We evaluated the efficacy and safety of and compliance with rH-EPO (150 U/kg three times a week subcutaneously for up to 12 weeks) for treatment of anemia in childhood Crohn's disease (n = 4). The mean hemoglobin level before rH-EPO therapy was 109 gm/L (10.9 gm/dl) (range, 103 to 115 gm/L). The mean hemoglobin level in the three compliant children increased to 138 gm/L (13.8 gm/dl) after treatment. Response time for the correction of anemia ranged from 6 to 12 weeks (mean, 9.5 weeks). Resolution of symptoms of lethargy, poor appetite, and irritability occurred with correction of the anemia. The only adverse effect observed was transient local pain at the injection site.

A 4-year-old Rhodesian Ridgeback had acute onset of vomiting, lethargy, and discolored urine. Physical examination revealed lethargy, pyrexia, weak femoral pulses, cardiac arrhythmia, distended abdomen, and signs of pain on abdominal palpation. Abdominal radiography and ultrasonography revealed a gas-containing lesion in the cranial portion of the abdomen. Preoperative care included administration of fluids, antibiotics, and antiarrhythmic medication. Exploratory laparotomy revealed hemobilia and a 360 degrees clockwise torsion of the papillary process of the caudate lobe of the liver. Clinical signs resolved completely after liver lobectomy, and the dog was alive 2 years after surgery. Torsion of a liver lobe is rare in dogs. Necrosis of the involved liver lobe can result in acute weakness, shock, and death. Hemodynamic stabilization, antibiotic treatment, and surgical intervention have been successful in treating this condition. Liver lobe torsion should be considered on the differential diagnoses list of acute abdominal pain.

A 9-year-old spayed female Poodle was admitted because of vomiting of 3 weeks' duration, lethargy, and anorexia. Palpation of the cranial portion of the abdomen elicited signs of pain. Principal laboratory abnormalities included mild segmented neutrophilia, lymphopenia, high serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities, and hyperbilirubinemia. Radiography revealed foamy appearing areas of mineral opacity in the region of the gallbladder. Ultrasonographically, a hyperechoic structure with acoustic shadowing was seen in the same region, and extrahepatic bile ducts were distended. Cholecystectomy was performed. The gallbladder wall felt thicker than normal and was bluish-white. Multiple choleliths were found in the gallbladder and extrahepatic bile ducts. Histologic examination revealed chronic proliferative lymphoplasmacytic cholecystitis with mineralization and a well-differentiated adenocarcinoma of the gallbladder neck. A diagnosis of porcelain gallbladder was made. The dog recovered without complications and was healthy 14 months after surgery. To our knowledge, porcelain gallbladder has not been reported in dogs. In human patients, it is defined as intramural mineralization of the gallbladder commonly associated with gallbladder neoplasia. Early recognition is important for appropriate surgical treatment.

Free tick identification has been offered by our laboratory since 1989, during which time > 8,000 specimens have been submitted. We have noted that the bite of 1 of the less frequently identified ticks, Ixodes muris Bishopp & Smith, may be associated with a severe reaction in domestic animals characterized by extreme pain and swelling at the site and, with more complete engorgement, lethargy, anorexia, and high fever. These symptoms may be confused with other serious illness if the tick is not found. This reaction has not been seen following the bite of other species of ixodid ticks in Maine. Here we report 43 such cases, most involving dogs and cats from which ticks were removed by veterinarians and submitted to our laboratory for identification. Although I. muris was initially widespread in the United States and eastern Canada, its current range is unclear. In view of the potential for severe reaction to the bite of I. muris, the current distribution of the tick needs better definition, as does the mechanism of this response in animals that are unnatural hosts.

A 7-month-old child presented to the emergency department (ED) with 2 hours of painless, nonprojectile emesis and a normal mental status. Over a 3-hour period in the ED, the child remained pain-free, but developed hematemesis, hematochezia, and lethargy, progressing to unresponsiveness. The patient was evaluated for toxic ingestion, intracranial bleed, sepsis/meningitis, and intraabdominal pathology. The diagnosis was made by an abdominal ultrasound, which demonstrated an ileal-cecal intussusception that ultimately required surgical reduction. This case illustrates an insidious and poorly understood presentation of a common childhood affliction, as well as the utility of abdominal ultrasound in evaluating a hemodynamically stable patient with intussusception.

