Pelizaeus-Merzbacher disease (PMD) is a hereditary disorder with myelin dysplasia in the central nervous system. The connatal type is a more severe form compared to the classical type and shows developmental arrest or deterioration, nystagmus, spasticity, and/or convulsions in the neonatal period.
A 1
1/4-year-old Japanese boy diagnosed as connatal type PMD is reported here. Soon after his birth, he demonstrated horizontal and rotatory nystagmus and opisthotonic posture. At the age of 10 months, he had difficulty in feeding. At the age of 1 year, he presented more severe opisthotonic posture and frequent
vomiting
. He showed deterioration in gross motor development. His chromosome analysis showed a normal male karyotype. Electroencephalogram did not show a sleep spindle. Auditory evoked brainstem responses (ABR) showed only wave I on both sides. Visual evoked potentials (VEP) showed prolongation of latencies. These results were compatible with PMD. Nuclear magnetic resonance imaging (MRI) demonstrated in the white matter of cerebrum and brainstem no high intensities on T1-weighted images and diffuse high intensities on T2-weighted images. Such absence of myelination including the brainstem was characteristic to the connatal type PMD. The diffuse disturbance of myelination appeared to correlate with the severity of clinical symptoms.

A 1
.5-year-old Dalmatian was examined because of
vomiting
, weight loss, and high serum activities of alanine aminotransferase and aspartate aminotransferase. Abdominal ultrasonography revealed normal appearing hepatic structure with echogenicity, but histologic examination of hepatic biopsy specimens revealed extensive necrosis of hepatocytes involving the centrilobular areas. Macrophages and remaining hepatocytes contained pigments that were positive for copper by rubeanic acid-staining and hepatic copper concentration was high. The dog was treated with crystalloid fluids, antibiotics, and a low copper diet; its condition deteriorated, and the dog was euthanatized. Primary copper storage disease was suspected on the basis of histologic findings and high copper concentration in the liver.

A 1
.5-month-old boy with Sandifer's syndrome is described. After an uneventful delivery, he presented torticollis, seizure-like dystonic neck movements usually associated with feeding, episodic
vomiting
, inspiratory stridor and hand tremor in the first month of life. Barium esophagogram demonstrated gastroesophageal reflux, for which medical therapy was started. Children with torticollis and dystonic movements should be evaluated for Sandifer's syndrome. Early diagnosis and treatment of gastroesophageal reflux may prevent complications.

A 1
-year 7-month-old boy presented with sudden onset of severe
vomiting
and abdominal pain. Barium enema revealed the caecum was elevated by a mass and the ileocaecal junction was visualised with a very short segment of terminal ileum showing a 'bird's-beak' appearance. At surgery, an unusually long necrotic appendix knotting the terminal ileum resulted in strangulation of a segment of the terminal ileum. There was no evidence of torsion of the terminal ileum or appendix. To our knowledge, this is the first case of the appendix knotting the terminal ileum resulting in a strangulated closed-loop obstruction.

A 1
-day-old female infant presented with
vomiting
immediately after feeding and shortness of breath after birth. Esophagography revealed external compression of the esophagus. Echocardiography showed a right aortic arch with mirror image branching of brachiocephalic vessels without intracardiac anomalies. Left ventriculography confirmed the echocardiography findings and revealed a tenting of the proximal part of the left subclavian artery and a blind pouch of Kommerell diverticulum at the descending aorta. The patient underwent surgery, which revealed a complete vascular ring compressing the trachea and the esophagus. The ring was formed by a right aortic arch, atretic left arch and left ligamentum arteriosum. Following surgical division of the ligamentum arteriosum and the atretic left arch, the symptoms subsequently improved.

