomen and pelvis in 9, apparently confined to the ileocecal region in 5, mesenteric nodes and small intestine in 5, large intestine in 1, and ovary in 3. One patient presented with paraplegia. The bone marrow was studied in 19 patients; it was positive in 5 and suspicious in 2. None had frank leukemia. CSF was studied in 4 patients at presentation and was negative. Eight patients developed meningeal lymphoma during the course of the disease. Liver involvement was documented in 3 patients. Peripheral lymphadenopathy was observed at presentation in 11 patients (9, neck; 2, inguinal + axillary). In contrast to African Burkitt's, the majority of our patients presented with abdominal disease, and in contrast to the American form, our patients were younger with a median age similar to that of African Burkitt's. Thirty percent of the patients had jaw tumor at presentation--a figure intermediate between the African and the American Burkitt's.

Burkitt's lymphoma in the Middle East.

The clinical features of 30 retrospectively diagnosed cases of Burkitt's lymphoma (BL) at the American University Medical Center (AUMC) in Beirut differed from those of African Burkitt's in that the majority of the AUMC patients presented with abdominal disease, and from the American form, in that the AUMC patients were younger, with a median age similar to that of African BL patients.

Reserpine in propranolol-resistant thyroid storm.

beta-Adrenergic blockers are considered the drugs of choice in the management of the hyperadrenergic state in hyperthyroidism. However, we observed a patient in thyroid storm and coma who failed to respond to large doses of oral and intravenous propranolol hydrochloride but who responded promptly to intramuscular reserpine. Reserpine may have been lifesaving and should be considered in propranolol-resistant hyperthyroidism and in hyperthyroid patients in whom propranolol is contraindicated.

Hansenula anomala fungemia.

Fungi of the genus Hansenula have rarely been reported as pathogenic in humans. A case of catheter-related Hansenula anomala fungemia in a patient with acute leukemia in remission is presented, and the clinical features of 11 additional patients infected with Hansenula species are reviewed. The spectrum of disease with these organisms ranges from asymptomatic fungemia to life-threatening disseminated infection. Predisposing factors appear to be immunosuppression, use of intravenous devices, and previous treatment with antibacterial drugs. Clinical experience and limited in vitro susceptibility data show that amphotericin B remains the drug of choice in the treatment of hansenula infections.

New spectrum of fungal infections in patients with cancer.

We report on 44 cancer patients who had serious infections with unusual fungal pathogens and who were cared for at our cancer center between 1974 and 1986. Twelve different fungal species accounted for these infections, including Trichosporon beigelii, Fusarium species, Geotrichum candidum, Curvularia species, Drechslera species, Penicillium species (but not Penicillium marneffei), Rhodotorula rubra, Pseudallescheria boydii, Pichia farinosa, Torulopsis pintolopesii, Saccharomyces cerevisiae, and Cunninghamella bertholletiae. Skin lesions were noted in seven patients, and sinusitis occurred in four. Twenty-four patients had disseminated infection, 12 had involvement of a single organ, and eight had fungemia alone. Features that correlated with a poor prognosis were persistent neutropenia and disseminated visceral infection but not fungemia alone. We suggest that unusual fungi have now emerged as significant pathogens in this patient population. Fungal sinusitis, previously caused by Aspergillus species and the phycomycetes, also occurs as a result of some of these newly recognized fungi. A high level of suspicion should be maintained when any of these unusual fungi are cultured from clinical specimens from immunocompromised patients.

Effectiveness of cisplatin in the treatment of anal squamous cell carcinoma.

The therapeutic activity of cisplatin was explored in three consecutive patients with locoregional squamous cell carcinoma of the anus who received no prior therapy. One complete response and two partial responses were achieved. These data, although preliminary, strongly suggest that this disease is sensitive to cisplatin, and further trials are indicated to assess the precise role of this drug in the overall management of anal carcinoma.