Twenty-five patients with high-risk resected stages IIB, III, and IV melanoma were immunized with a vaccine consisting of the minimal epitope, immunodominant 9-amino acid peptide derived from the MART-1 tumor antigen (AAGIGILTV) complexed with incomplete Freund's adjuvant. The last three patients received the MART-1(27-35) peptide with incomplete Freund's adjuvant mixed with CRL 1005, a block copolymer adjuvant. Patients were immunized with increasing doses of the MART-1(27-35) peptide in a Phase I trial to evaluate the toxicity, tolerability, and immune responses to the vaccine. Immunizations were administered every 3 weeks for a total of four injections, preceded by leukapheresis to obtain peripheral blood mononuclear cells for immune analyses, followed by a post-vaccine leukapheresis 3 weeks after the fourth vaccination. Skin testing with peptide and standard delayed-type hypersensitivity skin test reagents was also performed before and after vaccinations. Local pain and granuloma formation were observed in the majority of patients, as were fevers or lethargy of grade 1 or 2. No vaccine-related grade III/IV toxicity was observed. The vaccine was felt to be well tolerated. Twelve of 25 patients were anergic to skin testing at the initiation of the trial, and 13 of 25 developed a positive skin test response to the MART-1(27-35) peptide. Immune responses were measured by release of IFN-gamma in an ELISA assay by effector cells after multiple restimulations of peripheral blood mononuclear cells in the presence of MART-1(27-35) peptide-pulsed antigen-presenting cells. An ELISPOT assay was also developed to measure more quantitatively the change in numbers of peptide-specific effector cells after vaccination. Ten of 22 patients demonstrated an immune response to peptide-pulsed targets or tumor cells by ELISA assay after vaccination, as did 12 of 20 patients by ELISPOT. Nine of 25 patients have relapsed with a median of 16 months of follow-up, and 3 patients in this high-risk group have died. Immune response by ELISA correlated with prolonged relapse-free survival. These data suggest a significant proportion of patients with resected melanoma mount an antigen-specific immune response against a peptide vaccine and support further development of peptide vaccines for melanoma.

Cytolytic and helper T cells recognize small peptide fragments of protein antigens that are intracellularly processed and delivered to the cell surface in conjunction with HLA molecules. In mice, peptide vaccines can protect against lethal virus infections and tumor challenges. To test whether epitope peptides derived from a human tumor antigen can induce immune responses in patients, a vaccine was prepared consisting of an HLA-A1-restricted epitope of the antigen MAGE-3 mixed with a pan-class II epitope peptide PADRE and emulsified with incomplete Freund's adjuvant. Eighteen patients with resected stages III and IV melanoma at high risk for relapse were vaccinated subcutaneously with increasing doses of the MAGE-3 vaccine ranging from 100 to 2,000 micrograms per injection four times, each 4 weeks apart. The purpose of the phase I trial was to assess the toxicity, tolerability, and immune responses to the vaccine. The vaccine was not toxic, with only one case of grade III lethargy, and most patients complaining of grade I or II local pain, swelling, and tenderness at the injection sites. Peripheral blood mononuclear cells (PBMC) were collected from most patients prior to and after vaccination and used for assessment of global levels of immunity prevaccination, and to measure immune responses to the MAGE-3 and PADRE peptides prior to and after vaccination. Significant defects in global immunity shown by anergy to DTH skin testing in 7 of 16 patients and decreased proliferation to PHA (phytohemagglutinin) and CASTA, a Candida albicans protein extract, were observed. Seven of nine patients showed an increased response to PADRE after restimulation in vitro. Five of 14 patients at doses from 100 to 2,000 micrograms demonstrated an immune response to MAGE-3 by cytolysis of MAGE-3-specific target cells. Release of gamma interferon by T cells from 8 patients at the 100, 1,000, or 2,000 micrograms dose was measured after vaccination, and only two of eight patients showed an increase indicating augmented antigen-specific immunity. These data suggest that immune responses can be detected against PADRE and MAGE-3 in vaccinated melanoma patients, albeit with a low frequency of effector cells.