Acute zinc poisoning has been observed in dogs following the ingestion of metallic zinc objects.
A 1
1/2-y-old female miniature bull terrier exhibiting anorexia,
vomiting
, depression, fever (39.9 C), icterus and intravascular hemolysis was diagnosed with acute zinc poisoning. Anemia, Heinz body production, azotemia and bilirubinemia were also evident. Abnormal pancreatic, hepatic and renal functions were also apparent. A radio opaque object was observed in the stomach. Based upon an elevated plasma zinc level of 28.6 ppm, a tentative diagnosis of zinc poisoning was made. Following surgical removal of the metallic zinc object, a blood transfusion and fluid therapy were given to restore the normal blood volume. Heparin, Cephazolin and Raniditine were also given, although chelation therapy was not provided. Zinc levels in the plasma declined in a steady fashion (half-life = 7.6 d). Complications, such as disseminated intravascular coagulation, chronic pancreatitis, renal or hepatic failure, were not observed. By 20 d post surgery, only mild elevation of liver enzymes was evident. Measurements of the half-life of zinc may provide a useful indication of prognosis and the success of treatment.

We have reported that increasing the length of infusion from 5 min to 1 h appeared to substantially reduce the toxicity associated with fluorouracil (5-FU) modulated by leucovorin (LV) and interferon alpha-2a (IFN-alpha). This phase II study assessed the antitumor efficacy of this regimen. Patients (n=38) with colorectal cancer received IFN-alpha 5 MU/m(2) SC on days 1-6; on days 2-6, LV 200 mg/m(2) IV was given with 5-FU at initial doses of 370-425 mg/m(2)/h. The regimen was well-tolerated with no grade 4 toxicity. At 425 mg/m(2) 5-FU, grade 3 toxicities included diarrhea (8.6%), anorexia, fever and fatigue (5.7% each), neutropenia and nausea/
vomiting
(2.9% each). Individuals tolerated 5-FU doses up to 644 mg/m(2). Objective responses occurred in 27% of 37 patients; median time to progression and survival were 6.1 and 12.9 months. Only 1 of 25 informative tumor samples had high-frequency microsatellite instability (MSI), while 7 of 23 assessable patients (30%) with MSI-negative tumors had an objective response. With 425 mg/m(2), the average 5-FU Cp and AUC(0-1 h) were 37.4 microM and 1161 microM/h. Some 6 patients had extended sampling, and the half-lives of 5-FU and FBAL (apparent) were 8.6 and 100.0 min, respectively.
A 1
-h infusion of 5-FU is well tolerated; individual dose escalation of 5-FU allows each patient to receive the maximum tolerable dose.

Total body irradiation (TBI) is an important part of bone marrow transplantation conditioning regimens. In TBI, dose escalation is difficult, because of associated normal organ toxicities. A method to deliver a more targeted dose of TBI preferentially to sites of greatest tumor burden is needed to reduce the dose to normal organs, reduce toxicities, and permit dose escalation. The purpose of this study was to evaluate, through a dosimetric analysis, the potential advantages and feasibility of selectively delivering targeted myeloablative doses of radiation to bone and marrow using a recently developed image-guided tomographic intensity-modulated radiation therapy delivery system (helical tomotherapy). Whole-body computed tomography datasets from 3 patients, age 5, 20, and 53 years, were used for treatment planning studies to evaluate 2 targeted TBI strategies: total marrow irradiation (TMI), in which the target region was defined as the skeletal bone, and total marrow and lymphoid irradiation (TMLI), in which the target regions were defined as bone, major lymph node chains, liver, spleen, and sanctuary sites, such as brain. Organ doses and dose distributions were compared with those in conventional TBI.
A 1
.7- to 7.5-fold reduction in median organ doses was observed with TMI and TMLI compared with conventional TBI. With this more targeted approach, a dose-volume histogram analysis predicted the potential to escalate the dose to bone (and containing marrow) up to 20 Gy, while maintaining doses to normal organs at lower levels than in conventional TBI to 12 Gy. Results were similar for the adult and pediatric patients, indicating that this form of targeted TBI will be applicable to most patients regardless of frame size. TMI to 10 Gy was delivered as part of a tandem transplant regimen to the 53-year-old patient with multiple myeloma. Clinical results confirmed the treatment planning predictions. After TMI, the patient experienced the expected blood count nadir, followed by successful engraftment. Grade 2 nausea and grade 1
emesis
occurred only briefly on day 2 of TMI. Skin erythema, oral mucositis, esophagitis, and enteritis were not observed. This report demonstrates the feasibility and potential dosimetric advantages of selectively delivering myeloablative doses of radiation to bone and marrow using an image-guided tomographic intensity-modulated radiation therapy delivery system. Organ doses are substantially lower than those associated with standard TBI and predict the potential to significantly reduce associated toxicities and allow for dose escalation. The results also suggest that this form of targeted TBI may have potential advantages over other forms of targeted TBI, such as radioimmunotherapy or bone-seeking radionuclide therapy. Ongoing clinical trials will define the maximum TMI and TMLI doses achievable and define the potential advantages and limitations of this new approach for patients undergoing hematopoietic stem cell transplantation.

