The relation between obesity and age in children with idiopathic intracranial hypertension (pseudotumor cerebri) has remained uncertain. The authors reviewed the records of 45 consecutive children with newly diagnosed idiopathic intracranial hypertension seen at two medical centers. Forty-three percent of patients aged 3 to 11 years were obese, whereas 81% of those in the 12- to 14-year age group and 91% of those in the 15- to 17-year age group met criteria for obesity (p = 0.01). Younger children with idiopathic intracranial hypertension are less likely to be obese than are older children or adults.

Four of 10 patients who were enrolled on protocols of high-dose immunosuppression with peripheral blood stem cell rescue for MS experienced neurologic worsening while receiving recombinant human granulocyte colony-stimulating factor. There was improvement when methylprednisolone was given to three of the patients, but one patient died of respiratory failure. The mechanism of the neurologic worsening is uncertain.

Summary:Self-administered questionnaires are commonly used to measure exposures and outcomes in epidemiological research and thus need good validity. With increasing numbers of cancer survivors, there is interest in the ongoing assessment of therapy-related complications. A medical record validation of patient-reported complications following bone marrow transplantation (BMT) was performed using a self-administered questionnaire. The study population consisted of 100 patients who had undergone BMT at the City of Hope. The following selfreported complications were validated using medical records: ocular, endocrine, cardiovascular, musculoskeletal, pulmonary, gastrointestinal, neurological, graft-versus-host disease, and subsequent cancers. Using information from medical records as the standard, sensitivities ranged from 52.9% for subsequent cancers to 100% for avascular necrosis and hypothyroidism. Specificities ranged from 75.4% for ocular complications to 100% for avascular necrosis. There was intermediate to excellent agreement (kappa = 0.4-1.0) for all complications evaluated. Thus, the agreement between self-reporting and medical records was good for complications with clear diagnostic criteria that are easily communicated to the patient, but was diminished for complications with non-established diagnostic criteria (xerophthalmia) or a fluctuating course (peripheral neuropathies and hypertension). Overall these results suggest that cancer survivors can selfreport serious complications with an acceptable level of accuracy in epidemiological research.

Between 1984 and 1997, 23 consecutive patients with Philadelphia chromosome-positive acute lymphoblastic leukemia in first complete remission were treated with allogeneic bone marrow transplants from HLA-matched siblings. All patients but one were conditioned with fractionated total body irradiation (1320 cGy) and high-dose etoposide (60 mg/kg). One patient received high-dose cyclophosphamide instead of etoposide, and another patient received both drugs. Nine patients died following BMT, two from relapsed leukemia, and seven from transplant-related causes. The 3-year probabilities of disease-free survival and relapse are 65% and 12%, respectively. For patients transplanted after 1992, these probabilities are 81% (48-95%, 95% confidence interval) and 11% (2-50%), respectively. The relatively low relapse rate in this group of patients compared to published reports may reflect the enhanced antileukemic activity of etoposide in combination with FTBI compared to other conditioning regimens. The enhancement in overall survival for patients transplanted after 1992 may reflect improvements in supportive care, in particular, the prophylaxis of serious fungal and viral infections.

The probability of survival is conventionally calculated from autologous hematopoietic cell transplantation (aHCT). Conditional survival takes into account the changing probability of survival with time survived, but is not known for aHCT populations. We determined disease-, and cause-specific conditional survival for 2388 patients treated with aHCT over a period of 20 years at a single institution. A total of 1054 deaths (44% of the cohort) were observed: 78% attributed to recurrent disease; 9% to subsequent malignancies; and 6% to cardiopulmonary disease. Estimated probability of relative survival was 62% at 5 and 50% at 10 years from aHCT. On the other hand, 5-year relative survival was 70%, 75%, 81%, and 88% after having survived 1, 2, 5, and 10 years after aHCT, respectively. The cohort was at a 13.9-fold increased risk of death compared with the general population (95%CI=13.1–14.8). The risk of death approached that of the general population for 10-year survivors (SMR=1.4, 95%CI=0.9–1.9), with the exception of female Hodgkin lymphoma patients transplanted before 1995 at age 40 years or younger (SMR=6.0, 95%CI=1.9–14.0). Among those who had survived 10 years, non-relapse-related mortality rates exceeded relapse-related mortality rates. This study provides clinically relevant survival estimates after aHCT, and helps inform interventional strategies.

Thirty-three patients with acute leukemia (15 with lymphoblastic leukemia and 18 with myeloblastic leukemia) were entered into a program of high-dose radiochemotherapy followed by allogeneic bone-marrow transplantation. These patients were in various clinical stages of disease. Of 10 in complete hematologic remission at the time of transplantation, seven were alive without maintenance therapy at the time of evaluation, eight to 35 months after grafting; one was in relapse. Of 11 who received transplants during partial remission, six were in remission without further treatment eight to 33 months after transplantation. In 12 the disease was refractory to chemotherapy when preparation for transplantation was started, and only one of them was alive and free of disease after 10 months. Recurrent leukemia, graft-versus-host disease, viral pneumonia, and early therapy-related toxicity were the major causes of failure. High-dose chemotherapy and total-body irradiation followed by allogeneic marrow transplantation performed during complete or partial remission can produce long-term remission of acute leukemia.