A 20-month-old 1.44-kg (3.2-lb) castrated male ferret was examined because of vomiting, defecating in an abnormal location, dyspnea, and signs of depression. Within 5 minutes of initial evaluation, the ferret became nonresponsive to all stimuli except deep pain. Despite intensive supportive treatment, the ferret died. Toxicologic analyses for ibuprofen were performed on serum, urine, and liver, using gas chromatography and mass spectrophotometry. Serum ibuprofen concentrations were 245 micrograms/g before and 269 micrograms/g after death. Acute ibuprofen toxicosis may cause severe lethargy progressing to coma, apnea, and death in ferrets. Ibuprofen toxicosis should be considered in differential diagnoses for ferrets with signs of depression, with or without clinical signs of gastrointestinal tract dysfunction.

Cyclic vomiting syndrome (CVS) remains a mysterious disorder despite our increasing knowledge since its classic description by Gee in 1882. Its hallmark feature of recurrent, explosive bouts of vomiting punctuating periods of normal health causes substantial medical morbidity (50% of patients require intravenous therapy), as well as significant time lost from school (20 school absences per year) and work. Limited epidemiologic data indicate that CVS may occur more commonly than previously thought, affecting as many as 1.9% of school-aged children. Besides the relentless vomiting, the child usually has pallor (87%), lethargy (91%), anorexia (74%), nausea (72%), and abdominal pain (80%). There is evidence of clinical and physiologic overlap among CVS, abdominal migraine, and migraine headaches. We propose revised criteria for abdominal migraine that include pain as the predominant and consistent symptom, lack of abnormal screening tests, and in retrospect, either subsequent development of migraines or positive response to antimigraine medication. Besides migraines, other etiologic possibilities include mitochondrial DNA mutations, ion channelopathies, excessive hypothalamic-pituitary-adrenal axis activation, and heightened autonomic reactivity. The differential diagnosis includes idiopathic CVS (88%); gastrointestinal disorders (7%), including serious surgical disorders (e.g., malrotation); and extraintestinal disorders (5%), including serious surgical (brain stem neoplasm) and metabolic disorders (e.g., fatty acid oxidation disorder). Within the idiopathic group, there may be migraine, Sato's neuroendocrine, mitochondrial, and other subgroups. Treatment includes avoidance of triggers, prophylactic medication, supportive care, abortive medication, and family support. In the future, investigation into mitochondrial DNA mutations, ion channel defects, corticotropin-releasing factor, and serotonin and tachykinin receptor physiology and pharmacology may help discover the etiology and pathogenesis of this disorder.

The randomized clinical trial, LU19, conducted by the Medical Research Council Lung Cancer Working Party, was designed to compare ACE (doxorubicin, cyclophosphamide and etoposide) chemotherapy plus G-CSF (granulocyte colony-stimulating factor) at 2-week intervals versus ACE chemotherapy alone at standard 3-week intervals in patients with small-cell lung cancer. This trial investigated whether more intensive administration of ACE would improve overall survival and affect the quality of life of patients. The report on overall survival and other outcome measures will be published in the Journal of Clinical Oncology. In this paper we focus on methods of analysing aspects of data reflecting quality of life. Twelve symptoms of lung cancer and its treatment - cough, haemoptysis, pain, nausea, vomiting, hoarse voice, sore mouth, rash, lethargy, lack of appetite, alopecia, and dysphagia - were scheduled to be assessed on seven occasions for the ACE arm and on eight occasions for the ACE+G-CSF arm by clinicians during the first 18 weeks of the treatment period. However, in practice the number of assessment forms completed per patient ranged from 1 to 9, and assessment time-points were very different from those planned. These 'messy' longitudinal data are explored by both a summary measure approach, in which experience of a symptom is summarized by a single value, and an extensive model-based statistical approach, which explicitly takes into account correlation within repeated measures. These analyses provide a clear picture of symptom comparisons between the two treatments. The application of various methods offers not only an approach to assessing the robustness of the results but also a basis for investigating reasons for inconsistency of results across methods. We conclude that except lethargy, which is worse in the ACE+G-CSF arm, all symptoms are similar across the two arms during the treatment period.