A 1
-year-old intact female miniature Dachshund was presented with hematochezia,
vomiting
, and diarrhea of more than 1-week duration. An abdominal mass was palpated, which at exploratory surgery was found to be a 7-cm-long thickened section of ileum. The thickened ileum was resected. Impression smears revealed numerous small- to medium-sized lymphocytes, with a smaller number of cells resembling Mott cells. The Mott-like cells contained multiple pale vacuoles that were positive for periodic acid-Schiff (PAS) in wet-fixed smears, consistent with Russell bodies. Histologic evaluation of the surgically excised ileum revealed 2 populations of neoplastic lymphoid cells. The majority were uniform medium-sized lymphocytes with hyperchromatic oval or round nuclei and inconspicuous nucleoli. The remaining cells resembled Mott cells, which contained several PAS-positive eosinophilic globules in the cytoplasm, occasionally compressing the nucleus. The majority of neoplastic cells stained positively for vimentin, CD20, CD79a, and Pax-5, but were negative for CD3 and lysozyme; 43.5% of cells stained positively for Ki-67. The Mott cells were strongly positive for immunoglobulin but were negative for Pax-5. Using electron microscopy, a homogenous substance of intermediate electron density was observed frequently in the cisternae of rough endoplasmic reticulum in the cytoplasm of the Mott cells, and rarely in the perinuclear cisternae of the lymphoid cells, corresponding to the site of immunoglobulin staining. Monoclonal rearrangement of immunoglobulin heavy-chain (IgH) gene was observed by PCR testing for lymphocyte-antigen receptor rearrangement. The morphologic features, immunophenotype, and IgH gene rearrangement verified the lymphoid cells were neoplastic (mature cell type) and had a B-cell phenotype, with evidence of immunoglobulin production and differentiation into Mott cells. This case was unusual because of the age of the dog and because most intestinal lymphomas are T-cell phenotype. The Mott cell morphology also differed from typical mature B-cell lymphoma types and may be a unique B-cell lymphoma variant.

A 1
-year-old-female Yorkshire Terrier was referred to the Veterinary Teaching Hospital of the Autonomous University of Barcelona (VTH-UAB) (Spain) with a 6-month history of unilateral chronic proliferative conjunctivitis and intermittent
vomiting
and cough. Several medical and surgical treatment efforts to manage conjunctival lesions had resulted in no improvement of the clinical signs. Complete general and ophthalmic examinations revealed several proliferative 'wood-like' masses in the conjunctiva, oral cavity and an interscapular subcutaneous nodule. Conjunctival and buccal biopsies were performed as diagnostic procedures. A diagnosis of ligneous conjunctivitis was made on the basis of histopathology findings and clinical presentation. The only biochemical abnormalities found were severe proteinuria and low plasminogen activity in plasma. No other analytical abnormalities were observed. Topical treatment with heparin and anti-inflammatory and immunosuppressive drugs have controlled the ophthalmological clinical signs. To our knowledge, this is the first case report of a dog with plasminogen deficiency and ligneous conjunctivitis with a long survival period and 2-year follow-up.
