Abstract
A 10-day-old female southern white rhinoceros calf (Ceratotherium simum simum) was diagnosed with a patent urachus after urine was observed dribbling from the umbilicus. After being separated from its mother, the animal was sedated with i.m. butorphanol and anesthetized with isoflurane in oxygen for surgical correction of the patent urachus. Mild postoperative complications involved seroma formation and partial skin incision dehiscence, which necessitated three follow-up immobilizations for reevaluation and treatment of the surgical site. Histopathology did not reveal an infectious etiology as the cause for the complications or for the patent urachus. The etiology of the patent urachus in this animal remains undetermined. This report represents the first documented case of a patent urachus in a white rhinoceros.

Abstract
PURPOSE The aim of this study was to compare the performance of direct digital radiography and traditional dental radiography for the detection of proximal surface dental caries in the mixed dentition. METHODS 15 quadrants of extracted teeth, arranged from the primary canine to permanent first molar, were imaged using direct digital (Schick Technologies, Long Island City, NY, USA) and conventional films (D-speed and E-speed Plus; Eastman Kodak Co., Rochester, NY, USA). Five pediatric dentists viewed the images and scored the 270 proximal surfaces for presence of caries on a 5 point scale and extent of caries on a 4 point scale. The teeth were sectioned and viewed microscopically to determine the gold standard. Receiver operating characteristic (ROC) analysis and analysis of variance (ANOVA) were used to evaluate the viewer's performance for detecting proximal caries using the 3 different image receptor types. RESULTS Experienced examiners were significantly more accurate in diagnosis of proximal surface caries using either D-speed or E-speed Plus films than they were using the direct digital receptor. The mean areas under the ROC curve (Az) for the viewers were 0.7595 for D-speed film, 0.7557 for E-speed Plus film, and 0.5928 for the direct digital receptor. The results also indicated that selected viewers' accuracy increased when viewing the direct digital images a second time. CONCLUSION CCD based direct digital radiography was not as accurate as conventional film images for the purpose of diagnosing proximal surface caries in the mixed dentition. However, the results imply that with increased experience, direct digital images may be as accurate as conventional film based images for diagnosis.

Abstract
PURPOSE To determine the potential efficacy and toxicity of intravenous (i.v.) methotrexate (MTX) and mercaptopurine (MP) as postremission intensification treatment for children with B-lineage acute lymphoblastic leukemia (ALL) at higher risk to relapse. PATIENTS AND METHODS Eighty-three patients (age 1 to 20 years) with higher-risk B-lineage ALL were entered onto this protocol. Following standard four-drug remission induction, 80 patients received 12 intensive 2-week cycles of MTX/MP: MTX 200 mg/m2 i.v. push, then 800 mg/m2 i.v. 24-hour infusion on day 1; MP 200 mg/m2 i.v. in 20 minutes, then 800 mg/m2 i.v. 8-hour infusion day 2; MTX 20 mg/m2 intramuscularly day 8; and MP 50 mg/m2 by mouth days 8 to 14. Age-based triple intrathecal therapy (MTX, hydrocortisone, and cytarabine) was administered for CNS prophylaxis. Continuation therapy was weekly MTX/MP (as on days 8 to 14) for 2 years. RESULTS Eighty-one patients (98%) entered remission. There were 28 relapses (marrow, n = 11; marrow and CNS, n = 2; isolated CNS, n = 9; testes, n = 5; ovaries, n = 1). No overt relapse occurred during the intensive phase of therapy. The event-free survival (EFS) rate at 4 years is 57.4% +/- 9.1% (SE). Hematologic, mucosal, and infectious toxicities were seen in 12%, 9%, and 5% of intensive MTX/MP courses, but were generally mild. CONCLUSION Combined data from this and our previous trial suggest that intensive MTX/MP may produce long-term disease-free survival in 70 to 75% of children with B-lineage ALL. In comparison to other intensive regimens, intensive MTX/MP is easy to administer, effective, and relatively nontoxic. If patients at risk for failure of MTX/MP can be identified prospectively, more aggressive regimens could be restricted to this smaller (25% to 30%) cohort.

Abstract
The association between radiographic evidence of mandibular asymmetry and history of prepubertal trauma was analyzed in orthognathic surgery patients and orthodontic patients. There were statistically significant associations between radiographic evidence of mandibular asymmetry and a history of prepubertal trauma in both patient groups. The results suggest that prepubertal trauma could be one etiologic factor for the development of mandibular asymmetry.

Abstract
BACKGROUND To prevent drug resistance, the authors designed a protocol that featured early intensive rotating drug pairs as part of the therapy for acute lymphoblastic leukemia (ALL). METHODS After prednisone, vincristine, asparaginase, and daunorubicin induction, 12 intensive treatments (ABACABACABAC) were given in 30 weeks: A--intermediate-dose methotrexate (IDMTX) plus intermediate-dose mercaptopurine (MP); B--cytosine arabinoside (AC) plus daunorubicin (DNR); C--AC plus teniposide (VM-26). Triple intrathecal chemotherapy (AC, MTX, and hydrocortisone) was given for central nervous system (CNS) prophylaxis. Continuation therapy consisted of weekly MTX and daily MP until 2.5 years of continuous complete remission had been achieved. RESULTS Seventy-four children (age range, 1-19 years) at high risk of relapse were treated. Of 55 with B-lineage (early pre-B, pre-B) ALL, 24 have failed (2 induction failures, 2 deaths from infection, and 20 relapses). The event-free survival (EFS) rate at 4 years was 55.5% (standard error [SE] +/- 7.7%). Of 19 patients with T-cell ALL, 12 have failed (2 induction failures and 10 relapses). The EFS rate at 4 years was 32.6% (SE +/- 26.8%). Toxicities were significantly more common after AC and DNR or AC and VM-26 than IDMTX and MP. There were no toxicity-related deaths during intensive treatments. CONCLUSION Early intensive rotating therapy is tolerable and warrants consideration for additional trials of patients with high-risk, B-lineage ALL.

Abstract
The safety of licensed influenza virus vaccine (IVV) combined with a novel adjuvant containing muramyl tripeptide (MTP) conjugated to phosphatidylethanolamine (PE) was evaluated in a randomized pilot study. Ten healthy 23-30-year-old men were given a single intramuscular dose of IVV combined with saline (n = 5) or with 100 micrograms of MTP-PE in the MF59 adjuvant emulsion (MF59-100) (n = 5). Evaluations were performed on days 0, 1, 2, 4, 7 and 28 after inoculation. IVV alone was well tolerated. All volunteers immunized with IVV/MF59-100 experienced moderate to severe local and systemic reactions which interfered with usual activities. Discomfort at the injection site was first noted at 2-6 h; induration (5/5), erythema (3/5), and regional adenopathy (3/5) persisted for up to 4 days. Systemic symptoms including chills (5/5), fever (3/5), nausea (3/5) and/or dizziness (2/5) developed within 12 h of inoculation and resolved by 48 h. Elevated white blood cell count (days 1 and 2), erythrocyte sedimentation rate and serum fibrinogen were transiently observed. Although peak serum neutralizing antibody titres versus influenza A/H3N2 and influenza B antigens were higher in the group given IVV with MF59-100, these unexpected reactions indicate that this dose of adjuvant is unsuitable for use in combination with this IVV.

Abstract
The isolation of measles virus in primary Rhesus monkey kidney cells (PRMK) in patients with documented giant-cell pneumonia who have presented without a rash is limited. The diagnosis usually is made by cytologic examination of nasal or bronchial secretions in which characteristic multinucleated giant cells with intranuclear and intracytoplasmic inclusion bodies are observed. The diagnosis of giant-cell pneumonia has been associated with measles virus but not exclusively. Canine distemper, herpes group viruses, and parainfluenza infections have been associated with these cells. In addition, vitamin A deficiency also has been cytologically associated with multinucleated giant cells. The authors describe the isolation of measles virus from bronchial washing and sputum in PRMK cells at 4 days from an 11-year-old child with acute interstitial pneumonia who was in remission for acute lymphocytic leukemia. Classic cytopathologic effect (CPE) consisting of syncytial and hole formation on the PRMK monolayer was apparent. In addition, a foamy appearance of the monolayer was noted in an otherwise clean lot of monkey cells. Confirmatory testing with measles antibody of the infected areas of the monolayer by indirect immunofluorescence (IFA) was positive for measles antigen and negative for mumps, parainfluenza (types I, II, and III) and influenza A and B virus. Serologic studies for measles antibody revealed an IFA IgG titer of greater than 1:10,240, and an IgM titer of 1:128. Cytologic examination of the same bronchial fluid revealed the typical giant cells with characteristic inclusions associated with measles virus. Because this disease usually is severe, and often fatal, prompt recognition of this virus is essential, not only to the patient, who can be treated with immunoglobulin and/or antiviral therapy, but also to prevent the spread of the virus to other patients and medical personnel. These findings also support direct evidence for the etiologic role of measles virus in giant-cell pneumonia that has been detected either histologically or cytologically and in tissue culture at autopsy.

Abstract
Two stallions had unilateral bacterial epididymitis attributable to S zooepidemicus infection. Diagnosis was based on bacterial isolation, WBC in the semen, higher than normal blood fibrinogen concentration, and leukocytosis with regenerative left shift. One horse had high seminal pH. Ultrasonography of the involved epididymides revealed changes consistent with the appearance of abnormal accumulation of exudate in the tail of the epididymis. Treatment included unilateral orchiectomy and antibiotic administration. In stallion 1, the infection persisted despite treatment. Treatment result was not available for stallion 2.

Abstract
Methotrexate (MTX) and mercaptopurine (MP) are the mainstays of continuation therapy for acute lymphocytic leukemia (ALL). These drugs are stored in tissues as active metabolites. Relapse in ALL might reflect failure to achieve adequate intracellular drug levels. Assured (parenteral) delivery of higher doses of MTX and MP should maximize tissue levels of these drugs by overcoming individual variations in absorption, metabolism, clearance, and compliance. Fifty-nine children with ALL at lower risk of relapse received 12 intensive MTX/MP courses immediately after 4 weeks of standard vincristine, prednisone, and asparaginase induction. Each 2-week intensive course included: MTX, 200 mg/m2 intravenous (IV) push then 800 mg/m2 IV over 24 hours on day 1; MP, 200 mg/m2 IV push then 800 mg/m2 IV over 8 hours on day 2; MTX, 20 mg/m2 intramuscularly on day 8; and MP, 50 mg/m2 orally daily on days 8 to 14. After the 6 months of intensive therapy, continuation therapy was weekly MTX/MP (as on days 8 to 14) for 1 or 2 years. Age-based MTX was given intrathecally (IT) for CNS prophylaxis. All patients entered remission. Three patients relapsed: bone marrow (at 24 and 37 months), and bone marrow and CNS (at 34 months). There were no isolated CNS relapses or deaths in remission. Event-free survival at 4 years is 94% (SE, 7%) by Kaplan-Meier analysis. Toxicities (infection, mucositis) occurred in less than 10% of intensive MTX/MP courses. However, a child with Down's syndrome withdrew after three courses because of recurrent severe mucositis. Further studies of this regimen are in progress.

Abstract
We investigated the relationship of the presence of antibodies to HTLV-III and immunologic abnormalities in patients with hemophilia. Serum antibodies to HTLV-III were analyzed by ELISA assay, immunoprecipitation of labeled cell extracts, and immunoprecipitation of purified HTLV-III p24. Thirty-four (61%) of the total group (n = 56) had antibody to HTLV-III; 34 (76%) of 45 patients given commercial factor VIII preparations were seropositive, compared with none of 11 patients treated exclusively with cryoprecipitate obtained from volunteer blood donors. Of patients who were seropositive for HTLV-III antibody, 94% had abnormal T4/T8 ratios, and 33% of those whose serum was antibody negative had abnormal T4/T8 ratios; five patients, each antibody positive, have lymphadenopathy syndrome. Sequential studies in a subset of patients indicate that there is a changing pattern of antibody production to HTLV-III antigens after seroconversion.

Abstract
Doxorubicin plus vincristine chemotherapy was given to 31 children following nephrectomy for Wilms' tumor. Radiation therapy was used as indicated. Disease-free survival by stage is: eight of nine patients (stage I), eight of nine (stage II), nine of ten (stage III), and two of three (stage IV). Median follow-up of survivors is 28 months (range, 2-67); for all but four patients, follow-up is greater than 12 months. Two of the three stage I-III failures occurred in children with unfavorable histologies; the third failure was due to fatal anthracycline cardiomyopathy. Lowering the maximal cumulative doxorubicin dose from 450 to 240 mg/m2 did not increase failures. Doxorubicin-vincristine appears to be effective chemotherapy for Wilms' tumor.
